<p>PURPOSE:To prevent an engine from knocking, by correcting a reference transmission (CVT) ratio signal to the transmission ratio found out a car speed on the basis of a signal of a deceleration judging device out of an accelerator signal and a transmission ratio and a car speed signal. CONSTITUTION:There are provided with a reference driving circuit 600 outputting a reference transmission ratio signal (CVT) to a driving device of a stepless transmission, a deceleration judging device 700 judging deceleration from an accelerator signal in running and a CVT signal and a decelerating control circuit 750 receiving a car speed signal and correcting an output signal out of the reference driving circuit 600 to the transmission ratio found out of a car speed. Therefore, even if an accelerator pedal is made to come off, the CVT ratio is heightened enough so that an engine never causes knocking and is shiftable to clutch disengagement in a smooth manner.</p> |
