1. A vehicle control device applied to a vehicle including an internal combustion engine provided with an exhaust gas reduction catalyst in an exhaust passage, and a transmission provided with a parking lock mechanism, wherein the vehicle control device performs a catalyst warm-up operation for promoting warm-up of the catalyst when the internal combustion engine is started and there is a warm-up request for the catalyst, and a catalyst warm-up operation switching process in which in a case where the catalyst warm-up operation is performed when the parking lock mechanism is operated, a first catalyst warm-up operation is performed, while in a case where the catalyst warm-up operation is performed when the parking lock mechanism is not operated, a second catalyst warm-up operation is performed, wherein the rotational fluctuation of the internal combustion engine is larger when the second catalyst warm-up operation is performed than when the first catalyst warm-up operation is performed.
