Verfahren zur Steuerung des Antriebsstranges von Kraftfahrzeugen

摘要

A control is described for the drive train of a motor vehicle with an internal combustion engine, an automatic gearbox, e.g. an automatic mechanical gearbox with electronically controlled mechanical dry clutch, and with an accelerator pedal (13) to which a set value transmitter is assigned, accelerator pedal movement processes being monitored and analyzed with respect to engine power control and gear-shifting processes using a computer (4) and gear-shifting processes being initiated on the basis of stored engine characteristic diagrams and shift characteristic curves and operating parameters which are detected by sensors, and power thresholds (H) being selectively produced on the accelerator pedal travel (S) using the computer (4) and a friction disc; in order to reduce gear-shifting processes, the combustion engine is adjusted correctively with respect to the accelerator pedal position (S) to the engine torque (Mmax) which is the maximum possible one at the respective engine rpm (D), using the computer (4), in each case before a change-down process or a power threshold on the accelerator pedal travel is reached, the torque increase (brought about correctively) along the accelerator pedal travel (S) being brought about continuously up to the respective change-down point or up to the respective power threshold (H).
