The invention discloses a vehicle energy recovery control method and device, a vehicle control unit and a vehicle. The method comprises the steps that in the vehicle running process, whether an accelerator pedal of the vehicle is loosened or not is judged; if the accelerator pedal is released, the vehicle is controlled to enter a sliding feedback mode; judging whether a brake pedal of the vehicle is stepped down or not; if the brake pedal is stepped down, the vehicle is controlled to exit the sliding feedback mode, and the vehicle is controlled to enter a brake feedback mode; judging whether an electronic braking system (EBS) of the vehicle is intervened or not; if the EBS intervenes, the intervention torque is obtained, and the vehicle is controlled to conduct braking feedback according to the intervention torque. According to the control method for vehicle energy recovery, the sliding feedback function is added before the brake pedal of the EBS is stepped down, the battery recovery efficiency is improved, the torque at the moment of exiting the sliding feedback is latched, the torque can be smoothly transited to the EBS intervention torque, the torque change amplitude is reduced, and the vehicle energy recovery efficiency is improved. And the comfort in the vehicle braking process is improved.

    本发明公开了一种车辆能量回收的控制方法、装置、整车控制器和车辆,所述方法包括:车辆行驶过程中,判断车辆的油门踏板是否被松开;若油门踏板被松开,则控制车辆进入滑行回馈模式;判断车辆的制动踏板是否被踩下;若制动踏板被踩下,则控制车辆退出滑行回馈模式,并控制车辆进入制动回馈模式;判断车辆的电子制动系统EBS是否干预;若电子制动系统EBS干预,则获取干预扭矩,并根据干预扭矩控制车辆进行制动回馈。本发明的车辆能量回收的控制方法根据电子制动系统EBS在制动踏板被踩下之前,增加滑行回馈功能,提高了电池回收效率,并且对退出滑行回馈时刻的扭矩进行锁存,使扭矩能够平缓地过渡到EBS干预扭矩,减少扭矩变化幅度,提高车辆制动过程舒适性。
