The automatic transmission 3 of the embodiment of the present invention is provided with 6 gears, and wherein 1～5 grade is forward gear, and R shelves are reverse gear, and the 5th grade is top gear.
Dynamical system of the present invention mainly comprises following several mode of operation:
1, idling warming-up/idle stop mode of operation. Before the cold machine band of engine 1 carries and uses and move, because the water temperature of engine 1 is lower, ternary catalyzing unit not yet reaches normal working temperature, machine oil also not to lubricated in cylinder, system should enter idling warming-up pattern in advance, and rear engine 1 restarts and prepares fast for it; System control is started push button signalling etc. according to battery SOC, gear position operation bar position switch signal, brake pedal switching signal, engine 1, the idling of can stopping warming-up and idling warming-up under pure electronic mode of operation.
Parking idling warming-up. Now vehicle is in dead ship condition, and second clutch 35 separates (between driven gear 33 and output shaft 34, separating), automatic transmission 3 automatic hangings and enters the 5th grade, first clutch 2 and engage; Motor 9 starts and turns round, and its outputting power passes to engine 1 through travelling gear 8, transition gear 7, driving gear 32, power shaft 31, the first clutch 2 of the 5th grade; After engine 1 starting, first clutch 2 separates, and engine 1 keeps idle running, and system enters idling warming-up pattern; In the time that the water temperature of engine 1 reaches preset value, system switches to idle stop pattern, and engine 1 shuts down.
And under pure electronic mode of operation idling warming-up and following engine working mode principle basic identical, different: after engine 1 starting, first clutch 2 separates, and engine 1 keeps idle running, and system enters idling warming-up pattern under pure electronic mode of operation.
2, stopping for charging mode of operation. Now vehicle is in dead ship condition, and the electric weight of electrokinetic cell 11 is lower than setting value, and system pilots engine 1 by parking idling warming-up mode of operation; After starting, engine 1 is operated in minimum stable and above rotating speed, and first clutch 2 maintains joint, and motor 9 quits work; The power of engine 1 passes to motor 9 through first clutch 2, power shaft 31, driving gear 32, transition gear 7, the travelling gear 8 of the 5th grade and makes its rotation generating, for electrokinetic cell 11 charges.
3, pure electronic mode of operation. When the electric weight of electrokinetic cell 11 is during in normal range (NR), vehicle is with electric-only mode work; Now engine 1 stops standby, and first clutch 2 separates, second clutch 35 engages, automatic transmission 3 automatic hangings enter neutral gear; Electrokinetic cell 11 via controllers 10 are given motor 9 transmission of electric energy, the outputting power of motor 9 is delivered to wheel 6 through travelling gear 8, transition gear 7, driving gear 32, second clutch 35, output shaft 34, main reducing gear 4 and the differential mechanism 5 of the 5th grade, drives Vehicle Driving Cycle.
Note: pure electronic and following mode of operation, second clutch 35 is all located engagement state (engaging between driven gear 33 and output shaft 34), no longer repeats.
4, engine working mode. Under electric-only mode, along with the lifting of the speed of a motor vehicle, when vehicle power demand is positioned at the fuel efficient district of engine 1 or electrokinetic cell dump energy when lower, automatic transmission 3 enters corresponding gear according to the speed of a motor vehicle, accelerator pedal aperture automatic hanging, first clutch 2 engages gradually, motor 9, in continuing to drive vehicle speed-raising, distributes certain power to pass to engine 1 through travelling gear 8, transition gear 7, the driving gear 32 of the 5th grade, corresponding shifting gear, power shaft 31, first clutch 2; Engine 1 starts, system switches to engine working mode, the outputting power of engine 1 passes to wheel 6 through first clutch 2, power shaft 31, corresponding shifting gear, output shaft 34, main reducing gear 4, differential mechanism 5 and drives Vehicle Driving Cycle, and now motor 9 quits work and proceeds to servo-actuated state; If the dump energy of electrokinetic cell 11 is lower, the power of engine 1 is except driving vehicle, also a part of output excess power is passed to motor 9 through driving gear 32, transition gear 7, travelling gear 8, motor 9 is worked in the mode of generator, and charges for electrokinetic cell 11.
5, combination drive mode of operation. System held is at engine working mode, when vehicle power demand exceedes in the fuel efficient district of engine 1 in limited time, system is under engine working mode, motor 9 also participates in driving Vehicle Driving Cycle, be that engine 1 is coupled by driving gear 32 or output shaft 34 with the power of motor 9, and transmit and drive power to wheel 6 through output shaft 34, main reducing gear 4, differential mechanism 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 motor 9 by wheel 6, differential mechanism 5, main reducing gear 4, output shaft 34, corresponding shifting gear, driving gear 32, transition gear 7, travelling gear 8 and makes its rotation, motor 9 is converted to electric energy in generator mode by kinetic energy, charges to electrokinetic cell 11; The joint that first clutch 2 is controlled SOC according to the speed of a motor vehicle, brake pedal aperture, electrokinetic cell 11 in now system control with separate.
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 motor 9 reverse rotations and driven vehicle backings; In the time that SOC drops to setting value, pilot engine 1, system is pressed orthodox car mode by automatic transmission 3 reverse drive vehicle backings, and motor 9 is parallel in system, regulates engine 1 to work in low oil consumption district in generator mode, and charges to electrokinetic cell 11.
As mentioned above, just can well realize the present invention.
