Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of new energy vehicles, in particular to a vehicle power torque control method and device, an electronic device and a storage medium. BACKGROUND

[0002] With the popularity of intelligent and electrified new energy vehicles, the number of new energy vehicle controllers has increased dramatically. From the application point of view, new energy vehicle controllers are classified into power domain controllers, body domain controllers, cabin domain controllers, chassis domain controllers and intelligent driving controllers. The power domain controller includes but is not limited to the vehicle controller, the battery controller and the motor controller, the body domain controller includes but is not limited to the key controller, the window controller and the back door controller, the cabin domain controller includes but is not limited to the vehicle controller, the instrument controller, the HUD controller, the main driver monitoring controller and the screen rotation controller, etc., the chassis domain controller includes but is not limited to the body stability controller, the steering controller and the brake controller, etc., and the intelligent driving controller includes but is not limited to the lane departure controller, the adaptive cruise controller and the millimeter wave radar controller, etc. Among them, the power domain controller is mainly responsible for the driving function of the vehicle driving part. Due to the safety requirements of vehicle driving, very high requirements are put forward for the performance of the power domain controller. However, even the mainstream controller main chip will exist including but not limited to stack overflow, watchdog feeding timeout and other reasons to cause the controller to be in an abnormal state, at this time the controller must be restarted to quickly recover to the normal state. However, if the vehicle is driving, the power domain related controller restarts and restarts, the vehicle power drive will be abnormal, which will cause the vehicle power to be interrupted and bring great safety risks to the user.

[0003] For example, CN105700419B discloses a vehicle controller control method and device and a vehicle control method and system, wherein the vehicle controller control method includes: saving the driving parameters of the vehicle during driving; when the vehicle controller is initially running, determining whether the vehicle controller is normally powered on or has a fault and triggers the initialization after the controller reset according to the saved driving parameters; when it is determined that the vehicle controller triggers the controller reset due to a fault, the vehicle controller is switched to the running state before the reset occurs. This scheme solves the technical problem of ensuring the continuity of the controller running state after the restart by saving the driving parameters and reading the driving parameters after the vehicle controller restarts, but cannot solve the safety risk of the change of the driver's operation intention affecting the power torque control during the vehicle controller restart.

[0004] For another example, CN115214380A discloses a vehicle controller reset method, system and electric vehicle. The vehicle controller reset method includes the following steps: saving the driving parameters of the motor; according to the power-off instruction, the vehicle controller enters the sleep state; obtaining the driving parameters at a certain time before the power-off instruction and transmitting them to the motor; according to the restart instruction, the vehicle controller enters the reset state; obtaining the driving parameters at the same time, so that the motor maintains the driving parameters in the sleep state; according to the power-on instruction, the vehicle controller sends the driving parameters at the current time to the motor. When the vehicle controller goes through different stages such as sleep state, reset state and power-on state, the driving parameters of the motor change from the driving parameters at a certain time before the power-off instruction to the driving parameters at the current time. This scheme keeps the vehicle from shaking violently by using the driving parameters before restarting as the driving parameters during restarting, but still cannot solve the safety risk of power torque control caused by changes in driver's operation intention during restarting.

[0030] First of all, it needs to be pointed out that during the vehicle controller restart process, the following reasons cause power loss: first, due to the input and output drive failure of the vehicle controller and communication loss, the initial power controller is in an abnormal state or diagnoses power related faults, the vehicle power torque is limited or lost; second, during the vehicle controller restart process, the vehicle controller cannot collect the current power operation information, causing abnormal power torque control calculation, and the vehicle power torque is lost; third, during the vehicle controller restart process, the vehicle controller stops running, causing abnormal vehicle power torque control calculation, and the vehicle power torque is lost. And after the vehicle controller restarts, if the power torque control directly recovers to the state before the restart, unexpected acceleration and other safety problems will occur.

The vehicle controller 101 controls the battery controller 102 according to the battery main relay control, if the vehicle controller restarts, the battery controller 102 keeps working state according to the battery main relay control before the vehicle controller restarts.

[0032] The safety risk of the change of the driver's operation intention affecting the power torque control during the vehicle controller restart process cannot be solved.

[0033] To solve the above technical problems, the present application provides a vehicle power torque control method, device, electronic equipment and storage medium, and the implementation details of the technical solutions of the embodiments of the present application are described in detail.

[0034] Please refer to Figure 2 , Figure 2 The flowchart of the vehicle power torque control method according to an embodiment of the present application is shown. As Figure 2As shown, in an exemplary embodiment, the vehicle power torque control method comprises at least steps S210 to S230, which are described in detail as follows:

[0035] In step S210, current power operation information, key vehicle running parameters and working monitoring state of the vehicle controller are obtained.

[0036] In an embodiment of the present application, the current power operation information includes accelerator pedal electrical signal, brake pedal electrical signal, gear position and vehicle speed, and is obtained by driver operation intention and initial power controller. The driver operation intention includes driver throttle pedal operation information, brake pedal operation information and gear position operation information, and the throttle pedal operation information includes throttle pedal opening degree. The vehicle controller and the motor controller obtain the accelerator pedal 1 / 2 road electrical signal. The initial power controller is used to realize power torque control, and the initial power controller includes but is not limited to chassis controller and the like. The vehicle speed is transmitted to the vehicle controller and the motor controller by the controller area network (CAN) of the chassis controller.

[0037] In an embodiment of the present application, the key vehicle running parameters include but are not limited to vehicle running mode, power on / off state, key state, battery main electrical appliance closing state, battery working mode, motor working mode, vehicle driving mode, energy recovery level, cruise speed and chassis working state.

[0038] In an embodiment of the present application, before obtaining the working monitoring state of the vehicle controller, the working state of the vehicle controller is detected to obtain a first monitoring state. The working state detection includes but is not limited to hardware input / output detection, controller area network communication detection, controller power state detection, stack condition detection, task running time detection and watchdog monitoring detection, and the working monitoring state is determined to be abnormal or normal through the working state detection. The hardware input / output detection includes I / O drive detection, and the controller area network communication detection and the hardware input / output detection are controlled by the initial power controller. If at least one of the working state detection is abnormal, the working monitoring state is determined to be abnormal, and if all the working state detection is normal, the working monitoring state is determined to be normal.

[0039] In step S220, a restart monitoring state is obtained based on the working monitoring state, and the current power controller is determined according to the change of the restart monitoring state.

[0040] The current power controller includes the vehicle controller or the motor controller.

[0041] In an embodiment of the present application, the restart monitoring state is obtained based on the working monitoring state, including: if the first monitoring state is normal, determining the restart monitoring state as the working state of the vehicle controller being normal; if the first monitoring state is abnormal, determining the restart monitoring state as the vehicle controller being in the process of restarting; if the second monitoring state is restart completion, updating the restart monitoring state from the vehicle controller being in the process of restarting to the vehicle controller being in the process of restarting completion; and sending the restart monitoring state to the motor controller. The working monitoring state includes the first monitoring state and the second monitoring state, the first monitoring state is used to represent the working state of the vehicle controller before the restarting operation, and the second monitoring state is used to represent the completion state of the restarting operation of the vehicle controller.

[0042] In an embodiment of the present application, the restart flag is set to represent the restart monitoring state. For example, the vehicle controller being in the process of restarting is represented by the restart flag being 1, and the vehicle controller being in the process of restarting completion is represented by the restart flag being 0.

[0043] In an embodiment of the present application, the current power controller is determined according to the change of the restart monitoring state, including the vehicle controller or the motor controller, including: receiving the restart monitoring state; if the restart monitoring state is the vehicle controller being in the process of restarting, determining the motor controller as the current power controller; if the restart monitoring state is the vehicle controller being in the process of restarting completion, updating the current power controller from the motor controller to the vehicle controller; and if the restart monitoring state is the vehicle controller being in the working state, keeping the current power controller as the vehicle controller.

[0044] In an embodiment of the present application, after receiving the restart monitoring state, the vehicle power torque control method further includes: if the restart monitoring state is the vehicle controller being in the process of restarting, keeping the battery controller and the motor controller in the working state; and stopping the working state detection of the vehicle controller.

[0045] In an embodiment of the present application, during the restarting process of the vehicle controller, the communication information of the vehicle controller will be lost, resulting in the failure to receive the key parameters of the power torque control, such as the vehicle speed, the I / O drive being controlled to be pulled down, and the driver's throttle opening degree and brake pedal signal being collected being lost. Therefore, the power domain controllers such as the vehicle controller, the battery management controller and the motor controller need to be powered. Since the battery controller and the motor controller are awakened by the digital drive of the vehicle controller, after receiving the restart flag position 1 sent by the vehicle controller, the motor controller and the battery controller do not enter the sleep mode, but keep the working state, so as to avoid the power loss caused by the sleep of the battery controller or the motor controller. When the motor controller receives the restart flag position 1 of the vehicle controller, the current power operation information obtained is enabled, and the current power operation information is sent to the initial power controller through the motor controller as the current power controller and CAN communication.

[0046] In an embodiment of the present application, the stopping the working state detection of the vehicle controller comprises: setting the first controller area network communication to a preset default value; setting the second controller area network communication to current power operation information; stopping the hardware input and output detection of the vehicle controller; wherein the first controller area network communication is used for the controller area network communication detection between the initial power controller and the vehicle controller, the second controller area network communication is used for the power torque control of the initial power controller, and the initial power controller is used for being controlled by the current power controller to complete the power torque control.

[0047] In an embodiment of the present application, the initial power controller needs to stop the working state detection of the vehicle controller, that is, to shield the vehicle controller fault. The first controller area network communication is set to shield the CAN communication fault, which includes but is not limited to the cyclic redundancy check (CRC) fault, the counter COUNTER fault and the CAN loss fault, that is, the first controller area network communication is set to the preset default value, and the preset default value is used to stop the CAN communication fault detection signal. The second controller area network communication is sent to the initial power controller after the current power operation information is obtained through the motor controller. The I / O driving detection of the vehicle controller is stopped, that is, the I / O port information and the I / O driving are stopped for fault diagnosis, so as to avoid the power limitation or even the power loss after the diagnosis fault.

[0048] In an embodiment of the present application, if the first monitoring state is abnormal, the vehicle power torque control method further comprises: storing the vehicle running key parameters into a parameter temporary storage module; determining the restart monitoring state as the vehicle controller restart; and restarting the vehicle controller.

[0049] In an embodiment of the present application, the parameter temporary storage module includes but is not limited to an electrically erasable programmable read-only memory, that is, an E memory, so that after the vehicle controller is restarted, the control mode before the restart can be quickly recovered by reading the vehicle running key parameters in the E memory. The restart monitoring state is determined as the vehicle controller restart by setting the restart flag bit to 1.

[0050] In an embodiment of the present application, after the vehicle controller is restarted, the vehicle power torque control method further comprises: reading the vehicle running key parameters from the parameter temporary storage module and storing them into the vehicle controller; determining the second monitoring state as the restart completion; and detecting the working state of the vehicle controller through the initial power controller.

[0051] In an embodiment of the present application, the restart monitoring state is determined as the restart of the vehicle controller being completed by setting the restart flag to 0, and the restart flag is sent through CAN communication. The initial power controller resumes the CAN communication detection and I / O drive detection of the vehicle controller.

[0052] In an embodiment of the present application, the vehicle running key parameters are read by the parameter temporary storage module and stored in the vehicle controller, including: reading the vehicle running key parameters by the parameter temporary storage module; storing the vehicle driving key parameters in the vehicle torque control module; and storing the vehicle battery key parameters in the application management module; wherein the vehicle running key parameters include the vehicle driving key parameters and the vehicle battery key parameters, and the vehicle controller includes the application management module and the vehicle torque control module.

[0053] In an embodiment of the present application, after the restart of the vehicle controller is completed, the running key parameters are read out from the E-side memory. The vehicle battery key parameters include but are not limited to the vehicle running mode, the power-on / off state, the key state, the battery main electrical appliance closing state, the battery working mode and the motor working mode, so as to make the vehicle return to the high-voltage state; the vehicle driving key parameters include but are not limited to the vehicle driving mode, the energy recovery level, the cruise speed and the chassis working state, so as to make the vehicle in a drivable state. The application management module is used for managing the application layer high-voltage management logic, and the vehicle torque control module is used for managing the application layer vehicle torque control logic.

[0054] In an embodiment of the present application, if the motor controller receives the restart flag of the vehicle controller being 0, the current power torque control is exited by the motor controller, and the current power torque control is taken over by the vehicle controller after the current power operation information is acquired, so as to update the current power controller to the vehicle controller.

[0055] Step S230, performing power torque control on the vehicle according to the current power controller, the current power operation information and the vehicle running key parameters.

[0057] In an embodiment of the present application, when the power torque control is transitioned from being controlled by the vehicle controller to being controlled by the motor controller, the vehicle power torque needs to be filtered to maintain the driving comfort of the vehicle. When the power torque control is transitioned from being controlled by the motor controller to being controlled by the vehicle controller, the vehicle power torque needs to be filtered to maintain the driving comfort of the vehicle.

[0058] In one embodiment of the present application, if the current power controller is the vehicle controller, the motor torque request is obtained by the torque calculation module in the vehicle controller according to the current power operation information, and the motor demand torque in the motor torque request is sent to the motor through the motor controller to control the motor to perform the motor torque. If the current power controller is the motor controller, the motor demand torque is obtained by the torque calculation module in the motor controller according to the current power operation information, and is sent to the motor, and the motor performs the motor torque according to the motor demand torque. The vehicle power torque, i.e. the motor demand torque, is calculated by the torque calculation module according to the vehicle running key parameters and the current power operation information.

[0060] In the present application, the vehicle controller stores the vehicle running key parameters in the parameter temporary storage module during the restart process, and the motor controller takes over the power torque control, avoiding the situation that the vehicle loses power due to the restart of the vehicle controller, and avoiding the safety risk that the change of the driver's operation intention affects the power torque control; after the vehicle controller restarts, the vehicle running key parameters in the parameter temporary storage module are read and restored to the vehicle controller, and the vehicle controller takes over the power torque control again, the vehicle controller returns to the normal control state, and the driving safety is ensured. And the vehicle torque control is based on the current power operation information to control the power torque, that is, the power torque control is connected through the latest operation intention of the driver, and the safety problem in the power torque control connection is solved.
