| Abstract: | According to the practical need of modifying a traditional car of Great Wall Motor into an EV andthe design requirements of vehicle control system, a vehicle control unit for the EV is designed. The method ofhardware circuit design, including power management, CAN communication, input signal processing and relay driving,is described in details. The design scheme based on dual MCU enhances the hardware fault diagnostic capacity ofvehicle control unit and its reliability. |
