PROBLEM TO BE SOLVED: To provide a shifting shock load reduced control function in a step gear shifting mode in a step less transmission having an automatic gear shifting mode and the step gear shifting mode. SOLUTION: In the step less transmission having the automatic gear shifting mode and the step gear shifting mode, the transmission provides a shifting shock load reduced control unit in the step gear shifting mode. The control unit can start a timer count at the step S.2 if the down gear shifting is executed in the step gear shifting mode at the step S.1 and it is characterized in that the control unit compares the magnitude of the deceleration G with the predetermined limit at the step S.4 during alteration of the gear ratio by control motor and reduces the shock load at the step S.5 minimizing the deceleration G by stopping the electric current to the control motor for ultra short time when the magnitude of the deceleration G exceeds the predetermined limit. |
