摘要:
An internal combustion engine, especially for a motor vehicle, is described which is provided with a control apparatus. A number of functions can be executed at time intervals and/or in dependence upon the rpm of the engine. Furthermore, a quantity (RA), which defines the utilization of the control apparatus, and a quantity (N), which defines the rpm of the engine, can be determined. The number of executed functions can be reduced by the control apparatus when the quantity (RA), which defines the utilization, is greater than a utilization threshold value (ASW1).

The invention is directed to a method and an arrangement for equalizing torque contributions of different cylinders of an internal combustion engine to the total torque of the engine. The engine can operate in an overrun mode and in a fired mode. First quantities (Ka) are provided of a rough running of the engine in the overrun mode and second quantities (Kvi) are provided in the fired mode. Third quantities (Ksi) for a rough-running component based on torsion vibrations are also provided. Cylinder-individual fourth quantities (Kki) for the rough running are formed from the first, second and third quantities with the fourth quantities being independent of the rough running in the overrun mode and independent of the rough-running component based on the torsion vibrations. The torque contributions are equalized on the basis of the fourth quantity.

The invention proceeds from a vehicle having a clutch and a transmission. The clutch is mounted in the drive train of the motor vehicle and the transmission is mounted in the drive train and is changeable with respect to its transmission ratio. Furthermore, means are provided which generate a clutch signal which represents the actuation of the clutch. The essence of the invention is that a change of the transmission ratio is detected. According to the invention, monitoring means are provided by means of which a fault signal is generated in dependence upon the recognized change and the generated clutch signal. The fault signal indicates whether the means, which generates the clutch signal, operates properly. A further variation of the invention evaluates the clutch actuation with the first start of movement of the vehicle after the engine start.
