Provided is a vehicle control device which can improve learning accuracy in controlling a lockup clutch pressure learning and suppress a decrease in learning frequency in controlling a lockup clutch pressure learning. When control of an L/U clutch pressure learning is executed, learning accuracy in controlling the L/U clutch pressure learning can be improved by preventing a lockup matching of the L/U clutch (15) in a traveling state where an excessive variation in engine RPM (Ne) is easily generated by gear changes in a continuously variable transmission (18) during learning. Additionally, when control of the L/U clutch pressure learning is executed, in a traveling state where an excessive variation in engine RPM (Ne) is easily generated by gear changes in a continuously variable transmission (18), a decrease in learning frequency can be suppressed not only by simply preventing a lockup matching of the L/U clutch (15) but also executing a lockup matching of the L/U clutch (15) after a conversion into a traveling state where such excessive variation is not easily generated during learning. (과제) 로크업 클러치압 학습 제어의 학습 정밀도를 향상시킬 수 있고, 또한, 로크업 클러치압 학습 제어의 학습 빈도의 저하를 억제한다. (해결 수단) L/U 클러치압 학습 제어를 실행할 때에는, 무단 변속기 (18) 의 변속에 의한 엔진 회전 속도 (Ne) 의 과도한 변동이 학습 중에 쉽게 발생하는 주행 상태에서는 L/U 클러치 (15) 의 걸어맞춤을 금지함으로써, L/U 클러치압 학습 제어의 학습 정밀도를 향상시킬 수 있다. 이에 더하여, L/U 클러치압 학습 제어를 실행할 때에는, 무단 변속기 (18) 의 변속에 의한 엔진 회전 속도 (Ne) 의 과도한 변동이 학습 중에 쉽게 발생하는 주행 상태에 있어서 단순히 L/U 클러치 (15) 의 걸어맞춤을 금지할 뿐만 아니라, 그 과도한 변동이 학습 중에 잘 발생하지 않는 주행 상태가 된 후에 L/U 클러치 (15) 를 걸어맞춤으로써, L/U 클러치압 학습 제어의 학습 빈도의 저하를 억제할 수 있다.
