Description

Technical Field

[0001] This invention relates to the field of vehicle control technology, and in particular to a vehicle fault warning method, device, electronic equipment, and computer program product. Background Technology

[0002] With the rapid development of the automotive industry, especially the popularization of new energy vehicles, vehicle safety features are constantly being upgraded. However, safety hazards during vehicle driving and parking still cannot be ignored. Among them, internal vehicle malfunctions (such as battery overheating, brake failure, and high-voltage system abnormalities) are often difficult for pedestrians and surrounding vehicles to detect in time, which can easily lead to collisions, secondary accidents, and other safety risks.

[0003] In existing technologies, vehicle warning devices are mostly based on in-vehicle warnings (such as dashboard lights and buzzers) or traditional horns. Traditional horns can only emit a fixed frequency horn sound, which cannot convey specific fault information, and their use is limited in urban areas where horns are prohibited. Although some new energy vehicles are equipped with external speakers to meet the requirements for low-speed warning sounds, their functions are limited, and they mostly use preset fixed sound effects. They cannot generate targeted voice warning information based on the real-time fault type of the vehicle, and it is also difficult to achieve automatic linkage between fault detection and warning broadcast. As a result, external personnel and surrounding vehicles cannot quickly and accurately obtain information about potential vehicle hazards, resulting in low efficiency in emergency response.

[0004] Therefore, there is an urgent need for a vehicle fault warning solution that can automatically trigger and accurately transmit fault information based on the real-time fault status of the vehicle. Summary of the Invention

[0005] The purpose of this invention is to at least partially solve one of the technical problems existing in the prior art.

[0006] Therefore, one objective of this invention is to provide a vehicle fault warning method. This method matches warning content with the real-time identified fault type and severity of the current vehicle and generates a dynamic electronic fence, thereby broadcasting the warning content to target vehicles within the dynamic electronic fence. This achieves real-time and accurate transmission of vehicle fault information, enabling target vehicles to take timely avoidance measures and improving vehicle driving safety. In addition, by broadcasting the warning content through the vehicle's external loudspeaker, pedestrians in the vicinity can also be informed of the vehicle's fault status in a timely manner and take avoidance measures, ensuring pedestrian safety.

[0007] Another objective of this invention is to provide a vehicle malfunction warning device.

[0008] To achieve the above-mentioned technical objectives, the technical solutions adopted in the embodiments of the present invention include: On one hand, embodiments of the present invention provide a vehicle fault warning method, including the following steps: Obtain the real-time operating parameters of the current vehicle, and identify the fault type and severity of the current vehicle based on the real-time operating parameters; Based on the fault type and the fault severity, the corresponding warning content is obtained by matching it with a preset warning template library; The target warning distance is determined based on the severity of the fault, and a dynamic electronic fence is generated based on the target warning distance; The warning message is broadcast from the current vehicle to the target vehicle within the dynamic electronic fence, so that the warning message is broadcast inside the target vehicle.

[0012] Furthermore, in one embodiment of the present invention, the step of broadcasting the warning content from the current vehicle to a target vehicle within the dynamic electronic fence, so that the target vehicle broadcasts the warning content inside its vehicle, specifically includes: Obtain the vehicle locations of surrounding vehicles of the current vehicle, and select the surrounding vehicles whose locations are within the dynamic fence as the target vehicle; The current location and the warning message are broadcast to the target vehicle from the current vehicle. The target vehicle determines the location of the faulty vehicle based on its current location, generates target reminder content based on the location of the faulty vehicle and the warning content, and then broadcasts the target reminder content.

[0013] Furthermore, in one embodiment of the present invention, the vehicle fault warning method further includes the following steps: The broadcast frequency and volume are determined based on the severity of the fault, and the warning content is played through an external speaker installed on the current vehicle according to the broadcast frequency and the broadcast volume.

[0027] Reference Figure 1 This invention provides a vehicle fault warning method, which specifically includes the following steps: S101. Obtain the real-time operating parameters of the current vehicle, and identify the fault type and severity of the current vehicle based on the real-time operating parameters; S102. Match the corresponding warning content from the preset warning template library according to the fault type and severity. S103. Determine the target warning distance based on the severity of the fault, and generate a dynamic electronic fence based on the target warning distance; S104. Broadcast warning messages from the current vehicle to the target vehicle within the dynamic electronic fence, so that the warning messages are broadcast inside the target vehicle.

[0028] This invention, in its embodiments, matches warning content with the real-time identified fault type and severity of the current vehicle and generates a dynamic electronic fence. This warning content is then broadcast to target vehicles within the dynamic electronic fence, achieving real-time and accurate transmission of vehicle fault information. This allows target vehicles to take timely evasive action, improving vehicle safety. Furthermore, by broadcasting the warning content through the vehicle's external speakers, nearby pedestrians are also informed of the vehicle's fault status and can take evasive action, ensuring pedestrian safety.

[0029] As a further optional implementation, the real-time operating parameters of the current vehicle are obtained, and the fault type and severity of the current vehicle are identified based on the real-time operating parameters. Specifically, this includes: S1011. Obtain the current operating parameters of the vehicle's powertrain, chassis, and electronic systems. S1012. Input the power system operating parameters, chassis system operating parameters and electronic system operating parameters into the pre-trained vehicle fault diagnosis model to obtain the fault type and fault severity. or, S1013. The operating parameters of the power system, chassis system, and electronic system are compared with the corresponding parameter safety thresholds to obtain several abnormal operating parameters. Based on the abnormal operating parameters, a preset fault mapping table is queried to obtain the fault type and fault severity.

[0030] Specifically, the vehicle's core system operating parameters are collected in real time through the vehicle controller area network (CAN) bus and various sensors, covering power system operating parameters (speed, torque, oil temperature), chassis system operating parameters (brake pressure, tire pressure, steering angle), and electronic system operating parameters (battery voltage, sensor signals, communication bus status).

[0031] There are two implementation methods for identifying fault types and severity: one is through training a vehicle fault diagnosis model, and the other is through setting parameter safety thresholds and a fault mapping table. The vehicle fault diagnosis model can be trained based on a neural network model using multiple pre-collected vehicle operating parameter samples and calibrated fault labels, which will not be elaborated here.

[0032] In another implementation, the collected operating parameters are compared with preset safety thresholds to obtain several abnormal operating parameters of the vehicle. Then, based on these abnormal operating parameters, a fault mapping table is consulted to determine the fault type and severity. The fault mapping table records the fault type and severity corresponding to different combinations of abnormal operating parameters and can be pre-calibrated experimentally. Fault severity can include Level 1 emergency faults (e.g., battery temperature ≥60℃, brake pressure sudden drop of more than 30%), Level 2 warning faults (e.g., battery voltage fluctuation ±10%, high-voltage circuit insulation resistance decrease but protection is not triggered), and Level 3 indication faults (e.g., abnormal battery balancing, excessive brake pad wear).

[0033] Based on the fault type and severity, the system matches corresponding warning content from a pre-set warning template library. This library contains standardized warning templates that correspond one-to-one with different fault types and severity levels, and also supports user-added custom templates. For example, the matched warning content could be "Vehicle brake failure, please avoid it immediately" or "Vehicle battery imbalance abnormality, please maintain a safe distance."

[0034] As a further optional implementation, the target warning distance is determined based on the severity of the fault, and a dynamic electronic fence is generated based on the target warning distance, specifically including: S1031. Determine the current vehicle speed, current position, and current driving scenario; S1032. Determine the target warning distance based on the severity of the fault and the current vehicle speed, and determine the shape of the fence based on the current driving scenario; S1033. Determine the outline of the electronic fence based on the target warning distance and the shape of the fence, and generate a dynamic electronic fence based on the current location and the outline of the electronic fence.

[0035] As an optional implementation, when the current driving scenario is an urban road scenario, the fence shape is rectangular, the electronic fence outline is rectangular, the dynamic electronic fence is a rectangular fence, the length of the rectangular fence is the target warning distance, the width of the rectangular fence is the current road width, and the center of the rectangular fence is the current position. When the current driving scenario is a highway scenario, the fence shape is fan-shaped, the electronic fence outline is a double fan-shaped outline, and the dynamic electronic fence includes a symmetrically set front fan-shaped fence and a rear fan-shaped fence. The radius of the front fan-shaped fence and the rear fan-shaped fence are both the target warning distance, the center of the front fan-shaped fence and the rear fan-shaped fence are both the current position, and the center line of the front fan-shaped fence and the rear fan-shaped fence coincides with the current driving direction of the current vehicle. When the current driving scenario is a rural road scenario, the fence shape is circular, the electronic fence outline is circular, the dynamic electronic fence is a circular fence, the radius of the circular fence is the target warning distance, and the center of the circular fence is the current position.

[0036] Specifically, embodiments of the present invention have designed dynamic electronic fences of different shapes based on different current driving scenarios to adapt to the warning range requirements under different driving scenarios.

[0037] 1. Urban road scenario: Rectangular electronic fence Urban roads have dense traffic and fixed road widths, so rectangular fences can accurately cover the warning range of lanes traveling in the same direction.

[0038] Shape parameter calculation: Length: The target warning distance is determined based on the severity of the fault and the current vehicle speed, and this target warning distance is used as the length of the rectangular electronic fence; Width: Take the actual width of the current road. For example, on a six-lane urban main road, the width of the lanes in the same direction is about 12-15 meters.

[0039] Direction: Extends along the tangent of the road, consistent with the direction of vehicle travel.

[0040] Boundary positioning method: Using the road centerline data of a high-precision map, calculate that the two long sides of the rectangular fence are parallel to the road centerline, and determine the center point of the rectangular fence based on the current position of the vehicle.

[0041] Adaptation and optimization: When encountering intersections, the rectangular fence shape is automatically adjusted to avoid intersecting lanes and only cover lanes going straight; the width can be adjusted according to traffic flow, and the fence width is appropriately reduced during peak hours to avoid interfering with too many vehicles.

[0042] 2. Highway scenario: Fan-shaped electronic fence Highways have high vehicle speeds and wide lane spacing, so fan-shaped fences can effectively cover dangerous areas ahead.

[0043] Shape parameter calculation: Radius: The target warning distance is determined based on the severity of the fault and the current vehicle speed, and this target warning distance is used as the radius of the fan-shaped electronic fence; Angle: Usually set to 120°-150°, covering the main driving area in front of and behind the vehicle; Center point: Real-time location coordinates of the faulty vehicle.

[0044] Boundary positioning method: Taking the current position of the vehicle as the center and the straight line of the driving direction as the central axis of the sector, calculate the boundary line coordinates of the sector fence in front of the vehicle and the sector fence behind the vehicle respectively, and generate a double sector electronic fence.

[0045] Adaptation and optimization: When encountering curves, the fan angle and radius are automatically adjusted to fit the curve.

[0046] 3. Rural road scene: circular electronic fence Rural roads have complex conditions and unclear lane markings; circular fences can fully cover the surrounding dangerous areas.

[0047] Shape parameter calculation: Radius: The target warning distance is determined based on the severity of the fault and the current vehicle speed, and this target warning distance is used as the radius of the circular electronic fence; Center point: Real-time location coordinates of the faulty vehicle.

[0048] Boundary positioning method: The boundary coordinates of the circular fence are generated using the parametric equation of a circle. The shape of the circle can be adjusted according to the road width and the surrounding environment, for example, it can be adjusted to an ellipse on a narrow road.

[0049] Adaptation and optimization: When there are obstacles on both sides of the road, the corresponding part of the circular fence is automatically cut off to avoid invalid warnings; the radius can be adjusted according to the surrounding vehicle density, and the fence range can be appropriately increased in densely populated areas.

[0050] As a further optional implementation, the current vehicle broadcasts a warning message to a target vehicle within the dynamic electronic fence, causing the target vehicle to receive the warning message from inside its vehicle. This specifically includes: S1041. Obtain the vehicle locations of surrounding vehicles of the current vehicle, and select the surrounding vehicles whose vehicle locations are within the dynamic fence as the target vehicle. S1042. Broadcast the current location and warning message to the target vehicle using the current vehicle; S1043. Determine the location of the faulty vehicle based on the current location of the target vehicle, generate target reminder content based on the location of the faulty vehicle and the warning content, and then broadcast the target reminder content.

[0051] Specifically, after establishing a dynamic electronic fence, the locations of surrounding vehicles are obtained via V2X. Vehicles within the dynamic fence are selected as target vehicles, and the current location and warning message are broadcast to them. Upon receiving the broadcast from the faulty vehicle, the target vehicle determines the faulty vehicle's location based on its current location and generates a target alert message. For example, if the faulty vehicle is located to the right front and the warning message is "Vehicle has battery imbalance abnormality, please maintain a safe distance," the generated target alert message could be "Vehicle to the right front has battery imbalance abnormality, please maintain a safe distance." After generating the target alert message, it can be broadcast inside the target vehicle via voice or screen display. Different broadcast methods can be selected based on the severity of the fault, which will not be elaborated upon here.

[0052] As an optional implementation, the vehicle malfunction warning method further includes the following steps: S105. Determine the broadcast frequency and volume according to the severity of the fault, and play the warning content through the external speaker installed on the current vehicle according to the broadcast frequency and volume.

[0053] Specifically, while broadcasting warning messages to surrounding vehicles, the vehicle also plays warning messages through its external speakers to alert nearby pedestrians. Specifically, the system automatically triggers the corresponding broadcast mode based on the severity of the fault: Level 1 emergency faults immediately trigger an external speaker broadcast at a frequency of 2-3 times per second, continuing until the fault is resolved or human intervention occurs; Level 2 warning faults trigger a broadcast with a 1-2 second delay, at a frequency of 1 time per second, continuing for 5-10 seconds before switching to intermittent broadcasting; Level 3 alert faults require driver confirmation before broadcasting, or automatically trigger a single broadcast when the vehicle is stationary; during the broadcast, if ambient noise exceeding 85 decibels is detected, the speaker output power is automatically increased by 10-20%.

[0054] As an optional implementation, the vehicle malfunction warning method further includes the following steps: S106. Identify the movement status of pedestrians in the vicinity through the vehicle's onboard camera / radar and determine the collision risk level based on the movement status. S107. Adjust the broadcast frequency and volume according to the collision risk level.

[0055] Specifically, the system collects real-time data on the vehicle's surrounding environment and identifies the movement status of pedestrians in the vicinity. Based on the movement status, it predicts the collision risk level, automatically adjusts the broadcast volume and frequency based on the collision risk level, and simultaneously feeds back the broadcast status to the in-vehicle controller. The broadcast progress and fault details are displayed on the dashboard.

[0056] The method steps of the embodiments of the present invention have been described above. It can be understood that the embodiments of the present invention match warning content with the real-time identified fault type and severity of the current vehicle and generate a dynamic electronic fence, thereby broadcasting the warning content to the target vehicle within the dynamic electronic fence. This achieves real-time and accurate transmission of vehicle fault information, enabling the target vehicle to take timely avoidance measures and improving vehicle driving safety. Furthermore, by broadcasting the warning content through the vehicle's external loudspeaker, pedestrians in the vicinity can also be informed of the vehicle's fault status and take avoidance measures, ensuring pedestrian safety.
