Motorfordon med växellåda och förfarande för drivning av ett motorfordon

摘要

In a motor vehicle transmission, gears representing different transmission ratios are engaged by applying a force to an actuator output element that couples a selected gear to a rotary shaft. A synchronizing device blocks the coupling of the gear to the shaft until at least an approximate synchronization of rpm-rates has been achieved. A synchronization threshold position corresponding to the blocked condition of the actuator element is stored in a memory of a controller device. The controller device periodically performs an automatic adaptation of the stored value for the synchronization threshold position.
