PURPOSE:To prevent hunting of a speed change control operation due to minute fluctuation in speed control information by controlling a stepless speed change gear to change the speed only when the change amount of speed change control information is above a designated set value. CONSTITUTION:In case of controlling a stepless speed change gear T to change speed, it is judged whether the change amount DELTATC of speed change control information is above a designated set value alpha or not. If DELTATC<alpha, the stepless speed change gear is not controlled, and only when DELTATC>=alpha, the stepless speed change gear T is controlled to change the speed according to speed change control information, so that hunting due to minute fluctuation in speed change control information can be prevented. |
