Abstract

3A method/system for controlling upshifting in an automated mechanical transmission system (10) utilized on a vehicle preferably having an ECU (28) controlled engine brake (ECB) or inertia brake (26). When an upshift from a currently engaged ratio (GR) is required (ES>ES.sub.U/S), skip upshifts (GR.sub.TARGET =GR+N, N>1) and then single upshifts (GR.sub.TARGET =GR+1) are evaluated in sequence.
