Abstract:
A control system for controlling switching of speed-change patterns for an automatic transmission of a motor vehicle, comprising:various types of sensors for detecting driving states of the motor vehicle on which an automatic transmission is installed and operation states of said automatic transmission as driving/operation information;running state decision means for deciding the running state of said motor vehicle on the basis of said driving/operation information;first filter means for performing a filter processing on said running state information and said driving/operation information;manipulation information storage means for storing manipulation information for said motor vehicle in a manual speed change mode;second filter means for performing a filter processing on said manipulation information in said manual speed change mode, outputs of said running state decision means and said driving/operation information; andcorrecting means for correcting speed-change patterns for said automatic transmission on the basis of output signals of said first and second filter means,wherein said correcting means is so designed as to correct a speed-change pattern for said automatic transmission on the basis of the output signal of said first filter means in the automatic speed change mode of said motor vehicle,while updating the output signal of said second filter means in the manual speed change mode,and upon changeover from said manual speed change mode to said automatic speed change mode of said motor vehicle, said speed-change pattern is corrected such that the output signal of said second filter means can be reflected in said speed-change pattern.
