The invention provides a brake system with redundant design and a control method thereof. The brake system with the redundant design comprises a liquid storage tank; a wheel cylinder; the main brake unit comprises a first hydraulic driving unit and a plurality of control valves, and the liquid storage tank supplies brake liquid to the main brake unit; the redundant brake unit comprises a second hydraulic driving device and a plurality of redundant control valves, the main brake unit is connected with the redundant brake unit through a first hydraulic pipeline to a fifth hydraulic pipeline, and the redundant brake unit is connected with a wheel cylinder and can supply brake fluid to the wheel cylinder; and the electronic control unit is used for controlling the first hydraulic driving device of the main braking unit, the control valves of the main braking unit, the second hydraulic driving device of the redundant braking unit and the redundant control valves of the redundant braking unit, so that different braking states of the braking system are realized.

    本发明提供一种冗余设计的制动系统及其控制方法。该冗余设计的制动系统包括:储液罐;轮缸;主制动单元,该主制动单元包括第一液压驱动单元以及多个控制阀,并且储液罐向主制动单元提供制动液;冗余制动单元,该冗余制动单元包括第二液压驱动装置以及多个冗余控制阀,主制动单元经由第一液压管路至第五液压管路与冗余制动单元相连接,冗余制动单元与轮缸相连接,能够将制动液提供给所述轮缸;以及电子控制单元,该电子控制单元对主制动单元的第一液压驱动装置、主制动单元的多个控制阀、冗余制动单元的第二液压驱动装置及冗余制动单元的多个冗余控制阀进行控制,从而实现制动系统的不同制动状态。
