The invention provides an energy recovery method and device, a vehicle and a storage medium, and belongs to the technical field of automobiles, and the method comprises the steps: determining that a driving path where the vehicle is located has a congested road section according to map information in a vehicle driving process; according to the maximum deceleration of the vehicle and the current vehicle speed, the safety braking distance of the vehicle is determined, and the maximum deceleration of the vehicle is the deceleration determined according to the maximum energy recovery torque; target prompt information is output according to the safety braking distance, and the target prompt information is used for prompting a driver to activate the energy recovery function before the distance between the position where the vehicle is located and the starting position of the congested road section reaches the safety braking distance. In this way, the driver is prompted to brake in time, a reference position is provided for braking of the driver, the driver can control the vehicle to decelerate with the torque lower than the maximum energy recovery torque in the whole process, the situation that the torque generated in the braking process exceeds the maximum energy recovery torque is avoided, and then energy waste is avoided.

    本申请提供了一种能量回收方法、装置、车辆和存储介质,属于汽车技术领域,该方法包括:在车辆行驶的过程中,根据地图信息,确定车辆所在的行驶路径存在拥堵路段;根据车辆的最大减速度和当前车速,确定车辆的安全制动距离,车辆的最大减速度为根据最大能量回收扭矩确定的减速度;根据安全制动距离,输出目标提示信息,目标提示信息用于提示驾驶员在车辆所在的位置与拥堵路段的起始位置之间的距离达到安全制动距离之前激活能量回收功能。这样通过提示驾驶员及时制动,为驾驶员制动提供了参考位置,有利于驾驶员控制车辆全程以低于最大能量回收扭矩的扭矩控制车辆减速,从而避免在制动过程中产生的扭矩超过最大能量回收扭矩,进而避免了能量浪费。
