Title:
INTERNAL COMBUSTION ENGINE SYSTEM AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/004108
Kind Code:
A1
Abstract:
An internal combustion engine system and a vehicle capable of preventing excessive rotation of a compressor are provided with: a compressor that is disposed in an intake path and rotates so as to pressurize air sucked in an internal combustion engine from the intake path; a sensor that detects a supercharging pressure that is a pressure of air sucked in the internal combustion engine; and a control unit that performs feedback control of a supercharging pressure on the basis of a difference between a target value of a supercharging pressure corresponding to an operating state of the internal combustion engine and a detection value of the sensor. When a state in which a difference does not fall within a prescribed value continues over a prescribed time, the control unit further controls a supercharging pressure on the basis of a feedforward amount set in advance.
