In the present invention, a rear wheel steering control device which performs independent steering of left and right rear wheels controls a rear wheel steering device for independently steering the left and right rear wheels and has a pair of electronic control devices (13L, 13R) for respectively controlling a pair of left and right actuators (14L, 14R) of the rear wheel steering device (12). The rear wheel steering control system is provided with: the rear wheel steering control device; a connection switching unit (31) for alternately switching the connections of the steering motors (25L, 25R), rotation angle sensors (26L, 26R), and absolute position detectors (27L, 27R) of the pair of actuators (14L, 14R) to the pair of electronic control devices (13L, 13R); an abnormality determination part (32) for detecting an occurrence of abnormality in either one of the pair of electronic control devices (13L, 13R); and an abnormality handling control part (33) which, when the occurrence of an abnormality is detected, causes the connection switching unit (31) to perform the switching operation. |
