摘要

An intake throttle valve control apparatus for an internal combustion engine (11) with EGR control is provided with an EGR valve (42) for returning exhaust gas to the internal combustion engine (11) and an intake throttle valve (14) disposed in an intake passage (16) so that the intake throttle valve control apparatus can perform cooperative control of the intake throttle valve (14) and the EGR valve (42). The intake throttle valve control apparatus adjusts an amount of exhaust gas recirculation to a desired value by performing cooperative control so as to adjust opening degrees of the EGR valve (42) and the intake throttle valve (14) to respective desired values in accordance with an operating state of the internal combustion engine (11). When one of the intake throttle valve (14) and the EGR valve (42) assumes an actual opening degree different from a desired opening degree by a predetermined value or more, the intake throttle valve control apparatus performs correction control such that the other of the intake throttle valve (14) and the EGR valve (42) assumes an opening degree different from a desired opening degree corresponding to an operating state of the internal combustion engine (11).
