Abstract

Methods and systems are provided for improved autobraking systems for aircraft. Such systems and methods include a pedal balance controller configured to receive one of a yaw angle, a yaw speed, and a wheel speed, and an autobrake pedal executive module configured to send an autobrake left pedal command and an autobrake right pedal command to a pedal executive module, wherein the pedal executive module is configured to execute a pedal command. These systems and methods may assist a pilot in maintaining a desired course during autobraking.

First claim

What is claimed is:

1. An aircraft autobraking system comprising:
an autobrake controller configured to send an initial single autobrake pedal command based on an aircraft acceleration target, wherein the initial single autobrake pedal command is generated by the autobrake controller independent from a pilot pedal input;
a pedal balance controller configured to send an autobrake pedal correction factor;
an autobrake pedal executive controller configured to receive at least one of the autobrake pedal correction factor from the pedal balance controller or the initial single autobrake pedal command from the autobrake controller;
the autobrake pedal executive controller configured to send an autobrake left pedal command and an autobrake right pedal command to a pedal executive controller, wherein the autobrake left pedal command and the autobrake right pedal command are independent from the pilot pedal input; and
a pedal braking controller configured to execute a pedal command received from the pedal executive controller.

2. The system of claim 1 , wherein the autobrake controller is configured to receive an aircraft acceleration feedback, wherein the initial single autobrake pedal command is based on the aircraft acceleration feedback.

3. The system of claim 2 , wherein the aircraft acceleration target is set by a cockpit device.

4. The system of claim 1 , wherein the autobrake controller is configured to send the initial single autobrake pedal command to the autobrake pedal executive controller.

5. The system of claim 1 , wherein the at least one autobrake pedal correction factor is a plurality of autobrake pedal correction factors.

6. The system of claim 5 , wherein the pedal balance controller is configured to receive at least one of a yaw angle, a yaw speed, or a wheel speed.

7. The system of claim 1 , wherein the pedal executive controller is configured to receive the pilot pedal input, the pilot pedal input comprising a pilot left pedal input and a pilot right pedal input.

8. The system of claim 1 , wherein the autobrake left pedal command and the autobrake right pedal command are calculated to maintain a desired course of the aircraft.

9. A method for autobraking an aircraft comprising:
receiving, at an autobrake controller, an aircraft acceleration target;
receiving, at a pedal balance controller, at least one of a yaw angle, a yaw speed, or a wheel speed;
generating, by the autobrake controller, an initial single autobrake pedal command, the initial single autobrake pedal command being generated independent from a pilot pedal input and the initial single autobrake pedal command being based on the aircraft acceleration target;
receiving, at an autobrake pedal executive controller, the initial single autobrake pedal command from the autobrake controller;
sending, from the pedal balance controller, an autobrake pedal correction factor to the autobrake pedal executive controller, the autobrake pedal correction factor being independent from the pilot pedal input;
sending, from the autobrake pedal executive controller, an autobrake left pedal command and an autobrake right pedal command to a pedal executive controller, the autobrake left pedal command and the autobrake right pedal command independent from the pilot pedal input;
sending, from the pedal executive controller, a pedal command based on the autobrake left pedal command and the autobrake right pedal command; and
executing, by a pedal braking controller, the pedal command received from the pedal executive controller.

10. The method of claim 9 , further comprising receiving, at the autobrake controller, an aircraft acceleration feedback.

11. The method of claim 9 , wherein the aircraft acceleration target is received from a cockpit device.

12. The method of claim 9 , further comprising receiving, at the autobrake pedal executive controller, the at least one autobrake pedal correction factor.

13. The method of claim 12 , wherein executing the pedal command comprises sending a signal to an electric brake system.

14. The method of claim 12 , wherein executing the pedal command comprises sending a signal to a hydraulic brake system.

15. The method of claim 9 , wherein the autobrake left pedal command and the autobrake right pedal command are calculated to maintain a desired course of the aircraft.

16. The method of claim 9 , further comprising receiving, at the pedal executive controller, the autobrake left pedal command and the autobrake right pedal command prior to sending the pedal command.

17. The method of claim 16 , further comprising receiving, at the pedal executive controller, the pilot pedal input prior to sending the pedal command.

18. The method of claim 17 , wherein the pilot pedal input comprises a pilot left pedal input and a pilot right pedal input.

19. The method of claim 9 , wherein the pedal command is based on the at least one of the yaw angle, the yaw speed, or the wheel speed.

20. The method of claim 9 , wherein the autobrake pedal executive controller is configured to provide automatic deceleration of the aircraft independent of the pilot pedal input.
