Abstract: A method determines an inflection point OP of a parameter profile i, n which is representative of a component tolerance and a state of wear of a fuel pump. The fuel pump is provided for a fuel supply system for use in a device equipped with an internal combustion engine. The device being a passenger car, utility vehicle and/or a stationary or mobile power generator.

Abstract: A method for calibrating a fuel pump for use in a fuel supply system of a device having internal combustion engine includes determining a tolerance-conditioned and wear-conditioned deviation of the fuel pump with respect to its delivery behavior so that the calibration permits energy-consumption-optimized actuation of the fuel pump.

Abstract: A fuel delivery unit in a fuel tank includes a fuel pump drivable by an electric motor. The fuel pump has at least one suction jet pump for delivering fuel, the suction jet pump being operated by a propulsion jet that is deliverable by the fuel pump. The fuel pump is arranged in a swirl pot, which is fillable by the suction jet pump, and the fuel pump has a first outlet, through which fuel is deliverable to a consumer, and a second outlet openable or closable by a valve.

Abstract: An electronic controller for a locking device. The controller has an actuation unit having at least two switchable control states for actuating an electromechanical actuator, wherein the locking device can be locked in the first control state by the actuator and can be released in the second control state. The controller has a first deactivation device which is arranged upstream of the actuation unit in the signal flow and is configured in such a way that only the first control state can be blocked by the first deactivation device and the second control state cannot be influenced by the first deactivation device. The invention also relates to a steering wheel lock having a latching element, a counter-latching element in the force flux of a steering system and an electromechanical actuator which can move the latching element into engagement with the counter-latching element and is actuated by the described electronic controller.

Abstract: The average current consumption of an electronic apparatus is determined in that an energy store C is repeatedly charged and discharged across the apparatus 1 between a set upper threshold value Uso and a set lower threshold value Usu during a typical operating sequence of the apparatus 1 and within a set measuring time T. The number N of charging processes occurring within the measuring time T is counted and the average current consumption is calculated therefrom while taking into account set values.
