Predictive Cruise Control System
Posted on Mar 27, 09 07:50 AM PDT
Daimler Trucks North America recently showcased the innovative "Predictive Cruise Control (PCC)" system that relies on both map and satellite-based route previews in order to save a rather substantial amount of fuel across the organization. It does things differently from a conventional cruise control system which attempts to maintain a preset speed no matter what the terrain is like, as the PCC system will prefer to search for an optimal route a mile in advance while adjusting engine output to the uphill and downhill gradients ahead. All this information will be processed by the on-board computer which then calculates the optimum speed to use the momentum of the truck to maximize fuel economy.
