Abstract
A driving support ECU of an alert apparatus obtains, when a preceding vehicle comes closer to a host vehicle rapidly in a following preceding vehicle state in which the host vehicle is following the preceding vehicle owing to a driving operation by a host vehicle driver, operation characteristics values representing characteristics of a deceleration operation performed by the host vehicle driver to decelerate the host vehicle, and memorize operation characteristics learning values that vary depending on the operation characteristics values. The ECU obtains an assumed deceleration of the preceding vehicle in accordance with a type of a road and/or a traffic flow. The ECU calculates a 'required inter-vehicular distance' using the assumed deceleration, and performs the alert operation when an alert condition is determined to be satisfied. The alert condition includes a condition to be satisfied when an inter-vehicular distance is shorter than the required inter-vehicular distance.
