Abstract: The invention relates to a method for operating a reciprocating piston machine, particularly an internal combustion engine, having at least one piston rod that is hydraulically adjustable in length for setting a compression ratio, wherein the piston rod comprises a piston and a hydraulic cylinder for adjusting its length, wherein the piston with the hydraulic cylinder delimits at least one working chamber, through the fill level of which at least two switching positions of the piston rod are possible, wherein independently from the setting of the compression ratio the working chamber is at least partially filled and emptied as a function of at least one first predetermined requirement to effect an at least partial exchange of a hydraulic medium in the at least one working chamber.

Abstract: A method for producing control data for rule-based driver assistance for guiding a vehicle by a driver assistance system is provided. The method includes detection of values of at least one adjustment parameter for guiding the vehicle and/or a body parameter which at least partially characterizes body functions of a vehicle passenger. The method also includes detection of values of at least one input parameter which at least partially characterizes a driving scenario; determining at least one boundary condition for adjusting the at least one adjustment parameter according to the at least one input parameter based on the detected values; and emission of control data for guiding the vehicle, which takes into account the at least one boundary condition as a rule.
