This paper describes an integrated CAD/CAM system on an EWS. This system is based on the CAD and CAM systems on large scale computers which have been developed and put into practical use in Toyota Motor Corporation. All the functions of these systems are compactly integrated into this system. We have established the following technologies through its development. (1) A method for construction of data structure common to CAD and CAM (2) A database structure that enables efficient data retrievals Owing to these technologies, a non-expensive integrated CAD/CAM system on an EWS has been developed, which can be introduced in small-sized parts suppliers. This system has already been put into practical use since early 1988, and used by more than ten suppliers. Much more suppliers are also planning to introduce this system in near future.

In recent years, advanced technology has become more and more important in the design of automobiles. Therefore, if we wish our products to continue to display their full potential to the people who buy them, thus ensuring customer satisfaction with our products, we must, even in the area of after-soles service, ensure that the technical proficiency and knowledge of our technicians will continue to keep pace with advances in technology. To do this, we must carry out effective “high-tech” training for our dealer workshops this is our present and future challenge Toyota's technical service training system is now applied to some 50, 000 service technicians in around 10, 000 workshops throughout the world, and the proposed report will introduce this system and give some actual examples of technical training that is actually carried out.

Detergent additives in automotive gasoline fuel are mainly designed to reduce deposit formation on intake valves and fuel injectors, but it has been reported that some additives may contribute to CCD formation. Therefore, a standardized bench engine test method for CCDs needs to be developed in response to industry demands. Cooperative research between the Petroleum Association of Japan (PAJ) and the Japan Automobile Manufacturers Association, Inc. (JAMA), has led to the development of a 2.2L Honda engine dynamometer-based CCD test procedure to evaluate CCDs from fuel additives. Ten automobile manufacturers, nine petroleum companies and the Petroleum Energy Center joined the project, which underwent PAJ-JAMA round robin testing. This paper describes the CCD test development activities, which include the selection of an engine and the determination of the optimum test conditions and other test criteria.

We urgently need to develop the next generation of automotive technology to support energy conservation and the global environment. For this we need an advancement of the Laboratory Automation System (LAS). However, restructuring the hardware and software of the LAS requires enormous amounts of time and costs. To solve the problems of the LAS development, we formed a user-vendor working group, which then established the common rules of LAS and IMACS (Integrated Measurement And Control System). IMACS are software-centered rules, characterized by the stratification of LAS and the interface called software parts. So far, we have integrated IMACS into five engineering fields. A total of 11 testing machine vendors participated in the development. We manufactured about 350 software parts and made their specifications openly available. As the next step, we are collecting software parts by deleting redundant functions.
