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.
