Abstract

PURPOSE:To improve the acceleration performance and acceleration feeling and obtain the simple constitution by automatically changing the speed change point to the high speed side until a specific condition is satisfied, when the throttle opening degree less than a prescribed value continues for a prescribed time. CONSTITUTION:A control unit 4 operates a shift solenoid 6 according to the signal state supplied from a throttle sensor 2 for detecting the opening degree of a throttle valve and controls the operation of a hydraulic controller 8. When the throttle valve is held in a low opening degree for a prescribed time, a speed change point map is changed to a power map from a common speed change map until a prescribed time lapses from the time when the speed change point is changed or until the throttle opening degree becomes over a prescribed value. When the throttle opening degree less than a prescribed value does not continue for a prescribed time, the common speed change map is used. Therefore, the acceleration performance and acceleration feeling can be improved, and the simple constitution can be obtained by reducing the number of parts.
