A speed change control system configured to allow a driver to promptly sense a response to an accelerating operation. A reference index value that the driver senses an acceleration response is calculated based on acceleration of a vehicle. If the reference index value is smaller than a first reference index value at which the driver is allowed to sense the acceleration response, a downshift point is lowered to a first drive force.
