In order to prevent belt slippage induced by overly rapid depressurization of a chamber forming part of a continuously variable transmission V-belt pulley control arrangement, and simultaneously endow the transmission with good response characteristics, the difference between a value indicative of the desired gear radio (e.g., the desired gear ratio per se or the desired engine speed) and one indicative of the actual gear ratio, is produced, differentiated and added to itself. The maximum value of the addition is limited (by slicing or the like) and the result used to control the hydraulic pressure prevailing in the aforementioned chamber. |
