A transmission controller for a continuously variable transmission system steadily returns a gear ratio toward the low-ratio range during deceleration, even in a hybrid vehicle which stops an engine during deceleration. A control unit determines the return-start number of revolutions of a driving pulley and the duty ratio of an actuator and issues a control instruction to the actuator which changes the gear ratio by varying the groove width of the driving pulley. The control instruction is issued after an engine stop instruction from a drive control element and the return-start number of revolutions is set higher as the gear ratio is closer to the top-ratio range.
A transmission controller for a continuously variable transmission system of a vehicle having an engine that includes a crankshaft and having a driving wheel, the transmission system including a motor, a driving pulley disposed on a side of the motor, a driven pulley for transmitting power to the driving wheel via a free wheeling clutch, a belt wound between said driving pulley and said driven pulley, a start-up clutch connected between said crankshaft of said engine and said driving pulley to transmit power from said crankshaft to said driving pulley when said crankshaft equals or exceeds a specified number of rotations, and gear ratio control means for changing a gear ratio by varying a groove width of said driving pulley, said transmission controller comprising:
