Abstract

Proposed is a method and a navigation device, a method for selecting map information from a digital map on the basis of a predefined polyline being used on the digital map, and, in addition to the information defined by the polyline, the map information including further information regarding a route corridor.

Claims

1. A method for selecting map information from a digital map, comprising:

providing a predefined polyline that defines information;

selecting map information that includes a route corridor as a function of at least one parameter; and

if the at least one parameter provides for the selected map information being tolerant of an error, guiding a driver on one of a side route and an alternate route, wherein one of;

the at least one parameter provides for the selected map information to be tolerant of multiple errors in a starting region and a destination region of the predefined polyline, and

the at least one parameter provides for the selected map information to be tolerant of at least one error as a function of a class of a road.

2. The method according to claim 1, wherein the at least one parameter provides for the selected map information to include a navigational instruction.

3. The method according to claim 1, further comprising:

formatting the navigational instruction to lead back to at least one of a destination via the alternate route and to the predefined polyline on one of a shortest route, a quickest route, and a most efficient route.

4. A method of using a navigation device including a memory and a navigation computer, comprising:

a storing in a memory selected map information, the selected map information being selected by;

providing a predefined polyline that defines information,

selecting map information that includes a route corridor as a function of at least one parameter, and

if the at least one parameter provides for the selected map information being tolerant of an error, guiding a driver on one of a side route and an alternate route, wherein one of;

the at least one parameter provides for the selected map information to be tolerant of multiple errors in a starting region and a destination region of the predefined polyline, and

the at least one parameter provides for the selected map information to be tolerant of at least one error as a function of a class of a road; and

causing the navigation computer to generate a navigational instruction.

5. The method according to claim 4, wherein the at least one parameter provides for the selected map information to include a navigational instruction.

6. The method according to claim 5, further comprising:

formatting the navigational instruction to lead back to at least one of a destination via the alternate route and to the predefined polyline on one of a shortest route, a quickest route, and a most efficient route.
