するスロツトル弁制御装置。 A throttle valve is provided downstream of the surge tank and is driven by motors A and B, which are arranged for each bulk. If either of the motors A or B fails, the throttle valve of the failed motor is The opening degree Θ of the throttle valve is detected, and based on this opening degree Θ and the engine speed NE, the intake air amount Ga on the fail side is determined.
A, and subtracts the fail-side intake air amount GaA from the total intake air amount Ga detected by the air flow sensor to obtain the normal-side intake air amount GaB. Throttle valve control device.
