The invention discloses a vehicle speed control method and device, electronic equipment and a readable storage medium. The vehicle speed control method comprises the steps that the current torque, the current vehicle speed and the current acceleration of a vehicle are obtained; acquiring target acceleration of the vehicle according to the current vehicle speed; wherein the current vehicle speed and the target acceleration have a mapping relation; under the condition that the current acceleration value is greater than the target acceleration value, calculating a difference value between the target acceleration and the current acceleration; calculating a torque reduction value according to the acceleration difference value; determining a target torque according to the current torque and the torque reduction value; and the current torque is reduced to the target torque, so that the current vehicle speed is controlled to be below the preset maximum driving vehicle speed. Compared with the prior art that the vehicle speed is limited by limiting the maximum torque, the technical scheme can be executed under the condition that the torque is smaller than the maximum torque, the vehicle speed is adjusted, and therefore the vehicle can be controlled to run below the maximum vehicle speed more accurately.

    本申请公开了一种车速控制方法、装置、电子设备以及可读存储介质,该车速控制方法包括:获取车辆的当前扭矩、当前车速以及当前加速度;根据当前车速获取车辆的目标加速度;其中,当前车速和目标加速度存在映射关系;在当前加速度数值大于目标加速度数值的情况下,计算目标加速度和当前加速度的差值;根据加速度差值计算出扭矩减小值;根据当前扭矩和扭矩减小值确定目标扭矩;将当前扭矩减小到目标扭矩,以控制当前车速在预设的行驶最高车速以下。相对现有技术中通过限制最大扭矩限制车速,本申请的技术方案在扭矩小于最大扭矩的情况下也可以被执行,调整车速,从而可以更准确的控制车辆在行驶最高车速以下行驶。
