Drivaggregat för motorfordon

摘要

Drive means for motor vehicles, comprising an internal combustion engine (1) and an unsynchronised automated multi-stage 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. At least one auxiliary unit (61) is engagable to and disengagable from a power takeoff (62) with the aid of manual and/or automatic switch means (63). An override function can be programmed into the transmission control unit so that the transmission control unit takes over the control of the auxiliary unit at the beginning of shifting and returns control of the auxiliary unit to the switch means after completed shifting.
