GANGWECHSELVERFAHREN FÜR EINE AUTOMATISIERTE SCHALTGETRIEBEEINHEIT UND AUTOMATISIERTES GETRIEBE FÜR EIN FAHRZEUG

摘要

The present invention relates to a shift change process for an automated manual transmission unit of a vehicle, said transmission including a friction clutch and a dog-clutch type transmission, said shift change process comprising a gear change assist control adjusting the engagement condition of the clutch, in that the clutch is connected at a first speed (speed A), and upon reaching a reference clutch position, the clutch is further connected at a second speed (speed B) lower that the first speed to establish a dog-contact condition to apply a rotational driving force to a follower side of a friction clutch so that a first gear and a second gear of a dog-clutch-type transmission can rotate relative to each other.
