Definitions
- the invention relates to a method for controlling an automated clutch, which comprises a hydraulic clutch actuation system with a hydrostatic actuator whose pressure is detected.
- German published patent applications DE 101 27 765 A1 and DE 102 13 946 A1 disclose methods for controlling an automated clutch in which engine torque signals and engine speed signals are used to determine correction quantities.
- German patent application DE 10 2009 009 145 A1 a clutch system with a hydrostatic clutch release system is known, wherein deviations of an opening behavior of a connection opening are detected by the pressure behavior of the clutch release system is determined in dependence on an operating speed of a master cylinder piston.
- the evaluation of the pressure conditions depending on the actuating travel of the clutch can be effected by means of a pressure sensor which is integrated in the clutch release system, for example in the master cylinder or slave cylinder or in the pressure line.
- the position of the connection opening or the virtual position of a point at which the Kupplungsaus Wegsystem starts at a predetermined speed of the master cylinder piston to initiate movement on diaphragm spring tongues can be determined from a comparison of the position of a touch point of the friction clutch at different operating speeds of the master cylinder piston. Such a determination can be made redundant to the determined pressure sensor measured values or alternatively to these, if no pressure sensor is provided.
- the setting of the touch point requires a certain pressure on the slave cylinder, so that even here an indirect pressure detection can be done without pressure sensor.
- the object of the invention is to improve the clutch characteristic adaptation in clutches, especially in directly operated double clutches.
- the object is achieved in a method for controlling an automated clutch, which comprises a hydraulic clutch actuation system with a hydrostatic actuator whose pressure is detected, by using the pressure of the hydrostatic actuator for clutch characteristic adaptation.
- the pressure of the hydrostatic actuator is detected by a pressure sensor on the master cylinder.
- the pressure can also be detected at another point of the hydraulic path of the clutch actuation system.
- the knowledge of the clutch characteristic and in particular the touch point of the clutch is of crucial importance in order to achieve a high level of ride comfort of motor vehicles with automated clutch or automated manual transmission. Since the clutch characteristic can vary widely from vehicle to vehicle and over the service life of one and the same vehicle, various adaptation mechanisms are used to permanently track the clutch control to the actual behavior of a given clutch.
- the use according to the invention of pressure information for the clutch characteristic adaptation has the advantage that it functions independently of the determination of an engine reference torque in idling phases of the motor vehicle. As a result, a clutch characteristic adaptation of automated clutches in connection with hybrid drives or a start / stop functionality is made possible in particular.
- a preferred embodiment of the method is characterized in that a pressure signal of the hydrostatic actuator is used to adapt a touch point of the clutch.
- a further preferred embodiment of the method is characterized in that an evaluation of a drive train dynamics on the basis of torque and / or speed signals is used to adapt a coefficient of friction. According to an essential aspect of the invention, the touch point adaptation is thus decoupled from the friction value adaptation.
- a further preferred embodiment of the method is characterized in that the coupling is moved from a fully open position to a closed position, wherein the pressure of the hydrostatic actuator is only used for clutch characteristic adaptation when the pressure increases significantly.
- a so-called clearance that is, a working area without significant contact between driving and driven-side elements of the clutch, must first be overcome. In this area, a fairly low pressure level with little dependence on the travel of the actuator is expected.
- the clearance is overcome and the drive and output side elements of the clutch are pressed together, the increases Pressure in the hydrostatic or hydraulic path of the clutch actuator clearly. The position of the onset of pressure increase correlates with the sensing point of the clutch.
- a further preferred exemplary embodiment of the method is characterized in that the hydrostatic actuator is actuated with a gear set with a slow position ramp in order to determine the position of a significant increase in pressure. As it were, the course of the pressure signal is tested without any effect on the vehicle acceleration.
- the evaluation can also be model-based in regular operation.
- a further preferred embodiment of the method is characterized in that the coupling is actuated directly via the hydrostatic actuator and a master cylinder and a slave cylinder.
- Direct means that the hydrostatic pressure of the actuator acts on the clutch without the interposition of lever mechanisms.
- directly actuated clutches there is a relatively direct relationship between the master cylinder pressure, the clutch engagement force, and the clutch torque.
- a further preferred embodiment of the method is characterized in that the coefficient of friction of the coupling is correlated with the pressure signal of the hydrostatic actuator. If the clutch is closed beyond the touch point, the contact force within the clutch increases, and thus the torque transmittable by it, in accordance with the elasticities in the clutch and the actuation system. Especially with directly operated clutches with few friction points, the contact pressure of the clutch can be well correlated with the pressure signal in the hydrostatic section. As a result, the transmissible clutch torque is also closely linked to the pressure signal and can be approximately described by a proportional factor, which is also referred to as friction coefficient. This coefficient of friction can be adapted by considering the powertrain dynamics, in particular on the basis of engine torque and engine speed, to take into account, for example, changes due to temperature, aging or contamination effects in the controller.
- a further preferred embodiment of the method is characterized in that the clutch is moved from a fully open position to a closed position, wherein from the beginning of a significant increase of the pressure signal is closed to the position of the Kupplungstastcums.
- a further preferred embodiment of the method is characterized in that the Kupplungstast gleich is determined during normal driving from the course of the pressure signal.
- a further preferred embodiment of the method is characterized in that the coefficient of friction of the clutch is determined by correlation of the pressure signal of the hydrostatic actuator with a clutch torque determined from engine torque and engine speed.
- a further preferred embodiment of the method is characterized in that the pressure signal of the hydrostatic actuator is used directly as an additional controlled variable.
- the pressure signal may be returned to reduce a cross talk effect of the clutch.
- a further preferred embodiment of the method is characterized in that the pressure signal of the hydrostatic actuator is indirectly used by a pressure signal-based adaptation of form factors and / or crosstalk parameters. With the aid of the form factors different characteristic curves of couplings can be better approximated. Crosstalk models with crosstalk parameters can be used to compensate for the mutual influence of the clutch moments on dual clutches with simultaneous actuation of both partial clutches.
- FIG. 1 shows in simplified form a clutch actuation system 1 for an automated clutch, in particular an automated dual clutch.
- the clutch actuation system 1 is associated in a drive train of a motor vehicle designed as a double clutch friction clutch 10 and includes a master cylinder 4, which is connected via a designated as a pressure line hydraulic line 5 with a slave cylinder 6.
- a slave piston 7 is movable back and forth over an actuator 8 and with the interposition of a bearing 9, the executed as a double clutch friction clutch 10 is actuated.
- the master cylinder 4 is connectable via a connection opening with a surge tank 12.
- a master piston 14 is movable back and forth. From the master piston 14 is a piston rod 15, which is translationally movable in the longitudinal direction together with the master piston 14.
- the master piston 14 and the piston rod 15 are parts of an actuator 19 which is coupled to an electromotive actuator 20. Via the electromotive actuator 20, the actuator 19 executes longitudinal movements as a function of control signals of a control, which are transmitted via the master piston 14 to the hydrostatic or hydraulic path which comprises the master cylinder 4 and the slave cylinder 6.
- the hydraulic pressure in the hydraulic or hydrostatic path is detected by means of a pressure sensor 30 which is attached to the master cylinder 4.
- the pressure sensor 30 supplies a pressure signal, which is also referred to as actuator pressure signal.
- the transmissible clutch torque is approximately described by a proportional factor, which is also referred to as friction coefficient.
- the solution according to the invention can be implemented in various control algorithms.
- slow position ramps can be used to determine the position of an incipient significant pressure increase from the course of the pressure signal.
- the pressure signal can also during normal driving for Purpose of the clutch adaptation are evaluated.
- further parameters can be taken into account in the control algorithms for the automated coupling system, in order to allow a better adaptation of the control-internal models to the individually different real couplings.
