ABSTRACT:
A signal from the speed sensor is extracted at a time period which is later than that for detecting a signal from the engine load sensor by a predetermined amount of time. The speed signal thus obtained is used to decide whether or not shifting of the automatic transmission is necessary, so that any incorrect changeover between two or more shift patterns or shifting between two or more of shift positions in a shift pattern is prevented from being selected due to a delay in the response of the vehicle speed relative to the depression of the accelerator pedal.
