Definitions
- the powertrain includes an internal combustion engine associated with an electric machine that generates torque when the internal combustion engine is started. Between the internal combustion engine and a transmission, a clutch is provided, via which a torque generated by the internal combustion engine is transmitted to at least one vehicle drive wheel. Means are provided which actuate the clutch at the start of the internal combustion engine in such a way that a first part of the torque generated by the electric machine when the internal combustion engine is started is transmitted to the at least one vehicle drive wheel and a second part of the electric motor sufficient to start the internal combustion engine Machine generated torque is transmitted to the internal combustion engine.
- the clutch is operated by means of a control device taking into account temperature and / or speed-dependent maps for the drive torque of the internal combustion engine and / or for the starting torque and / or for the clutch engagement mainly dependent on the clutch engagement.
- the motor vehicle can be moved depending on the design of the drive train only with the help of at least one electric drive.
- the at least one electric drive supplies the entire drive energy, whereas the internal combustion engine remains switched off.
- the stationary internal combustion engine can be started by the at least one electric drive, for example by means of the pulse start, wherein the angular momentum of the at least one electric drive in rotation is used to drive the stationary internal combustion engine
- the speed of the at least one electric drive is first increased an electric drive and a vehicle transmission arranged clutch operated torque-controlled and transmits in this phase of the motor vehicle equipped with a hybrid drive the driver's desired torque.
- a clutch located between the at least one electric drive and the internal combustion engine is closed.
- a disadvantage of this approach is the fact that the clutch operated in the slip state between the vehicle transmission and the at least one electric drive can not be permanently operated in this slip condition, which is required on the one hand to maintain a continuous output number, but on the other hand to a mechanical or thermal see Overloading this clutch would result. This precludes permanent operation of this clutch between the at least one electric drive and the transmission of the vehicle equipped with a hybrid drive.
- the present invention has for its object to avoid a fall in speed of the drive at the start of the internal combustion engine within a drive train of a vehicle equipped with a hybrid drive vehicle.
- This object is achieved in that at a speed drop of the at least one electric drive at a pulse start in the internal combustion engine of the hybrid drive, a gear shift operation takes place, which compensates the speed drop of the at least one electric drive at the pulse start of the internal combustion engine.
- the speed drop of the at least one electric drive occurring when starting the internal combustion engine is compensated by a continuously changing transmission ratio of the transmission, so that the output speed of the at least one electric drive can be kept constant and thus the propulsion of the motor vehicle with hybrid drive can be kept constant.
- Gearboxes with which a continuous change of the transmission ratio can take place, for example, automatic transmission or belt transmission.
- the proposed solution according to the invention can be achieved in an advantageous manner that the speed of the at least one electric drive can be increased permanently, so as to start immediately when needed, the internal combustion engine of the hybrid drive. Furthermore, by the proposed solution according to the invention a waiver of the clutch, which is usually provided in hybrid drives between the vehicle transmission and the at least one electric drive, can be achieved. This eliminates the need to operate this clutch torque controlled. Finally, it can be achieved by the inventively proposed solution that the previously required time to increase the speed of the at least one electric drive of the hybrid drive can be omitted, since the at least one electric drive can be operated permanently at a higher speed.
- the vehicle transmission which preferably as an automatic transmission or z. B.
- the speed drop of the at least one electric drive which is caused by the spinning of the crankshaft of the internal combustion engine, compensated by means of a continuous changing the Ü-gear ratio in the vehicle transmission.
- the vehicle transmission switches at the pulse start of the internal combustion engine of the hybrid drive continuously from a first gear ratio to a second ratio such as from a second gear to a first gear in the case of an automatic transmission, the second gear ratio is higher than the first gear ratio, since the input speed of the vehicle transmission due to the speed drop of the at least one electric drive at pulse start drops.
- the transmission ratio i is given by ( ⁇ Ant ⁇ eb / ⁇ output- If the output speed ⁇ A bt ⁇ eb remains constant and decreases the drive speed (öAnt ⁇ eb, applied by the at least one electric drive due to the pulse start of the internal combustion engine, so the transmission ratio i decreases.
- FIG. 1 shows the components of a hybrid drive of a vehicle with a coupling between the at least one electric drive and the internal combustion engine and a further coupling between the at least one electric drive and the vehicle transmission
- FIG. 2 shows a speed diagram of the rotational speeds of the at least one electric drive and the internal combustion engine to be started during the starting phase, plotted over time
- Figure 4 shows the speed diagram of the at least one electric drive at the desired higher speed of the electric drive
- Figure 5 is a taking place within the vehicle transmission gear ratio change.
- FIG. 1 shows the components of a hybrid drive with an internal combustion engine, at least one electric drive, a clutch arranged between them and with a further clutch between the at least one electric drive and a vehicle transmission.
- a drive train 10 of a motor vehicle equipped with a hybrid drive 12 comprises an internal combustion engine 14.
- the internal combustion engine 14 can be coupled by means of a first clutch 16 to at least one electric drive 20, which represents a further component of the hybrid drive 12 shown in FIG.
- An output shaft 22 of the at least one electric drive 20 can be coupled via a further, second clutch 24 to a vehicle transmission 26.
- the internal combustion engine 14 can be started out of the operating mode "electric driving.” This is generally done by means of a pulse start to set in rotation and to start. For this purpose, however, the increase in the rotational speed of the at least one electric drive 20 is required.
- the further, second clutch 24 is operated in the configuration shown in FIG. 1 in the slip state.
- a disadvantage of this starting process in the context of a pulse start of the internal combustion engine 14 is the fact that the further, second clutch 24 can not be operated permanently in the slip state, since this would otherwise be mechanically or thermally overloaded.
- FIGS. 2 and 3 show rotational speed and torque diagrams, wherein the rotational speed or the torque of the at least one electric drive are respectively plotted over the time axis.
- the at least one electric drive 20 is operated at an output speed ⁇ > o.
- an increase in torque of the at least one electric drive 20 operated in the "electric driving" operating state is desired according to the driver's request 38, compare the driver's desired torque 38 in FIG. 3.
- the rotational speed of the at least an electrical drive 20 as shown in Figure 2 continuously increased until the at least one electric drive 20 has assumed an increased speed ⁇ > i.
- the internal combustion engine is running at its rotational speed ⁇ 2.
- the configuration of the hybrid drive 12 shown in FIG. 1 requires that the further, second clutch 24 be operated in the slip state, furthermore the pulse starting operation of the internal combustion engine 14 to be started lasts longer, since first the at least one electric drive 20 has to be accelerated from its output rotational speed ⁇ > o to the increased rotational speed ⁇ > i and only then can a coupling process take place.
- a complex control of this further, second clutch 24 is required as a torque-controlled clutch.
- FIG. 4 shows the configuration of the drive train proposed according to the invention.
- the further, second clutch 24 is dispensed with.
- the internal combustion engine 14 of the drive train 10 shown in FIG. 4 is connected via its output shaft 18 to the still existing first clutch 16, which in turn is coupled to the at least one electric drive 20.
- the output shaft 22 of the at least one electric drive 20 is connected to the vehicle transmission 26.
- FIGS. 5 and 6 show the speed diagram of the at least one electric drive and at least one drive wheel over time and the course of the gear ratio plotted over time during a pulse start.
- FIGS. 5 and 6 relate to the drive train 10 illustrated in FIG.
- the rotational speed of the at least one electric drive 20 increases from ⁇ > o to ⁇ > i.
- the change of the transmission ratio in the transmission ratio of the vehicle transmission 26 from the gear ratio ⁇ l to the gear ratio ii it is downshifted, for example, from a second gear in a first gear.
- the at least one electric drive 20 see from the outset with increased Speed ⁇ > i are operated.
- the vehicle transmission 26 is operated with the transmission ratio ii.
- the vehicle transmission 26 is preferably designed as an automatically shifting transmission or designed as a belt transmission (CVT transmission). This ensures that during the pulse start of the internal combustion engine 14, the propulsion of the vehicle is continuously maintained.
- the variant of the drive train 10 proposed according to the invention also makes it possible to operate the at least one electric drive 20 at an increased rotational speed ⁇ > i, so that the "pulling-up phase" of the at least one electric drive 20 required within the time span 46 can be dispensed with.
- the solution proposed according to the invention eliminates the second additional coupling 24 required in FIG. 1 and its time-consuming torque control.
- it is possible to achieve "winding" of the at least one electric drive 20, ie to increase its rotational speed, whereby the transmission ratio in the vehicle transmission 26 is continuously increased, which is brought about by a downshift Pulse start of the internal combustion engine 14, which is connected to a speed decrease at least one electric drive 20, the output speed ⁇ A bt ⁇ eb the vehicle transmission 26 are kept constant, since the gear ratio i (öAbt ⁇ eb / ⁇ drive drops, thus an upshift within the vehicle transmission 26 takes place.
