The invention discloses a 5G technology-based electric vehicle ramp driving speed optimization method. The method comprises the following steps of S1, obtaining ramp data and driving data in a vehicle driving process; s2, calculating the energy consumption of the vehicle according to the ramp data and the driving data; and S3, calculating the optimal driving force and the vehicle speed of the vehicle passing through the ramp, so that the energy consumption accumulated value of the vehicle passing through the ramp within the preset time period is the lowest. The ramp data is acquired in real time based on the 5G Internet of Things technology, and the real-time speed and driving force of the vehicle are optimized by taking the lowest energy consumption of the vehicle passing through the ramp within the predetermined time period as the target function, so that the energy consumption of the vehicle passing through the ramp is reduced; and meanwhile, the phenomena of start-stop, idling, rapid deceleration, rapid acceleration and the like of the electric vehicle on a crossing ramp are reduced, so that the vehicle passing efficiency is improved.

    本发明公开了一种基于5G技术的电动汽车坡道驾驶速度优化方法,包括以下步骤:S1,获取车辆行进过程中的坡道数据和行车数据;S2,根据所述坡道数据和行车数据计算车辆的能耗;S3,计算车辆通过坡道的最优驱动力和车速,使得车辆在预定时间段内通过坡道的能耗累计值最低。本发明基于5G物联网技术实时获取坡道数据,以车辆在预定时间段内通过坡道的最低能耗为目标函数,对车辆的实时速度和驱动力进行优化,从而降低了车辆通过坡道的能耗;同时减少了电动汽车在交坡道启停、怠速、急减速和急加速等现象,从而提高了车辆通行效率。
