<p>A vehicle control device which performs speed change control on an automatic transmission (4), making use of road information stored in a navigation system equipment. The vehicle control device inhibits unnecessary shift-up and can perform gear ratio control in line with a driver's intention by setting an upper limit on a gear ratio so as to limit a possible range of the gear ratio in accordance with road information stored in a data storage unit (12), allowing a change in the gear ratio within the limited range, effecting shift down with starting of a driver's slowdown operation, for example, accelerator off, as an opportunity, and setting an upper limit value depending upon running environments. <IMAGE></p> |
