The invention discloses a fault limp control method for a hybrid electric vehicle, which comprises the following steps that: a vehicle control unit judges the fault type according to the detected high-voltage power-off fault information of the vehicle, and then controls the power output mode of the vehicle according to the high-voltage fault type so as to realize the slow running of the vehicle in the fault state. The method has the advantages that the high-voltage power-off faults of the whole vehicle are classified and processed, the vehicle is controlled to run slowly through the limp state in the non-emergency faults, a user is reminded to pull over conveniently by cooperating with an instrument, it is guaranteed that the vehicle is pulled over in time in the high-voltage power-off faults, and the safety of the vehicle and a driver is guaranteed; and the rationality of high-voltage power failure control is improved.

    本发明公开了一种混合动力汽车故障跛行控制方法,包括,整车控制器根据检测到车辆高压下电故障信息判断故障类型,然后根据高压故障类型控制车辆动力输出的方式以实现车辆在故障状态下的缓慢行驶。本发明的优点在于:对整车高压下电故障进行分类处理,在非紧急故障时通过跛行状态来控制车辆缓慢行车,配合仪表提醒方便用户靠边停车,保证了在高压下点故障下及时的将车辆靠边,保证了车辆及驾驶人员的安全,提高了高压下电故障控制的合理性。
