Abstract:
A transmission control system for controlling an automatic transmission when a new transmission shift request occurs while a prior gear-shifting operation is still being performed, comprising:a shift lever whose position is changeable through a lever-shifting action by a driver selecting a transmission stage to be changed into; a transmission stage detection unit for detecting a new position of the shift lever due to the lever-shifting action and outputting corresponding signals; and a transmission control unit receiving the signals from the transmission stage detection unit and performing a gear-shifting operation of the transmission, the transmission control unit having therein a time map of a number of values of permissible time intervals that respectively correspond to all kinds of gear-shifting operations of the transmission, and when the new transmission shift request is input to the transmission control unit currently performing a prior foregoing gear-shifting operation, the transmission control unit allows the prior gear-shifting operation to be held only during a corresponding permissible time interval set in the time map and then performs the newly requested gear-shifting operation.
