ABSTRACT:
A supercharger control system for use with an automatic transmission connected to an internal combustion engine and having its gear stages set according to a throttle opening or its corresponding data and an engine R.P.M. or its corresponding data. The range for turning ON the supercharger of the engine is set for each of the gear stages on the basis of the throttle opening or its corresponding data and further to a higher throttle opening side in accordance with the increase in the engine R.P.M. A hysteresis is set such that the range for switching the supercharger from OFF to ON is shifted to a higher throttle opening side than the range for switching the same from ON to OFF. The changing width of the ON-to-OFF range to the higher throttle opening side in accordance with the increase in the engine R.P.M. is set smaller than the hysteresis width within a predetermined gear stage range.
