To provide a two motor type hybrid all-wheel-drive vehicle which can perform regeneration by a front-wheel at the time of deceleration, and realize ideal front and rear wheel driving force distribution when shifting from EV travel, restarting an engine, to HEV travel.SOLUTION: A hybrid all-wheel-drive vehicle 1 comprises: a first clutch 42 which is mounted between a second motor generator 12 and a front wheel; and a second clutch 51 which is mounted between the second motor generator 12 and a rear wheel. HEV-CU80 makes the first clutch 42 engaged at the time of regeneration and release the second clutch 51, and makes the first motor generator 11 activate to re-start an engine 10 when shifting from EV travel by the second motor generator 12 to HEV travel, and the HEV-CU also adjusts fastening power of the first clutch 42 and the second clutch 51 and output torque of the second motor generator 12 to compensate the drive torque of the front wheel with the second motor generator 12 while keeping the drive torque of the rear wheel.SELECTED DRAWING: Figure 1 【課題】減速時に前輪で回生でき、かつ、ＥＶ走行から、エンジンを再始動してＨＥＶ走行に移る際に、理想的な前後駆動力配分を実現することが可能な２モータ式のハイブリッド全輪駆動車を提供する。【解決手段】ハイブリッド全輪駆動車１は、第２モータ・ジェネレータ１２と前輪との間に介装される第１クラッチ４２と、第２モータ・ジェネレータ１２と後輪との間に介装される第２クラッチ５１とを備える。ＨＥＶ－ＣＵ８０は、回生時に第１クラッチ４２を締結するとともに第２クラッチ５１を解放し、第２モータ・ジェネレータ１２によるＥＶ走行からＨＥＶ走行に移る際に、第１モータ・ジェネレータ１１を稼働してエンジン１０を再始動する一方、後輪の駆動トルクを維持しつつ、第２モータ・ジェネレータ１２で前輪の駆動トルクを補償するように、第１クラッチ４２、第２クラッチ５１の締結力、及び、第２モータ・ジェネレータ１２の出力トルクを調節する。【選択図】 図１
