Abstract: A method for operating an internal combustion engine is described in which a combustion air ratio (λ) is determined and used to determine a deviation of this combustion air ratio from an in particular default or determined set point combustion air ratio. Spontaneous ignition of the internal combustion engine are detected based on the determined deviation (Δλ) and used to control the operation of the engine.

Abstract: A motor vehicle servomotor arrangement includes an electric motor with a stator, a rotor and brushes, as well as a controller with a signal input and a signal output that is connected to the electric motor. The controller is configured to transmit a control signal to the electric motor in response to an input signal supplied via the signal input by a unique function. The controller is configured to modulate the control signal in such a way that different control signals are output upon successive identical input signals within predefined input signal ranges and/or time-variant control signals are output upon identical input signals.
