To provide a vehicle position detection device capable of detecting the position of a vehicle on the basis of the rotation speed information of an axle and correcting the detected position of the vehicle without needing a ground side facility.SOLUTION: A vehicle position detection device 1 includes a position detection unit 11 for detecting the position of a vehicle on the basis of the rotation speed information of an axle, a position estimation unit 12 for inputting a satellite positioning system signal and speed related information (speed, acceleration) of the vehicle in each unit time to successively estimate the position of the vehicle, and a propriety determination unit 13 for determining the propriety of position correction, and corrects a detection position by the position detection unit 11 on the basis of an estimated position by the position estimation unit 12 in accordance with a determination result of the propriety determination unit 13.SELECTED DRAWING: Figure 2
【課題】車軸の回転数情報に基づいて車両の位置を検知するとともに、地上側設備を必要とすることなく、検知された車両の位置を補正することのできる車両位置検知装置を提供する。【解決手段】車両位置検知装置1は、車軸の回転数情報に基づき車両の位置を検知する位置検知部11と、衛星測位システム信号及び前記車両の速度関連情報(速度、加速度)を単位時間毎に入力して前記車両の位置を逐次的に推定する位置推定部12と、位置補正の可否を判定する可否判定部13と、を含み、可否判定部13の判定結果に応じて、位置検知部11による検知位置が位置推定部12による推定位置に基づき補正される。【選択図】図2
