The present invention provides a braking system for an autonomous vehicle, which has a hydraulic control unit of a dual pressure release device, and is mounted on a vehicle chassis frame without including a brake master cylinder; a pedal input unit and a hydraulic control unit are separated, the size and the weight are divided into two small units, flexible arrangement in a vehicle forecabin is facilitated, the pedal input unit installed on a fireproof wallboard is small in weight and smaller than a traditional vacuum booster-brake master cylinder assembly (without a vacuum booster device), the requirement for the fireproof wallboard of a thin-wall sheet metal part is low. Due to the split type structure, one side face (the left side face and the right side face) of the hydraulic valve block does not need to be tightly attached to a fireproof wallboard to be installed, one additional face of the hydraulic valve block can be used for flexibly arranging all functional module devices of the hydraulic control unit, and an electronic control unit fixed to the hydraulic control unit is installed on a vehicle chassis frame. A vehicle inertia sensor required by a vehicle body electronic stabilizing function can be integrally arranged, and the cost is reduced.
本发明提供一种用于自动驾驶车辆的制动系统,具有双压力放生装置的液压控制单元,不包含制动主缸地安装在车辆底盘框架上;踏板输入单元和液压控制单元分开,体积和重量分解成两个小单元,利于在车辆前舱中的灵活布置,安装在防火墙板上的踏板输入单元重量小,比传统真空助力器‑制动主缸总成小(无真空助力器装置),对薄壁钣金件的防火墙板要求低,分体式的构造,不需要使液压阀块的一个侧面(左侧面、右侧面)紧贴着防火墙板安装,液压阀块可以多出一个面来灵活设置液压控制单元的各功能模块装置,固定于液压控制单元上的电子控制单元安装在车辆底盘框架上,可以集成设置车身电子稳定功能所需要的车辆惯量传感器,降低成本。
