The design of vehicles is heavily constrained by legislation and standards. The design of the passenger compartment presents particular challenges due to the variation and uncertainty connected with human activity. Computer aided design systems that address the ergonomic problems are available, but do not generally support the application of knowledge such as standards and legislation. This paper describes the combination of two aspects of the problem (a geometric model of the product and a knowledge base related to performance requirements) in the field of interior packaging of cars. The geometric modelling system handles the spatial aspects and supplies information to an appropriate expert system. The expert system evaluates proposed designs and sends suggestions for improvements back to the design system. The KES expert system and the .SAMMIE computer aided ergonomics design system have been combined to investigate aspects of reach to controls, visibility of instruments and mirror design.
