SYSTEM FOR MONITORING FOR RISK OF ROAD SHOULDER COLLAPSE, AND TRANSPORT VEHICLE
First Claim
1. A road shoulder collapse risk monitoring system, comprising:
- shoulder shape measuring means for measuring a shape and slope angle of a road shoulder around a vehicle;
measurement position identification means for identifying a wheel position relative to the shoulder when the shoulder shape measuring means measures the shape and slope angle of the shoulder;
shoulder strength calculating means for calculating, from the shape and slope angle of the shoulder measured by the shoulder shape measuring means, strength of the shoulder at the wheel position identified by the measurement position identification means;
wheel load measuring means for measuring a wheel load of the wheel whose position is identified by the measurement position identification means; and
collapse risk information presenting means for presenting information on a risk of a collapse of the shoulder at the wheel position identified by the measurement position identification means by comparing the shoulder strength calculated by the shoulder strength calculating means, with the wheel load measured by the wheel load measuring means.

Abstract
Disclosed herein is a shoulder collapse risk monitoring system capable of alerting a driver to a risk of a road shoulder collapse during approach operations to the shoulder.
The system includes: a shoulder shape measuring device 101 that measures a shape and slope angle of a road shoulder around a vehicle; a measurement position identification section 121 that identifies a wheel position relative to the shoulder when the shape and slope angle of the shoulder are measured by the shoulder shape measuring device; a shoulder strength calculating section 122 that calculates, from the shape and slope angle of the shoulder measured by the shoulder shape measuring device, strength of the shoulder at the wheel position identified by the measurement position identification section; a wheel load measuring section 123 that measures a wheel load of the wheel whose position has been identified by the measurement position identification section; and an alert device 105 that presents information on a risk of a collapse of the shoulder at the identified wheel position by comparing the wheel load measured by the wheel load measuring section, with the shoulder strength calculated by the shoulder strength calculating section.

11. A road shoulder collapse risk monitoring system, comprising:
-
shoulder shape measuring means for measuring a shape and slope angle of a road shoulder around a vehicle; measurement position identification means for identifying a position of the vehicle relative to the shoulder when the shoulder shape measuring means measures the shape and slope angle of the shoulder; shoulder strength calculating means for calculating, from the shape and slope angle of the shoulder measured by the shoulder shape measuring means, strength of the shoulder at the vehicle position identified by the measurement position identification means; wheel load measuring means for measuring a total of wheel loads of the vehicle; and collapse risk information presenting means for comparing the total wheel load measured by the wheel load measuring means, with the shoulder strength calculated by the shoulder strength calculating means, and then after calculating an allowance of the shoulder strength for the total wheel load, further presenting information on a risk of a collapse of the shoulder at the vehicle position identified by the measurement position identification means, on the basis of a magnitude of the allowance.
