To provide a vehicle about which good operability is acquired when traveling by maintaining present speed.SOLUTION: A vehicle comprises: a mode control unit which is capable of switching to a first travel mode in which torque changes by following a drive operation and a second travel mode which performs travel which is closer to inertia travel than the first travel mode; a target torque calculation unit which calculates target torque on the basis of the drive operation; a first indication torque calculation unit which calculates indication torque which follows the target torque by adding a first variation limit in the first travel mode; a second indication torque calculation unit which calculates the indication torque which follows the target torque by adding a second variation limit against which limit is stronger than the first variation limit after the indication torque approaches zero in the second travel mode; and a drive control unit which drives a power source or a brake unit so that the calculated indication torque is outputted to a drive wheel.SELECTED DRAWING: Figure 3 【課題】現状の速度を維持して走行する場合に、良好な運転操作性が得られる車両を提供する。【解決手段】車両は、運転操作に追従してトルクが変化する第１走行モードと、第１走行モードよりも惰性走行に近い走行を行う第２走行モードとに切り替え可能なモード制御部と、運転操作に基づき目標トルクを算出する目標トルク算出部と、第１走行モードにおいて第１変化量制限を加えて目標トルクに追従する指示トルクを算出する第１指示トルク算出部と、第２走行モードにおいて指示トルクをゼロに近づけた後に第１変化量制限よりも制限が強い第２変化量制限を加えて目標トルクに追従する指示トルクを算出する第２指示トルク算出部と、算出された指示トルクが駆動輪に出力されるように動力源又は制動部を駆動する駆動制御部とを備える。【選択図】図３
