Patent ID: 8366588

Claim:
A method for controlling a drivetrain having an automatically shifted starting and gear-shift clutch ( 43 ), an automatic transmission ( 46 ), a clutch actuator ( 4 ) which, in relation to an actuation movement, is not made self-locking, a gear actuator ( 8 ) for engaging and disengaging transmission gears, and a control unit ( 31 ) which, with information received from sensors and control programs, generates control commands for the clutch actuator ( 4 ) and the gear actuator ( 8 ) and transmits the control commands to the clutch actuator ( 4 ) and the gear actuator ( 8 ), the method comprising the steps of: generating a first control command when a transmission gear is engaged; sending the first control command to at least one activation mechanism ( 14 ) for the clutch actuator ( 4 ) to disengage the gear-shift clutch ( 43 ); determining a speed of the vehicle; if the speed of the vehicle is substantially zero and a start of undesired engagement of the gear-shift clutch ( 43 ) is detected, generating a second control command; and sending the second control command to at least one actuation mechanism ( 17 , 18 ) of the gear actuator ( 8 ) to shift the transmission ( 46 ) to a neutral position.
