Abstract
A continuously variable automotive transmission continuously varies the speed ratio between input and output rotational speeds according to an indication of the driver's intention of acceleration or deceleration, an indication of an engine power output, and alternative selection of forward and neutral transmission positions, and also transmits the engine power output to wheels dependent on the operation of a clutch. The operating condition of the clutch is detected and fed back for the control of the transmission in order to perform speed changing operation of the transmission more quickly when the clutch is operated toward a shut-off position upon automobile deceleration than when ordinary speed changing operation is effected by the transmission.
