MAKING CONNECTIONS: New V2X technologies bring in smartphones, next-gen eCall

Vehicle-to-whatever communication technologies continue to be put through their paces around the world.

To point at just one example of the continued evolution of V2X technologies, let's take a quick visit to Japan and the 2025 JSAE Annual Spring Congress this May. That's where Toyota and Eye-Net Mobile Ltd., a subsidiary of Foresight Autonomous Holdings Ltd., presented a research paper on using vehicle-to-network technology to enhance ADAS systems by connecting to smartphones in the environment to address the inherent limitations of in-vehicle sensors.

Titled, “Feasibility Study of a Hazard Avoidance Brake Control System Using V2N Technology,” the paper examined how smartphones could act as external sensors that could connect to an onboard ADAS system using vehicle-to-network (V2N) communications. The main purpose of these signals would be for enhanced hazard detection, Toyota said, adding that some of the top issues addressed in the paper were “communication latency, tracking accuracy, and the positioning precision of these devices in diverse urban environments,” where direct line-of-sight isn't always possible.
