The invention discloses a vehicle speed control method and device, terminal equipment and a storage medium, and relates to the field of automatic driving. The method comprises the steps that the current acceleration, the current speed and the current driving torque of a vehicle are obtained; according to the current speed and a preset target speed, based on a preset acceleration conversion rule, performing conversion to obtain a target acceleration; calculating according to the current speed, the target speed, the current acceleration, the current driving torque and vehicle entity attribute information to obtain a current required total torque; and controlling the current acceleration to the target acceleration according to the current required total torque until the current speed reaches the target speed. The problem of overshoot of vehicle speed control is solved.

    本申请公开了一种车辆速度控制方法、装置、终端设备以及存储介质,涉及自动驾驶领域,其方法包括:获取车辆的当前加速度、当前速度和当前驱动扭矩;根据所述当前速度和预设的目标速度,基于预设的加速度换算规则,换算得到目标加速度;根据所述当前速度、所述目标速度、所述当前加速度、所述当前驱动扭矩和车辆实体属性信息进行计算,得到当前所需总扭矩;根据所述当前所需总扭矩,控制所述当前加速度至所述目标加速度,直到所述当前速度达到所述目标速度。本发明解决了车辆速度控制的超调问题。
