The advanced and predictive cruise control PPC integrates a driving style adapted to the landscape into the automatic gearshift and, in conjunction with the precisely tuned gearshift strategy, enables noticeable fuel savings. With the new, optimised generation, the system is now even more powerful. PPC guides you along country roads, takes junctions and roundabouts into account and is networked with the Adaptive Cruise Control. It can already be used from a speed of 15 km/h.
Optimised and further developed for the future of intelligent driving, the predictive cruise control PPC is a prime example of the digital networking of buses and coaches. It draws on the topographical data of more than 95 per cent of motorways, trunk roads and interurban roads in many European countries. Via GPS, PPC always knows the current position of the vehicle and its route ahead with its altitude profile or gradient. Based on this data, the current and preset speed, the current vehicle mass and the data on engine power, torque and transmission, PPC regulates the speed and influences the shift strategy. EcoRoll is also used in the process: In worthwhile cases, the technology selects the neutral position of the transmission and thus allows the vehicle to roll longer without drag losses to save fuel. The engine continues to idle. Afterwards, the technology shifts back into gear.
