PURPOSE:To enable stable control by providing a control means for carrying out feedback control based on a deviation of transmission gear ratio when the deviation is large, while carrying out the feedback control based on the deviation of input revolution speed when the deviation is small. CONSTITUTION:When a deviation of a target value and an actual value (devia tion of target input revolution speed and actual input revolution speed, or devia tion of target transmission gear ratio and actual transmission gear ratio) is large, feedback control is carried out based on the deviation of the target trans mission gear ratio and the actual transmission gear ratio. Thus, even when the input revolution speed is small, as the deviation of the transmission gear ratio becomes large and an amount of feedback to add becomes large, a motion amount of a step motor becomes large so that transmission response can be improved. In the meantime, when the deviation of the target value and the actual value is small, feedback control is carried out based on the deviation of the target input revolution speed and the actual input revolution speed. |
