Gear change control method for automatic gearbox unit, involves aligning target gear unilaterally with large speed gradient at beginning and with small speed gradients to coupling at end of synchronization

摘要

The method involves controlling an electric machine for synchronization of the target gear in such a manner, that the output speed of the coupling of the target gear is unilaterally aligned, with large speed gradient at the beginning and with small speed gradients to the coupling at the end of the synchronization, in asymptotic manner to the output speed of the coupling.
