<p>A oil supply system (58s) is provided for the CVT (46) of an automobile, and includes: a variable-transmission hydraulic controller, which employs hydraulic oil to adjust the actual gear ratio until the actual and the target gear ratios match; and a CVT controller (49), which transmits operation instructions to the variable-transmission hydraulic controller. The variable-transmission hydraulic controller includes a motor-driven oil pump (2), driven by an electric motor, for supplying hydraulic oil to the CVT. Based on an operation instruction transmitted by the CVT controller, the electric motor (3) is rotated either forward to increase the pressure of hydraulic oil to be supplied to the CVT, or rearward to reduce the pressure, so that the pressure of the hydraulic oil can be adjusted to obtain a required pressure value that is consonant with the operating state of the automobile.</p> |
