Abstract

An apparatus of controlling an intake air throttle valve capable of obtaining the certain drive for the change in the load applied to the throttle valve due to the change in the intake air amount in the transient period, without any increase in current consumption and reduction in responsiveness. The apparatus includes a throttle valve for controlling an intake air amount in the internal combustion engine; a motor for electrically controlling the throttle valve; and a drive circuit for controlling the drive torque of the motor. It further includes a throttle valve opening defining device for defining a parameter indicating the opening of the throttle valve; a comparing device for comparing the value of the parameter defined by the throttle valve opening defining device; and a torque increasing device for increasing the output torque by the drive circuit when the comparing device judges that the value of the parameter is larger than the specified value.
