Abstract

PURPOSE: To prevent unrequired speed change, making a change of a speed-change pattern only when a driver wants rapid acceleration seriously, by conducting the change of the speed-change pattern in accordance with the rate of change of an engine load only when the engine load exceeds the fixed value.
CONSTITUTION: In a speed-change decision circuit 2 is inputted an output-signal from a vehicle speed sensor 1 and an engine load sensor 3. The output signal from the load sensor 3 is also sent out to a load-change rate detecting circuit 4, from which a signal corresponding to the speed of change of the engine load is outputted to a switching circuit 5. And, based on a signal from a load comparing circuit 6 which detects a value that the signal of the sensor 3 indicates in correspondence to the load more than the fixed and issues a signal, the above switching circuit 5 is actuated and sends out the signal from the detecting circuit 4 to the speed- change decision circuit 2. In accordance with these three signals, the decision circuit 2 makes a decision on the speed-change position based on the set speed-change pattern, sending out a control signal to a driving circuit 7 for a change-over valve 8 for speed-change.
