The invention discloses a vehicle speed control method and device, a vehicle and a storage medium, and relates to the technical field of new energy vehicle control. The method comprises the steps that when a vehicle is in a vehicle speed limiting state, whether the current speed limiting value of the vehicle at the current moment is equal to the previous speed limiting value of the vehicle at the previous moment or not is determined; if yes, the current request torque is determined based on the previous request torque of the vehicle at the previous moment, the current speed of the vehicle and the current speed limit value; if not, determining a current request torque based on the current acceleration and the target acceleration of the vehicle; and controlling the speed of the vehicle based on the current request torque. According to the technical scheme, the vehicle speed control precision and the vehicle stability can be improved.
本申请公开了一种一种车辆速度控制方法、装置、车辆及存储介质,涉及新能源汽车控制技术领域。其中,该方法包括:当车辆处于车速限制状态时,确定车辆在当前时刻的当前限速值和上一时刻的上一限速值是否相等;若相等,则基于车辆在上一时刻的上一请求扭矩、车辆的当前车速和当前限速值确定当前请求扭矩;若不相等,则基于车辆的当前加速度和目标加速度确定当前请求扭矩;基于当前请求扭矩控制车辆的车速。本申请提供的技术方案,可以提高车速控制精度与车辆稳定性。
