Embodiment Construction

[0019] exist figure 1 A schematic diagram of an electronic clutch management system 1 is shown in , wherein an adaptive clutch 4 is arranged between the engine 2 and the transmission 3 . The transmission 3 is connected to the clutch 4 via a transmission input shaft 5 , and the transmission output is led to the wheels 7 via a transmission output shaft 6 . The clutch 4 is actuated by means of an actuator 9 surrounded by an electric motor 8, which actuates a piston in a master cylinder 10 by means of which hydraulic fluid is supplied to a slave cylinder 11, whose piston 12 is supplied by This operates clutch 4. Here, the control of the actuator 9 is carried out by the control unit 13 .

[0020] like figure 2 The device 14 is shown comprising a control unit 13 which is connected to a selector lever sensor 15 which is arranged opposite a driver-operated selector lever 16 . The selector lever 16 is connected to an internal line 17 of the transmission 3 , which is formed by a se...

Abstract

The invention relates to a method for learning neutral and gears in a manual transmission of a vehicle, the operation of the method being carried out by a clutch system (1) without a clutch pedal, in which a selector lever (1) is detected by a sensor. 16) and the gears of the manual transmission (3), wherein the corresponding gear is shifted by means of the selector lever (16) during learning. In a method that can reliably determine whether the shift lever is not stressed during the learning process, the shift lever sensor ( 15 ) and / or the gear position sensor ( 23 , 24 ) are evaluated over a defined period of time during the shift The position value provided during the process, wherein, when the position value changes relative to a threshold value, it is determined whether the selector lever (16) is free of force.

Description

technical field [0001] The present invention relates to a method for learning neutral and gears in a manual transmission of a vehicle, the operation of the method being carried out by a clutch system without a clutch pedal, in which a sensor detects a shift on a gear lever Intent and gear, wherein the corresponding gear is shifted by means of the selector lever during learning. Background technique [0002] In transmissions with Electronic Clutch Management (EKM), an engine intervention takes place for automatic clutch control. This allows the driver to shift gears via the shift lever without prior reversing torque from the vehicle's driveline by releasing the accelerator pedal. [0003] When an electronic clutch management system without a clutch pedal, which uses sensors to detect the driver's intention to shift gears on the selector lever, learns a gear, the selector lever must not be stressed during the learning process. That is, hands cannot rest on the shift lever. ...
