The invention discloses a self-adaptive vehicle weight energy recovery method, system and device and a storage medium, and the method comprises the steps: obtaining the no-load mass and the load weight of a target vehicle, and determining the real-time vehicle load of the target vehicle according to the no-load mass and the load weight; the real-time vehicle speed of the target vehicle is obtained, and the real-time sliding resistance of the target vehicle is determined according to the real-time vehicle speed and the real-time vehicle load; inputting the real-time vehicle load, the real-time vehicle speed and the real-time sliding resistance into a pre-trained brake recovery torque prediction model to obtain a target brake recovery torque; and performing energy recovery control on the target vehicle according to the target braking recovery torque. According to the method, the influence of the vehicle load, the vehicle speed and the sliding resistance on the braking recovery torque under different vehicle working conditions is considered, the accuracy of energy recovery control is improved, the energy recovery efficiency of the vehicle in the sliding stage is improved, the driving experience and the riding experience of a user are improved, and the method can be applied to the technical field of vehicle control.

    本发明公开了自适应车重的能量回收方法、系统、装置及存储介质,包括:获取目标车辆的空载质量和装载物重量,根据空载质量和装载物重量确定目标车辆的实时车辆负载;获取目标车辆的实时车辆速度,根据实时车辆速度和实时车辆负载确定目标车辆的实时滑行阻力;将实时车辆负载、实时车辆速度以及实时滑行阻力输入到预先训练好的制动回收扭矩预测模型,得到目标制动回收扭矩;根据目标制动回收扭矩对目标车辆进行能量回收控制。本发明考虑了不同车辆工况下车辆负载、车辆速度以及滑行阻力对制动回收扭矩的影响,提高了能量回收控制的准确性,从而提高了车辆滑行阶段能量回收的效率,也提高了用户的驾驶体验和乘车体验,可应用于车辆控制技术领域。
