To provide a vehicle weight estimation device and a vehicle capable of appropriately estimating vehicle weight even when a driving force is transmitted to a driving wheel without passing through a driving force transmission device such as a clutch.SOLUTION: When step-in operation, in which the opening degree changes by the amount of change equal to or larger than a threshold, is performed on an accelerator pedal, a motor control part 102 causes a motor 11 to generate a first torque, which is a compensation torque for compensating the inertia moment of an electric vehicle 1 added to the torque corresponding to the opening degree. In a vehicle weight estimating part 103, a driving torque and acceleration at a first time point during acceleration of the electric vehicle 1 by the first torque are used for estimation of weight.SELECTED DRAWING: Figure 3
【課題】駆動力がクラッチ等の駆動力伝達装置を介さずに駆動輪に伝えられる場合でも、好適に車重を推定することができる車重推定装置および車両を提供する。【解決手段】モータ制御部102は、アクセルペダルに対して開度が閾値以上の変化量で変化する踏み込み操作がなされた場合に、電気自動車1の慣性モーメントを補償する補償トルクを、開度に対応したトルクに加えた第1トルクをモータ11に発生させ、車重推定部103は、第1トルクによる電気自動車1の加速中の第1時点における駆動トルクおよび加速度を重量の推定に用いる。【選択図】図3
