Abstract The structure and working principle of an electro-hydraulic hybrid brake system for electric vehicles were introduced simply. The regenerative braking control strategy of the conventional friction brake system and the influence of the electro-hydraulic brake (EHB) system on the braking energy recovery capability of electric vehicles were discussed. Through characteristics that enable the EHB system to precisely control the braking process of electric vehicles, a theoretical conclusion that friction braking force is distributed to a non-drive shaft to maximize regenerative braking was established. A regenerative braking control strategy based on this conclusion was designed. A simulation research, which verified the effectiveness of the regenerative braking control strategy, was conducted in ADVISOR2002. Result shows that the control strategy can improve the rates of braking energy recovery and effective energy recovery in electric vehicles compared with the traditional parallel brake distribution control strategy.

Key words： automobile engineering electro-hydraulic brake (EHB) system braking force distribution electro-hydraulic hybrid brake system regenerative braking control strategy
