To provide a hub unit with turning function which can improve a vehicle operation stability, a turning system, and a vehicle comprising the hub unit with turning function.SOLUTION: A hub unit 1 with turning function comprises: a hub unit body 2 having a hub bearing which supports a wheel; a unit support member 3 which is provided on an undercarriage component of a suspension device, and so supports the hub unit body 2 as to be rotatable around a turning axis which extends in a vertical direction; an actuator 5 for turning which rotationally drives the hub unit body 2 around the turning axis. This hub unit further comprises turning angle detection means which detects a rotation angle around the turning axis of the hub unit body 2. The turning angle detection means comprises: an angle sensor Sa which directly detects a turning angle; a rotation sensor Sb which indirectly detects a turning angle from a rotation angle of a motor 26; and a position sensor Sc which indirectly detects a turning angle from a position of a direct-acting output part in a direct-acting mechanism.SELECTED DRAWING: Figure 3
【課題】車両の操縦・安定性を向上させることができる転舵機能付きハブユニット、転舵システム、および転舵機能付きハブユニットを備えた車両を提供する。【解決手段】この転舵機能付きハブユニット1は、車輪を支持するハブベアリングを有するハブユニット本体2と、懸架装置の足回りフレーム部品に設けられ、ハブユニット本体2を上下方向に延びる転舵軸心回りに回転自在に支持するユニット支持部材3と、ハブユニット本体2を転舵軸心回りに回転駆動させる転動用アクチュエータ5とを備える。ハブユニット本体2の転舵軸心回りの回転角度を検出する転舵角度検出手段を備えた。転舵角度検出手段は、転舵角度を直接検出する角度センサSaと、モータ26の回転角度から転舵角度を間接的に検出する回転センサSbと、直動機構における直動出力部の位置から転舵角度を間接的に検出する位置センサScとを備える。【選択図】図3
