The invention relates to a vehicle speed control method and related equipment, and the method comprises the steps: responding to a vehicle speed control instruction, and obtaining a real-time operation parameter and an expected vehicle speed of a vehicle; obtaining the request torque of the vehicle based on the real-time operation parameters and the expected vehicle speed; the real-time feedback torque of the vehicle is obtained; based on the real-time feedback torque and the request torque, the target output torque of the vehicle is obtained; and controlling the speed of the vehicle based on the target output torque to enable the vehicle to reach the expected speed. The problems that in the prior art, the braking mode of reducing the vehicle speed through friction force between a brake pad and wheels and finally stopping the vehicle depends on physical friction, and although the braking mode is effective, abrasion and energy consumption of the vehicle are increased to a certain degree are solved.

    本申请涉及一种车辆的速度控制方法及相关设备,方法包括:响应于车速控制指令,获取车辆的实时运行参数和期望车速;基于实时运行参数和期望车速,得到车辆的请求扭矩;获取车辆的实时反馈扭矩;基于实时反馈扭矩和请求扭矩,得到车辆的目标输出扭矩;基于目标输出扭矩对车辆进行速度控制,以使车辆达到期望车速。解决了现有技术中通过刹车片与车轮之间的摩擦力来降低车速并最终使车辆停止的制动方式依赖于物理摩擦,虽然有效,但在一定程度上增加了车辆的磨损和能耗的问题。
