Abstract
A method for controlling brakes may comprise detecting, by a brake control unit (BCU), an aircraft speed, determining, by the BCU, that the aircraft speed is at least one of at or above a threshold value, determining, by the BCU, that an auto-brake control has been enabled, receiving, by the BCU, an antiskid desired pressure that is output from an antiskid control, the BCU comprising a brake control executive (BKX), the antiskid desired pressure being received by the BCU, and receiving, by the BCU, a desired pressure comprising at least one of a deceleration control desired pressure from a deceleration control (DK) or a pilot desired pressure from a manual brake control, the desired pressure being received by the BKX.

A method for controlling brakes using a brake control system comprising, a set of pilot controls including an auto-brake control and a manual brake control, a brake control unit (BCU) comprising a brake control executive (BKX) and a switch logic, the BKX in electronic communication with the switch logic, a deceleration control (DK) in electronic communication with the BCU, and an antiskid control (ASK) in electronic communication with the BCU, the method comprising:
- receiving, by the DK, a deceleration command from an auto-brake control;
- receiving, by the DK, a wheel speed value associated with one or more wheels;
- receiving, by the DK, a wheel acceleration value associated with the one or more wheels;
- generating, by the DK, a DK desired pressure value for each of the one or more wheels, the DK desired pressure value based upon the deceleration command, wheel speed value, and the wheel acceleration value;
- receiving, by the BKX, an ASK desired pressure value from the ASK;
- sending, via the switch logic, at least one of the DK desired pressure value from the DK to the BKX or a pilot desired pressure value from the manual brake control to the BKX;
- and
- controlling, by the brake control system, a braking force for the one or more wheels based upon the DK desired pressure value.
A brake control system, comprising:
- a set of pilot controls including an auto-brake control and a manual brake control;
- a brake control unit (BCU) comprising a brake control executive (BKX) and a switch logic, the BKX in electronic communication with the switch logic;
- a deceleration control (DK) in electronic communication with the BCU,
- wherein the DK is configured to receive a deceleration command from the auto-brake control, a wheel speed value associated with one or more wheels, and a wheel acceleration value associated with the one or more wheels, the DK is configured to send a DK desired pressure value for each of the one or more wheels to the BKX, the DK desired pressure value based upon the wheel speed value and the wheel acceleration value;
- and
- an antiskid control (ASK) in electronic communication with the BCU,
- wherein the BKX is configured to receive an ASK desired pressure value from the ASK,
- wherein the switch logic is configured to send at least one of the DK desired pressure value from the DK to the BKX or a pilot desired pressure value from the manual brake control to the BKX.
A brake control system, comprising:
- a set of pilot controls including an auto-brake control and a manual brake control;
- a brake control unit (BCU) comprising a brake control executive (BKX) and a switch logic, the BKX in electronic communication with the switch logic;
- a deceleration control (DK) in electronic communication with the BCU;
- an antiskid control (ASK) in electronic communication with the BCU;
- a processor;
- and
- a tangible, non-transitory memory configured to communicate with the processor, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the processor, cause the brake control system to perform operations comprising:
- receiving, by the DK, a deceleration command from an auto-brake control;
- receiving, by the DK, a wheel speed value associated with one or more wheels;
- receiving, by the DK, a wheel acceleration value associated with the one or more wheels;
- generating, by the DK, a DK desired pressure value for each of the one or more wheels, the DK desired pressure value based upon the deceleration command, wheel speed value, and the wheel acceleration value;
- receiving, by the BKX, an ASK desired pressure value from the ASK;
- sending, via the switch logic, at least one of the DK desired pressure value from the DK to the BKX or a pilot desired pressure value from the manual brake control to the BKX;
- and
- controlling, by the brake control system, a braking force for the one or more wheels based upon the DK desired pressure value.
