Abstract
An input torque control system is provided with a primary pulley, a secondary pulley, a V belt wound between these pulleys, a step motor to change a pressure difference between the primary pulley pressure and the secondary pulley pressure to change a gear ratio of the transmission, a memory unit to store pulley information immediately before a vehicle stop, and a torque restricting section. When an initialization operation of the step motor is started without pulley information stored in the memory unit, an output torque of the engine is restricted, and the restriction is removed after the initialization operation is finished.
