Description

  The present invention relates to an electronic device for reporting information related to toll road discounts.

  As a device that guides the driver on whether to apply a discount while traveling on a toll road, on the toll road such as an expressway, the conditions to be discounted are stored, and the discount is applied when passing the next interchange In the case where there is no such thing, it is known that it is possible to know whether or not a discount is applied by giving guidance such as “Next is the last interchange to which commuting discount is applied” (Patent Document 1).

  In addition, there is known an apparatus for searching for a guidance route to which a discount is applied when searching for a route to a destination (Patent Documents 2 and 3).

JP 2008-225966 A JP 2007-3372 A JP 2007-271181 A

  In the technique described in Patent Document 1, since it is not notified that the vehicle actually travels on the highway and is not before the interchange immediately before the discount condition is not satisfied, the exit interchange to which the discount is applied is not known until that time. There is a problem.

  In addition, the techniques described in Patent Documents 2 and 3 have a problem that information about discounts is not notified when route search is not performed. In the first place, there is a problem that it cannot be realized by an inexpensive device without a route search function.

  Therefore, the present invention can notify the driver, etc., of the exit interchange where the fee discount exists at an early stage and can be aware of it, and can be used more reliably than before. It is an object to provide a good electronic device.

  In order to achieve the above-described object, the electronic device according to the present invention includes (1) storage means for storing information on the farthest exit interchange where a fee discount exists from the entrance interchange for each entrance interchange on the toll road; An entry detection means for detecting entry into the entrance interchange, and when entry into the entrance interchange is detected by the entry detection means, there is a fee discount from the entrance interchange based on information stored in the storage means Control means for performing control to output information on the farthest exit interchange.

  According to such a configuration, when an entry to the entrance interchange is detected, information on the farthest exit interchange where a fee discount exists is output from the entrance interchange. Therefore, the farthest exit interchange where a fee discount exists can be notified at an early stage. You can also be aware of the farthest exit interchange where there is a discount. Therefore, it becomes possible to receive discount application more reliably than before.

  In particular, this output is preferably performed immediately after the entry is detected. Further, such a configuration can be realized as an additional function of a navigation device having a route guidance function, for example, but is suitable for an inexpensive device that does not have a route guidance function, for example.

  It should be noted that a plurality of pieces of information regarding the farthest exit interchange for which there is a charge discount from the entrance interchange may be stored and output. For example, for each road name to which the exit interchange is connected, information on the farthest exit interchange for which there is a fee discount from the entrance interchange may be stored and output, or the fee from the entrance interchange for each direction to which the exit interchange belongs. Information on the farthest exit interchange where discounts exist may be stored and output, or information on the farthest exit interchange where there is a fee discount is stored and output from the entrance interchange for each discount condition. Also good.

  (2) a road type determination unit that determines whether the vehicle is traveling on a toll road or a general road; and an entrance approach detection unit that detects an approach to the entrance interchange. When it is determined that the road type determination unit is traveling on a general road and the approach to the entrance interchange is detected by the entrance approach detection unit, the entrance interchange is based on the information stored in the storage unit. It may be configured to control to output information on the farthest exit interchange where there is a toll discount.

  According to such a configuration, even when driving on a general road that is not a toll road, when approaching the entrance interchange, information on the farthest exit interchange where there is a fee discount is output from the entrance interchange. The Therefore, even when traveling on a general road, it is possible to recognize the farthest exit interchange where there is a fee discount from the entrance interchange in the vicinity. Therefore, for example, even those who do not normally use toll roads can be aware of the farthest exit interchange where there is a toll road price discount.

  (3) The storage means stores information relating to the exit interchange in association with information relating to the name of the exit interchange and information relating to the name of the road to which the exit interchange is connected. It is good to set it as the structure which outputs the information regarding a name with the information regarding the road name which the said exit interchange connects.

  According to such a configuration, the information about the name of the exit interchange is output together with the information about the name of the road to which the exit interchange is connected. It becomes difficult to occur. For example, the driver can easily determine whether or not the information relates to an interchange on the road that he / she intends to travel after hearing the road name. In this way, it is possible to notify the exit interchange that is subject to discount at an early stage, to be aware of the exit interchange that is subject to discount, and to be able to receive discounts more reliably than before. .

  In addition to the road name, if the exit interchange is an interchange that belongs to the upper or lower line, or if the exit interchange is in which direction as seen from the entrance interchange, Good.

  (4) The storage means stores information relating to the name of the exit interchange and information relating to the direction to which the exit interchange belongs as information relating to the exit interchange, and the control means stores the name of the exit interchange. It is good to be the structure which outputs the information regarding every information regarding the direction to which the said exit interchange belongs.

  In this way, information about the name of the exit interchange is output for each piece of information about the direction to which the exit interchange belongs, so for example, it is possible to solve the problem of not knowing which interchange it is by listening to the name of the exit interchange it can. Further, when a plurality of farthest exit interchanges are stored in one direction, information on the name of the exit interchange is output for each direction, which is easy to understand and easy to use.

  (5) The storage means stores information relating to the name of the exit interchange and information relating to discount conditions for the exit interchange as information relating to the exit interchange, and the control means stores the name of the exit interchange. It is good to be the structure which outputs the information regarding every information regarding the discount conditions of the said exit interchange.

  In this way, the information about the name of the exit interchange is output for each piece of information about the discount condition of the exit interchange, so it is possible to easily grasp under which discount conditions the exit interchange is discounted. In addition, when a plurality of farthest exit interchanges are stored in one discount condition, information on the name of the exit interchange is output for each discount condition, which is easy to understand and easy to use.

  (6) The control means does not satisfy the discount condition among the information about the farthest exit interchange where a fee discount exists from the entrance interchange when the entrance detection means detects entry into the entrance interchange. It is preferable that the information regarding the exit interchange is not output.

  In this way, when entering the entrance interchange, information related to the exit interchange that satisfies the discount condition is notified, and information related to the exit interchange that does not satisfy the discount condition is not notified. Therefore, only the farthest exit interchange that satisfies the discount condition can be notified to the driver or the like, and the driver can be made aware of it. Therefore, it is possible to provide an easy-to-use electronic device that can be more reliably discounted than before.

  Whether the discount condition is satisfied or not satisfied may be determined immediately before the output. This determination may be performed based on, for example, information obtained by receiving an external radio wave, information obtained from a vehicle, information obtained from a sensor provided in the electronic device, or the like.

  Discount conditions may be incorporated during processing in the control means, for example. For example, discount conditions may be stored in the program, and information regarding each exit interchange and information regarding fees from each entrance interchange to each exit interchange may be stored in a recording medium or the like. The storage means may store, for example, discount conditions, information about each exit interchange, and information about a fee from each entrance interchange to each exit interchange. For example, the storage means may be configured as a relational database. And a control means is good to set it as the structure which acquires and outputs the information regarding the farthest exit interchange which satisfy | fills discount conditions based on the correlation in this memory | storage means.

  Further, for example, the storage unit may store a plurality of discount conditions, and the control unit may perform control to output information regarding the farthest exit interchange that satisfies the discount condition for each discount condition. . According to such a configuration, the driver can easily determine which discount condition should be used, and at which interchange to get off. Therefore, the exit interchange to be discounted can be notified at an early stage, the exit interchange to be discounted can be recognized, and the discount can be applied more reliably than before.

  (7) The control means, as the discount condition, that the distance from the entrance interchange to the exit interchange is a predetermined distance or less, that the entry time to the entrance interchange is within a prescribed range, and that the exit time from the exit interchange is predetermined. It may be configured to output information relating to at least one of the following ranges and that the route from the entrance interchange to the exit interchange is a route within a predetermined range.

  (8) Output target discount condition setting means for setting a discount condition to be output among the discount conditions is provided, and the control means corresponds to the output target discount condition set by the discount condition item setting means. May be configured to output. According to such a configuration, useless notification can be suppressed. Therefore, discounts can be applied more reliably than before.

  For example, in the case of discount conditions that apply only to ordinary vehicles, it is not necessary to notify the driver of a large vehicle of information on exit interchanges to which the discount conditions are applied. Therefore, for example, information on each exit interchange and information on the charges from each entrance interchange to each exit interchange are stored separately for ordinary vehicles and large vehicles, and based on user operations, etc. Output target discount condition setting means for setting either one is provided. And a control means outputs only what satisfy | fills this set discount condition.

  (9) The control means stores information related to the entrance interchange detected by the entry detection means and information related to the exit interchange that has performed the output control, and discount conditions from the stored entrance interchange When the farthest exit interchange satisfying the condition has changed from the stored exit interchange, it is preferable to perform control to output information on the exit interchange after the change.

  According to such a configuration, when the exit interchange satisfying the discount condition is changed from the previously notified one, information on the exit interchange satisfying the current discount condition is output again. Therefore, it is possible to ensure that a discount is applied.

  By the way, in (1), the case where the entry to the highway is detected may be, for example, the case where it is detected that it is on the route to the main road of the highway, or the case where the vehicle has entered the main road of the highway. May be detected. Further, (10) may be used.

  (10) The entry detection means performs a first detection at a point on the route entering the main line at the entrance interchange and before branching in the upper or lower direction of the main line, and either the upper or lower of the main line. A second detection is performed at a point after branching in the direction of, and the control means performs a control to perform the output by the second detection after the control to perform the output by the first detection; Good.

  In this way, if you go in the upward direction before the branch of the upper and lower lines of the toll road, to which interchange the discount is applied, if you go in the downward direction, to which interchange It is possible to know whether the discount is applied, and after the branch, it is possible to know up to which interchange the discount is applied in the direction of driving. Therefore, it is possible to effectively recognize the exit interchange to be discounted.

  (11) An exit approach detection unit that detects approach to the farthest exit interchange that satisfies the discount condition, and an exit detection unit that detects exit from the toll road to a general road, wherein the control unit includes: The farthest exit satisfying the discount condition by the approach detecting means after the entry detecting means detects the entrance to the entrance interchange and until the exit detecting means detects the exit from the toll road to the general road. When approaching the interchange, control to output an approach warning may be performed.

  In this way, it is possible to prevent inadvertently forgetting to leave at the farthest exit interchange that satisfies the discount condition, and after the exit detection means detects the exit from the toll road to the general road, Even when approaching the exit interchange from the general road side, the approach warning is not notified. For example, if you exit from the exit interchange that is just before the farthest exit interchange that satisfies the discount condition and then exit the general road, you will pass through the general road and approach the farthest exit interchange that meets this discount condition. Can be prevented from being notified.

(12) An update means for updating the contents of the storage means may be provided. The updating unit may input an instruction from the driver or the like to update the contents of the storage unit, or may acquire and update new information by communication or the like. The information to be updated may be the information described so far. According to such a configuration, information on the latest interchange can be notified along with the latest discount conditions and the like.
(13) In addition, it can implement | achieve as a program for making a computer implement | achieve the function as a control means in the electronic device in any one of (1)-(12).

  According to the present invention, it is possible to notify a driver or the like of an exit interchange to be discounted at an early stage, to be aware of the exit interchange to be discounted, and to receive a discount more reliably than before. It is possible to provide an easy-to-use electronic device that can be used.

Further, an adapter jack 9 is disposed on one side surface of the case body 1, and a power switch 10 and a DC jack (not shown) are disposed on the other side surface. A speaker 20 is also built in the case body 1. In the present embodiment, the display unit 5 is a 2.4 inch small liquid crystal display, and the height H on the rear side of the case body 1 on which the display unit 5 is mounted is set to be higher than the height H0 of other parts. Yes.

  As shown in FIG. 2, the infrared communication device 7 transmits and receives data to and from a communication device incorporating an infrared communication device such as a mobile phone 12. The adapter jack 9 is a terminal for connecting the memory card reader 13. By connecting the memory card reader 13 to the adapter jack 9, data stored in the memory card 14 attached to the memory card reader 13 can be taken in. More specifically, the data stored in the memory card 14 includes update information such as information on a new target (position information including longitude and latitude, type information, etc.), and the update information passes through the control unit 18. Thus, the data is stored (downloaded) in the database 19 built in the apparatus, and the data is updated. The function of the memory card reader 13 may be configured to be built in the main body case 1.

  The database 19 is a nonvolatile memory (for example, EEPROM) in the microcomputer of the control unit 18 or externally attached to the microcomputer. In the database 19, information related to a certain target is registered at the time of shipment, and data and the like regarding the target added after that can be updated as described above. Data update can also be performed via the infrared communication device 7.

  The DC jack is for connecting a cigar plug cord (not shown), and is connected to a cigar socket of the vehicle via the cigar plug cord so that power can be supplied. The wireless receiver 15 receives incoming radio waves having a predetermined frequency. The remote control receiver 16 performs data communication with a remote control (portable device: handset) 17 by infrared rays and performs various settings for the device. The switch unit 3 is also connected to the control unit 18 (not shown) so that the same setting as the remote controller 17 can be performed. The remote controller 17 includes a standby switch button, a setting button, a selection button, a cancel button, an enter button, and up / down / left / right cross buttons.

  The control unit 18 includes a microcomputer including a ROM, a RAM, a non-volatile memory, an I / O, and the like. The various input devices (the GPS receiver 8, the microwave receiver 4, the wireless receiver 15, the remote control reception). Predetermined processing is executed based on information input from the device 16, the memory card reader 13, and the infrared communication device 7), and a predetermined alarm / message is output using the output device (display unit 5, alarm lamp 6, speaker 20). Is output. Note that these basic configurations can be basically the same as the conventional ones.

  The functions of the radar detector of the present embodiment are realized by being stored on the EEPROM of the control unit 18 as a program executed by the computer included in the control unit 18 and executed by the computer included in the control unit 18.

  Functions realized by the computer by the program of the control unit 18 include a standby screen display function, a radar scope display function, a GPS alarm function, a radar wave alarm function, a radio alarm function, and a function for informing traffic rules.

  The standby screen display function is a function for displaying the speed, latitude, longitude, and altitude of the host vehicle detected by the GPS receiver 8, as shown in FIG. As shown in FIG. 3 (b), the radar scope display function is a position where a target within a predetermined range (for example, within a range of about 1 km) from the current position detected by the GPS receiver 8 is stored in the database 19. This is a function of searching based on information and displaying the relative positional relationship between the vehicle position and the position of the target on the display unit 5. In FIG. 3B, “W” on the left side indicates the west, “E” on the right side indicates the east, and “N” on the upper side indicates the north direction, and the horizontal line connecting “W” and “E” and “N” The icon at the intersection of the vertical line extending downward from "" indicates the vehicle position. Icons having characters such as “L”, “RD”, “P”, and “N” indicate the type and position of the target. When pressing of a standby switching button provided on the remote controller 17 is detected during execution of the standby screen display function as shown in FIG. 3A, the radar scope display function is switched to as shown in FIG. Further, when pressing of the standby switch button provided on the remote controller 17 is detected during execution of the radar scope display function, processing for switching to the standby screen display function is performed.

  The control unit 18 performs a GPS alarm function, a radar wave alarm function, a radio alarm function, a fuel consumption display function, and a traffic rule notification according to an event that occurs during execution of the standby screen display function or the radar scope display function. The process which implement | achieves each function of these is performed.

  The GPS alarm function obtains the distance between both of the latitude and longitude of the target stored in the database 19 and the latitude and longitude of the current position detected by the GPS receiver 8 during execution of the standby screen display function or the radar scope display function. When the calculated distance is a predetermined distance (for example, within 500 m), this is displayed on the display unit 5 and a sound indicating that is output from the speaker 20. For example, during the execution of the standby screen display function of FIG. 3A or the radar scope function of FIG. 3B, the target “L” (indicating a loop coil radar) and the vehicle position at the top in the figure As shown in FIG. 3C, the schematic diagram or the photograph data of the target loop coil is read from the database 19 and displayed on the display unit 5 as shown in FIG. The stored voice data is read out and an approach notification is output from the speaker 20 to output a voice saying “500m ahead, loop coil”. During sound output, the alarm lamp 6 is turned on.

  These targets include radar, speed limit switching points, control areas, inspection areas, parking monitoring areas, N systems, traffic monitoring systems, intersection monitoring points, signal ignore suppression systems, police stations, accident-prone areas, and on-vehicle targets High-frequency area, sudden / continuous curve (highway), branch / merge point (highway), ETC lane advance guidance (highway), service area (highway), parking area (highway), highway oasis (highway) , Smart interchange (highway), PA / SA petrol station (highway), tunnel (highway), highway radio reception area (highway), prefectural border notice, roadside station, viewpoint parking, etc. Type information of target, latitude / longitude information indicating its position, and data of schematic diagram or photo displayed on display unit 5 Stored in the database 19 in association with the audio data and.

  The radar wave warning function is used when the microwave receiver 4 detects a signal corresponding to a microwave in a frequency band emitted from a velocity measuring device (mobile radar or the like (hereinafter simply referred to as “radar”)). This is an alarm function for displaying an alarm screen on the display unit 5 and outputting an alarm sound from the speaker 20. For example, when a microwave in a microwave frequency band emitted by a radar is detected by the microwave receiver 4, as shown in FIG. 4, a schematic diagram or a photograph of the radar stored in the database 19 is displayed on the display unit 5. While being displayed as an alarm screen, the voice data stored in the database 19 is read out and a voice “Radar. Speed attention” is output from the speaker 20. During sound output, the alarm lamp 6 is turned on.

The wireless alarm function is a function for issuing an alarm so that the wireless receiver 15 does not interfere with traveling or the like when a radio wave emitted by an emergency vehicle or the like is received. In the radio alarm function, enforcement radio, car radio, digital radio, special radio, police radio, police phone, police radio, wrecker radio, heli tele radio, fire helicopter radio, fire fight radio, emergency radio, expressway radio , Scan the frequency of the security radio, etc., and when the radio is received at the scanned frequency, a schematic diagram showing that the radio corresponding to the frequency stored in the database 19 for each radio type is received as an alarm screen While displaying on the display part 5, the audio | voice data memorize | stored for every radio | wireless classification in the database 19 are read, and the alarm sound which shows the radio | wireless classification from the speaker 20 is output. For example, when a control radio is received, a voice is output like “control radio. Speed attention”. During sound output, the alarm lamp 6 is turned on.
In addition to these functions, the radar detector of this embodiment includes a discount target interchange notification function. Hereinafter, a method for realizing this function will be described.

  The database 19 includes an exit inter information table and a discount information table.

  The exit interchange information table is a table that stores the exit interchange name and the location information (latitude and longitude) of the exit interchange in association with each other. In the exit interchange information table, the exit interchange name and the location information of the exit interchange store information on exit interchanges of all toll roads, including exit interchanges that are not discounted.

  As shown in FIG. 5, the discount information table stores information on the farthest exit interchange where there is a fee discount from the entrance interchange for each entrance interchange on the toll road. Specifically, information on the entrance interchange, discount conditions, and information on the exit interchange satisfying the discount conditions from the entrance interchange are stored in association with each other in a table format.

  As information about the entrance interchange, the name of the entrance interchange and the position information (latitude and longitude) of the point on the entrance road of the entrance interchange are stored. As the latitude and longitude, for example, the position at which the vehicle enters a 30 m toll road from the toll gate is used.

  As discount conditions, discount condition contents and range contents are stored. The details of the discount conditions are that the distance from the entrance interchange to the exit interchange is a predetermined distance or less, that the entry time to the entrance interchange is within a prescribed range, that the exit time from the exit interchange is within a prescribed range, and that the entrance interchange It includes information for specifying that the route from the exit to the exit interchange is a route within a predetermined range, and is configured by combining these. As the range contents, the application range information of these discount conditions is stored. The contents of the range are recorded in the CSV format in the format of “tag information: application range information”. The control unit 18 performs a process of generating the discount condition information for notification by replacing the portion surrounded by “” in the content of the format discount condition with the application range information corresponding to the tag inside the “”. For example, the discount condition is “The distance from the entrance interchange to the exit interchange is less than the“ distance range ”. If the entry time to the entrance interchange is “time range” or the exit time from the exit interchange is “time range”, a 50% discount will be applied. And the information “distance range: 100 km, time range: 18:00 to 24:00” is stored. In this case, in the discount condition information for notification, “100 km” in the range content is applied to the “distance range” portion in the text information, and “18:00 to 24:00” in the range content is in the “time range” portion. "The distance from the entrance interchange to the exit interchange is less than 100 km. If the entry time to the entrance interchange is from 18:00 to 24:00 or the exit time from the exit interchange is from 18:00 to 24:00, a 50% discount will be applied. Will be generated.

As information regarding the exit interchange, the name of the exit interchange is stored as information regarding the name of the exit interchange, the name of the connected road as the name of the road to which the exit interchange is connected, and the name of the prefecture as information regarding the direction to which the exit interchange belongs.
The control unit 18 performs discount target interchange notification processing shown in FIG. This process is performed in parallel with other processes in a multitasking manner.

First, it is determined whether or not the vehicle has entered the entrance interchange (S110). That is, the control unit 18 compares the current position information detected by the GPS receiver 8 with the position information of the entrance interchange stored in the discount information table of the database 19 and corresponds to a position within a radius of 50 m from the current position. It is determined whether or not the position of the entrance interchange exists. If it exists, it is determined (detected) that the entrance interchange has been entered. When it is determined that the vehicle has entered the entrance interchange (S110: Y), the process proceeds to S120. On the other hand, when it is not determined that the vehicle has entered the entrance interchange (S110: N), the process proceeds to S110.
In S120, the entrance interchange name corresponding to the position determined to have entered in S110 is stored in the nonvolatile memory of the control unit 18.

  In the subsequent S130, information on the farthest exit interchange where there is a fee discount corresponding to the entrance interchange is extracted and stored. Specifically, the line of the entrance interchange name stored in S120 is extracted from the discount information table of the database 19 and stored in the nonvolatile memory of the control unit 18. That is, the entrance interchange name, location, discount condition content, range content, exit interchange name, connecting road name, and prefecture name are stored in association with each other.

  In subsequent S140, information on the extracted exit interchange is notified. Specifically, information for notification is generated from the entrance interchange name, location, discount condition content, range content, exit interchange name, connecting road name, and prefecture name stored in the nonvolatile memory of the control unit 18 in S130, Output. When there are a plurality of pieces of information regarding the extracted exit interchange, notification information is generated and notified sequentially. The notification information is output by outputting sound from the speaker 20 and displaying text information on the display unit 5.

  The notification information is generated by combining the entrance interchange name, location, discount condition content, range content, exit interchange name, connecting road name, and prefecture name. Specifically, for example, in the discount information table of FIG. 5, when approach to the A-Inter is detected, as described above, as the discount condition information for notification, “the distance from the entrance interchange to the exit interchange is It is less than 100km. If the entry time to the entrance interchange is 18: 00-24: 00 or the exit time from the exit interchange is 18: 00-24: 00, a 50% discount will be applied. Is generated. Of the text information of the discount condition information for notification, information obtained by replacing “entrance interchange” with “entrance interchange name” and “exit interchange” with “exit interchange name” is used as notification information. In other words, the notification information in this case is: “The distance from the A inter to the I inter is 100 km or less. If the entry time to A Inter is from 18:00 to 24:00 or the exit time from I Inter is from 18:00 to 24:00, a 50% discount will be applied. Is generated. Then, the notification information is synthesized by voice and output from the speaker 20. Further, the discount information interchange notification screen as shown in FIG. 7 is drawn from the notification information and displayed on the display unit 5.

  According to such a configuration, when entry into the entrance interchange is detected, information on the farthest exit interchange where there is a fee discount from the entrance interchange is output by voice and screen display. Therefore, the farthest exit interchange where a fee discount exists can be notified at an early stage. You can also be aware of the farthest exit interchange where there is a discount. Therefore, it becomes possible to receive discount application more reliably than before. In particular, this output is preferably performed immediately after the entry is detected as in this embodiment. Such a configuration is suitable for an inexpensive device such as the present embodiment that does not have a route guidance function, but can also be realized as an additional function of a navigation device having a route guidance function, for example.

  In subsequent S150, it is determined whether or not the exit has exited from the exit interchange. That is, the control unit 18 compares the current position information detected by the GPS receiver 8 with the position information of the exit interchange stored in the exit inter information table of the database 19 and corresponds to a position within a radius of 50 m from the current position. It is determined whether or not the position of the exit interchange to be present exists, and if it exists, it is determined (detected) that the exit has exited from the exit interchange. When it is determined that the exit has exited from the exit interchange (S150: Y), the process proceeds to S180. On the other hand, when it is determined that the vehicle has not exited from the exit interchange (S150: N), the process proceeds to S160.

  In S160, it is determined whether or not the stored exit interchange has been approached. That is, when entry to the entrance interchange is detected, it is determined whether the entrance interchange has approached one of the farthest exit interchanges where there is a fee discount. Specifically, the control unit 18 includes the current position information detected by the GPS receiver 8 and the position information of the exit interchange stored in the exit interchange information table of the database 19 corresponding to the exit interchange name stored in S130. Are compared to determine whether or not there is an exit interchange position corresponding to a position within a radius of 2000 m from the current position. If so, it is determined (detected) that the stored exit interchange has been approached. When it is determined that the stored exit interchange has been approached (S160: Y), the process proceeds to S170. On the other hand, when it is determined that the stored exit interchange is not approached (S160: N), the process proceeds to S150.

  In S170, an approach warning is notified. The approach warning performs the same processing as the generation and notification of notification information in S140. For example, as information for notification, “The distance from A Inter to I Inter is 100 km or less. If the entry time to A Inter is from 18:00 to 24:00 or the exit time from I Inter is from 18:00 to 24:00, a 50% discount will be applied. ”Is generated, and the notification information is synthesized by voice and output from the speaker 20 and displayed on the display unit 5 as shown in FIG. Then, the process proceeds to S150.

  On the other hand, in S180, the stored information regarding the entrance interchange name and exit interchange is cleared. That is, the entrance interchange name saved on the non-volatile memory of the control unit 18 in S120, the entrance interchange name, location, discount condition content, range content, exit interchange name saved in the non-volatile memory of the control unit 18 in S130, Clear (erase) the connected road name and prefecture name.

Thus, after the entry to the entrance interchange is detected (S110: Y) and the exit from the toll road to the general road is detected (S150: Y), the farthest exit satisfying the discount condition When approaching the interchange (S160: Y), control is performed to output an approach warning. This process prevents the driver from inadvertently forgetting to leave at the farthest exit interchange that satisfies the discount condition, and after the exit from the toll road to the general road is detected (S150: Y ), The entrance interchange name, location, discount condition contents, range contents, exit interchange name, connecting road name, and prefecture name saved in the nonvolatile memory of the control unit 18 in S130 are cleared (erased) (S180). Even when approaching the exit interchange from the road side, the approach warning will not be notified thereafter. So, for example, if you exit from the exit interchange just before the farthest exit interchange that satisfies the discount condition and then exit the general road, you will pass the general road and approach the farthest exit interchange that satisfies this discount condition. It is possible to prevent the approach warning from being notified. In this embodiment, information on exit interchanges of all toll roads, including exit interchanges that are not applicable to discounts, is stored in the exit inter information table, and exits from toll roads to general roads are based on this information. Is detected (S150: Y), the entrance interchange name, location, discount condition contents, range contents, exit interchange name, connecting road name, and prefecture name saved in the non-volatile memory of the control unit 18 in S130 are cleared (erased). (S180). For example, when the exit interchange stored in the nonvolatile memory of the control unit 18 in S130 is passed, the entrance interchange stored in the nonvolatile memory of the control unit 18 in S130. Name, location, discount condition content, range content, exit interchange name, connecting road , It may be the prefecture name to be cleared (erased). This passage is, for example, when the current position enters the position within 2000 m from the position of the exit interchange stored in the non-volatile memory of the control unit 18 in S130, and then the current position goes out of 2000 m. Various methods, such as determining that it has passed, can be taken.
Further, the following configuration may be provided.

The database 19 stores road network data of toll roads. The road network data of the toll road is data having a graph structure including a node including position information on the toll road and a link indicating a connection state between the nodes, and is used in a general navigation apparatus.
And the control part 18 performs the process of S10 to S40 shown in FIG. This process is multitasked with other processes.

  In S10, it is determined whether or not the vehicle is on a toll road. That is, the current position information detected by the GPS receiver 8 is compared with the road network data in the database 19, and when the current position is on the link, it is determined that the vehicle is on a toll road. Note that whether or not the current position is on the road link may be determined by performing a so-called map matching process or the like. When it is determined that the current position is not on the toll road (S10: N), the process proceeds to S20. On the other hand, when it is determined that the current position is on the toll road (S10: Y), the process proceeds to S10.

  In S20, it is determined whether or not the entrance interchange has been approached. That is, the control unit 18 compares the current position information detected by the GPS receiver 8 with the position information of the entrance interchange stored in the discount information table of the database 19 and corresponds to a position within a radius of 1000 m from the current position. It is determined whether or not the position of the entrance interchange to be present exists, and if it exists, it is determined (detected) that the entrance interchange has been approached. When it determines with having approached the entrance interchange (S20: Y), it transfers to S30. On the other hand, when it determines with not approaching an entrance interchange (S20: N), it transfers to S10.

  In S30, information on the farthest exit interchange where there is a fee discount corresponding to the entrance interchange corresponding to the position determined to have approached in S20 is extracted and stored. Specifically, a row at the position of the entrance interchange determined to have approached in S 20 is extracted from the discount information table of the database 19 and stored in the nonvolatile memory of the control unit 18. That is, the entrance interchange name, location, discount condition content, range content, exit interchange name, connecting road name, and prefecture name are stored in association with each other.

  In S40, information about the extracted exit interchange is notified. Specifically, information for notification is generated from the entrance interchange name, location, discount condition content, range content, exit interchange name, connecting road name, and prefecture name saved in the nonvolatile memory of the control unit 18 in S30. Output. The notification information is output by outputting sound from the speaker 20 and displaying text information on the display unit 5.

  The notification information is generated by combining the entrance interchange name, location, discount condition content, range content, exit interchange name, connecting road name, and prefecture name. Specifically, for example, in the discount information table of FIG. 5, when approach to the A-Inter is detected, as described above, as the discount condition information for notification, “the distance from the entrance interchange to the exit interchange is It is less than 100km. If the entry time to the entrance interchange is from 18:00 to 24:00 or the exit time from the exit interchange is from 18:00 to 24:00, a 50% discount will be applied. Is generated. Then, add “There is an entrance interchange within 1 km” before the text information of the discount condition information for notification, replace “entrance interchange” with “entrance interchange name”, and replace “exit interchange” with “exit interchange”. The information replaced with “name” is used as notification information. In other words, as information for notification in this case, “There is A Inter within 1km. The distance from A Inter to I Inter is less than 100 km. If the entry time to A Inter is from 18:00 to 24:00, or the exit time from I Inter is from 18:00 to 24:00, a 50% discount will be applied. Is generated. Then, the notification information is synthesized by voice and output from the speaker 20. In addition, a drawing process of a notification screen for displaying the character string of the notification information is performed and displayed on the display unit 5.

  In this way, a step (S10) for determining whether the vehicle is traveling on a toll road or a general road and a step (S20) for detecting approach to the entrance interchange are provided, and the vehicle is traveling on a general road. Is determined (S10: N), and the approach to the entrance interchange is detected (S20: Y), information on the farthest exit interchange where there is a fee discount is output from the entrance interchange (S40). It is preferable that the control be performed.

  According to such a configuration, even when driving on a general road that is not a toll road, when approaching the entrance interchange, information on the farthest exit interchange where there is a fee discount is output from the entrance interchange. The Therefore, even when traveling on a general road, it is possible to recognize the farthest exit interchange where there is a fee discount from the entrance interchange in the vicinity. Therefore, for example, even those who do not normally use toll roads can be aware of the farthest exit interchange where there is a toll road price discount.

  The notification mode of information related to the name of the exit interchange is not limited to that described above, and various modes can be adopted. For example, it is good to set it as the structure which outputs the information regarding the name of an exit interchange with the information regarding the name of the road to which the said exit interchange connects, and the information to which the said exit interchange belongs. Also, along with the road name, it may be reported whether the exit interchange belongs to the upper or lower line, or it may be reported which direction the exit interchange is from the entrance interchange. Good. For example, “exit interchange” is replaced with “exit interchange name” as a process for generating notification information at the time of notification in S140. This process is performed by connecting “exit interchange” with “prefecture name”. The processing may be replaced with “exit interchange name” in “road name”. In this case, in the case of the above-mentioned example, as the information for notification, “The distance from A Inter to I Inter on Tomei Expressway in Shizuoka Prefecture is 100 km or less. If the entry time to A Inter is from 18:00 to 24:00 or the exit time from I Inter on the Tomei Expressway in Shizuoka Prefecture is from 18:00 to 24:00, a 50% discount will be applied. ”Is generated, and the information for notification is synthesized by voice and output from the speaker 20 and displayed on the display unit 5.

  According to such a configuration, the information about the name of the exit interchange is output together with the information about the name of the road to which the exit interchange is connected. It becomes difficult to occur. For example, the driver can easily determine whether the information is about the interchange on the road on which he / she travels by hearing the name of the road. Further, since information regarding the name of the exit interchange is output for each piece of information regarding the direction to which the exit interchange belongs, for example, it is possible to solve the problem that the name of the exit interchange is unknown by hearing the name of the exit interchange. As the information regarding the direction, not the prefecture name but the area name indicating the region may be used.

  In addition, the information regarding the name of the exit interchange may be output for each information regarding the direction to which the exit interchange belongs, or may be output for each information regarding the discount condition of the exit interchange. For example, in S130, information on the farthest exit interchange where there is a charge discount corresponding to the entrance interchange is extracted and stored, and the row of the entrance interchange name stored in S120 is extracted from the discount information table of the database 19 in the saving process. In this case, after sorting by information about the direction to which the exit interchange belongs (prefecture name in the example of FIG. 5), sort by information on discount conditions of the exit interchange (discount condition contents in the example of FIG. 5). The extracted row information, that is, the entrance interchange name, position, discount condition content, range content, exit interchange name, connecting road name, and prefecture name are associated with each other and stored in the nonvolatile memory of the control unit 18. In subsequent S140, information regarding the extracted exit interchange is notified. Specifically, notification information at the time of entry is performed from the entrance interchange name, location, discount condition content, range content, exit interchange name, connecting road name, and prefecture name saved in the non-volatile memory of the control unit 18 in S130. It is preferable that the notification information is sequentially generated and output every time.

  In this way, the information about the name of the exit interchange is output for each piece of information about the discount condition of the exit interchange, so it is possible to easily grasp under which discount conditions the exit interchange is discounted. According to such a configuration, the driver can easily determine which discount condition should be used, and at which interchange to get off. Further, among the same information regarding the discount conditions for the exit interchange, the same information regarding the direction to which the same exit interchange belongs (prefecture name in the example of FIG. 5) is continuously notified. Therefore, it is possible to easily know the exit interchange to be discounted at an early stage. In addition, it is possible to be aware of the exit interchange to be discounted, and it is possible to receive discount application more reliably than before.

  Note that, for example, in S130, sorting may be performed only on information relating to the direction to which the exit interchange belongs (prefecture name in the example of FIG. 5). If it does in this way, it will be alert | reported for every direction and it can alert | report easily.

  Furthermore, when an entry to the entrance interchange is detected (S110: Y), information on the exit interchange that currently does not satisfy the discount condition among the information on the farthest exit interchange for which there is a fee discount from the entrance interchange. It is better to have a configuration that does not output. For example, in the process of S130, in the process of extracting the row of the entrance interchange name saved in S120 from the discount information table of the database 19 and storing it in the nonvolatile memory of the control unit 18, the discount condition contents include “entry time”. ”Is included, only those whose current time acquired from the GPS receiver 8 is within the time range indicated by“ time range ”of“ range ”in the discount information table are stored. Do not save anything in Whether or not the discount condition is currently satisfied can be determined based on various types of information, not limited to the time range. For example, it may be performed based on information obtained by receiving radio waves from the outside, information obtained from a vehicle, information obtained from a sensor provided in the electronic device, or the like.

  In this way, when entering the entrance interchange, information related to the exit interchange that satisfies the discount condition is notified, and information related to the exit interchange that does not satisfy the discount condition is not notified. Therefore, only the farthest exit interchange that satisfies the discount condition can be notified to the driver or the like, and the driver can be made aware of it. Therefore, it is possible to provide an easy-to-use electronic device that can be more reliably discounted than before.

  The discount condition may be incorporated during the processing, for example. For example, discount conditions may be stored in the program, and information regarding each exit interchange and information regarding fees from each entrance interchange to each exit interchange may be stored in a recording medium or the like.

  Further, in the above-described embodiment, the detection of entry to the expressway is the position information (latitude and longitude) of the point on the entrance road of the entrance interchange, and this latitude and longitude entered the 30m toll road from the toll gate. However, the present invention is not limited to this, and may be a position on a route entering the main road of the highway or a position on the main road of the highway.

  Further, a setting screen for setting a discount condition to be output among the discount conditions is displayed on the display unit 5, and a function for detecting a button operation of the remote controller 17 to set a discount condition for the output target is provided. A configuration corresponding to the discount condition to be output set on the setting screen may be output. For example, when pressing of the setting button of the remote controller 17 is detected, as shown in FIG. 9, whether the discount condition related to “distance”, the discount condition related to “time”, and the discount condition related to “route” are to be output. When an output target discount condition setting screen for setting whether or not is displayed and an operation of the upper button or the lower button of the cross button of the remote controller 17 is detected, the focus frame 51 is related to a discount condition related to “distance” and “time”. A display for moving in a corresponding direction between the discount condition and the discount condition regarding the “route” is performed. When the pressing of the selection button on the remote controller 17 is detected, the check state of the check box on the left side of the item surrounded by the focus frame 51 is reversed. A state with a check is a setting to be output, and a state without a check is a setting not to be an output target. The check state when the enter button on the remote controller 17 is pressed is stored in the database 19 as a setting. Then, in the extraction process of S130 described above, from the discount information table of the database 19, the line having the discount condition set as the output target stored in the database 19 is extracted and controlled from the entrance interchange name stored in S120. The data is stored on the nonvolatile memory of the unit 18. According to such a configuration, useless notification can be suppressed. For example, when only the discount condition related to “route” is to be output as shown in FIG. 9 and the example of the discount information table in FIG. No notification is made, and the content corresponding to the fifth line is notified.

  The discount conditions are not limited to these. For example, in the case of discount conditions that apply only to ordinary vehicles, it is not necessary to notify the driver of a large vehicle of information on an exit interchange to which the discount conditions are applied. Therefore, for example, information on each exit interchange and information on charges from each entrance interchange to each exit interchange are stored separately for ordinary vehicles and large vehicles, and based on user operations, etc. Either of them may be set. And it is good for the control part 18 to output only about what satisfy | fills this set discount condition.

  Further, when the farthest exit interchange that satisfies the discount condition from the entrance interchange stored in S130 changes, the control unit 18 may perform control to output information regarding the exit interchange after the change. For example, it has a function of communicating with the mobile phone 12 via the infrared communication device 7 at regular intervals, and acquiring and updating the contents of the discount information table in the database 19 from a server accessible from the mobile phone 12. In this case, it is preferable to execute the processing after S120 again after the update. At this time, the content updated in S130 and the content stored in the nonvolatile memory are compared, and if the two are different, the updated content may be notified. For example, after entering from A Interchange, if the information of “Exit Interchange Name” in the discount information table of Database 19 is updated to “P Interchange”, “There has been a change to the exit interchange that satisfies the discount conditions. The distance from A Inter to P Inter is less than 100 km. If the entry time to A Inter is from 18:00 to 24:00 or the exit time from P Inter is from 18:00 to 24:00, a 50% discount will be applied. "

  According to such a configuration, when the exit interchange satisfying the discount condition is changed from the previously notified one, information on the exit interchange satisfying the current discount condition is output again. Therefore, it is possible to ensure that a discount is applied.

  Furthermore, the detection of the entry in S110 can take various forms. For example, a point on the route to the main line as position information of the entrance interchange of the database 19 and before branching in the upper or lower direction of the main line and a point after branching in the direction of the up line of the main line And the line regarding 3 points | pieces with the point after a branch in the direction of the down line of the said main line is each memorize | stored. The row at the point before the branch is provided with both information relating to the discounted exit interchange in the up line direction and information relating to the discounted exit interchange in the down line direction. Then, the first detection is performed at a point before branching, and the second detection is performed at a point after branching in either the upper or lower direction of the main line. And control part 18 performs control which outputs information for information by the 2nd detection after control which outputs information for information by the 1st detection. In this way, before the branch of the upper and lower lines of the toll road, if you go in the up direction, to which interchange the discount is applied, if you go in the down direction, to which interchange It is possible to know whether the discount is applied, and after the branch, it is possible to know up to which interchange the discount is applied in the direction of driving. Therefore, it is possible to recognize the exit interchange to be discounted.
