ABSTRACT:
A first pump (21) which supplies a required flow amount for speed ratio control and a second pump (22) which supplies a flow amount which is re-cycled to an oil cooler in order to cool the oil are driven at the same time by a common motor (23). A required discharge amount for the first pump (21) is calculated depending on driving conditions and a required discharge amount for the second pump (22) is calculated depending on driving conditions. The motor (23) is controlled to a rotation speed so that a discharge amount is produced which satisfies the larger of the two required pump discharge amounts calculated above. In such a way, pump rotation speeds are controlled so that the required discharge amount is produced depending on driving conditions which enables reductions in electricity consumption and noise.
