The invention discloses a downhill road section auxiliary braking method, controller and system. The method comprises steps of starting monitoring of a service braking signal when a vehicle runs on a downhill road section; controlling a first auxiliary brake and/or a second auxiliary brake to be started according to the sequence of the monitored service braking signals during the period of monitoring the service braking signals so as to carry out auxiliary braking on the service braking, and starting monitoring on the service acceleration signals; during the period of monitoring the driving acceleration signal, when the driving acceleration signal is monitored, the first auxiliary brake and/or the second auxiliary brake in the opening state being controlled to be closed. According to the method, the downhill road section can be automatically recognized, opening and closing of the engine brake and/or the retarder brake can be controlled according to the braking behavior and the acceleration behavior of the driver, the running speed of the vehicle on the downhill road section can be controlled, and even if the service brake fails, safety of the driver can be ensured through an auxiliary braking method.

    本发明公开了一种下坡路段辅助制动方法、控制器及系统,所述方法包括:当车辆行驶在下坡路段时,开启对行车制动信号的监测;在监测行车制动信号期间,根据监测到行车制动信号的次序控制第一辅助制动器和/或第二辅助制动器开启,以对行车制动进行辅助制动,并开启对行车加速信号的监测;在监测行车加速信号期间,当监测到行车加速信号时,控制处于开启状态的第一辅助制动器和/或第二辅助制动器关闭。本发明能够自动识别下坡路段,根据驾驶员的制动行为和加速行为,控制发动机制动器和/或缓速器制动器的开启和关闭,控制车辆在下坡路段的行驶速度,即使行车制动器失效,也能够通过辅助制动的方法确保驾驶员的安全。
