The Research of Regenerative Braking Control Strategy for Advanced Braking Force Distribution

Regenerative braking system is the characteristic system of electric and hybrid electric vehicle. The system can restore the kinetic energy and potential energy, used during start and accelerating, into battery through electrical machine. A control strategy witch is based on ideal braking force distribution is proposed. Front wheel and rear wheel can make full use of ground adhesion condition with the strategy when the vehicle brakes. More regenerative braking energy is reclaimed on the premise of ensuring braking efficiency. A simulation model is built in ADVISOR, and then put in vehicle model to simulate. The result proves that more effective braking energy is reclaimed and vehicle fuel economy is improved.
