The invention relates to a vehicle speed control method and device, a medium, equipment and a vehicle. The method comprises the steps of obtaining real-time state data of the vehicle; the real-time state data comprises real-time estimated mass, current vehicle speed, expected vehicle speed and road condition information; the road condition information comprises a current road gradient, a road adhesion coefficient and a road rolling resistance coefficient; determining a target torque based on the real-time state data; the target torque is used for adjusting the vehicle from the current vehicle speed to the expected vehicle speed. According to the technical scheme, the target torque corresponding to vehicle speed control is determined by combining the real-time estimated mass, the current vehicle speed, the expected vehicle speed and the road condition information of the vehicle, such as the real-time state data of the current road slope, the road adhesion coefficient and the road rolling resistance coefficient; the vehicle speed can be timely and accurately controlled according to different vehicle conditions and road conditions, namely, the response speed is high, and the following performance is good.

    本公开涉及车速控制方法、装置、介质、设备以及车辆,该方法包括:获取车辆的实时状态数据;实时状态数据包括实时估算质量、当前车速、期望车速以及路况信息;路况信息包括:当前道路坡度、道路附着系数以及道路滚动阻力系数;基于实时状态数据,确定目标扭矩;目标扭矩用于使车辆由当前车速调整至期望车速。本公开的技术方案中,结合车辆的实时估算质量、当前车速、期望车速以及路况信息,如当前道路坡度、道路附着系数以及道路滚动阻力系数等实时状态数据确定进行车速控制对应的目标扭矩,能够针对不同的车况路况进行车速的及时准确控制,即响应速度较快,且跟随性较好。
