Definitions
- the invention relates to a method for controlling a drive train, comprising an internal combustion engine, which is connected to a dual-clutch transmission, which has a first and a second partial transmission with at least one switchable transmission stage, wherein between the internal combustion engine and the first partial transmission, a first friction clutch and between the internal combustion engine and the second partial transmission, a second friction clutch is arranged, wherein an engine torque of the internal combustion engine is transmitted to the first or second partial transmission for providing a drive train torque at the output of the double clutch transmission by the first or the second friction clutch.
- a generic drive train with a parallel shift such as a dual-clutch transmission, known in which the engine torque of the internal combustion engine by means of a dual clutch with two friction clutches controlled by the two partial transmissions is transmitted to a transmission output.
- the transmission stages are switched and designed in the, a partial transmission associated open friction clutch.
- the actual circuit of the dual-clutch transmission takes place at in both partial transmissions engaged transmission stages by a so-called example from the
- WO 2007/124710 A1 known overlap circuit in which the closed friction clutch of a torque-transmitting partial transmission open and the open friction clutch of the other partial transmission is closed overlapping.
- the friction clutches are designed with respect to their transmission capacity so that at least the maximum engine torque at fully closed friction clutch is transferable.
- the engine torque and the clutch torques of the friction clutches are continuously determined or estimated over the service life. If it is determined that the transmission capacity for an applied engine torque is no longer sufficient, for example because of a prior damage of a friction lining, the engine torque is limited to the clutch torque that can still be transmitted via the affected friction clutch. This leads to power losses of the drive train in an operation of the sub-transmission with the restricted friction clutch.
- the invention has for its object to provide a method for controlling a drive train, in which Rupfschwingungen caused by the partial clutches of a dual clutch transmission, be reduced or avoided altogether.
- the object is achieved in that the drive train is monitored for occurrence of juddering vibrations and in the detection of
- Rupfschwingungen a regeneration process of one of the two partial clutches is triggered, wherein in the regeneration process, a friction lining is removed.
- This renewal of the friction lining of one of the two partial clutches during the regeneration process helps to reduce Rupfschwingungen and then the vehicle is back in a comfortable state.
- This regeneration process does not produce any perceptible changes by the vehicle occupants.
- the detection of the juddering vibrations is carried out by a
- Rupfbeobachter which activates or deactivates the regeneration process.
- a Rupfbeobachter is advantageous because the friction systems of the individual part clutches themselves differ and the regeneration process should only be used if it requires the state of the partial clutches.
- the juddering vibrations are compensated by a anti-skid control, wherein when exceeding a Rupfschwellhongs by an amplitude of Rupfschwingungen the regeneration process of the first or second partial clutch is triggered.
- the Rupfschwellwert is determined so that the regeneration process is always started when the traction control can no longer compensate for the juddering vibrations occurring.
- Rupfschwell value can be easily determined by software, when the
- Regeneration process is always carried out only on a partial clutch can be continued with the second, not subject to the regeneration process clutch without further effects on the handling of the vehicle.
- a load profile of the double clutch transmission is varied by the inactive and / or active partial clutch.
- Slip control the degree of abrasion of the friction lining of the inactive second clutch can be designed controlled.
- the active first split clutch remains during the
- the active first part clutch is during the
- Regeneration process open and the slip control reduces one of the first ten active part clutch transmitted Kupplungsmonnent to the clutch torque, which is transmitted from the inactive second part of the clutch. This ensures that the drive train torque, which is output by the dual-clutch transmission at its output, is kept constant, which is particularly important for a constant driving performance of importance.
- an increased slip rotational speed is generated in the inactive second partial clutch at a low ambient temperature of the drive train.
- an increased slip speed is generated at the inactive second clutch.
- the temperatures increase during the green phase at the partial clutch, which leads to an abrasion of the friction lining and thus to a renewal of the friction lining with increased slip of the partial clutch.
- wear on the inactive part clutch is generated in a light load blasting. This means that only at low juddering vibrations the surface of the inactive second clutch is removed and thus a new coating layer of the partial clutch comes into play.
- an engine torque of approximately 10 to 25 Nm is applied to the inactive part clutch. Based on such a low engine torque, the load on the drive train and thus a change in the drive train torque at the output of the dual clutch transmission is only insignificantly influenced and thus not perceived by the driver.
- Fig. 1 is a schematic representation of a drive train with a Doppelkupplungsge- transmission. The inventive method will be explained using the example of a drive train 1 with a dual-clutch transmission.
- Fig. 1 shows a schematic diagram of the drive train 1, as used in motor vehicles.
- This drive train 1 comprises an internal combustion engine 2 and two partial transmissions 3, 4.
- the connection of a partial transmission 3, 4 with the internal combustion engine 2 takes place via a respective partial clutch 5, 6, which are controlled by a control unit 15.
- the first partial transmission 3 carries the odd gears 7, while the second partial transmission 4 includes the straight gears 8.
- the gears 7 and 8 are in case of need connected to a transmission input shaft 9, 10 of a transmission 1 1, which drives the drive wheels 14 via an output shaft 12 and a differential 13.
- a gear 7 of a sub-transmission 3 is connected to the transmission input shaft 9, while the gear 8 of the other sub-transmission 4 is engaged.
- the behavior of the two partial clutches 5, 6 must be set accurately to avoid interference.
- a rotational speed sensor 16 which detects the rotational speed of the internal combustion engine 2
- a rotational speed sensor 17 which monitors the rotational speed at the transmission input shaft 9
- a slip rotational speed of the partial clutch 5 is determined by the control unit 15.
- Another speed sensor 18 is also connected to the control unit 15 and detects the speed at the transmission input shaft 10 for determining the slip speed of the partial clutch 6. This slip speed is detected in dependence on whether the partial clutches 5, 6 are closed or opened.
- the control unit 15 starts a regeneration process for the internal combustion engine.
- active partial clutch 6 of the dual-clutch transmission is subjected to the approximate total engine torque of the internal combustion engine 2.
- the transmission output shaft 1 1 thus a drive train torque for driving the drive wheels 14 is removed, which corresponds to the engine torque of the internal combustion engine 2.
- the second partial clutch 6 is in slip and is therefore inactive.
- the engine torque of 20 Nm which at the inactive part of the clutch. 6 is applied to subtract from the engine torque, which is transmitted from the engine 2 to the active part clutch 5. Due to the proposed solution, the load profile of the drive train is deliberately changed by the setting of the active or inactive part clutch 5, 6, so as to pass through critical situations such as juddering faster or even completely avoided.
