The invention relates to an electro-hydraulic brake and a control method thereof. An electro-hydraulic brake includes: a wheel brake configured to supply braking force to wheels of a vehicle; a main brake unit including an oil reservoir storing brake oil and a main cylinder configured to form a pressure of the brake oil in cooperation with the main brake motor; and a hydraulic controller including at least one pump configured to pump brake oil in cooperation with the auxiliary brake motor, and configured to selectively transmit a pressure of the brake oil formed in the master cylinder or the pump to the wheel brake. The hydraulic controller includes at least one auxiliary flow path connected at a first end thereof to the oil reservoir and at a second end thereof to the inlet of the pump to transfer hydraulic pressure from the oil reservoir directly through the at least one auxiliary flow path to the pump.
本申请涉及电动液压制动器及其控制方法。一种电动液压制动器包括:车轮制动器,其被配置为向车辆的车轮供应制动力;主制动单元,其包括存储制动油的储油器和被配置为与主制动马达协作地形成制动油的压力的主缸;以及液压控制器,其包括至少一个泵,所述至少一个泵被配置为与辅助制动马达协作地泵送制动油,并且液压控制器被配置为将形成在主缸或泵中的制动油的压力选择性地传递到车轮制动器。液压控制器包括至少一个辅助流动路径,该至少一个辅助流动路径在其第一端处连接到储油器并且在其第二端处连接到泵的入口,以将液压从储油器通过至少一个辅助流动路径直接传递到泵。
