- a speed n, nl, n2, n3 of the drive shaft 222 is detected, this detected speed n, nl, n2, n3 is compared with a predetermined speed value nG and in the case that the speed n, nl, n2, n3 is less than or equal to or less than or equal to or not greater than the predetermined speed value nG, the starter pinion 22 is vorgespurt toward the ring gear 25.
- N indicates the rotational speed of the drive shaft 222 in general.
- FIG. 4 shows a similar diagram as in FIG.
- the outlet 261 shown there is somewhat different from that shown in FIG.
- the speed level of this curve is slightly lower, which can be detected, for example, at the position of top dead center OT2.
- This top dead center OT2 is slightly below the Target speed nZ.
- the angle a S tart2 is located exactly at a position of the bottom dead center UT3.
- the sequence according to this outlet 261 is the same as that according to FIG. 3.
- the rotational speed of the drive shaft 222 determined in the angular position astarti at UT2 is greater than the predetermined rotational speed value nG.
- the rotational speed value n3 is smaller than the predetermined rotational speed value nG, so that in this case the starter pinion 22 is pre-spun in the direction of the toothed rim 25. This toe-in again takes place during the time interval ⁇ t, so that even in this case the starting pinion 22 meshes with the desired speed nZ in the sprocket.
- a target rotational speed nZ is a rotational speed of the drive shaft 222, to which the starter pinion 22 intentionally lashes in, with a drive time
- Time difference between an application time tZ and the start time is.
- the outlet 261 is even lower, i. H.
- z. B the time period At significantly larger than in the other embodiments. In this case, this means that the time required for the starting pinion 22 to at least advance to the ring gear 25 is significantly greater, in this case approximately three times as long as in the case of the others
- Embodiments is. The differences are even bigger here:
- the angle a at which the rotational speed n of the drive shaft 222 is determined is approximately midway between a bottom dead center UT and a top dead center OT (approximately the turning point of the spout 261) and on the other hand, a starting time tstart deviates from the time at which the drive shaft 222 the Angular position a S tart2 occupies.
- a rotational speed n or nl is previously determined at the angular position astarti and in this case, as in the other embodiments, it is found that this rotational speed value is too large compared to the rotational speed nG.
- a speed n2 is determined, which is smaller than the predetermined speed value nG.
- the starting pinion 22 is pretensioned in the direction of the toothed rim 25 in accordance with the proposed method.
- the actual active toggle process begins only at a time tstart, which is after the time when taking the drive shaft 222 of the
- Angular position a S tart2 is present. This is because it is provided in the context of the method to apply the starting pinion 22 preferably to the target rotational speed nZ to the ring gear 25 and preferably then stabilitspuren in the ring gear 25.
- the point in time at which the decisive rotational speed nStart is determined and the time tStart at which the starting pinion 22 starts to track are not identical.
- crankshaft angle or drive shaft angle a S tart to which the Einspurvorgang should begin for example, be set via a so-called map.
- Angular position a S tart2 has been entered, depending on the actual speed value at this moment be set at this angular position a S tart2 that the starting operation should begin when the angle a S tart.
- the time after another start of Atstart start the process instead of the time from the time at which the drive shaft 222 meets the condition, the time after another start of Atstart start the process instead.
- the starting process or the toggle operation are initiated after the drive shaft 222 has reached a speed n S tart.
- Internal combustion engine 210 is not tolerable by the speed nZ. This is especially true for a return swing of the drive shaft 222.
- FIG. 7 shows three different outlets 261. These three spouts have different speed levels.
- the outlet 261 with the highest speed level deviates from the next lower outlet 261 shown here, at least in the position OT2 with a speed difference of ⁇ .
- This ultimately average speed output 261 deviates from the outlet 261 with the lowest speed level with the speed difference ⁇ 2.
- the topmost path 261 has the highest
- Speed level at a S tart23 the speed of the drive shaft 222 an amount which is indeed between the speed nZ and nG, but this speed is also much greater than nZ.
- Andrehritzel 22 rests on the ring gear 25 may be greater than the speed nZ, but it may also be less than the speed nZ.
- the Einspurdusiere the drive shaft 222 nZ may even be negative compared to the usual direction of rotation of the drive shaft 222 (drive case).
- the drive shaft 222 comes at a point PO for a moment to a halt, then swing back (rotational oscillation of the drive shaft 222). In any case, the drive shaft 222 would have such a movement behavior at least if the starter pinion 22 did not engage in the toothed rim 25 or would abut against the toothed rim 25.
- the range of values of ⁇ is here for example limited to the distance between two adjacent dead centers, this distance between two adjacent top dead centers being limited to the value range between 0 degrees and the quotients of 720 degrees and the number i of the cylinders of the internal combustion engine 210. In the example, that means at one
- Internal combustion engine 210 with in-line six-cylinder engine the range of values is thus limited to a range between 0 degrees and 120 degrees.
- the engine speed 210 is nOTF, a top dead center OT2 ⁇ nG, i. at most as large as a previously determined limit speed nG, the internal combustion engine 210 is under its given operating parameters with its inertia energetically unable to another top dead center OT in the forward movement (i.e.
- the inertia or the moment of inertia J takes into account, for example, the inertia of the drive shaft 222, the inertia of the connecting rod 231, the inertia of the piston 237 and of course the inertia of the ring gear 25 u. a. Parts such as camshafts, valves, coupled belt drives and driven thereby rotating masses such. B. a generator.
- the limit speed nG is assumed to be constant at constant engine operating conditions 210 for various engine outlets 261.
- the limit speed nG can be stored in a memory table for the different parameters, If, for individual parameters, no exact value is available, corresponding intermediate values can be set by means of customary
- Drive shaft 222 passes through to decide whether the state of motion of the drive shaft 222 meets the criterion that the rotational speed n in the assumption of the angle satisfies the condition n ⁇ nG. As in the previous embodiment, then the starter pinion 222 after reaching the
- the angle is in the region of the inflection point between the bottom dead center UT2 and the top dead center OT2.
- the starter pinion 22 is pre-loaded, in order then to abut at the time tE on the ring gear 25 or in this
- the limit speed nG itself can be determined by a suitable method. As already mentioned, this can be stored, for example, in a characteristic field as a function of the operating parameters occurring-to which reference has already been made. The speed nG can be determined during the engine rundown 261, for example via an energy consideration. Furthermore, the speed nG can also be determined by means of a learning function taking into account already recorded engine outlets.
- FIG. 11 again shows three outlets 261.
- the high-speed spout 261 has a speed n at top dead center OT2, which is equal to the speed nG.
- the starter pinion 22 is only relatively late in the direction of the ring gear 25 when it reaches the angle a S tart. In all three
- Drive shaft position is in which a piston 237 is in the position OT2.
- the starting angle a start is still closer to the position OT2.
- a S tart (astart2i, astart22, astart23) would then the starting device or a Vorspuraktuator so driven to constructivespuren at a target speed nZ to a different time tE.
- the time tE for each run-out curve 261 is a different time.
- the target rotational speed nE would not be a fixed target rotational speed nZ but a target rotational speed nZ, which in this example fluctuated around an average value with a rotational speed difference An.
- the fluctuation range would then correspond to approximately half of the limit speed nG.
- Starter motor or the Andrehritzels 22 the starting angle a S tart due to the speed of one or more characteristic points z.
- B the speed of the last top dead center nOT2 be adjusted.
- a possible method of adaptation here is the storage of a map for different speeds in that top dead center OT or the recalculation of a S tart via a learning function.
- Target speed nZ result A change in the characteristic of the spout 261 can therefore be divided into two types:
- the average engine outlet gradient can, for. B. by a change in friction, the effective in the engine outlet loads, the temperature of other parameters can be varied. Due to the variation, the limit speed nG and / or the starting angle a s tart should be adjusted if necessary. The spread of this
- Parameter can be determined by vehicle measurements at different
- Border situations are analyzed by motor simulations.
- the specified motor type can be influenced by operating conditions, series dispersion and aging effects.
- FIG. 1 For the sake of clarity, a schematic representation of FIG. 1
- the control unit 255 is connected to the internal combustion engine 210 by means of a connection device 309 (eg cable) which, for example, enables the transmission of signals from the rotational speed sensor 300 to the control unit 255.
- a connection device 312 is used to control the Vorspuraktuators 16, after which a suitable start time tStart is determined.
- Embodiments characterized by a very dynamic course. Macroscopically, the speed drops. However, this course is characterized by relative minima in the range of top dead centers and relative maxima in the area of bottom dead centers. Furthermore, the course thus has positive (between upper and lower dead centers) and negative (between lower and upper dead centers) slope values.
- the program instructions 306 can be loaded, for example, into the program memory 303 via an interface (eg plug connection).
- FIG. 12 shows a control unit 255 for a start-stop operation of a
- Internal combustion engine 210 in a motor vehicle 310 for short-term stopping and Starting the internal combustion engine 210 wherein the internal combustion engine 210 can be started by means of an electric starting device 10, wherein the control device 255 has a processor 313 with a program memory 303.
- the processor 313 is designed as a detection, evaluation and control device to control the starting device 10 defined, wherein in the program memory 303 a aforementioned computer program product is loaded to perform a method according to one of the steps described above.
- the start-stop mode allows an automated
