Claim 0:
1. A vehicle brake system comprising:
a first wheel speed sensor configured to detect a speed of a wheel and generate a first signal indicating the speed of the wheel detected by the first wheel speed sensor;
a second wheel speed sensor configured to detect the speed of the wheel and generate a second signal indicating the speed of the wheel detected by the second wheel speed sensor;
a main controller configured to generate, based on the first signal generated by the first wheel speed sensor, a first wheel speed signal, and control braking of the wheel based on the first wheel speed signal; and
an auxiliary controller configured to generate, based on the second signal generated by the second wheel speed sensor, a second wheel speed signal,
wherein the main controller is further configured to:
determine whether a difference between the first and second wheel speed signals is within a predetermined tolerance range;
in response to determining that the difference between the first and second wheel speed signals is within a predetermined tolerance range, transmitting, to the auxiliary controller, a normal signal; and
in response to determining that the difference between the first and second wheel speed signals is not within the predetermined tolerance range, transmitting, to the auxiliary controller, an abnormal signal.
