Abstract

A pedestrian route navigation system (“PRNS”) in a vehicle capable of determining a route from a final parking position of the vehicle to a predetermined destination, comprising a final parking position unit and a pedestrian route calculation unit. The PRNS may include a display unit capable of outputting data concerning the route to the predetermined destination, and a transmitting/receiving unit capable of transmitting the data to a mobile information unit of the user of the vehicle.

Claims

1. A method for indicating a route to a predetermined destination in a vehicle, comprising:

detecting a current position of the vehicle;

determining a route from the current position to the predetermined destination;

detecting whether the vehicle has reached a final parking position for the predetermined destination;

determining a route from the final parking position to the predetermined destination; and

outputting data describing the route from the final parking position to the predetermined destination.

2. The method of claim 1, further comprising enabling and disabling the output of data describing the route from the final parking position to the predetermined destination.

3. The method of claim 1, wherein determining a route from the final parking position to the predetermined destination includes determining a pedestrian route from the final parking position to the predetermined destination utilizing roadmap data comprising pedestrian roadmap data and line tables data.

4. The method of claim 3, further comprising:

calculating a value of complexity for each section of a pedestrian route;

summing the complexity values for the entire pedestrian route;

comparing the summation of the complexity values to a threshold value; and

enabling or disabling the outputting of the pedestrian route responsive to the comparison of the summation of the complexity value to the threshold value.

5. The method of claim 1, wherein outputting data describing the route from the final parking position to the pedestrian destination further comprises outputting the direction of the predetermined destination relative to the final parking position, outputting the time it takes to arrive at the predetermined destination, outputting the pedestrian route to the predetermined destination, and outputting characteristics of the pedestrian route to the predetermined destination.

6. The method of claim 1, wherein detecting whether the vehicle has reached the final parking position further comprises detecting whether the engine of the vehicle has been turned off.

7. The method of claim 1, further comprising transmitting the data concerning the route from the final parking position to the predetermined destination to a mobile information unit of the user of the vehicle.
