PROBLEM TO BE SOLVED: To improve a performance, reduce costs, and form this device in a compact size by providing with a correction control means for correcting a signal from an input flow rate detecting means and controlling throttle means. SOLUTION: An air flow rate signal 113a is corrected from, for example, a throttle valve, an air flow rate value, and a map and the like of a flow rate detecting error under its assembling condition by a throttle valve opening signal 116, and an air flow rate signal 113b after correction is outputted to an ECU as an air flow rate signal detected by an electrically controlled throttle body integrated type flow rate meter. A normal throttle valve opening is mainly controlled by an acceleration opening signal 115, and it is necessitated that the throttle valve opening is controlled for controlling a best air flow rate at the time of idling, for reducing a torque shock generated when an acceleration is rapidly changed, and for controlling the air flow rate matched with a rate for supplying fuel to an engine. And a motor control signal 111 as a control rate of an electrically controlled throttle motor is decided on the basis of the corrected air flow rate signal 113b. It is thus possible to control the throttle opening in the electrically controlled throttle body integrated type air flow rate meter. |
