ABSTRACT:
In case information such as an actual gear ratio is not stored in an EEPROM28due to a trouble of a backup power source29or like when an initialization operation of a step motor27is performed at the time of start of a vehicle or during stoppage of the vehicle, an output torque of an engine is limited before the initialization operation. Thereby, even if an accelerator is depressed during the initialization operation of the step motor27in which a sufficient primary pulley pressure cannot be ensured, the output torque of the engine is limited, so that torque inputted to a V-belt type continuously variable transmission is small and slippage does not occurs between the primary pulley and a secondary pulley.
