<p>The system has a chart of geographical data of road characteristics, where a continuous detection of a vehicle position is carried out through satellite navigation, through the detection of driven route, speed and a driving direction by using sensors. A driving route is detected through continuous comparison of the vehicle position with the data of the chart, where the navigation system is connected with another navigation system through a wireless data connection e.g. Ad-hoc-network.</p> |
