Vehicle control system
First Claim
1. A vehicle control system for controlling a plurality of vehicles traveling along a plurality of track roads, the system comprising:
- a plurality of position detecting sensors installed on each of the plurality of vehicles and configured to detect a position thereof;
a plurality of parameter detecting sensors installed on each of the plurality of vehicles and configured to detect a parameter indicative of a possibility for a vehicle installed with the position detecting sensor, traveling on one of two adjacent track roads in a two-way traffic area formed by the two adjacent track roads different in vehicle traveling direction, to enter the other of the two adjacent track roads;
a specific spot setting unit configured to execute, on a basis of positions of the plurality of vehicles output from the plurality of position detecting sensors, parameters output from the plurality of parameter detecting sensors, and thresholds related with the parameter, a process setting positions at which the vehicle is likely to enter the other adjacent track road in the two-way traffic area as specific spots;
a storage device configured to store positional information on places set as the specific spots by the specific spot detecting unit; and
a specific area setting unit configured to, while a vehicle of the plurality of vehicles is traveling, set a specific area where traveling of another vehicle of the plurality of vehicles is not permitted, the specific area being a closed area of the two adjacent track roads in the two-way traffic area,wherein the plurality of track roads are each divided into a plurality of segments,wherein the storage device stores the positional information on the specific spots and the information on a time at which the parameters were detected; and
the specific area setting unit sets a first segment and a second segment as the specific area,wherein a segment of the plurality of segments of one of two adjacent track roads in the two-way traffic area is set as the first segment when a number of times the specific spots are set within the segment within a predetermined period of time exceeds a threshold,wherein the second segment is a segment of the plurality of segments of the other of the two adjacent track roads in the two-way traffic area that is adjacent the first segment.

Abstract
A vehicle control system is provided in which, if a position requiring caution for the contact with an oncoming vehicle on a track road is found also on an ex-post facto basis, the information thereof is easily fed back to the control of each vehicle. This vehicle control system has a GPS receiver 101 for detecting the position of each vehicle, an encoder 72 and an IMU 73 mounted on each vehicle, a specific spot setting unit 87 for setting a position requiring caution for the passing with an oncoming vehicle as a specific spot on the basis of a vehicle position, a slip ratio and a curvature that are computed from the values output therefrom, and a storage device for storing the positional information on a place set as a specific spot by a specific spot detecting unit.
