acquire information about surrounding vehicles around a host vehicle;
control a velocity of the host vehicle based on the presence or absence of preceding vehicles using a driving assistance function and an actuator having a drive device for acceleration of the host vehicle;
select a preceding vehicle suitable as a follow-up target of the host vehicle based on the information about the surrounding vehicles; and
propose to an occupant of the host vehicle a follow-up travel to the preceding vehicle by the host vehicle,
wherein the processor is configured to stop proposal of the follow-up travel when the follow-up travel is not started despite the proposal of the follow-up travel, and
wherein when a situation in which the follow-up travel is not started despite the proposal of the follow-up travel is continued for a predetermined number of trips, the processor is configured not to propose the follow-up travel in next and subsequent trips.
