[0023] Example 1

[0024] According to an embodiment of the present invention, an embodiment of a vehicle fault handling method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0025] Figure 1 This is a flowchart of a vehicle fault handling method according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0026] Step S102: In response to receiving a request signal uploaded by at least one component in the vehicle, determine the functional requirements of the vehicle based on the request signal, wherein the functional requirements are used to represent the conditions required for at least one component to perform the corresponding function.

[0027] The aforementioned vehicles may be vehicles with one or more power sources, including but not limited to: pure electric vehicles, hybrid electric vehicles, and fuel cell vehicles.

[0028] The aforementioned components may be components corresponding to the controller contained in the vehicle or components corresponding to various sensors, which can acquire the vehicle's control signals, including but not limited to: gear shift lever controller, accelerator pedal sensor, and brake pedal sensor.

[0029] The aforementioned request signal can be a signal requesting a corresponding function of the vehicle. Functional requirements can be requirements for vehicle display functions or functions that meet the user's driving needs.

[0030] In one optional embodiment, during vehicle operation, the controller, actuators, and sensors in the vehicle control system cooperate with each other to control the vehicle and ensure its normal operation. Components such as the gear shift lever controller, accelerator pedal sensor, and brake pedal sensor in the vehicle send the acquired request signals to the vehicle controller. Upon receiving a request signal uploaded by at least one component in the vehicle, the system determines the vehicle's functional requirements based on the request signal.

[0031] In another optional embodiment, during the vehicle's operation, the vehicle acquires the road conditions around the vehicle and identifies the driver's eye movements, or determines the driver's driving intention based on signals reported by sensors, determines the request signals of the corresponding components of the vehicle controller and actuators based on the driving intention, and then determines the vehicle's current functional requirements based on the request signals.

[0032] Step S104: Determine the vehicle's fault mode based on functional requirements and the vehicle's current state, wherein the fault mode is used to represent a mode in which functional requirements are not met due to a target component failure, and the target component is used to represent a faulty component that occurs in at least one component.

[0033] The aforementioned current state can be the vehicle's current driving state, including but not limited to: accelerating, constant speed, decelerating, and stationary.

[0034] The above-mentioned failure modes can be the modes corresponding to vehicle malfunctions, or the failure modes of the vehicle control system, including but not limited to: vehicle controller failure, other controller failure, sensor failure, actuator failure, and communication failure between the vehicle controller and other controllers.

[0035] The aforementioned target components can be those that cause vehicle malfunctions.

[0036] In one optional embodiment, the current state of the vehicle is acquired. Based on the vehicle's functional requirements and the current state, it is determined whether the vehicle has a fault. If the current state of the vehicle meets the functional requirements, it is determined that the vehicle does not have a fault; if the current state of the vehicle does not meet the functional requirements, it is determined that the vehicle has a fault. Then, the corresponding target component is determined based on the request signal, and it is determined that the vehicle is currently in a fault mode. When a fault occurs, the faulty component will report the fault to the vehicle controller or report an invalid value through relevant signals. The target component is determined based on the fault or invalid value.

[0037] In another optional embodiment, the current state of the vehicle is obtained, and it is determined whether the operating states of the vehicle's current controllers, actuators, sensors, and other components match the current state of the vehicle. If the operating states of the vehicle components match the current state of the vehicle, it is determined that the vehicle is not faulty and is operating normally. If the operating states of the vehicle components do not match the current state of the vehicle, it is determined that the vehicle is faulty, and the operating logs of each component in the vehicle bus are queried to determine the vehicle fault based on the operating logs.

[0038] Step S106: Perform fault handling on the vehicle based on the fault mode and the component type of the target component in order to eliminate the vehicle's fault mode.

[0039] The aforementioned component types can be the types corresponding to various components in the vehicle, including but not limited to: controller type, sensor type, and actuator type.

[0040] The above-mentioned troubleshooting methods can be used to handle vehicle malfunctions.

[0041] In one optional embodiment, the component type of the target component is determined, and the corresponding fault cause is determined based on the different component types. Based on the fault cause, preventative measures can be implemented in the vehicle controller. These preventative measures can be pre-written into a constraint document during the development process, specifying the requirements for the vehicle controller's functionality. Controlling the vehicle according to these preventative measures can effectively and promptly ensure vehicle safety and eliminate vehicle faults. The fault cause of the target component is recorded, and big data is used to obtain corresponding adjustment measures for the target component, adjusting the performance parameters of the target component.

[0042] In another optional embodiment, the component type of the target component is determined. Based on the component type, it is determined whether there are other components in the vehicle controller system that can cooperate to achieve the functional requirements of the target component. If there is a solution to replace the target component, the vehicle control system controls the corresponding other component to replace the target component's operation, stores the cause of the target component's failure, and displays the target component failure on the instrument panel or sends it to the client and technical personnel. If there is no solution to replace the target component, the corresponding fault response operation is obtained, and the vehicle is urgently handled to ensure vehicle safety. The fault response operation can be a pre-set emergency operation according to specific needs, and may include, but is not limited to, function disabling and function degradation.

[0043] For example, when the vehicle is in Drive (D) and the brake pedal is not depressed, the vehicle controller outputs a corresponding torque request based on the driver's input to the accelerator pedal, controlling the output torque of the motor and engine to control vehicle movement. One possible fault mode is that when the vehicle is in Drive and the brake pedal is not depressed, the torque request output by the vehicle controller does not gradually change according to the accelerator pedal input, but instead increases suddenly. Another fault mode is a malfunction of the accelerator pedal sensor, resulting in a sudden change in the signal reported to the vehicle controller. The consequences are more serious, as the vehicle may experience unexpected acceleration, thus requiring high-priority preventative measures. On the one hand, the safety level of the accelerator pedal sensor needs to be strictly controlled, requiring a sufficiently low probability of signal abrupt changes. On the other hand, to prevent unexpected acceleration caused by sudden accelerator pedal signal changes, the slope of the accelerator pedal's rate of change can be limited to avoid large changes in the accelerator pedal opening detected by the vehicle controller within a short period, which could lead to unexpected acceleration.

[0044] Through the above steps, in response to receiving a request signal uploaded by at least one component in the vehicle, the system can determine the vehicle's functional requirements based on the request signal; determine the vehicle's fault mode based on the functional requirements and the vehicle's current state; and perform fault handling based on the fault mode and the component type of the target component to eliminate the vehicle's fault mode. It should be noted that fault handling based on the fault mode and the component type of the target component enables the acquisition of corresponding fault response operations for the target component, timely elimination of vehicle faults, and improvement of fault handling efficiency. This achieves the technical effect of timely elimination of vehicle faults based on the fault mode and the component type of the target component, thereby solving the technical problem of low fault handling efficiency.

[0045] It should be noted that, Figure 2This is a schematic diagram of an optional vehicle control system according to an embodiment of the present invention. The vehicle control system consists of a controller, sensors, actuators, and a vehicle controller. A power battery controller, a motor controller, an engine controller, and a gear shift lever controller are connected to the vehicle controller as controllers. An accelerator pedal sensor and a brake pedal sensor are connected to the vehicle controller as sensors. A clutch solenoid valve is connected to the vehicle controller as an actuator. The motor controller and engine controller output corresponding torque to drive the vehicle; the motor controller and engine controller output corresponding torque according to the request of the vehicle controller; the power battery controller reports the battery output capacity in real time for the vehicle controller to use for power distribution; the gear shift lever controller reports the driver's operation status of the gear shift lever in real time for the vehicle controller to determine the driver's gear selection intention; the accelerator pedal sensor reports the driver's operation status of the accelerator pedal in real time for the vehicle controller to determine the driver's acceleration intention; the brake pedal sensor reports the driver's operation status of the brake pedal in real time for the vehicle controller to determine the driver's braking intention; the clutch solenoid valve opens and closes according to the control commands of the vehicle controller, and the vehicle controller determines the current opening / closing state of the solenoid valve by collecting the voltage / current status of the solenoid valve.

[0046] Optionally, fault handling of the vehicle based on the fault mode and the component type of the target component to eliminate the fault mode of the vehicle includes: in response to the component type of the target component being a controller type, determining whether there is a substitute component to perform the corresponding function of the target component; in response to the absence of a substitute component, performing fault handling of the vehicle using the fault response operation corresponding to the fault mode to eliminate the fault mode of the vehicle; and in response to the presence of a substitute component, using the substitute component to perform the corresponding function of the target component to eliminate the fault mode of the vehicle.

[0047] The controller types mentioned above can be the various major categories of controllers contained in the vehicle, or the types that control the various functional devices of the vehicle.

[0048] The aforementioned replacement parts are components that can replace the faulty target part to perform the function.

[0049] In one optional embodiment, when the target component is a controller, the vehicle controller determines whether there is a substitute component among the components in the vehicle that can perform the function of the target component. If no substitute component exists, the vehicle fault is handled according to the fault response procedure. This may involve disabling the target component or adjusting its operating parameters to ensure it operates at the lowest power, thereby ensuring vehicle safety. Simultaneously, the fault information of the target component can be displayed to the driver via the instrument panel or voice system to prevent the driver from being unable to handle emergencies in a timely manner. If a substitute component exists, the degree of impact of the target component on the vehicle is determined. If the impact is significant, the substitute component is used to perform the function of the target component; if the impact is minor, no action is taken.

[0050] Optionally, fault handling of the vehicle is performed based on the fault mode and the component type of the target component in order to eliminate the fault mode of the vehicle, including: determining the safety level to which the fault mode belongs in response to the component type of the target component being a sensor type; determining the fault response operation corresponding to the fault mode based on the safety level; and performing fault handling of the vehicle using the fault response operation in order to eliminate the fault mode of the vehicle.

[0051] The sensor types mentioned above can refer to the various major categories of sensors included in a vehicle.

[0052] The aforementioned safety levels can be classified according to the degree of sensor safety risk, including but not limited to: first safety level, second safety level, and third safety level.

[0053] In one optional embodiment, when the target component is a sensor, the safety level of the fault mode is determined. The sensor's fault safety level can be set as needed; generally, sensors require a higher safety level to minimize the probability of sensor failure. Different fault handling measures are determined based on the different safety levels. If the safety level is the third safety level (lower), no fault handling is required. If the safety level is the first safety level (higher), fault response actions are obtained, and the vehicle is handled according to these actions to ensure that the vehicle does not compromise safety. Fault-related information is then provided to the driver via the instrument panel or voice system.

[0054] Optionally, fault handling of the vehicle based on the fault mode and the component type of the target component to eliminate the vehicle's fault mode includes: in response to the target component being of the actuator type, controlling the target component to enter a safety mode and determining whether there is an alternative operation to achieve the corresponding function of the target component; in response to the absence of an alternative operation, using the fault response operation corresponding to the fault mode to handle the vehicle's fault mode to eliminate the vehicle's fault mode; and in response to the absence of an alternative operation, using the fault response operation corresponding to the fault mode to handle the vehicle's fault mode to eliminate the vehicle's fault mode.

[0055] The actuator types mentioned above can be any of the major categories of actuators contained in a vehicle.

[0056] The aforementioned safety mode can be a predefined safe operating mode that does not affect the safety of the entire vehicle.

[0057] The aforementioned alternative operations can be alternative operation schemes that can achieve the corresponding functions of the target component.

[0058] In one optional embodiment, when the target component is an actuator, it is first switched to a safety mode to ensure safe driving. Further, it is determined whether there is an alternative operation that can replace the function of the target component. If no alternative operation is available, emergency braking measures must be initiated to prevent accidents during vehicle operation and ensure the safe and timely evacuation of the driver and occupants. If an alternative operation is available, it is used to implement the function of the target component.

[0059] Optionally, the method further includes: determining that the component type of the target component belongs to the controller type in response to the target component being at least one of the following: a power battery controller, a motor controller, an engine controller, and a gear position controller; determining that the component type of the target component belongs to the sensor type in response to the target component being at least one of the following: an accelerator pedal sensor and a brake pedal sensor; and determining that the component type of the target component belongs to the actuator type in response to the target component being a clutch solenoid valve.

[0060] The aforementioned power battery controller can be used to manage and maintain the high-voltage power battery system of electric vehicles. It is primarily responsible for monitoring, protecting, and balancing the charge and discharge states of each individual battery cell to ensure the entire system operates normally and provides stable drive power.

[0061] The aforementioned motor controller is a device used to control electric motors, adjusting parameters such as speed, direction, and torque. It typically consists of a microprocessor or other digital logic chip, controlling the motor's operation by processing power signals.

[0062] The aforementioned engine controller can be an electronic device used to manage and monitor the operation of the internal combustion engine. It collects data from various engine components (such as air flow meters, temperature sensors, oil pressure sensors, etc.) through sensors and makes adjustments based on this data to ensure that the engine operates in optimal condition.

[0063] The aforementioned gear shift controller can be an electronic device used to adjust a vehicle's transmission, changing the relationship between the vehicle speed and engine RPM selected by the driver, either manually or automatically. It helps the driver more easily control the vehicle's acceleration, deceleration, and stability, and improves fuel efficiency.

[0064] The aforementioned accelerator pedal sensor can be a type of sensor used in automotive control systems. It determines the engine's actions by detecting the driver's input to the accelerator pedal. When the driver presses the accelerator, the sensor sends a signal to the engine control module, instructing it to increase engine speed and output more power. This process helps the driver more accurately control the vehicle's performance when rapid acceleration or overtaking is needed, and also improves fuel economy and reduces emissions.

[0065] The aforementioned brake pedal sensor can be a sensor used to detect the driver's braking operation. It is mounted on the brake pedal and can monitor the state of the brake pedal being pressed or released, sending this information to the vehicle control unit. When the brake pedal is detected to be pressed, the control unit sends a signal to the braking system of each wheel, causing the wheels to stop rotating, thereby slowing down or stopping the vehicle.

[0066] The aforementioned clutch solenoid valve can be a component that controls the flow of fluid in a hydraulic system. It consists of an electromagnet and a valve, and the valve is opened and closed by controlling the on / off state of the electromagnet, thereby changing parameters such as the direction, speed, and pressure of fluid flow.

[0067] In one optional embodiment, if the target component is a power battery controller, motor controller, engine controller, or gear position controller, the component type of the target component is determined to be a controller type; if the target component is an accelerator pedal sensor or brake pedal sensor, the component type of the target component is determined to be a sensor type; if the target component is a clutch solenoid valve, the component type of the target component is determined to be an actuator type.

[0068] Optionally, determining the vehicle's fault mode based on functional requirements and the vehicle's current state includes: determining that the vehicle does not have a fault mode in response to the current state meeting the functional requirements; and determining a target component in the vehicle based on the current state and a request signal in response to the current state not meeting the functional requirements, and determining the fault mode based on the target component.

[0069] In one optional embodiment, if the current state meets the vehicle's functional requirements, it is determined that the vehicle does not have a fault mode, and the fault handling process ends. If the current state does not meet the functional requirements, it is determined that the vehicle has a fault. The vehicle controller receives request signals from various components, determines the target component that has a fault based on the current state and the request signals, and further determines the current vehicle fault mode based on the target component.

[0070] Optionally, the method further includes: in response to the target component being multiple components, determining that the fault mode includes multiple sub-fault modes; sorting the multiple sub-fault modes according to the degree of influence of the multiple sub-fault modes on the vehicle to obtain a sorting result; and performing fault processing on the vehicle based on the multiple sub-fault modes and multiple components according to the sorting result, so as to eliminate the multiple sub-fault modes of the vehicle.

[0071] The aforementioned sub-fault modes can be fault modes that are subordinate to the fault mode. Multiple sub-fault modes can be multiple sub-fault modes contained within a fault mode.

[0072] The above sorting results can be the result of sorting multiple sub-fault modes. The numbers can be from small to large to indicate the degree of influence from shallow to severe or from severe to shallow.

[0073] In one optional embodiment, if the target component is multiple components, that is, multiple controllers, actuators or sensors malfunction, multiple sub-fault modes are determined according to the multiple components, the multiple sub-faults are sorted according to the safety hazard level of the target component to the vehicle, the faults with higher safety hazard levels are processed first according to the order, and pre-set safety measures are activated to handle the faults.

[0074] Figure 3 This is a flowchart of an optional vehicle fault handling method according to an embodiment of the present invention, such as... Figure 3 As shown, the steps of this method are as follows:

[0075] Step S301: Obtain request signals from various components of the vehicle and the current status of the vehicle.

[0076] Step S302: Determine if the request signal matches the current state. If yes, proceed to step S304; otherwise, proceed to step S303.

[0077] Step S303: Confirm that the vehicle has no malfunction.

[0078] Step S304: Determine the target component based on the request signal.

[0079] Step S305: Determine the fault level based on the target component.

[0080] Step S306: Obtain the corresponding fault response operation based on the fault level.

[0081] Step S307: Handle the fault according to the fault handling operation until the fault is eliminated.
