Freightliner's Predictive Cruise Control Saves Fuel

摘要

In July, Freightliner will begin shipments of heavy duty trucks that feature its optional Predictive Cruise system that anticipates changes in road grades and automatically adjusts the vehicle's speed to maximize fuel efficiency.rnThe feature employs a scaled-down GPS navigation device that keeps track of current position and, using a map provided by Navteq that has been enhanced with slope information, varies the truck's speed, within 6% of the set speed, based on the upcoming road profile. The system looks at road slope data for more than a mile in front of the vehicle.
