VEHICLE CONTROL DEVICE

To suppress vibration in a vehicle, and to increase regeneration opportunity of a filter in a low temperature environment.SOLUTION: A control object of a vehicle control device is a vehicle 500 which includes: an internal combustion engine 10 including a filter 25 for capturing particulate substances in an exhaust gas; an automatic transmission 80 connected to the internal combustion engine 10; and a torque converter 50 interposed between the internal combustion engine 10 and the automatic transmission 80. The torque converter 50 includes a lock-up clutch 60 which switches, according to supply/discharge of a hydraulic oil, between a connected state where the internal combustion engine 10 is connected to the automatic transmission 80 and a disconnected state where the internal combustion engine 10 is disconnected from the automatic transmission 80. In the case where the temperature of the hydraulic oil is below a determination temperature, first processing for bringing the lock-up clutch 60 into the disconnected state, and second processing for performing fuel cut in the internal combustion engine 10 on a condition that the lock-up clutch 60 is in the disconnected state and the accumulation amount of the particulate substances captured by the filter 25 is equal to or greater than the determination accumulation amount, during deceleration of the vehicle 500, are executed.SELECTED DRAWING: Figure 1 【課題】車両の振動を抑え、且つ低温環境でのフィルタの再生機会を増やす。【解決手段】排気中の粒子状物質を捕集するフィルタ２５を備えた内燃機関１０と、内燃機関１０に連結している自動変速機８０と、内燃機関１０及び自動変速機８０の間に介在しているトルクコンバータ５０とを有し、トルクコンバータ５０は、作動油の給排に応じて、内燃機関１０と自動変速機８０とを接続した接続状態、又は内燃機関１０と自動変速機８０とを切り離した切断状態に切り替わるロックアップクラッチ６０を備える車両５００を制御対象とし、作動油の温度が判定温度未満の場合、ロックアップクラッチ６０を切断状態にする第１処理と、車両５００の減速中、ロックアップクラッチ６０が切断状態であり、且つフィルタ２５に捕集された粒子状物質の堆積量が判定堆積量以上であることを条件に、内燃機関１０においてフューエルカットを行う第２処理と、を実行する。【選択図】図１
