An object is to improve fuel consumption efficiency while maintaining a desired driving force. Accordingly, in a case where an assisting possibility of a motor M is increased accompanying a relatively high state of charge SOC of a battery (YES side in step S 02 ), and moreover in a case where a required torque TQAPCC is less than a predetermined value (NO side in step S 03 or YES side in step S 04 ), a "1" is set to a flag value of an LC_ON assistance flag F_LCOAST, and in a region for an accelerator pedal opening AP, and a vehicle speed VP, a region which maintains an LC_ON state where a lock-up clutch 21 is in an engaged state is enlarged compared to for a normal state where the flag value of the LC_ON assistance flag F_LCOAST is "0". In the LC_ON region enlarging state, it is determined whether or not it is possible to shift to the normal state, according to the state of charge SOC and the required torque TQAPCC (step S 07 to step S 09 ).
