PURPOSE:To prevent shift-up in an automatic transmission, by shifting a speed change point in the automatic transmission to a higher speed side according to turning of a vehicle. CONSTITUTION:During turning of a vehicle, an output voltage VG from a sensor 6 is greater than a reference voltage VGref, and a comparator 5 supplies a H level signal to a base of a transistor 3. At this time, a down-shift solenoid 1 is energized by a power supply +V to switch a speed change point from a partial region to a kickdown region and shift the same to a higher speed side. Accordingly, the automatic transmission keeps the same transmission range as before turning of the vehicle. |
