The invention discloses auxiliary braking equipment, method and device for a semitrailer and a medium, and relates to the field of semitrailer braking. The auxiliary braking equipment of the semitrailer comprises a controller, an electric drive axle and an electric brake, the controller is connected with the electric drive axle and the electric brake and is used for sending a brake starting instruction to the electric drive axle when the state information of the tractor meets a preset condition; the electric drive axle recovers energy and brakes when receiving the brake starting instruction, and transmits the recovered electric energy to the electric brake through the controller; and the electric brake is arranged at the drive axle and used for receiving electric energy transmitted by the electric drive axle through the controller for braking. Therefore, in the technical scheme, the electric drive axle recovers energy during braking, the recovered electric energy is used for supplying power to the brake for braking, the two drive axles conduct auxiliary braking at the same time during braking, and the braking effect is improved; and meanwhile, energy is greatly saved, and the problem that auxiliary braking of the semitrailer is not economical is solved.

    本申请公开了一种半挂车辅助制动设备、方法、装置及介质,涉及半挂车制动领域。半挂车辅助制动设备包括控制器,电驱动桥和电制动器;控制器连接电驱动桥和电制动器,用于当牵引车的状态信息满足预设条件时,发送启动制动的指令至电驱动桥;电驱动桥接收到启动制动的指令时进行能量回收并进行制动,并将回收的电能通过控制器传输至电制动器;电制动器设置于驱动桥处,用于接收电驱动桥通过控制器传输的电能以进行制动。由此可见,上述技术方案中,电驱动桥通过制动时回收能量,将回收的电能供电制动器工作以进行制动,制动时两个驱动桥同时进行辅助制动,改善制动效果;同时十分的节能,解决了半挂车辅助制动不经济的问题。
