Abstract
An alarm device generates an alarm when a distance between a vehicle and an object that exists in a set region in front of the vehicle is smaller than a set distance. A controller of the alarm device determines a tentative set distance based on at least one of a running speed of the vehicle and a relative velocity between the vehicle and the object, and then corrects the tentative set distance based on at least a deceleration of the vehicle, so as to determine a final set distance.
