Intersection warning system
First Claim
1. An intersection warning system provided in a vehicle comprising:
- a receiving unit that receives watching information about states of bodies in a watching area including an intersection, the watching information being transmitted from a road watching apparatus which watches the watching area;
a vehicle position detecting unit that detects a position of said vehicle;
a dead angle area calculation unit that calculates a dead area for said vehicle based on the position detected by said vehicle position detecting unit and the watching information received by said receiving unit;
a first determination unit that determines whether there is another vehicle in the dead angle area calculated by said dead angle area calculation unit;
a running state detecting unit that detects a running state of said vehicle;
a second determination unit that, when said first determination unit determines that there is another vehicle in the dead angle, determines, based on the running state of said vehicle detected by said running state detecting unit and the watching information about said another vehicle in the dead angle area, whether a driving operation for said vehicle is appropriate; and
a warning unit that issues a warning based on a determination result obtained said second determination unit.

Abstract
An intersection warning system provided in a vehicle includes a receiving unit that receives watching information, about states of bodies in a watching area including an intersection, from a road watching apparatus, a vehicle position detecting unit that detects a position of the vehicle, a dead angle area calculation unit that calculates a dead area for the vehicle based on the position detected by the vehicle position detecting unit and the watching information received by the receiving unit, a first determination unit that determines whether there is another vehicle in the dead angle area calculated by the dead angle area calculation unit, a running state detecting unit that detects a running state of the vehicle, a second determination unit that, when the first determination unit determines that there is another vehicle in the dead angle, determines, based on the running state of the vehicle detected by the running state detecting unit and the watching information about the another vehicle in the dead angle area, whether a driving operation for the vehicle is appropriate, and a warning unit that issues a warning based on a determination result obtained the second determination unit.
