Networked automotive scenarios

Anastasius Gavras

In the catalogue of options of premium class cars you will find advanced systems aiding the car driver in various situations that occur almost every day. Parking aids, airbag pre-crash sensing, adaptive cruise control or stop-and-go functionality are just a few examples. These systems are made possible by recent technological advances in sensor devices that are available today. However, the future has more exciting applications to offer.

The previous examples are realised by sensors that do not communicate outside the car they are built in. The next generation of automotive sensors will communicate with their peers, the other cars’ sensors, and share the data and interpretation of the environmental conditions they sense. Enabling a wider range propagation of the sensed conditions by means of suitable ad hoc networks, means that drivers in cars several kilometres away can be informed or warned about road blocks, accidents, heavy traffic or icy roads in just a few seconds. Such information can be easily integrated in today’s navigation systems, improving their accuracy and performance.

Furthermore, enabling the car to communicate with its environment, offers opportunities for information services and marketing. The benefits of such advanced driver assistance applications are obvious. For example, they will help to increase road safety by reducing the number of accidents as well as to lower the overall impact of non-avoidable accidents. Distributing information about traffic flow will help in smoothing local traffic flow, thus contributing to increased highway throughput and energy efficiency. Finally services can be built that offer increased comfort and business applications to drivers and passengers.

Additional information services are enabled if the sensors communicate with their environment, such as the entrance to the car park of a super market. Use your imagination to figure out the advertising possibilities for the super market. Another example is that a gas station could advertise its gasoline price to all cars in its vicinity – a valuable piece of information, considering the high gasoline prices.
