Problems solved by technology

A disadvantage of the above-mentioned known systems is that in the event of a failure of the control unit, the remaining, still functioning control unit alone cannot ensure the continued operation of the internal combustion engine
As a rule, the entire control unit combination is completely shut down when only one control unit fails, so that the internal combustion engine cannot continue to run

Embodiment Construction

[0023] figure 1 A diagram of an internal combustion engine 200 is shown, which is equipped with a total of two control units 100 , 100 a for controlling the internal combustion engine 200 . Internal combustion engine 200 is, for example, a diesel engine with two block bases each having 6 cylinders (not shown).

[0024] The internal combustion engine 200 is controlled via two control devices 100 , 100 a. In this case, the control units 100 , 100 a work in a combination of control units according to the master-slave principle in such a way that the other control unit 100 a assumes the master function and the control unit 100 assumes the slave function.

[0025] Control unit 100 can be configured, for example, to control a first cylinder base of internal combustion engine 200 . In contrast to this, further control unit 100 a can be provided, for example, to control at least one other cylinder base of internal combustion engine 200 . Since the control unit 200 is designed here ...

Abstract

A method for operating a control unit (100) for an internal combustion engine (200) is described, the control unit together with at least one additional control unit (100a) actuating the internal combustion engine (200) in a first operating mode, wherein the control unit (100) monitors (300) the at least one additional control unit (100a) for a malfunction and / or failure, and in the event of a malfunction and / or failure of the at least one additional control unit (100a), the control unit (100) switches (310) from the first operating mode to a second operating mode, in which the control unit (100) is able to maintain an operation of the internal combustion engine (200) independently of the at least one additional control unit (100a).

Description

technical field [0001] The invention relates to a method for operating a control unit for an internal combustion engine, wherein the control unit jointly controls the internal combustion engine together with at least one further control unit in a first operating mode. [0002] The invention also relates to a control device for an internal combustion engine according to the preamble of claim 9 . Background technique [0003] Such methods and devices are known and are used, for example, to control marine engines or large stationary engines. A disadvantage of the known systems described above is that, in the event of a control unit failure, the remaining, still functioning control unit alone cannot ensure continued operation of the internal combustion engine. As a result, the entire control unit combination is usually completely shut down when a single control unit fails, so that the internal combustion engine cannot continue to run. Contents of the invention [0004] Accor...
