Wi-Max GSM and its similar). The utility of 卿 主要 is mainly manifested in its ability to determine the route between the starting point or the destination, and the destination can be entered by various methods of the user of the computing device, for example, by postal code, street k name and number 1 The well-known, favorite, or recently-intended purpose of the previous material = usually 'PND is used to calculate the starting address bit based on the map data.' The best " or, between, the best, the route Software to enable. The "best" or "best" route is based on predetermined criteria and is not the shortest or the shortest route. The choice of the route along which the driver is guided can be very complex and the route can be considered and (4) =: due to: historical information on road speed and the driver's own preference for determining the road traffic. In addition, the device can continuously monitor the road and provide or choose to change the route due to changing conditions. The route will be traveled under (4). Instant traffic based on various technologies (such as phone calls, fixed cameras, GPS fleet tracking) is being used to identify traffic delays and feed information into the notification system. The navigation device can usually be mounted on the instrument panel of the vehicle, but it is also part of the onboard computer or car radio. The navigation device can also be a system (part of), such as 'pDA (personal navigation device), media:, mobile phone or the like, and in this case: installed on the device to perform route calculation and along Refers to the calculated route = extending the general functionality of the portable system. In any case, the spider route interacts with the navigation device (as appropriate, from the list of proposed 2 lines to the desired route. Depending on the situation, user = 127909.doc 200930978 ❹ ^Pre- or 51 route selection process, for example, by specifying that certain routes, roads, locations or standards should be avoided or to be followed for a particular trip. Routes form a primary function provided and navigate along this line to another The main trick is to provide visual and/or voice commands along the calculated route navigation gate PND to direct the user along the selected route to the end of the route, which is the desired destination. Displaying map information on the screen during navigation, such information is updated on the screen, so that the displayed map information is related to the current location of the device and thus to the current location of the user or user's vehicle (if The device is being used for in-vehicle navigation. The icon displayed on the screen usually indicates the current device location and is centered, and also displays map information of the current and surrounding roads. The map features. In addition, depending on the situation, the navigation information may be displayed on the top, bottom or 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. The nature of the deviation from the 'this property can be represented by a step-by-step diagram indicating the specific type of deviation (such as 'left turn or right turn _). The navigation function also breaks the content, duration and timing of the heart 7 The instructions can be used to guide the user along the route. As can be appreciated, simple instructions such as "(10)m turn left" require a lot of processing and analysis. As mentioned earlier, the user disk can be borrowed. By touch screen, or otherwise or by a steering wheel women's remote control, by sound activation or by any other suitable method. The more important function provided by the device is the recalculation under the following conditions: 127909 .doc 200930978 - During the navigation along the previously calculated route, the user deviates from the route, • the immediate traffic condition indicates that the alternative route will be more advantageous, and the device It is sufficient to automatically recognize these conditions, or - the right user actively causes the device to perform route recalculation for any reason. ° It is also known to allow calculation of routes by user-defined criteria, for example, users may prefer The scenic route calculated by the device. 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 beautiful views Other P0I-based route calculation and navigation standards are also possible. Although the route calculation and navigation functions are important for the overall utility of the PND, it is possible to use the device purely for information display or "free driving", which only shows Map information related to the current device location, and the route has not been calculated and the device is currently not performing navigation. This mode of operation is often applicable when the user is aware of the route along which the trip is to be made. As mentioned, 'PND can be used in personal or business capacity, the latter use is more suitable for commercial driving activities, such as courier and other delivery services. In addition, where pND is used in cars for personal and business use, national governments or other national authorities typically require users to keep records of all pure business processes for tax purposes. In addition, for vehicles owned by a company employee or a number of different company employees, the 127909.doc 200930978 and the general purpose of the vehicle are used to determine the total cost of the vehicle and The benefits are important for business and for determining the proper use of the vehicle.

[Embodiment] FIG. 1 illustrates a real I 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, ‘1 GPS is a satellite-based 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.

Previously known as navstarmps, there are multiple satellites that operate with the Earth in extremely precise orbits. Based on these precise orbits, GPS satellites can pass their positional splits to any number of receiving units. A GPS system is implemented when a device that is specifically equipped to receive GPS data begins scanning radio frequencies for GPS satellite signals. After receiving a radio signal from a GPS satellite, the device determines the exact location of the satellite via one of a plurality of different conventional methods. In most cases, the device will continue to scan the signal ' until it has obtained at least three different satellite signals (note that it is often not only possible to use other triangulation techniques to determine position by only two signals). After performing the geometric triangulation, the Weiner uses 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 homo-geometric calculation. Location 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 〇〇. A plurality of satellites 120 are in the orbit of the Earth 124. The track of each satellite is 127909.doc •13- 200930978 The track is not necessarily synchronized with the orbit of other satellites 120, and is actually likely to be different. GPS receiver 140 is shown to receive spread spectrum gPS satellite signals from various satellites 12A. The spread spectrum satellite signal 16 continuously transmitted from each satellite 120 utilizes a highly accurate frequency standard achieved by an extremely accurate atomic clock. Each satellite 120 transmits a data stream indicative of its particular satellite 120 as part of its data signal transmission. Those skilled in the art will appreciate that the GpS receiver device 140 typically obtains a spread spectrum GPS satellite signal 160 from at least three satellites 12 for the GPS receiver device 14 to calculate its two dimensional position by triangulation. The acquisition of an additional signal, which causes a signal 160 from a total of four satellites, permits the GPS receiver device 140 to calculate its three dimensional position in a known manner.

These options are (in top-to-bottom order) turn the device on and off, "turn at the intersection", arrive/depart Land, "arrival/departure favorite", "arrival/departure to new destinations, and the option to stay more than 15 minutes more or less can form this set of options related to the free-driving mode, and among these options Any - or more can be > into the set of options associated with the free-driving mode and is considered to be a claimable aspect of the invention. All of the options shown in Figure 8 are shown as selected, and if so For the user to accept, the selection of the "next" graphic 526 causes a display of another list of options for the description of the information in the navigation mode, as represented in Figure 9. Again, the option list 532 is displayed, These options are events that are documented after they occur. All the options shown in the figure are selected and in order "new planned route", "non-compliance planned route" And "arrival One of the additional possible events not shown in the figure is "Recalculation of Routes", but of course 127909.doc •23· 200930978 can be included in the “New Planning Routes” option. The present invention, by which the present invention may be implemented, allows the creation of a virtual travel distance of a travel (planned or unplanned) route classified according to a particular use (e.g., for example, an entertainment plan). Reviewing the material event. The invention contains an event-based event. The implementation of the documentary strategy is only recorded when the event is caused.

Sigh. An event can be defined as a state change in the settings within the detail and a state change in the space and time domain. Examples of possible events include: • Deviation from previously planned routes Any user-actuated or automated route recalculation Every turn or route change opening and closing device at any intersection • Change from personal activity to business activity Change back • Leave or reach the location of the home • Power on and off the device • Leave or arrive at the favorite location • Leave or arrive at a new destination stored in memory • The device is stationary for more than a predetermined amount of time For the sake of simplicity, distinguish between two Travel mode is useful: • In free-ride mode, the navigation device is passively used to view the current position on the map. • In the planning route mode, the user enters the target destination to navigation 127909.doc •24· 200930978 In-device “The route calculation is performed by the device, and as the case may be, the user performs a list of possible S-calculated routes. The choice of one, and the device initiates navigation of the route or the selected route. As mentioned above, 'users can change the settings of the device to "Enable in the Free. Driving Recording mode. Under this setting, the device will start as soon as it is turned on. Record. In the "Planning Routes", it is also considered to be planning. And each new route to the destination is a valid event. A set of appropriate events to achieve a record of each travel mode is now described. ® In this case, it is assumed that the PND is being used passively, that is, in the free drive mode, and only the current position is displayed on the screen of the map information. Ideally, the device preference is that once the PND is turned on, it is enabled "documentation" mode in free driving. With this setting, the device will record the location and time when the following preferred events occur: • When the device is turned on and off, when the (business or personal) activity is specified, ^ # arrives in the original or recorded location. In the case of one (such as a new destination or a favorite place), the road is deviated on either line. The road intersection is the current road. For example, if it is the target destination, if N is the vehicle ( And the initial position of the device) and τ

The mode is recorded in the free mode. The user turns on the device; and " in " is enabled. The user specifies that the purpose of the trip is business. 127909.doc •25- 200930978 The purpose is for personal purposes and then begins to drive. After reaching the target destination τ, the user sets the activity to personal use and turns off the device. For the log of all events as described above, at the end of this journey, we will have the following journey log entries in the journey log file: . Enter free drive mode - [date/time] • At position N (total: 400 km) ) Opening device - [date/time or volume a] Activity setting to business use: total: 500〇km-[date/time or increment b] θ © turn left at 0 (N-〇·· 5 km, Total: 5005 km)-[曰期/time or increment c] Turn right at P (Ο-P: 1〇km, total: 5015 km)-[曰期/time or increment d] Left at Q Turn (PQ ·· 5 km, total: 5020 kmH曰 period/time or increment e) Turn right at R (QR: 1〇km, total: 503 0 km)-[曰期/时间戍.

However, the user can request this log to compress the log from 127909.doc •26·200930978 to a much smaller planned route log format. This compression is based on one Algorithm, the algorithm actually contains the calculation of the imaginary route between the N and T between the N and T and optionally at any of the intersections, P, Q, ruler and 8 and N4T. And the log file between these routes and the turns; the case is continuous and the adjacent segments are compared to establish the most concentrated ambiguity. For example, 'replace the route segment indicated in the log file. The algorithm is effective in determining the minimum amount of information for an imaginary main route and one or more secondary routes. In particular, the most simplistic table of the above-mentioned Japanese buildings cannot be between N and P. An imaginary route, and another imaginary route between p and s, and another imaginary route between s and T. This is of course unlikely, because in the free-driving mode, the user is likely to have no equipment. Navigation function 'because the user is known The most direct route between its starting point and its desired position, and more likely, in the case of a Japanese standard, the turn at the intersection indicates that the various segments can be replaced by a single imaginary calculation route between _τ, which is The route actually selected by the user is the same. Therefore, during the compression process, the device iterates through the turning point and tries to merge it. Using the above example, the process logic is as follows: the device will try to plan the path from the Ν to Ρ Check if 〇 is included in the path. If so, you will plan a new route from Q to Q and see if 〇 and 卩 are in the path of the planned route, and so on. If this is not the case, the item will be replaced by an item and compression will continue. This process will continue until all turning points are included in the campaign. Other algorithms such as individual and conquer may also be used in this compression. 127909.doc -27- 200930978 In the planned route mode, the following temple π »1 , ^ greatly reduces the information record as described below. In this case, the device Xu Zengu ^ calculates the route that the user at least partially follows. The following is the minimum set of events recorded in the Planned Pathway---Study-Bathroom mode: 'When a business (personal or personal) activity is specified, · When planning a new route, • When changing or deviating from the planned route When, • when arriving at the destination. 〇 For example, the user specifies that the purpose of the trip is for business or personal purposes, and then enters the target location. The device plans a new route from the current location to the target location. If A and D indicate the current and target positions, respectively. Along this route, near location B, the user changes the route for some reason and does not follow the suggested route. The device will make a new route plan from the current location, and the calculation of the deviation or new route may be an event that triggers the information record. Near the SC in the new route, the user again decides to change the route away from the established route. Soon, the device made a new plan for the target location. Similarly, after detecting a deviation from the calculated route or after calculating a new route, the information is recorded. Finally, reach the target destination D. The user sets the event to personal use. Using the events defined above, at the end of this journey, we will have the following journey log files: Activity set to business use: total ·· 5〇〇〇km [date/time J route from A to D planning (total: 5〇〇〇km)[曰期/time or incremental illusion change route near B (A_B ·· 5 km, total: 5〇〇5 yield) [Date / 127909.doc 200930978 Time or increment b] Recalculated from B to D (total: 5005 km) [曰期/time or increment e] Change route near C (BC: 1〇km, total: 5015 km) [date/time or increment d] from C to D recalculation (total: 5015 km) [time/time or increment e] - arrival destination D (CD: 25 km, total: 5040 km) [time/time or increment f] activity set to Personal use: Total: 4〇〇km [曰期/time or increment g] © It should be noted from the above that it is necessary to record the actual date and time, and only record the first date and time and subsequent changes. the amount. The above events are all recorded as actual space events. However, time and device events can also be used to enhance the invention. For example, it is possible to automatically enable the "Business" mode when leaving the field in the morning during work, and to 'discontinue""business" mode again when the afternoon arrives in place. Another interesting event is when the device position does not change over a long period of time. These records based on fixed time and location are still valid events, but may result in a larger log file © size.
