Abstract

A system and method for reducing speed of a vehicle include determining whether or not there is a need for operator braking action, determining a stand-by braking torque when there is a need for operator braking action, determining a transition braking torque based on the stand-by braking torque and an automatic distance regulation (ADR) braking torque, and applying the transition braking torque to at least one wheel of the vehicle. The transition braking torque may be applied using friction brakes associated with wheels, respectively. The ADR braking torque is represented by an ADR braking request that is generated when an actual distance from the preceding vehicle in front becomes less than a set desired distance. The ADR braking request may be provided at an ADR controller.
