Problems solved by technology

Likewise, in the operation of self-ignition internal combustion engines, higher particulate and nitrogen oxide emissions have to be taken into consideration at high torques, in contrast to the danger of catalytic converter cooling at low torques of self-ignition internal combustion engines

Embodiment Construction

[0020] The main components of a hybrid drive, in particular a parallel hybrid drive of a vehicle, can be seen from the schematic diagram according to FIG. 1 .

[0021] Hybrid coordination device 10 is connected not only to control unit 12 for internal combustion engine 18 but also to control unit 14 for at least one electric drive 20 and also to control unit 16 for vehicle transmission 24 . In the drawing shown in FIG. 1 , the internal combustion engine 18 is rigidly coupled to the at least one electric drive 20 . Between at least one electric drive 20 and a vehicle transmission 24 there is a clutch 22 , which is only shown schematically here. A clutch can also be arranged between the internal combustion engine 18 and the at least one electric drive 20 . A drive shaft 26 extends from the output of the vehicle transmission 24 , which transitions into the drive train of a vehicle with a hybrid drive, not shown in any further detail here. A transmission output torque M_out and ...

Abstract

The invention relates to a method for adjusting the operating conditions of an internal combustion engine (18), particularly an internal combustion engine (18) of a hybrid drive. In addition to the internal combustion engine (18), the hybrid drive comprises at least one electric drive (20), a hybrid co-ordinator (10) and a control unit (12, 30), which is allocated to the internal combustion engine (18) and in which functions (38, 40, 42) are implemented. The functions (38, 40, 42) request the provision of operating conditions (58) that benefit their running ability for the internal combustion engine (18) from the hybrid co-oordinator (10), which makes a corresponding modification to the distribution of power between the internal combustion engine (18) and the electric drive(s) (20).

Description

Background technique [0001] The various functions involved in the control of the internal combustion engine, such as diagnostics or adaptation, require defined operating states of the internal combustion engine, such as idling or specific load / speed characteristics, for example, in order to be able to function completely. If this operating state does not occur during the drive cycle, the function will not operate. [0002] From the document DE 10 2004 0445 501.9 with the filing date of September 15, 2004, a method for operating a vehicle drive and a tool for carrying out the method are known. A method for operating a vehicle drive is disclosed, wherein the vehicle drive has at least one internal combustion engine and at least one electric machine mechanically coupled to the at least one internal combustion engine, and the electric machine and / or the internal combustion engine Functionally connected accumulator. The at least one internal combustion engine and the at least one...
