PROBLEM TO BE SOLVED: To utilize the tough feeling of a supercharger by providing a boost pressure sensor for detecting the boost pressure of a supercharger, detecting the boost pressure and the rotation up ratio of an engine, and lock-up controlling a lock-up clutch when the engine rotation tends to rise in full-boost state. SOLUTION: A boost pressure sensor 9 for detecting the boost pressure is provided within an intake pipe 5, and the boost pressure signal detected by the boost pressure sensor 9 is inputted to a controller 8 through a circuit 10. In the controller 8, a lock-up clutch 7 is immediately locked up regardless of the rotating speed of an engine, predicting the lock-up state, when the operation of the accelerator by a driver is continued, the boost pressure is in full-boost state, and the engine rotation tends to rise. Accordingly, the tough feeling peculiar to the supercharger in which the engine exhibits the full-boost torque while toughing it out and races up itself can be exhibited. |
