Description

  The present invention relates to a navigation device used for all types of mobile objects.

Conventional technology

  According to the prior art, when the travel area is a region, the information provided to the user by the navigation system satisfies the visual interest in addition to the current position and course displayed on the map, instructions at each intersection 3D images, illustrations, and so on, have been developed away from the functionality, safety, and responsiveness that the system must have. The navigation system has been actively developed as a national project in Japan, the United States, and Europe for over 20 years. The map-based Japanese map system, for example, allows drivers to read maps. It is prohibited or restricted in Europe and the United States as being unfavorable in terms of traffic safety. On the other hand, in the guidance method in which instructions on Western courses are given with arrows or voices, there is a high possibility that an erroneous instruction will cause an accident, and in order to reduce the accident occurrence rate due to such a mistake guide, the guidance is canceled on the main road. However, it is necessary to abandon the function originally required for the system to reach the target in a pinpoint manner. The current products are only used together without solving the drawbacks of these map and guidance methods, they are simply supplied to the market as an object of interest, and these products are used by the media as a safety issue. The danger of being done is often pointed out through media such as television and newspapers. However, the navigation system is originally a key technology for road traffic systems that mainly eliminates traffic jams and manages traffic, and fixed information devices and mobile devices are the central medium of multimedia as society becomes more computerized. This is a technology that one mobile information device as an information terminal roughly classified into information devices should have, and should be the basis of the entire system. Among the conventional technologies, the technology related to the hardware system has established a considerable accuracy and has sufficiently reached the practical level, but the software system is not at the practical level, and many problems remain in the navigation system.

  In particular, when the travel area is a local area and an urban area, elemental conditions such as functionality, safety, and responsiveness are essential for navigation to be used as a key system in road traffic systems and multimedia. Must be charged as. Functionality to reach the target when the target is set, safety that is guaranteed by excluding problems that are extremely dangerous in terms of traffic safety such as carelessness ahead and misguided, accidents, traffic jams, weather The navigation system can play its role if it is established that it is capable of smooth traffic by taking in enough dynamic information. These are the main problems solved by the present invention. When the travel area is a mountain area, sea area, or air area, a navigation system suitable for the type, purpose, and skill of the moving body is required.

  The field of solving the problems left by the prior art is in the software system, and improvement of the software is impossible unless the conventional technical idea is fundamentally changed. According to the conventional way of thinking, as long as it is a navigation system, a positioning function such as “Where are you now” and a guidance function “how to go” are natural, and equivalently, such a function is fixed as a navigation function. Have been considered. For example, the current position is informatized using various representation methods to be strictly matched with the background information as map information. Two-dimensional drawing is not enough, and it is drawn in three dimensions. It depends on a wide variety of expressions such as foreground expression with reality seen through glass and detailed map of 25 meter scale, and it becomes impractical and more dangerous just by providing psychological satisfaction and visual interest to the driver. It has been. Even though the guidance function should not take away the driver's vision, it is thought that it should be based on voice instructions only, which is increasingly stressing both the system and the driver.

  The reason why the development of Japan, the US and Europe is in turmoil is because it was bound by the conventional technical idea, and because the fundamental analysis of what a navigation system is and how it should be has not been made. This is because the information itself used in the system was not analyzed as a premise. It is psychological expectation as an old traveler that the user of the system tries to collate with the background information as one of the information of the current position and the travel area, and it is only confirmation in the travel. Especially for urban travel, what should be done is the final function that should be skipped when the system is incomplete and the infrastructure is not yet developed, and it is an ideal and ideally assumed function. However, it should be considered unrealistic considering data maintenance, positioning accuracy, driver traffic psychology, and complex and diverse traffic conditions.

  To solve the confusion of the navigation system, it provides useful information that tourists need in practice without being concerned with the location and guidance functions such as “where are you” and “how to go”. It is necessary to analyze, select, and process information related to travel as a basis. The present invention solves the problem by presenting such analyzed, selected, and processed information to travelers.

As a moving body can type for example people, motorcycles, passenger cars, large cars, aircraft, such as a ship. In accordance with these types, basic information for providing a system that guarantees the functionality, safety, and responsiveness described above must be presented. It is also conceivable that various kinds of conventional additional information are activated by providing such useful basic information. According to the present invention, the unit of the non-conforming band classified based on the type of the moving body and the suitability by responding to other travel-related elements is calculated as a cell, searched, output, and displayed. Shows the cell as the status of the travel area, and around the current position, around the target, the travel area including the current position and the target, a related cell or a common cell when the cells obtained for the current position and the target overlap, Various information such as the display, blank display that touches the cell as the cell attribute, the cell that overlaps the line connecting the current position and the target, the cell that touches the course, the trajectory, the traveling direction, the vector of the moving object, and the target direction Output and display cells related to.

  Living information, business information, leisure information, and general map information are added selectively and purposefully. Depending on the type and situation of the moving body, the scene, and the mode used, it is output and displayed on the display provided on the mobile phone, and is presented on the instrument panel, dedicated monitor, windshield, etc. in the car. When the mobile phone is set at a predetermined position, it is output and displayed on an instrument panel, a monitor, a windshield, etc., and an electronic notebook is also a target. The storage unit includes a card and a CD, and a transmission unit through communication. Positioning includes GPS, beacon, communication base, user input, and sensor. When used in aircraft and ships, vectors and cells are used as information.

Action

The travel area is divided into regions, sea areas, and airspaces, and a travelable band in each travel area is set as a blank, and a unit band that is not suitable for travel and is closed by a blank is output and displayed as a cell. When the travel area is an area, a cell is calculated, searched, output and displayed depending on the type of the moving body and the situation of the area. Based on the type of person, ordinary vehicle, large vehicle, etc., cells are calculated and searched according to the distance between the current position and the target, accidents, traffic jams, regulations, etc. A cell related to the current position, such as a local cell and a cell around the current position, a cell in the vicinity of the current position, a cell to which the current position belongs, a blank to close these cells, a cell adjacent to these blanks, and so on. As cells related to, cells around the target, cells near the target, cells to which the target belongs, blanks closing these cells, cells adjacent to these blanks, and the like are output and displayed.

When a cell related to the current position matches a cell related to the target, this is explicitly output and displayed as a common cell by voice and image. In addition, cells on the line segment that connects the current position and the target, cells that are adjacent to the blank that forms the course from the current position to the target, etc. are output and displayed, and these are related to the current position as one of the cells related to the target. A common cell with the cell to be searched is obtained and explicitly output and displayed. Using the above cells and blanks as basic information, dynamic information such as traffic jams, accidents, and weather is output and displayed as additional information. Since cells and blanks in the present invention are simple as basic information, it is possible to use blank spaces, and background information, landmarks, other business information, life information, tourism information, leisure information, etc. are presented as one piece of map information. . Compared to the case where the conventional map method is presented without selection, according to the present invention, the additional information is used selectively and selectively.

  Similarly, in the conventional guidance system, as compared with the case where stress is applied to the system and the user, the present invention provides various types of information in a manner without such a load. When the travel area is a sea area, cells and blanks are output and displayed, and a vector indicating the speed and direction of the moving object and an ideal vector that can avoid the cell are output and displayed. It can be used to determine direction and speed to match. When the travel area is an airspace, the vector of the cell, the moving body, and the ideal vector are calculated and output in a three-dimensional manner using airflow as an element.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, 1 is an input unit, 2 is a central processing unit, 3 is an output unit, and 4 is a locator for locating the position of a moving object. The navigation apparatus according to the present embodiment is generally used for people, automobiles, aircraft, ships and the like. The input unit 1 gives various commands or data, and is input by keys, a touch panel, voice or the like. The central processing unit 2 is configured by a computer and includes a processing unit 5, an arithmetic and retrieval unit 6, and a storage unit 7 therein. The storage unit 7 stores a calculation program for executing this embodiment, a program for search processing, and necessary data. It is also possible to use wired or wireless communication means for input, and it is possible to store transmitted programs and data.

  The processing means 5 has a processing function realized by a program and data stored in the storage unit 7. The arithmetic / retrieval means 6 has a function of searching the data in the storage unit 7 and obtaining necessary data based on the command of the processing means 5. The output unit 3 outputs and displays information by sound and image. It is composed of a CRT, a liquid crystal display, a HUD displayed on a glass, a speaker, etc., and is provided in a cart, a car, a mobile phone, an electronic notebook, an aircraft, a panel near the operation seat of a ship, and the like. The locator 4 has a function of locating the current position of the moving body. Locator 4 includes various sensors that measure distance and azimuth, satellite radio positioning devices, beacons that are installed on the roadside to send information about positions, positioning devices that measure positions by communicating communication bases, users can hear information about positions, There is a method of inputting with a key or a touch panel and locating the position based on the input information.

  Next, the operation executed by the above configuration will be described with reference to FIG. The operation by the navigation device is executed by various processing means realized by the processing means 5 and the calculation / search means 6. First, a target is set by the input unit 1 and input to the central processing unit 2 (step 11). The method of inputting the target is arbitrary. Target information such as target name, phone number, address lot number, code name, code number, symbol, various identification methods, latitude / longitude, postal code, nearby landmarks, etc. are keys, touch panel, cursor, voice, barcode Input by a reader or any other device and means. Next, the current position is input to the central processing unit 2 by the input unit 1 and the locator 4 (step 12).

  Information on the current position is input in the same manner as the user inputs information on the target. Examples of information relating to the current position include nearby landmarks, facilities, address lot numbers, code names, code numbers, symbols, location maps, roads, intersection names, etc., and are arbitrary. As locators, those based on positioning radio waves transmitted from satellites, those based on distance sensor, direction sensor, acceleration sensor detection, beacons installed on the roadside, radio waves from transmitters, sound waves, lasers, etc. It is optional, such as by positioning with a communication base station, by a bar code attached to the road surface, or by a magnetic signal. Information about the target and the current position input by the processing means 5 in the central processing unit 2 is held.

  Next, the processing means 5 obtains respective position data based on the target and current position data. Then, the calculation / retrieval means 6 is operated to calculate a blank, a cell, and a common cell, which is adjacent to the data based on various data stored in the storage unit 7 and data on the target and the current position, from the stored data of the storage unit 7. This is obtained by searching (step 13). In step 14, the data relating to the cell obtained by the calculation and search means 6 is held in the processing means 5, and further sent from the processing means 5 to the output unit 3. At this time, various additional information is also sent from the processing means 5 to the output unit 3. The processing means 5 has a sound and image output display function for outputting and displaying required sounds and figures in the output unit 3. Therefore, the data and information sent to the output unit 3 are converted into a form that can be output and displayed by sound and image.

  As described above, the cells and the various additional information sent to the output unit 3 are output and displayed in step 14. 3 to 9 show display examples of the screen of the output unit 3. FIGS. 3 to 9 show display examples displayed by the output unit 3 as both images out of the sound and the image output and displayed from the output unit 3, respectively. In FIG. 3, 21 is the target to be reached, 22, 23, and 24 are cells, and the cell 23 to which the target belongs and the cell adjacent to the target's latest blank have the same relationship as the cell to which the target belongs. Cells 22 and 24 in the same sideband are displayed. In FIG. 4, 25 is the current position, and 26, 27, and 28 are displayed as cells adjacent to the left side of the blank when the travel is limited to the left side among the cells connected to the blank where the current position is located. Has been. FIG. 5 shows a cell that touches the left side of the blank when it is limited to left-hand traffic, for example, among the cells that touch the blank constituting the course from the current position to the target.

  FIG. 6 shows an example in which cells 29, 30 and 31 bordering on the left side of the blank constituting the course are displayed, and when the current position travels away from the course, the blank where the current position is located. An example in which 32 is explicitly displayed as a common cell when a cell that is adjacent to the left side of the blank and a cell that is adjacent to the course coincide with each other among the cells that are adjacent to each other. FIG. 7 explicitly shows these common cells 33, 34, 35, 36, and 37 when a cell related to the target and a cell related to the current position generate two or more common cells. In FIG. 8, the cell related to the target and the cell related to the current position generate a common cell, and when the cell is one, the common cell 38 is explicitly displayed. In FIG. 9, the vector of the moving object is displayed as 39, and the ideal vector that avoids the cell 41 is displayed as 40.

  In general, moving objects are classified into people, hand carts, bicycles, motorcycles, ordinary cars, large automobiles, etc. when the travel area is a region, and small ships, large ships, Cases can be classified into helicopters, small airplanes, and large airplanes. Depending on the type of the moving body and the situation of the travel area, the travel mode varies, and dynamic information on traffic congestion, accidents, construction, weather, sea area, air current in the air area, ocean current, weather, etc. is an important factor. A navigation system corresponding to the type should be constructed as follows.

  With respect to a person as a mobile body traveling in a region, a cell is as follows, with a unit band not suitable for travel as a cell. Areas can be classified into urban areas and mountain areas, and the unit of bandwidth that is not suitable for human travel is determined in light of physical and artificial travel factors. It is also possible to evaluate the suitability from the viewpoint of economy and efficiency. The cell is a unit band that is not suitable for a person's travel and is independent of other cells. The cell is blank between cells, and the blank is suitable for travel. It is a unit band because it is independent in the area closed by the blank. In general, cells are not suitable for travel in light of physical and human factors. It is possible to classify physical cells that are dangerous and difficult for people to walk and artificial cells that are not suitable for travel due to regulations, ownership, and management. Blanks that close physical cells are suitable for human walks. In urban areas, roads, plazas, and passages within the facility are accessible, and walks are impossible or difficult in the mountains. Except for cells that are or are restricted for some reason, it is a margin that excludes cells because it is suitable for people to walk or travel.

  Since the evaluation of suitability depends on the individuality of the person, there are cases where it is required to calculate and search for cells and blanks according to the purpose, physical strength, skill, occupation, etc. Save the element as data and present cells and blanks. In addition to a blank that closes a cell, a blank that does not close the cell, for example, a band such as a road or a plaza that is suitable for travel in the cell, can be treated as additional information. In facilities such as theme parks, subway premises, department stores, hospitals, museums, factories, warehouses, etc., calculation, search, output, and display are divided into cells and blanks. There are hand carts and bicycles as one of the types of mobile objects, but it is also possible to make another evaluation of cells and blanks depending on whether they have suitability in light of the functions of these devices.

  Motorcycles and automobiles have a variety of physical and man-made conditions as criteria for separating cells and blanks, and differ depending on elemental conditions such as the function, personality, purpose of travel, laws and regulations, and management. The size of the vehicle physically determines the possibility of travel, and the evaluation of suitability varies depending on traffic regulations, especially in urban areas. Since it varies depending on the purpose and business, it is practically determined that the general system is physically travelable, and the type of moving body is a motorcycle, small car, ordinary car, large car, special car, Regulations such as legal restrictions and regulations for management, etc. can be presented together with basic information such as cells and blanks as additional information. As an example, the travel possibility is evaluated according to the above-mentioned various types, and the cell is calculated and searched. When roads and bands belonging to a region are evaluated according to the type of mobile object, the size of the mobile object is divided into ranks, especially in urban areas, and roads and bands are ranked according to this rank. Therefore, the cells can be classified into ranks depending on which rank roads and bands are in the cells. Alternatively, the cell rank can be set in accordance with the distance from the current position to the target.

  At this time, the road and the band are evaluated according to the distance, and the suitability of the cell is determined. Divide the cells that overlap the line segment connecting the current position and the target by an arbitrary number and treat the number of cells together as one cell, or the cells that are adjacent to the course from the current position to the target in the same way It is also possible to treat the number of cells obtained by dividing by an arbitrary number as one cell. It is desirable to divide by what number is proportional to the distance from the current position to the target. Depending on the type of mobile body and various situations, the purpose of the trip, and the user's taste, as a general example, the cell classified by the evaluation of the road band to which it belongs is associated with the distance from the current position to the target Thus, it is desirable to make the length of the distance proportional to the size of the cell. For the cell where the target is located, it is desirable to calculate and search for a smaller cell at least in the final scene of the trip, for example, at the stage of approaching the target.

  It is possible to associate the cell with the current position and the distance to the target, or as a result. As the distance from the current position to the target becomes shorter, the required cell becomes smaller, so the same result is obtained. It is also possible to calculate and search a road where a restriction for traffic management such as direction restriction, weight restriction, vehicle type restriction, etc. is attached, and an area where a band is located as a cell. These regulations are treated comprehensively and selectively. It may be evaluated as a cell when it lacks suitability for security, order and safety. Since statistical aptitude is often lacking, it is possible to evaluate, calculate, and search as a cell.

  In this way, typically, the possibility of travel and suitability for travel may be evaluated according to the type of mobile body, the distance from the current position to the target, various regulations, properties, and the like. Or the suitability is evaluated in the light of the travel elements set arbitrarily, storing the suitability as an attribute for travel elements such as the type of mobile object, purpose of travel, user skill, economy, etc. Present cells that have been evaluated as suitable for all of the configured travel elements. At this time, the blank that closes the presented cell can be selected based on the judgment that the outer periphery of the presented cell has a travel possibility as a band suitable for travel.

  As a general example, the type of mobile object, particularly a cell whose suitability is determined by the size, is converted into data and stored in the storage unit 7, and when a mobile object type is input, a search is performed corresponding to the type. The cell is output as sound or image and displayed. Similarly, cells determined by various regulations are converted into data and stored in a storage device, and cells are determined and converted into data according to other elements, and these cells are searched, output by voice, image, etc. and displayed. It is possible to calculate and search for cells related to travel based on blank net data and execute the program to expand the area until it is blocked by blank, and specify the expanded area with coloring, sign, line, etc. Is possible.

  In each embodiment, it is optional to specify a cell that is calculated and searched in a special expression, or to specify a region other than a cell with a blank space. It is also possible to use a cell area as a margin for presenting additional information. Based on this information, the cell is selected based on this information, such as the trajectory, current position, traveling direction, target direction, target, course, line segment connecting the current position and the target, blank where the current position and the target are respectively located, and the region to be traveled. When calculating and searching, display blanks such as roads and bands on the screen, expand any area of the cell until it is blocked by blanks, clearly indicate the area obtained by expansion, and be located in the travel area It is also possible to display both blanks and cells.

  Blanks are large and small, whether they are regulated, fees, and other characteristics, conditions, individualities, and elements that can be classified as blanks, and rank them, and expand the area until they are blocked by the appropriate classification or rank. It is also possible to display the obtained cells and blanks. Blanks are large, small, whether or not they are regulated, charges, and other properties that can be classified as blanks, categorized by condition, individuality, element, expanded until the rank prevents them, and the resulting cells and blanks are displayed together It is also possible to do. A cell is expressed by a color, a line, a symbol, etc., and a blank inside the cell and an external blank are simply blanks, or are expressed by a color, line, symbol, etc. different from the cell. The blank where the current position is located can be set as an arbitrary area, and the area can be expanded until it is blocked by the same type and rank blank as the blank where the current position is located, and the obtained area can be expressed as a cell. .

  Alternatively, classifications and ranks are structured hierarchically, and if the difficulty level for travel is as an element of categorization and ranking, the degree of difficulty will be high. The rank blank may be treated as not preventing the expansion of the area. it can. When information related to the target is input by the input unit and the cell to which the target belongs is calculated and searched, the cell is related when the cell is determined by the type of mobile object, the purpose of travel, the situation, the nature of the region, and other factors It is also possible to output and display a blank and a cell adjacent to the blank, and to perform an operation search for a cell related to the current position based on the same classification and rank as the cell at this time.

  The cell can be expanded until it is blocked by a blank of the same classification and rank as the current location, and the target is in the blank or inside the cell and close to the blank At this time, it is desirable to obtain cells by expanding until they are blocked by the same classification and rank blanks as these blanks. It is possible to output and display a blank that is close to the target or where the target is located, and output and display a cell determined based on a blank of a different category or rank. It is also possible to display both a cell determined based on a blank that is close to the target or where the target is located and a cell that is determined based on the blank where the current position is located. In general, each element related to travel is input and a cell is calculated. However, the cell can already be stored in the storage unit 7 as data as follows.

  A cell is determined for each type of mobile object corresponding to the type of mobile object, and the cell is searched according to an arbitrary selection. When a motorcycle is selected and set as the type of mobile body, a cell that is incompatible with the motorcycle is searched, and when it is a large vehicle, a cell that is incompatible with the large vehicle is searched for and displayed. Cells are hierarchically converted into data from humans and motorcycles to large vehicles and output according to the selection. When cells belonging to one hierarchy are output and displayed, cells in other hierarchies can be displayed. In that case, it is desirable to differentiate the cells in the main hierarchy from the cells in the subordinate hierarchy. . It is possible to specify the main cell, or to display only the blank that closes the cell.

  It is also possible to simplify the correspondence between the type of mobile unit and the cells to be hierarchized. When a mobile unit type is set by roughly comparing the mobile unit and cell hierarchy, it is standard for that type. It is also possible to search for the selected cell by searching for a cell corresponding to the above, outputting and displaying it, or arbitrarily selecting a hierarchy of cells considered appropriate by the user. The unit band of the cell may be specified, or a blank for closing the cell may be specified. When it is meaningful to classify as a different type of property such as an expressway, general road, toll road, exclusive road, etc., treat it as a blank for each class, and expand the area until it is blocked by this blank to obtain the cell area In addition, when the current position is located in each type of blank, it is desirable to extend the area until the current position is blocked by the same type of blank as the present blank.

  When the travel area is Yamano, the cell is calculated and searched according to the function and personality of the moving object. Cells are determined in light of the functions and personality of moving objects such as wetlands, bad roads, grasslands, and ramps. Furthermore, as a typical example, priority is given to travel elements, the cells are calculated and searched by the essential elements, output and displayed, and the elements are gradually input to set the classification rank of the cells presented by the user's arbitrary judgment . In general, the type of mobile unit is given priority, the distance between the current position and the target, the cell that overlaps the line connecting the current position and the target, and the cell that touches the blank that forms the course from the current position to the target It is also possible to change the cell to each rank cell with reference to the form and distribution. If the continuity of the cell is not interrupted by railways, rivers, etc., present both the cell that overlaps the line segment that connects the current position and the target and the cell that borders the blank that forms the course. It is also possible to change the rank until the cells in both groups have continuity in order to give an alternative to overlapping cells and cells involved in the course.

  Since the goal usually belongs to a cell, when creating the goal data, the lowest cell is given as part of the goal data as the goal attribute data, and the goal location is entered when information about the goal is entered It is also possible to search for the lowest cell to which the target belongs, and to perform an operation search for cells of higher ranks as necessary in each embodiment. In the case of a target that is set at any time, the cell is obtained by expanding the area until it is blocked by the blank centered on the target, or when the cell is created and stored as a data, the cell to which the target belongs is searched. Thus, the lowest cell can be obtained. Alternatively, the uppermost cell in the travel area where the target is located is searched for operation, and the lower rank cell where the target is located is calculated and searched. In this case, the lower cells are included in the upper cells.

  For the current position, expand the area around the current position until it is blocked by a blank to obtain a cell, or if the cell is stored as data, search for the cell where the current position is located, or the current position is blank When the current position is located in the area, the smallest cell in which the blank where the current position is located is circulated is searched for the smallest cell. As an example, when a cell as a section is placed in a pseudo manner and information about the target and information about the current position are input, the section cell closest to the target and current position is searched from the section cell using a method such as nearest point search. It is also possible to compute and search for cells to which this segmented cell belongs.

  As a simple example, cells corresponding only to the type of moving object are stored as data, and it is possible to select and combine unit bands that do not match humans, motorcycles, ordinary vehicles, and large vehicles according to the user's operation and program. It can also be done. Except for the specification to change the upper cell and lower cell to each other, when simplifying and placing importance on the environment of the current position, the cells around the current position, the cell to which the current position belongs, the current Outputs business information, living information, leisure information, etc. as target direction, traveling direction, trajectory, landmark, intersection, various information, as well as cells near the position, cells that close the cells related to these current positions indicate. Furthermore, dynamic information such as traffic jams, accidents, construction, and weather can be output and displayed.

  Furthermore, as a typical example, a travel area is a mountain area, a park, a zoo, a theme park, and the like. In general, including a sea area and an air area, a cell that overlaps a line segment connecting a current position and a target is calculated and output and displayed. If necessary, information on the surroundings of the current position may be presented to assist the travel, or information on the target may be presented to assist in the selection of the target. It is also possible to input information related to the current position, target, landmark, etc. by reading the number and code written on the paper surface and using the panfrette, magazine, etc. In order to add interest, voices and images may be effectively produced and a message may be provided using characters. It is desirable to output and display effective audio and images at each stage in the course of arrival. When a cell is stored as data, it is possible to use it for the convenience of calculation search by giving a cell in the vicinity of the cell, a blank adjacent to it, a cell in the same sideband, a higher and lower cell, etc. as data. is there.

  When the travel area is a sea area, the evaluation of elemental conditions such as the depth of the seabed, sea current, wind, etc. differs depending on the size and classification of the ship, and the cell as a unit band having no suitability varies. In general, basic cells are calculated and searched based on the depth of the seabed, the strait, and the shape of the bay as static conditions, and conditions such as the direction of the ocean current, velocity, wind direction, and wind speed are added as dynamic conditions. The course from the current position to the target should be considered economically, and the course and speed are calculated according to the static and dynamic conditions, the size and classification of the ship. In the case of automatic navigation, these calculations and operations are performed automatically, but in the case of manual navigation, it is obtained from the cell determined by static conditions, the current and wind, the vector given to the hull, and the power and steering vector of the ship. It is desirable that an ideal vector calculated so as to avoid the cell from the vector of the moving object, the static condition, and the dynamic condition is calculated and output and displayed.

  When the travel area is airspace, the suitability of the airspace is determined by the model. The course differs from sailing, takeoff, and landing. In any case, there is generally a planned route, but it is required to cope with variations in weather, airflow, etc., and when these dynamic conditions are added, three-dimensional Therefore, the cell is calculated. At this time, cells, aircraft vectors, and ideal vectors that are not suitable for travel are calculated, output, and displayed. Speed setting and steering may be automatically performed so that the ideal vector and the aircraft vector coincide. Speed is set and steered.

  Examples according to the present invention will be described below. Each example is divided into Examples 1 to 26 for convenience of explanation. In the description of each embodiment, the central processing unit 2 will be described assuming circuit elements having a predetermined processing function. Each embodiment is arbitrarily selected and combined in the application and scene as necessary.

[Example 1]
In this embodiment, when information relating to a trip is input by the input unit 1, data relating to the travel area is retrieved from the storage unit 7, and a cell is computed and retrieved by the computation retrieval means 6 via the processing unit 5 and output to the output unit 3. Is displayed. Various aspects are possible as to how information relating to travel is provided to the input unit 1 and what is provided to the input unit 1. Information related to travel by input from voice input devices, keys, touch panels, bar readers, wireless and wired receivers, dynamic information such as current location, target, type of moving body, weather, traffic jams, accidents, etc. Basis for assessing the travelability and suitability of travel areas as travel targets, including information on regulatory elements such as additional information and regulations, management, economics, user skills, cost, regulatory factors such as economic factors, and human factors , And a unit band that is not suitable for travel is calculated as a cell, retrieved, and output and displayed as an audio image in the output unit 3.

  The travel area to be traveled is when the current position is obtained by user input, positioning by satellite or communication radio waves, reception of position information by sound waves, lasers, beacons, etc., and other various sensors for locating the current position In addition, it is determined by setting a range developed in the traveling direction, or determined as a range of data relating to the travel area. When the travel area is determined as the range developed in the traveling direction of the current position, the size of the range is determined by the user's arbitrary setting, or the range that can be moved per unit time according to the function of the moving body Become.

  Or, in travel information, for example, a travel area determined by arbitrarily scanning and selecting a travel area by prioritizing economic factors, prioritizing mobile functions, or prioritizing weather conditions. It is also possible to calculate and search cells and display them. Alternatively, an appropriate travel area can be selected while checking the cell distribution and shape, and the cells in the travel area can be output and displayed. There is also the use of selecting a travel area by checking the occupancy of cells within a certain range. Select some of the travel elements that are the basis for calculating and searching for cells in the information related to travel, and search for cells based on these travel elements. It is also possible to select.

[Example 2]
When a travel area to be traveled is planned, when all or a part of the range of the travel area planned or considered is input by the input unit 1, Data relating to the range is retrieved from the storage unit 7, the cell is computed and retrieved by the computation retrieval unit 6 via the processing unit 5, and is output and displayed on the output unit 3 by voice and image. Various aspects of how information is provided to the input unit 1 and what provides such information to the input unit 1 are described below.

If an arbitrary range is given by name, symbol, code number, code name, landmark, or any other information that specifies the range by input from a voice input device, key, touch panel, etc., it is not suitable for travel located in that range The unit band is calculated as a cell, retrieved, and output and displayed from the output unit 3 by voice and image. Cells are also output and displayed when the travel area is air and sea. The range of the travel area can also be changed by changing the scale by voice, key operation, or the like. According to the present invention, essential information for travel is extracted, and additional information such as characters and illustrations can be omitted as secondary information . For example , even a small screen provided in a mobile phone, an electronic notebook, etc. It can be used fully, navigate with a mobile phone when walking, and when you get on a motorcycle or car, set the mobile phone etc. in a predetermined position and connect it to the in-vehicle device, display it on the windshield, Applications such as displaying on a shared panel become possible. There are examples in which an electronic notebook, a portable personal computer, or the like, which is a portable terminal, also has a communication function, a locator, and the like, and can be applied as described above.

  As locators, there are positioning by satellite radio waves, positioning by communication bases, input of information by users, etc. When in the area, location information and area information are issued to roadside facilities, buildings, telephone boxes, vending machines, etc. A transmitter can also be installed. The apparatus of the present invention may be attached to a hand cart and used in facilities such as department stores, museums, hospitals, and theme parks. Data relating to the travel area is stored in the storage device 7, but data of a specific travel area can be transmitted by communication, provided by a device installed in the travel area, or rewritten. Specific media such as a CD, an IC card, a chip, and a flash memory are arbitrary. In conventional examples, characters and illustrations have been frequently used. However, in the present invention, such additional information can be output and displayed for purpose and selection, so that the functionality can be emphasized.

  Since tourist information, shopping information, living information, business information, and the like are selected, the information is more useful than information presented in a random manner. In a region, for example, it is desirable to present landmarks at intersections, intersection names, etc., as well as when approaching or designating the intersection.

Example 3
When the target name, code name, code number, symbol, telephone number, position, etc. are given from the input unit 1, cells around the target are calculated, searched, output and displayed. A travel area within an arbitrary radius centered on the target is output and displayed according to the user's arbitrary setting or automatic setting, and a cell is presented. At this time, it is desirable that cells of appropriate classification and rank are output and displayed automatically according to the scale of the travel area or when the cells are classified or ranked by arbitrary selection. It is also possible to shift the cell rank from a small cell to a large cell in proportion to the increasing radius.

Example 4
When the target is inside the cell and belongs to the cell, the cell is displayed and the target position is indicated inside the cell by sign, symbol or the like. If the target position touches a blank that is bounded by the cell to which the target belongs, this blank is classified as a recent blank in the target, and if there is no recent blank and the target position is inside the cell, or when the mobile reaches the cell or when the traveler changes the type of the moving object, and calculating whether there is an internal enable travel band cell mobile new types as elements, If there is a travelable band, this cell may be used as a blank, and when a cell closed by this blank is formed, this cell may be output and displayed. When no cell is formed, a blank is output and displayed in the cell to which the target belongs.

Example 5
When the target is not in the cell and is located in a blank that is a travelable band, the target position is indicated in the blank, a cell near the target is calculated and searched, and output and displayed on the output unit. It is arbitrary whether only one of the neighboring cells is output and displayed, or two or more cells are output or cells within a certain radius from the target are output and displayed. An example where the target is blank is not a case where there is any facility as a target. The travel area is determined by whether a predetermined position is a target or a secondary point is set as an elapsed point. Especially useful when you are in sea or air.

Example 6
Information that defines the current position of the mobile object, such as latitude or longitude, relative position in coordinates, landmark facilities, place names, point names, road names, intersection names, relative positions with communication stations, and other current positions Is calculated, searched, output, and displayed in the travel area cell where the current position is located. It is also possible to make the travel area and cell rank proportional. Alternatively, the travel area where both the target and the current position are located is automatically set by the user's selection and setting. When the travel area not including the target is output and displayed, the target direction is presented. Alternatively, a part of cells adjacent to the blank constituting the course described below is output and displayed, or a part of cells overlapping the line segment connecting the current position and the target is output and displayed.

Example 7
When the current position belongs to the inside of the cell, a cell with a classification or rank that is not originally adapted is calculated and searched and output or displayed, or a blank which is a travelable band is calculated and searched and output and displayed. Alternatively, all the category rank blanks within the cell to which the current position belongs are searched for operation and displayed. In this case, it is also possible to output and display whether it is physically incompatible or whether it is due to regulation or management.

Example 8
If the current position does not belong to a cell and is blank, a cell near the current position is searched for operation and displayed. Search for a cell within a certain radius adjacent to the blank where the current position is located, or select a cell that extends to the blank according to the blank's extensibility if it is the latest one or if the blank has extensibility. Search for calculation and display output. If the travel area is a sea area and an air area, at least two cells are output and displayed to express the blank spreadability where the current position is located, and if three or more cells are output and displayed, the blank spreadability and shape Is expressed.

  In this example, it is desirable that the cell search is performed along the traveling direction of the moving body. When the travel area is an area, two or more cells are output and displayed in the mountain area to express the blank's spreadability and shape, and in the urban area there is a possibility of travel and the blank shape and density that can be substituted Expressed. At this time, it is also possible to perform an operation search for a cell that is closed by the same classification and rank blank as the blank where the current position is located. When both the current position and target are output, the blank is located, or when the target belongs to a cell, it is closed by the blank of the same category and rank based on the latest blank of the target. It is also possible to compute and search for cells and display them.

  Or when a cell that overlaps the line segment connecting the current position and the target, or a cell that touches the blank that forms the course from the current position to the target is being searched for, or when these cells are output and displayed A cell having the same classification and rank as these cells is calculated and searched as a cell in the vicinity of the current position. Alternatively, the user can arbitrarily select the cell classification and rank by taking into account factors such as the type of mobile unit, purpose of travel, economy, required time, traffic jam, accident, etc. It is also possible to do.

Example 9
In the example in which both the cells around the target and the cells to which the target belongs are output and displayed, or the cells in the vicinity of the target are output and displayed, the cells to which the target belongs and the cells in the vicinity of the target are explicitly output and displayed.

Example 10
In the example where both the cells around the current position and the cell to which the current position belongs are output and displayed, or the cells in the vicinity of the current position are output and displayed together, the cell to which the current position belongs and the cell near the current position are explicitly displayed. Display output.

Example 11
A band having a suitability for traveling by a mobile object is set as a blank, and an operation search is performed together with a cell closed by the blank, and the output is displayed. Various factors such as the type of mobile body, user skill, purpose, economy, efficiency, difficulty, contractual conditions, legal compliance, travel mode, weather, airflow, wind, and other unforeseen circumstances Is involved. When information about these travel elements is obtained, the degree, possibility, difficulty, necessity, etc. are evaluated in light of this, and the possibility of travel is verified.

  The possibility of travel is modeled, and the band to be traveled is classified into cells and blanks, and the cells and blanks are evaluated by classification and rank according to nature, meaning, physical shape, effect, etc. A travel element may be extracted by giving information on area data and travel, and cell and blank may be searched. The cell is closed by a blank and formed as a unit area. When a cell is searched and output and displayed, and a blank that closes this cell is output and displayed, voice and image are used, but when displaying by image, line type and color selection to obtain visibility of the cell and blank is Is optional.

Example 12
When a cell and a blank that closes the cell are output and displayed, a cell adjacent to the blank that closes the cell is calculated and output and displayed. When cells that are adjacent to a blank are output and displayed, the cell is closed by the same classification and rank blank as that of this blank, and is output and displayed. When the current position belongs to a cell, all cells adjacent to the blank that closes the cell are searched for, and when the current position is blank, all blanks adjacent to this blank are searched for output and displayed.

Example 13
When a blank that closes a cell is expanded and extended to have spreadability, it is set as a spreadability blank, and the cell is output and displayed, and the spreadability blank is calculated and searched and output and displayed. If the nature, meaning, suitability, effect, and shape of a cell are internal attributes of the cell, the external attribute of the cell corresponds to the nature, meaning, shape, etc. of the blank that closes the cell. The spreadability of the blank is particularly important for the blank, and the spreadability of the blank that closes the cell is important for travel as an external attribute of the cell. When the current position belongs to the cell when the cell is output and displayed, and the blank that closes the cell and the stretchable blank are output and displayed, the same classification as the blank that closes the cell, and the rank blank is in the cell to which the current position belongs May calculate and search for this and display it.

Example 14
When a blank that closes a cell is a spreadable blank, a cell adjacent to the blank is calculated and output and displayed. The cells adjacent to the spreadable blank may be the same category or rank cell as the cell closed by the spreadable blank, and may be a different category or rank cell. You may make it a high-order large cell in proportion to the distance of a present position and a target. Alternatively, the cells may be classified into cells corresponding to the type of the moving object, and may be cells that are calculated and searched in light of travel factors such as economy, purpose, and skill. Or it is also possible to make the cell of the same classification and rank as the cell overlapping the line segment connecting the current position and the target, or the cell adjacent to the blank constituting the course from the current position to the target. When the blank that closes the cell is a spreadable blank, the cells adjacent to all the spreadable blanks can be searched for operation, displayed, and provided to the user for route selection.

Example 15
When the target belongs to a cell, the cell that is adjacent to the blank that is closest to the target, the cell that is adjacent to the blank when the target is located in the blank, and even when these blanks are malleable blanks. In the same way, search and output the calculation. When the target is located in the blank, a cell adjacent to the spreadable blank is output and displayed, and a cell to be avoided is presented. A blank that can be traveled when the target belongs to a cell, and a cell that is adjacent to the recent spreadable blank is output and the target is traveled from any direction to reach the target. A cell is presented as information for selecting an advantageous blank in light of. Specifically, when the travel area is a sea area and an air area, the target is located in the blank, and when the travel area is an area, it generally belongs to a cell.

Example 16
When the current position belongs to a cell, the cell adjacent to the latest blank at the current position, or the cell adjacent to the blank when the current position is located in the blank, these blanks are malleable blanks At the same time, the same operation search is performed and output is displayed. When the current position belongs to a cell and the latest blank at the current position is a spreadable blank, cells adjacent to the blank are output and displayed, and the distribution of cells to be avoided is presented as information. Such information is given by making a cell whose current position belongs to a cell and is adjacent to a blank that closes this cell to a cell of the same classification and rank as the cell to which the current position belongs. The current position is located in a blank, this blank is a stretchable blank, and the cells adjacent to this stretchable blank are output and displayed with the same category and rank blank as the blank where the current position is located. It will be possible to be given an opportunity to choose.

Example 17
When the current position is located in a blank that includes a stretchable blank, out of the cells adjacent to this blank, if the blank travel is limited to the left side, the cell that is adjacent to the left side of the blank is calculated and output. indicate. When it is limited to the right side, the cell adjacent to the right side of the blank is similarly searched and output and displayed. This is mainly done when the travel area is a region, and the cells are output and displayed in this manner, so that information that supports the selection of a route without being obstructed by direction restrictions such as prohibition of right turn or prohibition of left turn is presented. It becomes possible.

Example 18
When a target belongs to a cell and a recent blank is obtained for the target, among cells adjacent to this blank, a cell in the same sideband as the cell to which the target belongs is calculated and displayed for this blank. . The same applies when the blank is a spreadable blank. Which side band of the blank the cell to which the target belongs is located when the travel area is a region is useful information particularly when the mobile body is an automobile. In order to reach the target as close as possible when reaching the target, it is often obstructed by direction restrictions or restrictions that restrict traffic to the right or left. The route selection is supported by outputting and displaying a cell in the same sideband as the cell to which the target belongs.

Example 19
When information on the target and information on the current position are input, a line segment connecting the target and the current position is obtained, and a cell overlapping the line segment is calculated and output and displayed. When the travel area is a sea area and an air area, the distribution of cells existing between the current position and the target is presented. In the sea area and the air area, the moving body can travel in the same direction if it is indicated whether or not the cell is in the course. When the travel area is a region, various types of travel elements are involved in which classification and rank cells should be presented, and it is necessary to set the travel elements for calculating and searching the classification and rank. . Pattern some settings, or set the travel elements according to the menu when the user travels, or the basic travel elements are set, and this setting is used as the basis for the specific travel situation. The element is added or changed, and the cell is searched for calculation.

  For example, the type of the moving body is classified as a person, a motorcycle, a normal vehicle, or a large vehicle, and is set as a travel element. Whether it is an emergency car or a general car whose direction is to be lifted, depending on the skill of the user, whether it is elementary, intermediate or advanced, the function of the moving body when the travel area is Yamano, these travel elements In addition, elements related to conditions such as traffic jams, accidents, and construction are added. The classification rank of the cell is determined by these elements, and the cell is searched for calculation. However, in this example, even if a cell that overlaps a line segment connecting the current position and the target is calculated and searched, the continuity between the cells may be interrupted. Since a cell is calculated and searched as a unit band that is closed by a blank, for example, when a railway or river is in a travel area, even if the cell is presented based on the travel element selected as described above, In the categorical rank, the continuity of cells may be interrupted by railways, rivers, etc. At that time, it is processed by the program so as to search for cells of higher ranks and ranks that will already contain cells that have been presented, cells of ranks and ranks that are not interrupted by railways and rivers Is searched and output. Alternatively, a road that passes through the railway and river, such as a railroad crossing, a bridge, an elevated road, and a tunnel, is blanked, and a cell that is closed by this blank is searched separately. It is also possible to ensure the sex.

Example 20
When information on the target and information on the current position are input, a course from the current position to the target is obtained, and a cell adjacent to the blank constituting the course is calculated and output and displayed. In this embodiment, cell continuity is not a problem, and selection of a cell classification rank is important. For each of the cell related to the current position, the cell related to the course, and the cell related to the goal, for example, if the cell related to the current position is a cell of a lower classification or rank, the current position is in the blank constituting the course. Presents a lower cell until moving, and if the cell related to the current position is an upper cell, closes this cell.If the current position is located in a blank, presents this upper cell, and the current position is this upper cell. If there is a lower cell included in this upper cell, the lower cell is searched for operation and output and displayed. In general, lower cells belong to higher cells.

  Except for cases where railroad crossings, bridges, elevated roads, and tunnels are blanks and this blank closes the lower cells to form a unit area, the lower cells can be treated as belonging to the upper cells. Thus, a special example is stored as data and processed as attribute data of an upper cell or an adjacent cell. As for the cells related to the progress, dynamic conditions such as the distance from the current position to the target, the classification of the cells closed by the blank constituting the progress, the rank, the traffic jam, the accident, and the construction are added as travel elements. The cells of higher classification and rank are presented in proportion to the distance from the current position to the target. Based on the cells closed by blanks constituting the course, it is possible for the user to arbitrarily select and set the upper and lower cells of this cell. When dynamic information such as traffic jams, accidents, constructions, etc. is obtained and blanks constituting the course have lost suitability for travel, it is generally necessary to present lower cells. The cell related to the target may be processed so as to search for a lower cell in proportion to a decrease in the distance between the current position and the target. If there is a blank in the cell that does not close the cell when the target belongs to the cell, and this blank is useful to reach the target, present this blank.

Example 21
When presenting a cell that borders the blank that makes up the course from the current position to the target, if the trip is limited to the right or left side of this blank, for example, if the trip is limited to the right side, blank The cells that are bordered on the right side are output and displayed when they are limited to the left side. There are many areas where there are restrictions on turning to the left when restricted to the right side, and prohibiting right turns when restricted to the left side.

[Example 22]
The cells around the current position, the cells to which the target belongs, the cells in the vicinity of the target, the cells that are adjacent to the blank that closes these cells, etc. Specify cells that are close to the current position, cells that are adjacent to the blank that closes these cells, etc. as cells related to the current position, and when the cell related to the target matches the cell related to the current position, this is indicated as a common cell Output display. The degree of achievement to the goal is divided in stages, and each stage is expressed and emphasized by changing the expression and using sound and images. Eventually, when the target and the current position approach each other, the cell to which the target belongs matches the cell to which the current position belongs as the previous stage, and the cell to which the target belongs and the cell in the vicinity of the current position match. Since there are a number of approaches that can be set, such as sometimes, these are classified and arranged appropriately and clearly highlighted.

Example 23
When there is a match between the cell related to the target and the cell related to the current position, this common blank is specified when there are two or more common cells. Explicit output display. When cells that are adjacent to the blank that closes the cell to which the target belongs, cells near the target, and the cell that the current position belongs, and cells that are adjacent to the blank that closes the cell near the current position, etc., generate two or more common cells Or when a cell around the target and a cell around the current position generate a common cell. When there are two or more common blanks, they are highlighted and clearly shown.

Example 24
When a cell that overlaps the line connecting the current position and the target and a cell that is adjacent to the blank that forms the course from the current position to the target are classified as cells related to the target, and a cell and a common cell related to the current position are generated This common cell is highlighted. Each mode is highlighted, such as when two or more common cells occur, when a common blank occurs, or when two or more common blanks occur. Explicitly indicate by voice, image, or text.

Example 25
The travel area cells are output and displayed, and the moving speed and moving direction of the moving body are output and displayed as vectors. Cells and vectors are presented in mountains, seas, and airspaces in areas that can travel in the same direction. It is not negligible that the vector changes due to ocean currents and air currents in sea and air. The movement mode is indicated by a vector based on the speed and direction, and the vector and the cell are output and displayed together. Provided as information.

  In Yamano, a cell is calculated and searched using the performance and function of the moving object and the situation of the travel area as travel elements. It is also possible to change the cell by taking weather and anomalies as elements as dynamic information. In the sea area, the shape of the seabed, coastline, ocean current, wind and weather can be used as factors, and the performance, function and skill of the ship can be used as factors. Depending on the scale, it may be difficult to change the vector. In this embodiment, a vector in a unit time in which a vector change is allowed is shown. If a cell is newly formed if there is any change that becomes an obstacle to travel, this information can be used as an element when dynamic information is transmitted, for example, by watching a satellite or the like. When the travel area is an airspace, the cells are shown in three dimensions.

  Since the variability of the vector in unit time differs depending on the aircraft model, the performance of each model is fundamental as a travel factor. Even if the cell itself is the same, it is necessary to change the cell size depending on the model. When an element extracted from dynamic information is a dynamic element and an element extracted from static information is a static element, the cell formed by the static element is weakly related to the performance of the model, The cell formed by the dynamic element corresponds to the vector variability due to the performance of the model. When the variability is excellent, the cell shape is not changed, and when the variability is poor, the cell shape is expanded. There is a need to. This also applies when the travel area is a sea area.

Example 26
When the vectors of the cell and the moving body are presented, an ideal vector that is not obstructed by the cell is calculated and output and displayed. When a cell is searched for and output from a static element and a dynamic element, the vector variability according to the performance of the moving object is put into the element, and a vector that avoids the cell is obtained as an ideal vector. Both the vector and the ideal vector are output and displayed. It is also possible to improve the visibility of the vector image by specifying two vectors when presented by an image and not presenting the cell as an image while the ideal vector is displayed. If a cell is searched for an operation and an ideal vector is obtained and used as a basis, it is not essential to be specifically presented to the user.

[The invention's effect]
As is apparent from the above description, the present invention has the following effects. When the travel area is a region, sea area, or air area, the suitability of the travel area is evaluated against the travel elements such as the purpose, skill, type of mobile, etc. One can easily utilize blanks that close cells as well as avoid cells. Moreover, since the cells are presented in various manners as to how to avoid the presented cells, the route determination is supported as to which cells are avoided and which cells are used. Since the unit band that is not suitable for travel is presented as a cell, the user is freed from reading a map and many stress-induced guidance, and can instantly detect useful basic information. Useful basic information can be extracted, processed, and presented so as not to burden the user. In conventional development, such thoughts and ideas were lacking, and a detailed map and a stressful guide were provided casually. However, according to the present invention, basic information called cells is presented and safety, functionality, and responsiveness are presented. Can be provided in the navigation system. In an embodiment in which an ideal vector and a moving object vector are presented, it is sufficient to set the direction and speed so that the moving object vector matches the ideal vector. Is possible.
