Note: pure electronic and following mode of operation, second clutch 35 is all located engagement state (driven gear 33 with output shaft 34 between engage), no longer repeats.
4, engine working mode.Under electric-only mode, lifting along with the speed of a motor vehicle, when vehicle power demand is positioned at the fuel efficient district of driving engine 1 or electrokinetic cell dump energy when lower, automatic transmission with hydraulic torque converter 3 enters corresponding gear according to the speed of a motor vehicle, acceleration pedal aperture automatic hanging, first clutch 2 engages gradually, electrical motor 9, when continuing to drive vehicle speed-raising, distributes certain power to pass to driving engine 1 through transmission gear 8, transition gear 7, the driving gear 32 of the 5th grade, corresponding shifting gear, input shaft 31, first clutch 2; Driving engine 1 starting, system switches to engine working mode, the outputting power of driving engine 1 passes to wheel 6 through first clutch 2, input shaft 31, corresponding shifting gear, output shaft 34, main reduction gear 4, diff 5 and drives Vehicle Driving Cycle, and now electrical motor 9 quits work and proceeds to servo-actuated state; If the dump energy of electrokinetic cell 11 is lower, the power of driving engine 1 is except driving vehicle, also a part of excess power of output is passed to electrical motor 9 through driving gear 32, transition gear 7, transmission gear 8, electrical motor 9 is worked in the mode of electrical generator, and is electrokinetic cell 11 chargings.
5, combination drive mode of operation.System held is at engine working mode, when surpassing in the fuel efficient district of driving engine 1, vehicle power demand prescribes a time limit, system is under engine working mode, electrical motor 9 also participates in driving Vehicle Driving Cycle, be that driving engine 1 is coupled by driving gear 32 or output shaft 34 with the power of electrical motor 9, and transmit and drive power to wheel 6 through output shaft 34, main reduction gear 4, diff 5; Now system switches to combination drive mode of operation by engine working mode.
6, slide/braking energy feedback pattern.When release the gas pedal or while stepping on brake pedal, system enters and slides/braking energy feedback pattern, vehicle energy passes to electrical motor 9 by wheel 6, diff 5, main reduction gear 4, output shaft 34, corresponding shifting gear, driving gear 32, transition gear 7, transmission gear 8 and makes its rotation, electrical motor 9 is converted to electric energy in electrical generator mode by kinetic energy, gives electrokinetic cell 11 chargings; Now system is controlled the joint of the SOC control first clutch 2 according to the speed of a motor vehicle, brake pedal aperture, electrokinetic cell 11 with separated.
7, reversing mode of operation.At electrokinetic cell SOC, during in range of normal value, system is with electric-only mode work, and controller 10 is controlled electrical motor 9 contrarotations and driven vehicle backings; When SOC drops to setting value, fire an engine 1, system is pressed orthodox car mode by automatic transmission with hydraulic torque converter 3 reverse drive vehicle backings, and electrical motor 9 is parallel in system, in electrical generator mode, regulates driving engine 1 to work in low oil consumption district, and gives electrokinetic cell 11 chargings.
As mentioned above, just can well realize the utility model.
