The invention relates to a device for monitoring an exhaust gas catalytic converter in the exhaust system of an internal combustion engine. Provided for this purpose is a measuring arrangement (10) which is arranged in the exhaust system (A) in such a way that, in most of the operating range of the internal combustion engine (1), it assumes a temperature which correlates with a temperature of the exhaust gas catalytic converter (4). According to the invention, the measuring arrangement (10) has a temperature-sensitive component with a characteristic component parameter which is designed as a temperature-dependent component parameter which changes abruptly at a predefined transition temperature or in a predefined transition temperature range or as a temperature-dependent component parameter which changes continuously as a function of the temperature in a predefined manner. A control and evaluating unit (7) which is connected to the measuring arrangement (10) can measure the characteristic component parameter and/or a change thereof and can correlate this with an ageing state of the exhaust gas catalytic converter (4).

The invention relates to devices and/or methods for determining the availability of electric energy in two-energy accumulator vehicle electric systems, in which both energy accumulators, particularly batteries, can be connected to one another via a D.C. converter. The required electric energy is generated by means of a generator that is driven by a vehicle engine. The customary consumers are connected to a first consumer battery circuit (10, 24). Additional consumers, for example, high-current consumers, particularly the starter, are connected to the second battery circuit (11, 29). A control device, for example, a controller that is equipped with a microprocessor determines the availability of the electric energy and occurring faults while evaluating different algorithms and takes over the necessary controls and signalings. The algorithms include threshold value statements for providing the electric energy (SOCS) and threshold value statements for identifying the system faults (SOHS).

Die Erfindung betrifft ein mechanisches Stabilisierungssystem für Tandemachsen, Drillings- und/oder Vierlingsachsen im Kraftfahrzeugbau mit zwei, drei oder vier hintereinander angeordneten, am Fahrzeugaufbau (5) beweglich gelagerten radtragenden Achsen (11,12) oder Achsteilen. Dazu weist jede Achse pro Radseite eine gelenkig gelagerte Koppelstange (21-24) auf. Pro Fahrzeugseite sind die Koppelstangen paarweise mit einer Wippe (31,32) gekoppelt. Die Wippen stützen sich an den freien Ende eines U-Stabilisators (40) ab. Mit der vorliegenden Erfindung wird ein mechanisches Stabilisierungssystem für Tandemachsen, Drillings- und/oder Vierlingsachsen entwickelt, bei dem die Gewichtskraft des Fahrzeugaufbaus und die auf diesen Aufbau wirkenden Seitenkräfte unabhängig voneinander am Fahrwerk abgestützt werden.

Die vorliegende Erfindung betrifft ein Verfahren zur Auswertung eines Ionenstromsignales einer selbstzündenden Brennkraftmaschine, wobei aus dem zeitlichen Versatz eines lokalen Maximums im Verlauf des Ionenstromsignales gegenüber einem Einspritzzeitpunkt der Zündverzug abgeleitet wird. Ebenso kann eine Erkennung einer Dauereinspritzung in einem Zylinder erfolgen, indem das Ionenstromsignal integriert und hinsichtlich der Fläche bewertet wird und/oder indem die Lage und/oder Höhe der Maxima des Ionenstromsignales ausgewertet werden. Bei einer erkannten Dauereinspritzung kann die Einspritzung zumindest in den Zylinder unterbunden werden, bei dem eine Dauereinspritzung erkannt wird.

The invention relates to a method for controlling a plurality of components (10, 15, 16) in a form of transport provided with a control appliance (1) having a first control program (20) for a first component (15) and a second control program (21) for a second component (16). Each control program (20, 21) carries out a temporally limited process in order to control the associated components (15, 16). Each process is defined by a starting point and an end point. The starting point is defined by a triggering event. Processes (21, 22, 25, 26, 30) for components (15, 16) that can be controlled in parallel are run on the same control appliance (1). According to the invention, a priority marker is respectively associated with the processes (21, 22, 25, 26, 30), and at the starting point of the first process, it is checked whether another running process has already been executed. If this is the case, the first process is entered in a queuing memory (13), and at the end of a running process, either a natural end or an interruption, said process with the highest priority begins with the control of the associated components. The priority marker is dynamically allocated, and a different priority is allocated to each process in different driving or operating situations of the form of transport.
