Abstract
Methods for transitioning a braking system between primary and fallback modes are provided. A method in accordance with the present disclosure may include identifying a failure in the functionality of the primary braking system, and, upon identifying the failure, mitigating an abrupt increase in a pedal travel distance required to brake or otherwise decelerate the vehicle so as to provide smooth transition from a primary braking mode to a fallback braking mode. The mitigating the increase in the pedal travel distance may include initiating a transition to the fallback braking mode, activating at least one of a plurality of transition braking modes, and gradually increasing the pedal travel distance by deactivating at least one of the previously activated transition braking modes.
