とする車輌用エンジンの過給圧制御システム。 In a vehicle engine supercharging pressure control system that controls supercharging pressure by opening and closing a waste gate or intake relief gate of a turbocharger, an engine rotation speed detection means for detecting the engine rotation speed, and a waste gate or intake relief gate are provided. In addition to comprising a gate opening/closing means for adjusting opening/closing,
The storage unit has a basic map regarding the reference set boost pressure corresponding to the engine speed and a correction map showing a correction coefficient corresponding to the engine speed increase rate, and also includes the engine speed input from the engine speed detecting means and a correction map indicating the correction coefficient corresponding to the engine speed increase rate. Based on the engine speed increase rate obtained by time processing, a target set boost pressure is calculated from the basic map and the correction map, and the boost pressure of the intake system is adjusted to match the target set boost pressure. It is characterized by comprising a control means for controlling the gate opening/closing means, and the correction coefficient of the correction map is such that the target set boost pressure is lowered from the reference set boost pressure when the engine speed increase rate is equal to or higher than a predetermined value. Boost pressure control system for vehicle engines.
