Abstract: PURPOSE:To eliminate the need for correcting the delay in detection at a transient time by determining a control value based on an intake pressure obtained from a throttle valve opening at the time of changing speed of a throttle valve above a defined value and an engine speed below a defined value. CONSTITUTION:A throttle sensor 38 detects the opening of a throttle valve 26 provided on the intake air passage 22 of an internal combustion engine 200.
