In a motor drive system, a reaction force actuator and a steering actuator each have a plurality of control calculation units provided redundantly and a plurality of motor drive units provided redundantly. The reaction force and the control calculation units of the systems paired with each other among the steering actuators transmit and receive information to each other by means of inter-actuator communication. When any one of the two actuators has failed (S1) or when communication between the actuators of any one of the two actuators has failed (S3), the control calculation unit of each actuator of the failed system stops the motor drive control (S3). In both actuators, the motor drive control is continued by a control calculation unit of a normal system (S4).

    本发明涉及马达驱动系统,其中,反作用力致动器以及转向致动器分别具有冗余地设置的多个控制运算部以及冗余地设置的多个马达驱动部。反作用力、转向致动器中的相互成对的系统的控制运算部彼此通过致动器间通信相互收发信息。在两个致动器中的任意一个致动器中的任意一个系统中发生故障时(S1)、或者在任意一个系统的致动器间通信发生故障时,发生了故障的系统的各致动器的控制运算部停止马达驱动控制(S3)。而且,在双方的致动器中通过正常的系统的控制运算部继续马达驱动控制(S4)。
