The invention discloses an EPB-based anti-lock system and an anti-lock method thereof. The EPB-based anti-lock system comprises an EPB controller, an automobile wheel speed signal source, an automobile storage battery power source, an EPB switch, a left EPB caliper and a right EPB caliper, wherein the automobile wheel speed signal source collects wheel speed signals of four wheels of an automobileand uploads the wheel speed signals to the EPB controller; the EPB controller calculates the locking degree of the rear wheel according to the wheel speed signal so as to judge the road surface condition; and the EPB controller executes a clamping force operation of the corresponding road surface on the left EPB caliper and the right EPB caliper according to different road surface conditions, andthe operation is repeated until the automobile is stopped. On the basis of an original EPB system, the anti-lock function during emergency braking is added, and the safety performance of an electronic parking system is improved.

    本发明公开了一种基于EPB的防抱死系统及其防抱死方法,包含EPB控制器、汽车轮速信号源、汽车蓄电池电源、EPB开关、左EPB卡钳和右EPB卡钳,汽车轮速信号源采集汽车四个轮子的轮速信号并上传到EPB控制器;EPB控制器根据轮速信号计算得到后轮的抱死程度从而判断路面情况;EPB控制器根据不同路面情况对左EPB卡钳和右EPB卡钳执行相对应路面的夹紧力操作,重复直至汽车停止。本发明在原EPB系统的基础上,增加了应急制动时防抱死的功能,提升了电子驻车系统体系的安全性能。
