The invention provides brake actuation with redundancy based on electronic stability control. The brake system includes an electronic stability control (ESC) module defining a first interconnected channel and a pressure supply unit (PSU) module defining a second interconnected channel in fluid communication with the first interconnected channel. The ESC module includes a first pump configured to transfer brake fluid from the PSU module and to the plurality of wheel brakes, and a launch valve configured to selectively control fluid communication between the first interconnection passage and an inlet of the first pump. The PSU module includes a second pump configured to transfer brake fluid from the fluid storage to the first interconnection passage, and a bypass fluid passage from the fluid storage to the ESC module having a through check valve that allows fluid to flow from the fluid storage through the bypass fluid passage and to the ESC module while preventing fluid from flowing in the opposite direction.
本发明提供一种基于电子稳定性控制的具有冗余的制动部致动。制动系统包括限定了第一互连通道的电子稳定性控制(ESC)模块和限定了与第一互连通道流体连通的第二互连通道的压力供应单元(PSU)模块。ESC模块包括被配置成将制动流体从PSU模块传输并传输到多个车轮制动部的第一泵,以及被配置成选择性地控制第一互连通道与第一泵的入口之间的流体连通的起动阀。PSU模块包括被配置成将制动流体从流体储存部传输到第一互连通道的第二泵,以及具有直通止回阀的从流体储存部到ESC模块的旁路流体通道,直通止回阀允许流体从流体储存部流过旁路流体通道并流到ESC模块,同时阻止流体沿相反方向流动。
