The vehicle controller collects driving information such as accelerator pedal signal, brake pedal signal and gear switch signal, and simultaneously receives data from the motor controller and battery management system on the CAN bus, and analyzes the information in combination with the vehicle control strategy And judge, extract the driver’s driving intention and vehicle running status information, and finally send instructions through the CAN bus to control the work of each component controller to ensure the normal driving of the vehicle. The vehicle controller should have the following basic functions.
The function of vehicle driving control The driving motor of electric vehicles must output driving or braking torque according to the driver’s intention. When the driver depresses the accelerator pedal or the brake pedal, the drive motor should output a certain driving power or regenerative braking power. The larger the pedal opening, the larger the output power of the drive motor. Therefore, the vehicle controller should reasonably explain the driver’s operation; receive feedback information from each subsystem of the vehicle to provide decision-making feedback for the driver; send control commands to each subsystem of the vehicle to achieve normal driving of the vehicle.
