Progress of Nissan’s technological development1. Introduction2. Technology roadmapPrefaceCorporate Vice President Mitsuro AntokuA new technology is established in a step-by-step manner from basic research and development (for creating the basis) to advanced development (for practical applications). After completing the research and advanced development of individual technologies, it is possible to combine them to create a new technology. However, the advanced development process is completed, these technologies may not yet be ready for product application. In such cases, it is crucial to continue the development activities to achieve the original roadmap.The research and development of motors and batteries, which Nissan had started prior to 1990, did not bear fruit until 20 years later in 2010 as the product Nissan Leaf, the worldʼs first mass-produced EV, and until 2017, as Nissanʼs unique electrification system e-POWER, which offers new value to many of our customers. Another example is e-4ORCE technology, which originated from the 4WD control technology ATTESA ETS and chassis control technology HICAS, which were cutting-edge technologies in the 1990s. They have evolved over the years, integrated with electrification technology, and bore fruit as an integrated control technology e-4ORCE. The e-4ORCE technology performs minute integration control of the front/rear motor drive AWD and chassis system such that the ease of handling, ride comfort, and sense of security can be realized at a high level in any driving scenario.Nissan's VC-TURBO engine, which achieves both high power and low fuel consumption through its variable compression ratio mechanism, took 18 years to develop from its conception to realization. The impressive results achieved were the result of the dedication and hard work 3. Research and development to advanced History of e-4ORCEdevelopmentWith the spirit “Do what others wonʼt” in our DNA and as indicated by the vaunted name “Technology of Nissan,” Nissan has created values through technology and delivered them to our customers as products and services.Any advanced technology is meaningless unless its resulting product can be used with pleasure by customers and unless it contributes to solving social issues such as global warming and traffic accidents. This preface describes how advanced technologies necessary for offering such value are born, nurtured, and applied to products.At Nissan, the roadmap for developing technology required to realize future visions was created long ago. All research and advanced developments are conducted based on this technology roadmap.The technology roadmap was created considering the following: “What values offered in our future products and services will our customers find attractive?” To answer this, the requirements and trends of society, as well as the issues that arise from them, are investigated. Technological developments necessary to realize a solution to such issues are incorporated into this roadmap.In most cases, establishing a new technology requires a long time. Therefore, it is crucial to develop a roadmap, which is a long-term technological strategy. Further, it is important to update this technology roadmap considering changes in social trends, changes in customersʼ values and activities, and the evolution and innovation of the technology. The technology roadmap for electrification and intelligence are shown as examples.even after sometimes, 1Technologies and processes for establishing products from advanced technologies
