Component meet it is counter drag engine needed for revolving speed, torque etc., i.e., the stand-by motor of optional more small dimension reduces cost, meanwhile,
Convenient for design layout, keep layout more reasonable；
4, when vehicle launch, clutch is in discrete state, is driven with main drive motor, driving vehicle to engine
Can be in the speed that high-efficiency and economic area works, stand-by motor pre-actuates engine and intervenes it in high-efficiency and economic area speed
Driving realizes that in parallel mix is moved, and gradually main drive motor can be replaced to drive, and can greatly reduce oil consumption, greatly save cost；
5, main drive motor supplement power difference guarantees that power does not interrupt when system shift, mentions during engine gear
Rise the comfort driven；
6, traditional reverse gear is removed, can be realized and reverses gear by main drive motor reversing；
7, in the case where main drive motor works independently, as battery pack electricity is lower than certain setting value, stand-by motor
Start engine, engine start to efficient economic zone directly drives active motor by stand-by motor power generation or fills for battery pack
Electricity, when start under dead ship condition for battery pack supplement electricity；
8, it when vehicle braking, is recovered energy, is avoided energy waste by main drive motor；
9, engine can work on any gear, realize large range of intervention, suitable for more complicated works
Condition；
10, for stand-by motor when engine parallel connection interventional systems work, can produce load makes engine approach colleges and universities as far as possible
Area's work, and the load generated can be used for generating electricity, it is more energy efficient；
11, acceleration, heavy grade starting demand large torque are defeated in special operation condition, such as suddenly for first embodiment and second embodiment
Fashionable, main drive motor exports in insufficient situation, and stand-by motor can be cooperated by shafting and main drive motor；
12, this system is more compact, light-weight, small in size, is conducive to vehicle carrying.
To mitigate total quality, the solid shafting occurred in the utility model embodiment can be substituted with hollow shaft.
