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