摘要:
A method for controlling the sequence of a plurality of functions which are executable on at least two interacting devices is provided, first of the functions being implemented on a first device and the second of the functions being implemented on a second device. A system for implementing the method is provided, including an administrative unit which controls a sequence of the functions in such a manner that it prevents a first function and a second function which interfere with one another from simultaneously running.

A method for operating an internal combustion engine having at least two exhaust-gas turbochargers, which allows the synchronous operation of the two exhaust-gas turbochargers to be reliably set (adjusted). For each of the at least two exhaust-gas turbochargers, an actuator for controlling the boost pressure produced by the compressors of the at least two exhaust-gas turbochargers is controlled by a separate control signal. At least one of the control signals is corrected in an open-loop-controlled manner for the purpose of synchronizing the at least two exhaust-gas turbochargers.
摘要:
A method for operating an internal combustion engine having an exhaust-gas turbocharger allows for an optimized charge air pressure buildup. For this purpose, an actuator for influencing the charge air pressure generated by a compressor of the exhaust-gas turbocharger is triggered. A characteristic of a trigger signal of the actuator is specified as a function of time.

A method and device for diagnosing a crankcase ventilation of an internal combustion engine, which enable a diagnosis of a malfunction of an actuator of the crankcase ventilation. The internal combustion engine has at least two cylinder banks to which the crankcase ventilation is supplied, and an actuator is provided via whose position the distribution of the crankcase ventilation to the at least two cylinder banks is influenced. In a first position of the actuator, a different distribution of the crankcase ventilation to the at least two cylinder banks comes about than in a second position of the actuator that differs therefrom. Given simultaneously activated operation of the at least two cylinder banks, the actuator is switched over at least one between the two different positions. For at least one of the at least two cylinder banks, a characteristic variable of the internal combustion engine influenced by the crankcase ventilation is determined prior to and following the switchover operation. A minimum value for a change in the characteristic variable of at least one of the at least two cylinder banks and/or the ratio of the characteristic variable between the at least two cylinder banks is specified for the switchover-related change in the distribution of the crankcase ventilation to the at least two cylinder banks. A malfunction of the actuator is detected if at least one change derived from the ascertained values for the characteristic variable undershoots its assigned expected minimum value in quantitative terms.

In a method for detecting combustion misses in cylinders of a combustion engine in part-engine operation in which only some of the cylinders are operated by the injection of fuel, a positional angle of the crankshaft is assigned to an angle segment; each angle segment is assigned to the particular cylinder which predominantly provides the torque for moving the crankshaft through the angle segment; an irregular running datum is determined as a function of a difference of segment pass-through times of immediately successive angle segments; and a combustion miss is detected if the irregular running datum exceeds or undershoots a limit value. In part-engine operation, the irregular running datum is determined only for two successive angle segments that are assigned to a combusting cylinder and to a non-combusting cylinder.

摘要:
A method for switching between operating modes of an internal combustion engine having a plurality of control units, in particular a switchover between full-engine operation and half-engine operation, the control units being able to exchange data via a data link. The method includes a step in which it is checked whether an operating mode switchover should occur and that, if an operating mode switchover should occur, the data link between the control units is tested and/or the operating state of the control units is balanced.
