description To curb generation of a shock due to abrupt engagement of a lock-up clutch while preventing degradation of energy efficiency when a vehicle travels with drive force output from an engine and an electric motor.SOLUTION: When drive force is output from an engine and an electric motor, a lock-up clutch control section makes an increment in torque capacity of the lock-up clutch with respect to a difference between an actual slip amount and a target slip amount due to feedback control in slip control of the lock-up clutch smaller than the same when the drive force is output only from either the engine or the electric motor. Thus, a vehicle control device can prevent the torque capacity of the lock-up clutch from becoming excessively large without stopping the slip control even when the difference between the actual slip amount and the target slip amount is increased. Accordingly, the vehicle control device can curb generation of a shock due to abrupt engagement of the lock-up clutch while preventing degradation of energy efficiency when the vehicle travels with drive force output from the engine and the electric motor.SELECTED DRAWING: Figure 2 【課題】エンジン及び電動機から駆動力を出力して走行するときに、エネルギー効率の悪化を抑制しつつ直結クラッチの急係合によるショックの発生を抑制する。【解決手段】直結クラッチ制御部により、エンジン及び電動機から駆動力が出力されるときには、エンジンのみから駆動力が出力されるときと、電動機のみから駆動力が出力されるときと、の各々に比べて、直結クラッチのスリップ制御におけるフィードバック制御による、スリップ量の実際値と目標値との差に対する直結クラッチのトルク容量の増加分が小さくされるので、スリップ制御が停止されることなく、スリップ量の実際値と目標値との差が大きくなっても直結クラッチのトルク容量の過多が抑制される。よって、エンジン及び電動機から駆動力を出力して走行するときに、エネルギー効率の悪化を抑制しつつ直結クラッチの急係合によるショックの発生を抑制することができる。【選択図】図2
