The invention relates to the technical field of new energy intelligent vehicles, in particular to a vehicle speed control algorithm of a new energy intelligent vehicle, which is characterized in that a closed loop of acceleration is added on the basis of vehicle speed control, the speed and the acceleration can be controlled, the vehicle speed change rate of the whole vehicle is controllable, the vehicle speed control is smoother, and the stability of the vehicle is enhanced. Acceleration is calculated through software, the speed of the vehicle is indirectly controlled by controlling the acceleration, the driving feeling can be greatly improved, meanwhile, the speed control precision can be improved through a closed loop of the speed, meanwhile, no external sensor is used, and the driving experience is improved. The method has more advantages in adaptability and cost, and can be widely applied to scenes where the vehicle speed needs to be controlled, such as low-speed creeping, dynamic vehicle speed control of an intelligent vehicle, constant-speed cruising and limping.
