- the cold start and the warm start are in the controller 15 as an algorithm deposited as a function of corresponding sensor signals.
- the cold start can be defined be that the engine oil temperature and the outside temperature below a predetermined value is and / or that the shutdown time since the last operation of the internal combustion engine greater than one is predeterminable time interval. Accordingly reversed is the Warm start defined, thus at engine oil temperatures and outside temperatures above definable values and / or during shutdown times is less than a predetermined time interval.
- These sensor sizes can also interact in a specific way stand.
- For the cold start can have two different starting procedures be realized, wherein at a startup of the motor-operated generator parallel to the starter 11 works. The starter is then deactivated at a certain speed, and the motor-driven generator accelerates the crankshaft continues to the starting speed.
- the starter 11 is first turned on and only after reaching a certain speed this is deactivated and the motor-operated generator activated.
- a speed value for example, 80% of the starting speed corresponds, no injection and no ignition, so that the internal combustion engine 10th is started at this time, which then very fast he follows.
- This is done by means of an electronic, not shown Motor control, which is in operative connection with the electronic Control device 15 can stand. This delayed Insertion of ignition and injection takes place accordingly even at a boot process alone by the generator 12th
- Usual starters 11 have a total translation of approx. 60: 1, resulting from the translation of starter pinion to the crankshaft and from the submission translation.
- inventive Arrangement can significantly reduce this translation be, for example, the counterclaim can be omitted, so that results in a total translation of 15: 1.
- the electronic control device 15 even while the internal combustion engine 10 the Control generator 12, for example, for driving dynamics support.
- the motor-driven generator 12th support these acceleration processes.
- deceleration processes in generator mode that is, in overrun mode and braking mode, it becomes regenerative operated so that not only dependent on the driving situation electrical energy is recovered, but also the deceleration process is actively supported.
- the electronic control device 15 switching operations at gear changes of the transmission of the internal combustion engine 10 actively assist and synchronize engine and Transmission speeds are used. To increase the speed is while the motor-operated generator 12 and speed reduction the generator-operated generator 12 is used become. This leads to faster gear changes, causing less Even a clutch can be omitted.
- the electronic control device 15 for preventing a belt slippage of the drive belt for the generator 12 serve.
- a measuring device, not shown for Recognition of the belt slip gives its measuring signals to the electronic Control device 15 further, by means of the active Generator 12 the belt slip causing additional moments on the belt drive belt-friendly on and disengages or compensated.
- This measuring device for detecting the belt slippage can also be part of the electronic control device 15 be where speeds of generator 12 and internal combustion engine 10 compared with each other.
- For belt slip detection can, for example, at the leading strand and return strand of the Drive belt depending a measuring roller to be articulated resiliently, the the taking place due to different moments stretching the Capture drive belt.
- the detection of belt slippage allows a preventive belt diagnosis, and a looming belt problem can be communicated to the driver of a motor vehicle early be, for example, by a visual and / or acoustic Warning device or a display.
- the electronic control device 15 can also be used for positioning the crankshaft are used.
- the internal combustion engine is the crankshaft by the motor operated generator 12 a favorable well-defined starting position impressed.
- the generator is for this purpose, for example as fully developed four-quadrant positioning drive.
- the next startup process of the internal combustion engine can thereby take place from a defined initial position, whereby the Startup process is significantly accelerated.
- the arrangement according to the invention is also suitable for control or influencing the outlet of the internal combustion engine 10. It poses a problem that often undefined amounts of fuel after stopping the engine 10 in the intake system and remain in the cylinders. The volatile parts of the fuel evaporate, while this is difficult flammable fractions is not the case. They deteriorate the exhaust when re-starting the engine. this will avoided in one embodiment of the invention in that at Turn off the engine 10, the fuel supply or Fuel injection is switched off. The internal combustion engine 10 is then by the generator 12 in the engine operation held in rotation for a certain time, causing the internal combustion engine rinsed and fuel residues, which are also in the catalyst can be disposed of harmlessly. At a restart the engine, the engine control unit or the control device 15 of an "empty" internal combustion engine go out, which facilitates a defined start.
- the Internal combustion engine 10 defined by means of the generator 12 at regenerative braking to a standstill, because a long follow-up phase is undesirable.
- Another application of the drive arrangement according to the invention is to start-stop operations of the internal combustion engine 10, for example, to improve traffic lights.
- the chances for a Realization improve especially when the start of the Internal combustion engine or the motor vehicle in each case without delay he follows. Even the slightest delay is on above all subjectively extremely disturbing noticeable.
- the electronic control device 15 is in communication possible with the generator 12, without disengagement of the internal combustion engine to stop the vehicle. Possibly otherwise available Torque shocks can be compensated comfortably by the generator become.
- the start is then again without Actuation of a clutch by "electric" start, what entirely without delay is possible. This can of course even when disengaged internal combustion engine done.
- the purely electric starting takes place in motor operation the generator 12 in eventual support by the Starter 11, especially in cold engine or very low temperatures.
- the coupling or starting the Internal combustion engine 10 can then be delayed in time, in particular also pulse-shaped. Since when starting the Internal combustion engine then the vehicle is already in motion, will be the kinetic energy of the entire vehicle and not only individual drive train parts for starting the internal combustion engine co-used, so that a safe start is guaranteed.
- Such a start-stop system preferably works in conjunction with a road condition detection system, such as an electronic Stabilization system or traction control system.
