When an acquired fuel temperature is higher than a predetermined temperature, the first target fuel pressure defined in the first map is set as a target fuel pressure (steps 1 to 3), and when the fuel temperature is equal to or lower than the predetermined temperature, the second target fuel pressure defined in the second map is set as the target fuel pressure (steps 1, 5, and 6). The fuel pressure is controlled based on the set target fuel pressure (step 7).

Abstract: A sticking condition of a lock-up clutch is judged by an oil temperature of hydraulic oil and a slip ratio of the LC. An intake air amount of an engine is increased while the LC is judged to be in a sticking condition, and the increase of the intake air amount of the engine is terminated when the judgment to be in the sticking condition is canceled. This enables to effectively prevent a rotation speed of the engine from decelerating in a range (timing) where a sticking of the LC occurs, and further prevent the rotation speed of the engine from rapidly accelerating in a range where a sticking of the LC does not occur. Therefore, decelerations of engine rotation speed due to a sticking of the lock-up clutch and rapid accelerations of engine rotation speed after the sticking has been eliminated can both be prevented.
