Abstract
A vehicle control device controls an automatic transmission by utilizing road information stored in a navigation system unit. In response to the road information stored in a data memory, the upper-limit of a shiftable transmission speed range is determined, thereby allowing shift-change only within the restricted transmission range. The actual down-shift is carried out after confirming a decelerating operation by the driver, such as release of the accelerator pedal, thereby providing favorable transmission control in conformity with the driver's intention.
