The invention discloses an energy recovery control method and system of a vehicle and the vehicle. The energy recovery control method of the vehicle comprises the steps that under the condition that an accelerator pedal is not stepped down, the current gear of the vehicle is obtained; determining the sliding energy recovery torque according to the gears, wherein the sliding energy recovery torque of the low gear is smaller than the sliding energy recovery torque of the high gear; the brake pedal opening degree of the vehicle is obtained, the brake energy recovery torque is obtained according to the brake pedal opening degree and the gears, and under the condition that the brake pedal opening degrees are the same, the brake energy recovery torque of the low gear is larger than the brake energy recovery torque of the high gear; and controlling the vehicle to perform energy recovery according to the sliding energy recovery torque and the braking energy recovery torque. By the adoption of the method and device, the energy recovery efficiency is improved, meanwhile, the vehicle running smoothness is improved, and the good driving experience is achieved.

    本申请公开了一种车辆的能量回收控制方法、系统及车辆。车辆的能量回收控制方法,包括:在油门踏板未被踩下的情况下,获得车辆当前的档位;根据档位确定出滑行能量回收扭矩,低档位的滑行能量回收扭矩小于高档位的滑行能量回收扭矩;获得车辆的制动踏板开度,并根据制动踏板开度和档位,得到制动能量回收扭矩,制动踏板开度相同的情况下,低档位的制动能量回收扭矩大于高档位的制动能量回收扭矩;根据滑行能量回收扭矩和制动能量回收扭矩,控制车辆进行能量回收。采用本申请,提升了能量回收效率的同时,提升了车辆行驶的平顺性,具有好的驾驶体验。
