The invention discloses an electric control type hydraulic braking system for a trailer, the system comprises a tractor storage battery for supplying power to the system; a brake anti-lock controller used for acquiring the average wheel speed of a tractor; a wheel speed sensor which acquires the average wheel speed of the trailer; a trailer brake used for providing trailer braking force; and a hydraulic adjusting module used for adjusting the braking force of the trailer brake according to a set strategy by comparing the average wheel speed of the trailer with the average wheel speed of the tractor under the condition of receiving the braking signal. A mode of comparing the average wheel speed of the trailer with the average wheel speed of the tractor is adopted to judge whether a trailer brake wheel cylinder needs to be pressurized, pressurized or depressurized; the control is conducted in a hydraulic mode through a set strategy, the braking safety is high, and the usability is good.
本发明公开一种用于挂车的电控式液压制动系统,包括:牵引车蓄电池,为系统供电;制动防抱死控制器,获取牵引车平均轮速;轮速传感器,获取挂车平均轮速;挂车制动器,提供挂车制动力;液压调节模块,在收到制动信号情况下,通过比较挂车平均轮速和牵引车平均轮速的大小,按照设定策略调节挂车制动器的制动力大小。本发明采用比较挂车平均轮速与牵引车平均轮速的方式,来判断是需要对挂车制动轮缸进行增压、保压还是减压;采用液压方式通过设定策略进行控制,制动安全性高、使用性好。
