PROBLEM TO BE SOLVED: To provide a vehicle ground speed detection device capable of accurately detecting ground speed even during revolving time.SOLUTION: A vehicle ground speed detection device 50 comprises: a wheel speed sensor 24 for detecting rotation speed v of wheels 5, 8; second storage means 58 for storing radii of the wheels 5, 8 corresponding to a bank angle; and ground speed calculation means 60 for calculating the ground speed V during revolving time. The ground speed calculation means 60 extracts the radii of the wheels 5, 8 corresponding to the bank angle detected by a bank angle detection device 20, from the second storage means 58, then, calculates the ground speed V during revolving time, based on the extracted radii of the wheels 5, 8 and the rotation speed v of the wheels 5, 8 detected by the wheel speed sensor 24.SELECTED DRAWING: Figure 3
【課題】旋回時であっても、対地速度を精度よく検出することができることができる車両の対地速度検出装置を提供する。【解決手段】車両の対地速度検出装置50は、車輪5,8の回転速度vを検出する車輪速センサ24と、バンク角に対応する車輪5,8の半径を記憶した第2記憶手段58と、旋回時の対地速度Vを算出する対地速度算出手段60とを備えている。対地速度算出手段60は、バンク角検出装置20で検出されたバンク角に対応する車輪5,8の半径を第2記憶手段58から抽出し、抽出された車輪5,8の半径と車速センサ24で検出された車輪5,8の回転速度vから旋回時の対地速度Vを算出する。【選択図】図3
