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.
