Abstract
A vehicle driving control system and method which enables the vehicle can travel through each curve at the optimum speed on an ordinary road and also on a highway. The controller and method uses a car navigation system to detect road classification about the road ahead of where the vehicle is running under guidance. When the road is an ordinary road, the following with respect to the preceding vehicle is given priority; when the road is a highway, the target vehicle speed obtained from the navigation information of car navigation system and the vehicle speed in the following mode are compared with each other, and the lower vehicle speed is selected (select-low) under control. As a result, it is possible to travel through the curves at a reliable speed not only on ordinary roads, but also on highways.
