Claim 9:
10. A method of operating a system for controlling braking of a wheel, the method comprising:
providing, to a main controller, a first signal indicating a speed of a wheel detected by a first wheel speed sensor, the main controller configured to determine a first wheel speed based on the first signal and control braking of the wheel based on the determined first wheel speed;
providing, to an auxiliary controller, a second signal indicating the speed of the wheel detected by a second wheel speed sensor, the auxiliary controller configured to determine a second wheel speed based on the second signal;
determining whether a difference between the first and second wheel speeds is within a predetermined tolerance range;
in response to determining that the difference between the first and second wheel speeds is not within the predetermined tolerance range, determining whether the first or second wheel speed sensor is malfunctioning; and
in response to determining that the first wheel speed sensor is malfunctioning, providing the second signal to the main controller such that the main controller determines the first wheel speed based on the second signal.
