- Intermediate state or the intermediate states independently or executed in the context of an operating mode. So it is on the one hand possible that the intermediate state or the Intermediate states each as independent programs are implemented that are independent of the operating modes and whose programs are available. But it is on the other hand also possible that the intermediate state or the Intermediate states programmatically in the context of one of the Operating modes are available. In the latter case it is for example possible that the intermediate state that is provided for switching to shift operation, as a program within the framework of shift operations Programs exist. So in the latter case it is possible that the intermediate state programmatically the associated operating mode.
- the intermediate states in the intermediate states the measures carried out for switching between the Operating modes are required. It is particularly advantageous it if from the intermediate state or from the Intermediate states the processes for switching are carried out , especially those required for switching Communication.
- This case represents the Transition from a first operating mode to a second Operating mode without a Request to switch to a third operating mode received.
- a further advantageous embodiment of the invention is from an operating mode to an intermediate state and then changed into another intermediate state.
- a request for switching in a third operating mode is transferred, which is the changeover in performs the third mode.
- the invention provides thus the possibility that even during a another switch currently being carried out, different request for a switchover executed can be. This is due to the transition from that current intermediate state to the other intermediate state in a particularly simple, but still extremely flexible Way achieved.
- the operating modes, the intermediate states and the transitions between the operating modes and the intermediate states Automatically executable switchgear.
- This Automatic gearshift controls and controls all transitions between the operating modes of the internal combustion engine.
- the individual operating modes, intermediate states and transitions are preferably implemented as module-like programs, which gives flexibility and at the same time the Clarity increases and the susceptibility to errors is reduced.
- control Program stored on a computing device, in particular on a microprocessor, executable and for Execution of the method according to the invention is suitable.

- the homogeneous shift operation links the properties of shift operation and of homogeneous operation. With the help of homogeneous shift operation For example, a particularly smooth transition from the Shift operation in homogeneous operation and vice versa achieved become.
- a so-called layer heating "skh” of the internal combustion engine 1 also takes place a double injection. It gets fuel from that Injector 9 during the compression phase and during the working phase injected into the combustion chamber 4. To this Way essentially no additional torque achieved but it is achieved through the in the work phase injected fuel quick heating of the Catalyst 12 causes. This is for example with one Cold start of the internal combustion engine 1 is important.
- Internal combustion engine 1 can be switched back and forth or switched become. Such switches are made by the control unit 18 performed. A switchover is triggered by an operating state of the internal combustion engine 1 or through its executive function of the control unit 18. For example, in the case of a cold start, the fifth Operating mode, namely the shift cathe heating triggered with which the catalyst 12 quickly to a Operating temperature is heated.
- FIGS A method is shown in FIGS can be executed by the control unit 18, and that too is suitable between the different modes of operation Switch internal combustion engine 1 back and forth.
- the Indian Block 21 shown in FIG. 2 represents a placeholder represents for the representation of Figure 3.
- the in Figure 3 the circles shown represent the five described Operating modes of the internal combustion engine 1 are shown Ellipses represent so-called intermediate states, and that solid and dashed arrows as well as the Double arrows represent transitions between the operating modes and the intermediate states.
- a target byte 22 is shown in FIG Storage of the operating modes described Internal combustion engine 1 is used in the control unit 18.
- the Set byte 22 has eight bits, three of which are not are busy. At this point it is pointed out that the internal combustion engine 1 described with reference to FIG. 1 and the method described with reference to FIGS. 2 and 3 even with fewer or with more than five different ones Operating modes can be carried out. In this case more or less bits not occupied in the target byte 22.
- the homogeneous operation "hom”, the homogeneous lean operation “hmm”, the shift operation “sch”, the homogeneous shift operation “hos” and the layer-cathe heating "skh” are by one each represents the remaining five bits of the target byte 22.
- the target byte 22 shown in FIG. 2 is for this provided, the target mode, that is, the desired To mark the operating mode of the internal combustion engine 1.
- the target mode that is, the desired To mark the operating mode of the internal combustion engine 1.
- the actual operating mode can be set in a target byte 22 corresponding actual byte is stored in the control unit 18 be, as indicated in Figure 2. In this the latter actual byte is then only set to that bit which represents the operating mode in which the Internal combustion engine 1 is currently located.
- target byte 22 for the target operating mode and the corresponding actual byte for the actual operating mode are each a binary data word, with each of the Operating modes by a certain bit in the same place of the respective binary data word is represented. It it should be noted that the target byte 22 and the actual byte differentiate from each other as described and accordingly must be kept apart.
- the internal combustion engine 1 In shift operation, the internal combustion engine 1 is switched on predefined manner controlled and / or regulated. in the The internal combustion engine 1 operates homogeneously on one of them different ways controlled and / or regulated.
- the throttle valve 11 is in shift operation usually wide open, while in homogeneous operation resulting torque by throttling the air supply is influenced by the throttle valve 11.
- the exhaust gas recirculation valve 14 in shift operation usually opened further than in homogeneous operation and the tank vent valve 17 is also mentioned in the Operating modes controlled differently.
- This intermediate state can be an independent one Program that is intended only for the Realize intermediate state. It is also possible that the intermediate state is programmatically an operating mode assigned. So it is possible that the intermediate state a program as part of the actual operating mode or target operating mode represents.
- this includes the processes for the Switching from the actual operating mode to the target operating mode.
- the intermediate state is therefore for the Switchover responsible. In particular, from that Intermediate state all that communication with external Functions and the like performed for the Switching is required.
- the Figure 2 In the intermediate state "zhom" according to block 21 the Figure 2 generates requests, for example Control functions such as exhaust gas recirculation and / or Be vented. As more options can meet the requirements for control functions for fast Torque interventions and / or for filling interventions and / or the like are passed on. With the broadcast The control functions mentioned are requirements indicated that a desired target mode is requested.
- Control functions such as exhaust gas recirculation and / or Be vented.
- the actuating functions then check the target byte 22 um derive the desired target operating mode from this. Then the control functions are set to the desired target operating mode on. As soon as one of the control functions this Has carried out the setting, sends it according to FIG. 2 a receipt to the intermediate state "zhom".
- the exhaust gas recirculation from an open Condition converted into a rather closed state. As soon as this state is reached, the Exhaust gas recirculation sends a receipt to the intermediate status "zhom". The same applies to tank ventilation or the Move the position of the throttle valve 11.
- Desired target operating mode is read out of target byte 22. Then the respective control function is set to this target operating mode set. As soon as the respective actuating function is set to the desired target operating mode the associated receipt is generated.
- the requirements can vary from the intermediate state "zhom” possibly only to certain of the existing ones Control functions are given. Also from that Intermediate state “zhom” possibly only certain of the incoming receipts are used. The requirements can thus from the intermediate state “zhom” to all or are only given to individual control functions. Accordingly, all or only individual receipts from the intermediate state "zhom” can be used.
- the requirements can vary from the intermediate state "zhom” in a chronological sequence to the different Control functions are given. So it is possible that the requirement for a specific actuating function is given when another's receipt Actuating function has been received.
- the requirements can thus from the intermediate state "zhom” in terms of time are delivered in parallel and / or in series.
- a transition to the "hom” mode is involved to the associated one already mentioned in the example above Intermediate state “zhom”. With a transition to the Operating mode “hmm” is the associated one Intermediate state “zhmm”. With a transition to the Operating mode “hos” is the associated one Intermediate state “zhos” and with a transition to Operating mode “sch” is the associated one Intermediate state “zsch”.
- FIG. 3 shows each of the four Intermediate states a double arrow to the corresponding one Operating mode shown. For example, from that Intermediate state "zhom” a double arrow to the associated Operating mode “hom” shown.
- the described transition from one of the operating modes in another of the operating modes via one of the Intermediate states require a certain period of time. During this period there is a possibility that changes the desired target operating mode. So it is possible that a target operating mode is specified that however, before a transition to this target operating mode another target operating mode is desired.
- first target operating mode a transition in accordance with FIG result in a first intermediate state.
- first Intermediate states are those for the first target operating mode necessary measures carried out. Now go during the Implementation of these measures the requirement of a other, second target operating mode, so you can measures required for this second target operating mode cannot be performed from the first intermediate state.
- This transition from a first intermediate state to one second intermediate state may change due to corresponding third and further requirements each Repeat different target operating modes. There is none Request to switch to another target operating mode before, so from the last intermediate state performed changed to the last desired operating mode.
- the operating mode layer heating "skh”, which is shown in FIG marked by circle 28 is an exception To this mode of operation "skh” can be used without the Interposition of an intermediate state directly from the Shift operation "sch” to be transferred. Accordingly can from the layer heating "skh" directly into the Shift operation "sch" can be switched.
- the operating modes "hom”, “hmm”, “hos”, “sch” and “skh”, the Intermediate states “zhom”, “zhmm”, “zhos” and “zsch” and the Transitions between these modes and Intermediate states according to FIG. 3 form one so-called automatic switch, which by the control unit 18th executed and thus realized.
- the automatic switch controls and monitors the sequence when switching between the operating modes.
- the automatic switch of Figure 3 is more or less operating modes or intermediate states can be expanded or reduced.
