Method for increasing accuracy of sensor-detected position data of e.g. truck, involves assigning toll station position with higher accuracy than vehicles position, and correcting vehicles position on basis of exact position of toll station |
摘要 |
<p>The method involves determining a position of vehicles (10, 10', 10'') using global positioning system-sensors (14, 14', 14''). A position of a toll station (12) is transferred from the toll station to the vehicles at a time point, at which the vehicles pass the toll station. The position of the toll station is assigned with a higher accuracy than the position of the vehicles. The position of the vehicles is corrected on basis of the transferred exact position of the toll station. A distance of the vehicles to the toll station is smaller than a predetermined threshold value at the time point. An independent claim is also included for a method for detecting sudden, temporary trouble or change of traffic route.</p> |
