The electronic mechanical brake (EMB) system is a critical actuator for achieving
brake-by-wire control. This review categorizes and summarizes the literature
related to EMB into three sections: actuator, mathematical modeling, and control
strategies. In the actuator aspect, this article compares and analyzes motors,
motion conversion mechanisms, and self-reinforcing mechanisms. For mathematical
modeling, this article reviews modeling methods for EMB systems concerning
motors, transmission mechanisms, friction, contact collisions, nonlinear
stiffness, and hysteresis characteristics. Regarding control strategies, this
article consolidates methods for clamp force control, clamp force estimation,
and gap management. Finally, the article discusses potential future research
directions in EMB from both hardware structure and software algorithm
perspectives.
