Claim 0:
1. A brake system comprising:
a main brake system having a control over providing a braking force to a wheel of a vehicle;
an auxiliary brake system configured to provide the braking force to the wheel upon a malfunction at the main brake system;
a signal bus extending between the main and auxiliary brake systems and configured to transmit, between the main and auxiliary brake systems, a malfunction status signal indicating a presence or absence of the malfunction at the main brake system; and
a communications unit configured to transmit and receive, between the main and auxiliary brake systems, operation state information indicating a cause of the malfunction at the main brake system,
wherein the auxiliary brake system is configured to perform:
detecting, based on the malfunction status signal transmitted via the signal bus, the presence of the malfunction at the main brake system;
in response to detecting the presence of the malfunction at the main brake system, preparing to provide the braking force to the wheel;
after starting preparing to provide the braking force to the wheel, determining, based on the operation state information transmitted from the communication unit, whether the main brake system has lost a braking function; and
in response to determining that the main brake system has lost the braking function, taking over, from the main brake system, the control over providing the braking force to the wheel.
