Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Referring to fig. 2 or fig. 3, an embodiment of the present invention provides a method for pushing warning information of V2X, including:
acquiring and analyzing a V2X signal to obtain V2X early warning information;
acquiring and analyzing driver image information, and judging the driving state of a driver;
selecting a corresponding pushing strategy according to the V2X early warning information and the driving state of the driver;
and calling the HMI human-computer interaction equipment according to a pushing strategy, and pushing the V2X early warning information to the driver.
By acquiring the V2X early warning information and the driving state of a driver, the V2X vehicle-road-human cooperation technology is organically combined with the intelligent cabin multi-mode interaction technology, a corresponding pushing strategy is comprehensively selected, HMI (human machine interface) human-computer interaction equipment is called according to the pushing strategy, the V2X early warning information is pushed to the driver, unnecessary early warning prompts are reduced, the driving burden of the driver is relieved, and the driving safety is improved.
In a specific implementation process, referring to fig. 3, the method for obtaining and analyzing the V2X signal to obtain the V2X warning information includes:
receiving an external V2X signal in real time through an antenna;
and calling the OBU to analyze the V2X signal, and identifying to obtain V2X early warning information.
C-V2X (Cellular Vehicle-to-event) is based on the evolved V2X technology of Cellular networks, which is a 3GPP global standard, including LTE-V2X and 5G-V2X. The LTE-V2X provides basic traffic safety early warning for the Internet of vehicles, and the 5G-V2X mainly paves the road for future automatic driving. C-V2X communication is largely divided into three major categories: V2V (Vehicle to Vehicle), V2I (Vehicle to Infrastructure) and V2P (Vehicle to human) form the basis of the V2X Vehicle-road-human synergy. FIG. 3 shows a schematic diagram of "vehicle-road-person" collaboration of V2X, with two-way communication between vehicle and vehicle (V2V), vehicle and infrastructure (V2I); the car and the person (V2P) are used for the car to unidirectionally sense the dynamic of the person through a Road Side Unit (RSU) without carrying any equipment by the person. By realizing information exchange between vehicles and between road surface information and the vehicles, the V2X can provide various external early warning information for drivers, and the information is transmitted to the drivers in the forms of sound, light, electricity, vibration and the like through HMI human machine interaction equipment in the vehicles, so that the driving safety of the drivers is improved. The vehicle's IVI system may initiate real-time V2X signal monitoring, receiving external V2X signals in real-time via an antenna. The vehicle-mounted terminal OBU of the V2X identifies and analyzes V2X information received by the IVI system through an antenna, judges whether V2X early warning information exists in the V2X information, namely whether early warning is formed, if the early warning is not formed, monitoring and analyzing the V2X information is continued, and if the early warning is formed, the V2X early warning information is fed back to the IVI system. From the basic perspective of traffic safety warning, table 1 shows 15 specific V2X warning scenarios. According to the difference of the early warning information, the application scenes are classified into three types in the invention, namely: collision early warning, vehicle speed suggestion and environment prompt.
TABLE 1V 2X early warning scenario
Referring to fig. 2, the method for acquiring and analyzing the image information of the driver and determining the driving state of the driver includes:
acquiring image information of a driver in real time through a camera;
and calling the vehicle-mounted DMS to analyze the image information of the driver, and judging the driving state of the driver in real time.
It should be clear to those skilled in the art that a Driver Monitoring System (DMS) (driver Monitor system) can be used to sense the status of the driver in the cockpit, and an IVI system of the vehicle can initiate real-time DMS status monitoring, and acquire image information of the driver in real time through a camera. In particular, visual non-invasive DMS techniques can be used to study the driver's mind and body conditions in real time by processing the driver's facial images, such as detecting driver status from eyelid closure, blink frequency, gaze direction, yawning, and head movement. The vehicle-mounted DMS system identifies and analyzes the state information required by the DMS, such as the driver image information acquired by the IVI system through the camera, judges whether the driver is in a state influencing driving safety, such as fatigue, distraction, low emotion and the like according to the driver image information, continuously monitors and analyzes the driver image information if the driver is not in the state influencing the driving safety, and feeds back the driving state of the driver to the IVI system if the driver is in the state influencing the driving safety. By combining a multi-mode interaction mode, particularly by a vision-based non-invasive DMS technology, the driving state of a driver is judged, and a corresponding pushing strategy of early warning information is selected through data fusion, so that unnecessary V2X early warning triggering can be effectively inhibited, and the driver is reduced in energy dispersion.
The embodiment of the invention provides a method for pushing V2X early warning information, wherein the method for selecting a corresponding pushing strategy according to V2X early warning information and a driving state of a driver comprises the following steps:
dividing the V2X early warning information into multiple early warning categories according to the early warning scene;
dividing the driving state of a driver into a plurality of driving state categories according to the driving danger level;
creating a push strategy list and storing the push strategy list in a database, wherein the push strategy list is used for defining push strategies corresponding to different early warning categories, namely driver driving state categories;
and selecting a corresponding push strategy from the push strategy list by using a table look-up method according to the V2X early warning information and the driving state of the driver.
Based on the above collaborative analysis and judgment, diversified V2X early warning push strategies are made, that is, the same early warning information can be pushed to the driver in a man-machine interaction manner with different strategies. Under the condition that a driver does not need to interact with the vehicle system actively, the vehicle system can actively adjust the interaction mode with the driver according to the perception judgment of the vehicle system, gradually finish the upgrade iteration of the interaction mode from the current 'driver active interaction' to 'intelligent vehicle active interaction', reduce the driver energy dispersion to the maximum extent and improve the passenger interaction experience. Table 2 shows a push strategy list of warning messages, and the data portion of the whole list is a two-dimensional matrix of 4X 3. Each row represents various pre-warning information push strategies corresponding to the same type of V2X pre-warning categories; each column represents what actions the human-computer interaction device can take under the same type of driving state of the driver. Through the overlapped search of rows and columns, the pushing strategy of the early warning information corresponding to different V2X early warning categories-driver driving state categories can be obtained. It should be noted that the push strategy of the warning information in the table is only an example for explaining the working principle of the method.
TABLE 2 push strategy List of early warning information
On the basis, the method for selecting the corresponding push strategy from the push strategy list by using the table look-up method according to the V2X early warning information and the driving state of the driver comprises the following steps:
judging the early warning type of the V2X early warning information;
searching all push strategies corresponding to the early warning categories in a preset push strategy list;
judging the driving state category of the driver to which the driving state received in real time belongs, and searching a pushing strategy corresponding to the driving state category of the driver in all pushing strategies corresponding to the early warning category.
The types of the V2X early warning information comprise a collision early warning type, a vehicle speed suggestion type, an environment prompt type, an undefined type and the like, wherein when the V2X early warning information does not belong to any one of the collision early warning type, the vehicle speed suggestion type and the environment prompt type, a push strategy corresponding to the undefined type is searched in a preset push strategy list. The driver driving state category comprises a driver non-abnormal state, a driver distraction state, a driver fatigue state and the like. The pushing strategy comprises the steps of not pushing the early warning information, utilizing one or more of voice broadcasting, early warning prompt tone, steering wheel vibration, center control screen popup frame display, digital instrument panel highlight flash and the like to push the early warning information.
Fig. 4 shows in flowchart form the processing of the warning information of the vehicle speed advice class V2X. And when the V2X out-of-control early warning information of the nearby vehicle is received, finding the pushing strategy of the corresponding early warning information of the large category according to classification retrieval. And then further selecting a pushing strategy according to the real-time driving state of the driver, if no abnormity is found, pushing the early warning information by the pushing strategy of the early warning information under the abnormal state, namely playing a message prompt tone through the HMI human-computer interaction equipment, and simultaneously displaying the early warning content in the center control screen in a form of a popup frame. When the driver is found to be in the distraction driving state as a result of monitoring, prompt voice broadcast is reminded, and intermittent beep sound is favorable to drawing the driver back to the normal driving state from the distraction state. For fatigue driving, generally speaking, the reaction speed is slower than that of distraction driving, the warning sound is properly prolonged, the driver can receive the warning, and the distraction is inevitably caused by the fatigue driving, so when the DMS system detects that the driver is in distraction and fatigue states at the same time, the comprehensive decision system determines the HMI man-machine interaction strategy according to the fatigue states.
Fig. 5 shows the processing of the collision warning type V2X warning information in the form of a flowchart. When the forward collision early warning information of V2X of nearby vehicles is received, the pushing strategy of the corresponding early warning information of the large category is found according to classification retrieval, then the real-time driving state of the driver is judged, and the pushing strategy is further selected. If the driver is not tired and distracted when driving, the driver is in a more alert driving state at the moment and has normal reaction capability, and a lighter early warning mode is enough to be alert. Even if no early warning is obtained, the driver in the state can basically well control the vehicle to avoid danger. Under the condition, the short-distance and short-time warning similar to collision early warning is negligible, namely, the HMI equipment is not triggered to alarm, the disturbance to the driver is reduced, the driver is attentive to driving, and perhaps a better pushing scheme is provided. However, if the driver is in a distracted or tired state, the early warning mode is enhanced to a proper extent, which is beneficial to the driver to recover the initiative for the situation control to the maximum extent. Short beeps, repeated flashing of warning signs on the dashboard, and even vibration of the steering wheel are good choices. In specific implementation, for the short-time and urgent warning of collision early warning, whether the abnormal driving state of the driver is fatigue or distraction can be no longer subdivided, and only the abnormal state and the abnormal state can be distinguished.
The embodiment of the invention provides a method for pushing V2X early warning information, which comprises the steps of acquiring V2X early warning information and a driving state of a driver, organically combining a V2X vehicle-road-human cooperation technology with an intelligent cabin multimode interaction technology, comprehensively selecting a corresponding pushing strategy, calling HMI (human machine interface) human-computer interaction equipment according to the pushing strategy, and pushing the V2X early warning information to the driver, so that unnecessary early warning prompts are reduced, the driving burden of the driver is relieved, and the driving safety is improved.

Referring to fig. 7, the policy selection module includes a V2X warning information input unit, a driver driving state input unit, a first search unit, a second search unit, a policy output unit, and a policy database for storing a push policy list of warning information. After the early warning information input unit of the V2X receives the data of the early warning information of the V2X, the first retrieval unit retrieves all corresponding push strategies from a push strategy list of the database according to the early warning information of the V2X and outputs the push strategies to the second retrieval unit, the second retrieval unit further retrieves specific push strategies from the push strategy list of the database according to the driving state of the driver received by the driving state input unit of the driver, combines the retrieval result of the first retrieval unit, outputs the result to the early warning module through the strategy output unit, and outputs the early warning information of the V2X received by the input unit to the early warning module through the strategy output unit. The early warning module controls HMI human-computer interaction equipment in the IVI system according to a pushing strategy, and early warning information of V2X is presented to a driver, so that early warning is formed. In essence, the collaborative decision in this process is the decision on which HMI man-machine interaction to present the warning, and the content of the V2X warning information itself is not changed.
