A vehicle navigation system (,) comprises a planning module (,) for planning a route between an origin and a destination and subsequently guides the driver along the planned route. The system further comprises a receiver (,) for the reception of traffic messages related to problem locations on roads, which messages are transferred to the driver. The navigation system according to the invention is arranged to read from its storage medium (,) with the map database additional information (,) indicating the potential problem locations for roads in the database. In this way, the information from the traffic message can be combined with the information from the map database and further exploited in the system, e.g. for planning a new route.

Navigation system for providing an optimal route from traffic messages

A navigation system (,) guiding a driver of a vehicle has a receiver (,) for the reception of traffic message. The navigation system has a filter module (,) that determines the delay caused by the event of the received traffic message. The filter module only transfers the traffic message to the process module (,) of the navigation system if the delay is larger than a threshold (,).

Navigation system for a vehicle

An apparatus for supplying traffic-related information in a vehicle receives a message concerning a traffic-related event, for instance a traffic queue. This message contains information about the location of the traffic-related event. The apparatus calculates the time and/or distance interval between the location of the event and the current position of the vehicle and gives an alarm if the time and/or distance interval is smaller than a predetermined time and/or distance interval.

Apparatus for supplying traffic-related information

In a navigation system a driver of a vehicle is guided along a planned route (310) from an origin to a destination. The system comprises a receiver (122) for receiving a traffic message of an actual travel condition concerning a road-element. The system comprises an evaluation module (126) to determine whether the received traffic message makes it necessary to plan a new route to the destination. If a traffic message is received for a road-element which does not form a part of the planned route (212), the evaluation module determines whether the message indicates an improvement (204) of the travel condition of that road-element and if this is so then the planning module plans a new route.

Navigation system and method for guiding a road vehicle

An interactive image display device comprises cursor control means which, realize the movement of a cursor in a direction of a first and a second coordinate axis on the screen, respectively, in dependence on whether a control knob is rotated counter-clockwise or clockwise in order to change an adjustment.
