To provide a turning system provided with an electric turning mechanism and a hydraulic turning mechanism and configured to precisely control turning angles of left wheels and right wheels.SOLUTION: A turning system of the present invention is configured such that a torsion bar is engaged via a steering gear box (hereinafter, abbreviated simply as a gear box) with a turning shaft and that portions at the upstream of the torsion bar from the gear box are rotated by an electric motor, and hydraulic pressure is applied by a hydraulic turning mechanism. Therefore, left wheels and right wheels are turned. In the turning system of the present invention, turning angles of the left wheels and the right wheels are controlled by controlling the electric motor. Meanwhile, the electric motor is controlled by friction force of the turning system including an electric turning mechanism and the hydraulic turning mechanism and based on road surface reaction force. Consequently, the tuning angles of the left wheels and the right wheels can be appropriately controlled.SELECTED DRAWING: Figure 1

    【課題】電動転舵機構と液圧転舵機構とを備えた転舵システムにおいて、左側車輪と右側車輪との転舵角を精度よく制御することである。【解決手段】本転舵システムにおいては、トーションバーがステアリングギヤボックス(以下、単にギヤボックスと略称する)を介して転舵軸に係合させられ、電動モータにより、トーションバーのギヤボックスより上流側の部分が回転させられ、液圧転舵機構により、転舵軸に液圧が加えられる。それにより、左側車輪と右側車輪とが転舵させられる。本発明の転舵システムにおいては、電動モータの制御により左側車輪と右側車輪との転舵角が制御されるのであるが、電動モータが、電動転舵機構と液圧転舵機構とを含む転舵機構の摩擦力と、路面反力とに基づいて制御される。それにより、左側車輪と右側車輪との転舵角を良好に制御することができる。【選択図】 図1
