Please in referring to Fig. 1 again in conjunction with Fig. 6, in the time need to being driven separately by main stator 11 and the integrated motor of main rotor 12, infinitely variable speed gearing in the present embodiment can switch to the independent drive pattern of motor as shown in Figure 6, now, electric machine controller is to main stator 11 and the integrated motor of main rotor 12 output electric energy and order about main rotor 12 by main stator 11 and rotate, and by main rotor 12, the outputting power of motor is all converted to mechanical energy and exports wheel to.For the independent drive pattern of motor, when load is during higher than the outputting power of motor or electrokinetic cell power shortage, can switch to engine and motor combination drive pattern as shown in Figure 3.
In addition, under the independent drive pattern of motor, composite rotors 13 also can be owing to producing idling loss with main rotor 12 electromagnetic coupled, therefore, preferably utilize clutch 30 to realize power shaft 23 and be in transmission connection with engine, can in the time that motor drives separately, engine and power shaft 23 be disconnected like this, to avoid engine to dally with the operation of motor;
In order to reduce as far as possible engine in the work of non-high efficiency point, preferably operational vehicle reverse gear and vehicle idling and braking under the independent drive pattern of motor.
In the time of operation reverse gear, only need the phase sequence of the three-phase output current that changes electric machine controller.
In the time of vehicle idling and braking, please in referring to Fig. 1 again in conjunction with Fig. 7, infinitely variable speed gearing in the present embodiment can switch to energy take-back model as shown in Figure 7, now, main stator 11 and main rotor 12 are as generator, and the mechanical energy in idling and when braking is converted to electrical energy transfer to electric machine controller, and by electric machine controller, electric energy is filled with to electrokinetic cell.
In addition, for fear of engine due to idling and braking and the loss causing that repeatedly starts and stop working, preferably utilize clutch 30 to realize power shaft 23 and be in transmission connection with engine, can reclaim while driving the starting state that engine and power shaft 23 is disconnected and kept engine at energy like this.
