Abstract: Hybrid electric control system can reduce fuel consumption, reduce environmental pollution, and has good economy and power. By analyzing the functional requirements of the hybrid electric control system, the electric control system is designed from the single-chip selection of the electric control system, the design of the power supply circuit, the design of the input signal conditioning circuit and the design of the executive circuit. Develop a plan to test the functions of the hybrid electric control system, and carry out tests from two aspects of engine start control and regenerative braking control. It is concluded that the test parameters of the electric control system meet the design requirements, indicating that the hybrid electric control system can meet the requirements of the vehicle power demand.
