The invention relates to the field of automobile transmission, in particular to a motor locked-rotor prevention control method under EPB and AVH working conditions. In the case that an EPB (AVH) is triggered, if the request torque of a user is smaller than the hill-holding torque of the EPB, the request torque of the user is limited to prevent large-torque stalling of the motor; if the user continues to request for larger driving torque, when the driving torque is larger than the hill-holding torque of the EPB, limitation of the request torque is released, the request torque of the user is output; and due to the fact that the request torque is larger than the hill-holding torque of the EPB, a vehicle can break through the EPB, can successfully start on the slope. The problem of large-torque stalling under the EPB (AVH) working condition is effectively solved.
本发明涉及汽车传动领域,具体涉及一种EPB和AVH工况下电机防堵转控制方法。在EPB(AVH)触发的情况下,如果用户的请求扭矩小于EPB的驻坡扭矩,就限制用户的请求扭矩,防止电机大扭矩堵转,如果用户继续请求更大的驱动扭矩,当驱动扭矩大于EPB的驻坡扭矩,就放开请求扭矩的限制,输出用户请求扭矩,由于请求扭矩大于EPB的驻坡扭矩,车辆会冲开EPB,成功坡起。本发明有效的解决EPB(AVH)工况下的大扭矩堵转问题。
