Control circuit for continuously variable drive transmission for automobile, provides control signal for transmission ratio dependent on required velocity calculated from monitored operating parameters

摘要

The control circuit provides a control signal (I) for controlling a primary valve (15) determining the transmission ratio of the continuously variable drive transmission, in dependence on a required velocity value, obtained from monitored operating parameters of the automobile supplied to the control circuit. An Independent claim for a method for providing a control signal for a continuously variable drive transmission is also included
