The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
As shown in Figure 1, automobile hybrid power drive system described in the utility model mainly comprises the front-wheel 5 and trailing wheel 10 of driving engine 1, ISG motor 2, change speed gear box 3, ISG electric machine controller 6, electrokinetic cell 7, wheel hub motor 8, hub motor control device 9 and automobile.Wherein, driving engine 1 links to each other with ISG motor 2 room machines, ISG motor 2 links to each other with change speed gear box 3 machineries again, change speed gear box 3 is a 6AT change speed gear box, and 6AT change speed gear box 3 is connected on front-wheel 5 axle drive shafts, in machinery space, be provided with ISG electric machine controller 6, on the two-wheeled of trailing wheel 10, be respectively equipped with wheel hub motor 8, above-mentioned wheel hub motor 8 is respectively with after a hub motor control device 9 links to each other, link to each other with above-mentioned ISG electric machine controller 6 again, be provided with electrokinetic cell 7 below car floor, electrokinetic cell 7 links to each other with ISG electric machine controller 6, hub motor control device 9 respectively.
Said structure makes that the wheel hub motor 8 on the collocation trailing wheel 10 drove, and forms the four-wheel hybrid drive system when vehicle kept traditional front-wheel 5 driving engines 1 to drive.
The utility model is realized the method for above-mentioned four-wheel hybrid drive system:
The motoring condition of vehicle reduces three major types: mild motoring condition, and the limping state, state gives it the gun.
Under the level and smooth motoring condition, as travel in the urban district, the vehicle drive force demand is little, adopts pure motorized motions that is wheel hub motor 8 to drive, and reduces disposal of pollutants.When the ECU (Electrical Control Unit) of vehicle breaks down, when promptly vehicle entered the limping state, hub motor control device 9 stopped the work of wheel hub motor 8, Body control module ECU control driving engine 1 independent drive.When vehicle in climbing or when quickening, the high-performance driving of demand, at this moment, driving engine 1 and wheel hub motor 8 drive jointly.
In the vehicle ' process, ISG motor 2 is in three kinds of mode of operations: idle running, generating and driving.When driving engine 1 had power more than needed, ISG motor 2 absorbed a part of power and generates electricity to electrokinetic cell 7 chargings; When the propulsive effort demand of vehicle surpassed driving engine 1 tolerance range, ISG motor 2 was in driving condition, satisfying the demand of travelling of vehicle, and wheel hub motor 8 work simultaneously, realize driving jointly; Vehicle drive force demand and driving engine 1 power that provides balance each other or electrokinetic cell 7 when being in saturation conditions, and ISG motor 2 neither drives and also do not start, and is in idling conditions.
In the process of car retardation braking, release the gas pedal is gently stepped on brake pedal, and 6AT change speed gear box 3 has been realized the cut-out of driving engine 1 power automatically, and the 8 counter-rotating generatings of hub motor control device 9 control wheel hub motors give electrokinetic cell 7 chargings, realize that braking energy reclaims.
When the vehicle Parking, in running order with the driving engine 1 that ISG motor 2 machineries link to each other, driving engine 1 drives 2 work of ISG motor, the driving energy converts electric energy to through ISG motor 2 and delivers to electrokinetic cell 7 storages, realize the Parking charging of vehicle, in addition, also can realize external charge by external 220V power supply.
