摘要： The invention concerns a procedure for determining the composition of a fuel mixture from a first fuel and a second fuel or for determining the quality of a fuel for operating a combustion engine with at least one cylinder pressure sensor in at least one cylinder of the combustion engine for determining the pressure history during a combustion process and a cylinder pressure based motor regulation for regulating the load and the combustion situation of the combustion engine. It is thereby provided that the determination of the composition of the fuel mixture or the quality of the fuel takes place with the aid of regulator information of the cylinder-pressure-based motor regulation. The procedure enables the continuing determination of the composition of the fuel mixture and the quality of the fuel at cylinder-pressure-based motor regulations without additional components as for example an ethanol sensor.

摘要： A method for controlling a compression-ignition internal combustion engine includes the following steps: predefining a setpoint combustion point for the compression-ignition internal combustion engine, predefining a calculation model for calculating a probable deviation of a future cycle of the internal combustion engine from the predefined setpoint combustion point while taking an ascertained actual combustion point of a completed cycle of the internal combustion engine into consideration, predefining a mean deviation for the internal combustion engine, operating the internal combustion engine for a first cycle and ascertaining an actual combustion point of the first cycle, calculating a probable deviation of a second cycle, which occurs after the first cycle, of the internal combustion engine from the predefined setpoint combustion point, comparing the calculated probable deviation of the second cycle to the predefined mean deviation, and ascertaining at least one operating variable for operating the internal combustion engine at least during the second cycle as a function of the comparison. In addition, a control device for controlling a compression-ignition internal combustion engine is described.

摘要： A method for operating an internal combustion engine, especially an internal combustion engine that is operable, at least in a part-load range, in an operating mode with auto-ignition, in which, at an abrupt change in load and/or at a changeover between an operating mode with auto-ignition and an operating mode without auto-ignition, a parameter of the combustion process correlating with the combustion noise is adapted stepwise over a plurality of combustion cycles from a first parameter value before the abrupt change in load or the changeover to a second parameter value after the abrupt change in load or the changeover, by influencing a combustion position of the combustion process.

摘要： A method for rollover stabilization of a vehicle in critical driving situations, in which a rollover stabilization algorithm intervenes in the driving operation in a critical situation, using an actuator in order to stabilize the vehicle. Different loading states of the vehicle may be taken into consideration in that the vehicle mass as well as the characteristic speed and the ratio of the contact patch forces of the wheels are ascertained, and the rollover stabilization algorithm is executed as a function of the vehicle mass and the estimated vehicle center of gravity.

摘要： In a method for stabilizing a vehicle in extreme driving situations, in particular when understeering while cornering, multiple wheels are decelerated in order to reduce the driving speed. A maximum cornering force of the wheels and thus a minimal curve radius may be achieved if in particular the rear wheels are decelerated and a higher braking torque is applied on the rear wheels than on the front wheels and in the process in particular the outside front wheel remains highly underdecelerated.
