Steuerung für ein hilfskraftbetätigtes Schaltgetriebe

摘要

A control system for a servo-assisted automatic gearbox (AS) in which the gearbox control unit (CA) communicates by means of a data line (LD) with the engine management unit (CM) in such a way as to optimise the gear-change operation. In particular, the gearbox control unit (CA) transmits to the engine management unit (CM), during the course of the various phases A, B, C, D, E of the gear-change operation, the target speed of rotation or desired torque and receives instantaneous information relating to the speed of rotation and delivered torque so as to be able to perform the clutch engaging and disengaging operations and the gear engaging and disengaging operations in an optimal manner. $$
