Abstract

When a load to an engine of a vehicle running at a constant speed increases and a vehicle speed slows down below a preset vehicle speed for a constant speed running condition, a gear of an automatic transmission is shifted down. A shift-down signal for causing the gear to shift down is held for a predetermined time to prevent the shift-up of the gear in cases when the vehicle speed momentarily recovers the preset vehicle speed.
