The invention provides a brake-by-wire device with safety redundancy and a using method. The brake-by-wire device comprises a first electric cylinder unit, a second electric cylinder unit, an oil can, a central control unit, a hydraulic control unit and a wheel cylinder. The first set of electric cylinder unit is connected with the oil pot and the hydraulic control unit, the second set of electric cylinder unit is connected with the oil pot and the hydraulic control unit, and the hydraulic control unit is connected with the wheel cylinder; the central control unit is connected with the first electric cylinder unit, the second electric cylinder unit, the oil can and the hydraulic control unit. According to the braking system of the unmanned tool car, when part of the main braking system fails or all of the main braking system fails or braking force is insufficient, the standby braking system is started immediately and continues to complete braking independently or cooperatively, and the reliability problem and potential safety hazards possibly existing in the unmanned tool car are solved.

    本发明提供了一种具备安全冗余的线控制动装置及使用方法,包括:第一套电动缸单元、第二套电动缸单元、油壶、中央控制单元、液压控制单元以及轮缸;所述第一套电动缸单元连接所述油壶和所述液压控制单元,所述第二套电动缸单元连接所述油壶和所述液压控制单元,所述液压控制单元连接所述轮缸;所述中央控制单元连接所述第一套电动缸单元、所述第二套电动缸单元、所述油壶以及所述液压控制单元。本申请提供一种无人驾驶工具车的制动系统,当主制动系统部分失效,或全部故障,或制动力不足时,备用制动系统随即启动,继续独立或协同完成制动,解决无人驾驶工具车可能存在的可靠性问题和安全隐患。
