Working process and the principle of the present invention are as follows:
1. engine starting pattern
Operation conditions according to whole car, engine starting pattern is divided into static startup and driving to start. The common trait of these two kinds of Starting mode is: the first lock device 3 is separated with the 2nd lock device 13, super capacitor 15 discharges, a motor 12 works in a form of an electric motor, electric energy is converted into mechanical energy, power is delivered to engine 1 through front-seat sun gear 4, front-seat satellite gear 7, planet carrier 5, input shaft 2, and engine 1 starts. The difference of two kinds of subpatterns is: during static startup, No. two motors 8 do not work, and front-seat gear ring 6 rotating speed is zero, and rear seniority among brothers and sisters star-wheel 17, rear row's sun gear 16, rear ring gear 18 and No. two motors 8 dally, and power transmission line is as shown in Figure 2; When driving starts, the internal rotor 11 of No. two motors 8 works in a form of an electric motor, and electric energy is converted into mechanical energy, and front-seat gear ring 6 rotating speed is not zero, and power transmission line is as shown in Figure 3.
2. electric-only mode
Electric-only mode is mainly used in when super capacitor 15 state-of-charge (SOC) value is higher, and vehicle start, underload travel and reversing. Under this pattern, first lock device 3 engages, 2nd lock device 13 is separated, super capacitor 15 discharges, the internal rotor 11 of No. two motors 8 works in a form of an electric motor, and electric energy is converted into mechanical energy, power through after arrange sun gear 16, after rank star-wheel 17, front-seat satellite gear 7, front-seat gear ring 6, it is delivered to output gear 19, then exports whole car driving wheel to; Engine 1 and planet carrier 7 are fixed, and a motor 12 and front-seat sun gear 4 dally. During reversing, the internal rotor 11 of No. two motors 8 reverses work in a form of an electric motor, and other process is identical. Under this pattern, the required whole energy of vehicle movement is from super capacitor 15, and power transmission line is as shown in Figure 4.
3. engine drives separately pattern
Engine drives separately pattern to be mainly used in underload when middle load travels lower with super capacitor 15 state-of-charge (SOC) value and cruises, according to whole car operation conditions, engine drives separately pattern to be divided into power directly to transmit and shunts two kinds of subpatterns with power. When vehicle carries out middle load traveling, when whole car traveling demand power is in engine high-efficiency district, it is the direct transfer mode of power; Cruising when vehicle carries out underload, whole car travels the minimum power that power demand provides in efficient district lower than engine, and when super capacitor 15 state-of-charge (SOC) value is lower, is power shunt mode.
The common trait of these two kinds of subpatterns is: the first lock device 3 is separated, and engine 1 works, and power is passed to output gear 19 through input shaft 2, planet carrier 5, front-seat satellite gear 7, front-seat gear ring 6, then exports whole car driving wheel to; The required all power of vehicle movement all comes from engine 1; Rear seniority among brothers and sisters star-wheel 17, rear row's sun gear 16, rear ring gear 18 and No. two motors 8 dally. The difference of two kinds of subpatterns is: when power directly transmits, and the 2nd lock device 13 engages, and a motor 12 and front-seat sun gear 4 do not work, and the power that engine 1 exports is all for driving vehicle movement, and power transmission line is such as Fig. 5; When power is shunted, 2nd lock device 13 is separated, a motor 12 works with the form of generator, mechanical energy is converted into electric energy, the power that engine 1 is exported is a part of for driving vehicle movement, another part is stored in super capacitor 15 with the form of electric energy, and now vehicle is in electronic infinite variable speed state, and power transmission line is as shown in Figure 6.
4. combine driving pattern
Associating driving pattern is mainly used in high loading and travels and run at high speed most. When vehicle carries out high loading traveling, first lock device 3 is separated, 2nd lock device 13 engages, a motor 12 and front-seat sun gear 4 do not work, super capacitor 15 discharges, and the internal rotor 11 of No. two motors 8 works in a form of an electric motor, and electric energy is converted into mechanical energy, jointly driving vehicle with engine 1, power transmission line is as shown in Figure 7. When vehicle is run at high speed most, first lock device 3 is separated with the 2nd lock device 13, super capacitor 15 discharges, the outer rotor 10 of a motor 12, No. two motors 8 works all in a form of an electric motor, electric energy is converted into mechanical energy, jointly driving vehicle with engine 1, power transmission line is such as Fig. 8, and now a motor 12 reverses.
5. braking mode
When super capacitor 15 state-of-charge (SOC) value is lower and the speed of a motor vehicle higher than certain value time, vehicle can carry out regenerative braking, first lock device 3 is separated with the 2nd lock device 13, a motor 12 dallies, No. two motors 8 work with the form of generator, and damping force is provided, vehicle energy is converted into electric energy and is stored in super capacitor 15, and power transmission line is as shown in Figure 9.
It is noted that when No. two motors 8 are not enough to provide required braking moment, vehicle will adopt the Associated brake pattern of regenerative braking, engine anti-dragged brake and friction braking acting in conjunction.
