Patent ID: 8185289

Claim:
A vehicle driving support apparatus comprising: a tire type determination device for determining a type of a tire mounted on a vehicle; a memory medium for storing a curvature threshold data, which shows a relationship between the type of the tire and a curvature threshold in such a manner that the curvature threshold becomes smaller as a grip performance of the tire increases; a curve determination device for determining based on a current position of the vehicle and a road data whether a curve is disposed on a road ahead of the vehicle; a curvature threshold determination device for specifying the curvature threshold corresponding to the tire mounted on the vehicle based on the type of the tire determined by the tire type determination device and the curvature threshold data stored in the memory medium when the curve determination device determines that the curve is disposed on the road ahead of the vehicle; and a warning guidance performing device for performing curve warning guidance to a driver when the warning guidance performing device determines that a curvature of the curve ahead of the vehicle is smaller than the curvature threshold specified by the curvature threshold determination device.
