Abstract: An apparatus comprising a first circuit module and a second circuit module. The first circuit module may be configured to communicate with a vehicle over a first bus. The first circuit module generates one or more first brake control signals in response to one or more command inputs and is powered by a first power source. The first brake control signals provide primary control of hydraulic flow and pressure to control one or more brake calipers in a vehicle. The second circuit module may be configured to communicate with the vehicle over a second bus. The second circuit module generates one or more second brake control signals in response to said one or more command inputs and is powered by a second power source. The second brake control signals provide secondary control of hydraulic flow and pressure to control the one or more brake calipers. The first and the second circuit modules are fabricated on a single printed circuit board to provide redundant control of the one or more brake calipers.

Abstract: An apparatus comprising a first circuit module and a second circuit module. The first circuit module may be configured to communicate with a vehicle over a first bus. The first circuit module (i) generates one or more first brake control signals in response to one or more command inputs and (ii) is powered by a first power source. The first brake control signals provide control of hydraulic flow and pressure applied to a first one or more brake calipers in a vehicle. The second circuit module may be configured to communicate with the vehicle over a second bus. The second circuit module (i) generates one or more second brake control signals in response to the one or more command inputs and (ii) is powered by a second power source. The second brake control signals provide control of hydraulic flow and pressure applied to a second one or more brake calipers.
