Abstract

A method for intelligent active engine braking using full authority active fuel management based on vehicle speed and brake pedal position. The method includes determining if the tow mode of the vehicle has been selected and enables all engine cylinders to ensure maximum engine braking capacity is available. When vehicle tow mode is not selected then the method varies engine braking capacity by disabling one or more cylinders based on the vehicle speed and brake pedal position.
