Vehicle wrong-way travel detection device
First Claim
1. A vehicle wrong-way travel detection device, comprising:
- a vehicle position detector that detects a position of a vehicle;
a traveling direction detector that detects a vehicle traveling direction along which the subject vehicle is traveling;
a storage device where map information is stored;
a control unit that executes various types of processings; and
an output unit that outputs various types of information, wherein;
the control unit;
creates a wrong-way travel decision-making area to be used to make a decision as to whether or not the vehicle is traveling against a traffic flow;
makes a decision as to whether or not the vehicle is traveling against the traffic flow when the position of the vehicle detected by the vehicle position detector is within the wrong-way travel decision-making area; and
deletes the created wrong-way travel decision-making area when a predetermined condition is satisfied, andthe output unit outputs information to warn a user that the vehicle is traveling against the traffic flow when the control unit has decided that the vehicle is traveling against the traffic flow.

Abstract
A vehicle wrong-way travel detection device includes a map information storage unit where map information is stored, a decision-making point setting unit that sets, based upon the map information stored in the map information storage unit, the connecting point located ahead along a subject vehicle traveling direction as a decision-making point, a wrong-way travel decision-making area setting unit that sets wrong-way travel decision-making areas for at least one of a plurality of roads connected to the decision-making point, and a wrong-way travel decision-making unit that makes a decision, based upon the direction of traffic flow set for a unidirectional traffic road connected to the decision-making point and the subject vehicle traveling direction, as to whether or not the subject vehicle is traveling against the flow of traffic on the unidirectional traffic road.
