The invention relates to the technical field of electric vehicle control, in particular to a vehicle speed control method and device, an electric vehicle, a storage medium and a program product.The method comprises the steps that the actual vehicle speed of the electric vehicle under the maximum vehicle speed working condition is obtained; the actual required torque of the electric vehicle is obtained according to the actual vehicle speed; and calculating an adjustment value of a driving motor of the electric vehicle according to the actual demand torque and the target demand torque, and performing output adjustment on the driving motor according to the adjustment value, so that the actual demand torque is consistent with the target demand torque, and a target vehicle speed corresponding to the maximum vehicle speed working condition is achieved. Therefore, the problems that in the related technology, when the accelerator of the electric vehicle is full, fluctuation of rising and falling of the battery temperature is not considered, so that discharging power fluctuates, the vehicle speed is not smooth, and the requirement for vehicle speed stability cannot be met are solved, and when the electric vehicle is under different regional road conditions, the vehicle speed of the electric vehicle is controlled within a safe range is not considered. And therefore, the safety is relatively poor, and the like.
本申请涉及电动汽车控制技术领域,特别涉及一种车速控制方法、装置、电动汽车、存储介质及程序产品,其中,方法包括:获取电动汽车处于最高车速工况时的实际车速;根据实际车速得到电动汽车的实际需求扭矩;根据实际需求扭矩和目标需求扭矩计算电动汽车的驱动电机的调整值,并根据调整值对驱动电机进行输出调整,以使实际需求扭矩与目标需求扭矩一致,达到最高车速工况对应的目标车速。由此,解决了相关技术中,没有考虑电动汽车满油门时,电池温度会出现上升下降的波动,使得放电功率波动,导致车速不平顺,无法满足车速稳定的要求,也没有考虑在电动汽车处于不同地区道路条件时,将电动汽车的车速控制在安全范围内,导致其安全性较差等问题。
