<p>PURPOSE:To detect abnormality of a motor control current by providing a motor control current supervising means for detecting the motor control current in abnormality in the case that a condition of flowing the motor control current in a reverse direction to a motor control current command is continued for a predetermined time, when the motor control current command is output. CONSTITUTION:At the time of controlling a rear wheel steering angle, in a motor control current supervising means (e), at the time of generating a motor control current command based on detection by a motor control current command detecting means (c), in the case that a condition of flowing a motor control current of preset value or more in a reverse direction to the motor control current command, based on detection by a motor control current detecting means (d), is continued for a predetermined time, the motor control current is detected abnormal. Accordingly, by including whether the motor control current is in the reverse direction or not to the motor control current command in a reference of judging motor current abnormality, in the case that the motor control current is in the reverse direction relating to the motor control current command, abnormality of the motor control current can be detected.</p> |
