圧制御装置。 The engine is equipped with a bypass passage connected in parallel to the turbocharger turbine installed in the exhaust passage of the engine body, and equipped with a wastegate valve for adjusting boost pressure that opens and closes this bypass passage. In the supply pressure control device, the waste gate valve is formed by an opening adjustment valve whose opening degree can be adjusted, and is provided with a hill running state detection function for detecting a hill running state of the vehicle. During normal driving other than when driving on a slope where the uphill driving condition is detected by the detection function, the valve opening degree at the time of the opening operation of the waste gate valve is maintained at the normal state, and the slope driving condition detection function The supercharging pressure of the engine is characterized by being provided with a controller that switches and controls the valve opening of the waste gate valve to an increased valve opening state that is increased compared to a normal state when traveling on a slope where a slope running state is detected. Control device.
