[0024] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0025] It should be noted that the terms "first," "second," etc. (if applicable) used in the specification of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application.

[0026] This application provides a vehicle control method; please refer to the embodiments provided. Figure 1 The diagram illustrates an implementation environment for the method provided in this embodiment. This implementation environment may include a terminal 11 and a vehicle 12, with the terminal 11 and vehicle 12 establishing a communication connection via a wired or wireless network.

[0027] The terminal 11 is located on the vehicle 12. The terminal 11 can obtain the operating status information of the vehicle 12, and then the terminal 11 can control the vehicle 12 according to the operating status information, so that the vehicle 12 remains unchanged in the operating state corresponding to the operating status information. Optionally, the terminal 11 may be a vehicle controller capable of executing the vehicle control method provided in the embodiments of this application.

[0028] In one possible implementation, the environment further includes a server 13, which communicates with both the vehicle 12 and the terminal 11 via a wired or wireless network. Optionally, the terminal 11 can send the acquired operating status information of the vehicle 12 to the server 13. Based on the operating status information, the server 13 obtains control commands for the vehicle 12's operating status and sends these commands to the terminal 11, enabling the terminal 11 to control the vehicle 12's operating status according to the commands. In this embodiment, the server 13 can be a single vehicle server, a server cluster consisting of multiple vehicle servers, or a cloud computing service center.

[0029] See Figure 2 , Figure 2 This application provides a flowchart of a vehicle control method, which can be applied to... Figure 1 The implementation environment shown is, for example, by Figure 1 The terminal 11 shown executes this method. For example... Figure 2 As shown, the method includes, but is not limited to, the following steps 201 and 202.

[0030] Step 201: Obtain vehicle operating status information. The operating status information is information indicating the vehicle's operating status during the inspection process. The operating status information includes at least one of the following: inspection mode information, battery status information, gear information, hood status information, power mode information, and engine status information.

[0031] In this embodiment, if the vehicle needs to undergo a testing process, the vehicle must be in the operating state required by the testing process. Therefore, the vehicle's operating status information can be obtained through the controllers of various vehicle components. This application does not limit the content of the operating status information, as long as it indicates the vehicle's operating status during the testing process. For example, the operating status information includes at least one of the following: testing mode information, battery status information, gear position information, hood status information, power mode information, and engine status information.

[0032] The detection mode information describes the current detection mode of the vehicle, such as engine detection, light detection, brake detection, airbag detection, and carbon canister detection; the battery status information describes the working status of the vehicle battery, including but not limited to battery charge, charging status, battery life, and battery status; the gear information describes the current gear of the vehicle, such as drive, reverse, neutral, and park; the hood status information describes the open or closed state of the vehicle's hood; the power mode information describes the current power distribution mode of the vehicle, such as Electric Vehicle (EV) mode and Hybrid Electric Vehicle (HEV) mode, where EV mode corresponds to the pure electric mode in this application embodiment, and HEV mode corresponds to the hybrid electric mode in this application embodiment; and the engine status information describes the working status of the vehicle's engine, including but not limited to engine speed, combustion efficiency, engine start-up, shutdown, and fault codes.

[0033] Optionally, this application embodiment uses the vehicle's HCU (Hybrid Control Unit) controlling the vehicle based on its operating status information as an example to illustrate the implementation method of the vehicle's HCU acquiring operating status information. The vehicle's HCU can acquire the vehicle's operating status information through the vehicle's sensors and / or controllers. The HCU manages the vehicle's powertrain, performing operations such as torque distribution between the generator and motor, switching on and off high-voltage circuits, and starting or stopping the engine based on the driver's driving intentions, the vehicle's driving status, and the operating status of each component.

[0034] Taking battery status information as an example, the vehicle's BMS (Battery Management System) collects parameters such as battery voltage, current, temperature, and SOC (State of Charge). The BMS collects, processes, and stores battery status information in real time during battery pack operation and exchanges information with external devices such as the HCU (Hardware Unit) to control the battery's state. The BMS and HCU can transmit information via the CAN (Controller Area Network) bus.

[0035] For example, see Figure 3The diagram illustrates the information transmission process. This embodiment uses a hybrid vehicle as an example. The BMS sends battery status information, power battery fault information, and high-voltage power-on / off status information to the HCU; the EMS (Engine Management System) sends engine status information, engine fault information, and fuel level information to the HCU, and the HCU sends engine start / stop signals to the EMS; the TCU (Transmission Control Unit) sends vehicle gear information and transmission fault information to the HCU; the MCU (Motor Control Unit) sends motor fault information to the HCU; the IHU (Instrument Head Unit) sends vehicle power mode information and hood status information to the HCU; the vehicle's on-board diagnostic tool sends its fault information to the HCU, and the HCU can send the vehicle's detection mode information to the on-board diagnostic tool.

[0036] Step 202: Control the vehicle according to the operating status information so that the vehicle remains in the operating status corresponding to the operating status information.

[0037] In this embodiment, the vehicle operating status information obtained in step 201 indicates the vehicle's current operating status. Based on this information, the vehicle can be controlled to maintain its current operating status, preventing damage to the inspection personnel and the vehicle due to sudden changes in operating status during vehicle inspection. Furthermore, the vehicle's current motion status can be used to determine whether the vehicle meets inspection or maintenance conditions. This embodiment does not limit the inspection and maintenance conditions; they can differ depending on the specific inspection and maintenance situation. For example, if the vehicle's instrument panel is being inspected, the inspection conditions include powering on the vehicle to facilitate the display of instrument information.

[0038] In one possible implementation, when the vehicle's operating status information includes detection mode information, and the detection mode information indicates that the vehicle is to perform a carbon canister test, the vehicle's gear is kept in the parking position, and the vehicle's engine is kept running. Since the carbon canister test scenario requires the vehicle to be in the parking position and the engine to be running, keeping the vehicle in the parking position and the engine running ensures the normal operation of the carbon canister test and prevents test failure due to gear changes or engine shutdown.

[0039] Carbon canister inspection is used to check for malfunctions or failures in the carbon canister to determine if replacement or repair is necessary. The carbon canister's function is to adsorb and store gasoline volatiles to reduce environmental pollution and fuel waste. If the carbon canister fails, it can lead to fuel volatile leakage, affecting vehicle performance and fuel consumption, while also increasing environmental pollution. Therefore, regular carbon canister inspection is an important measure to maintain vehicle performance and safety.

[0040] Optionally, see Figure 4 The flowchart shown illustrates the carbon canister detection process, which includes, but is not limited to, the following steps: the vehicle's BMS performs a power-on operation based on the power-on signal sent by the HCU; the vehicle is placed in park to keep it stationary for easier detection; and the vehicle's engine management system performs an engine start operation based on the start signal sent by the vehicle controller. The carbon canister detection checks whether the carbon canister can effectively absorb gasoline volatiles to prevent air pollution during vehicle operation; therefore, the carbon canister detection must be performed with the engine running. The on-board diagnostic tool is connected to the OBD (On-Board Diagnostics) diagnostic port.

[0041] For example, OBD can monitor the engine management system and other functional modules of the vehicle in real time during vehicle operation. If any abnormalities are detected, it determines the specific fault based on a specific algorithm and stores it in the vehicle's memory as DTCs (Diagnostic Trouble Codes). This memory can be OBD-specific or borrowed from the memory of other modules such as the vehicle controller. Users can use an on-board diagnostic tool to read the fault codes, thus quickly locating the fault. The on-board diagnostic tool is a portable intelligent vehicle fault self-diagnostic instrument used to detect and analyze vehicle faults. It connects to the vehicle's OBD interface, reads faults present in the vehicle, and displays the fault information on its own screen, helping users identify the location and cause of the fault.

[0042] When the on-board diagnostic tool is connected to the vehicle's OBD interface, the vehicle's IHU (In-Hand Unit) selects the carbon canister detection mode. This embodiment does not limit the method of selecting carbon canister detection; it could be that the IHU receives a touch signal corresponding to carbon canister detection, or it could be that the IHU receives a voice signal corresponding to carbon canister detection, etc. When the IHU selects carbon canister detection mode, the vehicle's overall controller performs vehicle control according to the detection mode to maintain the vehicle's operating state. Specifically, the vehicle controller sends a signal to the vehicle's transmission control unit to prohibit gear shifting, ensuring the vehicle remains in parking gear and preventing vehicle movement due to gear changes. The vehicle controller also sends a signal to the vehicle's battery management system to prohibit power-off, preventing the engine from stopping due to power loss, thus ensuring the carbon canister detection process is uninterrupted.

[0043] If the carbon canister test is complete, the on-board diagnostic tool will notify the user of "carbon canister test complete" via display or voice announcement. A "Exit offline testing mode?" window will also appear on the on-board diagnostic tool's display. If a "Yes" touch signal is received, the offline testing is complete, and the connection between the on-board diagnostic tool and the OBD interface can be disconnected. Alternatively, if the on-board diagnostic tool receives a "No" touch signal, the user can continue to select other testing modes to check whether other vehicle functions meet the offline requirements.

[0044] Optionally, during the carbon canister detection process, the vehicle controller determines whether the vehicle meets the carbon canister detection conditions based on whether the vehicle's control module sends a fault signal. This allows the controller to execute the corresponding operation for carbon canister detection failure if the conditions are not met. For example, upon receiving a fault signal from the control module, the controller keeps the vehicle's engine stationary and powers off the vehicle. The control module includes at least one of the following: Battery Management System (BMS), Motor Control Unit (MCU), Engine Management System (EMS), and Transmission Control Unit (TCU).

[0045] For example, fault signals sent by the control modules include, but are not limited to: fault signals sent by the battery management system, fault signals sent by the engine management system, fault signals sent by the transmission control unit, and fault signals sent by the motor control unit. If the vehicle's overall controller receives any of the above fault signals, it indicates that at least one control module is faulty or the program sending the fault signal from the control module is faulty. If the control module is faulty, the detection operation should be stopped immediately to facilitate troubleshooting of the control module. If the program sending the fault signal from the control module is faulty, the detection operation should be stopped immediately to facilitate troubleshooting and repair of the program sending the fault signal from the control module, so as to prevent the program from failing to send fault signals when the control module is faulty.

[0046] For example, when the vehicle controller receives a fault signal, it must immediately stop the detection to prevent damage to the user or the vehicle. In this embodiment, the vehicle controller sends an engine stop signal to the vehicle's engine management system to keep the engine stationary, and sends a power-off signal to the vehicle's battery management system to power off the entire vehicle, thereby preventing potential damage to the user or the vehicle from dangerous situations such as leakage. Optionally, the vehicle controller sends a carbon canister detection failure signal to the vehicle's instrument cluster controller. Based on the carbon canister detection failure signal, the instrument cluster controller prompts the user. This prompt can take the form of displaying the text "Carbon canister detection failure" on the instrument cluster controller's display screen; or broadcasting a voice prompt about the carbon canister detection failure through the vehicle's audio system; or flashing or maintaining a constant indicator light on the vehicle.

[0047] In one possible implementation, the operating status information includes battery status information, gear position information, hood status information, power mode information, and engine status information; controlling the vehicle based on the operating status information includes: when the operating status information does not meet the operating conditions, after the hood status information indicates that the vehicle's hood has changed from closed to open, controlling the vehicle's engine to remain stationary; the operating conditions include the battery status information indicating that the vehicle's battery has high voltage, the gear position information indicating that the vehicle's gear is in parking gear, the power mode information indicating that the vehicle is in hybrid mode, and the engine status information indicating that the vehicle's engine fuel level is greater than the starting threshold, and the voltage of the high voltage is greater than the voltage threshold.

[0048] For example, the embodiments of this application are divided into two cases based on operating conditions: Case 1, the operating status information does not meet the operating conditions; Case 2, the operating status information meets the operating conditions. Wherein, the operating status information meeting the operating conditions means that the vehicle can operate in the operating state corresponding to the operating status information, and the operating status information not meeting the operating conditions means that the vehicle cannot operate in the operating state corresponding to the operating status information. The embodiments of this application do not limit the operating conditions. For example, operating conditions may include battery status information indicating that the vehicle's battery has high voltage, gear information indicating that the vehicle is in parking gear, power mode information indicating that the vehicle is in hybrid mode, and engine status information indicating that the vehicle's engine fuel level is greater than the starting threshold, and the voltage of the high voltage is greater than the voltage threshold.

[0049] Scenario 1: The running status information does not meet the running conditions.

[0050] Optionally, the scenario provided in this application embodiment is a vehicle after-sales maintenance and repair scenario. In this scenario, the vehicle controller controls the vehicle according to the operating status information, including but not limited to the following steps: the vehicle's engine management system controls the vehicle's engine to start according to the engine start signal sent by the vehicle controller; upon receiving the hood opening signal sent by the instrument cluster controller, it determines that the vehicle's operating status information does not meet the operating conditions and controls the vehicle's engine to remain stationary.

[0051] See Figure 5 The flowchart for vehicle maintenance shown indicates that if the engine is not started or has started but stopped, the vehicle controller sends a signal to the vehicle's engine management system to prohibit engine starting. If the engine is not started, it means that the current maintenance process must be carried out with the engine stationary, so engine starting is prohibited to ensure the safety of maintenance personnel. If the engine has stopped, it means that the engine may have a fault, so restarting the engine is prohibited to ensure that the engine will not be damaged by starting after a fault.

[0052] Optionally, if the engine is running and the hood remains closed after the running time exceeds a reference time, a signal to prohibit engine starting is sent to the engine management system to change the engine from running to a stationary state, thereby saving the energy consumed by the engine. If the engine is running and the hood changes from closed to open and then back to closed, it indicates that the engine detection may have ended, and the engine is shut down to save the energy consumed by the engine.

[0053] Optionally, if the engine is running and the hood is open, the vehicle's operating status information is determined. If the operating status information includes at least one of the following: battery status information indicating the battery is not charged with high voltage, gear information indicating the gear is not in parking mode, power mode information indicating the vehicle is not in hybrid mode, and engine status information indicating the engine fuel level is less than or equal to the starting threshold, then the operating status information does not meet the operating conditions. Specifically, if the battery is not charged with high voltage, it may not provide enough energy to start the engine, leading to starting failure; if the gear information indicates the gear is not in parking mode, the engine operation may cause the vehicle to move, posing a hazard to maintenance personnel; if the vehicle is not in hybrid mode, it indicates the vehicle may be in pure electric mode, thus eliminating the need to start the engine; if the engine fuel level is less than or equal to the starting threshold, insufficient fuel may cause the engine to suddenly stop during operation, posing a threat to maintenance personnel.

[0054] Therefore, if the operating state does not meet the operating conditions, the vehicle controller sends an engine start prohibition signal to the engine management system. The engine management system maintains the engine in a stationary state or changes the engine from a running state to a stationary state based on the engine start prohibition signal.

[0055] In addition, the voltage of the high-voltage electricity must be greater than the voltage threshold, which is determined experimentally during the vehicle design and manufacturing process. If the voltage of the high-voltage electricity is less than or equal to the voltage threshold, it may result in insufficient energy to start the vehicle's engine; or, during vehicle operation, if the battery voltage drops below the voltage threshold, it may cause the vehicle to suddenly stall, thereby interrupting the vehicle's operation; or, it may cause other electrically driven functions other than the motor to fail; or, it may affect the vehicle's acceleration performance, making the vehicle accelerate weakly or slowly.

[0056] Scenario 2: The operating status information meets the operating conditions.

[0057] If the vehicle's engine is running before the hood is opened, then after the hood status information indicates that the hood has changed from closed to open, the vehicle's engine will remain running. If the vehicle's engine is stationary after the hood status information indicates that the hood has changed from closed to open, then the vehicle's engine will remain stationary.

[0058] For example, see Figure 5 The flowchart shown in the vehicle maintenance diagram indicates that if the vehicle's engine is running before the hood is opened, the engine is kept running after the hood status information indicates that the hood has changed from closed to open. This keeps the vehicle running in the current maintenance scenario, facilitating maintenance work and preventing the danger caused by a sudden engine shutdown.

[0059] Optionally, if the engine is stationary with the hood open, a signal to prevent engine start is sent to the engine management system to avoid damage to maintenance personnel or the vehicle due to sudden engine start.

[0060] In one possible implementation, the operating status information includes battery status information, hood status information, and power mode information; controlling the vehicle based on the operating status information includes: when the power mode information indicates that the vehicle is in pure electric mode, after the hood status information indicates that the hood of the vehicle has changed from closed to open, if the battery status information indicates that the vehicle's battery has high voltage, controlling the vehicle's engine to remain stationary.

[0061] For example, in pure electric mode, the hood is already open before the vehicle's power battery is charged with high voltage. After the vehicle is charged with high voltage, it directly enters hybrid mode due to the low state of charge (SOC) of the power battery, at which point the engine is not allowed to start. Pure electric mode uses the electric motor to drive the vehicle; therefore, in pure electric mode, the engine may not be the focus of maintenance, and the engine remains stationary. Entering hybrid mode could cause the engine to start suddenly, potentially damaging maintenance personnel or the vehicle. Therefore, in this situation, the vehicle controller sends a signal to the vehicle's engine management system to prevent engine start, keeping the engine stationary.

[0062] In one possible implementation, the operating status information includes battery status information, hood status information, power mode information, and engine status information; controlling the vehicle based on the operating status information includes: when the power mode information indicates that the vehicle is in hybrid mode, the hood status information indicates that the hood has changed from closed to open, and the engine status information indicates that the engine is running, if the engine status information indicates that the engine has changed from running to stationary, controlling the engine to remain stationary.

[0063] For example, in hybrid mode, with the hood open and the engine running, if a malfunction causes the engine to stop, restarting the engine is not permitted even after the malfunction disappears. This means that when the vehicle is in hybrid mode, with the hood open and the engine running, if the engine suddenly stops, the system will control the engine to remain stationary. This control strategy is to avoid potential risks and ensure the safe and stable operation of the vehicle. After the malfunction disappears, maintenance work must be stopped, and potentially faulty modules must be checked and tested. Once the malfunction is confirmed to be resolved, the aforementioned vehicle maintenance work can be resumed.

[0064] In summary, the method provided in this application controls the vehicle based on its operating status information, so that the vehicle remains in the operating state corresponding to the operating status information. This avoids detection failures caused by changes in the vehicle's operating status during vehicle inspection or maintenance, improves the success rate of inspection, and avoids harm to the vehicle and personnel.

[0065] See Figure 6 This application provides a vehicle control device, which includes:

[0066] The acquisition module 601 is used to acquire the vehicle's operating status information.

The operating status information includes at least one of the following: inspection mode information, battery status information, gear information, hood status information, power mode information, and engine status information.

[0067] The control module 602 is used to control the vehicle according to the operating status information so that the vehicle remains unchanged in the operating state corresponding to the operating status information.

[0068] In one possible implementation, the operating status information includes detection mode information; the control module 602 is used to control the vehicle to remain in park and keep the vehicle's engine running when the detection mode information indicates that the vehicle is performing a carbon canister test.

[0069] In one possible implementation, the control module 602 is further configured to, upon receiving a fault signal sent by the control module, keep the vehicle's engine stationary and power off the vehicle. The control module includes at least one of a battery management system (BMS), a motor control unit (MCU), an engine management system (EMS), and a transmission control unit (TCU).

[0070] In one possible implementation, the operating status information includes battery status information, gear position information, hood status information, power mode information, and engine status information; the control module 602 is used to control the vehicle's engine to remain stationary after the hood status information indicates that the vehicle's hood has changed from closed to open, when the operating status information does not meet the operating conditions. The operating conditions include the battery status information indicating that the vehicle's battery has high voltage, the gear position information indicating that the vehicle's gear is in parking gear, the power mode information indicating that the vehicle is in hybrid mode, and the engine status information indicating that the vehicle's engine oil level is greater than the starting threshold, and the voltage of the high voltage is greater than the voltage threshold.

[0071] In one possible implementation, the control module 602 is further configured to, when the operating status information meets the operating conditions, if the vehicle's engine is in an operating state before the vehicle's hood is opened, then after the hood status information indicates that the vehicle's hood has changed from closed to open, control the vehicle's engine to remain in an operating state; if the vehicle's engine is in a stationary state after the hood status information indicates that the vehicle's hood has changed from closed to open, control the vehicle's engine to remain in a stationary state.

[0072] In one possible implementation, the operating status information includes battery status information, hood status information, and power mode information. The control module 602 is used to control the vehicle's engine to remain stationary if the battery status information indicates that the vehicle's battery is at high voltage after the hood status information indicates that the hood has changed from closed to open, when the power mode information indicates that the vehicle is in pure electric mode.

[0073] In one possible implementation, the operating status information includes battery status information, hood status information, power mode information, and engine status information; the control module 602 is used to control the vehicle's engine to remain stationary if the engine status information indicates that the vehicle is in hybrid mode, the hood status information indicates that the vehicle's hood has changed from closed to open, and the engine status information indicates that the vehicle's engine is in operation.
