Abstract

A drive control system (S) includes a measurement portion (1) configured to detect an obstacle (R) in a transportation vehicle (T), and a load collapse determination portion (4) configured to acquire an arrangement of a transportation target (C) loaded on the transportation vehicle (T) based on measurement data of the measurement portion (1) to determine a load collapse of the transportation target (C) based on a change in the arrangement over time.

First claim

The invention claimed is:

1. A drive control system comprising:
a measurement portion configured to detect a surrounding body including a transportation target in a transportation vehicle; and
a load collapse determination portion configured to acquire an arrangement of the transportation target loaded on the transportation vehicle based on measurement data of the measurement portion to determine a load collapse of the transportation target based on a change in the arrangement over time;

wherein
the transportation vehicle includes:
a trailer head provided with the measurement portion; and
a loading platform on which the transportation target is loaded and which is connected to the trailer head; and

the load collapse determination portion detects the change in the arrangement of the transportation target by correcting the measurement data acquired by the measurement portion by a connection angle between the trailer head and the transportation target in a case where the transportation vehicle turns.

2. The drive control system according to claim 1 , wherein the measurement portion performs scanning with laser light to measure a distance between the trailer head and the surrounding body.

3. The drive control system according to claim 2 , wherein the load collapse determination portion uses a set of a plurality of continuous linear measurement points in an outer shape of the transportation target as a reference for the arrangement of the transportation target.

4. The drive control system according to claim 1 , wherein the measurement portion is provided at an upper part of the trailer head.

5. The drive control system according to claim 1 , wherein the measurement portion is provided at each of left and right ends of the trailer head.

6. The drive control system according to claim 2 , wherein the measurement portion is provided at an upper part of the trailer head.

7. The drive control system according to claim 3 , wherein the measurement portion is provided at an upper part of the trailer head.

8. The drive control system according to claim 2 , wherein the measurement portion is provided at each of left and right ends of the trailer head.

9. The drive control system according to claim 3 , wherein the measurement portion is provided at each of left and right ends of the trailer head.
