Problems solved by technology

However, in this case, not only the traveling vehicle, but also the transportation of goods by other traveling vehicles will be stopped.
Therefore, there is a possibility that the efficiency of the transportation work performed by these traveling vehicles will be significantly reduced.

Embodiment Construction

[0043] A traveling vehicle according to an embodiment of the present invention will be described with reference to the drawings.

[0044] figure 1 It is a figure which shows the appearance example of the traveling vehicle which concerns on embodiment of this invention.

[0045] figure 1 The traveling vehicle 100 shown is a type of unmanned transport vehicle, and can transport goods 150 from a certain point to another point.

[0046] In addition, traveling vehicle 100 has obstacle sensor 110 at the front end, and can detect the presence of an obstacle in a predetermined area, the distance to the obstacle, and the size and shape of the obstacle.

[0047] In addition, the traveling vehicle 100 can autonomously travel by, for example, laser induction. Specifically, the traveling vehicle 100 travels while projecting laser light around, and detects the positions of a plurality of reflectors arranged around the traveling path by reflected light. The traveling vehicle 100 can auto...

Abstract

A traveling vehicle includes an obstacle sensor; a controller which causes the traveling vehicle to perform a first avoidance operation so as to avoid an obstacle according to a result of the detection of the obstacle; a memory unit configured to store position information indicating a position of the obstacle in a traveling path and avoidance amount information indicating an amount of avoidance in a lateral direction performed by the traveling vehicle in the first avoidance operation; wherein, (a) when the obstacle sensor detects an obstacle at the position indicated by the position information at a point when the obstacle is within a first distance from the traveling vehicle, the controller causes the traveling vehicle to start a second avoidance operation, before the distance from the traveling vehicle to the obstacle reaches a second distance, so as to avoid the obstacle based on the avoidance amount information stored in the memory unit.

Description

technical field [0001] The present invention relates to a traveling vehicle for carrying cargo, and more particularly to a traveling vehicle having an obstacle sensor for detecting obstacles. Background technique [0002] Conventionally, an obstacle sensor that detects an obstacle is mounted on a traveling vehicle such as an unmanned transport vehicle in order to avoid a collision with an obstacle. [0003] The obstacle sensor, for example, projects laser light while rotating, and receives reflected light reflected by objects such as cargo placed in the path of the traveling vehicle. Thereby, for example, the presence of an obstacle, the distance to the obstacle, and the size and shape of the obstacle can be detected within a predetermined area in the traveling direction. [0004] Also disclosed is a technology related to the control of a traveling vehicle that uses the detection result of such a sensor based on the detection object. [0005] For example, according to Japa...
