Double clutch 11 works, and connect the second end 11b with third gear 12, and power transmission route is as shown in fig. 6, this mode
The power of lower motor 4 and engine 1 realizes overlapping at input shaft 3, then successively passes to third gear 12, the 6th gear
17, jackshaft 15, the 5th gear 16, first gear 19 and by differential mechanism 20 be transmitted to wheel end realize operation.
Electric-only mode C, engine 1 starting provide power, motor 4 start, first clutch 2, second clutch 8 with
Third clutch 9 works, and power transmission route is as shown in fig. 7, the power of motor 4 and engine 1 is in planet under this mode
It is coupled at row, and then passes to second gear 10, since second gear 10 is engaged with the 5th gear 16, so eventually by first
Gear 19, differential mechanism 20 are transmitted to wheel end and realize operation.
In addition mechanism also has the mode i.e. power dividing mode of an ECVT, and the specially starting of engine 1 provides dynamic
Power, motor 4 start, and first clutch 2 and third clutch 9 work, and power transmission route is as shown in figure 8, can from Fig. 8
To find out, the power transmission of motor 4 is to sun gear 5, and the power transmission of engine 1 is to planet carrier 6, in sun gear 5 and planet
Under the collective effect of frame 6, ring gear 7 is ultimately transferred to wheel end and realizes transport as export at transmitting power to second gear 10
The speed-change process of ring gear 7 may be implemented in row by the rotational speed regulation of motor 4 in such a mode, i.e., realization ECVT's is stepless
Speed change situation.
In addition the motor 4 in mixed dynamic Mode A, mixed dynamic Mode B, mixed dynamic model formula C, power dividing mode can be converted into hair
Motor form, when vehicle braking, generator generates braking moment, so that internal winding be made to generate induced current to vehicle
The battery of load charges, to carry out energy regenerating.
Demand according to the actual situation, mechanism can also be used internal combustion engine (i.e. engine 1) and directly drive mode, according to transmission ratio
Difference is also classified into three gears, specific as follows:
Internal combustion engine directly drives Mode A, and the starting of engine 1 provides power, and first clutch 2, double clutch 11 work, and makes the
One end 11a is combined with output shaft 14, and power transmission route is as shown in figure 9, the power of engine 1 passes through double clutch 11
First end 11a passes to output shaft 14 and successively passes on wheel end.
Internal combustion engine directly drives Mode B, and the starting of engine 1 provides power, and first clutch 2, double clutch 11 work, and makes the
Two end 11b are connect with third gear 12, and power transmission route is as shown in Figure 10, and the power of motivation 1 passes through double clutch 11
The second end 11b pass to third gear 12 and successively pass to wheel end on, so successively passing to third gear 12, the 6th tooth
Wheel 17, jackshaft 15, the 5th gear 16, first gear 19 are simultaneously transmitted to the realization operation of wheel end by differential mechanism 20.
Internal combustion engine directly drives mode C, and the starting of engine 1 provides power, first clutch 2, second clutch 8 and third clutch
Device 9 works, and power transmission route is as shown in figure 11, and second clutch 8 is connected and fixed ring gear 7 and the realization of sun gear 5, row
Star is arranged unitary rotation and is inputted by 6 power of planet carrier, then successively and then passes to second gear 10, due to second gear 10 and
5th gear 16 engagement, so being transmitted to wheel end eventually by first gear 19, differential mechanism 20 realizes operation.
For under internal combustion engine directly drive mode, using the starting source that generator 4 starts as engine 1, to 1 turn of engine
Fast normal rear generator 4 is closed.
It for switchover policy of the mechanism under different operational modes, is mainly controlled by several threshold values, different threshold values
Corresponding different operational mode, such as using will judge when motor 4 or engine 1, current SOC value of battery and different operation moulds
Required torque in the case of the power threshold relationship and present speed that are needed under formula and the pass of the torque threshold under different models
System.Different operational modes can all have the bound and efficiency of a power threshold (internal combustion engine is directly driven away outer) and torque threshold
Than tactful deterministic process is as follows:
The first step, the vehicle-mounted ECU of vehicle get current vehicle speed S1 and required torque value D1；
