The invention relates to a vehicle speed control method and device, computer equipment and a storage medium. The method comprises the steps that the initial vehicle speed of a vehicle and the actual vehicle speed at the current moment are obtained, and when the actual vehicle speed is larger than the initial vehicle speed, the speed difference between the initial vehicle speed and the actual vehicle speed is obtained; according to the speed difference and the vehicle braking parameters, the sliding resistance difference of the vehicle is obtained; and according to the sliding resistance difference, corresponding torque is output to carry out speed reduction control on the actual vehicle speed. By adopting the method, the vehicle speed can be controlled stably when the vehicle goes downhill.

    本申请涉及一种车速控制方法、装置、计算机设备和存储介质。所述方法包括:获取车辆的初始车速和当前时刻的实际车速,当实际车速大于初始车速时,获得初始车速和实际车速之间的速度差;根据速度差与车辆制动参数,获得车辆的滑行阻力差;根据滑行阻力差,输出相应的扭矩对实际车速进行降速控制。采用本方法能够在车辆下坡时,对车速进行稳速控制。
