- Exhaust gas turbocharger and a second exhaust gas turbocharger and at least one electric machine wherein the exhaust gas turbochargers are connected in series, wherein at least the second exhaust gas turbocharger has means for varying its power, wherein the power of at least the second exhaust gas turbocharger in response to a requested desired torque of the
- the invention relates to a device for operating the above
- At least one of the exhaust gas turbochargers usually two exhaust gas turbochargers, each associated with means for influencing the power of the respective exhaust gas turbocharger.
- the means are, for example, electro-pneumatic actuators, actuatable wastegate valves and / or variable flow geometries.
- German Offenlegungsschrift DE 10 2007 012 303 A1 already discloses a method for operating a hybrid drive, which has an internal combustion engine and an electric machine as drive units, in which the electric machine is actuated, a deviation of an actual torque from a setpoint torque compensate.
- the method according to the invention with the features of claim 1 has the advantage that a delay of the torque build-up following a variation of the power of one of the exhaust gas turbochargers is compensated.
- the electric machine is controlled in dependence on the time of the variation in order to compensate for a deviation of an actual torque of the drive device from the desired torque.
- Electric machine is thus driven in response to a change in performance of the exhaust gas turbocharger, so that early on the electric machine is driven to generate a supporting drive torque.
- Exhaust gas turbocharger increased to increase the boost pressure, which leads to a higher torque of the internal combustion engine.
- the exhaust gas turbocharger dimensioned differently, it can also be provided that at
- Exceeding the first limit value is changed from the one exhaust gas turbocharger to the other exhaust gas turbocharger or switched.
- Exhaust gas turbocharger is varied such that the second exhaust gas turbocharger is connected only when the first limit value is exceeded.
- the second exhaust gas turbocharger is thus initially deactivated and does not contribute to the boost pressure control.
- the second exhaust gas turbocharger is associated with a bypass, in which an operable valve, in particular wastegate valve is located. By opening the valve, the exhaust gas flow past the turbine of the exhaust gas turbocharger, so that it is not driven by the exhaust gas.
- the first exhaust gas turbocharger also has means for varying its power, wherein the power of the first
- Exhaust gas turbocharger is varied in response to the requested target torque. Alternatively, it may be provided that the power of the
- Exhaust gas turbocharger alone from the turbine supplied exhaust gas mass flow of the internal combustion engine can be influenced.
- a bypass with a switchable valve is also associated with the first exhaust gas turbocharger, through which the exhaust gas mass flow of the internal combustion engine can be guided past the turbine of the first exhaust gas turbocharger.
- the power of the second exhaust gas turbocharger can be varied by the valve of the associated bypass.
- the current actual speed or the current boost pressure of at least the second exhaust gas turbocharger is detected, and that the timing of the variation in

- Variation is determined depending on the BetuschistsistSh or the actuator position / manipulated variable.
- the BetuschistSh or the actuator position / manipulated variable.
- control of the electric machine is terminated, in particular in response to a hysteresis, when the actual speed and / or the BetreliistsistGra a target speed
- Actuation target state it can be assumed that the second exhaust gas turbocharger has reached its desired performance. Thus, the support of the electric machine can be stopped. Due to the advantageous hysteresis is taken into account that due to the fluid dynamics conditions in the air system of the combustion engine, the charge pressure increases delayed to the increase in output of the exhaust gas turbocharger.
- Hysteresis circuit is thus ensured that the support by the electric machine is not terminated prematurely.
- the electric machine is advantageously controlled in response to a requested gear change.
- a short-term traction interruption during a switching operation can be compensated.
- the total torque provided by the drive device can be maintained even during a shift, which among other things, the change to the next transmission ratio improved and downshifts are avoided.
- the change to the next transmission ratio improved and downshifts are avoided.
- Electric machine can be compensated, prevented the downshift and instead controlled the electric machine accordingly.
- the required additional power or the required torque of the electric machine determined to the
- the device according to the invention with the features of claim 9 is characterized by a specially prepared control unit, the
- inventive method performs under normal use. This results in the already mentioned advantages.
- the drive device according to the invention with the features of claim 10 is characterized by the device according to the invention. This results in the already mentioned advantages.
- Figure 2 shows a method for operating the drive device
- FIG. 3 shows a further method for operating the drive device.
- FIG. 1 shows a simplified representation of a drive device 1 of a motor vehicle not shown here.
- the drive device 1 has an internal combustion engine 2, which is designed as a tension piston engine.
- Internal combustion engine 2 is connected to an electric machine 3.
- a rotor of the electric machine 3 is arranged rotationally fixed directly on the crankshaft 2 or the output shaft of the internal combustion engine 2.
- Electric machine 3 is in turn connected to a transmission 4, which connects the drive device 1 with drive wheels of the motor vehicle.
- the Transmission 4 has in particular several gear ratios, between which can be changed.
- the internal combustion engine 2 is associated with two exhaust gas turbochargers 5 and 6, which are connected in series with each other. Both exhaust-gas turbochargers 5, 6 each have a turbine T 5 , T 6 and a compressor V 5 and V 6 connected to the turbine.
- the exhaust gas turbochargers 5 and 6 are connected in series with each other, so that exhaust gas coming from the engine 2 is first supplied to the turbine T 6 of the exhaust gas turbocharger 6 and then to the turbine T 5 of the exhaust gas turbocharger 5. Accordingly, fresh air is first supplied to the compressor V 5 of the exhaust gas turbocharger 5 and then to the compressor V 6 of the exhaust gas turbocharger 6, so that the fresh air is compressed by the compressor V 5 and then the compressor V 6 and only then the internal combustion engine 2 is supplied.
- the turbines T 5 and T 6 are each assigned a bypass B 5 or B 6 , each having a switchable wastegate valve W 5 or W 6 , by means of which a flow cross section of the respective bypass B 5 , B 6 , is adjustable. If the respective bypass B 5 , B 6 is completely closed by the respective wastegate valve W 5 , W 6 , then the exhaust gas or the exhaust gas mass flow of the internal combustion engine 2 is completely guided by the turbines T 6 and T 5 to the two exhaust gas turbochargers T 5 and T 6 drive.
- the compressor V 6 another bypass BV 6 is associated with another valve WV 6 , through which the compressor V 6 supplied fresh air flow is adjustable.
- the wastegate valves W 5, W 6 and WV 6 represent, in particular, means for varying the power of the respective exhaust-gas turbocharger 5, 6. By actuating the waste -gate valves W 5 and W 6, it is possible, for example during operation of the
- Drive device 1 is a switching from a 2-stage operation, in which both exhaust gas turbochargers 5, 6 are operated, to a single-stage operation, in which only one of the exhaust gas turbocharger 5 or 6 is operated, are switched. In such a switch there is a delayed boost pressure buildup of the internal combustion engine 2 due to fluid dynamic conditions in the air duct system. As a result, the actual torque of the drive device 1 follows a delayed predetermined by a driver or requested by a driver target torque of the drive device. 1
- the electric machine is driven to a
- the power of the exhaust gas turbocharger 6 is varied by the control of the bypass. It is provided that the wastegate valve W 6 , as well as the other Wastegate- valves, a particular electric-pneumatic actuator is assigned, which moves the respective valve accordingly or operated. The actuator is driven in particular with a predeterminable duty cycle, in dependence of which a specifiable position of the respective valve results.
- the duty cycle is monitored continuously, in response to the actuating position of the actuator, the performance of
- Combustion engine 2 not immediately representable share of the torque increase to compensate.
- the electric machine 3 is taken so early in operation that for the driver or occupant of a drive device 1 having motor vehicle, a uniform torque increase and in particular, no interruption of traction is noticeable.
- the time of switching is advantageously set such that the
- Additional torque of the electric machine 3 acts vorumblend and thereby a speed drop is avoided.
- This can be implemented for example by a control logic of the control unit 7 as a function of the determined time of
- FIG. 2 shows in a simplified representation a method for operating the drive device 1, in which the time of the changeover to
- a step 8 the actuator of the wastegate valve 6 is driven to set a target duty ratio (E PWsoii). From the actuator's characteristic results in dependence on the electric current, a desired duty cycle from which an actual duty cycle TV or an actual position of the wastegate valve 6 results. As a result, the duty cycle TV of the actuator and, as a result, the time T are determined at which a variation of the power of the exhaust gas turbocharger 6 takes place. Depending on this duty cycle TV or time, the electric machine 3 is driven, wherein a release hysteresis in the following step 9 is used to control the electric machine 3.
- a target duty ratio E PWsoii
- Traction interruption of the transmission 4 is bridged during the switching operation.
- the torque of the drive device 1 can also be kept at a higher level during the switching process, which improves the connection of the next gear ratio and Avoid downshifts.
- the advantage in an additional torque assistance by the electric machine 3 as a function of a gear change, is the avoidance of traction loss and the avoidance of a downshift, since a higher gear can be used longer by the electric auxiliary drive.
- FIG. 3 shows, for example, the additional power P to be provided by the electric machine 3 or the additional torque to be made available as a function of different gear changes G between the gears 1, 2, 3, 4 and 5 of the transmission 4.
