Automotive Electronics
Making talking cars a reality
Maurice Geraets looks in detail at how the automotive industry is working to create a new customised and more entertaining experience for the driver but which at the same time makes driving both safer and easier
A
s the automotive industry continues to evolve at a rapid rate the car as we know it is
transforming from a simple mode of transport to a personalised mobile information hub – with various connections to the outside world. These innovations will not only create a new entertaining, customised experience for each individual but will also make it safer and easier to drive.
The concept of the connected car is widely understood, but the core elements that will actually come together to form the connected car are still a matter of discussion. Although not all of the elements are clear, we do however know that one of the biggest components of this will be vehicle-to-X communications (V2X) - intelligent systems integrated into vehicles capable of collecting and analysing data from other vehicles (Vehicle2Vehicle) and from

the supporting infrastructure (Vehicle2Infrastructure).
If a number of vehicles can transmit information from their various sensors about location, speed and other data, a dynamic model can be created to help drivers to understand real time current road traffic situations. As well as this being useful for the driver in terms of knowing where heavy traffic is and if a car needs any maintenance work, it can also help reduce the amount of traffic incidents. Ultimately, it is also a greener and more efficient way of driving. Overall road safety can be improved significantly, especially in critical traffic situations at high speed or in bad weather conditions.
V2X to driving innovation The potential for V2X is enormous. According to a study conducted by the U.S. Department of Transportation, V2X safety functions such as collision-

mitigating at intersections, and emergency braking assistants can reduce accident figures by more than 80 percent. With there being around 1.2 million people killed in traffic accidents and fifty million injured every year, this technology could save millions of lives. If anonymised data can be collected it can help public sector organisations gain a better insight and intelligence about road conditions. For example if data is collected from cars regarding ambient temperature it can signify when snowy weather may occur so local authorities can prepare the roads properly. Road defects can also be more easily spotted by analysing in-car data. If cars are braking and swerving in a particular location or suspension data registers severe vibrations in the road, repair crews can be sent directly to that location. Before V2X can become a reality,
