Cruising with precision

摘要

MerCedeS-BenZ made a rather bold claim when it said its Predictive Powertrain Control (PPC) has the ability to slash operator's fuel bills by up to 5%. The system, available on both the New Actros and Antos (currently only the OM471 engine, but OM470 will follow later in the year), uses digital 3D GPS mapping to read the road ahead. Working in conjunction with the cruise control, it interacts with the Powershift automated transmission to adapt the truck's driving style to the given topography. Because it knows exactly what gradient it's about to tackle, it accelerates, decelerates and applies EcoRoll accordingly.
