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; and

    a sensor coupled to the power bus for measuring a current at a single location of the power bus, wherein the current is proportional to a braking force exerted by the first EMA and the second EMA on the wheel.
