Japanese hit each other on a pack
Toyota, Suzuki, Subaru, Daihatsu and Mazda want to develop vehicle communication together in the future. Standardization of technical specifications is intended to speed up the implementation process and provide greater security and convenience for networked services. Toyota provides the basic technology for collaboration.

Japanese hit each other on a pack
Mazda Motor Corporation has agreed with Suzuki Motor Corporation, Subaru Corporation, Daihatsu Motor and Toyota Motor Corporation to jointly develop technical specifications for vehicle communication devices. The partners also want to promote the shared use of communication systems. Standardization is intended to accelerate the introduction of safer and more convenient connected services, with the aim of creating attractive new values and services by connecting automobiles and society.
The fields of networking, automation, sharing and electrification (CASE – Connected, Autonomous/Automated, Shared, Electric) are currently causing major changes in the automotive industry. Especially in the area of networking, rapid progress is currently being made in communication and data, including cloud services, IoT, big data and artificial intelligence. Currently, automobile manufacturers are independently developing vehicle communication systems. Even in cases where the same services are offered, such as remote control functions, each company takes its own approach to developing and deploying appropriate resources.
Connected automobiles
By working together to develop vehicle communication systems that form the basis for connected automobiles, companies will be able to offer their customers even faster, safer and more convenient networked services. The development of applications and services is carried out individually by the manufacturers involved. This leads to faster and more efficient development of vehicle communication systems, while each manufacturer can focus more on developing its own applications and services based on the shared infrastructure. Suzuki, Subaru, Daihatsu and Mazda will work together to build next-generation connected car systems with common specifications for connecting vehicles, networks and the communications center. To do this, they integrate their own technologies into the basic vehicle communication technologies developed by Toyota.
The companies involved promise in a press release that the better transmission quality between the vehicles and the vehicle communication center will make it possible to offer customers more convenient networked services. This applies, for example, to better quality calls between the service center and customers as well as faster connection speeds. At the same time, the development effort of the individual participating companies will be reduced; System operation and version upgrades for additional functions are simplified. This saves additional resources such as facilities and personnel.
