ABSTRACT:
A vehicle engine throttle valve control apparatus whereby the actuation position of an accelerator pedal, the degree of opening of the throttle valve, and the position of the vehicle gear shift are detected. One of a plurality of different throttle valve target opening degree characteristics is then selected which corresponds to the current gear shift position, and the selected characteristic is used to set a target degree of opening for the throttle valve in accordance with the accelerator pedal position. The throttle valve is driven so as to make the actual degree of throttle opening become equal to the target value. Appropriate throttle control is thereby automatically performed each time a gear shift operation is executed, without intervention by the vehicle driver.
