CONTROL SYSTEM FOR BELT TYPE CONTINUOUSLY VARIABLE TRANSMISSION

摘要

A control system for a belt-type continuously variable transmission capable of preventing deterioration in fuel economy. A friction coefficient mu2 in a radially outer region of the tapered face of the driven pulley 7 is smaller than a friction coefficient mu1 in a radially inner region, and the control system comprises a speed change region setting means that increases frequency of carrying out a speed change operation within the radially inner region in case the energy saving mode is selected.
