Abstract
A method for braking an aircraft is disclosed herein. The method includes receiving, by a brake controller, a first signal from a position sensor of a first pedal, receiving, by the brake controller, a second signal from a pedal sensor of the first pedal, determining, by the brake controller, that the pedal is being pressed based on the first and second signals, and sending, by the brake controller, an instruction to apply a brake pressure in response to the determination that the pedal is being pressed.
Claims15
A method of braking an aircraft, comprising:
- receiving, by a brake controller, a first signal from a position sensor of a first pedal;
- receiving, by the brake controller, a second signal from a pedal sensor of the first pedal;
- determining, by the brake controller, that the pedal is being pressed based on the first and second signals;
- calculating, by the brake controller, an amount of pressure to apply based on the first signal;
- receiving, by the brake controller, a second amount of pressure to apply from a second brake controller;
- comparing, by the brake controller, the amount of pressure to apply and the second amount of pressure to apply;
- and
- sending, by the brake controller, an instruction to apply a brake pressure in response to the determination that the amount of pressure and the second amount of pressure are the same.
An article of manufacture including a tangible, non-transitory computer-readable storage medium having instructions stored thereon that, in response to execution by a processor, cause the processor to perform operations comprising:
- receiving, by a brake controller, a first signal from a position sensor of a pedal;
- receiving, by the brake controller, a second signal from a pedal sensor of the pedal;
- determining, by the brake controller, whether or not the pedal is being pressed based on the first signal and the second signal;
- calculating, by the brake controller, an amount of pressure to apply based on the first signal;
- receiving, by the brake controller, a second amount of pressure to apply from a second brake controller;
- comparing, by the brake controller, the amount of pressure to apply and the second amount of pressure to apply;
- and
- sending, by the brake controller, an instruction to apply a brake pressure in response to a determination that the amount of pressure and the second amount of pressure are the same.
A brake system for an aircraft, comprising:
- a brake assembly configured to supply a brake pressure in response to a pedal being displaced;
- a position sensor configured to provide an indication of an amount of displacement of the pedal;
- a pedal sensor configured to provide an indication that the pedal is being displaced;
- and
- a brake controller configured to control the brake pressure, the brake controller configured to:
- receive a first signal from the position sensor;
- receive a second signal from the pedal sensor;
- determine that the pedal is being activated;
- calculate an amount of pressure to apply based on the first signal;
- receive a second amount of pressure to apply from a second brake controller;
- compare the amount of pressure to apply and the second amount of pressure to identify a fault in the brake system based on the comparison;
- and
- modify the brake pressure as a function of pedal displacement in response to the identification of a fault.
