Connectivity refers to digital networking or the ability to be networked. This is achieved thanks to modern means of communication via online connections through the Internet.
In the field of mobility, the term connectivity stands for the mobile networking of all mobility participants. Mobile networked are not only the drivers themselves but also the vehicles among each other and with the infrastructure. In cars, this is made possible by so-called Car-to-X technologies, with which the vehicles exchange information in real time. This exchange takes place completely independently via mobile radio or WLAN.
In most cases, special technologies are used in the vehicle to ensure that the driver benefits from this connectivity. For example, the vehicle can be warned automatically in the event of an accident, exceeding the speed limit or safety warnings.

Basically we distinguish between 5 types of connectivity in vehicles:
Vehicle to Infrastructure (Vehicle to Environment)
Here, the technology collects data generated by the vehicle and provides the driver with assistance and information about the environment. The focus here is on communicating information on safety, mobility and environmental conditions (traffic, weather, etc.).
Vehicle to Vehicle (vehicle to vehicle)
The technology exchanges information from other road users in the vicinity with their own vehicle. Here, for example, information is exchanged in order to avoid accidents.
Vehicle to Cloud
This is where information is exchanged via the application in vehicles with the cloud. This is where information is processed that contacts technologies connected via the cloud. Data for transport (with the fleet manager), energy related or in the private sector with ‘Smart Homes’ are typical applications here. This V2C communication becomes very important for the use of electric commercial vehicles, since arrangements at the charging stations for the electric vehicles can already be made ‘on board’ semi-automatically or fully automatically.
Vehicle to Pedestrian
The technology collects data about the environment and communicates it with other vehicles or other contact points in the vicinity. This improves safety on the road. A very useful example here is the early detection of the movement of a pedestrian behind parked vehicles in the city and the resulting automatic brake assistance to avoid a collision with this pedestrian.
Vehicle to Everything
The technology connects all types of vehicles and infrastructure systems with each other. Communication partners can be other vehicles, infrastructure such as vehicles or tank and charging stations, aircraft, helicopters or drones, trains or ships.
