A method includes receiving an input brake command that indicates a
desired amount of braking for a vehicle. A brake control signal is then
derived from the input brake command to facilitate applying a braking
force to a wheel of the vehicle, and the braking force facilitates
achieving the desired amount of braking for the vehicle. The method
further comprises determining that data from a sensor associated with the
wheel is unavailable, and then modifying the brake control signal in
response to determining that the data is unavailable. The modification
may be based on sensor data or controller output associated with a second
wheel where data is available. Such modification facilitates the desired
amount of braking for the vehicle.
