Abstract
A control apparatus for a vehicle equipped with continuously-variable transmission includes a drive source; a continuously-variable transmitting mechanism including a primary pulley, a secondary pulley and a power transferring member; a friction engagement element provided between the drive source and the continuously-variable transmitting mechanism; and a vehicle-stop LOW shift control section including a vehicle-stop judging section configured to judge if the vehicle is in a stopped state. A power-transferring state of the friction engagement element is controlled by an engaging-force control. The vehicle-stop LOW shift control section starts a vehicle-stop LOW shift control to shift a pulley ratio of the continuously-variable transmitting mechanism toward LOW side when the vehicle-stop judging section determines that the vehicle is stopped under a power-transferring state where the friction engagement element is in an engaged state and the pulley ratio is not in a LOWEST region.
