The invention discloses an abrupt slope slow descent control method for a pure electric logistics vehicle in the field of abrupt slope slow descent control of the pure electric logistics vehicle, which comprises combined keys and a control module, the combined keys comprise an activation key, a cancel key, a vehicle speed increase key and a vehicle speed decrease key, and the control module comprises a vehicle controller and a motor controller. And the whole vehicle controller is connected with the motor controller. Aiming at the working condition that a driver needs to frequently step on a brake pedal to achieve speed reduction under the road condition that the vehicle runs on the steep slope for a long time, the invention provides a control method for slowly descending the steep slope by introducing an energy recovery mechanism, and when the vehicle speed reaches a driving intention value of the driver, the driver only needs to press an activation key to start a steep slope slow descending function, so that the vehicle speed is reduced. The vehicle can run at a constant speed at a set vehicle speed only by stepping on the vehicle, so that brake pad abrasion, heating and personnel fatigue caused by frequent brake stepping are reduced, downhill energy can be recycled, and the driving safety and the energy efficiency economy are improved.

    本发明公开了纯电动物流车的陡坡缓降控制领域的一种纯电动物流车陡坡缓降控制方法,包括组合按键和控制模块,组合按键包括激活键、取消键、车速加按键和车速减按键,控制模块包括整车控制器和电机控制器,整车控制器与电机控制器互连。本发明针对在车辆处于长下陡坡行驶的路况下,需要驾驶员频繁的踩制动踏板实现减速的工况,提供一种引入能量回收机制来进行陡坡缓降的控制方法,当车速达到驾驶员意图行驶的值时,驾驶员只需按下激活按键,启动陡坡缓降功能,就能在设定的车速下匀速行驶,这不仅减少了频繁踩刹车导致的制动片磨损、发热、人员疲劳,也有助于下坡能量的回收利用,提高驾驶安全性和能效经济性。
