A continuously variable transmission of an automobile which varies the drive ratio arbitrarily between an input axis and an output axis is combined with a traction control device for example which performs braking corresponding to vehicle running conditions and irrespective of the accelerator pedal depression. A microprocessor calculates the vehicle speed from the rotation speed of the output axis, calculates the target drive ratio depending on the vehicle speed, and controls the drive ratio of the continuously variable transmission to be equal to the target ratio. When the brake operation device performs braking, fluctuation of the drive ratio based on the rotation variation of the output axis is prevented by the correction of the drive ratio in the upshift direction.
