Abstract
A method for controlling operation of a throttle valve in an automatic transmission system for automobiles using a microcomputer, including the steps of: (a) detecting an accelerator position, an engine rotational speed, a clutch stroke, a change lever position, an input shaft rotational speed, and a transmission gear position by a transmission gear position sensor; (b) comparing the data determined in step (a) with a predetermined transmission map and a throttle valve operation speed map each stored in a memory of the microcomputer, and calculating the throttle valve operation speed for various driving conditions; and (c) controlling the operation of the throttle valve through a throttle actuator based on a control signal generated from the throttle valve operation speed map. An apparatus for controlling the operation of a throttle valve in an automatic transmission system for automobiles, including a device for detecting operation data for automobiles, a device for comparing the detected data with a predetermined transmission map and a throttle valve operation speed map, a device for determining the throttle valve operation speed based on the compared data, and a device for controlling the operation of a throttle valve based on a control signal generated in accordance with the throttle valve operation speed map.
