Intelligently connected
"Vehicle to everything" (V2X) summarizes the various communication paths of vehicles with their environment. Particularly exciting is the direct communication from vehicle to vehicle (V2V – Vehicle to Vehicle) and vehicle to infrastructure (V2I – Vehicle to Infrastructure), where no mobile network is required.
The basic idea of V2V is that every vehicle periodically transmits its position, speed, direction, and other parameters. This allows every road user to gain an accurate overview of their environment and to recognize potentially dangerous situations. Specific messages are also sent out for special events, such as emergency braking or a stalled vehicle.
V2I complements the transmission of sign contents, traffic light phases, and intersection layouts to the vehicles. This increases safety, enables efficiency gains and thus sustainable mobility. Automated driving can also benefit significantly from this information, which is then available digitally. Infrastructure equipped with additional sensors can report detected objects via V2I to other road users, thereby protecting the vulnerable road users (VRUs) like pedestrians and cyclists from being overlooked.
Another component of V2X is the well-known communication via the mobile network (referred to here as V2N – Vehicle to Network). This can be used to transmit more extensive information, for example, a traffic jam or a blockage 10 km away, which the navigation system can consider for new route planning.
