Abstract

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.

Description

technical field [0001] The invention relates to an anti-lock braking system and an anti-lock braking method thereof, in particular to an EPB-based anti-lock braking system and an anti-lock braking method thereof, belonging to the field of automobile parking systems. Background technique [0002] The car's parking system is an essential system in the car's braking system. The car's parking brake system can slow down or stop the car. In the traditional mechanical hand brake car parking brake system, the brake clamping force is determined by the strength of the driver's hand brake operating mechanism. There are many problems such as the driver locking the wheel due to excessive clamping force and different road conditions during emergency braking. Problems such as the clamping force of the car wheels cannot be well controlled, which may cause the car to lose the stability of straight-line driving when the wheels are locked, and dangerous phenomena such as sideslip, tail flick a...
