Definitions
- the invention relates to a method for controlling an automated friction clutch, which is arranged in a drive train of a motor vehicle between an internal combustion engine and a transmission, wherein an output from the engine engine torque is controlled in response to a coupling slip occurring at the friction clutch.
- German Offenlegungsschrift DE 10 2009 014 467 A1 discloses a method for
- tion motor is controlled in response to a slip occurring at the friction clutch.
- the object of the invention is the comfort and / or availability of an automated friction clutch, which is arranged in a drive train of a motor vehicle between an internal combustion engine and a transmission, wherein an output from the engine engine torque is controlled in response to a clutch slip occurring at the friction clutch to continue to improve.
- the object is in a method for controlling an automated friction clutch, which is arranged in a drive train of a motor vehicle between an internal combustion engine and a transmission, wherein an output from the engine engine torque is controlled in response to a clutch slip occurring at the friction clutch, achieved in that the engine torque is limited by an engagement torque engagement, which depends on a desired change in engine speed u> M 0 tor, __ ii.
- the engine speed ü or, soii should increase or decrease in compliance with a limitation of a recorded in the friction clutch friction.
- M E jr handle the change in the engine speed ⁇ ⁇ ⁇ ⁇ over time is taken into account.
- a preferred embodiment of the method is characterized in that the engine torque is limited by an engagement torque ⁇ ⁇ ⁇ ⁇ , 9 ⁇ ⁇ , which depends on an inertial moment J Mot or on an engine side of the friction clutch.
- Jutotor is the mass moment of inertia of the mass moved on the motor side of the friction clutch.
- a further preferred embodiment of the method is characterized in that the engagement torque ⁇ ⁇ 9 ⁇ «is limited in dependence on an offset moment Moprset, which is determined according to the following formula: rad
- J ⁇ ⁇ corresponds to the moment of inertia on the motor side of the clutch
- a further preferred embodiment of the method is characterized in that the engagement torque M E ingnfr is limited in dependence on a maximum allowable friction power Pumit.
- the maximum allowed friction power P order it depends on the clutch torque and / or the slip occurring.
- a further preferred embodiment of the method is characterized in that the engagement torque M Eing nff is determined according to the following formula: p
- M corresponds to the limit of limiting engine engagement torque and P Limil corresponds to the permitted maximum friction power.
- ⁇ a & Msip ⁇ corresponds to the slip speed at the clutch in Rad per second.
- J Moior corresponds to the moment of inertia on the motor side of the clutch and
- a further preferred embodiment of the method is characterized in that the maximum friction power P Limi t k is multiplied by a correction factor that caused by errors in the engine torque and / or clutch torque taken into account. By the correction factor k, the allowed maximum friction power P L
- a further preferred embodiment of the method is characterized in that the engine torque when starting, especially when starting on the mountain, by the engagement torque Bll handle is limited.
- the friction is indirectly reduced by a suitable reduction of the engine torque, while at the same time the highest possible driving comfort and high vehicle availability.
- the inventive method is a strategy for protecting an automated friction clutch, which is arranged in the drive train of a motor vehicle between an internal combustion engine and a transmission.
- registered in the friction clutch friction to protect the clutch from overload should be reduced.
- Prerequisite is a specified maximum friction, a known slip speed (difference between engine and transmission input speed) on the clutch to be protected and the possibility of a torque-limiting engine engagement on the drive motor.
- the registered friction corresponds to: rad
- the clutch torque In order to limit the registered friction power, the clutch torque must be limited depending on the clutch slip according to the above formula. Since at the same time the clutch slip is to be reduced or the engine speed should be adjusted to a certain value at the same time, in general, the engine torque must be limited by a corresponding intervention. This results in a constant engine speed and the corresponding clutch torque. If the engine speed increases or decreases in strict compliance with the power limitation, an additional offset for the engagement torque results after:
- J mol corresponds to the moment of inertia on the motor side of the coupling dm
- M i engagement corresponds to the limiting engine intervention and P Umit the dusted maximum friction.
- Clutch torque control which uses the engine torque as a reference variable, are usually already implemented, the pure engine intervention benefits in terms of control effort.
- a big advantage of the engine torque limitation is also that the engine torque in phases with (large) clutch slip has no direct effect on the acceleration of the vehicle, since the torque on the drive train is generated here essentially only by the clutch torque. The engine torque then only affects the engine speed curve.
- a correction factor k can be determined with the larger
- the process according to the invention preferably takes place in dual-clutch projects
- the method may be part of a delivery strategy in clutch control software for automated clutches.
- the method is mainly needed to protect against misuse in starting situations, for example, when the driver presses the accelerator pedal with fast forward rolling vehicle with engaged forward gear.
- the method can generally be used in all slippery driving situations.
