7) feedback braking pattern
When trampling brake pedal, first clutch 510 and second clutch 520 are all in off-state.Feedback braking pattern comprises three kinds:
(1) brake power reaches 300 rotations of diff drive output shaft by the wheel of vehicle, then by one group in many groups odd number gear gear pair, pass to the first input shaft 210 successively, by the first transmission component, drive the first motor 610 generatings again, reclaim braking energy.
(2) brake power reaches 300 rotations of diff drive output shaft by the wheel of vehicle, then by one group in many groups even number gear gear pair, pass to the second input shaft 220 successively, by drive the second motor 620 generatings by the second transmission component, reclaim braking energy again.
(3) brake power reaches 300 rotations of diff drive output shaft by the wheel of vehicle, and then a part passes to the first input shaft 210 by one group in many groups odd number gear gear pair successively, then drives the first motor 610 generatings by the first transmission component; Another part passes to the second input shaft 220, the second input shafts 220 by one group in many groups even number gear gear pair successively and drives the second motor 620 generatings by the second transmission component.That is to say, braking energy drives the first motor 610 and the second motor 620 to generate electricity simultaneously, can reclaim more energy thus.
That is to say, under braking mode, hybrid power system 1 can, according to the degree of depth of the speed of a motor vehicle and brake pedal, be selected different gears and motor or drive the first motor 610 and the second motor 620 generatings simultaneously automatically.
8) pattern of reversing gear
While reversing gear, combustion engine 100 is not worked, and the first motor 610 can reverse.The power of the first motor 610 is passed to output shaft 300, thereby is realized the reversing of vehicle by first clutch 510, a gear driving gear 11, a gear driven gear 12 successively.
Wherein, the first speed of a motor vehicle predetermined value, the second speed of a motor vehicle predetermined value, the 3rd speed of a motor vehicle predetermined value, the first electric weight predetermined value, the second electric weight predetermined value and the first predetermined Das Gaspedal degree of depth can arrange according to the actual conditions of vehicle.
