SYSTEME ET PROCEDE DE COMMANDE D'UNE BOITE DE VITESSES ET MOYENS ELECTRONIQUES D'ANALYSE MIS EN OEUVRE DANS CE SYSTEME

摘要

The motor vehicle gearbox (4) shift control has sensors (20,24,26) for vehicle operating parameters and a computer (12) to analyze the parameter data. The computer analyses driver gear shift input to determine a shift movement accuracy in regard to the operating conditions and select an optimum ratio. The computer establishes a correction parameter between the actual and required transmission shift and corrects downshift movement.
