The invention relates to the field of automobiles, and in particular relates to a vehicle speed control method, system and device and a storage medium. Vehicle speeds and accelerator opening degrees corresponding to a vehicle at multiple moments are obtained, a vehicle speed change value is obtained through calculation according to the multiple vehicle speeds, and a first accelerator opening degree change value is obtained through calculation according to the multiple accelerator opening degrees; when the multiple vehicle speeds are all larger than the preset vehicle speed, the vehicle speed change value is smaller than the preset vehicle speed change value, and the first accelerator opening degree change value is smaller than the first preset accelerator opening degree change value, the vehicle speed corresponding to the last moment in the multiple moments is determined to be the set vehicle speed, and the vehicle is in the stable vehicle speed state; the vehicle speed corresponding to the last moment in the multiple moments is determined as the set vehicle speed, an engine is controlled to work to drive the vehicle to run according to the set vehicle speed, the situation that oil consumption is increased due to the fact that a driver repeatedly feeds and reduces oil is avoided, and fatigue caused by the fact that the driver continuously adjusts the opening degree of an accelerator is avoided.

    本发明涉及汽车领域,具体涉及本发明提供的一种车速控制方法、系统、装置及存储介质,通过获取车辆在多个时刻对应的车速和油门开度,依据多个车速计算得到车速变化值,依据多个油门开度计算得到第一油门开度变化值,当多个车速均大于预设车速、车速变化值小于预设车速变化值、以及第一油门开度变化值小于第一预设油门开度变化值,则确定多个时刻中最后一个时刻对应的车速为设定车速时,则汽车处于车速稳定的状态,确定多个时刻中最后一个时刻对应的车速为设定车速,控制发动机工作带动车辆按照设定车速行驶,避免了驾驶员反复给油和减油导致的油耗的增加,以及避免了因驾驶员不断调节油门开度导致的疲惫。
