Shift control apparatus for shifting up transmission upon re-acceleration following deceleration of vehicle |
摘要 |
A shift control apparatus for an automatic transmission of a motor vehicle is disclosed. The shift control apparatus includes a shift control device for automatically shifting the transmission according to a predetermined shift control pattern, on the basis of a speed of the engine and a currently required output of the engine. When a vehicle driver operates to re-accelerate the vehicle after deceleration with the transmission shifted down to the low-speed gear position, the transmission is shifted up from the lower-speed gear position to the high-speed gear position having the smaller speed reduction ratio than the lower-speed gear position, if a predetermined period of time has not elapsed after the low-speed gear position is established. Also disclosed is a shift control apparatus including the same shift control device, wherein the engine idling speed is raised from a normal level up to an elevated level when an additional load is applied to the engine, and wherein a shift-down point of the engine speed in the shift control pattern is shifted, in response to a rise in the idling speed to the elevated level, from a first point corresponding the normal level of the idling speed up to a second point corresponding to the elevated level.
