A method for initial calibration of a sensor for a driver assistance system of a vehicle, comprising the steps of: detecting a trajectory of the vehicle by way of a reference device disposed externally to the vehicle; ascertaining a sensor axis of the sensor; ascertaining a travel axis of the vehicle from the detected trajectory; and ascertaining an angle between the sensor axis and the travel axis.

Method for initial calibration of a sensor for a driver assistance system of a vehicle

In a method for operating a forced-induction internal combustion engine of a motor vehicle with variable compression, provision is made that the variable compression is pilot-controlled in such a way that a selected compression is established as a function of combustion efficiency and of the mechanical stress on components of the internal combustion engine, such that elevated compression is provided in the naturally aspirated range and/or decreased compression is provided in the forced-induction range. The variable compression is generated by phase shifting of a camshaft of the internal combustion engine, or by cam switching by way of a variable valve train.
