Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the technical solution of the present application and are not intended to limit the present application.
For a better understanding of the technical solution of the present application, the following detailed description will be given with reference to the drawings and the specific embodiments.
At present, the primary vehicle-mounted central control is integrally considered when the vehicle is designed and produced, and the hardware interface of the primary vehicle-mounted central control is closely matched with other electronic systems, sensors and the like of the vehicle, so that various state information of the vehicle, such as vehicle speed, rotating speed, water temperature, oil quantity and the like, can be directly obtained. And the third party vehicle-mounted central control needs to spend a great deal of time and effort to study the electronic system architecture and hardware interfaces of different vehicle types, develop an adaptive connection module and ensure that the information can be accurately and stably acquired. For example, there may be differences in OBD (on-board automatic diagnostic system) interface data transmission protocols and electrical characteristics of different vehicle models, and third party central control needs to adapt to these differences, otherwise vehicle data may not be read normally or data errors may occur. Electronic systems in vehicles typically transmit and interact with data via a communication protocol such as a CAN (controller area network) bus. The communication protocol of the primary vehicle-mounted central control and the vehicle is completely matched, and the communication with each control unit of the vehicle can be smoothly carried out. Third party central authorities need to crack and understand these communication protocols in order to exchange data with other systems of the vehicle. However, security measures of automobile manufacturers on communication protocols make this process difficult, and communication protocols of different manufacturers and different vehicle types may have differences, which increases the difficulty and complexity of research and development. Therefore, the current third-party vehicle-mounted central control host machine can execute related actions after the vehicle is ignited and electrified, so that the use experience of the vehicle is affected.
The main solution of the application is that if a central control preloading instruction is detected, cache data stored at the last shutdown moment in a vehicle-mounted central control cache unit is obtained, at least two control types corresponding to the cache data are determined, rearrangement is carried out based on a control frame corresponding to the control types, an interface element file is determined, a vehicle three-dimensional model corresponding to a vehicle type is obtained, welcome pages are rendered according to the interface element file and the vehicle three-dimensional model, and carefully selected information corresponding to the cache data is synchronously broadcast. The technical effect of improving the rendering speed of the vehicle-mounted central welcome page is achieved.
It should be noted that, the execution body of the embodiment may be a vehicle-mounted central control, or may be a computing service device with functions of data processing, network communication and program running, such as a tablet computer, a personal computer, a mobile phone, or a welcome page broadcasting device capable of implementing the above functions, which is not limited in this embodiment. The present embodiment and the following embodiments will be described below using an in-vehicle center control as an execution subject.
Based on this, an embodiment of the present application provides a welcome page broadcasting method, referring to fig. 1, including steps S10 to S50:
Step S10, if the central control preloading instruction is detected, obtaining the cache data stored at the last shutdown time in the vehicle-mounted central control cache unit.
In this embodiment, the central control preloading instruction is triggered when it is determined that the user has an expectation of using the vehicle-mounted central control by collecting relevant data of the vehicle, so as to implement the welcome page broadcasting method in this embodiment. In a practical scenario, the trigger mechanism of the central preload instruction is multidimensional. When the car owner approaches the car, the intelligent key establishes close-range communication with the car, and the induction system of the car starts to work. If the vehicle door handle is pulled or the vehicle door unlocking signal is detected at the same time, the series of actions can be combined to judge that the user has extremely high possibility of using the vehicle-mounted central control, and then the central control preloading instruction is triggered. The design simulates the natural flow of the user getting on the car, and pre-judges the user demand in advance. The buffer unit is like a vehicle-mounted central control memory bank, and is a highly stable and specially designed storage area. At the instant of each vehicle flameout, the central control system will quickly package and store a series of key data thereto. The data comprise vehicle state data, such as readings of various sensors of the vehicle at flameout time, such as data of tire pressure sensors, engine oil temperature data and the like, and image content which is finally displayed by the vehicle-mounted central control at the time of stopping, such as multimedia information, navigation page information and the like. This design ensures that the vehicle can quickly return to the previous use state when it is restarted, reducing the waiting time of the user. The last shutdown time is the time when the vehicle was flameout last time. The cached data includes, but is not limited to, vehicle status data and the last displayed screen content of the on-board central control at the time of shutdown.
And step S20, determining at least two control types corresponding to the cache data.
In this embodiment, the control is a number of gadgets displayed on a display page of the in-vehicle center control. The control type is the type of gadget. Including but not limited to time, vehicle temperature, air conditioning temperature, and vehicle status data dashboards.
And step S30, rearranging based on the control frames corresponding to the control types, and determining interface element files.
In this embodiment, the control frame is a display frame corresponding to the control type, and the control is formed by filling cache data through the control frame. The interface element files are related data of the pages finally formed after all the control frames are arranged, and the processor renders the interface element files to display corresponding image contents on the display module.
And S40, acquiring a vehicle three-dimensional model which is prestored corresponding to the vehicle type.
In this embodiment, the three-dimensional model of the vehicle is a three-dimensional medium of the vehicle, and different views can be displayed in response to the touch operation of the user.
And S50, rendering welcome pages according to the interface element file and the vehicle three-dimensional model, and synchronously broadcasting carefully chosen information corresponding to the cache data.
As an alternative implementation manner, the central control preloading instruction is an instruction triggered when the user has the expectation of using the vehicle-mounted central control by collecting the relevant data of the vehicle. For example, whether the user has an expectation of using the in-vehicle center control may be determined by detecting data of an unlock state, a door open state, and the like of the vehicle. When such data is detected, the user may be considered to have the possibility of using the in-vehicle central control, triggering a central control preload instruction. The buffer memory unit is a storage area in the vehicle-mounted central control system and is used for storing buffer memory data at the last shutdown time. The cached data includes, but is not limited to, vehicle status data and the last displayed screen content of the on-board central control at the time of shutdown. The data can be quickly loaded when the vehicle-mounted central control is started next time, and the starting speed and the user experience are improved. The last shutdown time refers to the time when the vehicle was last turned off. At this time, the in-vehicle central control system stores the current vehicle state data and information such as display screen content in the buffer unit for use at the next start-up. When the central control preloading instruction is detected, the vehicle-mounted central control system can automatically acquire the cache data stored at the last shutdown time in the cache unit. These data can provide basic information for subsequent steps, helping to quickly build welcome pages and report selection information. The control is a plurality of gadgets displayed on a display page of the vehicle-mounted central control. For example, time, vehicle temperature, air conditioning temperature, vehicle status data dashboards, etc. are common controls. These controls may provide the user with various vehicle information and operational functions. The control type is the type of gadget. Different control types have different functions and display modes. For example, the time control may display the current time, the vehicle temperature control may display the temperature of the vehicle interior, the air conditioning temperature control may display the set temperature of the air conditioner, and so on. Based on the content of the cached data, a corresponding at least two control types may be determined. For example, if the cached data contains vehicle temperature and air conditioning temperature information, then the control type may be determined to be a vehicle temperature control and an air conditioning temperature control. After determining the control type, a specific control framework and display content can be provided for subsequent steps. The control frame is a display frame corresponding to the control type. Each control type has its particular display frame for populating the cached data forming the control. For example, the frame of the time control may be a display pattern of a digital clock, the frame of the vehicle temperature control may be a display pattern of a thermometer, etc. The interface element file is related data of a final formed page after all the control frames are arranged. The processor renders according to the interface element file, and then displays corresponding image content on the display module. Based on the control frames corresponding to the determined control types, the frames can be rearranged to determine an optimal page layout. The rearrangement process may take into account factors such as the user's usage habits, importance of information, etc. After the page layout is determined, an interface element file is generated to provide data support for the subsequent rendering step. The three-dimensional model of the vehicle is a three-dimensional medium of the vehicle, and different views can be displayed in a rotating manner in response to a touch operation of a user. The vehicle three-dimensional model can provide more visual vehicle appearance display for the user, and the use experience of the user is enhanced. And acquiring a pre-stored vehicle three-dimensional model according to the type of the vehicle. Different types of vehicles may have different three-dimensional models to ensure that the model matches the actual vehicle. After the three-dimensional model of the vehicle is obtained, the three-dimensional model of the vehicle can be combined with the interface element file to jointly render the welcome page. And rendering welcome pages according to the interface element file and the vehicle three-dimensional model, and synchronously broadcasting carefully chosen information corresponding to the cache data. Rendering the welcome page is combining the interface element file and the vehicle three-dimensional model to generate the final welcome page image content. The rendering process may use graphics processing techniques to fuse various controls with the vehicle three-dimensional model to present an aesthetically pleasing, practical welcome page. The selected information is important information extracted from the cache data, such as a fault prompt, an important notification, and the like of the vehicle. Such information may be synchronously broadcast on the welcome page to alert the user. And rendering welcome pages according to the interface element files and the vehicle three-dimensional model, and synchronously broadcasting carefully chosen information corresponding to the cache data. Therefore, when the user starts the vehicle-mounted central control, useful information and attractive interfaces can be provided for the user immediately, and the use experience of the user is improved.
Illustratively, the user owns an SUV-type vehicle and installs a third party on-board central control system. When the user unlocks the vehicle and opens the door, the in-vehicle central control system detects these actions and determines that the user is expected to use the in-vehicle central control, thereby triggering a central control preload instruction. The vehicle-mounted central control system acquires cache data stored at the last shutdown time in the cache unit, wherein the cache data comprise information such as the driving mileage, average oil consumption, current time, temperature in the vehicle, air conditioner setting temperature and the like of the vehicle. And determining the corresponding control types as mileage counter control, oil consumption display control, time control, vehicle temperature control and air conditioner temperature control according to the cache data. And rearranging based on the control frames corresponding to the control types to determine the interface element files. For example, the mileage counter control and the fuel consumption display control may be placed in the upper left corner of the page, the time control in the upper right corner of the page, and the vehicle temperature control and the air conditioning temperature control in the bottom of the page. Next, a pre-stored three-dimensional model of the vehicle is obtained based on the SUV type of the vehicle. This model may present the appearance of the vehicle on a welcome page and display different views in response to a user's touch operation rotation. And finally, rendering welcome pages according to the interface element files and the vehicle three-dimensional model, and synchronously broadcasting carefully chosen information corresponding to the cache data. For example, if the cached data contains a fault prompt message of the vehicle, the message can be synchronously broadcasted on the welcome page to remind the user of the fault prompt message.
Through the implementation manner and the embodiment, the power-on scheme of the third-party vehicle-mounted central control can be changed, and the use experience of a user is improved. When a user starts the vehicle-mounted central control, the cache data at the last shutdown time can be quickly loaded, and an attractive and practical welcome page is provided for the user by combining the vehicle three-dimensional model and carefully selected information.
The application provides a welcome page broadcasting method, which comprises the steps of firstly, when a central control preloading instruction is detected, obtaining cache data stored at the last shutdown time in a vehicle-mounted central control cache unit, determining at least two control types corresponding to the cache data, rearranging based on a control frame corresponding to the control types, determining an interface element file, obtaining a vehicle three-dimensional model corresponding to a vehicle type, rendering a welcome page according to the interface element file and the vehicle three-dimensional model, and synchronously broadcasting carefully selected information corresponding to the cache data. The technical problem that the current third-party vehicle-mounted central control host in the related technology can execute related actions only after the vehicle is ignited and electrified, and the use experience of the vehicle is affected is solved. The technical effect of improving the rendering speed of the vehicle-mounted central welcome page is achieved.
Based on any one of the above embodiments, a second embodiment of the present application provides a welcome page broadcasting method, including, before step S10, any one of the following steps:
and step S1, if the opening of the vehicle door and the pressure feedback of the front seat sensor are detected, judging that the central control preloading instruction is triggered.
In this embodiment, the door is opened, which means that the door of the vehicle is changed from a closed state to an open state. This can be detected by a sensor mounted on the door that senses a change in the mechanical motion of the door and transmits a signal to the on-board central control system. The opening of the vehicle door is an intuitive representation of the user entering the vehicle, and is one of the important bases for judging that the user is about to use the vehicle-mounted central control. Pressure feedback of front seat sensor, wherein the front seat is internally provided with a pressure sensor, and when an object applies pressure to the seat, the sensor can detect the change of the pressure value. When the pressure value exceeds a certain threshold value, the passenger sits on the front seat, and the information of the opening of the vehicle door is combined, so that the user can be more accurately inferred to prepare the vehicle to use, and then the central control preloading instruction is triggered.
In an actual scenario, when the vehicle owner opens the vehicle door to prepare for getting on and sits on the front seat, the vehicle door opening signal and the pressure feedback of the seat sensor are simultaneously received by the vehicle-mounted central control system, the system judges that the user has the intention of using the vehicle-mounted central control, and then a central control preloading instruction is triggered.
And step S2, if the ignition of the vehicle is detected, judging to trigger the central control preloading instruction.
In the present embodiment, vehicle ignition, which is an operation to start the engine of the vehicle, is achieved by an ignition switch. When the ignition switch is activated, a specific electrical signal is generated, which is recognized by an Electronic Control Unit (ECU) of the vehicle and executes a program for starting the engine. In this process, the on-board central control system can also detect this ignition signal as one of the conditions for triggering the central control preload command.
For example, the vehicle owner directly starts the vehicle after getting on the vehicle, the signal generated by the ignition action is captured by the vehicle-mounted central control system, and the system triggers the central control preloading instruction so as to prepare for the quick start of the central control system.
And S3, if the parking position of the vehicle is a garage and the light sensor detects illumination enhancement, judging to trigger the central control preloading instruction.
In this embodiment, the parking position of the vehicle is a garage, and the vehicle determines whether the vehicle is in the garage or not through a GPS positioning system or interaction information of a positioning facility related to the garage, such as a garage access control system. The garage environment is relatively closed and has certain specificity, and is one of scenes in which a vehicle owner frequently starts a vehicle. The light sensor detects the illumination enhancement, namely, the light sensor is arranged at a proper position on the surface of the vehicle and is used for detecting the illumination intensity of the surrounding environment. When the vehicle is in a garage, the light is typically darker. If the garage door is open or there is another light source causing the in-vehicle light sensor to detect a sudden increase in illumination intensity, this means that there may be a user entering the garage ready for use.
Assuming that the vehicle of the vehicle owner is parked in the self-home garage, when the garage door is opened, light irradiates into the vehicle, the light sensor detects the enhancement of the light, and the vehicle is combined with the information that the vehicle is located in the garage, the vehicle-mounted central control system triggers a central control preloading instruction.
And S4, if the current moment accords with the preference of the user for using the vehicle and the distance of the detected vehicle key is smaller than a distance threshold value, judging to trigger the central control preloading instruction.
In the embodiment, the current moment accords with the vehicle preference of the user, namely the vehicle-mounted central control system records the frequency and the rule of using the vehicle in different time periods by learning the vehicle habit of the user. For example, the system analysis finds that the vehicle owner has a high probability of using the vehicle at 7-8 a.m. and 6-7 a.m. on the workday, and these time periods are considered to be the moments that meet the user's preference for using the vehicle. The distance to detect the car key is less than a distance threshold, and the car is equipped with a car key detection system, typically based on bluetooth or other near field communication technology. When the distance of the vehicle key from the vehicle approaches to a certain extent (distance threshold), for example, in the range of 1-2 meters around the vehicle, the vehicle can detect the approach of the vehicle key. For example, at 7 a.m. for 30 minutes on weekdays, the time accords with the vehicle preference of the vehicle owner, and when the vehicle owner brings a vehicle key close to the vehicle, and the distance between the vehicle key and the vehicle is smaller than a set threshold value, the vehicle-mounted central control system triggers a central control preloading instruction.
Illustratively, a user starts a drive from a home garage to work about 7 and a half a day in the morning. The light in the garage is darker, and the vehicle knows that the vehicle is in the garage through the positioning system. In the morning, the vehicle owner opens the vehicle door into the vehicle, sits on the front seat, and the vehicle door opening signal and the pressure feedback of the front seat sensor are received by the vehicle-mounted central control system. At the same time, the light sensor of the vehicle detects that the illumination is enhanced after the garage door is opened. In addition, the system judges that the current moment accords with the vehicle preference of the vehicle owner according to the time, and the distance between the vehicle key carried by the vehicle owner and the vehicle is in the detection range. These conditions, taken together, trigger a central preload instruction. The vehicle-mounted central control system rapidly acquires the cache data stored at the last shutdown moment in the cache unit, starts subsequent welcome page broadcasting preparation work, and provides convenient and rapid vehicle-mounted central control use experience for vehicle owners. In other scenes, for example, a vehicle owner directly ignites on a parking lot or when approaching a vehicle for standby, the central control preloading instruction can be triggered as long as any trigger condition in the steps is met, so that the vehicle-mounted central control system can respond in time.
Therefore, the central control preloading instruction is triggered through preset conditions, and then the vehicle central control can be initially awakened before the vehicle is ignited, and the step of acquiring the cache data stored at the last shutdown moment in the cache unit of the vehicle central control is executed. The step only needs to acquire data, and does not need to consume great effort, so that the step can be completed through the background dormancy power consumption of the vehicle. The pre-acquisition of the data is realized through the use expectations of the expected users, and the rendering efficiency of welcome pages is improved.
Further, after the user ignites, the steps of determining at least two control types corresponding to the cached data and then are executed. If the vehicle is not ignited, the steps are not executed, so that the power consumption of the vehicle-mounted central control is reduced.
Based on any of the foregoing embodiments, a third embodiment of the present application provides a welcome page broadcasting method, referring to fig. 2, before step S10, including:
and step A10, if a vehicle stop instruction is detected, acquiring vehicle state data.
In this embodiment, the vehicle stop command refers to a signal that is issued when the vehicle is about to stop running. This signal may come from an ignition off operation of the vehicle or an internal command generated by the vehicle automatically determining that the current driving condition is in compliance with a stop condition, such as the vehicle being completely stationary, the engine being in an idle state for a period of time, etc. Vehicle state data the vehicle state data is descriptive of the operating state of various systems and components of the vehicle at the moment of shutdown. The method includes, but is not limited to, engine rotation speed, i.e. the value at the last moment before stopping, reflecting the working state of the engine and the speed of the vehicle, i.e. the speed at the moment of stopping, and confirming whether the vehicle is completely stationary, the residual fuel quantity, the electric quantity condition of a vehicle battery, the pressure value of each tire, the opening and closing state of each vehicle door, the state of a lighting system such as a headlight, a steering lamp, illumination in the vehicle, etc. are started, the fault code of the vehicle, etc. These data are important for the self-test at the next start of the vehicle and for the settings before restoration.
When the vehicle receives a stop command, the vehicle's control system will quickly collect these vehicle state data in preparation for subsequent cache storage.
And step A20, acquiring control data of a vehicle-mounted central control current interface.
In the embodiment, the control data of the vehicle-mounted central control current interface comprises a plurality of controls, and each control has specific data. For example, the data of the music playing control includes the name of the song currently played, the singer, the playing progress, the volume, the playing mode such as single-song circulation, random playing and the like, the data of the navigation control includes the current navigation destination, the distance travelled, the predicted remaining distance and the information of the next navigation prompt point, and if the data is the vehicle information display control, the data may include the display settings such as the display format, the unit and the like of the water temperature, the oil temperature and the like of the vehicle on the central control interface. The control data are obtained by collecting the current state and related information of each control on the central control interface.
And acquiring detailed data of all the controls on the current interface through scanning and data extraction of the vehicle-mounted central control system.
And step A30, generating the cache data according to the vehicle state data and the control data, and storing the cache data and the stopping time in a cache unit in an associated manner.
In the embodiment, the cache data consists of vehicle state data and central control data. It is a "snapshot" of the vehicle at its standstill, which completely records the condition of the vehicle and the on-board central control system at this moment. And (5) stopping time, namely accurately recording the time point when the vehicle stops running. The time point is used as an index for associating and identifying the cache data, so that the corresponding cache information can be conveniently and quickly found when the next starting is performed. The buffer unit is a region specially used for storing buffer data in the vehicle-mounted central control system as described above.
And integrating the acquired vehicle state data with control data of the central control current interface to form cache data. This cached data is then stored in the cache unit in association with the current downtime. The storage process needs to ensure the integrity and accuracy of the data and to be stored in an efficient manner so as to be able to be read quickly when required.
Illustratively, the vehicle owner goes home from work, stops the vehicle after parking the vehicle in the garage, and turns off the ignition switch of the vehicle at the moment, so that the vehicle generates a stop command. The control system of the vehicle rapidly starts to collect vehicle state data, the engine speed is reduced to 0, the vehicle speed is 0, the fuel liquid level shows that half of the fuel remains, the battery is full, the four tires are at normal pressure, all doors are closed, the lamplight system is closed except for the small lamps in the vehicle, and the vehicle has no fault code. Meanwhile, the vehicle-mounted central control system plays music, the music playing control data shows that a popular song of a singer is currently played, the playing progress reaches two thirds of the song, the volume is moderate 20, and the playing mode is sequential playing. And when the navigation function is not used, other vehicle information display controls display that the water temperature is normal and the oil temperature is normal. And then, integrating the vehicle state data and control data of the central control current interface by the vehicle-mounted central control system to generate cache data, and storing the cache data in a cache unit in association with the time of stopping the vehicle. Therefore, when the next time the vehicle owner starts the vehicle, if the vehicle-mounted central control system detects the central control preloading instruction, the vehicle-mounted central control system can quickly acquire the cache data according to the stop time, so that more convenient use experience is provided for the user, such as continuously playing songs which are not heard last time, displaying various state information of the vehicle and the like.
The method comprises the steps of obtaining vehicle state data if a vehicle stopping instruction is detected, obtaining control data of a vehicle-mounted central control current interface, generating cache data according to the vehicle state data and the control data, and storing the cache data and stopping time in a cache unit in an associated mode. The data when the vehicle is flameout is used as initial data when the vehicle is started next time, and the using habit of a user is more fitted. Meanwhile, the data is closer to the data when the vehicle is started again, so that the situation that the vehicle data is acquired in full quantity when the vehicle-mounted central control is started is avoided, and the rendering speed of welcome pages is improved.
Based on any one of the above embodiments, a welcome page broadcasting method is provided in a fourth embodiment of the present application, and step S20 includes:
Step S21, determining first display data according to vehicle state data and data abnormality rules in the cache data;
Step S22, determining second display data according to display weights corresponding to control data in the cache data and display content duty ratios corresponding to the first display data;
step S23, determining the control types corresponding to the first display data and the second display data respectively.
In this embodiment, the data anomaly rule is a set of preset judgment criteria for determining whether the vehicle state data exceeds the normal range. These rules are formulated based on design parameters and normal operating ranges of the vehicle. For example, for engine water temperatures, the normal range may be 80-100 degrees celsius, and an anomaly is considered if the water temperature in the buffered data is above 100 degrees celsius or below 80 degrees celsius. For the tire pressure, different standard pressure values are provided for different vehicle types, and marks are generally provided in door frames or vehicle user manuals, and if the actual pressure value and the standard pressure value differ by more than a certain value (such as plus or minus 10%), the tire pressure data is considered to be abnormal. Similarly, the conditions such as sudden and rapid drop of the fuel level, abnormal fluctuation of the battery electric quantity and the like have corresponding judgment rules. The first display data is obtained by checking vehicle state data according to a data abnormality rule, and extracting abnormal data or data which needs to be focused in a specific scene, wherein the abnormal data or the data which needs to be focused in a specific scene form the first display data. For example, if a certain tire pressure of the vehicle is too low, this tire pressure data becomes a part of the first display data because it has an important influence on the running safety of the vehicle, and it is necessary to inform the user in time. By applying the data exception rule to the vehicle state data in the cached data, the system can quickly screen out the first display data and provide basis for subsequent display decisions. Each control data is assigned a display weight that represents the importance of the information represented by the control in the overall display. For example, the navigational controls may be displayed with a higher weight because navigational information is critical to the user during travel, while a particular song information in the music playlist may be weighted relatively low. The display weight is comprehensively determined according to the use habit of the user, the priority of the vehicle function, safety related factors and the like. The display content ratio is the ratio of each data element in the first display data to the whole content to be displayed. For example, if there are three pieces of abnormality data in the first display data, respectively, tire pressure, engine water temperature, battery power, their duty ratio in the display content may be determined according to the degree of abnormality thereof or the magnitude of influence on the vehicle. If the tire pressure is too low, the running safety is influenced to the greatest extent, the ratio of the tire pressure to the running safety is possibly 50%, the abnormal water temperature of the engine is 30%, and the abnormal electric quantity of the battery is 20%. The second display data is combined with the display weight of each control data and the display content ratio of the first display data, and the data to be displayed are further screened and determined. This process takes into account the balance and importance of the overall information. For example, if the navigational control is weighted higher and there are no anomalies in the first display data that seriously affect safety, such as normal tire pressure, normal water temperature, etc., the navigational information may be incorporated into the second display data, but if there are severe vehicle condition anomalies, such as too low tire pressure, the navigational control may preferentially display the tire pressure anomaly information even if the navigational control is weighted higher, where the tire pressure data is an important component of the second display data.
By this way of integrated consideration, the second display data is determined to provide the most valuable information to the user in the limited display space.
As described above, the control types are types of gadgets on the in-vehicle center control display page, and different control types are used to display different types of data. For example, a thermometer-type control for displaying vehicle temperature data is one type, a dashboard for displaying vehicle conditions including information of vehicle speed, rotation speed, and the like is another type, and a warning light-type control for displaying failure warning information is another type. For each data element in the first display data and the second display data, a corresponding control type is determined according to its nature. If the first display data has information of too low tire pressure, the corresponding control type is the tire pressure warning control type, and if the second display data has navigation information, the corresponding control type is the navigation display control type. In this way, it is clear what controls each data should be displayed through on the in-vehicle central control interface, thereby providing accurate guidance for subsequent interface layout and rendering.
Illustratively, the vehicle owner parks after a single vehicle drive, and the vehicle-mounted central control system stores the cache data. When the vehicle state data is analyzed, the engine water temperature is found to be 105 ℃ according to the data abnormality rule, and the right rear tire pressure is 20% lower than the standard value. These abnormal data constitute first display data. In the central control system, the display weight of the navigation control is 30%, the weight of the music playing control is 20%, and the vehicle state display comprises water temperature, oil temperature, tire pressure and other comprehensive information weights of 50%. Since there are an abnormality in the engine water temperature and an abnormality in the tire pressure in the first display data, the abnormality in the engine water temperature accounts for 40% and the abnormality in the tire pressure accounts for 60% of the entire display content. The second display data is determined to include tire pressure abnormality information and engine water temperature abnormality information by comprehensively considering the display weight and the display content duty ratio.
For the first display data and the second display data, the control type corresponding to the abnormal information of the water temperature of the engine is a temperature warning instrument panel control for highlighting the abnormal water temperature, and the control type corresponding to the abnormal information of the tire pressure is a tire pressure warning lamp control. These control types will be used in the display design of subsequent welcome pages or launch interfaces to timely present important information to the user.
Based on any one of the foregoing embodiments, a fifth embodiment of the present application provides a welcome page broadcasting method, and step 30 includes:
Step S31, determining the display size corresponding to the control frame according to the data to be displayed corresponding to each control frame;
step S31, determining the display position and rendering setting data corresponding to each control frame based on each display size and the layer separation rule;
And S31, determining the interface element file according to the display position of each control frame and the rendering setting data.
In this embodiment, the control frames correspond to data to be displayed, each control frame has data to be displayed specifically, and the content, length and other features of the data affect the display size of the control. For example, if the control frame is a control frame that displays song names, the data to be displayed is a long song name, then the control may need to have a larger width to completely display song names, and if the control frame is a control frame that displays vehicle speed, the data to be displayed is only a simple number, such as 60km/h, and the required display size is relatively small. The display size refers to the size occupied by the control on the vehicle-mounted central control screen, and comprises the dimensions of length, width, height and the like. The display size is determined according to the characteristics of the data to be displayed, so that the data can be ensured to be clearly and completely displayed to the user. For some important data or data volume larger, a larger display size may be required for highlighting or full presentation, while for some simple, secondary data smaller display sizes may be used.
And the display size of the data to be displayed corresponding to each control frame is reasonably determined by analyzing the data to be displayed corresponding to each control frame, so that a foundation is provided for subsequent interface layout.
The layer separation rule is a rule for arranging the precedence order of different controls on the display level. Similar to the layering of different elements in graphic design software, some important information or controls that need to be highlighted may be placed at a higher layer, while background class or secondary controls are at a lower layer. For example, alert-type controls such as vehicle fault cues are typically at a higher level so that the user can notice at a first time, while relatively minor information such as a music playlist may be at a lower level. Meanwhile, the layer separation rule also considers the shielding relation among the controls, so that display confusion is avoided. The display position is a specific coordinate position of each control frame on the vehicle-mounted central control screen according to the display size of the control frame and the layer separation rule. This location is determined in consideration of the visual habit and operational convenience of the user, for example, a common control such as a navigation start or pause button may be placed under the screen or in an easily touched area, and important vehicle state information such as vehicle speed, engine water temperature, etc. may be at a conspicuous position in the center or above the screen. The rendering setting data includes parameters related to display effects such as color, transparency, contrast, and the like. For different types of controls, there may be different rendering settings depending on their importance and functionality. For example, alert controls may use a striking red color, a higher contrast, and a lower transparency to highlight abnormal conditions, while normal vehicle information controls may use a common color that coordinates with the background color, with a moderate transparency to preserve the aesthetics and legibility of the interface.
And the display position and rendering setting data of each control frame are accurately determined by comprehensively considering the display size and the layer separation rule so as to optimize the interface layout and the visual effect.
The interface element file is a complete description file of the whole vehicle-mounted central control display interface, and contains the position information, rendering parameters and other contents of all control frames. This document is the basis for subsequent interface rendering, just like a building design drawing, guiding the picture that the central control screen finally presents to the user. The display positions of the control frames and the rendering setting data are integrated together to form an interface element file, so that each control can be displayed in a correct mode at a correct position, and a clear, attractive and reasonable-function vehicle-mounted central control interface is provided for a user.
For example, taking a vehicle start as an example, the cache data includes information such as vehicle speed, engine water temperature, music playing information, vehicle fault prompt and the like. For a control frame displaying the speed of the vehicle, the data to be displayed is a simple numerical range, and a smaller display size is determined according to the characteristics of the data, for example, the width is 1/10 of the width of the screen, and the height is moderate. For a control frame for displaying the water temperature of the engine, the water temperature data needs to be displayed with certain precision, the display size is slightly larger, and the width is 1/8 of the width of the screen. If the song name in the music playing information is longer, the width of the control frame may need to occupy 1/3 of the screen width. The vehicle fault prompting control is large and striking in display size due to the importance of the vehicle fault prompting control, and the width is 1/4 of the width of the screen. According to the layer separation rules, the vehicle fault alert control is at the highest layer, as it is important information that requires immediate attention from the user. The engine water temperature control is at the next highest level, which is the level of the level compared with the highest level, namely the level of the next highest level is lower than the vehicle fault prompting control, but higher than the vehicle speed control, because the water temperature is also critical to the vehicle operation. The vehicle speed control is in the middle layer and the music playing information is in the lower layer. Based on these display sizes and layer rules, a display position is determined. The vehicle fault prompting control is positioned above the center of the screen, the engine water temperature control is positioned on the left side below the vehicle fault prompting control, the vehicle speed control is positioned at the upper right corner of the screen, and the music playing information is positioned below the screen. For rendering setting data, the vehicle fault prompting control adopts red background, white large characters, high contrast and lower transparency such as 70%, the engine water temperature control adopts orange to represent a certain warning meaning, the normal contrast and the transparency, the vehicle speed control adopts green to represent a normal running state, the common transparency, and the music playing information adopts gray coordinated with the background and lower contrast.
And finally, integrating the display positions of the control frames and rendering setting data to form an interface element file for rendering the vehicle-mounted central control screen, and displaying an interface which contains important vehicle information and entertainment information and is reasonable in layout for a user.
Based on any of the above embodiments of the present application, a welcome page broadcasting method is provided in a sixth embodiment of the present application, before step S40, including:
And S41, outputting the model type corresponding to the vehicle type to the display interface of the vehicle-mounted central control.
In this embodiment, the model types corresponding to the vehicle types are three-dimensional model types corresponding to different vehicle types (such as sedan, SUV, MPV, etc.). These model types are created in advance based on the features of the design, the dimensional proportion, and the like of the vehicle. For example, three-dimensional models of cars have smooth lines and low body poses, while SUVs have higher bodies, larger tires, and stiffer lines. When the vehicle is started, the vehicle-mounted central control system outputs the corresponding model type to the display interface according to the type identification information of the vehicle, and the model type is used as a basis for user selection or confirmation.
And the model type corresponding to the vehicle type is presented on a display interface of the vehicle-mounted central control, so that a user can intuitively see the general appearance of the vehicle three-dimensional model to be displayed, and visual reference is provided for subsequent personalized settings.
And step S42, determining a target display type and style parameters according to the touch information received by the display interface.
In the embodiment, the touch information is operation signals such as clicking, sliding, zooming and the like generated by touching the vehicle-mounted central control screen by a user. These touch actions may convey user expectations and preferences for the three-dimensional model display of the vehicle.
The target display type is a specific form of the three-dimensional model of the vehicle to be finally displayed, which is determined based on the touch information of the user. For example, if the user clicks the "sports style" option on the display interface, the target display type may be a sports retrofit three-dimensional model of the vehicle, or if the user selects "interior show," the target display type may focus on a three-dimensional model show of the vehicle interior structure.
Style parameters in addition to determining the target display type, the touch information can also determine style parameters of the model. These parameters include, but are not limited to, color, texture, lighting effects, and the like. For example, the user selects red as the vehicle appearance color by sliding the color selection bar, or adjusts the illumination direction and intensity parameters to create a particular visual atmosphere, the values determined by these operations being the style parameters.
By analyzing touch information of a user on a display interface, the target display type and style parameters are accurately determined, so that the display of the vehicle three-dimensional model can meet the personalized requirements of the user.
And step S43, rendering the vehicle three-dimensional model according to the target display type and the style parameters.
In the embodiment, rendering, namely processing the three-dimensional model of the vehicle according to the target display type and style parameters by utilizing a computer graphics technology, so that the three-dimensional model of the vehicle presents a specific visual effect on a vehicle-mounted central control display interface. This involves combining the geometric shape, surface texture, color, and lighting effects of the three-dimensional model to produce a realistic image. For example, according to the user selected target display type of "vehicle under off-road scene", the rendering process adds off-road tires, luggage racks and other related accessories for the vehicle, and adjusts the texture effects and illumination reflection conditions of soil, water stains and the like of the vehicle in the off-road scene according to style parameters so as to present a complete three-dimensional model picture of the off-road vehicle, which accords with the user's expectations.
Through the steps, firstly, the model type corresponding to the vehicle type is output on the vehicle-mounted central control display interface, clear visual reference is provided for a user, and the understanding and operation guidance of the user to the system are enhanced. And then, determining the target display type and style parameters according to the touch information of the user, so that the personalized requirements of the user are greatly met. The user can select different vehicle display forms and styles according to own preference, so that the three-dimensional model of the vehicle is not a single fixed model, but has high customization. The personalized rendering mode improves the interest and the use frequency of the vehicle-mounted central control system for the user, and the user can experience unique visual perception on the vehicle, and on the other hand, the vehicle display and the information interaction are more visual and rich, so that the vehicle display and the information interaction have better experience no matter the vehicle characteristics are displayed for passengers or the user views the three-dimensional information related to the vehicle state. Moreover, the rendering mode based on user interaction also enables the vehicle-mounted central control system to have more competitive power in the market, can attract more users focusing on personalized experience, and accords with the trend of intelligent and humanized development of modern automobiles.
Based on any of the foregoing embodiments of the present application, a seventh embodiment of the present application provides a welcome page broadcasting method, and step S50 includes:
Step S51, extracting the carefully chosen information corresponding to the cached data based on a preset rule.
In this embodiment, the preset rule is a set of preset screening criteria for selecting information important to the user and required to be presented on the welcome page from the cached data. These rules may be formulated based on priority of information, relevance to the current driving scenario, vehicle safety related factors, and the like. For example, vehicle malfunction information, important reminders such as maintenance expiration reminders, key data of last run such as average fuel consumption too high reminders, etc. may be set as high priority information, while some relatively minor information such as playlist order of last played music is not included in the selected information.
The carefully chosen information is information extracted from the cache data according to a preset rule, and the information is broadcasted to a user in a welcome page, so that the user can quickly acquire important contents. For example, if a sensor of the vehicle fails, the associated fault code and profile may be used as the pick-up information, or if the vehicle is approaching a maintenance mileage, the maintenance reminder may be a part of the pick-up information. And screening the cache data by applying preset rules, extracting carefully chosen information, and providing the most valuable content for users.
And step S52, rendering the welcome page based on the interface element file and the vehicle three-dimensional model alignment based on time sequence, and synchronously broadcasting the carefully selected information.
In this embodiment, the time series alignment is to ensure that the interface element file and the display of the vehicle three-dimensional model remain synchronized and coordinated in time during the rendering of the welcome page. For example, when the welcome page starts to be rendered, the presentation animation of the vehicle three-dimensional model and the appearance order, speed, etc. of the interface elements are to be performed in a predetermined time series. The overall appearance of the three-dimensional model of the vehicle may be displayed first, while some interface elements, such as important vehicle state controls, begin to fade in and then other elements appear in sequence, and during this process, the broadcasting of the selection information is also synchronized with the appearance of these visual elements, and no confusion of visual and audible information can occur. And combining the interface element file and the vehicle three-dimensional model, and generating the visual effect of welcome page by using a graphic rendering technology. The method comprises the steps of drawing each control according to the position, the size and the style in an interface element file, simultaneously displaying a vehicle three-dimensional model on a welcome page in a proper view angle, illumination and animation effect, and enabling all elements to be displayed in a coordinated mode according to the time sequence alignment requirement in the rendering process. And when the welcome page is rendered, using an on-board sound system or other voice broadcasting equipment to play the carefully selected information to the user in a voice mode according to a time sequence alignment mode. For example, when the three-dimensional model of the vehicle is displayed to a certain angle, selected information related to the three-dimensional model of the vehicle is simultaneously broadcast, such as 'the pressure of the left front tire of the vehicle is too low, please check in time', so that a user can receive important information visually and audibly.
Illustratively, after detecting that the vehicle owner has an intention to use, the vehicle-mounted central control system starts to start a welcome page flow. Firstly, the system extracts carefully chosen information from the cache data according to preset rules. The data includes some state information of the vehicle, such as the pressure of each tire, the water temperature of the engine, the average oil consumption of the last running, the maintenance remaining mileage of the vehicle, and the like. According to the preset rule, since the left rear tire pressure is slightly lower than the normal range and the vehicle maintenance mileage remains less than 500 km, these two pieces of information are determined as the selected information. Then, when the welcome page is rendered, the on-board central control system performs time series aligned rendering based on the interface element file and the vehicle three-dimensional model. Welcome page rendering begins with the display of a frontal overview of the vehicle three-dimensional model, while interface elements related to the vehicle appearance, such as a vehicle brand logo, begin to be loaded and displayed. The vehicle three-dimensional model gradually rotates the display side over time, at this time, the control representing the tire pressure displays the left rear tire pressure anomaly in red warning color on the welcome page, and simultaneously voice broadcasts "left rear tire pressure is slightly lower, please keep notice". When the three-dimensional model of the vehicle is displayed on the tail part, the maintenance residual mileage information is highlighted on the interface, and meanwhile, the vehicle maintenance residual mileage is reported by voice to be less than 500 km, and maintenance is reserved in time. In the whole process, the normal information of the engine water temperature is not broadcasted as carefully selected information, and the cache data related to music playing is not displayed or broadcasted on welcome pages, because the importance of the information is lower in the current scene.
Through the refined welcome page rendering and carefully chosen information broadcasting modes, user experience can be remarkably improved. From the information acquisition perspective, the user can learn important vehicle information through voice broadcasting at the first time, and the user does not need to manually search, so that the operation cost and the possibility of distracted driving are reduced. Meanwhile, visual display and voice broadcasting are synchronous, and the multi-sense information processing capability of human beings is utilized, so that information is conveyed more efficiently and deeply. In the aspect of rendering welcome pages, the time sequence alignment mode enables the whole display process to be smoother and more natural, and abrupt display or confusion of information can not occur. The design enhances the functionality and the intelligent degree of the vehicle-mounted central control system, so that the vehicle is not only a vehicle, but also an intelligent terminal capable of actively transmitting key information to a user, and the satisfaction degree and the trust degree of the user on the vehicle system are improved. In addition, the scheme optimization aiming at single vehicle-mounted central control can fully utilize limited hardware resources, avoid information overload, ensure that only the most core and useful content is provided for users in welcome page display links, and accord with the principle of simple and efficient information interaction in vehicle-mounted environments.
Based on any of the above embodiments of the present application, referring to fig. 3, an eighth embodiment of the present application provides a welcome page broadcasting method, and step S50 further includes:
and step S53, extracting the carefully selected information corresponding to the cache data according to a preset rule.
In this embodiment, the preset rule is a set of predetermined screening criteria in the case of multiple vehicle central control, but functions of different display modules and habits of users viewing information at different positions may be considered more carefully. For example, for a primary display module in a primary driving location, information directly related to driving safety such as vehicle failure information, critical vehicle status data priority is higher, while for a secondary display module in a secondary or rear passenger location, some entertainment related or comfort related information such as multimedia play list, seat heating status is also included in the category of choice information. These rules take into account the overall operation of the vehicle and the needs of the different user roles. The carefully selected information is information extracted from the cache data according to the preset rules, and the information is displayed or broadcasted to personnel in the vehicle in a proper mode on different display modules. For example, the selection information of the main display module may include an engine failure code, a brake system status, etc., and the selection information of the auxiliary display module may have a next track on which music is being played, a rear seat massage function status, etc. By extracting the carefully selected information in this way, the content displayed by each display module can be ensured to have a targeted value for the user at the corresponding position.
Step S54, splitting the interface element file based on the assembly position of each secondary display module, so as to determine the display file of each secondary display module.
In the present embodiment, the mounting position of the sub display module is a position where the sub display module is mounted in the vehicle interior, and the function and the facing user group are also different. For example, the secondary display module in front of the co-driver is mainly used for serving the co-driver and the secondary display module in the center of the rear row or at the headrest is designed for the rear-row passengers. The assembly position determines the emphasis of the information that each secondary display module needs to display. Interface element file, which is a file containing layout and style information of all display elements of welcome page, such as various controls, images, text, etc., for guiding the rendering of the whole welcome page. The display file is a specific file split from the interface element file for each sub display module, and defines the content, layout, and style to be displayed by the sub display module. And extracting elements related to the interface element files from the interface element files according to the assembly positions of the auxiliary display modules to form display files of the auxiliary display modules. For example, for the auxiliary display module in front of the co-driver, the display file may include control information related to multimedia control, welcome of some personalized decorative elements for passengers of the co-driver, and the display file of the rear auxiliary display module may have related contents such as rear entertainment system control and seat adjustment function display.
And step S55, based on the interface element file and the vehicle three-dimensional model, based on time sequence alignment, rendering a first welcome page of the main display module, and synchronously broadcasting the carefully selected information.
In this embodiment, the time sequence alignment is more critical in a multi-vehicle central control environment. This requires that the main display module, when rendering the welcome page, be strictly synchronized with the presentation of the selected information, the animated presentation of its vehicle three-dimensional model, the order of appearance and the points in time of the interface elements. For example, when the three-dimensional model of the vehicle rotates to the head view, the state control related to the engine is displayed on the interface and key data of the engine such as water temperature, oil pressure and the like are broadcasted as carefully selected information, so that the main driver can efficiently and orderly acquire the most important driving related information when starting the vehicle. The first welcome page of the primary display module is a welcome page presented to the primary driver by the primary display module. The interface element files and the vehicle three-dimensional model are combined to render according to a time sequence alignment mode, so that a concise, visual and highlighted welcome interface is provided for a driver, and meanwhile, the selected information is broadcasted through voice, so that the driving safety and the timeliness of information acquisition are ensured.
And step S56, rendering a second welcome page of each auxiliary display module based on the display file.
In this embodiment, the second welcome page of the secondary display modules is a welcome page rendered by each secondary display module according to its respective display file. These welcome pages provide personalized information presentation and interactive interfaces for co-and rear passengers. For example, a secondary welcome page of a co-pilot may be presented with entertainment functions and a secondary welcome page of a rear row may focus on seat adjustment and control presentation of a rear entertainment system to provide passengers in different locations with an experience that meets their needs.
Illustratively, a main display module is provided in the vehicle at a center console in front of the main drive, two secondary display modules, one in front of the secondary drive and one at the rear row headrest. When the vehicle owner gets on the vehicle to start the vehicle, the system extracts carefully chosen information according to preset rules. For the main display module, a slight trouble code of the engine, current vehicle speed sensor data, brake system normal information and the like are extracted from the cache data as carefully selected information, because the information is critical to the main driving safety. For the auxiliary display module in front of the copilot, the carefully chosen information comprises a play list for playing music last time, particularly music frequently heard by the copilot passengers and the heating state of the copilot seat, and the carefully chosen information of the auxiliary display module at the back row headrest is the massaging function state of the back row seat and the video information played last time by a back row entertainment system. And then, splitting the interface element file according to the assembly positions of the auxiliary display modules at the front and rear row of the headrest. For the auxiliary display module in front of the auxiliary driver, the display files comprise music play list control, seat heating control display control, personalized animation elements welcome to passengers of the auxiliary driver and the like, and the display files of the auxiliary display module at the back row headrest are provided with back row seat massage function control display, video play list control and the like. The main display module then renders a first welcome page based on the interface element file and the vehicle three-dimensional model for time series alignment. The three-dimensional model of the vehicle firstly displays the whole appearance, simultaneously reports that the vehicle is started and the brake system is normal, when the model rotates to the engine position, displays an engine state control and reports that the engine detects a slight fault code, please pay attention to the light fault code, and meanwhile, the data of the vehicle speed sensor are displayed at a proper position.
