하이브리드 왯지 브레이크 개발

An electronic wedge brake (EWB) uses the wedge principle to provide a self-reinforcement mechanism, resulting in reduced power to the actuation motor. However, EWB needs mechanical device for adjust of pad wear, even if EWB need a extra equipment in order to compensate adjust of pad wear, and it has disadvantage that braking force can not be occurred and controled if CAN or supplied power are disconnected. The hEWB has fast response and mechanical backup using wedge mechanism and hydraulic system when the hEWB is failed. In this study, hEWB with a proposed structure is designed and developed and the braking performance of the proposed hEWB was verified using test rig and vehicle testing.
