  • Supercharging pressure control method for internal combustion engines
    Patent number: 4970864
    Abstract: A method of controlling supercharging pressure in an internal combustion engine wherein the supercharging pressure created by a supercharger is controlled based on a basic control amount determined in dependance on operating conditions of the engine. The basic control amount is corrected in response to the difference between an actual value of the supercharging pressure and a desired value thereof when the engine is in a feedback control region. The basic control amount is corrected in accordance with the rate of change of the supercharging pressure when the engine is in an operating condition immediately before the feedback control region. The supercharging pressure is controlled based upon a second basic control amount other than the first-mentioned basic control amount when the supercharging pressure is below a predetermined value determined by the engine rotational speed and the rate of change of supercharging pressure in the above operating condition.
