1. A brake system, comprising:
- a first electromechanical brake actuator (EBA) proximate a first wheel, the first EBA including a first power device configured to effectuate braking of the first wheel, and first electronics to generate a first drive signal for the first power device; and
a first brake control unit (BCU) for converting a brake command signal into a first EBA control signal for the first EBA;
wherein the first electronics in the first EBA are configured to convert the first EBA control signal into the first drive signal that is applied to the first power device to effectuate the braking of the first wheel,wherein the first EBA is configured to communicate with the first BCU through a remote data concentrator (RDC), andwherein the RDC is also in communication with a second EBA,the second EBA proximate a second wheel of an aircraft, the second EBA including a second power device configured to effectuate braking of the second wheel, and second electronics to generate a second drive signal for the second power device; and
a second BCU for converting the brake command signal into a second EBA control signal for the second EBA, wherein the second electronics in the second EBA are configured to convert the second EBA control signal into the second drive signal that is applied to the second power device to effectuate the braking of the second wheel.

Abstract
A brake system of a vehicle includes a plurality of electromechanical brake actuators (EBAs) proximate the wheels of the vehicle. Each EBA includes a power device for effectuating braking of an associated wheel, and electronics to generate a drive signal for the power device. The brake system may further include at least one brake control unit (BCU) for converting a brake command signal into a control signal for each EBA. The electronics for each EBA may be configured to convert the corresponding control signal into the drive signal that is applied to the power device to cause movement of the power device and effectuate braking of the vehicle.
