Description

  The present invention relates to a navigation device that searches for various information such as route information and facility information, and more particularly to a navigation device that can easily set search conditions.

  2. Description of the Related Art Conventionally, an in-vehicle navigation system that can flexibly set search conditions for searching for an optimum route for each driver, such as distance priority and time priority, is known (see, for example, Patent Document 1).

  When searching for routes with priority on distance, this in-vehicle navigation system integrates the distance data of each road segment constituting each route, and extracts the route with the minimum sum of the accumulated distance data as the recommended route. .

  In addition, when searching for routes with time priority, this in-vehicle navigation system integrates the required travel time data of each road segment constituting each route, and uses the route with the minimum as a recommended route. Extract.

  Furthermore, this vehicle-mounted navigation system combines time priority or distance priority, and extracts the route that minimizes the total sum as a recommended route while adding up the total of each integrated data.

  Specifically, according to each search condition, a distance coefficient (which is a weighting coefficient multiplied to each distance data when integrating the distance data) or a time coefficient (each required travel when integrating the required travel time data). The weighting coefficient multiplied by the time data) is set, and for example, in the case of a search condition that gives priority to short distance but does not matter about the required travel time, the distance coefficient is increased, In addition, by reducing the time coefficient, the influence of the distance coefficient on the grand total is relatively increased, and then a recommended route that minimizes the grand total is extracted.

JP-A-1-138409

  However, in the in-vehicle navigation system described in Patent Document 1, when setting the value of the distance coefficient or the value of the time coefficient for each search condition, it is necessary to input the values individually, and the operator can select the recommended route.

  The control unit 1 is a computer including a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. For example, the route search means 10, the facility search means 11, and the setting screen display means 12 and the parameter acquisition means 13 are stored in the ROM, and the CPU executes processing corresponding to each means.

  The input unit 2 is a device for inputting various information to the navigation device 100. For example, the input unit 2 is a touch panel, a joystick, a remote controller, an escutcheon button, etc., and sets a destination for a route search, a search condition parameter, etc. Used for

  The “search condition parameter” is a parameter used when the route search unit 10 described later searches for a recommended route, or the facility search unit 11 described later searches for a recommended facility. The length of time required to consider when searching for a route, the length of mileage, the size of the cost (including fuel costs, toll road charges, etc.) or the ease of travel (number of right and left turns, the width of the road, etc.) Or the size of the facility to be considered when searching for the facility to be used, the old and new establishment, the size of the usage fee or the degree of popularity.

  The positioning unit 3 is a device for measuring the position of the vehicle. For example, a GPS (Global Positioning System) receiver receives a GPS signal output from a GPS satellite via a GPS antenna, and based on the received signal. Measure vehicle position (latitude, longitude, altitude). The measurement by the positioning unit 3 may be any method such as independent positioning or relative positioning (including interference positioning), but preferably relative positioning with high accuracy is used. At this time, the vehicle position may be corrected based on outputs of various sensors such as a steering angle sensor, a vehicle speed sensor, and a gyro sensor, and various information received via a beacon receiver or an FM multiplex receiver.

  The storage unit 4 is a device for storing various types of information. For example, the storage unit 4 is a storage medium such as a hard disk or a DVD (Digital Versatile Disk), and includes node positions such as intersections and interchanges, and links (elements connecting the nodes). ), The link cost (the time required to pass the link, the fee, etc.), the toll road toll, etc. are stored in a map information database.

  In addition, the storage unit 4 stores the location (latitude, longitude, altitude), name, usage fee, popularity (number of users, etc.), establishment date or scale of a facility such as an accommodation facility, a restaurant, or an amusement park. Stores a facility information database that systematically stores information such as the number of persons accommodated, the number of parking spaces, and the exclusive area.

  The display unit 5 is a device for displaying various kinds of information, such as a liquid crystal display or an organic EL display, and sets a destination setting screen and search condition parameters based on a control signal from the control unit 1. A positioning map (to be described later), map data, or a variety of information such as a recommended route searched by the route searching means 10 described later or a recommended facility searched by the facility searching means 11 described later is displayed.

  The voice output unit 6 is a device for outputting various information as voices. For example, the voice output unit 6 is an in-vehicle speaker and relates to a recommended route searched by the route search unit 10 described later and a recommended facility searched by the facility search unit 11 described later. Output voice guidance.

  Next, various units included in the control unit 1 will be described.

  The route search means 10 is a means for searching for a recommended route. For example, the vehicle position (latitude, longitude, altitude) measured by the positioning unit 3 and the location information of the destination input via the input unit 2 ( Based on the latitude, longitude, altitude) and the map information database stored in the storage unit 4, an optimum route from a predetermined position (for example, the current position of the vehicle) to the destination is searched.

  The route search means 10 searches for the shortest route using the Dijkstra method as a route search algorithm when, for example, the shortest travel distance is set according to the search condition parameter.

  In addition, when the search condition parameter is set so as to place importance on the short time required, the route search means 10 determines the route that can reach the destination earliest in time based on the legal speed, the traffic jam situation, and the like. If the search is set to emphasize low cost by the search condition parameter, the route that does not use the toll road is searched, or the ease of driving is improved by the search condition parameter. When the priority is set, a search is made for a route constituted by an intersection, a junction or a route with a small number of right / left turns or a wide road.

  Further, the route search means 10 searches for a route while combining each search condition parameter such as travel distance, required time, cost, or ease of travel.

  For example, each of the search condition parameters has five levels, the “travel distance” is the first level (which means that it is the highest level and the shortest distance is requested as the search condition), and “cost” is Assume a case where it is set to the third level (which is a standard level, meaning that a standard cost is required as a search condition).

  In this case, the route search means 10 is a common-sense route candidate that does not include an unnatural right / left turn that is searched based on a predetermined search condition. .)), The five route candidates are arranged in the order of the shortest “travel distance”, and the top 20% (corresponding to the first level. In this case, one route) is selected. . On the other hand, the route search means 10 arranges the above-mentioned five route candidates in descending order of “cost”, and selects 20% of the route candidates (corresponding to the third level. In this case, one route candidate). select. Then, when there is an overlapping route candidate between the route candidate selected based on the “travel distance” and the route candidate selected based on the “cost”, the route search means 10 selects the overlapping route candidate as a recommended route. Output as.

  In addition, when there are a plurality of overlapping route candidates, the route search unit 10 displays the plurality of route candidates as recommended routes on the display unit 5 and then allows the operator to select one of them. It may be possible to select one route candidate automatically based on a predetermined selection algorithm, and when there is no overlapping route candidate, a message “No recommended route” is displayed. You may make it display on the part 5. FIG.

  The search condition parameter may have an allowable range. For example, the “travel distance” is set with a range from the first level (the highest level) to the third level, and the “cost” is set. It is assumed that the third level (standard level) to the fifth level (lowest level) are set with a width.

  In this case, the route search means 10 first searches for a plurality of route candidates (for example, 5 routes), and then arranges these 5 route candidates in order of “traveling distance” in ascending order, with the top 60% (Corresponding to the first level to the third level. In this case, three ways) route candidates are selected. On the other hand, the route search means 10 arranges the above-mentioned five route candidates in descending order of “cost” and selects the lower 60% (corresponding to the third to fifth levels. In this case, three) route candidates. select. Then, when there is an overlapping route candidate between the route candidate selected based on the “travel distance” and the route candidate selected based on the “cost”, the route search means 10 selects the overlapping route candidate as a recommended route. Output as.

  The route search means 10 displays the finally selected recommended route on the screen of the display unit 5 so that the recommended route can be identified from other routes so that the operator can easily check the recommended route. The voice guidance along the line is output from the voice output unit 6 to assist the driving by the operator.

  The facility search means 11 is a means for searching for a recommended facility. For example, the vehicle position (latitude, longitude, altitude) measured by the positioning unit 3 and the type of the search target facility input via the input unit 2 ( For example, there is an accommodation facility.) And a facility in the vicinity of a predetermined position (for example, the current position of the vehicle) is searched based on the facility information database stored in the storage unit 4.

  For example, if the facility search means 11 is set so as to place importance on the size of the facility according to the search condition parameter, the facility search means 11 searches for a facility having a predetermined number of persons or more, and determines the newness of the facility by the search condition parameter. If it is set to be emphasized, it will search for facilities whose elapsed period after establishment is less than the predetermined period, and if it is set to emphasize low facility usage charges by the search condition parameter, the usage fee will be If the facility is set to search for a facility with a price less than a predetermined fee, or to place importance on the popularity of the facility according to the search condition parameter, the number of users of the facility (for example, the number of monthly users). Search for facilities with more than a certain number of people.

  Furthermore, the facility search unit 11 searches for a facility in combination with each search condition parameter such as the size of the facility, the new and old establishments, the usage fee or the popularity, like the route search unit 10.

  For example, each of the search condition parameters has five levels, the “facility scale” is the first level (which means the highest level, which requires the maximum scale as the search condition), “ Assume that “new and old” is set to the third level (which is a standard level, meaning that standard newness is requested as a search condition).

  In this case, the facility search unit 11 first searches for a plurality of facility candidates (for example, 5 types), and arranges these 5 types of facility candidates in descending order of scale, similar to the route search unit 10. The top 20% (in this case, one) facility candidates are selected. On the other hand, the facility search means 11 arranges the above five facility candidates in the order of establishment date, and selects the center 20% (in this case, one) facility candidates. Then, the facility search means 11, when there are overlapping facility candidates in the facility candidate selected based on the “scale of facility” and the facility candidate selected based on “new and old”, the overlapping facility candidate Is output as a recommended facility.

  In addition, when there are a plurality of overlapping facility candidates, the facility search unit 11 causes the display unit 5 to display a plurality of facility candidates as recommended facilities and causes the operator to select one of them. It may be possible to select one facility candidate automatically based on a predetermined selection algorithm, and when there is no overlapping facility candidate, a message of “no recommended facility” is displayed. You may make it display on the part 5. FIG.

  The search condition parameter may have an allowable range. For example, the “facility scale” is set with a range from the first level (the highest level) to the third level, Assume that “new and old” is set with a width from the third level (standard level) to the fifth level (lowest level).

  In this case, the facility search means 11 first searches for a plurality of facility candidates (for example, 5 types), and then arranges these 5 types of facility candidates in descending order of scale, and the top 60% (in this case) (3 types) of facility candidates. On the other hand, the facility search means 11 arranges the above five facility candidates in the order of establishment date, and selects the facility candidates of the lower 60% (in this case, three). Then, the facility search means 11 determines the recommended facility candidate when there is an overlapping facility candidate between the facility candidate selected based on the scale and the facility candidate selected based on the new and old date of establishment. Output as.

  The setting screen display means 12 is a means for displaying a screen for setting search condition parameters. For example, the positioning map M is displayed on the display unit 5 when the navigation device 100 is activated, and the operator can easily set the search condition parameters. And set it efficiently.

  Note that the setting screen display unit 12 may pop up the positioning map M in a partial area of the display unit 5 in response to a predetermined operation input such as pressing of a search condition setting button, and the positioning map M is displayed on the display unit 5. You may display on the whole display screen.

  FIG. 2 is a display example of the positioning map M displayed on the display unit 5 and shows a state in which the positioning map M is pop-up displayed in the right half area of the display unit 5.

  FIG. 2 shows a positioning map M composed of two-dimensional coordinates in which the search condition parameter “required time” is arranged on the vertical axis and the search condition parameter “cost” is arranged on the horizontal axis. The closer to the “Quick” display direction), the higher the “Required Time” level (meaning that the shorter required time is important), and the lower part of the vertical axis (“Comfort” is displayed). It indicates that the level of “required time” is lower as it is closer to (the direction in which the image is displayed) (it means that it is possible to make a detour, or that importance is attached to the length or comfort of the person who wants to enjoy the scenery).

  In addition, in FIG. 2, the cost level becomes higher as it approaches the right side of the horizontal axis (the direction in which “Rich” is displayed) (priority is given to toll roads, etc.). ), The closer to the left side of the horizontal axis (the direction in which “Economy” is displayed), the lower the level of costs (meaning that saving is important, such as avoiding toll roads). Indicates.

  The parameter acquisition unit 13 is a unit for acquiring information on search condition parameters based on a series of operation inputs by the operator. For example, the coordinates at which the operator's finger contacts via the input unit 2 (touch panel) are obtained. The level of the search condition parameter is acquired based on the detected coordinate position.

  In addition, the parameter acquisition unit 13 determines the allowable range of the search condition parameter centered on the level corresponding to the coordinates with which the operator's finger is in contact according to the contact time during which the operator's finger is in contact with the touch panel. .

  “A series of operation inputs” refers to operation inputs that can be collectively, for example, an operation input consisting of a series of actions of bringing a finger into contact with the touch panel, continuing the contact for a predetermined period, and releasing the finger from the touch panel, or In addition, an operation input including a series of actions of bringing a finger into contact with the touch panel, dragging, and releasing the finger from the touch panel is included.

  FIG. 3 is a diagram for explaining a process (hereinafter referred to as “search condition parameter setting process”) in which the navigation apparatus 100 sets search condition parameters based on a series of operation inputs of the operator. The index point P (X = 2, Y = 2) in the upper right area of the positioning map M is pressed by the left index finger of the left hand. 3A shows the state of the positioning map M immediately after being pressed, and FIG. 3B shows the state of the positioning map M after the pressing (contact between the finger and the touch panel) is continued for a predetermined period. Indicates.

  The unit used to express the coordinate points is the level of the search condition parameter. In this case, the search condition parameters “required time” and “cost” are each composed of 11 levels, which are at the top of the figure. Corresponds to the first level of “required time”, and the rightmost part of the figure corresponds to the first level of “cost”. Further, the coordinate point P (X = 2, Y = 2) is a point where both “required time” and “cost” are at the fourth level.

  As shown in FIG. 3A, the setting screen display means 12 displays a circle C1 having a predetermined radius (for example, three levels) when the coordinate point P is pressed, and the “required time” is the first level (the highest level). The upper limit is set within the allowable range from the sixth level (one level below the horizontal axis), and “cost” is the first level (rightmost) to the sixth level (one level left from the vertical axis). ) Is displayed within the allowable range.

  Further, as shown in FIG. 3B, the setting screen display means 12 reduces the radius of the circle C1 by one level when the coordinate point P is continuously pressed for a predetermined period (for example, 2 seconds). Circle C2 is displayed, “Time required” is set within the allowable range of the second level (level one level below the top) to the fifth level (level on the horizontal axis), and “cost” is the second level The state set in the allowable range of (the level 1 level left from the rightmost part) to the fifth level (level of the vertical axis) is displayed.

  Further, the setting screen display means 12 may display a circle having a further reduced radius when the coordinate point P is continuously pressed for a predetermined period (for example, 2 seconds).

  After that, the parameter acquisition means 13 assumes that the setting of the search condition parameters “required time” and “cost” is completed when the index finger of the left hand of the operator has left the touch panel, and the circle displayed at that time is displayed. Corresponding “required time” and “cost” allowable ranges are acquired, and the acquired allowable ranges are output to the route search means 10.

  The setting screen display means 12 may first display a circle with a small radius (for example, one level), and gradually increase the radius of the circle as the contact time increases. When the maximum (for example, 4 levels) is reached, the radius of the circle may be temporarily returned to the minimum (1 level), and the increase of the radius may be resumed for circulation. Note that the radius may be gradually decreased, and when the radius becomes the minimum, the radius of the circle is once returned to the maximum, and the reduction of the radius may be resumed for circulation.

  Thus, since the navigation apparatus 100 sets the search condition parameters while displaying the positioning map M on the display unit 5, it is possible to simultaneously acquire the allowable ranges of the two search condition parameters by a series of operation inputs. Setting of search conditions by the operator can be simplified or made efficient.

  Next, another method in which the parameter acquisition unit 13 acquires information related to the search condition parameter will be described with reference to FIG.

  4 (A) to 4 (C) each show the state of the positioning map M after the depression is continued for a predetermined period, and the setting screen display means 12 sets the radius of the circle as shown in FIG. 3 (B). Instead of gradually reducing, only the radial component parallel to the horizontal axis direction is reduced (see FIG. 4A), or only the radial component parallel to the vertical axis direction is reduced (FIG. 4B). Alternatively, only a radial component parallel to a predetermined angle (for example, 135 °) direction may be reduced (see FIG. 4C).

  In this case, FIG. 4A shows that the “required time” is set within an allowable range from the first level (top) to the sixth level (a level one level lower than the horizontal axis) and “cost” is the first. FIG. 4B shows a state where the four levels (two levels to the right of the vertical axis) are set, and FIG. 4B shows that the “required time” is set to the fourth level (two levels above the horizontal axis), and , “Cost” is set in an allowable range from the first level (rightmost part) to the sixth level (one level left from the vertical axis).

  FIG. 4C shows that the “required time” is set within an allowable range from the first level (top) to the sixth level (a level one level below the horizontal axis), and “cost” is the first. The recommended route by the route search means 10 based on the condition shown in FIG. 4C is shown in a state set within an allowable range of level (rightmost part) to sixth level (one level left from the vertical axis). This means that the search target is limited to the case where the levels of the two search condition parameters correspond to each other as in the case where “required time” is the first level and “cost” is the first level.

  The setting screen display means 12 may reduce the radius component parallel to the vertical axis direction after reducing only the radial component parallel to the horizontal axis direction, or only the radius component parallel to the vertical axis direction. Then, the radius component parallel to the horizontal axis direction may be reduced.

  Next, a process of generating a circle C3 indicating the allowable range of the search condition parameters “required time” and “cost” on the positioning map M by a series of operation inputs will be described with reference to FIG.

  FIG. 5A shows a state in which the operator touches one point on the touch panel with the index finger of the left hand and performs a drag operation so as to draw a circle in the upper right area of the positioning map M.

  FIG. 5B shows a line segment drawn by the operator's drag operation, and the operator notifies the navigation device 100 of the end of drawing by releasing his finger from the touch panel at this point.

  FIG. 5C shows a circle C3 whose shape or size is adjusted based on the shape or size of a line segment drawn by the operator through a drag operation.

  As described above, the navigation device 100 collectively sets the permissible ranges of the plurality of search condition parameters based on the operation input including a series of actions of bringing a finger into contact with the touch panel, dragging, and releasing the finger from the touch panel. Since it is acquired, the setting of the search condition by the operator can be simplified.

  Next, the flow of search condition parameter setting processing will be described with reference to FIG. FIG. 6 is a flowchart showing the flow of search condition parameter setting processing.

  First, the control unit 1 of the navigation device 100 causes the setting screen display unit 12 to display the positioning map M (see FIG. 2) on the display unit 5 when the navigation device 100 is activated (step S1).

  Thereafter, the control unit 1 waits until an operation input by the operator is performed while monitoring the output of the input unit 2 (touch panel) (step S2).

  Thereafter, when it is detected that the operator's finger touches the touch panel based on the output of the touch panel (YES in step S2), the control unit 1 centers on the coordinate point corresponding to the position where the operator's finger touches. The circle having a predetermined radius (for example, three levels) is displayed on the display unit 5 (step S3).

  Then, the control part 1 increments the value of the contact timer memorize | stored on RAM (step S4). This is to measure the time for which the contact continues.

  Thereafter, the control unit 1 compares the value of the contact timer with the threshold value T (step S5), and when the value of the contact timer is equal to or greater than the threshold value T (YES in step S5), the setting screen display means 12 The radius of the currently displayed circle is reduced by a predetermined level (for example, one level), the contact timer is reset (step S6), and it is determined whether or not the operator's finger has left the touch panel (step S6). S7).

  The reason for reducing the radius of the circle is to narrow the allowable range of the search condition parameter, and the reason for resetting the contact timer is to measure the next timing to reduce the radius of the circle.

  When the value of the contact timer is less than the threshold T (NO in step S5), the control unit 1 moves the operator's finger away from the touch panel without reducing the radius of the circle or resetting the contact timer. It is determined whether or not (step S7).

  Thereafter, the control unit 1 repeatedly executes the processes of steps S4 to S6 while monitoring the output of the touch panel until the operator's finger leaves the touch panel (NO in step S7), and the operator's finger leaves the touch panel. If this is detected (YES in step S7), the parameter acquisition means 13 acquires the allowable range of the search condition parameter “required time” and the allowable range of the search condition parameter “cost” at that time in a lump ( Step S8).

  In addition, the setting screen display unit 12 sets another search condition parameters “travel distance” and “ease of travel” when the search condition parameters “required time” and “cost” are set. A positioning map may be displayed.

  Thereafter, the navigation device 100 searches for a recommended route by the route search unit 10 based on the acquired setting of the search condition parameter. However, the navigation device 100 acquires the setting of the search condition parameter using the same positioning map, and the facility search unit 11 A recommended facility may be searched.

  With the above configuration, the navigation device 100 sets an allowable range for each search condition parameter via a simple and efficient operation input, and executes a search based on the allowable range for each search condition parameter. It is possible to promptly present information according to a person's wishes.

  Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the present invention. Can be added.

  For example, in the above-described embodiment, the navigation device 100 changes the shape or size of the circle indicating the allowable range of the search condition parameter according to an increase in the time during which the operator's finger is in contact with the touch panel. Instead of displaying a rectangle, the allowable range of the search condition parameter may be indicated.

  In addition, the navigation device 100 outputs a sound or a sound corresponding to the change from the sound output unit 6 while changing the shape or size of the circle or quadrangle, and the current shape or The operator may be able to grasp the size.

  In addition, the navigation apparatus 100 sets the allowable range of the search condition parameter via another input device, such as setting the allowable range of the search condition parameter based on the cursor position moved with the mouse and the duration of the mouse button press. You may make it set.

  Further, the navigation device 100 changes the shape or size of a circle indicating the allowable range of the search condition parameter according to the time that the operator's finger is in contact with the touch panel, but the touch panel has a mechanism for detecting the contact pressure. When provided, the shape or size of a circle indicating the allowable range of the search condition parameter may be changed according to the contact pressure.

  Further, the navigation device 100 uses a function of changing the shape or size of the circle according to the time during which the operator's finger is in contact with the touch panel when inputting the rough position of the destination. Also good.

  For example, when setting a far destination, the navigation device 100 temporarily determines a rough position of the destination using a circle having a relatively large radius, and performs a rough route search based on the temporarily determined destination. Execute early. Then, when the operator can spend time for detailed setting of the destination, the detailed position of the destination is determined by using a circle having a relatively small radius, and the detailed destination is determined. The original detailed route search is executed based on the ground.

  Thereby, even when there is no time for detailed setting of the destination, the navigation device 100 temporarily sets the destination easily and efficiently, and executes meaningful route search and route guidance at an early stage. be able to.
