The invention provides a redundant braking system of a semi-trailer tractor and a working method of the redundant braking system, and relates to the technical field of vehicle braking. The system comprises a first vehicle control unit, an electronic braking system, a second vehicle control unit, an electronic parking braking system and a trailer valve. Wherein the first vehicle control unit is used for controlling the electronic braking system to brake the tractor and the trailer; the second vehicle control unit is used for controlling the electronic parking braking system and the trailer valve to brake the tractor and the trailer under the condition that the electronic braking system breaks down. In the embodiment, the original vehicle electronic parking brake system EPB is used as the redundant brake of the electronic brake system EBS, so that the redundant brake can be provided when the brake of the electronic brake system EBS fails, and the driving safety is effectively improved.
本发明提供一种半挂牵引车的冗余制动系统及其工作方法,涉及车辆制动技术领域。该系统包括:第一整车控制器、电子制动系统、第二整车控制器、电子驻车制动系统和挂车阀;其中,第一整车控制器用于控制电子制动系统进行牵引车及挂车的制动;第二整车控制器用于在电子制动系统发生故障的情况下,控制电子驻车制动系统及挂车阀进行牵引车及挂车的制动。上述实施例中利用原车电子驻车制动系统EPB作为电子制动系统EBS的冗余制动,从而在电子制动系统EBS制动失效时也可以提供冗余制动,有效地提高行车安全。
