V2V – Or Vehicle to Vehicle

V2V – Vehicle to Vehicle – is the industry term for when vehicles communicate directly with one another to gain situational awareness. Features like collision warning, detection and positioning already exist in modern vehicles and are important for the development of active safety features and functions. Systems that actively prevent to help drivers in critical traffic situations.

With our technology, vehicles can communicate position, direction and speed through programmed sensors even under radio shadows, which is not possible with GPS.

Terranet’s underlying technology supports both cellular V2X, 5G and Dedicated Short Range Communications, which is part of the industry organization IEEE’s wireless communications (802.11p) standard. In emergency situations, delay caused by poor connection can be the difference between life and death.

Terranet’s embedded software module for V2V is based on a patented non-GNSS algorithm for collaborative positioning between vehicles on the road. Thanks to this wireless communication technology, vehicles understand where they are in relation to one other and combined with mult-ihop technology we can extend the range by letting vehicles send information through each other.

The development of self driving cars is one of the hottest areas for car manufacturers today but before we see self driving cars on the street the industry needs to make sure it’s safe.



Multi-hop – node to node

Through relative positioning, vehicles can send signals regardless of access to GPS/GNSS and with multi-hop technology expand the range of communications between cars. The expanded reach makes it possible for cars and trucks to communicate with vehicles out of sight. The technology improves the vehicle’s active safety level significantly.

Active safety

Active safety is the collective term for systems that actively intervene to help drivers in critical traffic situations to avoid accidents. An active safety system contains several sensors, such as radar, lidar and cameras information from the surroundings. In that way, the automated system can warn and take actions to help the drives if an unforeseen situation.

The US National Highway Traffic Safety Administration (NHTSA) are proposing an implementation of a new active safety standard in all newly produced cars.

Platooning

Another example is when trucks are driving in a convoy – platooning –  to save fuel, they are connected to each other’s system to control speed, distance and position and have full sight thanks to video streaming and shared screens.

Terranet’s technology keeps the connection steady between trucks even when driving thought a remote area. By getting a wider sight and a better overview of the traffic situation the chances of preventing accidents is considerably higher.Besides the enhanced safety factor the fuel efficiency gains fram platooning provide real financial benefits.
