Abstract
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.
