Abstract
A method for controlling brake assemblies of a vehicle is provided. Responsive to identifying a locked wheel protection event for a first wheel of a paired set of wheels on the vehicle, where the paired set of wheels is the first wheel on one side of the vehicle and a second wheel on an opposite side of the vehicle, a first brake pressure to a first brake assembly associated with the first wheel is released to zero pounds per square inch (PSI) and a second brake pressure to a second brake assembly associated with the second wheel of the paired set of wheels is reduced by a predetermined amount thereby reducing a yaw effect to the vehicle.

A method for controlling brake assemblies of a vehicle, the method comprising:
- responsive to identifying a locked wheel protection event for a first wheel of a paired set of wheels on the vehicle, wherein the paired set of wheels is the first wheel on one side of the vehicle and a second wheel on an opposite side of the vehicle:
- reducing a first brake pressure to a first brake assembly associated with the first wheel to zero pounds per square inch (PSI);
- and
- reducing a second brake pressure to a second brake assembly associated with the second wheel of the paired set of wheels by a predetermined amount in order to reduce a yaw effect to the vehicle;
- determining whether the first wheel has recovered from the locked wheel protection event;
- and
- responsive to the first wheel recovering from the locked wheel protection event, returning the first brake pressure and the second brake pressure to a braking pressure being commanded by a brake pedal of the vehicle.
A braking system for controlling brake assemblies of a vehicle, the braking system comprising:
- a brake control unit, wherein the brake control unit is configured to:
- responsive to identifying a locked wheel protection event for a first wheel of a paired set of wheels on the vehicle, wherein the paired set of wheels is the first wheel on one side of the vehicle and a second wheel on an opposite side of the vehicle:
- reduce a first brake pressure to a first brake assembly associated with the first wheel to zero pounds per square inch (PSI);
- and
- reduce a second brake pressure to a second brake assembly associated with the second wheel of the paired set of wheels by a predetermined amount in order to reduce a yaw effect to the vehicle;
- determine whether the first wheel has recovered from the locked wheel protection event;
- and
- responsive to the first wheel recovering from the locked wheel protection event, return the first brake pressure and the second brake pressure to a braking pressure being commanded by a brake pedal of the vehicle.
An aircraft, the aircraft comprising:
- a first wheel and a second wheel;
- a first brake assembly associated with the first wheel;
- a second brake assembly associated with the second wheel;
- and
- a brake control unit, wherein the brake control unit is configured to:
- responsive to identifying a locked wheel protection event for the first wheel:
- reduce a first brake pressure to the first brake assembly to zero pounds per square inch (PSI);
- and
- reduce a second brake pressure to the second brake assembly by a predetermined amount in order to reduce a yaw effect to the aircraft;
- determine whether the first wheel has recovered from the locked wheel protection event;
- and
- responsive to the first wheel recovering from the locked wheel protection event, return the first brake pressure and the second brake pressure to a braking pressure being commanded by a brake pedal of the aircraft.
