Abstract

Drive unit for motor vehicles, comprising an internal combustion engine (1) and a unsynchronised stepped automated gearbox (9) connected to the engine via a clutch (3). The clutch and the gearbox are controlled by an electronic control unit (45), which communicates with an engine control unit (48) to which there are fed signals representing the selected gear from a gear selector (46) and signals representing various engine and vehicle data. The engine control unit is disposed, when the synchronization with the engine when shifting demands a lower engine speed than the engine idle speed determined by the engine control unit for the selected gear, to steer the engine speed to a lower rpm than idle rpm. The transmission control unit is disposed to engage the selected gear when the engine speed has reached a speed lower than idle speed, which is suitable for engaging the selected gear.
