(4) journey pattern is increased
Combined by second clutch 5, driving engine 1 drives the first motor 2 to generate electricity, and an electric energy part delivers to the second motor 4 for driving, and a part is stored in battery.
(5) combination drive fast mode
First clutch 3, second clutch 5 and drg 9 are combined, driving engine 1 and motor 2 work simultaneously, to total output shaft 12 outputting power.
(6) combination drive low-speed mode
First clutch 3, second clutch 5 and the 3rd power-transfer clutch 10 are combined, driving engine 1 and motor 2 work simultaneously, to total output shaft 12 outputting power.
(7) braking potential take-back model
Combined by second clutch 5, when brake and descending, total output shaft 12 drives the second motor 4 to generate electricity, by power storage enter in battery.
Several mode of operation under control of the ecu above, and the control policy according to presetting automatically switches, and according to the running state of road conditions and vehicle, can automatically switch to optimum working mode, can reach best fuel-efficient object.
