Application of the AI Technique to a CAD System for Automobiles

An expert system has been developed for use in designing exhaust tube layout. Featuring artificial intelligence (AI) techniques, this system is included in our CAD system. It provides designers with information for detecting and correcting design mistakes, based on a body of rules consisting of design standards and accumulated know-how. As a result, it shortens design time and reduces errors. This system is also useful for standardizing design procedures and transmitting techniques accurately. This paper describes the new system and application to exhaust tube layout design.

It discusses various problems that must be solved in applying AI techniques to the automobile design process as well as areas and methods of application.
