Explore the new horizons that 5G brings to connected vehicles and V2X communication

Connected vehicle technology is at the heart of ICT innovation in the automotive segment.

The interconnectivity of vehicles is an interesting solution that has helped reduce road accidents worldwide, which unfortunately killed 1.3 million people in 2018. Now we have to thank the vehicle-to-all technology (V2X) for integrating 5G technology and automotive software solutions to develop a new generation of smart automobiles that enhance the driver experience and reposition automakers for success.

How the vehicle connection enables communication with the external environment

Vehicles are now experiencing increased interconnectivity, interacting with navigation applications, on-board sensors, traffic lights, parking equipment and other automotive systems. Cars coordinate with their surroundings using certain capture devices such as dash cameras and radar sensors. Connected vehicles collect large amounts of data such as mileage, damage to geolocation components, tire pressure, fuel gauge status, vehicle lock status, pavement conditions and road conditions. parking conditions.

The architecture of connected vehicles for automotive industry solutions is powered by automotive software solutions such as GPS, DSRC (Dedicated Short Range Communication), Wi-Fi, IVI (In-Vehicle Infotainment), Big Data, Learning automatic, IoT, AI, SaaS platforms, and broadband connectivity.

V2X technology manifests itself in the form of synchronization between vehicles (V2V), vehicles and infrastructure (V2I) and vehicles and other traffic participants. By extension, these innovations can also accommodate pedestrians and cyclists (V2P). In short, the V2X architecture allows cars to “talk” to other machines beyond.

Navigation systems: data extracted from the map, GPS and detectors of other vehicles can calculate the arrival time of a vehicle carrying goods, the place of the accident for the insurance claim process , historical data for urban planning and carbon emission reduction, and much more.

Vehicle-to-Traffic Infrastructure: This covers signage, traffic prompts, toll units, workplaces, and university areas.

Vehicles to public transport systems: This generates data related to public interchange systems and traffic conditions, while recommending alternative routes when rescheduling trips.

The advantages of V2X integration with 5G

5G is the 5th generation deployment of broadband cellular connectivity. Basically, it works at a higher frequency range than 4G, which results in a connection speed that is 100 times faster than 4G. With this capacity upgrade, 5G offers greater functionality.

It processes data quickly, delivering 4ms in regular situations and 1ms at peak speed to ensure fast response from connected devices.

5G can meet the connectivity needs of one million smart devices per square mile.

Sadly, in the years since its 2019 release, the upgrade has bogged down in controversy and difficulty, culminating in its relationship to the recent global health crisis. However, despite its rocky start, 5G is now operational in 500 cities across the United States. Global penetration and adoption of the network is imminent, as projections for 2025 suggest that 5G will facilitate one-fifth of the internet in the world.

The deployment of 5G in V2X technology is inspired by the migration of cars to cellular infrastructure (C-V2X) – the latest and highest convention in the industry for connected and automated vehicles. Well-known car manufacturers like Audi, Ford and Tesla have already equipped their vehicles with C-V2X technology. For the context:

Mercedes Benz worked with Ericsson and Telefónica Germany to install 5G automated connected vehicles during the production phase.

BMW has teamed up with Samsung and HARMAN to announce the BMW iNEXT, which features a 5G-based Telematics Control Unit (TCU).

Audi announced in 2017 that its vehicles will be able to interact with traffic lights to alert drivers when they change from red to green.

The potential of C-V2X is so limitless that its components are already in use in more than 500 cities, counties and university districts, providing autonomous connectivity to traffic systems, energy infrastructure and construction facilities.

Main use cases of V2X in cars

With C-V2X comes transportation safety, efficiency and a high driver / pedestrian experience (a good example is an acoustic vehicle alert system). It allows investors and think tanks to explore new avenues for large-scale development through a plethora of scenarios. By initiating “digital telepathy” using sensors and historical data, for example, coordinated driving can be achieved, collisions can be avoided, and safety warnings can be observed. Let’s take a deeper look at the many V2X applications supported by 5G.

Truck platoon

It is the cybernetic chain of trucks on the highway in convoy. Proximal vehicle alignment enables synchronized acceleration, steering and braking, resulting in greater on-road efficiency, fuel economy and emission reductions. The lead truck determines the route, speed and spacing of other trucks. 5G trucking makes it possible to travel long distances safely. For example, when three or more cars are driving and a driver dozes off, the truck will automatically follow the lead of the pack, mitigating the risk of a drowsy driver. In addition, when the lead truck performs an evasive maneuver, the other trucks behind will react simultaneously. OEMs like Scania and Mercedes have rolled out models on the road, while several US states have adopted automated truck tracking. According to Scania Group, the bunch of trucks can cut emissions by up to 20%.

Cooperative conduct

It is a connected vehicle breakthrough in the way cars interact with traffic conditions. A car equipped with the V2X architecture can broadcast sensor information with other motorists to coordinate its movement. This can happen when one vehicle passes and the other automatically decelerates to accommodate the maneuver. The active coordination of motorists has been shown to be effective in limiting interruptions resulting from lane changes, sudden braking and unplanned maneuvers. In the real world, coordinated driving is impractical without 5G technology.

Collision prevention

This mechanism supports the driver by providing notifications of any impending collision. This usually results in automatic steering repositioning or forced braking. To prepare for a collision, a vehicle transmits its position, speed and direction relative to other vehicles. Thanks to this vehicle connection technology, the motorist can avoid hitting cyclists or pedestrians by simply discovering their smart devices. The inclusion of 5G amplifies this functionality by allowing a wide range of connections between multiple vehicles to determine the precise location of each in relation to other participants in traffic.

Unmanned driving

Automatic cars rely more on fast data streams than any other class of vehicles. Fast response times accelerate real-time driver decision making under varying road conditions. Locating the precise position of a pedestrian or anticipating the next red light are scenarios where this technology demonstrates its viability. The speed of this 5G solution means processing data in the cloud via AI enables the car to make precise decisions instantly but without assistance. By interpolating data from smart cars, machine learning (ML) approaches can manipulate a vehicle’s environment; stop cars, slow them down or order them to change lanes. Plus, the powerful association between 5G and edge computing processes datasets faster.

Interestingly, the benefits seen in the automotive segment spill over into the energy and insurance segments.

Take away food

5G is the digital solution that is sending the automotive world into unprecedented gains by advancing the way we use wireless connectivity to navigate. It supports large amounts of connections in small areas and captures precise locations faster than any previous technology. The 5G-powered V2X architecture is highly reliable with minimal delays, providing a range of benefits such as ease of connectivity, rapid data capture and transfer, improved road safety and improved vehicle maintenance.
