Methods for selection of operating mode and control system for an internal combustion engine

摘要

For the purpose of selecting the operating mode in the case of an internal combustion engine (6) which can be operated in several different operating modes (lambda-1-regulated operation, homogeneous-lean operation, layered-lean operation), the driver behaviour and/or the driving situation is classified and the result taken into consideration during selection of the operating mode. In the case of an internal combustion engine (6) with a controllable gearbox (7), the operating mode and gearbox setting are chosen such that the requested torque can be produced while keeping the fuel consumption of the internal combustion engine (6) to a minimum. To this end, in a control system, an operations control unit (5) for the internal combustion engine (6) and a gearbox control unit (4) for the gearbox exchange suitable signals via communications lines (17, 18, 25).
