In a method for controlling an internal combustion engine, in particular a diesel internal combustion engine, at least one variable is formed on a cylinder-specific basis, which variable characterizes a respective profile of a combustion in an associated combustion chamber, and the control of cylinder-specific fuel injection parameters is influenced as a function of said at least one variable which characterizes the combustion profile.

A method for evaluating an ion current signal of a self-igniting internal combustion engine, with the ignition shift being derived from the time shift of the local maximum in the curve of the ion current signal relative to an injection point in time. Similarly, continuous injection in a cylinder can be detected when the ion current signal is integrated and evaluated in terms of area and/or when the position and/or height of the maximum of the ion current signal are evaluated. Carbon formation can be detected by an evaluation of the time curve of the ion current signal following an injection. For example, the parameters of the main injection can be controlled as a function of an evaluation of the measured ion current following a preinjection. When a continuous injection is detected, injection can be suppressed at least in those cylinders in which continuous injection was detected.

A motor vehicle electrical system has an electrical machine with an on-board power supply generator function. The electrical machine can be operated, in a first mode, as an on-board power supply generator, having a regulator for setting the excitation current for the electrical machine, and having an electrical load having a comparatively high power consumption, for example a heating device for an exhaust gas catalytic converter. A changeover switch, by means of which an output of the electrical machine can optionally be connected to an on-board power supply cable or to the load, as well as a control unit for controlling the regulator and changeover switch optionally in the first mode or a second mode, is provided so that the electrical machine is connected to the on-board power supply and the regulator regulates the operating voltage at an on-board power supply voltage. Alternatively, the electrical machine is connected to the load and the regulator regulates the operating voltage at a higher nominal value. In addition to these two functions, a third function as a starter motor is provided for the electrical machine.
