The invention discloses an EPS steering motor stalling protection method, and relates to the technical field of motor control. The technical key points are as follows: firstly, the locked-rotor working condition of the motor is identified according to the current angular speed of a motor rotor and the current of a motor bus, secondly, misjudgment signals are filtered out through a confirmation link, and then the speed of reducing the bus current is determined by combining the working conditions of a whole vehicle and a steering system. The method has the advantages that the accuracy and rationality of locked-rotor identification can be improved, and the robustness of a steering system during locked-rotor protection is improved.
本发明公开了一种EPS转向电机堵转保护方法,涉及电机控制的技术领域。其技术要点是:首先是根据当前电机转子角速度和电机母线电流,来识别电机的堵转工况,其次通过确认环节过滤掉误判信号,然后结合整车、转向系统工况,决定降母线电流的速率。本发明具有的优点:可以提高堵转识别的准确性、合理性,并提高堵转保护时,转向系统的鲁棒性。
