Research paper : Integrated development of automotive navigation and route guidance system (H. Ito )−163−Synthesiology - English edition Vol.4 No.3 (2012) navigation, safety must be ensured to obtain acceptance of society, since it is a device operated and viewed while driving. Therefore, in chapter 4, the R&D for human factors, the activities to establish international standard, and the development of guidelines for promoting social acceptance will be described.The technologies that comprise navigation span across wide-ranging fields. Therefore, as shown in Fig. 1, the technologies for product realization and the supporting technologies, as well as the activities for social acceptance will be described. The technologies that have become obsolete are shown in dotted lines. While Ikeda et al.[2] specifically discusses the on-board and infrastructure technologies needed for navigation from the standpoint of a navigation manufacturer, in this paper, I write from the standpoint of the car manufacturer that places importance on the integrity as a on-board equipment and its social acceptance. 2 History of planning and product realizationOne of the objectives of the car manufacturer is to sell the car, and it is important how much the functions and equipment in the car provide satisfaction to customers in terms of convenience, safety, entertainment, and design. It is a matter of cost-effectiveness.The navigation was developed from the engineer’s dream that the customers might be pleased to see such a product.Since its launch, the navigation became standard equipment in high-priced, high-grade cars, and many highly competitive aftermarket (market for non-genuine parts and equipment) products were introduced. As a result, it became an element that must be included in the basic structure and design of the instrument panel where the navigation will be installed, early in the process of automobile planning. This involved wisdom and effort spent on the numerous aspects of design, evaluation, and manufacturing, such as the car design, strength, durability, visibility and operability during driving, ease of installment and removal, electromagnetic compatibility, and collision safety. 2.1 Early planning: Realization of technology to satisfy the [presence of demand] and [presence of example]The objective of the navigation is, as stated before, to guide the driver to the destination. The product planning will involve making a device that indicates the route in a legible, understandable, and precise manner while driving.The first product was the electronic compass launched in 1980, and this received and displayed the current bearing Fig. 1 Development of technology(Evolution of human interface)20102005JAMA GL.3Probe (floating)HDDKIWI,iFormatTelematicsSD card2000D-GPSVICSDVDEstablishment of ISO 2WG1995Integration of ISO WGRoute guidanceEstablishment of Subcommittee, Society of Automotive Engineers of JapanTFT-LCDGPSJAMA GL.1Establishment of Naviken and JDRM1990CDMap matchingElectronic mapCommunication, telephoneWheel rotation sensorCassette memoryColor CRT1985CRTGyroscopeSpeed sensorBearing sensor1980(Map DB)(Link with Infrastructure) (Memory)(Display device)(Position identification, route finding)
