Abstract: Systems and method are provided for controlling a vehicle. In one embodiment, a method includes: receiving, by a processor, at least one of state health and performance information associated with at least one vehicle actuator; processing, by the processor, the state of health and performance information to determine an acceleration value; and controlling the vehicle based on the acceleration value.

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 vehicle is provided. The vehicle includes a brake-by-wire sub-system, which includes a controller. The controller receives a request to enter a service mode. In response to the request to enter the service mode, the controller determines whether a vehicle is in a stable state based on comparing at least one system condition against at least one threshold. When the vehicle is in the stable state, the controller causes the brake-by-wire sub-system to enter into the service mode. Further, the controller monitors the at least one system condition against predefined parameters to determine that the vehicle is maintaining the stable state while in the service mode.

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 assembly of a brake-by-wire system of a vehicle includes a support structure, a brake pedal pivotally engaged to the support structure at a first pivot axis, and a brake pedal emulator assembly. The brake pedal emulator assembly extends between and is pivotally engaged to the brake pedal and the support structure at respective second and third pivot axis. The brake pedal emulator assembly includes a brake pedal emulator and an adjustment mechanism aligned along a centerline intersecting the second and third pivot axis. The brake pedal emulator is constructed and arranged to displace axially when the brake pedal is actuated, and the adjustment mechanism is constructed and arranged to adjust axial displacement.

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.

The brake assemblies includes a first brake assembly integrated with a smart actuator unit including a first actuator controller and a first electro-mechanical actuator that is configured to adjust a brake force applied to a first wheel coupled to the first brake assembly. A second brake assembly excludes an actuator controller and has installed therein a second electro-mechanical actuator that is configured to adjust a brake force applied to a second wheel coupled to the second brake assembly. At least one electronic actuator driver unit is remotely located from the first and second brake assemblies, and is configured to output a high-power signal that drives the first and second electro-mechanical actuators in response to receiving a digital command signal from the first actuator controller.
