The invention provides a vehicle speed limiting control method and device, a readable storage medium and a vehicle. The method comprises the steps that the maximum allowable acceleration and the whole vehicle resistance torque of the vehicle are obtained; the maximum available torque is determined according to the maximum allowable acceleration and the whole vehicle resistance torque; and determining the actual output torque according to the maximum available torque and the actual demand torque. The maximum available torque required by vehicle speed limiting is obtained by setting the maximum allowable acceleration of the vehicle, and the actual output torque is determined according to the maximum available torque and the actual required torque, so that the vehicle speed of the vehicle is limited within the target speed range; the vehicle speed of the vehicle is limited by setting the maximum allowable acceleration of the vehicle, the torque response is smooth, the vehicle speed control is more stable, the control strategy is more convenient, the resource consumption and the time consumption are reduced, and the applicability of the data among different vehicle types is higher.

    本发明提出一种车辆限速控制方法、装置、可读存储介质及车辆,该方法包括:获取车辆的最大允许加速度及整车阻力扭矩;根据最大允许加速度和整车阻力扭矩确定最大可用扭矩;根据最大可用扭矩和实际需求扭矩确定实际输出扭矩。本发明通过设置车辆最大允许加速度,得到车辆限速所需的最大可用扭矩,并根据最大可用扭矩与实际需求扭矩确定实际输出扭矩,以将车辆的车速限制在目标速度范围内,相较于PID限度扭矩,通过设置车辆最大允许加速度实现车辆的车速的限制,其扭矩响应平顺,车速控制更加稳定,控制策略更加便捷,减少资源消耗与时间消耗,其数据在不同车型之间的适用性更高。
