To provide a weight estimation device for a vehicle which can enhance the accuracy of estimation of vehicle weight which is to be registered.SOLUTION: A weight estimation device 100 for a vehicle 10 detects a drive force and an acceleration of the vehicle 10 in a prescribed period, detects the vehicle drive force, the acceleration and a road surface gradient in the prescribed period, estimates the weight of the vehicle 10 on the basis of the detected drive force and the acceleration. When a specific condition indicating that the accuracy of the estimation of the estimated weight of the vehicle 10 is higher than the accuracy of the estimation of the registered weight of the vehicle 10 holds, the weight estimation device changes the registered weight of the vehicle to the estimated weight of the vehicle 10 on the basis of the drive force and the acceleration of the vehicle 10 which were detected in the prescribed period.SELECTED DRAWING: Figure 2

    【課題】登録される車両重量の推定の精度を高めることができる車両重量推定装置を提供する。【解決手段】車両10の重量推定装置100は、所定の期間における車両10の駆動力および加速度を検出するとともに所定の期間における車両駆動力と加速度と路面勾配とを検出し、検出した駆動力および加速度に基づいて車両10の重量を推定し、推定した車両10の重量の推定の精度が登録されている車両10の重量の推定の精度よりも高いことを示す特定条件が成立している場合、登録されている前記車両の前記重量を、所定の期間に検出された車両10の駆動力および加速度に基づいて推定した車両10の重量に変更する。【選択図】図2
