Abstract
A shift control apparatus for use in an automotive vehicle including an engine, an automatic transmission, and an engine accelerator operable to change the amount of air permitted to enter the engine. The apparatus monitors the speed of operation of the accelerator and repetitively samples the accelerator operation speed to accumulate the last accelerator operation speed values for a short period of time so as to form a first frequency distribution of the accelerator operation speed values and accumulate the last accelerator operation speed values for a long period of time so as to form a second frequency distribution of the accelerator operation speed values. The first frequency distribution corresponds to a driver's present vehicle driving inclination and the second frequency distribution corresponds to a driver's normal vehicle driving inclination. A deviation of the first frequency distribution from the second frequency distribution is detected and used to select one of a plurality of shift schedules. A shift change is produced in the automatic transmission according to the selected shift schedule.
