Abstract: A passenger boarding bridge is capable of avoiding docking by backward travel of travel wheels. The passenger boarding bridge includes: a rotunda connected to a terminal building and supported to be rotatable horizontally; a tunnel unit, whose proximal end is connected to the rotunda, that is extendable and retractable; a cab provided at a distal end of the tunnel unit and configured to be docked with an aircraft; travel wheels supporting the tunnel unit and configured to travel forward and backward in changeable directions; an operating device that is operated to input an operation command to the travel wheels; and a determiner configured to repeatedly perform determination whether or not the current direction of the forward travel of the travel wheels is within a predetermined range during a period from when the cab starts being moved from a predetermined position until the cab is docked with the aircraft.

Abstract: A passenger boarding bridge includes: a rotunda rotatable about a vertical axis; a tunnel unit; a cab; a lifting/lowering mechanism; and a travel unit. A control method includes, at a time of docking the cab with an entrance of an aircraft: calculating relative positional information indicating a position of the entrance as seen from the cab when the travel unit is at a movement start position; calculating positional information of a destination position based on the movement start position and the relative positional information in a case where a distance from the movement start position to the destination position is less than a horizontal distance from the vertical axis to a center point of the travel unit; calculating a target travel angle; and controlling the travel unit such that a travel angle of the travel unit is kept to the target travel angle during traveling.
