To provide a vehicle and a vehicle speed detector with which it is possible to detect the speed of the vehicle on the basis of the speed of a wheel that can reflect the true speed of the vehicle.SOLUTION: A vehicle 1 includes wheels 3. A vehicle speed detector 10 mounted in the vehicle 1 comprises a turning direction detection unit 11, a wheel speed acquisition unit 12, an inner outer wheel speed conversion unit 13, and a speed detection unit 14. The turning direction detection unit 11 determines the turning direction of the vehicle 1. The wheel speed acquisition unit 12 acquires the speed of each wheel 3 and then generates four wheel speed signals. The inner outer wheel speed conversion unit 13 determines, on the basis of the four wheel speed signals and the turning direction signal, which of the left and right wheels is an inner wheel and an outer wheel. The speed detection unit 14 determines on the basis of information from the inner outer wheel speed conversion unit 13, whether being less than or equal to a prescribed threshold, generates a speed of the vehicle 1 closer to true and realizes improvement of the accuracy of controlling the vehicle position.SELECTED DRAWING: Figure 5

    【課題】車両の真の速度を反映し得る車輪の速度に基づいて車両の速度を検出できる車両および車両速度検出装置を提供する。【解決手段】車両1は、車輪3を備える。車両1に搭載される車両速度検出装置10は、旋回方向判定部11と、車輪速度取得部12と、内外輪速度変換部13と、速度検出部14とを備える。旋回方向判定部11は車両1の旋回方向を判定する。車輪速度取得部12は、各車輪3の速度を取得した上で、四つの車輪速度信号を生成する。内外輪速度変換部13は、四つの車輪速度信号と旋回方向信号に基づき、左右の車輪のどちらが内輪、外輪になるかを判定する。速度検出部14は、内外輪速度変換部13からの情報に基づき所定の閾値以下か否かを判定して車両1のより真に近い速度を生成して、車両位置の制御精度の向上を実現する。【選択図】図5
