Abstract

Disclosed is a peripheral object detection system to be mounted on a vehicle. The peripheral object detection system includes a peripheral information acquisition device and a detecting range switching mechanism. The peripheral information acquisition device is configured to have, as a detected range, apart of a peripheral space of the vehicle and to acquire distance information to an object that exists in the detected range and is to be detected. The detecting range switching mechanism is configured to switch, toward an area forward or backward of the vehicle, a direction of a detecting range of the peripheral information acquisition device based on forward/backward information that indicates whether the vehicle is moving in a forward direction or in a reverse direction.

First claim

The invention claimed is:

1. A peripheral object detection system to be mounted on a vehicle, comprising:
a first peripheral information acquisition device configured to be mounted on the vehicle and to acquire first distance information to an object to be detected and that exists around the vehicle;
a second peripheral information acquisition device configured to be mounted on the vehicle along a lateral direction of a vehicle body of the vehicle and at an interval from the first peripheral information acquisition device and to acquire second distance information to the object to be defected;
a detecting range switching mechanism configured to switch, toward an area forward or backward of the vehicle, a direction of a field of view of the first peripheral information acquisition device and a direction of a field of view of the second peripheral information acquisition device based on forward or back information that indicates whether the vehicle is moving in a forward direction or in a backward direction, and
a peripheral object computing unit configured to detect a direction of the vehicle body with respect to the object to be detected based on the first distance information and the second distance information.

2. The peripheral object detection system according to claim 1 , wherein the first and second peripheral information acquisition devices are arranged on opposite end portions, in the lateral direction of the vehicle body, on a front section of the vehicle, respectively, and extend outward beyond opposite outermost end faces of the vehicle, the opposite outermost end faces being located outermost in the lateral direction of the vehicle body, respectively.

3. A haulage vehicle comprising:
a haulage vehicle main body,
a first peripheral information acquisition device configured configured to be mounted on the haulage vehicle and to acquire first distance information to an object to be detected and that exists around the haulage vehicle;
a second peripheral information acquisition device configured to be mounted on the haulage vehicle along a lateral direction of the haulage vehicle main body at an interval from the first peripheral information acquisition device and to acquire second distance information to the object to be detected;
a detecting range switching mechanism configured to switch, toward an area forward or backward of the haulage vehicle, a direction of a field of view of the first peripheral information acquisition device and a direction of a field of view of the second peripheral information acquisition device based on forward or back information that indicates whether the haulage vehicle is moving in a forward direction or in a backward direction, and
a peripheral object computing unit configured to detect a direction of the haulage vehicle main body with respect to the object to be detected based on the first distance information and the second distance information.
