Patent ID: 6863639

Claim:
A control system for an automatic transmission, comprising: a forward/backward changeover mechanism for switching between a forward mode for causing a vehicle to travel forwards and a reverse mode for causing the vehicle to travel backwards; a detecting device which detects a vehicle speed; a range selector which selects one of a forward range and a reverse range; a detecting device which detects a position of the range selector; a counter which measures a period of time that the range selector has continued to remain at the forward range; and a controller functioning to: make a judgment whether or not the range selector has been switched to a reverse range during forward traveling of the vehicle, make a judgment whether or not the detected vehicle speed is lower than a first vehicle speed and whether or not the period of time that the range selector has remained at the forward range until switching is shorter than a predetermined judgment time when it is determined during forward traveling of the vehicle that the range selector has been switched to the reverse range, and switch the forward/backward changeover mechanism to the reverse mode when it is determined that the detected vehicle speed is lower than the first vehicle speed and that the period of time that the range selector has continued to remain at the forward range until switching is shorter than the predetermined judgment time, and, otherwise, delay the switching of the forward/backward changeover mechanism to the reverse mode.
