전동식 브레이크를 위한 제어 알고리즘 개발

Abstract

The brake-by-wire(BBW) system, which is also called the EMB(Electro-Mechanical Brake) system, has become a promising vehicle braking control scheme. Mathematical models for the electromechanical brake and electronic wedge brake are derived, including nonlinearities such as backlash and friction in mechanical connections and clearance between the brake disk and pad. Simplified mathematical models in contact and non-contact phases are then derived from the models of the brake-by-wire systems. These simplified models are used to design the status monitoring and clamping force control algorithm without additional sensors.
