An ECU executes a program that includes the steps of setting a line pressure to a line pressure ( 1 ) that is appropriate for improving fuel efficiency, if an automatic transmission is not shifting, and a deceleration slip control for a lock-up clutch is not being executed; setting the line pressure to a line pressure ( 2 ) that is equal to or lower than a line pressure ( 3 ) that is appropriate when the automatic transmission is shifting, if it is determined that the automatic transmission is not shifting, and the deceleration slip control is being executed; and setting the line pressure to the line pressure ( 3 ), if it is determined that the automatic transmission is shifting. The line pressure ( 1 ) is lower than the line pressure ( 2 ). The line pressure ( 2 ) is equal to or lower than the line pressure ( 3 ). |
