The invention provides an automatic brake clearance adjusting system and method for an automobile EMB. The system comprises an electronic control unit, a motor controller and a brake execution unit. The motor controller is connected with the electronic control unit and the brake execution unit. The brake execution unit is connected with wheels; the electronic control unit transmits a braking instruction to the motor controller after receiving the vehicle state information; the motor controller controls the operation of the motor through the brake execution unit; the electronic control unit monitors the brake clearance in real time by obtaining the displacement change of a roller screw nut in the brake execution unit and automatically adjusts the brake clearance through the number of forward and reverse rotation turns of an execution motor in the brake execution unit. Based on the system, the invention further provides an automatic brake clearance adjusting method for the automobile EMB. The brake clearance between the brake disc and the brake block is monitored and automatically adjusted in real time, the abrasion loss of the brake block can be monitored in real time, the remaining mileage of the brake block can be estimated, and intelligence of a brake system is achieved.

    本发明提出了一种用于汽车EMB的制动间隙自动调节系统和方法,该系统包括电子控制单元、电机控制器和制动执行单元;电机控制器分别与电子控制单元和制动执行单元连接;制动执行单元连接车轮;电子控制单元在接收到车辆状态信息后,将制动指令传输给电机控制器;电机控制器通过制动执行单元控制电机运行;电子控制单元通过获取制动执行单元中滚柱丝杠螺母的位移变化实时监测制动间隙,并通过制动执行单元中执行电机正反转圈数自动调节制动间隙。基于该系统,还提出了一种用于汽车EMB的制动间隙自动调节方法。本发明实时监测并自动调节制动盘与制动块之间的制动间隙,且可实时监测制动块磨损量估算制动块剩余里程,实现了制动系统的智能化。
