Definitions

  • This invention relates to a navigation system for use in a vehicle, the system comprising a memory for storing route information data, a position detector for determining a current position of the vehicle, a processor being arranged for generating travel information and an output for providing the travel information.
  • This invention further relates to a method for providing travel information in such a navigation system.
  • Navigation systems are often used in cars for guiding a user from his or hers current position to a destination.
  • the user uses a user interface of the navigation system to enter the destination into the system.
  • a processor of the system uses stored data describing a modeled version of real world roads to calculate a shortest, fastest or otherwise optimal route.
  • the navigation system While traveling along the planned route, the navigation system provides directional information to the user in audible and/or visible form. Additionally, the navigation system may provide traffic information, such as information about road blocks or traffic jams. Sometimes, the navigation system also provides other types of travel information, such as a distance to the most nearby gas station, restaurant, hotel or touristic site.
  • users tend to only use the navigation system for planning routes to destinations they have never or rarely visited before. After traveling to a certain destination several times, the user knows the route and no guidance by the navigation system is needed anymore. Only when a user expects traffic jams, e.g. when traveling from home to work during rush hours, he may choose to use the navigation device in order to receive relevant traffic information. Consequently, the user may miss important travel information when traveling a known route.
  • this object is achieved by providing a navigation system for use in a vehicle, the system comprising a memory, a position detector, a processor and an output.
  • the memory is provided for storing route information data.
  • the position detector is for determining a current position of the vehicle.
  • the processor is arranged for determining at least one predicted destination based on the current position and the route information data, determining at least one predicted route based on the at least one predicted destination and generating travel information concerning the at least one predicted route.
  • the output is provided for providing the travel information.
  • the navigation system proactively informs the user of the system about relevant travel information while traveling, even when there is no planned route.
  • the travel information may, for example, be traffic events (traffic jam, road block, slow traffic) or approaching a point of interest such as a speed camera, traffic light camera or a school.
  • the current position of the vehicle and the route information data together provide useful information about destinations the user will probably (or likely) visit.
  • Such a predicted destination may be either a final destination of the current trip or a point to be passed while travelling somewhere else. For example, when the system detects that the vehicle is on a certain highway and will run into a traffic jam if following this highway for another 10 km, the user may be informed about the traffic jam he will run into.
  • the system may then also suggest taking another route, even when no destination has been entered into the navigation system.
  • the route information data comprises driven routes
  • the processor is further arranged for determining a relevance of at least one of the driven routes based on the current position and determining the at least one predicted destination based on the current position and on the determined relevancies.
  • the navigation system gains knowledge about the places the user visits frequently and about the routes the user usually follows when traveling to these places.
  • the system can calculate a relevance of the stored routes, i.e. a probability of the user traveling to one of the known destinations via one of the stored routes. For example, the relevance of a stored driven route may be high when the current position is close to the starting position or the destination of the stored driven route.
  • the relevance of a stored driven route may also be high if the current position is on or close to the optimal (e.g. shortest or fastest) route between the starting point and destination of the stored driven route.
  • the system may come up with one or more predicted routes. Subsequently, the system may generate relevant travel information related to the predicted route. If the current position is on one of the stored driven routes, the probability of the user following this stored driven route is high.
  • Other useful parameters for determining the relevance of a route is the current time of day or day of the week, a travel direction, the current route for as far as already traversed or the starting point of the currently driven route.
  • the relevance of a stored driven route may also be influenced by, e.g., the weather (go to the beach), data from the user's agenda (e.g. obtained via wireless communication with a mobile phone or PDA of the user) or the presence of other people in the vehicle.
