Controling automated gearbox involves determining load on synchronizing device during synchronization and applying safety measures if defined load limit exceeded

摘要

The method involves detecting the start and end of synchronization, determining the load on the synchronizing device and applying safety measures if a defined load limit is exceeded. A differential revolution rate gradient in the synchronizing device and a displacement gradient in the actuation drive are determined; the start of synchronization is detected when the first gradient exceeds a defined value and the displacement gradient is null.
