Speed Up Autonomous Cars


The future of connected cars, and ultimately the completely autonomous vehicles, isn’t so far away. Called V2X (vehicle-to-everything) communications, our cars, trucks, and even ships and drones can connect and communicate to the intelligent traffic infrastructure and other vehicles. Hence, the connected car will impact not just roadway object detection, but how the car and driver communicate with their electronic environments. These communication pathways include Bluetooth, GSM telephony, Ethernet for high-speed communications in-car, and specialized user interfaces (such as Android Auto or Apple’s CarPlay. These communication interfaces promote intelligent traffic management and help avoid accidents.

Traffic patterns with V2V and V2X

Autonomous cars with vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2X) communication capability will have a much better understanding of road and traffic conditions. V2V and V2X capability will allow autonomous cars to know the position of nearby traffic and make efficient traffic decisions. Autonomous cars will be able to not only vigorously re-route themselves basis anticipated traffic situations (just like advanced GPS systems today), but also will be able to escape creation of traffic jams in the first place.

Get the green light with V2X

Does it ever seem like your commute is in sync with a streak of green lights, or the opposite … red? With V2X, your car and other vehicles on the road connect in real time with the traffic lights, exchanging messages about proximity so the light can “extend” its green.

Vulnerable road users stand out with V2X


Pedestrians, cyclists or motorcycles, also known as vulnerable road users, can be “seen” with V2X. Once detected, warnings are sent to cars in the area.

Emergency vehicles get priority with V2X

The siren wails, but you don’t see an ambulance. Then out of the blue, it’s right behind you. Or maybe you don’t even hear it, until you see it in your rear-view mirror waiting for you to pull over. With V2X, your car tells you the location of the emergency vehicle before it’s within sight.

Fire engines, ambulances and other emergency vehicles also get a green light before they approach the intersection.

Challenges to adoption

One of the most important hurdles in the way of autonomous cars is customer acceptance, as many customers will be hesitant to completely rely on a machine.  However, to reach the point of customer adoption, we must first overcome and address the several technological challenges.

As autonomous cars are expected to generate over 1GB of data per minute, cars need to securely process multiple streams of information with flawless intelligence. Just like the human body, strong reflexes will be required in addition to the central brain to meet this challenge.

Technology for the secure, connected car is here 

As we move to the age of the ‘connected car,’ more functions of vehicles and road infrastructure will be accessible digitally, presenting both new opportunities and security threats. To safeguard systems against attack, we need to have the right technology for encryption and secure data exchange. This process begins right from the point of manufacture, which is why electronic chip manufacturers like NXP are continuously driving advances in this domain. We have been pioneering the connected car long before the term was used as part of ‘internet of things’ revolution.  NXP is leader for crypto- and authentication solutions, and aims to bring banking-level security into the automotive world.

While the potential threat of hacking does exist, security solutions that prevent network compromise and establish user identity have already been successfully applied in areas such as banking and e-identity, and are now available to the automotive market. We’re now entering an exciting new era where the latest information security technologies are becoming integral to the automotive sector.

In conclusion, the future cities will demand smarter solutions for urban living to deal with these problems, for instance intelligent traffic management solutions and connected automobiles. But, if we only connect the world and forget about security, it can lead to adverse consequences. Hence, we need to ensure our cars of the future are built with security in mind.
