  • Patent number: 9457890
    Abstract: A control device 20 for an aircraft steering apparatus controls an aircraft steering apparatus 1 comprising an operation unit including rudder pedals 4, a main pilot steering handle 2 and a co-pilot steering handle 3 which are provided in a cockpit of an aircraft, and an actuator 6 driven in accordance with an operation amount output from the operation unit for driving and steering at least a steered wheel 5, and the control device 20 includes a switching control unit 22 exclusively switches, based on instruction input from at least one of a main pilot and a co-pilot, which of operation amounts corresponding to operation of the rudder pedals 4, the main pilot steering handle 2 and the co-pilot steering handle 3 is used for driving the actuator 6.
    Type: Grant

  • Patent number: 8630750
    Abstract: A steering control equipment has a controller having a provisional-target-angular-position calculating section calculating a provisional target angular position of a steering mechanism corresponding to the operation amounts of a steering handle and rudder pedals, a speed setting section setting the aircraft speed on the basis of detected ground speed and airspeed, a target-angular-position limiting section outputting the provisional target angular position as a final target angular position when the calculated provisional target angular position is equal to or lower than a limit value corresponding to the set speed and outputting the limit value as a final target angular position when the calculated provisional target angular position is larger than the limit value, and a actuating control section controlling an actuating mechanism for actuating the steering mechanism so that the output final target angular position and the actual angular position of the steering mechanism detected coincide with each other.
