PROBLEM TO BE SOLVED: To provide a rear wheel steering control device which controls a rear wheel steering device for steering right and left rear wheels of a vehicle independently, and can prevent, in advance, the behavior of the vehicle from being unstable due to occurrence of unexpected steering.SOLUTION: A rear wheel steering control device 130 controls a rear wheel steering device for steering right and left rear wheels independently by actuators 14 and 15, and comprises: a rotation angle detector 33L for detecting a rotation angle of the actuator 14; an absolute position detector 34L for detecting an absolute position of the actuator 14; and an electronic control device 13L for controlling the actuator 14 according to a steering command value. The electronic control device 13L includes: an abnormality processing unit 55 for monitoring the steering command value, the rotation angle, or the absolute position, and detecting an unexpected steering state; and a power interruption unit 54a for interrupting a drive power source 61, which applies drive power to the actuator 14, when the unexpected steering state is detected.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、意図しない転舵が発生し、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130は、左右の後輪をアクチュエータ14,15によりそれぞれ独立に転舵する後輪転舵装置を制御し、アクチュエータ14の回転角を検出する回転角検出器33Lと、アクチュエータ14の絶対位置を検出する絶対位置検出器34Lと、転舵指令値に従ってアクチュエータ14を制御する電子制御装置13Lとを備える。電子制御装置13Lは、転舵指令値と、回転角または絶対位置とを監視して意図しない転舵状態を検知する異常処理部55と、意図しない転舵状態を検知したとき、アクチュエータ14に駆動電力を与える駆動電源61を遮断する動力遮断部54aとを有する。【選択図】 図4
