Title:
THROTTLE VALVE CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2018/221160
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a novel throttle valve control device for an internal combustion engine, with which the target torque of the internal combustion engine can be accurately generated. To achieve this purpose, the the present invention comprises a target intake new air quantity calculator 41 that calculates target intake new air that will pass through a throttle valve, an EGR gas flow rate calculator 43 that calculates an estimated flow rate of EGR gas that will pass through the throttle valve, a target intake gas rate calculator 44 that calculates a target intake flow rate for gas that will pass through the throttle valve on the basis of the target intake new air flow rate and the estimated EGR flow rate, and a target throttle valve opening degree calculator 45 that calculates a target opening degree for the throttle valve from the target intake gas flow rate. A target torque can be accurately generated because the target throttle opening degree is set on the basis of the target intake new air flow rate and the throttle-passing flow rate for EGR gas passing through the throttle valve.
