Abstract: An object of the present invention is to safely and efficiently execute operation such as cargo handling in a cargo vehicle such as an automatic forklift 1. In order to achieve the above object, in the present invention, a laser scanner 2 that monitors a vehicle safety monitoring range 4 and laser curtains 21 that monitor a safety monitoring area 211 are prepared, and these are caused to function in cooperation with each other according to a status of operation of the automatic forklift 1. As one aspect of this, in the present invention, in a case where the safe state in the safety monitoring area 211 is confirmed using the laser curtains 21 at the time of executing cargo handling, a vehicle safety monitoring invalidation range 41 is set by invalidating the vehicle safety monitoring range 4 by the laser scanner 2.
