A control method is applied to a hybrid power system including an engine and a motor. A motor stator of the motor is connected to a driving shaft of a motor vehicle by means of a transmission mechanism such that, when rotated, the driving shaft drives the motor stator to rotate; the motor is used to determine output torque according to the rotating speed of the motor and transmit same to the driving shaft; the rotating speed of the motor is equal to the difference between the rotating speed of the motor rotor and the rotating speed of the motor stator. The method includes, according to operating parameters of the hybrid power system and operating parameters of the motor vehicle, controlling a motor controller to provide a drive signal to the motor stator such that the operating parameters of the motor meet a first preset formula.

Control method and system for hybrid power system

A hybrid power system includes an engine and a motor. A motor stator of the motor is connected with a drive shaft of a motor vehicle through a transmission mechanism, so that the motor stator can also rotate relative to the chassis and other structures of the motor vehicle, thus, the hybrid power system composed of the engine and the motor can meet the application of various working conditions such as starting, idling, forwarding and reversing of the motor vehicle, and the number of parts of the hybrid system is greatly reduced, thereby simplifying the overall structure of the hybrid power system.
