    Abstract: 1. Verfahren zur Positions- oder Geschwindigkeitsbestimmung eines Ankers. 2.1. Bei einem elektromagnetischen Aktuator mit einem zwischen zwei Elektromagneten hin- und herbewegbaren Anker wird die Position oder Geschwindigkeit des Ankers üblicherweise mittels eines Wegsensors ermittelt, wobei die Genauigkeit der Positions- oder Geschwindigkeitsbestimmung vom verwendeten Wegsensor abhängig ist. Das neue Verfahren zur Positions- oder Geschwindigkeitsbestimmung des Ankers soll auch bei der Verwendung preisgünstiger Sensoren genaue Ergebnisse liefern. 2.2. Dies wird durch die Verwendung eines neuronalen Netzwerks erreicht, das in einer Lernphase mit einem den genauen Positions- oder Geschwindigkeitsverlauf des Ankers repräsentierenden Referenzsignal und mit mehreren momentane Betriebsparameter der Brennkraftmaschine repräsentierenden Eingangsgrößen trainiert wird und das in einer an die Lernphase anschließenden Betriebsphase aus aktuellen Eingangsgrößen unter Verwendung des trainierten neuronalen Netzwerks ein Meßsignal generiert, das dem Positions- oder Geschwindigkeitsverlauf des Ankers entspricht. 2.3.

    Abstract: The invention relates to an actuator device which holds an actuator, for actuating a gas exchange valve of an internal combustion engine for instance, in an end position by means of a coil. The aim of the invention is to switch said actuator device into the other end position in time. To this end, the impingement of the coil with voltage is stopped a certain period of time tk before the moment when the actuator is released from the end position. The period of time tk is selected according to the supply voltage of the actuator device and/or of the coil current during holding in the end position. It is possible to adapt the period of time tk.

    Abstract: An internal combustion engine has a plurality of cylinders to each of which at least one inlet valve (30) and at least one exhaust valve (31) are assigned. A valve gear (32, 33) is respectively provided for controlling the inlet valve (30) and the exhaust valve (31). The valve control time (VSZ_IN) for the inlet valve of a cylinder is calculated at least one segment later than the valve control time (VSZ_EX) for the exhaust valve of the same cylinder. A segment is determined by the phase angle between the upper dead centers of two pistons of cylinders which directly follow one another in the ignition order.

    Abstract: The invention relates to an electronic device for controlling gas exchange valves in an internal combustion engine with variable valve timing, which makes it possible to fully close at least the intake valves and which is fitted with means for detecting the amount of air suctioned by the internal combustion engine and means for detecting valve lift. The electronic control device changes the opening function during displacement starting from a totally closed position of the intake valve in order to open the inlet valve, detect the extent to which the valve has being opened, whereupon the amount of air is detected and uses said extent as reference for determining the actual cross section of the aperture.

    Abstract: A control device for an internal combustion engine comprising fuel injection control means for controlling the amount of fuel that is injected from a fuel supply device for supplying fuel to an internal combustion engine and fuel injection timing, and variable valve control means for changing in a continuous or stepped fashion at least one of an open timing, a close timing and a valve lift of a suction valve or an exhaust valve for closing a combustion chamber of said internal combustion engine, wherein said fuel injection control means is constructed so as to control at least either of the amount of fuel that is injected based on the controlled variable of said variable valve control means or the injection timing. According to the present invention, it is possible to reduce pumping loss so as to improve fuel efficiency because an air volume can be controlled by the variable valve mechanism. In addition, the invention makes it possible not only to atomize fuel injected into the combustion chamber by opening said suction valve in such a manner as to cause shock waves in said combustion chamber but also to achieve stable combustion without deteriorating exhaust gas.
