Abstract

Drive means for motor vehicles, comprising an internal combustion engine (1) and an unsynchronised automated stepped gearbox (9). The clutch and the gearbox are controlled by an electronic transmission control unit (45), which communicates with an engine control unit (48), to which are fed signals representing the selected gear from a gear selector (46) and signals representing various engine and vehicle data. The input shaft (7) to the gearbox is coordinated with a torque sensor (60), which sends a signal corresponding to the input shaft torque to the transmission control unit, which is disposed to initiate shifting only when the torque sensor indicates that the torque on the input shaft is zero or at least practically zero.
