Abstract

The invention provides an anti-lock braking system and a control method thereof. The anti-lock braking system is connected with a first sensor and comprises an execution mechanism HCU, a first sensor, a second sensor and a control unit, and the execution mechanism HCU comprises a pressure increasing valve, a pressure reducing valve, an energy accumulator, a pump and a motor; an electronic control unit (ECU); the second sensor is used for detecting the speed of wheels and sending a speed signal to the electronic control unit ECU, the first sensor is used for detecting the braking state of the braking handle and sending information of the braking state of the braking handle to the electronic control unit ECU, and when it is judged that the braking handle is changed into the braking state, the first sensor is used for detecting the braking state of the braking handle and sending information of the braking state of the braking handle to the electronic control unit ECU. The ECU applies a first preset voltage to the pressure reducing valve; when it is judged that the slip value of the vehicle is within the first preset value range and the wheel deceleration is larger than the first threshold value, the ECU applies a second preset voltage to the pressure reducing valve, the average value of the first preset voltage applied between the moment of starting to apply the first preset voltage and the moment of starting to apply the second preset voltage is smaller than the second preset voltage.

Description

technical field [0001] The present invention relates to the technical field of vehicle control management, in particular, to an anti-lock braking system (Antilock Brake System, ABS) and a control method thereof. Background technique [0002] With the development of technology, the speed of motor vehicles is getting faster and faster, and the requirements for braking systems are also getting higher and higher. Anti-lock braking systems have been widely used in vehicles. Most of the existing anti-lock braking systems include an actuator HCU (Hybrid Control Unit), an electronic control unit ECU (Electronic Control Unit), and wheel speed sensors. Electronic control unit ECU Based on the detection value of the wheel speed sensor, determine whether the wheel is about to lock, and control the actuator HCU when the wheel is about to lock. Specifically, the electronic control unit ECU detects that the wheel is about to lock when the wheel speed sensor is about to lock. , the electro...
