The invention discloses a distributed brake system of an automobile. The distributed brake system is composed of a liquid storage tank, a brake pedal, a manual cylinder, an electromagnetic isolation valve, a two-position three-way valve, a pedal force sense simulation device, a pedal controller, a brake master controller, a front wheel servo brake cylinder, a rear wheel side brake/rear wheel servo brake cylinder, a sensor and a brake wheel cylinder. In the invention, the front wheel servo brake cylinder and the rear wheel side brake/rear wheel servo brake cylinder are close to the brake wheel cylinder, the pressure reduction time is short, and the brake response is fast. The pressure buildup loop of the servo brake cylinder is not provided with an electromagnetic valve, the motor is directly used for brake pressure buildup, pressure buildup is more direct, and adjustment is easy. And a plurality of executing mechanisms are arranged, so that the braking force of all the wheels can be independently controlled and adjusted. The execution structures are located on the wheel edges of the wheels, the hydraulic transmission distance is shortened, and the pressure buildup speed is increased. The hole site and cylinder body design of the servo brake cylinder can ensure that a main cylinder infusion hole is not blocked in a manpower backup mode, and the situation that manpower backup fails is avoided.

    本发明公开了一种汽车的分布式制动系统,由储液罐、制动踏板、人力缸、电磁隔离阀、两位三通阀、踏板力感模拟装置、踏板控制器、制动主控制器、前轮伺服制动缸、后轮边制动器/后轮伺服制动缸、传感器以及制动轮缸组成。本发明中,前轮伺服制动缸和后轮边制动器/后轮伺服制动缸靠近制动轮缸,减压时间短,制动响应快。伺服制动缸的建压回路中不带有电磁阀,直接使用电机进行制动建压,建压更加直接,调节简单。具有多个执行机构,使得所有车轮的制动力都可以独立控制和调节。各执行结构位于各个车轮的轮边,降低了液压传递的距离,提高建压速度。伺服制动缸的孔位和缸体设计可保证人力备份模式下主缸输液孔不堵塞,避免人力备份失效的情况。
