Abstract
A method for automatically controlling the downhill speed of a machine. The method includes establishing a target machine speed based on a current machine speed and determining whether at least one trigger condition including a grade greater than a predetermined threshold has been satisfied. If satisfied, the method activates a control system to control at least one of a powertrain retarder and a change in a transmission gear to prevent exceeding the target machine speed.
