ABSTRACT:
A shift control system for an automatic transmission of a vehicle includes a steering angle sensor for sensing a steering amount and producing a steering amount signal, a brake sensor for sensing a depression of a brake pedal and producing a brake signal representing the frequency of brake applications, and a control unit for determining a degree of correlation between the steering amount signal and the brake signal, and modifying the shift pattern so as to adapt the shift schedule to driving conditions in narrow streets or the like when the degree of correlation is high.
