Abstract: A vehicle with a fault tolerant electronic brake-by-wire (BBW) system includes a plurality of brake assemblies that control braking of a respective wheel of the vehicle. The brake assemblies include a first brake assembly and a second brake assembly. The first brake assembly is integrated with at least one enhanced brake actuator assembly including a first electronic actuator driver circuit in signal communication with a first electro-mechanical actuator. The first brake assembly is configured to adjust a brake force applied to a first wheel of the vehicle. The second brake assembly is integrated with at least one enhanced smart brake actuator assembly including a first actuator controller in signal communication with a second electronic actuator driver circuit. The second electronic actuator driver circuit is in signal communication with a second electro-mechanical actuator that is configured to adjust a brake force applied to a second wheel of the vehicle.

Abstract: A brake pedal apparatus for actuating a vehicle brake assembly includes a stationary structure, a brake pedal emulator assembly, and an emulator override device. The brake pedal emulator assembly includes a brake pedal operatively engaged to the stationary structure, and a brake pedal emulator operatively engaged between the stationary structure and the brake pedal along a centerline. The brake pedal emulator is configured to electrically operate the brake assembly. The emulator override device includes a mechanical linkage operatively engaged to the brake assembly, and a latch configured to selectively connect and disconnect the mechanical linkage from the brake pedal emulator assembly. The mechanical linkage is configured to mechanically operate the brake assembly via at least in-part movement of the brake pedal along the centerline.

Abstract: A brake pedal emulator for a brake-by-wire system of a vehicle extends and connects between a support structure and a brake pedal operatively engaged to the support structure. The brake pedal emulator includes a hydraulic cylinder having a magneto-rheological hydraulic fluid and an electrical element configured to carry an electrical current for controlling a viscosity of the magneto-rheological hydraulic fluid and thereby controlling a first force exerted by the hydraulic cylinder when actuated by the brake pedal.

Abstract: A vehicle includes a plurality of brake assemblies, and a brake request input device. Each brake assembly is coupled to a respective wheel of the vehicle and is configured to control braking of the respective wheel. The brake request input device is configured to output an electronic brake request signal indicating a request to brake at least one of the wheels. Each brake assembly has integrated therein an enhanced smart actuator unit that includes an electronic actuator controller configured to control a braking torque applied to the respective wheel in response to receiving the brake request signal.

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.
