The invention provides a vehicle running speed control method and system, a controller, a medium and a vehicle. The vehicle running speed control method comprises the steps that the mass of a controlled vehicle and the mass of a trailer are obtained; determining the speed limit rate of the controlled vehicle based on the quality of the controlled vehicle and the trailer quality; adjusting a preset vehicle speed limit value of the controlled vehicle based on the speed limit rate to obtain a maximum vehicle speed adjustment limit value; and determining a maximum vehicle speed limit value based on the maximum vehicle speed adjustment limit value, and controlling the current maximum vehicle speed of the controlled vehicle based on the maximum vehicle speed limit value. According to the method, the maximum driving speed of the vehicle with the trailer is limited, so that the safety of the vehicle is greatly improved, and normal driving of the vehicle is guaranteed.

    本申请提供了一种车辆行驶速度的控制方法、系统、控制器、介质和车辆,其中的车辆行驶速度的控制方法包括:获取被控车辆质量和拖车质量;基于所述被控车辆质量和所述拖车质量确定所述被控车辆的限速率;基于所述限速率调整所述被控车辆的预设车速限值,得到最高车速调整限值;基于所述最高车速调整限值确定最高车速限值,基于所述最高车速限值控制所述被控车辆当前行驶的最高车速。该方法通过对带拖车车辆行驶最高车速进行限制,从而大大地提高了车辆的安全性,保证了车辆的正常行驶。
