Description

200930986 IX. INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates to an improved navigation apparatus and method. [Prior Art] A PLAY 1 (PND) including a GPS (Global Positioning System) signal receiving and processing component is well known and widely used as an in-vehicle navigation system. In essence, a modern PND includes: - a processor, memory Body (at least one of volatile memory and non-volatile memory 'and usually both), map data stored in the memory, a software operating system and (as appropriate) one of the executions Or a plurality of additional programs for controlling the functionality of the device and providing various features, - a GPS antenna by which satellite broadcast signals including location data can be received and the signals are conditioned to determine the current location of the device, Situation) an electronic gyroscope (gyr〇sc〇pe) and an accelerometer that generate signals that can be processed to determine the #front angular acceleration and linear acceleration, and that combine with the position information derived from the GPS signal to determine the device And thus the speed and relative displacement of the vehicle in which the device is mounted, the input and output components, 眚 丨 - k , „ ^ Examples include a visual display (which can be a touch A type of display to allow use of the user to turn in), one or more physical buttons to control the on/off operation or the speaker of the device, other features of the sorrow, for voice output (as appropriate) or Multiple solid squid connectors' by means of the entity or 127917.doc 200930986 can transmit power and optionally one or more data signals to and receive power from the device and, as appropriate, one or more Data signals, and - (as appropriate) one or more wireless transmitters/receivers to allow communication over mobile telecommunications and other signal and data networks (eg, Wi_Fi, Wi_Max GSM, etc.). The ability to open a route between destinations, which can be entered by a user of the computing device through a wide variety of different methods (eg, by postal code, street name, and number)' and can be well known for prior knowledge, Favorite or recently arrived destination. The pass f 'clear system is used to calculate the "best" or, best, route software between the starting address location and the destination address location based on the map data. Come to enable. "Best, or "best" routes are based on predetermined criteria and are not defined as the fastest or shortest route. The choice of route to guide the driver can be very complex and the route selected You can consider the existing = and dynamic and / or wirelessly received traffic and road information, historical information about the body and the drivers' factors for determining road alternatives:: preferences. In addition, the device can continuously monitor roads and traffic bars. Providing or selecting to change the rest of the trip due to changing conditions. Based on various technologies (for example, mobile power will be extended and information will be fed into the notification system. The onboard computer or car radio part of the vehicle mounted on the cutting tool is part of the portable system. The 铋& navigation device is also available, pda (personal navigation device), media broadcast 127917.doc 200930986 ❷ phone Or similarly' and in such cases, the conventional functionality of the system can be revealed by the software executing the route calculations and along the calculated route. In any case, the calculated 2-line user interacts with the navigation device (as appropriate, from the list of (4) routes) to select the desired route. Depending on the situation, the user may intervene or direct the route selection process, for example, by certain rules, roads, locations or standards. The PND route calculations form a primary function provided and navigation along this route is another major function. A visual and/or voice command is provided during the navigation along the calculated route to direct the user along the selected route to the end of the route, which is the desired destination. The reward usually displays map information on the screen during navigation, and such information is periodically updated on the screen so that the displayed map information indicates the current location of the device and thus the current location of the user or user's vehicle (if : Corrected for in-car navigation). The icon displayed on the screen usually indicates that the device position is 'centered' and also displays map information and other map features of the current and surrounding roads. In addition, depending on the situation, the navigation information may be displayed in the state bar above, below or on one side of the displayed map information. Examples of the navigation information include the distance from the current road that the user needs to select to the next deviation, and the deviation Property 'This property can be represented by a further representation indicating a particular type of deviation (eg 'left turn or right turn'). The navigation function also determines the content, duration, and timing of the voice commands that can be used to guide the user along the route. As you can see, simple instructions such as "100 m after left turn" require extensive processing and analysis. As previously mentioned, the user's interaction with the 127917.doc 200930986 device can be activated by the touch-controlled remote control, by sound, and by other means. Sound 9 starts or is calculated by any other suitable device. The more important work weight calculation: Automatic route under the Ganb Xi/Brother-=The user deviates from the road along the previously calculated route. It may be advantageous to indicate an alternate route, and the device can automatically recognize such conditions as appropriate, or - if the user actively causes the device to perform a route recalculation for any reason. It is also known to allow routes to be calculated according to user defined criteria; for example, the user may prefer a scenic route calculated by the device, or may wish to avoid any road that may occur, is expected to occur, or is currently experiencing a traffic jam. The device software will then calculate the various routes and prefer the route along its route including the highest number of points of interest (known as P0I), which are labeled (for example) with a view' or use to indicate positive on a particular road The stored information of the traffic conditions that occurred, sorted by the possible blockage or the level of delay due to blockage. Other route calculation and navigation standards based on p〇l and traffic information are also possible. Although route calculation and navigation functions are important for the overall utility of pND, it is possible to use the device purely for information display or "free driving", where only map information related to the location of the device is displayed, and it has not been calculated The route and the device are not currently performing navigation. This mode of operation is often applicable when the user is aware of the route along which the trip is to travel and does not require navigation assistance. 127917.doc 200930986 A more pressing requirement for modern touches is the need to update and/or correct map information stored in the device's memory as this information becomes obsolete. Of course, although you are on the banks... the main routes in the map information, highways, highways and other trunk roads are unlikely to change a lot over time, but the routes in the city centre are constantly being modified, enhanced or To improve traffic flow through the city or to prevent traffic from entering certain areas (because the shopping area is increasingly becoming a pedestrian-only area). US 6,253,151 describes a feature by which an end user of a two-air system using geographic data can easily report detected errors or inaccuracies or other problems in geographic data, such as poor quality route calculations 2 Guidelines. The final maker uses the user interface to indicate the errors detected, discrepancies or other problems. The navigation system includes a report T-type reporting program that operates in response to an indication of the final (4). Reporting process, collecting; daily 7F error, inaccuracy or other information and sending a report including the collected information to the geodatabase developer. Geodatabase Developers can use the information in the report to update the geodatabase. However, the above system is more concerned with ensuring that the centralized geographic or map database of the map data provider is as current and accurate as possible, as opposed to the correction of the current map data stored on the device. In a recent device (such as (10) 8 0720, which is available from the present applicant), a user interface menu structure is provided, whereby the user can = an error in the base map data, for example, by It is corrected by inputting specific road identification information, postal margin information or specific road segment information of 127917.doc 200930986 in the way of the user's desire to input the navigation destination before the binding calculation function. _ 曰 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Direction, on the system, speed _, (four) pedestrian limit type limit.

When the user makes such corrections, the corrections can be stored in the memory for later uploading to the towel-type suits, but more importantly, the corrections can be made locally in the context of the month of the month. Stored in the device and in the navigation and route calculations _ call it (4) to ensure that the operation is the most reliable device operation in the turn guide or in the / mode. For example, if the right specific road has an associated correction applied to it, the route calculation algorithm will only include that particular material in the route (if appropriate, this is corrected). Although the correction of map data locally in the PND or navigation system is known as 'subsequent uploading of correction data to a centralized server, but the correction facility provided on modern PNDs - the main disadvantage is that access is required subsequently A menu structure that identifies a particular route, road, or road segment. Obviously, entering A information while driving may be dangerous & and when driving (4) the route (in which the correction will be appropriate), the user often forgets the need for correction after the user has reached the destination, especially In cases where many corrections may have been required. It is an object of the present invention to provide a pND or navigation system, a method of operating the PND or navigation system, and a computer program for controlling a PND or navigation system that provides for correcting the location stored in the PND or navigation system 127917.doc -11 - ❹ ❹ 200930986 How to enhance the data. SUMMARY OF THE INVENTION According to the present invention, a method for correcting the map data stored in the -pND or the guide, soil, + ‘^ period threshold-(four)9 is provided.

The selection of the graphical indicator that is selectable by the other or similar user allows the correction to be stored in or removed from the memory, the correction including the travel restriction selected and removed (4) Identification of coherent roads. In the preferred embodiment, the selection of the graphical indicator for the or other such similar user causes a correction to be stored in or removed from the memory, and thereafter or The device causes display of map information including an earlier display of the associated track, wherein the previously displayed graphical indicator has been appropriately changed or removed to reflect the selected or removed limit, preferably the graphical indicator is In the form of a road sign, the basin is preferably displayed in a suitable manner along the main road along which the current route of the device is located. 0 127917.doc -12· 200930986 The graphical indication displayed in the 'best embodiment' The system is about the current main road where the device is located. In a modification of the invention, the map information is preferably displayed on the screen in a three-dimensional manner, and some of the perspectives are provided in the displayed information. In addition, it should be mentioned that the device may not be operating in a free-driving or navigation mode, but may be in a stationary route or in a map view mode in which a plan view of the enlarged map is displayed on the screen of the device or system, which covers the current The location, the location of the home or the favorite location or any location of the available map material on the device that is actually selected by the user. In this way, it is possible for the user to move around, zoom in and zoom out of the conventional map within the conventional map, and possibly cause the display of any particular point in the map data, whether or not the intersection appears in the calculation. On the outgoing route, and if a restriction is applied at the intersection, then a suitably selectable graphical indicator can be displayed on the screen along with the graphical representation of the map in accordance with the present invention. The selection of this graphical indicator causes the display of a calibration menu for other indicators as previously described. In the preferred embodiment, the selection of the graphical indicator and the selection of other user-selectable graphical indicators that are subsequently displayed not only cause one or more of the points to be approached or moved away from the main road. Storage or removal of a first correction of a main channel, and also causing storage or removal of a second correction, the second correction being dependent on the first correction of the selective storage or removal and based on the selectivity The first or plurality of second main roads are determined to be close to or away from the intersection of the main road.

[Embodiment] FIG. 1 illustrates an example view of a Global Positioning System (GPS) that can be used by a navigation device. These systems are known and used for a variety of purposes. In general, +GPS is a satellite radio based navigation system that is capable of determining continuous position, speed, time and, in some cases, direction information for an unlimited number of users. The GPS previously known as NAVSTAR incorporates a plurality of satellites that operate with the Earth in extremely precise orbits. Based on these precise orbits, GPS satellites can transmit their positional splits to any number of orders. 127917.doc •14·200930986. ::: The door is equipped with a GPS system when the device receiving the GPS data starts scanning the RF for the Gps 4. After receiving a radio signal from a GPS satellite, the device determines the exact location of the satellite via a plurality of different conventional methods. In most cases, the signal is scanned until it has obtained at least three different satellite signals = this is not the case 'but other triangulation techniques can be used and the position is determined by only two signals). After performing the geometric triangulation, the receiver uses its three known positions to determine its own two-dimensional position relative to the satellite. This determination can be made in a known manner. In addition, obtaining the fourth satellite signal will allow the receiving device to calculate its three-dimensional position in a known manner by the same geometric calculation. The position and speed data can be continuously updated in real time by an unlimited number of users. As shown in Figure 1, the GPS system is generally indicated by the reference numeral 1〇〇. A plurality of satellites 120 are in orbit around the earth 124. The orbit of each satellite is not necessarily the same as that of other satellites, and it is likely to be different. The GPS receiver 140 is shown to receive the spread spectrum (four) satellite signals from various satellites m. Spread-spectrum satellites continuously transmitted from each satellite 120 utilize a highly accurate frequency standard achieved by extremely accurate atomic clocks. Each satellite 120 transmits a data stream indicative of its particular satellite 120 as part of its data signal transmission 160. Those skilled in the relevant art should understand that the GPS receiver device i4〇 typically obtains the spread spectrum GPS satellite signal 16〇 from at least three satellites 120 for the sinus GPS receiver device 140 to calculate its two-dimensional position by triangulation 127917. .doc -15- 200930986 Set. The acquisition of an additional signal (which causes the number 160 from a total of four satellites) permits the GPS receiver device 14 to calculate its three dimensions in a known manner.

504' includes a display as previously described. As can be seen from the screen screens, 'display map information in 3D mode, where the horizon 506 is usually displayed, and the displayed map information (which is generally based on 2D map data stored in the device memory) is digitally adjusted to provide A perspective view of the user's imaginary view, as can be seen in screens 500 and 504, should be mentioned, the screens 500 and 504 are merely illustrative and generally display much more detailed information, especially When operating in navigation mode. However, in the simple unintentional screen shot shown, a virtual road sign 508 indicating a certain limit is displayed, in which case this limit applies to the current main road 5 and may be applied after the main road intersection 518. Then the main road 516. As will also be seen from Figure 5, the intersection point 518 is basically the point where the various main roads 51, 512, 514, 516 meet. Of course, the main roads 51〇, 516 and 512, 514 may in fact be the same road, but for the purpose of illustrating the present invention, independently refer to the main roads 0. In the screen face 500, the device is traveling along the main road 510, and The virtual identification 5 〇 8 including the graphical indicator indicating that the restriction of the upcoming main road 516 is not shown is closest to the intersection and adjacent to the main road 510. In the figure, graphical indicator 508 shows the user that the upcoming road is a one-way road along which the user will be allowed to travel in the current forward travel direction. ^ Because the first correction of the base map data has been stored = in the device memory 'or the basic map data includes some indication of the travel along the opposite lane, the specific entry is limited to a specific direction, so there is This limit may be graphically displayed. 127917.doc •24· 200930986 ❹

If this indication is incorrect, whether the correction of the basic map material or the previous correction applied to the basic map material is now obsolete, the displayed virtual identifier 508 is incorrect. In this case, the user can select the logo by touching the graphical indicator portion of the logo, thus displaying a number of other graphical indicators 520-532 indicating different entry restrictions. This honour allows the user to select the appropriate limits that can be applied to the particular route that will be available after the handover. In screen face 502, graphical indicator 522 is selected to indicate that the only possible travel direction available after intersection 518 is along trunk 514, i.e., a right turn. Thus, upon selection of the graphical indicator 522, the display returns to display displaying the map information, as shown in the screen 504, the identification 5 已 8 already has an appropriate graphical indicator that is corrected based on the selection made. section. The selection of graphical indicator 522 causes one or more background processing tasks to be completed. First, the device immediately returns to the display of the map information based on the current or previously recorded device location. In addition, the display virtual identification is corrected or may be removed (as shown in the screen 504 if the previously applied correction was reversed. Additionally, the correction being applied or removed causes a specific The storage or removal of a particular correction or update of the current and/or upcoming main road causes the correct virtual identification to be displayed not only at the same-way as shown adjacent to the screen 5(10) or 5〇, but also when the user is Along with the trunks 512, 514, 516 after the intersection, the brigade has applied restrictions to the one or has removed the appropriate virtual logo from the one. The reader will understand and combine The virtual information displayed on the map information is about 127917.doc -25- 200930986 = the way of the main road, the way to correct this (etc.), and the way in which it can be applied and then understand the correction. Various combinations are possible, but this It is different, 'and is easy to export and is undoubtedly within the scope of the present invention.

Although not shown in FIG. 5, virtual identification 508 may be replaced or enhanced by additional graphical indicators displayed in the depiction defining a particular road 510-5. Such indicators may be in the form of simple arrows, (iv) along a particular travel limit' or may be in the form of a color representation indicating the type of restriction along the other lane at the appropriate location. For example, instead of or in addition to the virtual identification 508, the graphical indicator portion of the identification may be graphically displayed at an appropriate scale in the depiction defining the main roads 510, 516.
