Method of disengaging positively closure clutch e.g. claw clutch in motor vehicle drive train, involves estimating clutch torque on closure clutch so that closure clutch is disengaged, only if estimated torque is below limit value

摘要

The front axle (12) and rear axle (13) of the motor vehicle drive train (11) are positively interconnected by a closure clutch (10) in one of operating modes. The clutch torque on closure clutch is estimated. The closure clutch is positively disengaged in a normal operation, only if an estimated torque is below a limit value based on a steering angle signal. An independent claim is included for motor car device.
