Abstract: A brake pedal assembly of a braking system for a vehicle includes a brake pedal pivotally engaged to a support structure at a first pivot axis. A linkage of the brake pedal assembly is pivotally engaged to the brake pedal at a second pivot axis spaced from the first pivot access by a distance. An adjustment mechanism of the assembly is carried by the brake pedal and is constructed and arranged to alter the distance.

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: Systems and methods are provided testing a vehicle braking system. The method includes determining a nominal brake system parameter of the brake system during a braking operation. A first testing brake operation is performed and a first brake system parameter is determined based on the first testing brake operation. A tested brake system parameter is determined based on the first testing system parameter and the tested brake system parameter is compared to the nominal brake system parameter. A brake system compliance suspicion value of the vehicle braking system is then set based on the comparison.

Abstract: A vehicle is provided. The vehicle includes a vehicle system. The vehicle system includes a brake-by-wire portion, which also includes a controller. The controller can cause a forced coastdown of the vehicle. The forced coastdown includes performing analyzing conditions of the vehicle system to determine whether the vehicle is in a stable state and to determine an amount of energy available to the vehicle system and automatically applying the forced coastdown when the vehicle is not in the stable state and the amount of energy is less than or equal to a threshold for continued manual operation of the vehicle. The forced coastdown also includes utilizing brake pressure to reduce a speed of the vehicle.

Abstract: A vehicle includes a plurality of brake assemblies configured to control braking of a respective wheel of the vehicle. 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.

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.
