1. A driving support system for use in a vehicle comprising:
- a light control unit for controlling a light of the vehicle, wherein the light is controlled to light an intersection road surface when the vehicle is stopping at a stop position of an intersection;
a signal transmission unit for transmitting an entrance signal before the vehicle is entering the intersection, wherein the entrance signal is transmitted when lighting on the intersection road surface by a stopping vehicle at the intersection is detected by the transmission unit; and
a notification unit for providing a stop notification that encourages a driver to stop at the stop position of the intersection for an extended time, wherein the notification unit provides the stop notification when the entrance signal is received by the notification unit,wherein at least two vehicles equipped with the light control unit, the signal transmission unit and the notification unit are organized as a system for supporting driving operation of the respective vehicles.

Abstract
A driving support system for use in a vehicle uses a headlight controller for directing a headlight beam on a road surface in an intersection when the vehicle stops at the intersection. Another vehicle simultaneously approaching the intersection detects the beam of the surface with an image sensor and processor of the driving support system. The system of the another vehicle sends back a vehicle ID signal to the stopping vehicle when a predetermined beam pattern is recognized by the processor. Then, the system uses a buzzer for notifying a driver of the stopping vehicle that the ID signal has been returned.
