ABSTRACT:
In a vehicle equipped with an automatic transmission, the controller of the automatic drive system includes an operation signal generating circuit which outputs a signal that indicates the controller itself being in operation, and the controller of the automatic transmission includes a transmission control releasing circuit which releases the normal transmission control upon receipt of the signal from the operation signal generating circuit. The operation signal generating circuit outputs a signal which indicates that the automatic drive system is in operation, and due to releasing the regular transmission control of the automatic transmission, a shift down of the vehicle speed from the over-drive speed is performed only in such a condition in which the vehicle speed is decreasing in spite of the full opening of the throttle valve.
