    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.
