The improved PPC cruise control also avoids unnecessary braking, accelerating or shifting gears on winding interurban journeys and thus supports the driver in wear-free and fuel-saving driving. If PPC is activated on an interurban route and a coasting situation is detected, the target speed and the reason for the speed reduction (bend, roundabout, right of way, stop point) are displayed in the instrument binnacle. Based on the stored maps, PPC automatically reduces the speed when entering towns and villages, as well as before country road bends with a tight radius or obstacles such as roundabouts and stop or right-of-way points. The driver can adjust the deceleration behaviour to route events in five stages to suit the current application, from a dynamic to an emphatically economical driving style. Likewise, it can set a curve speed factor in five steps to take into account boundary conditions such as lane width and verge construction. In this case, the range extends from the particularly passenger-friendly to a dynamic variant, for example when travelling without passengers. The PPC interventions can be overridden at any time by the driver via their own brake intervention or operation of the accelerator pedal, to retain complete control. After manually driving through the obstacle, they have the option of switching the cruise control back on, which then accelerates back to the set speed. In any case, the driver remains fully responsible for the safety of their passengers. The interaction between PPC and Adaptive Cruise Control can also further improve fuel efficiency: ACC continuously provides the system with information about vehicles ahead so that the intelligent cruise control system can ideally plan gear changes and speed progression and make the best possible use of the vehicle's momentum for coasting phases. The new, optimised generation of Predictive Powertrain Control thus further expands the recognised advantages of the assistance system and extends the area of application from motorways and trunk roads to almost all non-urban roads in Europe. This step increases the overall economy of the coach. With the reduction in consumption, CO2 emissions are also reduced.
