Abstract

The invention discloses a braking system of an electronic hand brake and a control method thereof and aims at overcoming the problems that a speed changing rod is locked when a gear-P parking system of a speed changing box perform parking on a slope, the speed changing box is damaged in the running process due to misoperation after the a gear P is engaged and a pure electric vehicle is not parked and accordingly slides on the slope when being charged. The braking system of the electronic hand brake comprises an EPB button (10), an EPB electronic controller (5), a rear left brake (11) and a rear right brake (12). The EPB button (10) is in wired connection with a lead 1, a lead 2, a lead 3 and a lead 4 of a button identification chip (9) in the EPB electronic controller (5) through a signal wire SW1, a signal wire SW2, a signal wire SW3 and a signal wire SW4 sequentially, and a motor driving circuit (8) in the EPB electronic controller (5) is connected with a rear left motor (13) and a rear right motor (14) through cables sequentially. The invention further provides the control method of the braking system of the electronic hand brake.

Description

technical field

[0001] The invention relates to an automobile brake system, more precisely, the invention relates to an electronic hand brake system and a control method thereof. Background technique

[0002] Now that vehicles are developing towards electronic intelligence, the electronic handbrake braking system realizes the handbrake function of traditional vehicles through buttons. With the popularization of automatic transmission vehicles, vehicles equipped with automatic transmissions will have P gear locks. When the position of the shift control handle is placed in this gear position, the parking lock mechanism will lock the transmission output shaft, so the drive shaft is locked in the gearbox. The inner quilt is partially locked, and the vehicle also has a certain braking force when the brakes are not stepped on on flat ground. However, if the vehicle stops on a slope, if the vehicle only locks the drive shaft by the P lock in the automatic transmission, the weight ...
