Integrative control strategy of regenerative and hydraulic braking for hybrid electric car

Abstract

Since electric braking involvement, the braking system of an EV, HEV and FCV becomes much more complex than conventional mechanical alone braking system. The target in this hybrid braking system is to recover the braking energy as much as possible and meanwhile maintain a good braking performance for vehicle safety. For this purpose, the control of this braking system is very crucial. In this paper, a integrative braking control strategy has been developed and simulation model has been established, by which the braking performance has been validated, that includes energy recovering, braking feel and braking safety etc..
