Abstract

A navigation system and method having a function of alerting the driver to potential wrong way driving comprises means 102 for determining a position of a vehicle 300, means 107 for calculating a driving route of the vehicle 300, means 108 for determining a driving manoeuvre in accordance with the predetermined driving route 305, means 104, 105, 110, 111 for outputting indications relating to the determined driving manoeuvre to a driver of the vehicle 300, and means 109 for alerting the driver to potential wrong way driving including means 201 for detecting a potential wrong way driving situation and means 202, 104, 105, 110, 111 for outputting an indication relating to the potential wrong way driving situation to the driver.

Claims

1. A navigation method for guiding a driver of a vehicle comprising;

predetermining a driving route of the vehicle;

determining a position of the vehicle;

determining a driving maneuver in accordance with the predetermined driving route;

alerting the driver to potential wrong way driving by detection of a potential wrong way driving situation; and

outputting an indication relating to said potential wrong way driving situation to the driver, if a potential wrong way situation has been detected.

2. The navigation method according to claim 1, further including:

detecting a potential wrong way driving situation when at least one value of a at least one parameter relating to an operation state of the vehicle;

determining at least one value of at least one parameter relating to an operation state of the vehicle based upon the predetermined driving route;

comparing the detected value and the determined values; and

judging the result of comparison to detect a potential wrong way driving situation.

3. The navigation method of claim 2, where the determined value is based upon traffic provisions along the predetermined driving route.

4. The navigation method of claim 2, where the determined value based upon the determined driving maneuver.

5. The navigation method of claim 2, further includes:

determining a location of the predetermined driving route where it is possible to leave the predetermined driving route.

6. Navigation method of claim 2, where the determining the at least one value further includes:

determining the at least one value within a predetermined distance to a point of the predetermined driving route where the driving maneuver is to be performed.

7. The navigation method of claim 2, where the at least one parameter(s) is selected from a group of parameter comprising:

a geographical position of the vehicle, a relative position of the vehicle with respect to at least one location of the predetermined driving route, an advancing direction of the vehicle, a position of a direction indicator control, a vehicle speed, a rotational speed of the vehicle, and a time period during which any parameters are within one or more predetermined ranges of values.

8. The navigation method of claim 7, where value of the respective parameter is selected based upon another value of another parameter and a distance to a point in the predetermined driving route where the determined driving maneuver is to be performed.

9. The navigation method of claim 2, further comprises:

determining an output information related to said predetermined driving route which is to be output to the driver upon detection of the potential wrong way driving situation.

10. The navigation method according to claim 2, further comprising:

inputting information relating to a desired driving route;

and calculating the predetermined driving route in accordance with said input information.

11. The navigation method according to claim 2, further comprising selecting a driving route from a plurality of driving routes stored on a storage medium of an external server.
