The invention provides a braking energy recovery method, a vehicle control unit, electronic equipment and a vehicle thereof. The current vehicle speed and current operation information of a new energy vehicle are obtained in real time; if the current vehicle speed is smaller than the first preset vehicle speed, whether the current operation information meets a preset braking energy recovery condition or not is judged; if the current operation information meets the preset braking energy recovery condition, a hydraulic torque converter of the new energy automobile is closed; under the condition that the hydraulic torque converter is closed, braking energy is recycled according to the target braking energy recycling torque; wherein the target braking energy recovery torque is determined according to the braking depth of a braking pedal of the new energy automobile. The purpose of recovering the braking energy of the new energy automobile when the automobile speed is low is achieved.

    本发明提供一种制动能量回收方法、整车控制器、电子设备及其车辆,实时获取新能源汽车的当前车速和当前运行信息;若当前车速小于第一预设车速,判断当前运行信息是否满足预设制动能量回收条件;若当前运行信息满足预设制动能量回收条件,闭合新能源汽车的液力变矩器;在液力变矩器闭合的情况下,根据目标制动能量回收扭矩进行制动能量回收;其中,目标制动能量回收扭矩根据新能源汽车的制动踏板的制动深度确定。本发明以实现新能源汽车在车速较低时进行制动能量回收为目的。
