A speed-change pattern switching control system for an automatic transmission of a motor vehicle which can ensure enhanced comfort when driving the motor vehicle. The system decides the running state of the motor vehicle on the basis of driving/operation information (Te, Tm, Talpha, alphaf, alphas), performs a first filter processing on the running state information and the driving/operation information (Vs, theta, alphaf, Ws, Ps), stores the manipulated information (Jm) for the motor vehicle in the manual speed change mode, performs a second filter processing on the manipulation information (Jm) in the manual speed change mode, outputs of the running state and the driving/operation information, and corrects speed-change patterns for the automatic transmission on the basis of output signals of the first and second filter processing. The correction is designed to correct the speed-change pattern for the automatic transmission so that the output of the second filter processing can be reflected in the correction of the speed-change pattern upon changeover to the automatic speed change mode from the manual speed change mode. |
