Working process: when ignition lock 6 closes, hybrid vehicle enters mode of operation.When gear on-off is in neutral, driving engine 11 and motor 12 do not work, and all power-transfer clutchs are all in released state, all drgs are not braked.After gear on-off is put into gear, hybrid power control unit 7 is according to the signal of the sensors such as acceleration pedal, gear, braking, the speed of a motor vehicle, by analyzing, calculating the mode of operation determining each power-transfer clutch, drg, the pattern whether motor 12 and driving engine 11 work and work.The mode of operation of each power element, mode of operation and to switch be all automatically control, it also determines the mode of operation of hybrid vehicle.Meanwhile, the technical parameter such as rotor-position, motor temperature can also be fed back to hybrid power control unit 7 by motor 12, so that hybrid power control unit 7 can better be controlled by frequency converter 5 pairs of motors 12, and where necessary also can starting protection pattern.
1, when electrokinetic cell electric power storage is more sufficient
Ignition lock 6 closes, and hybrid power control unit 7, according to the rotating speed of the signal determination motor 12 of each sensor and rotation direction, is controlled frequency converter 5 according to preset program and controlled the work of motor 12 by frequency converter 5.Now, hang forward gear, motor 12 rotates forward, automobile advances traveling; Extension reverses gear, and motor 12 rotates backward, reversing automobile travels; Hang neutral, motor 12 does not rotate, automobile stagnation of movement.If now driving engine 11 does not work, the 3rd power-transfer clutch 13 is in engagement state, and first clutch 16, second clutch 15 are in released state, and the first drg 14 is not braked with second brake 21.
2, when electrokinetic cell electric power storage is not enough
Ignition lock 6 closes, when electrokinetic cell 2 drives automobile advance traveling to cause electric power storage not enough, hybrid power control unit 7 can control first clutch 16, second clutch 15, the 3rd power-transfer clutch 13 engage automatically, and motor 12 drives driving engine 11 to rotate, and operates with start the engine 11.Driving engine 11 drives the vehicle wheel rotation of automobile by simple planetary arrangement 20, main reduction gear 22, diff 23.Driving engine 11 drive automobile advance travel time, simple planetary arrangement 20 can form three advance gears, bottom gear, middle speed gear with directly keep off; During bottom gear, first clutch 16 engages, second clutch 15 is separated, and the first drg 14 is braked, second brake 21 is not braked; During middle speed gear, second clutch 15 engages, first clutch 16 is separated, and second brake 21 is braked, the first drg 14 is not braked; Directly during gear, first clutch 16 all engages with second clutch 15, and the first drg 14 is not braked with second brake 21; The mode of operation of the 3rd power-transfer clutch 13 depends on that whether driving engine 11 power is sufficient, when driving engine 11 power is sufficient, 3rd power-transfer clutch 13 is in engagement state, motor 12 transfers power generation mode to, driving engine 11 excess power is charged to electrokinetic cell 2, otherwise as driving engine 11 under power charges to give electrokinetic cell 2, then the 3rd power-transfer clutch 13 is in released state.When gear on-off extension reverses gear, hybrid power control unit 7 controls driving engine 11 by control unit of engine 9 and quits work, and motor 12 rotates backward, reversing automobile travels.Now, driving engine 11 does not work, and the 3rd power-transfer clutch 13 is in engagement state, and first clutch 16, second clutch 15 are in released state, and the first drg 14 is not braked with second brake 21.
The urgency of 3, advancing when travelling is slowed down, brake, exceed the speed limit operating mode
When the anxious deceleration of automobile advance traveling, braking or automobile speed exceed the maximum speed of setting, system operating mode transfers energy recuperation mode to automatically.Now, driving engine 11 does not work, and motor 12 transfers generator operation mode (now motor 12 is brushless, permanently excited direct current motor) to, and vehicle energy transfers electric energy to, charges to electrokinetic cell 2.There are two kinds of patterns: driving engine 11 is braking mode and general mode.When driving engine 11 is braking mode, first clutch 16, the 3rd power-transfer clutch 13, second clutch 15 are all in engagement state, and the first drg 14, second brake 21 are not braked, and except energy regenerating, the resistance of driving engine 11 also can be utilized to carry out regulation speed; During general mode, the 3rd power-transfer clutch 13 is in engagement state, and first clutch 16, second clutch 15 are in released state, and the first drg 14 is not braked with second brake 21.
4, when tune-up or debugging mode
When driving engine 11 needs maintenance or debugging, can operate driving engine Auxiliary control switch 8, when driving engine Auxiliary control switch 8 is in ignition location, control unit of engine 9 enters mode of operation, and the pertinent instruments such as multi-meter can be used to detect driving engine 11; When driving engine Auxiliary control switch 8 is in enable position, auxiliary starter 10 start the engine 11, after driving engine 11 successfully starts, driving engine Auxiliary control switch 8 should get back to ignition location, at this moment can overhaul driving engine 11 or debug.Now, ignition lock 6 does not need to close, and gear on-off should be placed in neutral.
5, when electrokinetic cell electric power storage wretched insufficiency
When possessing charge condition, electrokinetic cell 2 can be charged first external 220V alternating current, after electric power storage is more sufficient, operates vehicle again.If do not possessed charge condition, gear on-off can be placed in neutral, operation driving engine Auxiliary control switch 8 is in enable position, auxiliary starter 10 start the engine 11, ignition lock 6 closes, traveling of putting into gear (can only hang forward gear advance to travel), driving engine 11 drives running car by simple planetary arrangement 20, main reduction gear 22, diff 23, and driving mode is the same.As traveling of reversing gear will be hung, because driving engine during reverse travel 11 must be deactivated.Therefore, certain electricity must be had at electrokinetic cell 2 could move backward.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
