Abstract
Under the background of the development of new energy vehicles, the traditional three major parts of vehicles change with the change of energy supply. The traditional hydraulic brake can no longer adapt to today's electro-mechanical system, and the EMB system has become the inevitable direction of the development of the brake system. The current closed-loop control system of the EMB design is not fully developed, and there is a lack of consideration for the impact of brake clearance. In this paper, a lightweight EMB braking system is designed, and key mathematical models related to it are established. The control output of braking force is optimized by the PID algorithm. At the same time, a brake clearance compensation strategy is proposed. After simulation test, the system has good braking force control performance, and reduces the incidence of motor underspeed, and the overall system has good feasibility and stability.
