[0042] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0043] When there are serious problems with the ECU hardware or underlying software that cannot be repaired, a reset operation can be used to repair it. When an electric vehicle fails, the system may perform downgrade actions, such as limiting the vehicle speed, reducing power, etc., to ensure the safe operation of the vehicle. If during the execution of the downgrade action, if the underlying software of the ECU triggers a reset operation due to a software problem, the ECU will restart and return to normal. The reset operation may clear some or all of the data in the ECU, including diagnostic information related to the fault. Due to the clearing of data, the originally diagnosed fault data and the downgrade action-related data will disappear after the reset, resulting in inconsistent states of the faulty vehicle before and after the reset.

[0044] Based on this, an embodiment of the present invention provides a vehicle control method, which is applied to a controller. As an improvement on the existing controller, the controller can be considered as an electronic control unit (Electronic Control Unit, ECU). For example, it can be used as a vehicle control unit (VCU) or a domain controller for electric vehicles. As the central control unit of a new energy vehicle, the VCU is the core of the entire control system and can be responsible for managing and coordinating various functions of the vehicle. According to the driver's intention, the vehicle's operating status and the vehicle's control strategy, after calculation and analysis, it issues corresponding control commands to each component to achieve high-performance and safe driving of the electric vehicle. The domain controller can be designed for specific functional areas (such as power, body, infotainment, etc.), can process data from various sensors, and implement corresponding control through actuators. According to the classification of automobile functions, the domain controller can include a power domain controller, a chassis domain controller, a cockpit domain controller, an automatic driving domain controller, etc. The controller provided by the present invention is not specifically limited. A state detection module and underlying software are deployed in the controller, wherein the state detection module is a software module in the controller. The vehicle control method provided by the present invention is described in detail below. Figure 1 FIG. 1 is a flow chart showing a first embodiment of a vehicle control method of the present invention, wherein the method is executed by a controller, specifically, the controller is a VCU as an example. Figure 1 As shown, the method comprises the following steps:

[0045] Step 110: Generate a status identifier after performing the reset operation.

[0046] The state identifier is used to represent the state of the target data of the vehicle before the reset. The target data is stored in a preset area. The data in the preset area will not be cleared during the reset operation.

[0047] The controller provided in the embodiment of the present invention can be used to implement a series of functions such as analysis, processing, and transmission of vehicle data. The underlying software is provided in the electronic control unit, which can enable the hardware functions of the electronic control unit to be implemented. The state detection module is a software module of the controller application layer that can be used for vehicle fault diagnosis. It can continuously detect the operating status of the vehicle during the operation of the vehicle, determine whether the vehicle has a fault, and perform fault processing (for example, downgrade processing) according to the vehicle fault situation. Fault processing is usually a measure taken by the system when the automatic driving system fails, the performance degrades, or encounters a complex scenario that exceeds its processing capacity. Different fault handling methods can be used according to different situations, for example, downgrading from a fully automatic driving mode to an assisted driving mode, or from an assisted driving mode to a manual driving mode. The underlying software and the application layer can be associated through the middle layer, and data transmission between the underlying software and the application layer can be achieved through a specific data association mechanism.

[0048] The status detection module transmits the detected status detection data to the underlying software and stores it in the preset area of ​​the underlying software. The preset area is a specific address segment. The data stored in the preset area will not be affected by the reset operation and will not be cleared due to the reset operation. The reset operation has nothing to do with the data in the preset area. The target data is the last status detection data received by the controller before the reset operation.

[0049] The underlying software has an arbitration function. After the reset operation, the arbitration function is enabled to detect the state of the target data stored in the preset area, and then generate a corresponding state identifier. The state identifier is used to characterize the state of the vehicle's target data before the reset. The data state includes whether the data is complete. The state identifier can represent different data states, that is, different data states can be represented by different values. The state of the target data is continuously detected during the reset operation, and a unique state identifier is determined after the controller reset is completed.

[0050] Step 120: Determine whether to read target data based on the state identifier and the current software running cycle.

[0051] Whether the target data needs to be read is determined based on the value of the status identifier and the current operation cycle, and can be specifically read from the preset area of ​​the underlying software by the status detection module. Among them, determining the operation cycle may include determining whether it is in the first software operation cycle after reset. The target data includes fault-related data, including fault codes, fault downgrade requirements, fault judgment status, etc.

[0052] Step 130: If it is determined to read the target data, the vehicle is controlled according to the target data.

[0053] If it is determined that the target data is to be read, the state detection module reads the target data from the preset area, and controls the vehicle by reading the target data. The target data may store control instructions for the vehicle before the vehicle is reset. The control instructions are generated based on the vehicle state, such as vehicle fault handling instructions. If the target data is not read, the vehicle state can be detected normally based on the current situation, and then the fault control method for the vehicle can be determined based on the detection results.

[0054] The vehicle control method provided by the embodiment of the present invention is applied to a controller, and a state identifier is generated after a reset operation is performed, wherein the state identifier is used to characterize the state of the target data of the vehicle before the reset, the target data is stored in a preset area, and the reset operation is irrelevant to the data in the preset area; based on the state identifier and the current software operation cycle, it is determined whether to read the target data; if it is determined to read the target data, the vehicle is controlled according to the target data. This method can store the target data of the vehicle before the reset, and after the reset operation, it can determine whether to read the target data before the reset and then control the vehicle in combination with the state identifier and the current software operation cycle, thereby ensuring that the vehicle is in the same state before and after the reset operation, reducing vehicle safety risks, improving operating performance, and ensuring user experience.

[0055] In some embodiments, the vehicle control method further includes: detecting the state of the vehicle to obtain state detection data, and storing the state detection data in a preset area; if a reset operation is required, determining the target data before the reset from the state detection data.

[0056] The status detection module continuously detects the status of the vehicle and obtains status detection data, which includes fault-related data, including fault codes, fault downgrade requirements, fault judgment status, etc. The status detection data is sent to the underlying software and stored in the preset area. Since the status detection data changes in real time, when the controller needs to perform a reset operation, the underlying software determines the target data before the reset operation from the status detection data to ensure that the target data is the latest data before the reset operation is performed.

[0057] Based on the above-mentioned embodiments, this embodiment shows a second embodiment of the vehicle control method of the present invention. Figure 2 A flow chart showing a second embodiment of a vehicle control method of the present invention is shown, the method comprising the following steps:

[0058] Step 210: Generate a status flag after performing the reset operation.

[0059] Specifically, step 210 includes:

[0060] Step 211, after performing the reset operation, detect whether the target data is complete and obtain a detection result.

[0061] The underlying software of the controller has an arbitration function. After the controller is reset, the arbitration function is enabled to determine whether the target data stored in the preset area is damaged or valid. The integrity of the target data means that there is no data damage, loss, invalidity, etc.

[0062] Step 212: determine the value of the state identifier based on the detection result to generate a state identifier.

[0063] The state of the target data can be represented by different values, for example, when the detection result represents that the target data is complete, the state identifier = 1, and when the detection result represents that the target data is incomplete, the state identifier = 0. By detecting the target data, a corresponding state identifier is generated, and the state identifier can be sent to the state detection module.

[0064] Step 220: Determine whether to read the target data based on the state identifier and the current software running cycle.

[0065] Specifically, step 220 includes:

[0066] Step 221 : if the status flag indicates that the target data is complete and the current software running cycle is the first software running cycle after the reset operation, the target data is read from the preset area.

[0067] Different types of vehicles (such as passenger cars, commercial vehicles, electric vehicles, etc.) and different vehicle systems (such as engines, braking systems, electrical systems, etc.) may have different fault detection requirements. Therefore, the operating cycle of the software where the status detection module for these vehicles and systems is located will also be different. After the reset is completed, the status detection module restarts. After startup, a series of initialization operations are required, such as loading configurations, establishing connections, etc. The time of this stage is usually short, but it depends on the complexity of the software and the operating environment. When entering the detection state, the vehicle system is detected according to the set detection method and frequency. The time of this stage depends on the frequency of detection and the complexity of the vehicle system. Each operating cycle can be set to the same duration or different durations, which can be set according to actual conditions.

[0068] After obtaining the state identification, if the state identification indicates that the target data is complete, the state detection module detects the current software operation cycle. If the current operation cycle is the first operation cycle after the reset operation, the state detection module reads the target data from the preset area.

[0069] Step 222: If the status indicator indicates that the target data is incomplete or the current software operation cycle is not the first software operation cycle after the reset operation, it is determined that there is no need to read the target data, and the current operation state of the vehicle is detected to control the vehicle.

[0070] If the state identifier indicates that the target data is complete, the current software operation cycle is detected. After detection, if the current software operation cycle is not the first operation cycle after the reset operation, since the state detection module is executed in cycles, it indicates that the state detection module has detected the vehicle state at that time in the first operation cycle after the reset is completed and may determine the vehicle control method (including fault handling method) according to the situation at that time. Therefore, there is no need to read the target data in the second operation cycle and subsequent operation cycles. The state detection module can detect the current operating state of the vehicle and determine the vehicle control method based on the detected current vehicle operation data. If it is detected that the current vehicle has a fault and needs to perform fault handling, the corresponding fault handling method can be determined according to the fault situation, so that the vehicle operates according to the fault handling method.

[0071] If the status mark indicates that the target data is incomplete, it means that the target data may be damaged to a certain extent during the reset process, and the target data cannot be read and the corresponding operation cannot be performed. Therefore, when the received status mark indicates that the target data is incomplete, there is no need to read the target data. The status detection module can detect the current operating state of the vehicle and determine the vehicle control method based on the detected current vehicle operating data. If it is detected that the current vehicle has a fault and fault handling needs to be performed, the corresponding fault handling method can be determined according to the fault situation, so that the vehicle operates according to the fault handling method.

[0072] Step 230: If it is determined to read the target data, the vehicle is controlled according to the target data.

[0073] Specifically, step 230 includes:

[0074] Step 231 , analyzing the target data to determine whether the vehicle is in a fault state before the reset operation.

[0075] The target data includes the vehicle operating status before the reset operation, and may contain data related to fault detection and degradation processing. By reading the data, it is determined whether the vehicle is in a fault state before the reset operation is performed.

[0076] Step 232: If the vehicle is in a fault state before the reset operation, determine the fault handling method of the vehicle before the reset operation from the target data.

[0077] Step 233, controlling the vehicle based on the fault handling method.

[0078] If a vehicle fault is detected before the reset operation and the fault handling is performed, the fault data and fault handling data will be recorded in the target data, and the fault handling method includes the fault data and fault handling data. Usually, the downgrade process is completed within one operation cycle. When the vehicle is in a fault state before the reset operation is performed, it indicates that the vehicle fault has been detected before the reset and the fault handling has been performed, and the vehicle is in a fault state. In order to keep the vehicle in the corresponding fault handling state in the first software operation cycle after the reset, it should be consistent with the state before the reset. The vehicle is controlled to execute the fault handling method by reading the fault data and fault handling data.

[0079] If it is found through reading the target data that the vehicle is not in a fault state before performing the reset operation, no fault processing is required, and the state detection module in the controller can operate normally to detect the current state of the vehicle.

[0080] The fault state of the vehicle may include various types of faults, such as high-voltage faults, power-related faults, gear faults, etc. Different faults have corresponding fault handling methods. For example, when a high-voltage fault occurs, the fault handling method includes cutting off the high-voltage power to prevent the fault from expanding; when a power-related fault occurs, the fault handling method includes limiting the power output of the vehicle, activating the backup power system, etc.

[0081] In the vehicle control method provided by the embodiment of the present invention, the vehicle state can be detected to obtain state detection data, and a state identifier is generated after the reset operation. If the state identifier indicates that the target data is complete and is in the first software operation cycle, the target data is read, and it is determined whether the vehicle is in a fault state before the reset operation is performed based on the target data. If it is detected that the vehicle is in a fault state before the reset, the vehicle is controlled to execute the fault handling method in the target data. If the state identifier indicates that the target data is complete or the current software operation cycle is not the first software operation cycle after the reset operation, the current operating state of the vehicle is detected. Through this method, the vehicle that performs fault handling can continue to maintain the fault handling state after the reset, and the fault data will not be lost due to the reset operation. For the user, the situation that the vehicle state changes due to the reset will not be perceived, thereby improving the user experience.

[0082] In some embodiments, Figure 3 As shown, the above method also includes the following steps:

[0083] Step 310: Obtain a preset processing time corresponding to the fault handling method.

[0084] It takes some time to read the fault handling method and complete the execution. After reading the target data, a certain delay time can be processed. The delay time will be set according to the actual situation to ensure that it can be executed for different degradation actions or different fault states. The delay time is the preset processing time. Different fault handling methods can set corresponding preset processing times. After determining the fault handling method, the corresponding preset processing time is obtained. For example, if the complete process of executing a certain fault handling method requires 500ms, then the corresponding preset processing time is 500ms.

[0085] Step 320, detecting whether the process of controlling the vehicle by the fault handling method is completed within a preset processing time.

[0086] After the fault handling method is obtained, the fault handling method can be executed on the vehicle to detect whether the process of controlling the vehicle is completed within a preset processing time.

[0087] Step 330, if completed, then detect the current running state of the vehicle to control the vehicle.

[0088] The current running state is used to control the vehicle. If the vehicle is controlled according to the fault handling method within the preset processing time, the state detection module can restore the normal detection state to detect the current running state of the vehicle.

[0089] The method of this embodiment provides a certain delay time for vehicle control by setting a preset processing time corresponding to the fault handling method, thereby ensuring that the vehicle fault handling is completed within the preset processing time.

[0090] As an example, Figure 4 The flowchart of the vehicle control method provided by the present invention is shown in the figure. The execution subject is a controller. After the reset operation, a status identifier is generated. When the status identifier = 1, it means that the target data is complete, and then it is determined whether the current operation is the first operation cycle. When it is in the first operation cycle, the target data is read, and based on the result of reading the target data, it is determined whether the vehicle is in a fault state before the reset operation is performed. When it is not the first operation cycle, the current operation state of the vehicle is detected, and the vehicle is controlled according to the current operation state without reading the target data. When the status identifier is not equal to 1, the current operation state of the vehicle is detected, and the vehicle is controlled according to the current operation state without reading the target data.
