<p>PROBLEM TO BE SOLVED: To reliably prevent a steering wheel-overridden phenomenon caused by an abnormal engagement of a coupling device.SOLUTION: First through third control devices 353, 363, 393 include a control part having, as steering functional modes, at least a steer-by-wire control mode where a coupling device 4 is in a separation state, and an assist control mode where the coupling device 4 is in a coupling state. In a case where information that the coupling device 4 is in the coupling state is obtained by an information obtainment part despite that a separation instruction to separate the coupling device 4 is output, the control part switches the steering functional mode from the steer-by-wire control mode to the assist control mode.</p> |
