<p>PURPOSE:To improve drivability at the time of rapid acceleration and prevent excessive force to an engine and a turbocharger by appropriately adjusting an overshoot quantity of supercharging pressure in the case when the supercharging pressure of the turbocharger fixed to the engine of an automobile, etc., is controlled to the target supercharging pressure. CONSTITUTION:An actuator 8 for opening and closing a waste gate valve 7 of a turbocharger 1 is controlled by an opening/closing control valve 11, and an overshoot quantity of supercharging pressure is detected at the time of rapid acceleration. A controlled timing of the controlled pressure introduced in an actuator 8 is adjusted so as to control the supercharging pressure by varying a judging value of the supercharging pressure at the time of the rapid acceleration based on the detected result.</p> |
