[0028] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this application, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" may also be interpreted as "when," "when," or "in response to a determination."

[0029] Example 1

[0030] For example, see Figure 1 As shown, Figure 1 This is a schematic diagram of a vehicle auxiliary braking warning system provided in an embodiment of this application. The vehicle auxiliary braking warning system includes: a vehicle diagnostic unit 10, a road condition monitoring unit 11, a signal recognition unit 12, a warning unit 13, and a vehicle motion controller 14.

[0031] The road condition monitoring unit 11 and the signal recognition unit 12 are communicatively connected. The signal recognition unit 12 is also communicatively connected to the vehicle motion controller 14. The signal recognition unit 12 is used to determine road condition information based on the road condition data collected by the road condition monitoring unit 11 and to feed back the determined road condition information to the vehicle motion controller 14. The self-diagnostic unit 10 is communicatively connected to the vehicle motion controller 14 and is electrically connected to the vehicle's power-on system (not shown in the attached figure). It is used to diagnose faults in the vehicle control system when the vehicle is powered on (vehicle starts) and to send the determined diagnostic results to the vehicle motion controller 14. The vehicle motion controller 14 is communicatively connected to the prompting unit 13. The vehicle motion controller 14 generates auxiliary control commands based on one or more of the diagnostic results and road condition information and sends the auxiliary control commands to the prompting unit 13 so that the prompting unit 13 can provide feedback prompts on the received auxiliary control commands. In this embodiment of the application, when the vehicle is powered on, the self-diagnostic unit included in the system performs targeted detection on the vehicle's hardware and software systems to promptly obtain fault information and provide targeted feedback through the prompting unit. This provides timely warnings before the vehicle is driven on the road, thereby better ensuring vehicle safety. In this preferred embodiment, each unit module has a shared or independent power supply system for powering it; this will not be elaborated upon here.

[0032] Optionally, in one implementation of the embodiments of this application, such as Figure 1As shown, the road condition monitoring unit 11 can specifically consist of an onboard camera 111 and an onboard radar 112. Both the onboard camera 111 and the onboard radar 112 are installed on the front side of the vehicle to acquire road condition data in front of the vehicle in a timely manner, such as road congestion information or other obstacle information. Specifically, in a specific implementation scenario of this application embodiment, the number of onboard cameras 111 can be multiple, preferably three, respectively disposed on the upper left front side, right front side, and center front side of the vehicle, for collecting road condition information on the left side, the right side, and directly in front, so that the information recognition unit can determine more accurate road condition data ahead based on the road condition data in the three directions according to a preset image processing algorithm.

[0033] Optionally, in one embodiment of this application, the prompting unit is configured as a vehicle dashboard. The vehicle dashboard has multiple display blocks to provide targeted feedback on the prompting information contained in the auxiliary control commands. In practical application scenarios of this application embodiment, users may encounter various situations requiring emergency braking while driving, such as traffic jams or other obstacles, or a malfunction in the vehicle's control system. To provide timely and accurate feedback on these situations, the prompting unit can be configured as a dashboard with multiple display blocks. Different display blocks can provide targeted feedback for different situations or malfunctions. This approach not only reduces the difficulty of setting up the prompting unit by utilizing a vehicle dashboard and improves the reusability of vehicle hardware resources, thus reducing the implementation difficulty of the system described in this application embodiment, but also meets the user's auxiliary braking prompting needs and improves the user experience.

[0034] Specifically, in one optional implementation of this application embodiment, multiple display blocks are divided in the dashboard into at least a strip signal indicator display area and a vehicle fault display area. Correspondingly, a prompting unit provides feedback prompts on the received auxiliary control commands, including: providing feedback prompts through the vehicle fault display area based on fault feedback instructions included in the auxiliary control commands; and providing feedback prompts through the strip signal indicator based on road condition information or vehicle information ahead included in the auxiliary control commands. This configuration is simpler and provides clearer feedback, making it easier for users to obtain and understand in a timely manner, thereby reducing user effort and improving user satisfaction.

[0035] Optionally, in one embodiment of this application, such as Figure 2 As shown, Figure 2This is a partial structural diagram of an instrument panel provided in an embodiment of this application. One or more indicator lights in the strip-shaped signal indicator lights are arranged in a predetermined order on the vehicle instrument panel. The arrangement corresponds sequentially to the positions of multiple vehicles within a predetermined range ahead in the same direction of travel lane as the vehicle. For example, as shown... Figure 2 As shown, multiple indicator lights 1 to 4 are arranged in an orderly manner in the strip signal indicator display area of ​​the instrument panel, corresponding one-to-one with the detected vehicles ahead. Indicator light 1 provides feedback on the taillight status of the first vehicle in front of the current vehicle, indicator light 2 provides feedback on the taillight status of the second vehicle in front of the current vehicle, and so on. When indicator light 2 is illuminated, it indicates that the taillights of the second vehicle in front of the current vehicle are illuminated, prompting the current vehicle to pay attention to the sudden braking of the vehicle in front. Of course, this application is only illustrating the function of the strip indicator lights in this example and does not mean that the application is limited to this. The illumination method can also be set to other methods. For example, if there is congestion or emergency braking in the current lane, and the fourth vehicle in front begins to brake and illuminates its brake lights, while the brake lights of the third vehicle, the second vehicle, and the first vehicle are not illuminated, then only indicator light 4 on the instrument panel is illuminated to provide feedback and prompt the driver that there may be a road condition requiring braking ahead. If the brake lights of the fourth vehicle in the lead are deactivated, indicator light 4 will illuminate for a 3-second delay before turning off. If the fourth vehicle in the lead begins to brake and activates its brake lights, the brake lights of the third and second vehicles will illuminate sequentially, while the brake lights of the first vehicle will not illuminate. The brake lights will then illuminate sequentially according to the timing of the corresponding vehicle's brake light activation captured by the onboard camera and the auxiliary control command issued by the vehicle motion controller. Figure 2 The indicator lights on the dashboard, numbered 4, 3, and 2, systematically alert the user to potential road conditions requiring braking ahead. If all indicator lights are illuminated, or if indicator lights 3, 2, and 1 are all lit, it indicates that an emergency braking situation is imminent, requiring immediate braking. This embodiment of the application arranges and controls the illumination of the strip indicator lights in this way, providing clearer and more accurate targeted feedback to the user. The feedback results are accurate and reliable, thereby improving the user experience.

[0036] Optionally, in one embodiment of this application, the display mode when the one or more orderly arranged indicator lights are activated includes one or more of the following: sequential light display, constant light display, or flashing display. In the actual application scenarios of this application embodiment, vehicles need to brake frequently. If a corresponding display block or indicator light is configured for each braking warning situation caused by different reasons, the setup process is too complicated, and it is easy for users to have to pay attention to too much indication information, which is not conducive to users clearly determining the reason for braking. Therefore, in this application embodiment, it is limited to configuring corresponding display modes for different braking warning situations. That is, with limited deployment of indicator lights, targeted feedback prompts can be provided through different display modes, reducing the effort consumed by users to understand the feedback prompts and the reasons for braking warnings, and improving the user's reaction speed for emergency braking.

[0037] Optionally, in one embodiment of this application, each display block in the dashboard is an independently controlled display block, and the plurality of display blocks are composed of one or more of the following: multi-light combinations, segment display combinations, or image and icon display combinations. In the implementation of this application embodiment, the independently controlled approach can improve the accuracy of feedback prompts through light illumination and reduce the probability of system malfunction due to partial display block failures. Furthermore, setting these display blocks as multi-light combinations, segment display combinations, or image and icon display combinations makes the feedback prompts richer and more intuitive, providing users with a more visually striking feedback prompt method and reducing the possibility of users neglecting braking warnings.

[0038] Optionally, in one implementation of this application embodiment, the vehicle motion controller is provided with a configuration interface for configuring an auxiliary braking strategy into the vehicle motion controller. Correspondingly, the vehicle motion controller generates an auxiliary control command based on one or more of the acquired diagnostic results and road condition information, including: the vehicle motion controller generates the auxiliary control command based on the configured auxiliary braking strategy and in combination with one or more of the diagnostic results or road condition information. By setting up a configuration interface, operators or users can achieve diverse braking warnings through flexibly configured assigned braking strategies, providing targeted services for different vehicle models or users, and further improving the user experience.

[0039] Optionally, in one embodiment of this application, the auxiliary braking strategy includes at least: when the vehicle motion controller determines the taillight status of other vehicles within a preset range ahead of the vehicle based on the road condition information, controlling the strip signal lights to illuminate accordingly based on the taillight status of the other vehicles; wherein the taillight status includes at least one or more of the following: brake light illumination, high-mounted brake light illumination, reversing light illumination, and emergency braking hazard lights illumination. This approach can further improve the accuracy of the feedback prompts.

[0040] Optionally, in one embodiment of this application, the vehicle motion controller is further configured to acquire the vehicle's speed in real time and calculate the vehicle's braking distance based on the speed; when the vehicle motion controller determines an obstacle ahead based on the road condition information, it acquires the obstacle distance between the vehicle and the obstacle; when it determines that the difference between the braking distance and the obstacle distance is less than a preset value, it generates an auxiliary control command to control the prompting unit to provide feedback. This provides the user with timely and reliable braking warning prompts, improving the user's driving safety.

[0041] Specifically, this application provides an example to illustrate the above content. If there are obstacles or traffic lights prohibiting passage in the current lane, and a pedestrian is detected crossing the lane, or a red light or large rock obstructs the road, a correspondence can be established between the aforementioned strip indicator lights or a combination of images and icons and these detected targets. Braking feedback is then provided by illuminating the combination display block corresponding to these indicator lights or icons. Specifically, taking the four indicator lights in the instrument panel shown in Figure 2 as an example: When the vehicle speed exceeds 90 km / h, and the vehicle camera or radar detects a large rock obstructing the road, a pothole, a red light, or a pedestrian within 60 meters ahead of the vehicle, requiring braking warning, the signal recognition unit processes the collected road condition data, and the vehicle controller generates corresponding auxiliary control commands based on this data, sending signals to the instrument panel to illuminate indicator light 4 for braking feedback. If the vehicle speed is less than or equal to 90 km / h but exceeds 60 km / h, the vehicle camera or radar... If the vehicle-mounted radar detects a large rock obstructing the road, a pothole, a red light, or a pedestrian within 30 meters of the road ahead, it will control the instrument panel to illuminate the brake indicator light 3 as a braking feedback warning. If the vehicle speed is less than or equal to 60 km / h but exceeds 30 km / h, and the vehicle-mounted camera detects a large rock obstructing the road, a pothole, a red light, or a pedestrian within 15 meters of the intersection ahead, it will control the instrument panel to illuminate the brake indicator light 2 as a warning. If the vehicle speed is less than or equal to 30 km / h but exceeds 10 km / h, and the camera detects a large rock obstructing the road, a pothole, a red light, or a pedestrian within 6 meters of the intersection ahead, it will illuminate the brake indicator block 2 as a warning. This embodiment of the application provides users with highly reliable and stable braking feedback warnings through a relatively simple indicator light setting method, offering users practical braking warnings with low implementation costs and a high user experience.

[0042] Optionally, in one embodiment of this application, the feedback prompting method of the prompting unit includes at least controlling the display blocks to be displayed in superimposed form and displaying in time intervals; wherein, the superimposed display refers to superimposing and highlighting multiple display blocks under the control of the auxiliary control command; the time interval display refers to sequentially displaying the multiple display blocks in turn at fixed intervals under the control of the auxiliary control command. For example, if a vehicle is traveling at 100 km / h on a highway, and the vehicle camera and radar detect a large pothole 30 meters ahead, and there are only two vehicles ahead, with the second vehicle's brake light illuminated and the first vehicle's brake light off, if the dashboard has a prompting setting such as... Figure 2The strip-shaped indicator lights shown are used for braking warnings. When the vehicle is moving too fast to detect a large pothole, indicator light 4 on the instrument panel will illuminate. When a vehicle ahead illuminates its taillights to indicate whether braking is necessary, indicator light 2 on the instrument panel will illuminate. This can be achieved by combining an auxiliary braking strategy with a superimposed display, where the instrument panel simultaneously illuminates both indicator lights 4 and 2, or by sequentially illuminating lights 2 and 4 at fixed intervals. This provides users with a comprehensive and accurate braking warning experience.

[0043] Optionally, in a specific implementation of this application embodiment, the communication connection between the various units is achieved through an in-vehicle CAN (Controller Area Network) bus. The CAN bus is a serial data communication bus with a maximum communication rate of 1Mb / s. In this embodiment, by utilizing the CAN bus to support communication, the complexity of the communication wiring harness in the vehicle can be reduced while ensuring good communication speed and accuracy for the entire system.
