Description

Personal navigation device and method for generating navigation instructions with reference to avoidance points

technical field

The present invention relates to a personal navigation device and its method, in particular to a personal navigation device and its method which can avoid the avoidance point selected by the user when a navigation instruction is generated.

Background technique

Navigation devices with built-in Global Positioning System (GPS) are not only well known but also widely used in car navigation devices. The general function of the navigation device includes providing a map database for generating navigation instructions on the display of the navigation device. The navigation device is usually fixed on the dashboard or embedded into the dashboard.

The term "navigation device" refers to a device capable of navigating a user to a predetermined destination. Navigation devices have internal systems for receiving location information, such as GPS receivers, or can only be connected to receivers that can receive location information. The navigation device itself can calculate the navigation route by itself, or connect to a remote server, and the remote server can calculate the navigation route and provide navigation information to the navigation device, or the navigation device cooperates with the remote server to complete the calculation of the navigation route. The personal GPS navigation device is not permanently fixed on a vehicle but can be disassembled or loaded on any vehicle at any time. Therefore, the personal GPS navigation device is equipped with full functions, that is to say, the personal GPS navigation device includes a built-in GPS antenna, Navigation software and maps, so navigation paths can be depicted and displayed.

The personal navigation device strives to find the most appropriate path to guide the user, so that the time required for the user to move from the starting point to the destination is minimized. However, users who are familiar with a particular area often have their own personal preferences for areas, roads, or intersections they want to avoid. For example, a personal navigation device may direct the user to turn left at the end of the road, but the user knows that a right turn is clearly the better choice. The discrepancy between the navigation instructions and the user's own perception of the area will cause user frustration in use and, if such problems occur frequently, may cause the user to abandon the use of the personal navigation device.

In addition to avoiding specific locations during each navigation, users may want to avoid certain areas, roads, or intersections only during certain times of the day, such as rush hour traffic.

The memory 30 stores a map database 32 , a route planning software 34 and an avoidance point data 36 . The map database 32 includes map data and POIs.

In the present invention, the user can create avoidance points, and each avoidance point has corresponding location information, such as latitude/longitude data, which section of the road or highway, a specific intersection, or intersection. Of course it is also possible to avoid certain road directions at certain intersections. For example, a user may prefer to turn left (or turn right) at a particular intersection on a road, although the destination can be reached in other directions.

In addition, the avoidance points can also be adjusted according to the time difference. For example, some avoidance points can be avoided during rush hours of traffic, and these avoidance points are the avoidance point data 36 stored in the memory 30 . The user can input these avoidance points through the user interface 20 of the personal navigation device 10 , or import existing avoidance points from a server or a computer. The GPRS modem 16 or other similar communication devices can be connected to a server via the Internet to download the avoidance point, and the USB port 22 can also be used to import the avoidance point from the computer to the avoidance point data 36 of the memory 30 . When the user imports avoidance points to the personal navigation device 10, the user can choose to import all avoidance points, or only choose to import the avoidance points in a specific area, or only import the ones in the directory selected by the user. Get out of the way.

After the avoidance point is stored in the avoidance point data 36 of the memory 30 , the user can input a destination through the user interface 20 of the personal navigation device 10 to make the personal navigation device 10 plan a route navigation instruction. Then, the route planning software 34 will generate a route avoiding the avoidance points selected by the user. If one or more avoidance points cannot be avoided, the path planning software 34 will issue a warning through the display 12 or speaker 24 .

The present invention provides many benefits to the user. For example, users who regularly commute to work or school will want to avoid heavily congested roads or intersections, or school areas on the way to their destination, or areas under construction, etc. Commercial truck drivers will want to avoid roads, bridges, tunnels, or intersections with height restrictions, weight restrictions, and hazard restrictions. Users who pay special attention to security, such as the elderly, drivers who drive alone, or pedestrians, will want to avoid areas with known poor security or high crime rates. Additionally, other users may want to avoid tolled roads, or other tolled paths.

Please refer to FIG. 2 , which is a flowchart of a method for avoiding an avoidance point when the personal navigation device 10 generates a navigation instruction according to the present invention. The steps of the method flow chart are detailed below:
