Abstract
A forklift truck includes a main controller, a driving motor, a drive controller, and an object detector. The drive controller controls the driving motor. The object detector detects the position of an object being present in the backward direction of the forklift truck. The main controller derives an expected trajectory of the forklift truck. The main controller imposes a speed limit on the forklift truck by setting a vehicle speed upper limit when the object detected by the object detector is located within the expected trajectory and the forklift truck is traveling in the direction of approaching the object. The main controller gives commands to the drive controller to prevent the vehicle speed of the forklift truck from exceeding the vehicle speed upper limit.
