PROBLEM TO BE SOLVED: To provide a rear wheel turn control system that controls rear wheel turning devices that independently turn the left and right rear wheels of a vehicle, and that can prevent the behavior of the vehicle to become unstable when driving for a target rear wheel turn quantity is hindered with an external force such as the state of a road surface.SOLUTION: An electronic control device 130 of a rear wheel turn control system 13 includes an abnormality sensor 55a that monitors one or both of a turn command value for rear wheels which is inputted from an electronic control unit 9, and a rotation angle detected by a rotation angle detector 33L or an absolute position detected by an absolute position detector 34L, and senses an abnormal turning state under a predetermined abnormality decision rule, and turn command cancellation means 55b that cancels a turn command for the rear wheels when the abnormality sensor 55a has sensed the abnormal turning state.SELECTED DRAWING: Figure 4 |
