Abstract
An attention calling system includes a time headway (THW) acquisition unit repeatedly acquiring THW at predetermined time intervals, the THW being a value obtained by dividing an inter-vehicle distance between an own vehicle and a preceding vehicle by vehicle speed of the own vehicle, a time to collision (TTC) acquisition unit repeatedly acquiring TTC at predetermined time intervals, the TTC being a value obtained by dividing the inter-vehicle distance by relative speed between the own vehicle and the preceding vehicle, and a notification unit outputting to an occupant of the own vehicle an approach alarm that notifies an approach to the preceding vehicle, based on the THW and the TTC. The notification unit determines a saliency level that is a degree of saliency of the approach alarm in accordance with the THW and the TTC, and outputs the approach alarm of the determined saliency level.
