Definitions
- the invention relates to a method for controlling a clutch of an electronic clutch management system (EKM) and / or an automated gearbox (ASG). Furthermore, the invention relates to a device for actuating a clutch with a motor, which is coupled to a release system via a transmission.
- EKM electronic clutch management system
- ASG automated gearbox
- Such a method and such a device are known from vehicle technology.
- the invention has for its object to propose a method and a device according to the types mentioned, which avoid the disadvantages known from the prior art.
- this object is achieved in that a gripping point of the clutch is determined as a function of the clutch temperature and is taken into account when the clutch is actuated.
- a suitable modification e.g. the torque characteristic and / or the clutch control. It is possible that after an energy input into the clutch, which increases the clutch temperature, a change in the torque characteristic on the clutch occurs. This can negatively affect the function and comfort e.g. affect automatic clutch control.
- the effects of the thermal effects in an automated clutch control are preferably determined for the compensation by taking the clutch temperature into account when determining the gripping point.
- the position of the plate spring tongues of the clutch to be shifted after an energy input with the aid of measurement technology in the vehicle and / or a test bench, in particular an EKM functional test bench.
- the gripping point is a decisive variable for the control of an automated clutch or the like.
- the gripping point corresponds to the path of the actuator to a predetermined point, which preferably corresponds to a clutch torque of approximately 9 Nm.
- the gripping point is not constant, but can e.g. also change by introducing energy into the clutch.
- the displacement of the gripping point when the vehicle is crawling is considered as an example.
- the position of the plate spring tongues is shifted when the clutch is closed. This results in a change of the actuator gripping point if the so-called sniffing function is not activated.
- the torque characteristic of the clutch is also changed. This also results in a change in the actuator gripping point.
- Sniff function is activated.
- the sniffer function When the sniffer function is activated, only the torque characteristic of the clutch is preferably changed.
- the change in the gripping point is calculated in relation to an initial state within a short time range, for example ⁇ 3 min, and is taken into account in the control of the automated clutch.
- the coupling temperature can, for example, briefly, eg during a creep process change several approaches in a row and / or during a traffic jam on the mountain. It can be important whether the sniff function is activated or not. It has been shown that there may be no long-term or absolute dependence of the gripping point on the coupling temperature.
- Other influences on the gripping point can also be important, such as, for example, the temperature distribution within the clutch, in particular a self-adjusting clutch (SAG), adjusting the clutch, in particular an SAC clutch, setting the main actuator spring and / or setting or
- Energy input is integrated into the EKM control so that the functionality and comfort can be improved by controlling the automatic clutch.
- the energy input per journey can be less than 50 kJ.
- the friction power can be less than 2 kW.
- a light stall test can be carried out before and after each start-up program, in which the accelerator pedal is pressed to determine the torque characteristic of the clutch.
- the gripping point can be determined using the torque characteristics of the coupling determined during the stall test.
- the clutch temperature can be calculated using an EKM temperature model, whereby the temperature of the pressure plate, the path of the central release and the pressure are used as measured variables. It is conceivable that other measured variables are also used. The measurement results are shown in the table below:
- gripping point When the term gripping point is used in general, the gripping point with respect to the actuator travel can preferably be considered. When examining the processes on the clutch, a distinction is made between the clutch gripping point and the actuator gripping point.
- the clutch gripping point is the disengagement path of the clutch at a predetermined point, which is present on the torque characteristic curve of the clutch at 9 Nm.
- the release path begins with the clutch closed, ie the clutch zero point.
- the clutch grip point only includes the influence of the clutch.
- the actuator gripping point is the path of the actuator at the point at which the torque characteristic of the clutch 9 Nm are present.
- the Swiftrweg begins at a so-called sniffing position, ie the
- the actuator gripping point includes influences of the clutch and the
- the actuator gripping point can be influenced in particular by shifting the tongue position when the clutch is closed. This corresponds to a parallel shift of the characteristic of the clutch torque including the zero point of the clutch. It follows that the zero point of the clutch is not equal to the zero point of the actuator. This in turn means that there is a parallel shift in the characteristic curve of the clutch torque f (Stellerweg). The actuator gripping point thus changes. When sniffing, the two zero points can be compared, i.e. the zero point of the clutch is equal to the zero point of the actuator.
- the clutch torque f characteristic curve (Stellerweg) is similar again as before.
- the actuator gripping point can be calculated depending on the pressure. Since the so-called sniffing has a significant influence on the actuator gripping point, an evaluation can be carried out both with and without the sniffing function.
- Tongue position i.e. the zero position of the clutch directly on the actuator G maturing point.
- the actuator gripping point can be calculated by compensating for the displacement of the tongue position by sniffing. Only the change of the clutch grip point is effective.
- the change in the gripping point can be calculated within a short time range of approximately less than 3 minutes and taken into account in the control.
- Coupling temperature can change briefly, for example during a crawl process, with multiple starts in succession and / or with a traffic jam on the mountain.
- increasing coupling temperature up to 300 ° C
- Clutch gripping point becomes smaller.
- the tongues can move towards the engine.
- the pressure, which corresponds to the release force, becomes smaller at the gripping point.
- the coupling temperature can be determined in particular using a suitable EKM temperature model.
- the shift of the actuator gripping point is taken into account in the EKM control, which advantageously enables an improvement in functionality and comfort.
- a short-term thermal effect is considered when energy is introduced into the clutch.
- the short-term displacement of the plate spring tongues is considered due to, for example, potting effects on the flywheel and / or on the pressure plate, in order to be able to preferably indicate effects on the EKM system.
- a lot of friction energy can be supplied to the clutch in a relatively short time, especially when starting at full load, starting bangs and / or stall tests.
- short-term, reversible shifts in the position of the plate spring tongues can occur, which are caused in particular by thermal deformation as a result of temperature gradients within the pressure plate and the flywheel. Furthermore, this can be dependent on the friction power supplied.
- long-term, reversible There is a shift in the position of the plate spring tongues, which is particularly dependent on the temperature of the clutch (pressure plate).
- the long-term shift in the position of the plate spring tongues can preferably be compensated for by the EKM control.
- the short-term displacement of the position of the plate spring tongues and the time for regression can preferably be proportional to the friction power supplied.
- the sniffing function can be prevented at least for a predetermined period.
- the friction power supplied to the clutch can e.g. are constantly determined by the EKM control system, using a suitable EKM clutch temperature model as the basis.
- test bench tests can be determined.
- a predetermined clutch is loaded in slipping phases with parameters which are listed in the table below.
- the clutch can then be closed and the position of the plate spring tongues determined.
- So-called potting effects can preferably be on the pressure plate and on the flywheel depending on their geometry.
- the short-term displacement ⁇ S of the plate spring tongues and the time t R in which this displacement is reduced by 90% can be evaluated accordingly. This results in a dependency between the short-term shift and the time for regression on the friction power supplied.
- the mean values of the evaluated slip phases are shown in the table below.
- the friction power supplied can be a product of the clutch torque and the slip number and can be calculated using the following equation:
- the short-term displacement of the position of the plate spring tongues and the time of the regression in the vehicle can preferably be proportionally dependent on the friction power supplied.
- the sniffing function should be deactivated, otherwise the release system will be adjusted to an incorrect clutch zero point, since sniffing will set the clutch zero point to the actuator zero point. If you sniff the disc spring tongues during this short-term shift, an incorrect actuating torque characteristic curve can result for all driving situations until the next sniffing after the shift has receded. This should be avoided in order to have a positive influence on the driving comfort of a vehicle with an automated clutch system.
- the frictional power supplied to the clutch is continuously determined by the EKM controller, the EKM clutch temperature model preferably being used again as the basis.
- the so-called sniffing ban can therefore be interpreted without great difficulty.
- a fully loaded vehicle can be stopped repeatedly on the mountain.
- the starting speeds may drop due to the excessive torque transmission, so that under certain circumstances starting at a 30% gradient is not possible.
- dragging moments can also prevent gear selection.
- a suitable overtemperature can be recognized in time by suitable devices. It has been shown that a suitable control system for compensating should therefore be provided.
- the gripping point is adapted to the currently correct value and / or the deactivation of the coefficient of friction adaptation is provided. Furthermore, the stall takes place with a significant increase in temperature. Furthermore, the gripping point is adapted (catching up any shift). Then, by adapting the gripping point, the displacement is tracked during cooling. The sniffer function is activated before the gripping point is adapted. Then the gripping point is adapted to the correct value.
- the characteristic curve is shifted through the barn, which can be recognized by catching the gripping point.
- the characteristic curve can shift back when cooling.
- the shift takes place parallel to the gripping point shift of the characteristic curve when calculating NPUNKT (in b lag.c). As a result, the shift takes effect at the end of the status sequence when determining the new clutch target travel (KUPPLUNGSWEG_NORMIEREN in k_solnom.c) and also when querying the modulation limits etc. (e.g. DRIVING in s_fahr.c).
- a global variable (short) TEMP_ALT can be used for the calculation of the shift, which is set equal to the current temperature when SNOWING (in s ahr.c). This can also be done at the STEUERUNGJNIT (in m_ Kunststoff.c) and be provided during the initialization of the temperature when the engine starts (in t_temp.c), in particular to avoid or intercept jumps in temperature.
- the compensation can preferably be slowly reduced to 0 (in emp.c).
- intervention can be made, for example, at a relatively sensitive point in the control when the model temperature is used for the first time.
- the described compensation can advantageously avoid a dangerous self-amplification of the clutch torque when creeping continuously.
- the compensation can be used in particular in vehicles that are at operating temperature.
- the slight over- or under-compensation can possibly be caused by the fact that the temperature model (as the trigger of the shift) is not adapted to the warm-up phase of the vehicle. For this reason, an adaptation can be provided in order to also advantageously use the compensation in vehicles that are not at operating temperature.
- the model can deliver an excessively high temperature of 80-120 ° C, because the model involves cooling against a transmission bell at 100 ° C.
- the model is optimized to achieve high accuracy at high temperatures (where measures are also taken by the control). Accordingly, it is advisable that the known engine temperature be used as the transmission bell temperature in the temperature model. Other measures for optimizing the temperature model are also possible.
- the influence of characteristic fields on the compensation described is predetermined qualitatively. For example, if the grip point and / or the coefficient of friction is too low, the actual creep torque can be greater than the controlled one
- the compensation can preferably depend on whether the characteristic is correct. If the above-mentioned GP / RW error amplification leads to the instability of the adaptations, it could be checked whether the adaptation result is rejected if the amount of compensation is large.
- the object of the invention with respect to the device can be achieved in that a device for actuating a clutch with a motor, which is coupled to a disengagement system via a gearbox, is proposed, in which the gearbox enables a rotational-translational conversion, the The transmission has a high efficiency in the forward drive and a low efficiency in the reverse drive, so that the transmission is designed to be self-locking and / or self-braking when a load is applied.
- the device according to the invention can preferably be used in a vehicle with an electronic clutch management (EKM). This is intended in particular to keep the clutch actuator in a predetermined position without additional power consumption by the drive. Accordingly, a drive system is proposed which operates in the drive direction, i.e. Motor for load for round trip
- Return movement has a high efficiency and, conversely, has a lower efficiency, so that the entire transmission is self-holding, self-locking or self-braking without counteracting drive power.
- a double helical gear or the like can be provided in the gear.
- the double helical gear mechanism for the rotational-translational conversion can preferably have a ball screw drive or the like.
- a helical gear drive or the like can also be used within the scope of an advantageous development of the invention.
- the helical gear drive preferably comprises at least one pinion and a toothed rack.
- the device according to the invention can be integrated into an actuator which is used to actuate clutches.
- the helical gear unit can be used both as a single link and as an intermediate link in a strand which has a drive gear unit and an actuator gear unit for actuating clutches.
- the device according to the invention in a clutch actuator with a rotary and / or linear drive, intermediate or output for electromechanical and / or hydraulic actuation of a clutch and in combination with an electric drive and an incremental and / or absolute travel or angle measurement is used.

- the proposed device has the property of being self-locking or self-braking when subjected to external forces or moments.
- the force of the clutch spring is uncompensated or compensated by an opposing force or the resulting moment, which acts on the clutch spring
- Clutch actuator works, suitably compensated.
- a development of the invention can provide that a modified
- Helical gearbox is used, which e.g. is used in a shift and / or selector actuator of a manual transmission or in a clutch release system.
- the system-related high axial forces on the toothing e.g. can be used to actuate a brake or a mechanical, electrical or electromechanical system.
- the proposed drive system can also serve as a basis for other applications, so that, taking into account the respective properties of each application, use is also possible in these applications.
