Abstract: A control device and a method for operating a control device which contains function modules, a scheduler and a priority manager. The control device is connected via data lines to a system to be controlled. The priority manager assigns to the modules modifiable priorities which are then taken into account when the modules are activated by the scheduler.

Abstract: A method detects mass flows to the intake manifold of an internal combustion engine having a device for controlling the air supply to the intake manifold and having a sensor for detecting the intake manifold pressure and having a control apparatus for evaluating a trace of the intake manifold pressure. In the context of the method, when the internal combustion engine is switched off, the supply of air to the intake manifold is reduced in a predetermined manner and the trace of the intake manifold pressure, which adjusts thereupon, is evaluated for detecting the mass flows.

Abstract: An internal combustion engine, in particular for a motor vehicle, in which fuel may be injected into a combustion chamber during an intake phase in a first mode of operation or during a compression phase in a second mode of operation, and in which exhaust gases may be sent to a catalytic converter. A control unit determines a temperature difference between an actual exhaust gas temperature and a setpoint exhaust gas temperature at an operating point having a low exhaust gas temperature. In addition, at least one additional injection after combustion is implemented by the control unit as a function of the temperature difference.

Abstract: An internal combustion engine for a motor vehicle. In the internal combustion engine, fuel is injected directly into a combustion chamber and is burned during an intake phase in a first mode of operation and during a compression phase in a second mode of operation. Exhaust gas formed by combustion may be sent to a catalytic converter. A controller may cause additional fuel to be injected following combustion in the second mode of operation. The controller may also cause the temperature of the exhaust gas to be measured in or downstream from the catalytic converter and compared with a threshold value.

Abstract: An internal combustion engine, especially for a motor vehicle, is described, which is provided with a storage catalytic converter which can be loaded with and unloaded of nitrogen oxides.

A sulphur content of the fuel used can be determined by the control apparatus from sequential states of deterioration (points 13).

Abstract: A method for determining mass flows into the inlet manifold (3) of an internal combustion engine, with means (5, 6, 9), for controlling the air intake into the inlet manifold (5, 6, 9), means (4), for determining the inlet manifold pressure and means (11) for evaluating the inlet manifold pressure curve, is disclosed. Within the disclosed method, the air intake into the inlet manifold, on switching off the internal combustion engine, is reduced by a set amount and the curve for the inlet manifold pressure thus produced is evaluated for the estimation of the mass flows and a leak in the inlet manifold proven by an increased rate of pressure change.

A conclusion can be drawn as to the operability of the catalytic converter (12) by the control apparatus (18) from NOx emissions measured downstream.

Abstract: A computer system for controlling the operation of a drive of a motor vehicle includes a plurality of different predetermined components each including at least one functional unit. Such components include a first component representing the motor vehicle as a whole and second component representing the drive. A plurality of interfaces is interposed between these components, being operative for transmitting data between such components. At least one storage stores information concerning such components and interfaces. The functional units mentioned above and the vehicle as a whole are controlled by controlling the above-mentioned components inclusive of the first component. In performing the control, request signals and inquiry signals are generated and transmitted through the interfaces between the components. The operation of the drive is controlled in dependence on the data exchanged between the components through the interfaces.

By analysis of the course of combustion chamber pressure over the crankshaft angle, characteristic pressure courses are obtained for certain valve control times. From these characteristic pressure courses, a conclusion can be drawn as to the valve control times “outlet opens”, “outlet closes”, “inlet opens”, and “inlet closes”, referred to the crankshaft angle.
