Detailed ways

In the following description, for the purpose of illustration rather than limitation, specific details such as a specific system structure and technology are set forth in order to provide a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

In order to make the objectives, technical solutions and advantages of the present application clearer, the following descriptions will be given through specific embodiments in conjunction with the accompanying drawings.

Fig. 1 is the realization flow chart of the starry sky top display method that the embodiment of the present application provides, is described in detail as follows:

Step 101, obtaining navigation information of the vehicle.

In this embodiment, the driver usually starts the navigation software built into the mobile phone or the vehicle, and follows the route provided by the navigation software. At this time, the estimated travel route of the vehicle can be directly obtained from the navigation software as the navigation information.

In another case, if the estimated driving path of the vehicle cannot be obtained in the navigation software, the status information of the vehicle can also be used as the navigation information, such as location information, driving direction, vehicle speed, fuel level in the fuel tank, etc.

In addition, the operation of the driver can also be used as navigation information, such as the rotation of the steering wheel, the gear change of the gear lever, the switch of the turn signal and the brake light, the depressing range of the brake, accelerator, and clutch pedal, etc. It reflects the driving intention of the driver and is used to determine the traveling state of the vehicle after a set period of time.

Step 102 , according to the navigation information, determine the traveling state of the vehicle after the set duration.

In this embodiment of the present application, the traveling state of the vehicle may include left steering, right steering, deceleration, acceleration, or bumping, and the like. According to the navigation information, the traveling state of the vehicle can be predicted in advance. For example, when the driving path indicated by the navigation software contains steering information, it can be predicted in advance that the vehicle will turn after a certain period of time. Combined with the vehicle speed information, it is also possible to know how long it will take for the vehicle to turn. will turn.

One of the purposes of the present application is to enable rear passengers to predict the traveling state of the vehicle in advance, so as to be prepared when the traveling state of the vehicle changes. Therefore, the set duration in the above-mentioned step 102 means the advance prediction time left for the passengers. For example, the set duration is 1 minute, that is, the purpose is to allow the passengers to predict the traveling state of the vehicle after 1 minute in advance, and according to the navigation information combined with the vehicle speed information. It can be obtained whether the vehicle is turning left, turning right, decelerating or accelerating after 1 minute.

In a specific implementation, the navigation information and the state information of some vehicles can also be combined to determine the travel state after the set duration. The state information of the vehicle may be vehicle speed information, fuel tank fuel quantity information, and the like. In this way, the traveling state of the vehicle after the set period of time can be predicted more accurately.

In specific implementation, it is also possible to combine navigation information and state signals related to the driver's operation to comprehensively judge the travel state after the set time period, such as the vehicle's turn signal, gear change signal, etc.; when the vehicle's left turn signal lights up , indicating that the vehicle may turn left after a period of time; when the vehicle's speed gear becomes higher, it indicates that the vehicle may accelerate.

Step 103 , generating a display control instruction according to the traveling state of the vehicle after the set time period, and the display control instruction is used to control the star roof to provide information prompts for the traveling state of the vehicle after the set period of time.

In this embodiment, each traveling state of the vehicle can correspond to a type of display effect of the starry sky, so that the rear passengers can know the traveling state of the vehicle after the set time period when they see the display effect of the starry sky. , the change of the traveling state of the vehicle can be known in advance, so as to be prepared, and avoid affecting the riding comfort or safety due to the inability to understand the traveling state of the vehicle.

In one possible implementation, the travel state includes a left turn;

Correspondingly, controlling the sky top to provide information prompts for the traveling state of the vehicle after the set time period includes:

Controls the star dome to display a preset pattern in the left direction.

In one possible implementation, the travel state includes a right turn;

Correspondingly, controlling the sky top to provide information prompts for the traveling state of the vehicle after the set time period includes:

Controls the starry sky top to display a preset pattern in the right direction.

In this embodiment, the left turn may correspond to a leftward shooting star pattern, a leftward arrow pattern, a leftward flowing water pattern, etc., and a right turn corresponds to each rightward preset pattern. It is also possible to indicate a right turn by changing the color from left to right. The custom pattern uploaded by the user can also be dynamically displayed in the corresponding direction according to the steering direction. For example, if the pattern uploaded by the user is a bear pattern, and the traveling state is turning left, the bear pattern moving from right to left is displayed.

In a possible implementation manner, according to the navigation information, determining the traveling state of the vehicle after the set period of time includes:

Obtain speed limit information based on navigation information;

Obtain the current vehicle speed, and judge whether the vehicle needs to decelerate according to the current vehicle speed and speed limit information;

Correspondingly, if it is determined that the vehicle needs to decelerate, the display control command is specifically used to:

Controls the sky top to display a preset deceleration pattern.

In this embodiment, the next overspeed detection point in the driving path and the speed limit value of the overspeed detection point can be obtained. If the current vehicle speed exceeds the speed limit value, it is determined that the vehicle needs to decelerate, and at the same time, it is determined that the vehicle needs to decelerate after the set time. The travel state is deceleration.

The control terminal can also predict the driver's possible braking force according to the degree to which the current vehicle speed exceeds the speed limit value, that is, the speed at which the vehicle decelerates; for example, when the distance from the speed limit road section is certain, the current vehicle speed exceeds the speed limit road section The magnitude of the value is different, and the driver's possible braking force is different. The greater the current vehicle speed exceeds the speed limit value of the speed limit section, the greater the driver's possible braking force, and the braking deceleration may be more urgent. At this time, the star roof can be controlled to flash at a faster frequency to remind the rear passengers that the vehicle may decelerate urgently, so that the rear passengers can prepare for safety in advance. When the current vehicle speed exceeds the speed limit value of the speed limit road section, the driver may press the brakes with less force, and the braking deceleration may be gentle this time. At this time, the star roof can be controlled to flash at a slower frequency. To remind rear passengers that the vehicle may slow down slowly, so that rear passengers can prepare for safety in advance.

In a possible implementation manner, after acquiring the navigation information of the vehicle, the method further includes:

Obtain speed limit information based on navigation information;

Obtain the current vehicle speed, and judge whether the vehicle is overspeeding according to the current vehicle speed and speed limit information;

If the vehicle is speeding, control the star dome to flash and/or change the display color of the star dome.

In this embodiment, the speed limit information may include a speed limit value, a start point of a speed limit section, and an end point of a speed limit section. After acquiring the speed limit information, the control terminal can first determine the distance between the current position of the vehicle and the starting point of the speed limit road section, and whether the current vehicle speed exceeds the speed limit value of the speed limit road section.

When the current position of the vehicle reaches a certain distance from the starting point of the speed-limited road section, if the current vehicle speed exceeds the speed limit value of the speed-limited road section, it is considered that the vehicle has the risk of overspeeding, and the flashing of the star roof can be controlled, and/or the speed of the star roof can be changed. Display colors to alert rear occupants.

In a further embodiment, the degree of change of the flickering frequency of the starry sky can also be controlled, or the effect of the color change is associated with the degree of the vehicle speeding, for example, the greater the possibility of the vehicle speeding (or the greater the speed limit value is) ), the faster the blinking frequency of the starry sky, or the more obvious the color change of the starry sky. Conversely, when the possibility of the vehicle overspeeding is smaller (or the smaller the speed limit value is), the flickering frequency of the starry sky can be slower, or the display color of the starry sky can change smoothly.

In a possible implementation, controlling the starry sky top flashing includes:

Calculate the flicker frequency based on the preset flicker frequency formula; the flicker frequency formula is:

f=f ₀ (V _current - V _threshold ) K ₁

Among them, f represents the flicker frequency, V _current represents the current vehicle speed, V _threshold represents the speed limit value, K ₁ represents the preset frequency proportional coefficient, and f ₀ represents the preset reference flicker frequency;

Controls the sky top to flash at a flashing frequency.

In this embodiment, the lights when the starry sky is flashing are only used to remind rear passengers and will not affect the driver. If the driver is worried about being affected by the starry sky flashing, the flashing area of the starry sky can also be preset.

Further, you can also change the flashing area on the top of the starry sky to give an overspeed prompt. For example, when it is detected that the vehicle is speeding, the lights in a small area in the sky top will be controlled to flicker first. If the vehicle is still speeding after a period of time, the flashing area will be enlarged to increase the intensity of the prompt.

In a possible implementation, changing the display color of the sky top includes:

Calculate the amount of color component change based on a preset color formula; the color formula is:

_ΔRGB = R ₀ (V _current - V _threshold ) K ₂

Among them, _ΔRGB represents the color component change amount, V _current represents the current vehicle speed, V _threshold represents the speed limit value, K ₂ represents the preset color scale coefficient, and R ₀ represents the color component change amount corresponding to each overspeed preset value;

Subtract the change amount of the color component from the RGB value of the display color of the starry sky roof except the preset alarm color to obtain the color corresponding to the current vehicle speed;

Change the display color of the sky top to the color corresponding to the current speed.

In this embodiment, the format of the RGB value is (R, G, B), where R represents the red component, G represents the green component, and B represents the blue component. The value ranges of the three are [0, 255], and RGB is (255,0,0), the light is red, and when RGB is (255,255,255), the light is white. Users can preset the color used for speeding warning, and the color formula is used to calculate the degree of change in the display color of the sky top. Indicates the speed of the current vehicle speed.

For example, if the user has set the star roof to display red when speeding, and white when not speeding, the control terminal can change the display color of the star roof to the set red when it detects that the vehicle is overspeeding, and continue to monitor the speed of the vehicle. When the vehicle decelerates, the display color of the sky top is controlled to gradually change to white, so that when the vehicle is not speeding, the display color of the sky top just changes to white. In order to realize that the display color of the star roof just changes to white when the vehicle speed reaches no speed limit, the control terminal can adjust the display color of the star roof every period of time, so that the rear passengers can feel that the display color of the star roof is continuous. and changing slowly.

In another case, you can also set the color change amount corresponding to the unit overspeed value. For example, every time the current vehicle speed exceeds the speed limit value by 1km/h, the G value and B value of the display color of the sky top will decrease by 1. When it is high, the display color of the sky top will be closer to red. When the display color of the star roof is red, the display color of the star roof no longer changes with the increase of vehicle speed. In addition, the user can also preset the speed limit value, and change the color change amount of the unit overspeed value by adjusting the color scale factor.
