The hardware circuit of the vehicle controller includes microcontrollers, switching value conditioning, analog conditioning, relay drive, high-speed CAN bus interface, power supply and other modules.
Microcontroller module The microcontroller module is the core of the vehicle controller. Considering the functions of the pure electric vehicle vehicle controller and the external environment in which it operates, the microcontroller module should have high-speed data processing performance and rich hardware interfaces. , low cost and high reliability.
Switching value conditioning module The switching value conditioning module is used for level shifting and shaping of switching input, one end of which is connected with a plurality of switching value sensors, and the other end is connected with a microcontroller.
Analog conditioning module The analog conditioning module is used to collect the analog signals of the accelerator pedal and the brake pedal and send them to the microcontroller.
