Abstract:
A method for controlling a drivetrain including an automatically shifted starting clutch and gear-shift clutch and a transmission, with a non self-locking clutch actuator, a gear actuator for engaging and disengaging transmission gears and a control unit which generates control commands for the clutch actuator and gear actuator and transmits such commands to the actuators such that, when the vehicle is at rest and a gear is engaged and if the clutch actuator fails, the clutch does not inadvertently engage. When a transmission gear is engaged, a control command is generated and sent for the clutch actuator to disengage the clutch. Thereafter, the vehicle speed is determined and if the speed is essentially zero and the clutch begins to engage, a control command is sent to the gear actuator to shift the transmission to its neutral position.
