To provide a vehicle control device which can efficiently reduce the generation of noise and vibration.SOLUTION: A vehicle control device (500) comprises a control part (100) for calculating first target torque (TQx) related to first drive torque which is distributed on the basis of requirement torque after calculating the requirement torque (TQ) required by a driver by obtaining information related to a drive state of a vehicle from a sensor group, second target torque (TQy) related to second drive torque, and an ideal change rate of the total torque of the first drive torque and the second drive torque, and controlling magnitudes of the first drive torque and the second drive torque. The control part performs first zero-cross processing when the first drive torque is switched in positive torque and negative torque while the first drive torque straddles zero, and performs second zero-cross processing when the second drive torque is switched in positive torque and negative torque while the second drive torque straddles zero after the first zero-cross processing is finished.SELECTED DRAWING: Figure 3 【課題】異音や振動の発生が効率的に低減可能な車両制御装置を提供すること。【解決手段】車両制御装置(500)は、センサ群から車両の運転状態に関する情報を入手してドライバが要求する要求トルク(TQ)を算出したうえで、要求トルクに基づいて分配される第１の駆動トルクに関する第１目標トルク(TQx)及び第２の駆動トルクに関する第２目標トルク(TQy)と、第１の駆動トルク及び第２の駆動トルクの合計トルクの理想変化率と、を演算して、第１の駆動トルク及び第２の駆動トルクの大きさを制御する制御部(100)を具備し、制御部は、第１の駆動トルクがゼロを跨いでトルク正負が切り替わる際、第１のゼロクロス処理を実行し、第２の駆動トルクがゼロを跨いでトルク正負が切り替わる際、第２のゼロクロス処理を、前記第１のゼロクロス処理が完了した後に実行するものである。【選択図】 図３
