Cargo handling control device

A cargo handling control device that moves a forklift truck from a start position to a cargo handling target and performs cargo handling, the cargo handling control device comprising:

• a target detector configured to detect the cargo handling target;
• a position calculator configured to calculate a position of the cargo handling target relative to the forklift truck based on detection data by the target detector;
• an approach controller configured to control the forklift truck based on the position of the cargo handling target relative to the forklift truck calculated by the position calculator while the forklift truck is at the start position so that the forklift truck approaches a cargo handling position corresponding to the cargo handling target;
• an approach determiner configured to determine whether an approach of the forklift truck to the cargo handling position is successful based on the position of the cargo handling target relative to the forklift truck calculated by the position calculator when the forklift truck reaches the cargo handling position;
• a cargo handling controller configured to control the forklift truck so that the forklift truck performs cargo handling of the cargo handling target when the approach determiner determines that the approach of the forklift truck to the cargo handling position is successful;
• and
• a re-approach controller configured to control the forklift truck so that the forklift truck re-approaches the cargo handling position based on the position of the cargo handling target relative to the forklift truck calculated by the position calculator when the approach determiner determines that the approach of the forklift truck to the cargo handling position is unsuccessful.
