Abstract
A navigation device is disclosed. In at least one embodiment, the navigation device includes a storage device to store map information; a processor to determine a route of travel based upon a current position of the navigation device and an input or selected destination position; and a display to display the current position on the map information corresponding to the determined route of travel, the display displaying zoomed-in display of the map information upon the processor determining that a decision point is within a threshold distance of the current position of the navigation device.
Claims16
A navigation device, comprising:
- a storage device, in the navigation device, to locally store vector-based map information;
- a processor, in the navigation device, configured to determine a route of travel based upon a current position of the navigation device within the locally stored vector-based map information and a destination position within the locally stored vector-based map information, the processor configured to determine at least one action point on the route of travel, the at least one action point being a point along the route of travel where more than one route action is available;
- and
- a display, in the navigation device, configured to display the current position in a graphical representation of the locally stored vector-based map information and to display the determined route of travel, the display being further configured to display additional information from the locally stored vector-based map information upon the processor determining that the at least one action point is within a threshold distance of the current position of the navigation device.
A method, comprising:
- locally storing vector-based map information in a storage device of a navigation device;
- determining a route of travel based upon a current position of the navigation device within the locally stored vector-based map information and a destination position within the locally stored vector-based map information;
- and
- determining, by a processor in the navigation device, at least one action point on the route of travel, the at least one action point being a point along a route of travel where more than one route decision is available;
- displaying, on a display of the navigation device, the current position in a graphical representation of the locally stored vector-based map information corresponding to the determined route of travel, the displaying including additional information of the map information upon the processor determining that the at least one action point is within a threshold distance of the current position of the navigation device.
