The invention relates to the field of new energy vehicles, and particularly discloses a hybrid electric vehicle braking energy recovery method and a hybrid electric vehicle. According to the hybrid electric vehicle braking energy recovery method provided by the invention, whether the vehicle can enter a mechanical braking mode or not can be judged according to the brake pedal position, the batterySOC and the vehicle speed; on the premise of not meeting the requirement of entering a mechanical braking mode, whether the required braking force is less than a motor braking force limit value and less than the maximum motor braking force or not is judged; and if the condition is met, an electric braking mode is entered, or otherwise, a hybrid braking mode is entered, and different braking modesare entered according to different judgment conditions, so that the braking energy is recovered to the maximum extent, the recovery efficiency of the braking energy is improved, and normal use of a user is not influenced.

    本发明涉及新能源汽车领域,具体公开了一种混合动力汽车制动能量回收方法及混合动力汽车。本发明提供的混合动力汽车制动能量回收方法可以根据制动踏板位置、电池SOC和车速判断汽车是否可以进入机械制动模式,在不符合进入机械制动模式的前提下,判断需求制动力是否小于电机制动力限值且小于最大电制动力,如果符合条件,则进入电制动模式,否则进入混合制动模式,根据不同的判断条件进入不同的制动模式,以实现最大限度的回收制动能量,提高制动能量的回收效率,且不影响用户的正常使用。
