ABSTRACT:
A change ratio control apparatus is arranged to set the lower limit of the change ratio to values included in a range in which transmission efficiency does not deteriorate due to the reduction in the change ratio if the transmission efficiency of the driving force in the transmission deteriorates in a low load region in which the change ratio is low. Therefore, deterioration in the transmission efficiency can be prevented and the fuel consumption rate can thereby be improved.
