DENSO TEN Technical Review Vol.1 Efforts toward Realization of Connected Car Society Hiroyuki WATABE Hiroshi YAMADA Abstract It is generally said that“Connected Car Society” will come in near future along with the spread of the Internet and the development of IoT technology where almost vehicles are connected to networks and new services and businesses are created. Also, on the background of Global warming, Aging, Increase of traffic jam and traffic accident etc. by urbanization, Change of consumer needs, Change of society such as development of network society, Semiconductor technology, Mobile communication technology and Drastic evolution of ICT technology such as information processing technology including IoT, Big data, AI and others, a wave of big change such as Autonomous driving, Sharing and EV as well as Connected Car has been rushing to the field of automotive industry. In this paper, we introduce global trends for these environmental changes and DENSO TEN’s business vision focusing on connected car society. As our efforts to solve implementing issues, we explain the efforts toward advanced communication type drive recorder, on-demand data collection technology and providing of data interoperability.

Additionally, the 0 0 2014 2015 2016 2017 2018 2019 2020 2025 2030 2035 automotive industry and surrounding environment has changed greatly due to the increasing progress Fig. 1 Global Market of Connected Cars 1) in the use of big data which has accompanied the spread of the IoT, the evolution of AI by use of In the Connected Car Society, all sensors deep learning, and similar factors. It is certainly mounted on the car are connected to the network, safe to say that the“ Connected Car Society” will and it is possible to provide new value by analyzing come in the near future, resulting in nearly all and utilizing these data. vehicles being connected to networks, and new It also enables autonomous driving by using services and businesses utilizing this connectivity communication to supplement the high-definition will be created (Fig. 1). maps and information on locations where sensors cannot reach needed for autonomous driving. However, network connectivity also creates new security issues. Security countermeasures have become an extremely important issue due to the increased dangers such as illicit remote control 3 Efforts toward Realization of Connected Car Society that have arisen with the advance of electronically North America provides opportunities for business controlled vehicles. trials and practices in all aspects of“CASE” 2) through Currently, against a backdrop of an aging society, investing and securing inter-industry companies and environmental and energy problems, increased traffic start-ups aiming at autonomous driving realization jams and accidents due to increasing urbanization, and entry into mobility services by automobile social changes such as the development of a network manufacturers. For this reason, we has been society and sophistication of mobility services, the performing the following activities: advancement of semiconductor technology, and ① Research and exploration of seeds technology the massive evolution of ICT technology including through open innovation activities utilizing mobile and communication technologies (LTE-5G, universities and startups etc.), the IoT (with the cloud and similar functions), ② Study and creation of new distinctive service big data, and information processing technology (AI, ideas, and integration of seeds technology etc.), the automotive industry is awash in waves of ③ Solving issue by Proof of concept (PoC) great global transformations such as the advent of development and field testing the connected car as well as autonomous driving, In Europe, the European Commission with strong sharing, and electric vehicles (EV) (Fig. 2). leadership aims to enhance the competitiveness In response to such changes in society, DENSO of the European automobile industry, and the TEN have established“ Vehicle-ICT” as our business government supports the development of the vision and are promoting our business activities to EU industry against new threats (Google, etc.). realize the Connected Car society. In this paper, Amid this, the government is promoting the next- we present various countries’ efforts to address generation standardization on Autonomous driving these megatrends, issues to realize a Connected Car technologies and Connected technologies through Society, and our efforts. government-led projects related to autonomous driving. For this reason, we are working to gather Global Mega-trends information by strengthening the relationships with Changes in the Environment Surrounding the Connected Car Society: "CASE2)" local institutions and universities, in order to timely Environment Changes Conditions in 2030 Increased popularity of grasp the trends of standardization and assessment Increased Majority of passenger connected cars vehicles (90% of new popularity of (2020: 1/3 of the new cars sold in North America Connected equipped with a remote diagnostics function, cars) are connected connected cars launched virtual assist in the market, and in Europe and contribute to business, technology and increased popularity of music streaming) cars Increased 30% of traveling popularity of Start of services using product strategies. In Japan, while looking at these distance by Automated autonomous autonomous driving vehicles autonomous driving driving vehicles (From 2020: Level 3 or higher) activities in Europe and the United States, industry, Shared Emergence of Shift in values from Max. 50% are shared sharing vehicles government and academia collaborate, promoting & Services services "Owning" to "Using" International consensus activities to solve problems of Connected Car Society 25% are xEV Conversion Powertrain regarding global warming (Based on amount of countermeasures diversification vehicles sold) to EV (Paris Agreement) through deregulation and demonstration testing.
