ABSTRACT:
A control unit 11b which consists of a microcomputer compensates the detected intake manifold pressure Pb with an atmospheric pressure, obtains a first estimated position of the throttle when the amount of by-pass air is null and a second estimated position of the throttle when the mount of by-pass air is the maximum from the intake manifold pressure compensated with the atmospheric pressure and the detected revolution speed Ne, obtains the ratio of the amount of by-pass air currently under control to the maximum controllable amount of by-pass air, estimates the position of the throttle from the ratio and the first and second estimated positions of the throttle, and collates the estimated position of the throttle after compensation and the detected vehicle speed V.sub.s with the speed change map to shift the gear of the automatic transmission 3. This provides a feeling of smooth ride by eliminating use of the throttle position detection means and the step of learning the completely closed position of the throttle valve.
