ABSTRACT:
A shift characteristic of an automatic transmission is altered in accordance with a load of an engine and a change rate the load of the engine. The shift characteristic may have a power mode and an economy mode, and the shift characteristic is switched between the power mode and the economy mode when the load of the engine becomes a predetermined reference value. When the load of the engine becomes equal to or larger than the reference value, the economy mode is shifted to the power mode. The reference value is changed in accordance with a change rate of the load of the engine, and the reference value becomes smaller as the change rate becomes larger. This construction allows the shift characteristic of the automatic transmission to be altered so as to be appropriate for the requirment by the operation for acceleration.
