The vehicle controller needs to have enough I/O interfaces to quickly and accurately collect various input information, and at least two A/D conversion channels are used to collect accelerator pedal signals and brake pedal signals. There should be multiple The switch input channel is used to collect the car gear signal, and it should have multiple power drive signal output channels for driving the vehicle relay.
The vehicle controller should have a variety of communication interfaces, the CAN communication interface is used to communicate with the motor controller, battery management system and vehicle information display system, the RS232 communication interface is used to communicate with the upper computer, and an RS-485/ 422 communication interface, which can be compatible with devices that do not support CAN communication, such as some models of car touch screens.
Under different road conditions, the car will encounter different shocks and vibrations. The vehicle controller should have good shock resistance to ensure the reliability and safety of the car.
