The invention discloses a vehicle downhill energy recovery method, device and equipment and a medium. The method comprises the steps of calculating a change parameter integration value and a convergence variance at a current moment according to an obtained change parameter integration value and a convergence variance at a previous moment and collected vehicle real-time collection data at the current moment when it is determined that a vehicle stably travels downhill; when it is determined that a convergence condition is met according to the change parameter integration value at the current moment and the convergence variance, determining the change parameter integration value at the current moment as a target integration value; calculating a target torque according to the target integration value and vehicle real-time acquisition data at the current moment; and controlling the energy recovery strength according to the target torque. The embodiment of the invention can improve the adaptability of vehicle downhill energy recovery.

    本发明公开了一种车辆下坡能量回收方法、装置、设备及介质。该方法包括:在确定车辆平稳下坡行驶时,根据获取的上一时刻的变化参数整合值、收敛方差和采集的当前时刻的车辆实时采集数据,计算当前时刻的变化参数整合值和收敛方差;在根据当前时刻的变化参数整合值和收敛方差,确定满足收敛条件时,将当前时刻的变化参数整合值确定为目标整合值;根据目标整合值和当前时刻的车辆实时采集数据,计算目标扭矩;根据目标扭矩控制能量回收力度。本发明实施例可以提高车辆下坡能量回收的适应性。
