V2X Interactions

Building a reliable CAV is only possible when numerous situations and interactions are considered – especially the unpredictable ones. In our world-class AV Living Lab, the environment is perfect for testing Vehicle-2-Everything capabilities and new business models.

A real-life 24/7 stimuli-rich environment offers you a wide array of everyday situations that your future vehicles will have to handle error-free.

V2X interaction can use several communication technologies that can be tested in an AV Living Lab environment.

Dedicated predominantly for V2V, DSRC (Dedicated Short Range Communications) in 5.8 GHz band (EU). Also intended for use in V2I, e.g. intelligent traffic lights and signs.

Cellular, mobile communication (4G, forthcoming 5G) in 800/900 MHz, 1.8 GHz, 2.6 GHz bands (EU). This covers the entire spectrum of V2X communications.

Mobile WiFi, IEEE 802.11p for V2V and V2I in 5.8 GHz band.

The most important use cases are:

Vehicle-to-Vehicle interaction and presence-indication

Various scenarios can be tested with automobiles communicating among each other on real traffic roads. Testing in closed and controlled laboratories is necessary and inevitable in the first stages of development, but testing in a real environment will identify new challenges that will need to be solved. V2V communication is not only possible with the vehicles in visible vicinity, but also with distant ones, indirectly via V2I and a cellular communication to inform of oncoming congestions or road accidents.

Vehicle-to-Device interaction

Many scenarios can be tested, based on the exchange of information between a vehicle and any electronic device that may be connected to the vehicle itself. Vehicle connectivity to mobile apps presents a great potential for a better driving experience by providing information regarding the surrounding vehicles and infrastructure, as well as making the interaction between the car and its driver much simpler.

Vehicle-to-Pedestrian interaction

The scenarios in which numerous interactions between vehicles and pedestrians are tested provide priceless information about potential pedestrian behavior. Avoiding any kind of error in future interactions between vehicles and people is the most important part of the development.

Pedestrians are equipped with smart communication devices that enable message transferring with vehicles – the device informs a pedestrian of the approaching vehicle and at the same time informs the vehicle of the pedestrian. This is inevitable in situations where nearby pedestrians cannot be seen due to objects in the way.

Vehicle-to-Home interaction

Future autonomous vehicles will not only be operated without a driver, but will even take care of the passengers. For instance, they will bring a person home or to any other chosen location, remotely turn on the heating, stop at the store to collect what is missing in the refrigerator at home, etc. These are only a few scenarios that you can test; the future will bring new challenges.

Vehicle-to-Business interaction

Various scenarios of communication between vehicles and an office or other business premises can be tested. A myriad of applications supporting V2B will be available for customers, business owners, and CAV itself to accomplish this multifaceted interaction. For example, when going shopping, our CAV will drive by BTC shops where deliveries will be waiting, according to our predefined lists or known habits.

Vehicle-to-Grid interaction

In this use case, various scenarios can be tested, e.g., a vehicle communicating with the power grid to sell demand response services by either returning electricity to the grid or by throttling their charging rate.

Vehicle-to-Grid can be used with “grid-ready” vehicles, i.e. plug-in electric vehicles (BEV and PHEV) with grid capacity. Since at any given time 95 percent of cars are parked, the batteries in electric vehicles could be used to let electricity flow from the car to the electric distribution network and back.

Vehicle-to-Infrastructure interaction

To build a fully autonomous and safe vehicle, Vehicle-to-Infrastructure testing interactions are crucial. An intelligent road infrastructure that enables the communication with surrounding vehicles, smart traffic lights, and signs are the necessary conditions for a successful development of vehicle autonomy.

V2X Interaction

Vehicle-to-Anything interaction sums up all the existing and new use cases of intelligent communication between a vehicle and its surroundings. The crucial design capability of CAV will be software updates of communication solutions, in order to adapt to new standards and new protocols. One major step towards this goal is also 5G communication that will support multiple modes of communication (voice, MTC, IoT).
