    摘要： An electrically-controlled throttle valve apparatus includes a motor, a speed reducing mechanism for reducing rotation speed transmitted from the motor, a throttle valve connected to the speed reducing mechanism, and a force applying device applying force to the throttle valve in the direction of returning the valve to its initial position and adjusting the opening of the throttle valve by driving the motor. Parameters of the motor, the speed reducing mechanism, and the force applying device have values such that the operation time t from the minimum to the maximum throttle valve opening, which is determined by an evaluation equation obtained from equations of throttle valve motion, is less than a prescribed target throttle valve operation time t*. Furthermore, resistance and an induction voltage constant of the motor are determined to satisfy a constraint equation obtained based on Ohm's law.

    摘要： An electrically-controlled throttle valve apparatus includes a motor, a speed reducing mechanism for reducing the rotation speed that is transmitted from the motor, a throttle valve connected to the speed reducing mechanism, and a force applying arrangement for applying force to the throttle valve in the direction of returning the valve to its initial position and for adjusting the opening of the throttle valve by driving the motor. Specification parameters of the motor, the speed reducing mechanism, and the force applying arrangement have values such that the operation time t from the minimum opening to the maximum opening of the throttle valve, which is determined by an evaluation equation obtained from equations of motion of the throttle valve, is less than a prescribed target operation time t* of the throttle valve. Furthermore, the resistance and the induction voltage constant of the motor are determined so as to satisfy a constraint equation obtained based on Ohm's law.

    摘要： There is provided an air flow meter for detecting the flow rate of air, an electronically controlled throttle for opening and closing a throttle valve and a calculating device to which a target engine intake air flow rate, a value detected by the air flow meter, the position of a throttle valve detected by a throttle position sensor, and a value detected by an engine speed sensor are input. The calculating device calculates a time constant of a delay of response of the air flow rate into the engine, and a air flow rate passing through the throttle valve to compensate for the delay of response, and drives the throttle valve such that the flow rate of air passing through the throttle valve agrees with the calculated value.
