The invention discloses a downhill safety control method, system and device for a pure electric bus, electronic equipment and a computer readable storage medium, and belongs to the technical field of electric buses. Comprising the steps of obtaining a downhill safety function starting signal and activating a get-off safety function; acquiring current vehicle speed information in real time, and comparing the current vehicle speed information with the lower limit vehicle speed of the active braking adjustment of the whole vehicle: if the current vehicle speed information is smaller than the lower limit vehicle speed of the active braking adjustment of the whole vehicle, outputting a driving torque or a braking torque to a motor controller according to the operation intention of a driver to control the vehicle to accelerate or decelerate; and if the current vehicle speed information is greater than the lower limit vehicle speed of the whole vehicle active braking adjustment and the opening degree of the brake pedal is not detected, entering an active braking mode, and controlling the vehicle to slow down according to the current vehicle speed information. The vehicle speed can be controlled within a reasonable and safe range, and the problem that in the prior art, the vehicle speed can only be limited by passively applying braking torque is solved.
本发明公开了一种纯电动客车下山安全控制方法、系统、装置、电子设备和计算机可读存储介质,属于电动客车技术领域。包括获取下山安全功能开启信号,激活下车安全功能;实时获取当前车速信息,将当前车速信息与整车主动制动调节的下限车速比较:若当前车速信息小于整车主动制动调节的下限车速,根据驾驶员操作意图输出驱动扭矩或制动扭矩至电机控制器以控制车辆加速或减速;若当前车速信息大于整车主动制动调节的下限车速且未检测到制动踏板有开度,进入主动制动模式,根据当前车速信息,控制车辆减速。能够将车速控制在合理且安全的范围内,解决了现有技术中存在“只能通过被动施加制动扭矩进行车速限制”的问题。
