    摘要： A method and a device for controlling operating sequences in a vehicle using at least one control unit having at least one non-volatile memory element, control being performed as a function of the respective vehicle version and/or control unit version, and the respective functions are selected during function selection by defining an identifier according to the version used, at least one predefinable data record and/or program code in the memory element corresponding to the selected functions, and the data record and/or program code being selected from a plurality of data records and/or program codes. The plurality of data records and/or program codes is generated during a version selection, the identifier containing configuration parameters, and the configuration parameters being used for determining the data record and/or the program code, the respective identifier, i.e. the configuration parameters being used for the selection of the version and the selection of the function.

    摘要： A method is proposed for diagnosing the drive voltage for a piezoelectric actuator of an injector, in which the drive voltage is measured for the individual phases of the injection procedure. With respect to each control phase, a corresponding tolerance band is provided, which is set using the setpoint value of the drive voltage. The tolerance ranges are established as a function of operating and/or environmental conditions. If, for the individual drive cycles, the corresponding tolerance ranges are not reached, then, in response to repeated measurement, these erroneous measurements are counted. When a preestablished number for the erroneous measurements is exceeded, then an ongoing error is diagnosed. If, after a certain time, the number is not exceeded, then the counter is reset. In the case of an error, the error storage unit can be reset using a maintenance plug-in device during maintenance.

    摘要： In a method for operating an internal combustion engine, in particular of a motor vehicle, the internal combustion engine is controlled by at least one drive variable, and an instantaneous torque output by the internal combustion engine is determined from a performance variable of the internal combustion engine that differs from the drive variable.To determine the instantaneous torque, an exhaust-gas temperature of the internal combustion engine is used as performance quantity that differs from the drive variable.

    摘要： A method is provided for operating an internal combustion engine 10 in overrun condition, which method includes the steps of: release of a monitoring of a control signal for a power actuator of the internal combustion engine when predetermined release conditions have been satisfied, which include the exceeding of a release rotary speed of the internal combustion engine; after the release, comparing a control signal for the power actuator of the internal combustion engine to a threshold value, and triggering an error response if the control signal exceeds the threshold value. The method provides that the release speed is varied as a function of the intervention of an idling speed control in the formation of the control signal. Also provided is a control unit which controls such a method.
