Development of an Electrically Driven Intelligent Brake System

This paper presents an electrically driven intelligent brake system that has been developed for electric vehicles and hybrid electric vehicles, which are expected to penetrate markets rapidly amid the ongoing energy paradigm shift. This brake system achieves a cooperative energy regeneration function and high responsiveness while providing braking performance, system reliability and vehicle mounting ease equal to that of conventional brake systems with a vacuum booster. This paper outlines the newly developed brake system and describes various issues involved in cooperative regenerative braking along with the technologies that were applied to address them.
