The deficiencies in the prior art.
Summary of the invention
The present invention is directed to alleviate the status that exploitation hybrid vehicle cost of investment is high, the R&D cycle is long in the prior art,
And the method for considering that existing traditional front-engine rear-drive internal-combustion engines vehicle repacks hybrid vehicle into is less, cannot embody
The effect of the obvious fuel-economizing of hybrid vehicle proposes that a kind of traditional front-engine rear-drive internal-combustion engines vehicle repacks hybrid vehicle into
The dynamical system of original orthodox car had both been utilized in method, and under the premise of increasing a small amount of component, had good fuel-economizing effect
Fruit, the feature that repacking is quick, control is simple.
In order to solve the above technical problems, the present invention is achieved by the following technical scheme:
A kind of method that tradition front-engine rear-drive internal-combustion engines vehicle repacks hybrid vehicle into, the component of installation includes electric power storage
Pond, power coupler, motor, hybrid controller (HCU), electric machine controller (MCU), power source management controller (BMS), institute
