PROBLEM TO BE SOLVED: To provide an output control device for a vehicle which is capable of preventing a quick start after passing over a step without deteriorating operability of the vehicle after passing over the step.SOLUTION: When a vehicle speed is a first predetermined vehicle speed or less, an inclination and a travel start torque Ts are calculated to determine the presence or absence of a step (S10-S16). Then, a quick acceleration torque Ta is calculated to determine whether the vehicle has passed over the step (S18, S20). A torque upper limit value Tu is calculated, and the actuation of a motor 21 is controlled on the basis of a required torque Tr and the torque upper limit value Tu (S22, S24). Then, the torque upper limit value Tu is released when the vehicle has traveled a predetermined distance after passing over the step (S26, S28). 【課題】本発明は段差乗り越え後の車両の運転性を悪化することなく、段差乗り越え後の急発進を防止することのできる車両用出力制御装置を提供する。【解決手段】車速が第１所定車速以下であると、勾配と走行開始トルクＴsを算出し、段差の有無を判別する(S10-S16)。そして、急加速トルクＴaを算出して、車両が段差を乗り越えたか、否かを判別する(S18,S20)。トルク上限値Ｔuを算出し、要求トルクＴrとトルク上限値Ｔuとに基づき、モータ２１の作動を制御する(S22,S24)。そして、段差の乗り越え後、車両が所定距離を走行すると、トルク上限値Ｔuを解除する(S26,S28)【選択図】図２
