To provide a torque control device of a four wheel drive vehicle that allows the four wheel drive vehicle, configured so that either of front wheels and rear wheels are driven by an engine and the others of the front wheels and the rear wheels are driven by a motor, to four-wheel travel while preventing engine stall and satisfying a request of an occupant.SOLUTION: A four wheel drive vehicle comprises an engine for driving front wheels, a motor generator for driving rear wheels and a battery for supplying power to the motor generator, which further comprises a VCM for controlling engine torque and motor torque on the basis of driver request torque. The VCM, during four-wheel driving during which the vehicle travels by driving force of both of the engine and the motor generator, causes the engine to output, as engine torque, minimum torque required for rotational driving of the engine and makes the motor generator output, as motor torque, torque determined by subtracting the engine torque from the driver request torque.SELECTED DRAWING: Figure 3

    【課題】前輪及び後輪のいずれか一方をエンジンにより駆動し、前輪及び後輪のいずれか他方をモータにより駆動する四輪駆動車両において、エンジンストールを防止して、乗員の要求を満たしながら四輪駆動走行することができる四輪駆動車両を提供すること。【解決手段】前輪を駆動するエンジンと、後輪を駆動するモータジェネレータと、モータジェネレータに電力を供給するバッテリとを備えた四輪駆動車両のトルク制御装置であって、ドライバ要求トルクに基づきエンジントルクとモータトルクとを制御するVCMを備え、VCMは、エンジン及びモータジェネレータの双方の駆動力で走行する四輪駆動時に、エンジンの回転駆動に必要な最小限のトルクをエンジントルクとしてエンジンに出力させ、ドライバ要求トルクからエンジントルクを差し引いたトルクをモータトルクとしてモータジェネレータに出力させる。【選択図】図3
