A method and a device for controlling a drive unit of a vehicle are provided in which, starting from the comparison of a first acceleration variable, which is calculated at least from the operating state of the drive unit, and a second acceleration variable, an error is detected. The second acceleration variable includes a first component, in the direction of the vehicle longitudinal axis, and a second component, perpendicular to the vehicle longitudinal axis.

Method and device for controlling a drive unit of a vehicle

In a method for operating an internal combustion engine, in particular of a motor vehicle, the internal combustion engine is controlled by at least one drive variable, and an instantaneous torque output by the internal combustion engine is determined from a performance variable of the internal combustion engine that differs from the drive variable. To determine the instantaneous torque, an exhaust-gas temperature of the internal combustion engine is used as performance quantity that differs from the drive variable.

Method for operating an internal combustion engine

A method and a device are described for controlling an internal combustion engine. On the basis of the comparison of a setpoint value with an actual value for a variable that characterizes the supplied oxygen quantity, an actuating variable is predefined for controlling an actuating element that influences the fuel quantity conducted to the internal combustion engine and/or the oxygen quantity supplied to the internal combustion engine. The actual value and/or the setpoint value are/is normalized to a reference value.

Method and device for controlling an internal combustion engine

A method and device for controlling an internal combustion engine in which a first variable characterizing the pressure in the combustion chamber of at least one cylinder in the internal combustion engine is detected by at least one sensor. A second variable is determined on the basis of the first variable. Features which are assigned to different partial injections are obtained by forming the difference within the second variable.

A device and a method for controlling an internal combustion engine, where a first variable characterizing the pressure in the combustion chamber of at least one cylinder of the internal combustion engine is measured by at least one sensor. A second variable characterizing the energy released during the combustion is ascertained from the first variable. When a threshold value of the second variable is exceeded, a third variable characterizing the combustion process is detected.

A fuel injection valve for internal combustion engines, having a valve member that is guided so that it can slide axially in a bore of a valve body. The valve member has a valve sealing face on one end which cooperates with a valve seat face on the valve body and this valve member, on an end remote from the valve sealing face, is acted on in the closing direction toward the valve seat by a valve spring, as well as having another adjusting member that controls a two-stage opening stroke course of the valve member. In order to control the two-stage opening stroke course of the valve member, the adjusting member is embodied as an adjustable stop, in which the valve member comes into at least indirect contact with after passing through a partial stroke and which in a first position, is locked in its initial position and in a second position, can be moved in the opening direction by means of the valve member.

Fuel injection valve for internal combustion engines

A method for sensing the temperature of the air supplied to the combustion chambers of an internal combustion engine for the purpose of detecting air mass. Air temperature can be measured using an inexpensive detector having a transfer function exhibiting a delayed response. Dynamic performance is improved by applying to the detected temperature a temperature correction value that is obtained by applying a transfer function that is substantially the inverse of the transfer function of the temperature detector.
