PURPOSE:To prevent electrical noises from being accumulated, by securely resetting a speed change ratio command signal into a state corresponding to a predetermined rotational position of a speed change motor when the motor reaches the predetermined rotational position. CONSTITUTION:After assembling each V-belt type stepless speed change gear, the number of pulses the rotation by which amount from a maximum speed change ratio position (pulse number=0) is required for a speed change reference switch to be turned ON is tested, and the pulse number NA* thus obtained is stored at a predetermined address in a ROM. Consequently, an actual pulse number NA at the moment the speed change reference switch is turned ON and the pulse number NA* for resetting correspond accurately to rotational positions of a step-motor which is an actual speed change motor. Accordingly, the actual pulse number NA is corrected to an accurate value every time the reference switch is turned ON, so that errors can not be accumulated. |
