Abstract
An attention calling system includes a time headway (THW) acquisition unit that repeatedly acquires THW at predetermined time intervals, the THW being a value obtained by dividing an inter-vehicle distance between own vehicle and a preceding vehicle by vehicle speed of the own vehicle, an identification unit that identifies a type of the preceding vehicle, and a notification unit that outputs to an occupant of the own vehicle an approach alarm that notifies an approach to the preceding vehicle when the THW becomes a first threshold or less. The notification unit outputs the approach alarm by using the first threshold that takes different values depending on the type of the preceding vehicle, and/or by setting a saliency level that is a degree of saliency of the approach alarm to a first level that has different magnitudes depending on the type of the preceding vehicle.
