Report : Methodology of technology integration toward establishing an open innovation hub−67−Synthesiology - English edition Vol.4 No.1 (2011) In the future, as the scale of required resources for new technologies development will increase, technological seed sowing led or supported by government will be more important than now. In commercialization stage, open collaborations will be effective and inevitable.The case of car navigation and route guidance systemHajime Ito (Former Managing Director, Yazaki Meter Co., Ltd.; former General Manager Body Engineering Division, Toyota Motor Corporation)The precursor of navigation was the celestial navigation using a marine sextant and the radio navigation for aircrafts. In thinking about measuring one’s present location and which way to go, these are highly important technologies in the development of automotive navigation.There is 30 years of history in automotive navigation and route guidance system. The early automotive navigation was dead reckoning, where the “present location” was entered and the direction sensor was used to determine how one could reach the destination by following the directions. It is surprising that the three Japanese automobile manufacturers came up with similar technologies and products at the same time around 1980. The companies were searching high and low for various technologies, and realized that they could do certain things using certain technologies, and started to create similar things at once. I have been involved in design for about 20 years, and I repeatedly experienced the situation where similar products appear within a span of a year. I think “corporate competition” is the keyword. In the latter half of the 1970s, various government agencies including the Ministry of International Trade and Industry conducted research on some of the functions of the current navigation. Navigation appeared in 1980 as the crystallization of various technologies including display, memory, microprocessor, and others. Since then, the product power of car navigation increased, it became multifunctional, and became an essential product for cars. For the device to be installed in the car, it had to be incorporated in the design of the automobile, and the automobile companies began to install it as standard equipment.In the technological field, navigation is considered as a field of intelligent transport system (ITS). The team developing the ITS and the team standardizing it are working side by side, to develop the product, standardize, and to advance it as the world standard. The ITS Promotion Council is a Japanese organization to discuss ITS among government, academia, and industry. The activities are done under the supervision of this organization, and the manufacturers are not working individually. This is an important point.For human factors, the HARDIE guideline was created in Europe, but Japan had made many navigation systems after 1980, and the guideline of the Japan Automobile Manufacturers Association (JAMA) became the basic guideline of the world standard or the human factor requirements. For example, one cannot set the destination while driving, the map display disappears when one enters the community road, the prefectural roads are shown preferentially in the route guide, or one cannot watch TV while driving. These conditions created in Japan became the world requirements, then became the requirements considered by the ISO, and as a result, became the guideline of the Ministry of Land, Infrastructure and Transport. Since the navigation is not a prerequisite for driving, it is placed some distance from the center of driver’s vision, yet it is placed in a fairly visible place to prevent accidents if the driver looks at it while driving. I described the display requirements earlier, and the manufacturers must, of course, follow the requirements, but they must provide added value to their products in other areas. It will eventually become safe to view it while driving and be useful to the driver. That will be the future automotive navigation product.Evolution tree of automotive navigation1970 1990 2000 1980 Compass Electronic compassNavicomElectro-gyrocatorNavigation and route guidance systemElectro-multivision Pedestrian navigationHandheld navigationSmart phoneVICS GPS MapdatabaseDisplaydeviceCRT TFT MemoryCassetteCD DVD cpu 16 bit 32 bit C.C.

The Large-scale R&D of Optoelectronic Measurement and Control Systems Project had been underway at around 1980, but what is the difference between the situation at that time and the current “what”?Suzuki“What” arises from “why it is necessary”. In the history of electrical engineering, I analyzed how the technology was born from a certain social background and social demand. The air conditioner was first used for cooling only, but with the development of the inverter and heat pump, it became usable for both cooling and heating. Currently, there are
