Definitions
- the invention relates to a method for the automated actuation of a friction clutch in a drive train of a motor vehicle by means of a hydrostatic system with one of an electrically driven master cylinder of a hydrostatic clutch actuator, a friction clutch operating slave cylinder and a pressure line arranged between these pressure chamber, wherein a snooping operation by displacing the Donor cylinder is introduced in a non-pressurized state of the friction clutch by the pressure volume connected to a non-pressurized reservoir and a pressure compensation is provided.
- Clutch actuator for actuating a friction clutch of a drive train of a motor vehicle is moved by means of an electric motor, a master cylinder, which is connected via a hydrostatic pressure line with a slave cylinder.
- a force is transmitted to the slave cylinder via the hydrostatic pressure line.
- the liquid contained in a pressure volume formed by the slave cylinder, the master cylinder and the hydrostatic pressure line is subjected to volume changes due to external influences, for example temperature influences. With the same master cylinder position, these volume changes lead to a displacement of the slave cylinder.
- the position of the slave cylinder In order to transmit the requested clutch torque, the position of the slave cylinder must be known with sufficient accuracy.
- the master cylinder In order to compensate occurring volume changes in the hydrostatic pressure volume, the master cylinder is moved in a so-called sniffing process so that a connection is made between the pressure volume and a non-pressurized reservoir via an existing opening in the master cylinder. This allows a volume balance between the reservoir and the pressure volume done. Thereafter, there is again a known relationship between the position of the master cylinder and the position of the slave cylinder.
- a snooping process is carried out as a forcibly compressed (normally open) or as a force-forcibly pushed (normally closed) friction clutch when the clutch is disengaged or engaged. Due to its duration, a snooping process has a not insignificant influence on the driving behavior.
- the object of the invention is the development of a method for controlling a
- Friction clutch by means of a hydrostatic system, in which Schnuffelvor réelle to produce a high ride comfort and to reduce avoidable delays of shifts are performed in an efficient frequency.
- a sniffer is dependent on a multi-level, continuously formed from several operating variables of the motor vehicle, a confidence measure for a safe operation of the friction clutch forming scale performed.
- the proposed method is particularly advantageous, in particular in the case of a forced friction clutch, since the operating times of an opened friction clutch during driving of the motor vehicle are less frequent or less long even with double clutches compared to the closed states.
- the need to perform a snooping operation is determined by a multi-level scale that provides a measure of confidence in the position of the slave cylinder and thus the current clutch torque transmitted through the friction clutch.
- the scale may be formed, for example, from "high” confidence that no snooping is requested and executed to "no" confidence that the activation of the friction clutch is restricted or disabled.
- the intervening stages indicate a prioritized need for snooping, and depending on the level determined, a high priority snooping operation occurs immediately, resetting other operations, such as shifts, or at a lower priority level, after such operations.
- the formation of the scale preferably takes place by means of a first operating variable in the form of a temperature or a temperature change compared to a last-performed snooping operation of the printing volume.
- the first operating variable is formed on the basis of a temperature model from a single or a plurality of temperature sensors weighted depending on their influence on the temperature of the pressure volume.
- a temperature quantity is related to a temperature change of the pressure line since the last sniffing.
- a change in temperature causes due to the temperature-dependent expansion coefficient of the pressure medium, a pressure change, which leads to an undesirable, possibly due to the fixed position of the master cylinder piston not negligible loading of the slave cylinder, which optionally low actuation of the friction clutch has the consequence.
- the predetermined characteristic of the clutch torque to be transmitted based on a path of the slave cylinder piston and thus an associated path of the master cylinder piston whose path is again used to control the clutch actuator by the encoder cylinder piston driving electric motor is controlled accordingly.
- the hydraulic path of the pressure volume is thus detuned.
- a threshold value may be, for example, about 5 Nm.
- a temperature sensor may be provided in the pressure line.
- a temperature model which determines the temperature of the pressure line as a weighted average of temperatures that are in contact with the hydrostatic system.
- This can be, for example, an engine compartment, engine cooling water and / or transmission temperature of an internal combustion engine or transmission of the drive train of the motor vehicle.
- the weighting of the individual temperatures for determining the temperature modeled in this way depends on the respective influence and thus on the respective application and is adjusted accordingly to this.
- a determination of the temperature T of the pressure line or the pressure volume can be determined by the following equation (1):
- Ti are the individual temperatures and Wi are the associated weighting factors for temperature sensors in the engine “Eng", in the air “Air” and / or in a gearbox “Gearbox”.
- the modeled temperature of the pressure line or the pressure volume of the pressure medium is stored at this time after each successful sniffing and determined from this currently calculated temperature a temperature difference since the last snooping. If this temperature difference exceeds a defined threshold len, it is concluded that a sufficiently large change in volume of the pressure medium in the pressure line, that due to the temperature criterion, a higher need to perform a snooping is given. Accordingly, if necessary, a higher level of the scale is set.
- An alternative or preferably additionally forming the scale second operating variable may be formed from a pressure or a pressure change compared to a last performed snooping.
- a direct detection of the pressure can be determined directly, for example, on the basis of a pressure sensor provided in the pressure volume.
- a third variable can be formed from a currently determined touch point or one compared to a last-determined touch point or sniffing process of the friction clutch.
- a touch point information can be determined from a clutch model, which is spanned on the basis of torque, speed and / or pressure variables and receives corresponding information for updating from continuously determined sensor data.
- the torque actually transmitted differs from the torque calculated in the clutch model at the current master cylinder position.
- the change in the pressure volume in the hydrostatic path can be read directly from the touch point shift.
- the touch point of the friction clutch is stored after sniffing and determined with the current touch point, the Tasthuidifferenz since the last sniffing. If the touch point change exceeds a defined threshold value, a detuned hydrostatic path is closed. Accordingly, based on the Tast Vietnameseriums a level of the scale is set, which prioritizes a snooping higher.
- a scale for prioritizing a sniffing operation can be used in particular in so-called dual-clutch transmissions with a two actuated by a respective hydrostatic clutch actuator friction clutch, wherein for each friction clutch a separate multi-level scale for assessing a confidence measure of the friction clutches with an optionally be performed snooping is provided.
- a fourth operating variable of a first friction clutch by means of a currently determined touch point or a touch point change since a last touch probe point determination or a last snooping operation of the other friction clutch is formed.
- a snooping operation on an open friction clutch can be carried out by using as the fourth operating variable a currently determined value of the touch point of the other momentum transferring friction clutch.
- the two clutch actuators adjacent to each other so that the environmental influences that lead to a detuning of the hydrostatic path of a friction clutch, also act on the hydrostatic path of the other friction clutch in at least a similar manner, from Tastreteverschiebungen of a friction clutch on the moods in the hydrostatic section of the other friction clutch are closed.
- the Tastriostddlingverschiebung a currently adapted friction clutch also provides clues to the Schnüffelnötwendix on not adapted, that is currently sniffed friction clutch.
- the touch point of a first friction clutch can be stored during a snooping operation and based on a change in the touch point of the first friction clutch can be used as an estimate for the Tast Vietnamese selectedung the second friction clutch. If the thresholds estimated from the touch point change of the other friction clutch exceed defined thresholds, a higher need for a snooping operation is detected and the level of the scale for the corresponding friction clutch is correspondingly changed.
- FIG. 1 shows a diagram for depicting the dependency of the transmitted clutch moments of a friction clutch from one way of the master cylinder piston
- Figure 2 is a diagram illustrating a dependence of the clutch torque of
- FIG. 1 shows the two-part diagram 1 of the pressure p in a hydraulic path of a hydrostatic system for actuating a friction clutch with a hydrostatic clutch actuator whose controlled electric motor displaces a piston of a master cylinder to the pressure p in a filled with pressure medium with a predetermined pressure volume hydrostatic Range to which a slave cylinder is connected to vary.
- the slave cylinder piston is displaced depending on the built-up of the master cylinder pressure p and from this the friction clutch along an actuation path depending on the design - here along a Einschwegs a depressed friction clutch - on or disengaged.
- each waypoint s Gx of the curve 2 of the pressure p via the master cylinder piston stroke s G in accordance with the curve 3 of the pressure p via the clutch torque M RK of the friction clutch, a predetermined clutch torque M RKx transferable. If, however, the pressure p changes in the hydrostatic path because, for example, temperature changes occur, this assignment is disturbed. If such a detuning of the hydraulic path is detected, the displacement range As s is set on the master cylinder, in which a connection between the hydrostatic line and a non-pressurized reservoir produced and a pressure equalization is established, so that the original assignment of the master cylinder piston stroke s G to the Clutch torque MRK over the pressure p is restored.
- This process is called a snooping process.
- Performing a snooping operation requires the state of an open friction clutch and takes time.
- required circuits of a downstream transmission which require an actuation of the friction clutch, delayed and disturbed in frequent snooping the ride comfort. Therefore, a method is used in which the number of sniffing operations is reduced without neglecting the quality of the illustrated mapping of the clutch torque M RK to the master cylinder piston travel s G ZU.
- a multi-level scale is provided which indicates a measure of confidence for the operation of the friction clutch.
- the levels of the scale are formed by the temperatures prevailing at the hydrostatic path, the pressure which is being set and information about a change in the touch point, and they give confidence. according to which it is judged how urgent a snooping process is. Depending on the urgency, a snooping process is carried out immediately and delayed.
- FIG. 2 shows the diagram 4 for illustrating the influence of detuning
- Coupling characteristics 5, 6 with the clutch torque M RK on the Geberzylinderkolbenweg s G The characteristic curve 5 shows the relationship of the clutch torque M RK on the Geberzylinderkolbenweg s G based on a stored in a control unit, adaptable clutch model with the currently adapted touch point TP M.
- the characteristic curve 6 shows the relationship of the clutch torque M RK on the Geberzylinderkolbenweg s G in example detuned as a result of a change in temperature hydraulic path. In this case, as a result of the changed pressure conditions in the hydraulic section, the touch point TP M of the clutch model is displaced to the real touch point TP R by the higher pressure being applied to the slave cylinder.
- the characteristics 5, 6 are shifted from each other under otherwise identical conditions, so that when set Geberzylinderkolbenweg s Gx a torque difference corresponding to the double arrow 7 is set.
- the multi-level scale can be given a confidence measure reflecting the need for a snooping operation.
