The embodiment of the invention provides a resolver decoding redundancy processing method and device, electronic equipment and a storage medium, and relates to the technical field of electric driving systems. The method comprises the following steps: carrying out rotation speed signal verification on a received rotation speed signal to determine whether the rotation speed signal is in a normal state; after the verification is passed, converting the rotating speed signal into a first motor rotating speed; and comparing and checking the first motor rotating speed with a second motor rotating speed obtained by resolver soft decoding, and if the deviation between the two rotating speeds is within a set threshold range, determining that a rotor position signal obtained by soft decoding is in a normal state. According to the method, the soft decoding result is verified by using the rotating speed signal having the fixed mapping relationship with the rotating speed of the motor end, redundancy monitoring is realized, meanwhile, the rotating speed information of the motor can be indirectly obtained, and the problems that the rotating speed signal cannot be obtained and the reliability of the soft decoding result cannot be ensured when a fault occurs in the existing method are solved.

    本申请实施例提供一种旋变解码冗余处理方法、装置、电子设备及存储介质,涉及电驱动系统技术领域。该方法包括对接收到的转速信号进行转速信号校验,以确定所述转速信号是否处于正常状态;校验通过后,将所述转速信号换算为第一电机转速;将所述第一电机转速与旋变软解码得到的第二电机转速进行对比校验,若两者的偏差在设定阈值范围内,则软解码得到的转子位置信号处于正常状态。该方法利用与电机端转速存在固定映射关系的转速信号对软解码结果进行校验,实现冗余监控,同时可间接获得电机转速信息,解决了现有方法在故障时无法获得转速信号且无法保证软解码结果的可靠性问题。
