  • Patent number: 10302436
    Abstract: A path searching apparatus includes: a path searching unit that searches for an optimal path of a movable body that performs traveling from a start node to a goal node by performing a path searching process based on A-Star algorithm, and a predicting unit that predicts a surrounding situation of the movable body at each of times in future. The path searching unit determines whether a first surrounding situation involves a change from a second surrounding situation, on a basis of the predicted surrounding situation, and upon determining that the first surrounding situation involves the change, updates an estimated smallest cost value h* of a node on which the searching has been already performed, on a basis of the first surrounding situation.

The method also includes, prior to the step of computing a reception flight plan: a step of determining the time, called the recognition time, assumed to have to elapse between the current time and a time at which the said control clearance is assumed to be recognized; a step of attribution, to the said control clearance, of a destination flight plan as a function of the recognition time, the said destination flight plan being the temporary flight plan when the recognition time is included in a first time slot and the destination flight plan being a secondary flight plan when the recognition time is included in a second time slot longer than the first time slot.

  • Patent number: 8583352
    Abstract: A method and hold path computation system for automatically generating a hold path for an aircraft flying in a holding pattern, wherein the holding pattern is defined by one or more orbits within a selectable holding area are provided. The system includes a processor configured to receive a hold departure time indicating a time the aircraft is to leave the hold path to meet a required time of arrival (RTA) at a waypoint, determine a present position of the aircraft within the holding pattern, and determine an amount of time to complete a current hold orbit. The processor is also configured such that if the determined amount of time to complete a current hold orbit is less than or equal to the hold departure time, maintain the aircraft flying in the holding pattern and determine an amount of time by which to shorten the next orbit to exit the holding pattern at the hold departure time.

  • Patent number: 8521416
    Abstract: A vehicle control apparatus includes a first section that recognizes a lane boundary line of a lane in which a vehicle is traveling. A second section recognizes a present position of a predetermined reference point of the vehicle. A third section calculates a predicted position of the reference point, wherein the predicted position is a predetermined interval ahead of the present position. A fourth calculates an imaginary lane boundary line, wherein the imaginary lane boundary line is tangent to the lane boundary line at a point close to the predicted position. A fifth section performs a control of preventing the vehicle from deviating from the lane by controlling the vehicle depending on positional relationship between the vehicle and the lane boundary line. A sixth section selectively permits and suppresses the control depending on positional relationship among the imaginary lane boundary line, the present position, and the predicted position.

  • Patent number: 8467916
    Abstract: A method of a flight management system (FMS) of an aircraft for generating an equi-time point (ETP) for an emergency landing of the aircraft includes receiving at least two reference points for landing the aircraft upon an occurrence of an emergency. The method also includes determining an equi-distance point (EDP) for the aircraft by locating a first point on the remaining flight path of the aircraft which is equidistant from the at least two reference points. The method further includes generating an ETP for the aircraft by locating a second point on the remaining flight path such that time difference between any two of expected flight times of the aircraft from the second point to the at least two reference points is less than a threshold value.

  • Publication number: 20130085661
    Abstract: According to aspects of the embodiments, there is provided an apparatus and method to synchronize trajectories from independent systems such as from a flight management system and the ground Air traffic control during the entire history of a flight. Since a number of trajectory discrepancy factors will intervene during the lifetime of a flight, such as a change in flight intent, controller intervention, or large deviations of the actual flight from the predicted trajectory due to prediction errors, there is need to dynamically monitor these deviations and control a dynamic synchronization cycle. A dynamic trajectory synchronization algorithm attempts to bring each of the systems back into balance whenever a disturbance causes an imbalance.

  • Patent number: 8401732
    Abstract: Disclosed are a vehicle control device and a vehicle control method capable of performing appropriate traveling control while exhibiting the capability of a control system. Feedback control is performed according to a traveling target set in advance. At the time of the feedback control, when a vehicle traveling trace is deviated, when a tire friction circle is exceeded, or when a vehicle acceleration or a jerk exceeds a set value, if a control deviation exceeds a set value, a traveling target is regenerated. This enables appropriate traveling control while sufficiently exhibiting the capability of the control system until the control deviation exceeds the set value. When the control deviation exceeds the set value, a traveling target is regenerated, such that traveling control appropriate for the traveling environment can be performed.

  • Patent number: 8386097
    Abstract: Disclosed is a method and device for assisting guidance of an aircraft. A flight management system is used to determine guidance instructions that include speed instructions having at least one flight time constraint to guide the aircraft to a check-point. An accuracy level for complying with the flight time constraint and at least one error level for at least one flight parameter are generated by an accuracy generating unit. An operating margin for at least one second parameter is determined from the determined accuracy and error levels, with the operating margin being representative of air speed criterion values of the aircraft. A range determining unit is used to determine whether the range of air speed criterion values is within an air speed envelope of the aircraft, and the speed instructions are modified when the range of air speed criterion values is not within the air speed envelope.

  • Patent number: 8380424
    Abstract: Systems and methods for providing vehicle-centric collision avoidance are disclosed. In one embodiment, a method includes determining a first flight trajectory for a first aircraft. The method also includes determining a second flight trajectory for a second aircraft. A distance between the first aircraft and the second aircraft at a first closest point of approach (CPA) is predicted. The predicted closest point of approach is then compared to a separation perimeter layer. The separation perimeter layer is configured to provide a minimum separation distance from the first aircraft to the second aircraft. When the predicted closest point of approach breaches the separation perimeter, the first flight trajectory is altered to provide collision avoidance.
