Abstract
An intersection warning system provided in a vehicle includes a distance detecting unit detecting a distance between a position at which the vehicle runs toward an intersection and a boundary position (a stop line) set for vehicles to stop before the intersection, a running state detecting unit detecting a running state of the vehicle, a determination unit determining whether the detected running state of the vehicle is appropriate by estimating a running state of the vehicle at the boundary position based on the distance detected by the distance detecting unit and the detected running state of the vehicle, and a warning unit issuing a warning to a driver of the vehicle based on a result obtained by the determination unit.
