Abstract
A control system for continuously varying the transmission gear ratio of a stepless variable speed gear for use in an automobile has a reference driver circuit for delivering a signal indicative of a reference transmission gear ratio to pressure servo controllers according to signals produced by detecting running conditions of the automobile, a deceleration-judging circuit for judging the automobile to decelerate, and a deceleration control circuit for modifying the output signal from the reference driver circuit so as to conform to the transmission gear ratio determined by the speed of the automobile.
