In an automatic follow-up control executed by a traveling control unit, an intervehicle time is calculated by dividing an intervehicle distance by an own vehicle speed. When a preceding vehicle exists in the state that the automatic follow-up control is canceled and a state that the intervehicle time is set to a value within a set range continues for a set period of time, it is determined that the own vehicle is in a follow-up driving state executed by the driver. In this state, the driving information of the own vehicle operated by the driver is repeatedly obtained, and the target control values of the automatic follow-up control are learned based on the driving information. With the above operation, it is possible to learn necessary data accurately by a minimum amount of calculation and to execute the automatic follow-up control with a good drive feeling.
