Five Japanese automakers including Toyota Motor say they will work together to standardize how their vehicles communicate with drivers and external services.
The four other firms are Toyota subsidiary Daihatsu Motor, Suzuki Motor, Subaru and Mazda Motor.
They aim to bring automobiles further into connected lifestyles, including platforms like the Internet of Things, AI, and cloud computing.
The companies will start with jointly developing communication devices, and to link drivers with operators in cases of emergency.
They are also looking at enhancing connectivity for business opportunities.
The project comes under the name CASE, which stands for “connected, automated, sharing and electrification.”
The partners say by standardizing their systems they can cut costs and speed up development of next-generation vehicles. Up until now, the firms have used their own specifications.
Competition in the field is intensifying, as IT firms are also joining the race to increase connectivity on the roads.
