Abstract: A method for operating a generator for an internal combustion engine of a vehicle having a starting operating mode and a start-stop operating mode, a torque of the generator being delimited in the starting operating mode, including: detecting an operating mode of the vehicle, and deactivating a delimitation of the torque of the generator if the detected operating mode corresponds to the start-stop operating mode.

Abstract: A method for detecting a rotation of a rotor of a generator, which includes measuring the voltage induced in the rotor for the generator voltage in the case of an emergency start with an inactive closed-loop controller; and detecting the rotor rotation with the aid of the induced voltage. When a rotation is detected, the control circuit is activated and the rotation is determined from the phase voltage.

Abstract: A method for protecting an automotive generator from overheating, in which a predefined limiting characteristic curve, related to a base temperature and describing a maximally allowed excitation current value, is shifted as a function of a calculated temperature, a static offset is ascertained in a first step and a dynamic offset is ascertained in a second step during ascertainment of the calculated temperature, the static offset is ascertained as a function of the excitation current and the dynamic offset is ascertained as a derivation of the excitation current over time.

Abstract: Methods for ascertaining the combustion noises of an internal combustion engine need only a structure-borne noise sensor and may be carried out using little computing power.

Abstract: A method and a device for controlling an internal combustion engine, in which a noise variable is compared to a setpoint value, and an actuating variable is specified based on the comparison. The noise variable is computed using a weighted summation of at least two characteristics.

Abstract: A device and a method for controlling and/or regulating an internal combustion engine, in particular an internal combustion engine having direct injection. A regulation adjusts a combustion state variable, that characterizes the combustion state, to a setpoint value. A control and/or a regulation influences a torque variable that characterizes the torque of the internal combustion engine and/or the noise variable that characterizes the noise of the internal combustion engine, using a control variable.

Abstract: A method is described for determining the angle-of-rotation position (?) of a shaft of an internal combustion engine, in particular a crank angle (?) of a crankshaft, information at least about incremental angles of rotation (??) of the shaft and running times (T) for each incremental angle of rotation (??) being detected on the basis of signals which indicate the rotation of the shaft and are spaced with intervals between them, and stored at least temporarily the instantaneous angle-of-rotation position (?) being determined in the period of time between two signals by extrapolation of the angle-of-rotation position (?) thus detected, taking into account at least one angular velocity ({overscore (?)}) and/or change in angular velocity (?{overscore (?)}) extrapolated from the stored information. In addition, a corresponding device is also described.
