Abstract:
1. A system for electrical braking of a vehicle, comprising: a power bus coupled to a first driver associated with a first electromechanical actuator (EMA), wherein the power bus is coupled to a second driver associated with a second EMA, wherein the first EMA and the second EMA are associated with a wheel of the vehicle, and wherein the power bus provides braking power to the first EMA via the first driver and to the second EMA via the second driver; a normal braking command interface for providing a first braking signal to the first driver and a second braking signal to the second driver; an emergency/park brake interface for sending a first emergency/park braking signal to the first driver and a second emergency/park braking signal to the second driver, wherein the first emergency/park braking signal and the second emergency/park braking signal bypass the normal braking command interface; a driver bank comprising the first driver and the second driver, wherein the driver bank is in electrical communication with a power controller via a driver bank supply power bus; a sensor coupled to the driver bank supply power bus for measuring a current drawn by the driver bank, wherein the current is proportional to a braking force exerted by the first EMA and the second EMA on the wheel; wherein the power controller is coupled to the power bus for providing power to the first driver and the second driver in response to at least one of the first braking signal, the second braking signal, the first emergency/park braking signal, or the second emergency/park braking signal; and a second sensor disposed between a power source and the power controller, wherein the second sensor measures a current supplied to the power controller.
