ABSTRACT:
An engine (4) of a drive system (2) is adjusted and controlled by a main controller (24). When the main controller (24) breaks down, the operation of the engine can still be continued as emergency operation with an emergency controller (26). However, the controlling functions of the latter are not as optimum as those of the main controller (24). This functional deficiency of the emergency controller (26) is compensated for at least partly by an emergency program of an electronic transmission control device (28). To compensate for the functional deficiency of the emergency controller (26), the transmission control device (28) appropriately controls or regulates a transmission unit (6, 8, 10) of the drive system (2), which comprises a hydrodynamic torque converter (8) with a bridging clutch (10) that can bridge the latter, and a gear-shift mechanism (6).
