Abstract: Disclosed is a hybrid power transmission system including an engine, a power split device, a first electric machine, a second electric machine, a power controller, an energy storage module, and a wheel. The power split device is connected to the engine. The first electric machine is connected to the power split device. The second electric machine is connected to the power split device. The power controller is coupled to the first electric machine and the second electric machine. The energy storage module is coupled to the power controller. The wheel is connected to the second electric machine.

Abstract: An electric power split hybrid system comprises a case, a linkage unit, an electric power part, and a switching part. An engine, a generator, a motor, and a transmission mechanism are installed in the case. The generator is used to start the engine, and is capable of adjusting a torque of the engine and of generating electricity via driving of the engine. The transmission mechanism is used to link and move a wheel to rotate. The linkage unit is used to link and move the engine and the motor. The electric power part is used to store electrical energy generated by the generator and to supply electric power to the motor. The switching part is connected to the generator, the motor, and the electric power part. Electric power generated by the generator is switched by the switching part to supply to one of the motor and the electric power part.

Abstract: A hybrid vehicle having an engine, a starter, a motor/generator, a driving shaft, a compound planetary-gear device and a vehicle control device is disclosed. The vehicle control device is used for powering the hybrid vehicle by the motor/generator alone when a vehicle speed detected by a vehicle speed detection device is below a predetermined switching vehicle speed, and for starting the engine by the starter as well as turning off the motor/generator when the vehicle speed reached the predetermined switching vehicle speed, and for modulating an output driving torque by controlling a torque and a speed of the motor/generator.
