This paper presents the development of an autonomous on-road vehicle. First the visual guidance system of a newly developed experimental vehicle is described. Then visual navigation algorithms for human-like lane tracking are proposed and their workability is shown with some actual navigation test results. Finally discussions are made on the feasibility of visual navigation technology.

Owing to the remarkable progress of artificial intelligence technologies, automobile engineers may be able to produce an exciting innovation for the automobile: that is “vehicle autonomy.” It is no longer a dream to build a car which can perceive the outside world and run by itself. A modern automobile goes out of control without proper operations by a human driver. An autonomous vehicle, on the other hand, is a car which is capable of navigating roads and avoiding dangers even without human operation. However, the purpose of vehicle autonomy is not the mere replacement of human labor by machines, but the creation of a new value for the automobile. The objectives of this paper are to discuss how vehicle autonomy technology can be used to benefit car drivers and also to propose a concept of an autonomous highway vehicle which improves highway driving safety.
