The invention discloses a hydraulic brake system for a three-axle automobile and a control method of the hydraulic brake system. The hydraulic brake system comprises an ECU, an electric push rod I, a brake master cylinder I, a main pipeline I, a normally-open electromagnetic valve III, a normally-open electromagnetic valve IV, a left brake wheel cylinder set and a right brake wheel cylinder set. The ECU is used for controlling the on-off of the normally open solenoid valve III and the normally open solenoid valve IV; one end of a brake master cylinder I is connected with an electric push rod I, the other end of the brake master cylinder I is connected with one end of a main pipeline I, the other end of the main pipeline I is divided into two branch pipelines I, the two branch pipelines I are connected with a left brake wheel cylinder set and a right brake wheel cylinder set in a one-to-one correspondence mode, and a normally-open electromagnetic valve III is arranged on the branch pipeline I connected with the right brake wheel cylinder set. The normally open solenoid valve IV is arranged on a branch pipeline I connected with the left brake wheel cylinder group; according to the method, a three-axle automobile is steered according to the principle of a braking type steering mechanism of a tracked vehicle; the three-axle automobile can be assisted in turning around in a narrow space, and meanwhile the three-axle automobile running normally can be braked.

    本发明公开了一种用于三轴汽车的液压制动系统及其控制方法,所述系统包括:ECU、电推杆Ⅰ、制动主缸Ⅰ、总管路Ⅰ、常开电磁阀Ⅲ,常开电磁阀Ⅳ、左制动轮缸组和右制动轮缸组;ECU用于控制常开电磁阀Ⅲ和常开电磁阀Ⅳ的通断;制动主缸Ⅰ的一端与电推杆Ⅰ连接,另一端与总管路Ⅰ的一端连接,总管路Ⅰ的另一端分成两个支管路Ⅰ,两个支管路Ⅰ分别与左制动轮缸组和右制动轮缸组一一对应连接,常开电磁阀Ⅲ设置在与右制动轮缸组连接的支管路Ⅰ上,常开电磁阀Ⅳ设置在与左制动轮缸组连接的支管路Ⅰ上;所述方法依照履带式车辆制动式转向机构原理对三轴汽车进行转向;本发明能够辅助三轴汽车能狭窄的空间内掉头,同时还能制动正常行驶的三轴汽车。
