Definitions
- the invention relates to a method for controlling a drive train of a motor vehicle with an internal combustion engine with a crankshaft and an at least one transmission input shaft containing automated transmission and each one at least one transmission input shaft to the crankshaft connecting, automated friction clutch, depending on a desired by a driver driving a Driving program, the internal combustion engine, gear change in the transmission and controls the at least one friction clutch.
- a desired by the driver and by means of appropriate controls such as accelerator pedal for notifying a desired driver request torque, a brake pedal, a shift or selector lever and the like of a control unit communicated driving situation by the controller by means of a driving program running, for example, the control of the internal combustion engine, the gear change of Transmission, actuation operations of the friction clutch by means of predetermined operating parameters such as switching points such as engine speed limits, slip behavior of the friction clutch, speed limitations of the internal combustion engine, torque interventions in the internal combustion engine and the like performs.
- the transmission can be configured as a double-clutch transmission with two partial transmissions, each with a transmission input shaft and each connecting them with the crankshaft friction clutch, the motor vehicle driven by each active partial transmission with the friction clutch closed and inserted in the passive part of the transmission with the friction clutch open the subsequent course and a Circuit is performed by overlapping the moment of the two friction clutches.
- the drive train In the new state of the motor vehicle, the drive train must be retracted, with appropriate Einfahrvorschriften be observed by the driver. In particular, the engine may not be exposed to high speeds and also the friction clutches (s) should be retracted properly. Failure to comply with these regulations can permanently damage the drive train.
- the object of the invention is therefore to propose a method in which the driver is relieved of the responsibility for compliance with the driving-in regulations.
- the object is achieved by a method for controlling a drive train of a motor vehicle having an internal combustion engine with a crankshaft and an automated transmission containing at least one transmission input shaft, and an automated friction clutch connecting the at least one transmission input shaft to the crankshaft, depending on a desired by a driver Driving situation, a driving program, the internal combustion engine, gear change in the transmission and the at least one friction clutch controls and is operated until exceeding a predetermined threshold of total vehicle power of the driving program in a retraction and then in normal operation.
- automated systems in motor vehicles such as automated friction clutches and automated manual transmissions such as dual-clutch transmissions to support the Einfahr perspectives by the Anêtsoftware means of a suitable Einfahrmodus.
- the total driving power can be done for example by evaluation of the odometer.
- variables representing the overall driving performance for example the service life of the internal combustion engine, engine parameters integrated over time, such as fuel consumption, emitted engine torque, rotational speed and their combinations, a torque transmitted via the friction clutch (s) and the like can be used.
- switching points of the switching from an engaged to a higher gear in the run-in operation can be provided at reduced rotational speeds of the crankshaft compared to the normal operation.
- a normal switching program sequence in normal operation for example in drive trains with dual-clutch transmission (PSG) are advantageously supplemented by the upshift already takes place in the run-in operation very early, so that safely high speeds can be avoided, for example, a high slip on the Moment transfer friction clutch when switching or re-engage and also can be unfavorable for the internal combustion engine in the break-in phase.
- the switching points of the retracting operation can be adjusted exceptionally depending on selected driving situations the switching points of normal operation.
- the driving program in the running mode exceptionally and to a driving situation allow limited higher switching points, for example, if the selected driving situations emergency situations, kick-down states or the like.
- this may also include a power of the internal combustion engine which may be limited in the run-in mode be briefly re-admitted.
- the electric machine the power loss - as far as a state of the storage device for electrical energy allows - compensate.
- a starting process of the motor vehicle in the run-in operation can be provided with respect to the normal operation with less slippage of the friction clutch.
- the nominal rotational speed curve can be modified in such a way that the slip performance, that is to say the friction or friction energy introduced into the friction clutch, is reduced.
- the starting speeds can be reduced. As a result, the power input is reduced in the friction clutch while maintaining the ride comfort.
- protective measures for the at least one friction clutch can be initiated in the run-in mode at smaller clutch temperatures than in normal operation.
- Protective measures may include, for example, when exceeding a predetermined and lowered in driving temperature threshold faster closing the friction clutch with a lower Reibendemeintrag in the friction clutch to forced opening or forced closing with decommissioning of the transmission or in a dual-clutch transmission or the affected sub-transmission to be understood.
- such protective measures can be reduced instead of at coupling temperatures of 300 e in normal operation to 200 ° in the run-in.
- an idling rotational speed of the internal combustion engine can be restricted in relation to a permissible rotational speed in normal operation.
- it can be provided by an intervention in the control of the internal combustion engine, in the running-in operation, for example in the park or neutral position of the transmission when the accelerator pedal is operated by the driver, the speed of the internal combustion engine is limited to, for example, 2000 revolutions per minute.
- a tolerance window can be provided in the range of the threshold of the total driving power and, within this tolerance window, parameters of the retracting operation characterizing the running-in operation can be adapted to the corresponding operating parameters of the normal operation.
- a sliding transition of the retracting operation into the normal operation takes place in an advantageous manner. Such a transition can take place by means of steps that are preferably imperceptible by the driver or continuously.
- the run-in parameters can be transferred together at a common threshold of the total driving power and by means of a common tolerance window from the run-in to normal operation.
- different thresholds for the total driving power and / or different tolerance windows can be provided for two or more entry parameters.
- the inventive concept may further be provided to briefly reactivate the conditions such as operating parameter of the run-in operation after exceeding the threshold of the total drive power and the operation of the drive train during normal operation, for example if a predefinable threshold of an operating parameter relevant to the drive motor is fallen short of.
- Relevant operating parameters for an internal combustion engine may be, for example, the engine oil temperature or the cooling water temperature.
- this threshold it is conceivable to extend this threshold to powertrain-relevant components and their characteristics, such as, for example, the transmission oil temperature. After exceeding this threshold, normal operation is reactivated.
