Description

201027040 VI. Description of the Invention: [Technical Field of the Invention] This disclosure relates to a navigation device and to a method for confirming a travel path from a first location to a second location. Portable navigation devices (so-called PNDs), in particular for PNDs containing Global Positioning System (GPS) signal reception and processing functionality. More generally, other embodiments are directed to performing navigation Software to provide path planning and preferably also provide any type of processing device for navigation, functionality. [Prior Art] A portable navigation device (PND) including GPS (Global Positioning System) signal receiving and processing functionality is well known and widely used as an in-vehicle or other vehicle navigation system. Such devices are very useful when the user is unfamiliar with the path they are navigating to their destination. However, it takes time to confirm the travel path to the destination. To calculate the "best" or "best" path, the average speed of each segment along a possible travel path is typically used. As the distance to the destination increases, the time for the travel path will generally increase. The user of the navigation device cannot tolerate waiting for the navigation device to confirm the travel path. Although the use of faster processors in the navigation device can increase the speed at which travel paths are calculated, faster processors are more expensive and tend to increase the cost of producing navigation devices. SUMMARY OF THE INVENTION According to an exemplary embodiment, a method for travel path validation in a navigation device is disclosed. The method includes using a 137328.doc 201027040 processor to confirm a travel path from a first location to a second location based at least in part on an average speed profile for at least one type of way along the travel path Map information. The method further includes displaying the map information on a display device of the navigation device. Another exemplary embodiment of the present disclosure is directed to a navigation device. The navigation device includes a memory resource that stores average speed data for a plurality of types of roads and average speed data for a plurality of paths. The navigation device includes one of map information confirming a travel path from a first location to a second location based at least in part on the average speed profile for at least one of the plurality of types of roads along the travel path processor. The navigation device also includes a display device for displaying the confirmation map information. The advantages of the specific embodiments are set forth below, and additional details and features of each of these specific embodiments are defined in the accompanying claims and in the following detailed description. [Embodiment] An exemplary embodiment of the present disclosure will now be described with particular reference to a PND. However, it should be noted that the teachings of the present disclosure should not be limited to PNDs but are instead commonly applied to any type of processing device configured to execute navigation software to provide path planning and navigation functionality. Therefore, it should be understood that in the context of the present application, a navigation device is intended to include (without limitation) any type of path planning and navigation device regardless of whether the device is embodied as a PND or built into one of the vehicles. A navigation device or a computing resource that does perform path planning and navigation software (such as a desktop or portable personal computer (PC), a mobile phone, or a portable digital assistant (pda)). 137328.doc -5- 201027040 It should also be clear from the following that the teachings of the present disclosure are even effective in the case where one user does not seek guidance on how to navigate from one point to another, but only in the case of a view with a given position. Sex. In such a situation, the "destination" location selected by the user does not have to have a corresponding starting position that the user desires to start navigation, and therefore the reference to the "destination" location or indeed a "destination" view should not be used herein. Interpretation means that a path must be generated, travel to the "destination" must occur or indeed a destination is required to specify a corresponding starting position. With the above limitations in mind, the figure illustrates an example view of a Global Positioning System (GPS) that can be used by a navigation device. Such systems are known to us and used for a variety of purposes. In general, GPS is a satellite radio-based navigation system capable of confirming continuous position, speed, time, and direction information for an unlimited number of users in some instances. This GPS, formerly known as navstar, is incorporated into a number of satellites that orbit the Earth in a very precise manner. Based on these accurate orbits, GPS satellites can relay their location to any number of receiving units. The GPS system is implemented when a device (especially equipped to receive GPS data) begins scanning the RF of the GPS satellite signal. After receiving a radio signal from a Gps satellite, the device confirms the exact location of the satellite via one of a plurality of different conventional methods. In most instances, the device will continue to scan the signal until it acquires at least three different satellite signals (note that the location is not normal, but can be confirmed, of which only two signals are confirmed using other triangulation techniques). Geometric triangulation is implemented and the receiver utilizes the three known locations to confirm its own two-dimensional position relative to the satellites. 137328.doc 201027040 This can be done in 6 ways. In addition, obtaining a fourth satellite signal will allow the receiving device to calculate its three dimensional position by the same geometric calculation in a known manner. The position and speed data can be updated instantly by an unlimited number of users on a continuous basis. The GPS system is generally indicated by reference numeral 100 as shown in FIG. A plurality of satellites 120 are in orbit around the earth 124. Each satellite: 2〇 is not necessarily synchronized with the orbits of other satellites, but it is actually possible to be asynchronous. Display GPS receiver 14〇

The pirate receives the spread spectrum GPS W satellite signal 160 from various satellites 120. The spread-spectrum signal (10) continuously transmitted from each satellite 120 utilizes a highly accurate frequency standard that is completed using a very accurate atomic clock to call its data (4). Each satellite of the transmitting (10) portion transmits 12 指示 to indicate that the particular satellite is 12〇 The flow of data. Those skilled in the art will appreciate that the Gps receiver device 14 typically obtains a spread spectrum Gps satellite k from at least three satellites of the (10) receiver device 14G to calculate its two-dimensional position by triangulation. The resulting acquisition of an additional signal from the signal 160 of a total of four satellites 120 allows the GPS receiver device 14() to calculate its three-dimensional position in a known manner. 2 is an illustrative representation of an electronic component of a navigation device in a block component format in accordance with one example of the present disclosure.

A unit of microprocessor 21, power supply, memory system 23, etc.). "Hai navigation device 200 can be located on an arm 292, which itself can be secured to a vehicle auxiliary instrument panel/window/etc. using a suction cup 294. This arm 292 is an example of a docking station that can be coupled to one of the navigation devices 200. As shown in Figure 4b, the navigation device 200 can be coupled or otherwise coupled to one of the arms 292 of the docking station by latching the navigation device 200 to, for example, the arm 292. The navigation device 2 can then be rotatable on the arm 292 as indicated by the arrow of the servant. "To release the connection between the navigation device 2 and the docking station," for example, the button can be pressed. One of the navigation device 2 buttons. Other equally suitable configurations for coupling and decoupling the navigation device to a docking station are well known to those skilled in the art. Referring now to Figures 5a through 5i, a series of screen shots from a navigation device 2A will be described. The navigation device 200 has a touch screen interface for displaying information to a user and for receiving input from the user to the device. The screen displays to the user an illustrative example of a destination location entry procedure in which the user's home location has been set to the European Patent Office's Hague office and it is desirable to navigate to the street name and 137328.doc -15- 201027040 The street number of the building number in Amsterdam, the Netherlands. When the user turns on their navigation device 200, the device (in a known manner) obtains the GPS location and calculates the current location of the navigation device 2〇〇. As shown in FIG. 5a, the user is then presented with a display 34A that displays the local environment 342 in which the navigation device 200 is positioned in a pseudo three-dimensional display and displays the local environment in an area 344 of the display 340. A series of • Control and status messages. By touching the display of the local environment M2, the navigation device 2 switches to display (as shown in FIG. 5b) by which the user can specifically input a series of virtual buttons 346 of a destination to which he desires to navigate. . By navigating to the virtual button 348, the navigation device 2 switches to display (as shown in Figure 5c) a plurality of virtual buttons associated with different categories of selectable destinations. In this example, the display displays a "home" button that, when pressed, sets the destination to the store location. However, in this example, since the user is already in their home location (ie, the (10)0 office in The Hague), selecting this option will not cause the path to be generated. If the "Special Favorite" button is pressed, it reveals a list of the destinations previously stored by the user in the navigation device 200, and if the destinations of these destinations are subsequently selected, the destination of the path to be calculated is Set to select the previous storage destination. If the "Recent Destination" button is pressed, it is not displayed in the memory of the navigation device 2 and a list of selectable destinations that the user has recently navigated to. The selection of one of the destinations located in this list sets the destination location for this route to the selection (pre-tour) location. If the "point of interest" button is pressed, the revealing user 137328.doc -16- 201027040 may choose to navigate to a plurality of locations (for example, pre-stored in the location as the user of the device may wish to navigate to) Many options in any of the devices, for example, cash machines, gas stations or tourist attractions. The "Arrow" Mold Virtual button opens a new menu for one of the additional options, and the "Address" button 35 starts a program in which the user can enter the track address of the destination to which he wishes to navigate. Because in this example the user knows the street address of the destination that he or she wishes to navigate to, it is assumed that the operation (by touching the button displayed on the touch screen) the "address" button 'is therefore (as shown in Figure 5d) ), presenting the user with a series of address input options, in particular, by "city center", by "postal area code", by "intersection or handover" (for example, the junction of two roads) and borrowing Used by "street and house number" for address input. In this example, the user knows the destination address and house number of the destination and thus selects the "Street and House Number" virtual button 352, so that the name of the city to which the user is expected to navigate is then presented to the user as shown in Figure 5e. A prompt 354, the user can select a flag button 356 of the country in which the location is required, and a virtual keyboard 358 that can be operated by the user to enter the name of the destination city if needed. In this example, the user has not navigated to the location within Rijswijk and Amsterdam, and the PND thus additionally provides the user with a list 360 of selectable domain cities. The user in this example desires to navigate to Amsterdam, and after selecting Amsterdam from the list 360, the navigation device 200 displays a virtual keyboard 362, one of which can be entered by the user, as shown in FIG. .doc -17· 201027040 A prompt 364 for the entry of the street name 364 and, in this example, a list 366 of selectable streets in Amsterdam as the user has just navigated to one of the streets in Amsterdam. In this example, the user desires to return to the track Rembrandtplein of his previous tour and thus select Rembrandtplein from the display list 366. Once a street has been selected, the navigation device 2 then displays a smaller virtual numeric keypad 368 and prompts the user via the prompt 370 to enter the number of the house in the selected street and the city to which it is desired to navigate. If the user has previously navigated to one of the house numbers in the street, the number is initially displayed (as shown in Figure 5g). As in this example, if the user desires to re-direct to Rembrandtplein No. 35, the user only needs to touch a "Complete" virtual button 372 displayed in the lower right corner of the display. If the user desires to navigate to a different house number in Rembrandt Square, all that is required to do is to operate the numeric keypad 368 to enter the appropriate house number. Once the house number has been entered, the user is asked in Figure 5h whether he or she expects to arrive at a particular time. If the user pushes the "Yes" button, it calls the estimated time to travel to the destination and advises the user that he should leave (or if he is late, should have left) his current location in order to arrive at his destination on time. The functionality of time. In this example, the user does not care about arriving at a particular time and therefore selects the "no" virtual button. Selecting the "no j button 374 causes the navigation device 2" to calculate the path between the current location and the selected destination, and displays the path as shown in FIG. 5A on the relatively lower magnification map displaying the entire path. 376. User tool 137328.doc -18· 201027040 may be pressed to indicate a "complete" virtual button 378 that is not satisfactory for the calculation path, the user may press to cause the navigation device 200 to calculate to the selected destination Another "find alternative" button 38 of the other path and a "detail" of a selectable option that the user can press to reveal a display of more detailed information about the current display path 376 is known. In this example, assume that the user is satisfied with the display path, and once the "Done" button 378 has been pressed, the user is presented with a pseudo three-dimensional view of the current starting position of the navigation device 200 as shown in FIG. The display depicted in FIG. 6 is similar to the display shown in FIG. 5a except that the display local environment 342 now includes a start location flag 384 and an anchor point indicator 386 indicating the next motion (in this example, left turn). . The lower portion of the display also changes and now displays the street name that currently locates the navigation device 2, the distance to the next motion (from the current position of the navigation device 2), and one of the types of next motion 388 And a dynamic display 390 to the distance of the selected destination, ie time. The user then begins its travel and the navigation device 2 updates the map by making a confirmation change in the location of the navigation device 200, and by making the user visually and optionally audibly navigated through the command Way to guide the user. According to various embodiments of the present application and as illustrated in FIG. 7, a portable navigation device is provided for use in a travel path confirmation method. The method includes using a portable navigation device in S1. One of the processors 21 identifies the map information for the travel path from a first location to a second location. The confirmation is based at least on the average speed data used for the road to the enchantment 137328.doc _19_ 201027040. In S2, the method further includes displaying the confirmation map information on a display device 240 of the navigation device 200. It should be noted that aspects of one embodiment of the present application have been described and will be described with respect to the method of the present application. However, at least one embodiment of the present application is directed to a navigation device 200 that includes a memory resource 230 containing average speed data for a plurality of types of paths and average speed data for a plurality of paths, at least in part Determining, according to an average speed profile of at least one of the plurality of types of paths along the travel path, a processor 21 〇 of the map information from one of the first locations to a travel location of the second location and for A display device 220 is displayed, wherein the display device 220 can be part of an integrated input and display device 29〇. Thus, such a navigation device 200 can be used to implement various aspects of the above-described methods as would be appreciated by those skilled in the art. Therefore, further explanation is omitted for the sake of brevity. After the user of the navigation device 200 inputs a desired destination as described above, the processor 210 starts to confirm from a first location (generally the current location of the user) to a second location (ie, a required destination). Travel path. The processor 210 validates the travel path using stored average speed data (e.g., stored in memory resources 23) for each type of way along the possible travel path. Examples of road types may include (but are not limited to) local asphalt roads, dirt roads, monuments, highways, two-lane streets, four-lane streets, toll roads, and the like. Each of the various types of roads is associated with average speed data. Thus, for example, a highway can be associated with an average speed of 88 KPH, while a two-line street can be associated with an average speed of 50 KPH. In an embodiment 137328.doc -20· 201027040 of the present application, the average speed of the roads of the average speed data type is not the average speed of any particular road along the travel path. The use of the average speed along the actual path of the travel path is more quickly and/or more effectively confirmed.

The processor 210 only needs to retrieve the average velocity data for each type of path along the travel path. Therefore, if the possible path of the trip includes three different road segments and three double-line street segments, the processor 210 only needs to draw two average speeds from the memory resource 230, that is, the average highway speed and the average speed of the two-lane street. Instead of one, the six separate average speeds for each segment. After confirming the travel route in this manner, the map information about the confirmed travel route is then displayed to the user on the display device 22 and the user can start traveling to the destination as explained above. After confirming the travel path in the manner described above, the processor may also confirm whether the revision of the travel path will result in a relatively short travel time from the first location to the second location. In a specific embodiment of the present application, the revised travel path is calculated using the storage average speed (4) of the actual road or section along the revised travel path. The average speed of (4) (4) can be used for all road sections along the travel route, but (10) along the travel route: the average speed of the two specific road sections can actually be (for example, "Ο·" cut brigade and road m, therefore, can be used Some of the other sections may have an average speed that is faster than the actual average speed of the road section. As explained above, the calculation is based on the average speed data of the second/: section. Because the travel route is longer and the nose is longer, the road is initially confirmed in the above manner. 137328.doc -21 · 201027040 The user can start traveling to the destination device 21 to confirm the revised travel. God, C, by the ballad, that is, the user does not have to know or know the calculation. If the use of the = average speed data along the revised travel path followed by confirmation - the shorter travel time of the revised travel path is used. And the processor 21G may modify the travel path and may control the revision of the map information (for example, instead of displaying the previously confirmed map information) on the display (4), thereby changing the travel path to the revised travel. path.
