The integration of vehicles into communication infrastructures and contexts such as cloud services, IoT, big data and artificial intelligence is currently making rapid progress. But currently, individual car manufacturers are developing vehicle communication solutions independently. Even in cases where identical networked services such as remote control functions are offered, each company takes its own approach to the development and deployment of corresponding resources - according to the Japanese view.
In future, the idea is that car manufacturers should be able to offer their customers secure and convenient networked services more quickly. To this end, they aim to jointly develop vehicle communication devices that form the basis for connected cars. This will allow each manufacturer to focus more on developing its own applications and services based on the common infrastructure.
Currently, Suzuki, Subaru, Daihatsu and Mazda are jointly developing systems for connected cars with common specifications for the connection between vehicles, networks and the vehicle communication centre. In doing so, they are integrating their own technologies with the basic vehicle communication technologies developed by Toyota.
Part of the development activities is to optimise the transmission quality between the vehicles and the communication centre. This should enable the provision of better connected services, including better voice quality for phone calls and higher transmission speeds. At the same time, the joint activity should reduce the development effort of the individual participating companies and simplify system operation and version upgrades for additional functions.
The group did not initially provide further details. However, a functional diagram (see picture) suggests that the development is less about the hardware and software implementation in the vehicle itself and more about a common data platform and communication architecture.
The Japanese OEM group said it was open to working with other like-minded partners on the agreed joint development.
