Abstract
Systems and methods disclosed herein may be useful emergency braking systems for use in, for example, an aircraft. A system is disclosed that allows emergency braking without the need for a manually operated emergency brake. For example, a system is provided comprising a potentiometer in mechanical communication with a brake pedal, a first electronic switch in electrical communication with the potentiometer, a second electronic switch indicating a displacement of the brake pedal, wherein a brake control valve opens in response to the first electronic switch, and wherein a shutoff valve opens in response to the second electronic switch.
Claims20
A system comprising
- a potentiometer in mechanical communication with a brake pedal;
- a first electronic switch in electrical communication with the potentiometer;
- a second electronic switch configured to toggle in response to a displacement of the brake pedal;
- a first OR gate in electrical communication with the second electronic switch;
- and
- the first OR gate in electrical communication with a standard input,
- wherein the first OR gate is in electrical communication with a shutoff valve
- wherein a brake control valve opens in response to the first electronic switch,
- wherein the shutoff valve opens in response to the first OR gate and the standard input,
- wherein the shutoff valve controls the output of a hydraulic fluid to the brake control valve.
A method comprising:
- receiving, at a potentiometer, a voltage in accordance with displacement of a brake pedal;
- opening a first electronic switch in response to an OR gate;
- toggling a second electronic switch in response to displacement of the brake pedal;
- receiving, at a brake control valve, a control signal through the first electronic switch;
- and
- receiving, at a shutoff valve, a control signal through a second OR gate, the second OR gate being in electrical communication with the second electronic switch, wherein the shutoff valve controls the output of a hydraulic fluid to the brake control valve.
A system comprising
- a potentiometer in electrical communication with a brake pedal;
- a first electronic switch in electrical communication with the potentiometer;
- a second electronic switch configured to toggle in response to a displacement of the brake pedal;
- a first OR gate in electrical communication with the second electronic switch;
- and
- the first OR gate in electrical communication with a standard input,
- wherein an electronic brake control actuator receives a braking command in response to the first electronic switch, and
- wherein the electronic brake control actuator commands braking in response to the OR gate.
