According to the redundant electronic hydraulic brake system, the control method and the vehicle, a hydraulic brake master cylinder and an electronic hydraulic brake unit are integrated and connected with a brake fluid oil can, and the hydraulic brake master cylinder and the electronic hydraulic brake unit are each provided with two independent and redundant cavities; a fourth chamber of a hydraulic brake master cylinder is communicated with a first chamber of an electronic hydraulic brake unit and is communicated with a first brake set through a first brake fluid pipeline, and the rest second chamber is communicated with a third chamber and is communicated with a second brake set through a second brake fluid pipeline. And the pistons in all the cavities are pushed to move so as to build hydraulic pressure corresponding to the target braking force, and the hydraulic pressure is transmitted into the corresponding brakes for braking. Redundancy can be provided for the electronic hydraulic braking system, so that normal work of the braking system of the vehicle is guaranteed, and the safety of the vehicle is effectively improved.
本发明提供的一种冗余电子液压制动系统、控制方法及车辆,该系统包括:将液压制动主缸和电子液压制动单元进行集成并与制动液油壶连接,液压制动主缸和电子液压制动单元分别设置有两个彼此独立且相互冗余的腔室,将液压制动主缸的第四腔室与电子液压制动单元的第一腔室连通并通过第一制动液管路连通第一制动器组,剩下的第二腔室和第三腔室连通并通过第二制动液管路连通第二制动器组,推动各个腔室内的活塞运动以建立与目标制动力相对应的液压力,并将液压力传入对应的制动器以进行制动。本发明能够为电子液压制动系统提供冗余,以保证车辆的制动系统正常工作,有效提升了车辆的安全性。
