The present disclosure relates to an electro-hydraulic brake. The electro-hydraulic brake includes: a wheel brake configured to supply braking force to wheels of a vehicle; an accumulator for storing brake oil; a master cylinder connected to the reservoir and cooperating with the master brake motor to generate a pressure of brake oil; a first controller configured to control the main brake motor; a hydraulic controller including a pump configured to form a pressure of the brake oil in cooperation with the auxiliary brake motor, and a hydraulic block configured to selectively transmit the pressure of the brake oil formed in the master cylinder or the pump to the wheel brake; and a second controller configured to control the auxiliary brake motor when a failure occurs in the master cylinder or the first controller. The hydraulic controller is provided with an auxiliary flow path to transfer brake oil directly from the reservoir to the pump through the auxiliary flow path.
本公开涉及一种电动液压制动器。电动液压制动器包括:车轮制动器,其被构造成向车辆的车轮供应制动力;储液器,其存储制动油;主缸,其连接到储液器,并且与主制动马达协同操作以产生制动油的压力;第一控制器,其被构造成控制主制动马达;液压控制器,其包括泵和液压块,该泵被构造成与辅助制动马达协同地形成制动油的压力,该液压块被构造成将制动油的形成在主缸或泵中的压力选择性地传递到车轮制动器;以及第二控制器,其被构造成当主缸或第一控制器发生故障时控制辅助制动马达。液压控制器设置有辅助流动路径,以穿过辅助流动路径将制动油从储液器直接传输到泵。
