Navigation terminal, navigation method and remote navigation service system

Abstract: A navigation terminal, a navigation method, and a remote navigation service system are provided. The navigation method includes receiving a navigation command input by a user; starting a satellite positioning unit to determine current position information of a vehicle; sending the navigation command and the current position information of the vehicle to a remote navigation service system through a communications interface; receiving a navigation indication sent back by the remote navigation service system through the communications interface; and presenting the navigation indication to the user for navigation. The navigation method further includes photographing a road scene in front of the vehicle, where the road scene is displayed on a display screen of a man-machine interface, and the navigation indication includes a driving direction indication, and the driving direction indication is superimposed on the road scene for navigation.

Automatic creation of scenic tours using points of interest

Abstract: A method is provided for presenting audio information related to scenic points of interest (POIs) to a user traveling along a predetermined route. The predetermined route is guided by a navigation device for providing audio navigation announcements that include turn-by-turn directions to the user. The predetermined route is defined between the starting location and a destination that includes scenic POIs. Audio navigation announcements are output to the user for selectively guiding the user along the predetermined route. An active region around each POI while traveling along the predetermined route is used to identify a current POI. Audio POI information is reproduced relating to the current POI while the user is within the active region of the current POI. Audio POI information reproduced to the user is selectively scheduled at a time not conflicting with the audio navigation announcements output to the user.

GPS equipped devices that utilize geographical navigation bundles

Abstract: A method for providing and utilizing navigation data can include identifying a grid that includes a plurality of geographical regions. Each geographical region can have an associated navigation data set which includes street level mapping data. Linking references for each geographical region can be defined. Geographical navigation bundles can be identified that conform to an OSGi compliant framework. Each bundle can correspond to one of the geographical regions and can include a navigation data set and a manifest file. The manifest file can include a version, date, and the linking references. A GPS equipped device can dynamically install and activate the geographical navigation bundles. The GPS equipped device can perform at least one navigation process based upon the navigation data set. The GPS device can predict when new navigation data is needed and can automatically acquire suitable geographical navigation bundles in response to these predictions.

Display of navigation limits on an onboard display element of a vehicle

Abstract: A method of displaying navigation limits for a planned travel route of a vehicle is presented here. The method calculates estimated navigation limits for the vehicle using an onboard subsystem of the vehicle, where the estimated navigation limits represent self-assessed navigation accuracy of the vehicle relative to the planned travel route. Contracted navigation limits are acquired for the vehicle, where the contracted navigation limits represent specified navigation accuracy of the vehicle, relative to the planned travel route, as mandated by a third party navigation controller. A navigation display is rendered on an onboard display element such that it includes graphical representations of the planned travel route, at least one of the estimated navigation limits, and at least one of the contracted navigation limits.

Navigation method and system having improved arrival detection function for large scale destination

Abstract: A navigation system guides a user to a destination with an improved arrival detection capability when the selected destination is a large facility or a natural place that occupies a relatively large area. When a particular destination is specified by the user, the navigation system calculates a route to the destination based on the address of the specified destination. The navigation system also checks whether the specified destination is associated with polygon data. When the specified destination is associated with the polygon data, the navigation system creates an arrival detection start range. After reaching the arrival detection start range, the navigation system detects the arrival at the destination when any part of the polygon of the destination comes within an arrival detection range of the navigation system.
