Toyota Motor, with the help of Japanese telecommunications operator KDDI, plans to build a global communications platform that it hopes will speed up the deployment of connected-car technologies.

The platform will bring greater connectivity to Toyota and Lexus cars around the world, using a new standard data communications module (DCM) that will be ready for deployment in 2019, Toyota said. The DCMs will offer connectivity that doesn't require global roaming services. That will be possible by building on relationships KDDI already has in place with more than 600 telecommunications carriers worldwide.

Toyota and KDDI will jointly conclude new agreements with those carriers. The platform will then also be made available to other interested companies.

"Communications technology is essential to enhance vehicle connectivity," Toyota senior managing officer Shigeki Tomoyama said in a press statement. "The joint establishment of this global communications platform with KDDI will help us offer a more stable and higher quality connectivity service to customers all over the world."

Toyota said vehicle data collected with the help of the DCMs will also allow it to enhance product-related R&D.
