Predictive Powertrain Control links the vehicle’s GPS data with precise digital 3D maps, thereby detecting upcoming uphill and downhill gradients on the road and optimising gearshift times, gearshift jumps, cruise control speed and EcoRoll phases on this basis. The system also includes curves, junctions and the speed limits stored in the map data and reacts accordingly. In combination with the precisely coordinated gearshift strategy, this enables fuel savings of up to 5 %. Predictive Powertrain Control integrates the driving modes as well as the wear-free brake and extended Top Torque**. It also recognises the driver’s wish to turn and initiates an EcoRoll phase in good time.
In addition to the course of the road with uphill and downhill gradients ahead, the system also identifies junctions, roundabouts and traffic signs integrated in 3D maps. On the basis of this data, Predictive Powertrain Control optimises shift points, gear steps and the set cruise control speed. What's more: the vehicle's kinetic energy is used to avoid unnecessary acceleration, shifting or braking. This means that cruise control can be used in virtually all driving situations. This relieves the driver's workload and contributes to a fuel-efficient driving style on A and B roads, too. Predictive Powertrain Control can be used in conjunction with cruise control at speeds between 25 and 90 km/h.
