Japanese manufacturers to cooperate on vehicle communications standards

Suzuki, Subaru, Daihatsu, Toyota and Mazda say they have reached an agreement to jointly develop technical specifications for next-generation vehicle communications devices and to promote the common use of these communications systems.

The companies state that within the field of CASE (connected, autonomous/automated, shared, and electric) vehicles, rapid advances are being made in the connected domain, in relation to the communications and data aspects of technology, including cloud services, IoT, big data and AI. However, individual automobile manufacturers are independently developing vehicle communications devices. Even in cases where the same connected services such as remote operation functions are available, each company is adopting a different approach to development and deployment of such systems.

In response to this, the companies aim to position the development of vehicle communications devices, which are basic functions of the connected car, as a cooperative domain, achieving greater efficiency and accelerating the development of said devices.

As a result, each company will be able to focus more on the development of applications and services on this common infrastructure. By stabilizing the communication quality between vehicles and the vehicle communications device center further, it will be possible to provide more convenient connected services to customers. 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 add new functions.
