Abstract: A vehicle includes a plurality of electronic brake system (EBS) controllers configured to detect at least one braking event, and a plurality of brake assemblies. Each brake assembly is coupled to a respective wheel of the vehicle and includes an enhanced smart actuator. The enhanced smart actuator further includes an electro-mechanical actuator, and at least one power circuit. The electro-mechanical actuator is configured to adjust a torque force applied to the respective wheel. The at least one electronic power circuit is configured to output a high-frequency switched high-power current drive signal that drives the electro-mechanical actuator. The EBS controllers control a first group of enhanced smart actuators independently from a second group of enhanced smart actuators that exclude the enhanced smart actuators of the first group.

Abstract: A vehicle includes a plurality of brake assemblies and a plurality of electrical power circuits. Each brake assembly includes an electro-mechanical actuator configured to adjust a torque force applied to a wheel of the vehicle. The electrical power circuits are located remotely from one another. Each power circuit is configured to drive a respective actuator. The vehicle further includes a first electronic brake system (EBS) controller and a second EBS controller. The first EBS controller is configured to output a first data command signal to control a first group of power circuits among the plurality of power circuits. The second EBS controller is configured to output a second data command signal to control a second group of power circuits among the plurality of power circuits. The second group excludes the power circuits from the first group.

Abstract: A vehicle includes a plurality of brake assemblies and a plurality of electronic brake system (EBS) controllers. The brake assemblies each include an electro-mechanical actuator configured to adjust a torque force applied to a wheel of the vehicle. The EBS controllers are located remotely from one another. Each EBS controller has integrated therein an electronic actuator driver unit that includes an electronic power circuit configured to drive at least one of the electro-mechanical actuators. A first EBS controller is configured to drive a first group of electro-mechanical actuators, and a second EBS controller is configured to drive a second group of electro-mechanical actuators that exclude the electro-mechanical actuators of the first group.

Abstract: A brake pedal assembly of a brake emulator includes a resiliently flexible arm constructed and arranged to include a flexibility that mimics, at least in-part, a pre-determined braking force profile. The flexible arm includes opposite first and second end portions and a pivot point disposed there-between.
