Definitions

• the invention relates to a method for operating a clutch in a vehicle with egg nem manual transmission, in which the manual transmission is operated manually and the clutch is automatically operated by a clutch actuator.
• EKM electronic clutch management
• the invention has for its object to provide a method for operating a clutch in egg nem vehicle, in which the time to open the clutch is reliably determined during a switching operation.
• the object is achieved in that after detection of a switching intention of the manual transmission, the clutch is opened in response to a driving mode of the Fahrzeu ges.
• the electronic clutch management system is signaled by electronic signals when exactly the clutch is to be opened, so that the manual gearshift operation can be performed by the driver.
• the shift intent is detected by a shift intention sensor.
• a shift intention sensor By means of this shift intention sensor, a physical quantity which is exerted by the touch of a shift lever of the manual transmission by the driver on the shift lever, can be detected, and thus the driver's shift intention to be recognized.
• a shift intention sensor on the shift lever of the manual transmission arranged path and / or force sensor is used.
• existing displacement sensors are used in the manual transmission for detecting the driver's intention to shift.
• the output signal of the shift intention sensor is compared with a threshold value, wherein when the threshold value is exceeded, an existing shift intent is concluded.
• the intention to shift can be detected particularly easily.
• the threshold value is changed depending on the driving mode of the vehicle. Since, depending on the driving mode of the vehicle, the sensitivity of a known switching intention to the opening of the clutch varies, the threshold must be adjusted accordingly.
• a fixed threshold is provided for each drive mode. Thus, only one threshold value is possible when the drive mode is detected.
• the threshold value can alternatively be filtered or derived independently of other vehicle parameters.
• the threshold value is varied in a given driving mode of the vehicle in dependence on predetermined vehicle parameters.
• a driving speed or damping of the vehicle can be used.
• a sensitivity is riiert depending on the determined driving mode va, which describes a relationship between the opening of the clutch actuation of the shift lever by the driver. This ensures that the shift intention is known early enough so that the clutch is opened early enough for the shift. On the other hand, the shift intent may not be recognized too early, otherwise the clutch is already open when the driver has not yet indicated the shift intent.
• 1 is a schematic diagram of an electronic clutch management system
• Fig. 2 shows an embodiment of an interconnection of the electronic clutch management system for carrying out the method.
• Fig. 1 is a schematic diagram of an electronic clutch management system 1 is shown, in which between a motor 2 and a transmission 3, a clutch 4 is arranged to.
• the transmission 3 is ver with the clutch 4 via a transmission input shaft 5 connected while the transmission output via a transmission output shaft 6 to the vehicle wheels 7 leads.
• the clutch 4 is actuated by a, comprising an electric motor 8 clutch actuator 9, wherein the electric motor 8 actuates a piston in a master cylinder 10, by means of which a hydraulic fluid is conveyed to a slave cylinder 11, whereby the piston 12 of the slave cylinder 11 actuates the clutch 4 ,
• the clutch actuator 9 is controlled by a control unit 13.
• a not further Darge imputed Kupplungsaktor be electromechanical, in which the electric motor drives ei nen plunger to adjust the clutch.
• Fig. 2 is a simplified representation of the interconnection of the Kupplungsmanagementsys system 1 is shown.
• the control unit 13 included in the clutch actuator 4 is electrically connected to a shift intention sensor 14 disposed on the shift lever 15 of the transmission 16. From the signals of the shift intention sensor 14 and the vehicle electronics 17, which outputs in particular signals for a current driving mode of the vehicle, determines the control unit 13 of the clutch actuator 9, the driver's intention to shift depending on the driving mode ,
• the output signal of the shift intention sensor 14 is compared with a value stored in the control unit 13 threshold value.
• This threshold is different for each driving mode.
• the threshold value can be fixed for each drive mode. Alternatively, however, there is also the possibility that the threshold value is varied as a function of vehicle parameters that change in a predefined driving mode. Thus, as a function of the current driving mode of the vehicle, it is determined by variation of the threshold value when an actual shift intent of the driver is detected by the shift intention sensor.
• a sports mode of the vehicle can be set, in which the threshold value is chosen so that the shift intent is detected early and the driver is thus a very fast switching is possible.
• the threshold is selected so that the shift intent is recognized later, so that the driver can easily put his hand on the shift lever or hold to a certain extent on the shift lever.
