PROBLEM TO BE SOLVED: To enhance an estimation accuracy of a movement amount of a vehicle with respect to a vehicle movement amount calculation device, a vehicle movement amount calculation program and a vehicle movement amount calculation method.SOLUTION: An acquisition part 21, which acquires a curvature of a revolution locus calculated from a steering angle of a vehicle 1, a vehicle speed calculated from a pulse signal of a wheel speed sensor 5, and an angular speed calculated from an output signal of a yaw rate sensor 6, is provided. Further, an estimation part 26, which estimates a calibration value k corresponding to an aberration between a tire circumference length calculated based on a pulse signal and an actual tire rolling length and a drift amount m corresponding to an aberration between a yaw rate corresponding to an output signal and an actual yaw rate, on the basis of revolution geometric characteristic such that the product of a curvature by a vehicle speed is coincident with an angular speed, is provided.SELECTED DRAWING: Figure 3

    【課題】車両移動量算出装置,車両移動量算出プログラム及び車両移動量算出方法に関し、車両の移動量の推定精度を向上させる。【解決手段】車両1の操舵角から算出される旋回軌跡の曲率と、車輪速センサ5のパルス信号から算出される車速と、ヨーレートセンサ6の出力信号から算出される角速度とを取得する取得部21を設ける。また、曲率及び車速の積が角速度に一致する旋回幾何特性に基づき、パルス信号に基づいて算出されるタイヤ周囲長と実際のタイヤ転がり長とのずれに相当する校正量kと、出力信号に対応するヨーレートと実際のヨーレートとのずれに相当するドリフト量mとを推定する推定部26を設ける。【選択図】図3
