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 an engine 2 and a transmission 3 . The transmission 3 is connected to the clutch 4 via a transmission input shaft 5 , while the transmission output is led to the wheels 7 via a transmission output shaft 6 . The operation of the clutch 4 takes place via an actuator 9 surrounded by an electric motor 8, wherein the electric motor 8 operates a piston in the master cylinder 10, by means of which hydraulic fluid is conveyed to the slave cylinder 11, the piston 12 of which is driven by the This operates clutch 4. In this case, actuator 9 is controlled via control unit 13 .

[0020] Such as figure 2 As shown, device 14 comprises a control unit 13 , which is connected to a selector lever sensor 15 which is arranged opposite a selector lever 16 actuated by the driver. The selector lever 16 is connected to an internal circuit 17 of the ...

Abstract

The invention relates to a method for learning neutral / gear positions of a manual transmission of a vehicle, said transmission being actuated by a clutch pedal-free clutch system (1), wherein a shiftintent on a shift lever (16) and the gear positions of the manual transmission (3) are detected by sensors, and each gear is shifted by means of the shift lever (16) during the learning process. In amethod in which the absence of a force on the shift lever can be reliably inferred during the learning process, the position values supplied by the shift lever sensor (15) and / or the gear position sensor (23, 24) during the shifting process are evaluated over a specified duration, and in the event of a change in the position values relative to a threshold, it is inferred whether the shift lever (16) is free of a force or not.

Description

technical field [0001] The invention relates to a method for learning a neutral / gear position in a manual transmission of a vehicle, the operation of which is carried out by means of a clutch system without a clutch pedal, in which a shift on the gear lever is detected by a sensor Intent and gear, wherein during learning, the corresponding gear is shifted by means of the selector lever. Background technique [0002] In transmissions with Electronic Clutch Management (EKM), an engine intervention is performed for automatic clutch control. This allows the driver to change gears via the gear selector without previously having to undo torque from the vehicle's driveline by releasing the accelerator pedal. [0003] In the case of an electronic clutch management system without a clutch pedal, which uses a sensor to detect the driver's shifting intention on the selector lever, to learn the gears, the selector lever must be free of force during the learning process. That is, hands...
