Suzuki, Subaru, Daihatsu, Toyota, and Mazda have reached an agreement to jointly develop technical specifications for next-generation vehicle communications devices. The agreement will also see the Japanese OEMs promote the use of communications systems by using connected services to link automobiles and society – with the aim of creating new appeal, value, and services to be standardized for early provision of safer and more convenient connected services.

Within the field of CASE (Connected, Autonomous, Shared, and Electric), rapid advances are being made in the connected domain in relation to the communications and data aspects of technology and business – including cloud services, IoT, big data, and AI. Individual automobile manufacturers are independently developing vehicle communications devices. Even in cases where the same connected services (such as remote operation functions) are being provided, each company is adopting a different approach in proceeding with development and deploying relevant resources.

In response to these circumstances, the companies can provide safer and more convenient connected services to customers as early as possible, by positioning the development of vehicle communications devices, which are basic functions of the connected car, as a cooperative domain; positioning the development of applications and services as an in-house domain; and achieving greater efficiency and accelerating the development of vehicle communications devices. Through these steps, each company can focus more on the development of applications and services on this common infrastructure.

At this time, while incorporating their own technologies into the base vehicle communications technologies developed by Toyota, Suzuki, Subaru, Daihatsu, and Mazda will build systems for next generation connected cars with common connection specifications from vehicles to networks and the vehicle communications device center. As a result, by stabilizing the communication quality between vehicles and vehicle communications device center further, it will be possible to provide more convenient connected services to customers, such as clearer phone calls and faster connection speeds. At the same time, it will be possible to reduce the development burdens of each participating company and simplify system operation and version upgrades that include additional new functions, thereby optimizing resources such as facilities and personnel.
