  • Patent number: 11919399
    Abstract: 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.

  • Publication number: 20220176937
    Abstract: A control method for a hybrid power system. The method is applied to a hybrid power system composed of an engine (10) and a motor (20). A motor stator (21) of the motor (20) is connected to a driving shaft (40) of a motor vehicle by means of a transmission mechanism (32) such that, when rotated, the driving shaft (40) drives the motor stator (21) to rotate; the motor (20) is used to determine output torque according to the rotating speed of the motor and transmit same to the driving shaft (40); the rotating speed of the motor is equal to the difference between the rotating speed of the motor rotor (22) and the rotating speed of the motor stator (21).
