Definitions
- the present invention relates to a method for operating a hybrid vehicle having a supercharged internal combustion engine with overboost function and at least one electric drive, wherein after an overboost phase of the supercharger of the internal combustion engine follows a regeneration phase thereof with a corresponding torque drop.
- the invention further relates to a hybrid vehicle with a supercharged internal combustion engine with overboost function, a supercharger for the internal combustion engine, at least one
- overboost In vehicles with supercharged internal combustion engines, it is possible to increase the available maximum torque over a short period of time by an overboost function. Such an increase in torque can be achieved in certain driving situations, for example at full load or kickdown.
- Overboost refers to a function that allows the maximum engine torque to be increased for a short period of time when accelerating sharply, temporarily increasing the boost pressure above the normal value.
- Hybrid vehicles are known. They point beside one
- the present invention has for its object to provide a method of the type described above, with which a particularly good handling of the hybrid vehicle can be achieved.
- This object is achieved in a method of the specified type in that the at least one electric drive is used to the torque drop of
- the method according to the invention it is thus possible to extend the overboost phase of the supercharger of the internal combustion engine while the maximum torque is being made available, since during the subsequent regeneration phase a torque drop of the internal combustion engine occurs, but this occurs due to the at least one of the at least one Electric drive supplied torque is at least partially compensated.
- the supercharger of the internal combustion engine can therefore continue to undergo a regeneration phase as in the prior art in order to protect it from overheating. Nevertheless, during the
- the overboost regeneration phase therefore, there is an addition of the reduced torque delivered by the internal combustion engine and the torque supplied by the electric drive, so that overall a high or the maximum torque from the overboost phase is still provided.
- the overboost phase is therefore extended without damaging the charger in any way.
- the overboost phase and the regeneration phase of the supercharger of the internal combustion engine are therefore inventively preferably combined with each other without torque drop, so that there is an improved handling with the support of the electric drive.
- the entire overboost phase is lengthened by the method according to the invention, and a constant torque can preferably be provided during this entire overboost phase, which leads to a constant acceleration or vehicle speed.
- a constant torque is provided over the extended overboost phase.
- the torque drop compensation is expediently carried out over a defined number of operating phases. This number of operating phases can be optimized with respect to the available battery load of the vehicle. The driver of the hybrid vehicle is therefore a prolonged Overboost function over a certain number of operating phases available, depending on the state of the electric drive, ie battery condition, battery load, etc. The end of an overboost phase can hereby be used to recharge the battery of the vehicle.
- the torque achieved thereby is increased by the static torque of the electric drive during the overboost phase of the supercharger.
- the compensation phase is preferably carried out so that the torque during the regeneration phase is maintained at the torque value increased by the static torque of the electric drive during the overboost phase. This can also during the
- Overboost mode can be operated so that in this way the maximum torque of both types of drive can be exploited.
- the overboost function itself can follow the maximum torque provided by both types of drive, but may also be designed for alternating overboost and charge cycles.
- the present invention further relates to a hybrid vehicle with a supercharged internal combustion engine with overboost function, a supercharger for the internal combustion engine, at least one electric drive and a control unit.
- This hybrid vehicle according to the invention is characterized in that it has a device which detects the end of the overboost phase of the supercharger and informs the control unit about this end, and that the control unit is designed so that it controls the electric drive in dependence thereon this provides the required torque to compensate for the torque drop in the overboost phase following regeneration phase of the supercharger.
- the electric drive After detecting the end of the overboost phase of the charger, therefore, the electric drive is switched on or put into operation to provide additional torque available and in this way to compensate for the torque drop of the internal combustion engine, at least partially.
- the control unit is designed so that it controls the electric drive so that it provides additional torque, so that the overall constant torque value results during the overboost phase and the subsequent regeneration ⁇ phase. This is usually the maximum allowable
- control unit is preferably designed so that it controls the electric drive so that this torque ⁇ trash compensation over a defined number of
- control unit may be designed such that it controls the electric drive so that during the overboost phase of the supercharger, the torque achieved thereby is increased by the static torque of the supercharger.
- Invention is therefore already provided during the actual overboost phase an increased torque available, which is composed of the maximum allowable torque of the internal combustion engine and the static torque of the electric drive.
- the control unit ensures in particular that this increased torque during the overboost phase and during the regeneration phase of the supercharger after the overboost phase
- FIG. 1 shows a schematic representation of the drive of a
- Figure 2 is a diagram showing the torque curve as a function of time in carrying out a first variant of the method according to the invention
- Figure 3 is a diagram showing the torque curve as a function of time when carrying out a second variant of the method according to the invention.
- Figure 1 shows schematically the drive of a hybrid vehicle having an internal combustion engine 1 and an electric drive 6, which have a common output shaft 9, as shown schematically.
- the internal combustion engine 1 is associated with an air inlet duct 2, in which a supercharger 4 driven by a turbine 5 is located. Fuel supply devices for the internal combustion engine are not shown. Furthermore, the internal combustion engine has a Exhaust duct 3, in which the turbine 5 is located to drive the supercharger 4. The turbine 5 is bypassed by a bypass passage in which a valve is located.
- the internal combustion engine 1, the supercharger 4 with turbine 5 and the electric drive 6 are controlled by a control unit 8, wherein the electric drive 6 is connected to the control unit 8 via an inverter 7.
- the control unit 8 detects the end of an overboost phase of the turbocharger 4 or the start of a subsequent regeneration phase.
- Overboost phase generates torque equivalent.
- a constant torque is provided during the overboost phase and the subsequent regeneration phase.
- Regeneration phase is compensated by the torque generated by the electric drive.
- Overboost phase can be generated, which turns out alternately Turbocharger overboost phases and turbocharger regeneration phases combined with electric propulsion phases composed.
- FIG. 2 shows a diagram in which the torque curve as a function of time when performing a first variant of the method according to the invention is shown.
- the course of the torque (TQ) on the clutch over time is shown by the solid line 10.
- TQ torque on the clutch over time

- the curve of the torque TQ as a function of the time t is shown by the solid line 20.
- the output shaft is additionally subjected to the static torque of the electric drive during the overboost phase 21 of the supercharger, so that there is already an increased torque during the overboost phase 21. This increased torque will then during the following
