[0038] Figure 1 A step flow chart of the multi-V2X scene display strategy based on the HMI system according to the embodiment 1 of the present application is shown.

[0039] Figure 2 A schematic diagram of the multi-V2X scene display system based on the HMI system according to the embodiment 2 of the present application is shown. DETAILED DESCRIPTION

[0040] The application will be described in more detail with reference to the drawings. Although the preferred embodiments of the application are shown in the drawings, it should be understood that the application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the application will be more thorough and complete, and to fully convey the scope of the application to those skilled in the art.

[0041] A multi-V2X scene display strategy based on an HMI system according to the application comprises

[0042] The display interface of the HMI system is divided into at least two warning display areas, and the display dwell time of the warning display area is set, and different warning display areas are used to display different types of dangerous arbitration information.

[0043] When the HMI system receives the dangerous arbitration information output by the V2X scene, the receiving time is recorded, and based on the type of the received dangerous arbitration information and the comparison result of the time between multiple consecutive dangerous arbitration information and the display dwell time, the display is performed according to different display strategies.

[0044] Specifically, the application classifies the dangerous arbitration information output by the V2X scene to the HMI system according to the type of the V2X scene, divides the display area of the display interface of the HMI system according to the classified dangerous arbitration information, and then displays different types of dangerous arbitration information in the corresponding display area, and controls the display time of the dangerous arbitration information in the HMI display interface through the set display dwell time.

[0045] When the HMI system receives a dangerous arbitration information output by the V2X scene, the HMI system first judges the type of the dangerous arbitration information, and then displays it in the corresponding display area of the display interface according to its type, and the display time is the set display dwell time.

[0046] When the HMI system receives multiple dangerous arbitration information output by the V2X scene in a short time, the types of the dangerous arbitration information are judged, and the absolute difference between each other is calculated according to the order of the receiving time of the dangerous arbitration information, and then it is judged whether the absolute difference between each other is greater than the set display dwell time, if it is greater than the set display dwell time, it is displayed one by one according to the order of the receiving time, if it is less than the set display dwell time, different types of dangerous arbitration information are displayed in the corresponding display area according to different display strategies.

[0047] For example, the V2X scene outputs the dangerous arbitration information of the V2V scene, and the HMI system receives it and judges it as V2V dangerous arbitration information, and then displays the warning type, collision time and collision distance of the message in the V2V warning display area in the display interface, and sets the dwell time to 5 seconds, then the message is displayed for 5 seconds and then canceled.

[0048] For example, the HMI system receives three dangerous arbitration information successively in a short time, and the display retention is set to 5 seconds. According to the judgment, the first one is V2V dangerous arbitration information, the second one is V2V dangerous arbitration information, and the third one is V2I dangerous arbitration information;

[0049] When the absolute difference between the receiving time of the first V2V dangerous arbitration information and the second V2V dangerous arbitration information is greater than 5 seconds, and the absolute difference between the receiving time of the second V2V dangerous arbitration information and the third V2I dangerous arbitration information is greater than 5 seconds, display them in the corresponding V2V warning display area and V2I warning display area according to their receiving time respectively;

[0050] When the absolute difference between the receiving time of the first V2V dangerous arbitration information and the second V2V dangerous arbitration information is greater than 5 seconds, and the absolute difference between the receiving time of the second V2V dangerous arbitration information and the third V2I dangerous arbitration information is less than 5 seconds, display the first V2V dangerous arbitration information according to the receiving time first, then display the second V2V dangerous arbitration information according to the receiving time, and display the third V2I dangerous arbitration information according to the receiving time. At this time, the second V2V dangerous arbitration information and the third V2I dangerous arbitration information will be displayed in the corresponding V2V warning display area and V2I warning display area at the same time;

[0051] When the absolute difference between the receiving time of the first V2V dangerous arbitration information and the second V2V dangerous arbitration information is less than 5 seconds, and the absolute difference between the receiving time of the second V2V dangerous arbitration information and the third V2I dangerous arbitration information is greater than 5 seconds, at this time, the first V2V dangerous arbitration information and the second V2V dangerous arbitration information will be displayed in the V2V warning display area according to the order of receiving time. After the display is over, the third V2I dangerous arbitration information is displayed in the V2I warning display area according to the receiving time;

[0052] When the absolute difference between the receiving time of the first V2V dangerous arbitration information and the second V2V dangerous arbitration information is less than 5 seconds, and the absolute difference between the receiving time of the second V2V dangerous arbitration information and the third V2I dangerous arbitration information is less than 5 seconds, but the absolute difference between the receiving time of the first V2V dangerous arbitration information and the third V2I dangerous arbitration information is greater than 5 seconds, at this time, the first V2V dangerous arbitration information and the second V2V dangerous arbitration information will be displayed in the V2V warning display area according to the order of receiving time. After the first V2V dangerous arbitration information disappears, the third V2I dangerous arbitration information is displayed in the V2I warning display area according to the receiving time. At this time, the display interface will display the second V2V dangerous arbitration information and the third V2I dangerous arbitration information at the same time;

[0053] When the absolute difference between the receiving times of the first V2V danger arbitration information and the second V2V danger arbitration information is less than 5 seconds, and the absolute difference between the receiving times of the second V2V danger arbitration information and the third V2I danger arbitration information is less than 5 seconds, and the absolute difference between the receiving times of the first V2V danger arbitration information and the third V2I danger arbitration information is also less than 5 seconds, at this time, the first V2V danger arbitration information and the second V2V danger arbitration information are displayed in the V2V warning display area according to the order of receiving time, and the third V2I danger arbitration information is displayed in the V2I warning display area according to the receiving time, at this time, the display interface displays the first V2V danger arbitration information, the second V2V danger arbitration information and the third V2I danger arbitration information.

[0054] In one example, the danger arbitration information according to the application comprises:

[0055] V2V danger arbitration information for prompting the driver that the car has the danger of scratching, collision and rear-end collision;

[0056] V2I danger arbitration information for warning the driver of traffic rules, traffic accidents and green wave speed guidance.

[0057] Specifically, V2V is the exchange of speed, position and other information between vehicles and other nearby vehicles, and whether there is a collision danger is judged according to the algorithm; on this basis, the vehicle with driving assistance system will take measures such as alarm, braking, steering, etc. to help the driver avoid accidents;

[0058] V2I is the exchange of information between vehicles and infrastructure, which can monitor the road conditions in real time, such as collecting traffic light status, red / green light time and other information, and then optimizing the best route selection for driving.

[0059] In one example, the warning display area according to the application comprises:

[0060] The V2V warning display area is used to display the specific warning type, warning prompt text, collision time and collision distance of the V2V danger arbitration information;

[0061] The V2I warning display area is used to display the specific warning type, signal light phase information, warning icon and warning distance of the V2I danger arbitration information.

[0062] Specifically, the specific warning type of V2V danger arbitration information includes forward collision, lateral collision and rear-end collision, etc.

[0063] The specific warning type of V2I danger arbitration information includes red light running warning, green wave speed guidance and speed camera warning, etc.

[0064] In one example, the V2I early warning display area according to the present application can be divided into a green wave vehicle speed guidance display area and a non-green wave vehicle speed guidance early warning display area;

[0065] When the V2I danger arbitration information is green wave vehicle speed guidance information, the green wave vehicle speed guidance early warning display area is used to display the corresponding signal lamp phase information and the optimal vehicle speed;

[0066] When the V2I danger arbitration information is not green wave vehicle speed guidance information, the non-green wave vehicle speed guidance early warning display area is used to display the corresponding early warning icon and early warning distance.

[0067] Specifically, V2I obtains accurate intersection signal state through real-time data interaction between the vehicle and the road side unit, combines current vehicle position, speed and other state information, and can correspondingly give the optimal green wave guidance vehicle speed in different road section intervals, and displays the accurate intersection signal state and the optimal green wave guidance vehicle speed in the green wave vehicle speed guidance display area of the V2I early warning display area; or obtains red light running early warning information through real-time data interaction between the vehicle and the road side unit, and displays the early warning icon and early warning distance in the non-green wave vehicle speed guidance display area of the V2I early warning display area.

[0068] In one example, different display strategies according to the present application include:

[0069] When the time between multiple continuous danger arbitration information is greater than or equal to the display residence time, according to the category and receiving time of each of the multiple continuous danger arbitration information, the V2V danger arbitration information and the V2I danger arbitration information are displayed in the corresponding V2V early warning display area and V2I early warning display area in the order of receiving time;

[0070] When the time between multiple continuous danger arbitration information is less than the display residence time, according to the category and receiving time of each of the multiple continuous danger arbitration information, the multiple continuous danger arbitration information is displayed in the corresponding early warning display area at the same time within the display residence time;

[0071] When the comparison result of the time between multiple continuous danger arbitration information and the display residence time contains both greater than or equal to the display residence time and less than the display residence time, according to the category and receiving time of each of the multiple continuous danger arbitration information, the display is performed according to the above two strategies.

[0072] Specifically, when the absolute difference of the receiving time between each two of the plurality of continuous dangerous arbitration information is greater than or equal to the display residence time, the V2V dangerous arbitration information is displayed in the V2V early warning display area, and the V2I dangerous arbitration information is displayed in the V2I early warning display area, wherein the green wave vehicle speed guidance information is displayed in the green wave vehicle speed guidance early warning display area of the V2I early warning display area, the non-green wave vehicle speed guidance information is displayed in the non-green wave vehicle speed guidance early warning display area of the V2I early warning display area, and each of the plurality of continuous dangerous arbitration information is displayed in sequence according to the receiving time;

[0073] When the absolute difference of the receiving time between each two of the plurality of continuous dangerous arbitration information is less than the display residence time, there are three cases according to the category of each of the plurality of continuous dangerous arbitration information, all of the dangerous arbitration information is V2V dangerous arbitration information, all of the dangerous arbitration information is V2I dangerous arbitration information, or both V2V dangerous arbitration information and V2I dangerous arbitration information exist, and the plurality of dangerous arbitration information is displayed in the corresponding early warning display area according to the three different cases and the receiving time of each of the plurality of dangerous arbitration information;

[0074] When the absolute difference of the receiving time between each two of the plurality of continuous dangerous arbitration information is greater than or equal to the display residence time and less than the display residence time, the display is performed in combination with the above two strategies.

[0075] For example, the HMI system receives three dangerous arbitration information, the first one is V2V dangerous arbitration information, the second and the third ones are V2I dangerous arbitration information, the display time is set to 5 seconds, the absolute difference of the receiving time between the first dangerous arbitration information and the second dangerous arbitration information is 6 seconds, and the absolute difference of the receiving time between the second dangerous arbitration information and the third dangerous arbitration information is 2 seconds, at this time, the first dangerous arbitration information is displayed in the V2V early warning display area for 5 seconds, the second dangerous arbitration information is displayed in the V2I early warning display area for 5 seconds after 1 second of the display of the first dangerous arbitration information, and the third dangerous arbitration information is displayed in the V2I early warning display area after 2 seconds of the display of the second dangerous arbitration information, and the third dangerous arbitration information is continued to be displayed for 3 seconds after the display of the second dangerous arbitration information is ended.

[0076] In one example, in the present application, when the time between the plurality of continuous dangerous arbitration information is less than the display residence time, and the plurality of continuous dangerous arbitration information is V2V dangerous arbitration information, the specific early warning type, early warning direction and collision time of the plurality of V2V dangerous arbitration information are acquired respectively, the emergency degree of the plurality of V2V dangerous arbitration information is determined according to the order of the collision time of the plurality of V2V dangerous arbitration information, and the early warning direction of the plurality of V2V dangerous arbitration information is displayed in the V2V early warning display area in the form of radar pattern, and the emergency degree of the plurality of V2V dangerous arbitration information is represented by the color of the radar pattern.

[0077] For example, if the HMI system receives 3 dangerous arbitration information within the display dwell time, and all are V2V dangerous arbitration information, the specific warning types, warning directions and collision times of the 3 V2V dangerous arbitration information are front collision after 10 seconds, right side collision after 12 seconds and rear-end collision after 11 seconds, and the emergency degree is front collision > rear-end collision > right side collision, which are displayed in the V2V warning display area in the form of radar patterns, the direction of the radar pattern shows the warning direction, and the color of the radar pattern represents the emergency degree, for example, red represents the first emergency degree of front collision, yellow represents the second emergency degree of rear-end collision, and green represents the third emergency degree of right side collision.

[0078] In one example, in the present application, when the time between multiple continuous dangerous arbitration information is less than the display dwell time, and the multiple continuous dangerous arbitration information are all V2I dangerous arbitration information, the specific warning types of the multiple V2I dangerous arbitration information are acquired respectively.

[0079] When the specific warning type is V2I dangerous arbitration information of green wave speed guidance, the signal lamp phase information thereof is displayed in the V2I warning display area.

[0080] When the specific warning type is not V2I dangerous arbitration information of green wave speed guidance, the warning icon and warning distance thereof are displayed in the V2I warning display area.

[0081] For example, when the HMI system receives two dangerous arbitration information within the display dwell time, and both are V2I dangerous arbitration information, one of which is green wave speed guidance and the other is red light running warning, the signal lamp phase and optimal speed of the warning type of green wave speed guidance are displayed in the green wave speed guidance display area of the V2I warning display area, and the corresponding warning icon and distance information of the warning type of red light running warning are displayed in the green wave speed guidance display area of the V2I warning display area.

[0082] In one example, in the present application, when the time between multiple continuous dangerous arbitration information is less than the display dwell time, and the multiple continuous dangerous arbitration information contain both V2V dangerous arbitration information and V2I dangerous arbitration information, the V2V warning display area and the V2I warning display area are displayed respectively according to the corresponding V2V dangerous arbitration information and V2I dangerous arbitration information.

[0083] For example, when the HMI system receives 3 dangerous arbitration information within the display dwell time, one of which is V2V dangerous arbitration information, and the other two are V2I dangerous arbitration information; the specific warning type of the V2V dangerous arbitration information is forward collision, and one of the specific warning types of the V2I dangerous arbitration information is green wave speed guidance, and the other specific warning type is red light running warning, the warning indication text, collision time and collision distance and other information are displayed in the V2V warning display area, and the other two V2I dangerous arbitration information are displayed in the V2I warning display area, wherein the signal light phase and the optimal vehicle speed of the warning type of the green wave speed guidance are displayed in the green wave speed guidance display area of the V2I warning display area, and the corresponding warning icon and distance information of the warning type of the red light running warning are displayed in the green wave speed guidance display area of the V2I warning display area.
