METHOD OF AND APPARATUS FOR CONTROLLING THE TRANSMISSION RATIO OF CONTINUOUSLY VARIABLE TRANSMISSION

A speed ratio of a continuously variable transmission is controlled by varying the effective diameters of drive and driven pulleys mounted respectively on input and output shafts with a V-belt trained around the drive and driven pulleys. The effective diameter of the drive pulley is increased based...

Beschreibung
Zusammenfassung:	A speed ratio of a continuously variable transmission is controlled by varying the effective diameters of drive and driven pulleys mounted respectively on input and output shafts with a V-belt trained around the drive and driven pulleys. The effective diameter of the drive pulley is increased based on a signal proportional to a vehicle speed and reduced based on a signal proportional to a throttle valve opening degree and a signal proportional to a speed ratio.
