To improve the gripping detection accuracy while suppressing the increase of a weight of a steering wheel to be installed and the increase of facility costs in a gripping detection device for a vehicle steering wheel.SOLUTION: A gripping detection device 10 for a vehicle steering wheel 1 includes a light projection unit 11, a light receiving unit 12, and a control unit 13. The light projection unit 11 is installed at a steering switch 6 provided at a boss 2 to project light 20 toward a grip 5. The light receiving unit 12 is installed at the steering switch 6 to receive reflected light 30 of the light 20 projected from the light projection unit 11. The control unit 13 determines whether or not a driver grips the grip 5 on the basis of an output of the light receiving unit 12.SELECTED DRAWING: Figure 2

    【課題】車両用ステアリングの把持検出装置において、その設置対象となるステアリングの重量の増加や設備コストの増加を抑制しながら、把持検出の精度向上を図る。【解決手段】車両用ステアリング1の把持検出装置10は、投光部11と、受光部12と、制御部13と、を備えている。投光部11は、ボス2に設けられるステアリングスイッチ6にグリップ5へ向けて光20を投光するように設置される。受光部12は、ステアリングスイッチ6に投光部11から投光された光20の反射光30を受光するように設置される。制御部13は、受光部12の出力に基づいてグリップ5を運転者が把持しているか否かを判定する。【選択図】図2
