A shift control device for an automatic transmission is disclosed. The device comprises a vehicle speed sensor for sensing vehicle speed, an engine load sensor for sensing engine load, a shift control circuit for generating shift instruction signal based on a predetermined shift pattern in accordance with output signals from both sensors, a shift pattern decision circuit including means for generating a resulting signal obtained by arithmetically operating upon the actually measured acceleration from the output voltage of the vehicle speed sensor, a reference acceleration setting means connected to both sensors for obtaining for every shift position a reference acceleration corresponding to the output signals delivered from the vehicle speed sensor and engine load sensor, a comparator means for comparing the actually measured acceleration with the reference acceleration to change a predetermined shift pattern based on the compared result, and means for setting a hysteresis characteristic to the change of the shift pattern. |
