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

    【課題】 車両の左右の後輪をそれぞれ独立して転舵する後輪転舵装置を制御する後輪転舵制御装置において、目的の後輪転舵量が、路面状態などの外力によってその駆動を阻害された場合に、車両の挙動が不安定に陥ることを未然に防止することができる後輪転舵制御装置を提供する。【解決手段】 後輪転舵制御装置13における電子制御装置130は、電子制御ユニット9から入力される後輪の転舵指令値と、回転角検出器33Lで検出される回転角または絶対位置検出器34Lで検出される絶対位置のいずれか一方または両方とを監視して所定の異常判定規則により異常な転舵状態を検知する異常検知部55aと、異常検知部55aが異常な転舵状態を検知したとき、後輪への転舵指令を解除する転舵指令解除手段55bとを有する。【選択図】 図4
