Abstract

1. Способ, содержащий этапы, на которых: ! определяют маршрут перемещения на основании ввода пункта назначения перемещения в навигационное устройство; ! отображают картографическую информацию, извлеченную из первой карты на навигационном устройстве, передавая определенный маршрут; ! принимают информацию о текущем положении относительно перемещения по определенному маршруту; ! автоматически переключают отображаемую картографическую информацию на отображение относительно более детальной картографической информации, извлеченной из второй карты, при определении, что текущее положение по маршруту вступает в область, которая покрывается упомянутой второй картой, предлагающей упомянутую относительно более детальную картографическую информацию, чем первая карта. ! 2. Способ по п.1, в котором этап, на котором автоматически переключают отображаемую картографическую информацию, сопровождается этапом, на котором переносят маршрут, причем маршрут, передаваемый на отображаемой картографической информации, извлеченной из первой карты, автоматически переносится на отображаемую относительно более детальную картографическую информацию, извлеченную из второй карты. ! 3. Способ по п.1 или 2, в котором первая карта и вторая карта сохраняются на запоминающем устройстве в навигационном устройстве. ! 4. Способ по п.1, в котором для текущего положения извлекается уровень картографической детализации положения на карте, представляющий собой по выбору одну из трех категорий уровня картографической детализации, включающих в себя категории, указывающие каждое из: фактически нет покрытия, относительно высокое покрытие, и от 1. A method comprising the steps of:! determining a travel route based on inputting a travel destination to the navigation device; ! displaying cartographic information extracted from the first map on the navigation device, transmitting a specific route; ! receive information about the current position regarding movement along a specific route; ! the displayed cartographic information is automatically switched to displaying relatively more detailed cartographic information extracted from the second map, when it is determined that the current position along the route enters the area that is covered by said second map offering said relatively more detailed cartographic information than the first map. ! 2. The method according to claim 1, in which the step of automatically switching the displayed cartographic information is accompanied by the step of transferring the route, the route being transmitted on the displayed cartographic information extracted from the first map is automatically transferred to the relatively more detailed cartographic displayed information extracted from the second card. ! 3. The method according to claim 1 or 2, in which the first map and the second map are stored on a storage device in the navigation device. ! 4.

Claims

1. A method comprising the steps of:

determining a travel route based on inputting a travel destination to the navigation device;

displaying cartographic information extracted from the first map on the navigation device, transmitting a specific route;

receive information about the current position regarding movement along a specific route;

the displayed cartographic information is automatically switched to displaying relatively more detailed cartographic information extracted from the second map, when it is determined that the current position along the route enters the area that is covered by said second map offering said relatively more detailed cartographic information than the first map.

2. The method according to claim 1, in which the step of automatically switching the displayed cartographic information is accompanied by the step of transferring the route, the route being transmitted on the displayed cartographic information extracted from the first map is automatically transferred to the relatively more detailed cartographic displayed information extracted from the second card.

3. The method according to claim 1 or 2, in which the first map and the second map are stored on a storage device in the navigation device.

4. The method according to claim 1, in which for the current position the level of cartographic detail of the position on the map is extracted, which is optionally one of three categories of the level of cartographic detail, including categories indicating each of: virtually no coverage, relatively high coverage, and relatively low coverage.

5. The method according to claim 4, which further comprises using the stored categories of level of detail for information about the current position when determining whether relatively more detailed cartographic information can be displayed by comparing this level with the level of detail assigned to any another card stored on the device’s storage device and on which the current position is located.

6. The method according to claim 5, in which the stored decision rules are used to determine which map should be used to display cartographic information in the case when the corresponding levels are equal during comparison.

7. The method according to claim 1, in which the displayed map information and relatively more detailed map information include at least one of the traffic and the condition of the road.

8. A navigation device made with the possibility of implementing any of the methods that are described in paragraphs.1-7.

9. A computer-readable medium comprising program segments when executing a navigation device on a processing device, prompting the navigation device to implement the method according to any one of claims 1 to 7.
