Predictive Cruise Control unveiled for trucks

March 27, 2009 Daimler Trucks North America showcased an innovative "Predictive Cruise Control (PCC)" system in the "Freightliner New Innovation Truck" study at the Mid-America Trucking Show last week. The PCC assistance system uses map and satellite-based route previews and saves substantial amounts of fuel. Unlike a conventional cruise control system that tries to maintain a preset speed, regardless of how the terrain changes, the PCC system looks for its route a mile in advance and adjusts engine output to the uphill and downhill gradients ahead. Based on this information, the on-board computer calculates the optimum speed to use the momentum of the truck to maximize fuel economy.
