(Embodiment)
(Functional configuration of electronic equipment)
FIG. 1 is a block diagram showing a functional configuration of an electronic apparatus according to an embodiment of the present invention. As illustrated in FIG. 1, the electronic device 100 according to the embodiment of the present invention includes a detection unit 101, a determination unit 102, a recording unit 103, an acquisition unit 104, a determination unit 105, and an output unit 106. It is equipped with.

  The detection unit 101 detects ON / OFF of an accessory power source (not shown). The accessory power supply is turned on / off by, for example, turning on / off the vehicle engine by the user. For example, the user turns on the accessory power source when moving the vehicle toward a destination point or a resting point, and turns off the accessory power source when leaving the vehicle at the destination point or the resting point. The accessory power source is electrically connected to, for example, a battery provided in the vehicle, and supplies electricity to various electrical components mounted on the vehicle by a user operation. Since the detection unit 101 is a known technique and will not be described in detail, it can be realized by using various electric measurement sensors, for example.

  When the detection unit 101 detects that the accessory power supply is turned off, the determination unit 102 determines whether a recording medium is attached to the ETC on-vehicle device. The determination unit 102 can be realized, for example, by detecting the presence / absence of a recording medium with a sensor or the like provided in an IC card slot provided in the ETC on-vehicle device. Since the ETC on-board unit and the internal structure of the IC card slot are well-known techniques, description thereof is omitted here.

  The recording unit 103 records map information. The map information is information including background data representing a point object (feature) such as a building, a river, a surface of a point, road shape data representing a shape of a road, and point attribute information. The attribute information is, for example, information indicating the type and characteristics of the facility or road at the point. Further, the attribute information may include information indicating that the point is registered by the user, information on a movement history generated from the movement history of the user, and the like. The information related to the movement history is, for example, information indicating the history of the points where the vehicle has moved and the staying time at each point that can be calculated from the number of hours from when the accessory power supply is turned off to when the vehicle is turned on again. The recording unit 103 can be realized, for example, by using a recording medium such as a DVD or a hard disk on which map information is recorded and a reading device for the recording medium.

  When the determination unit 102 determines that the recording medium is mounted, the acquisition unit 104 acquires attribute information of a point where the accessory power supply is detected to be off by the detection unit 101. The acquisition unit 104 can be realized, for example, by using GPS (Global Positioning System) and map information together.

  The determination unit 105 determines whether or not the attribute information acquired by the acquisition unit 104 matches a specific condition regarding the use time of the facility existing at the point. Whether or not a specific condition relating to the usage time is met is determined based on, for example, attribute information of a facility existing at the point. Specifically, it is determined whether or not the location attribute information is information representing a predetermined type of facility, whether or not the location is registered by the user, and the like.

  The output unit 106 does not output a sound when the determining unit 105 determines that the attribute information matches a specific condition regarding the usage time of the facility existing at the point, and outputs a sound when it is determined that the attribute information does not match. Output. Further, without providing the electronic device 100 with a separate determination unit 105, the output unit 106 outputs a voice message when the attribute information acquired by the acquisition unit 104 matches a specific condition regarding the use time of the facility existing at the point. May not be output and audio may be output if they do not match. The output unit 106 can be realized by using a speaker or the like.

(Processing procedure of electronic device 100)
Next, a processing procedure of the electronic device 100 according to the embodiment of the present invention will be described. FIG. 2 is a flowchart illustrating a processing procedure of the electronic device 100 according to the embodiment of the present invention. The flowchart shown in FIG. 2 is performed, for example, when the user turns off the accessory power supply of the vehicle, for example, when the user turns off the engine of the vehicle. In the flowchart shown in FIG. 2, first, the electronic device 100 waits until it detects that the accessory power supply is turned off (step S201: No loop).

  If it is determined in step S201 that the accessory power supply has been turned off (step S201: Yes), it is determined whether a recording medium is mounted on the ETC on-vehicle device (step S202). If it is determined in step S202 that the recording medium is mounted on the ETC on-vehicle device (step S202: Yes), the process proceeds to step S203. If it is determined that the recording medium is not loaded (step S202: No), the series of processes is terminated as it is.

  If it is determined in step S202 that the recording medium is attached to the ETC on-vehicle device, the electronic device 100 then acquires attribute information of the point where the accessory power supply is detected to be off (step S203). In step S203, after acquiring the attribute information of the point where the accessory power supply is detected to be off, it is determined whether or not the acquired attribute information meets a specific condition regarding the use time of the facility existing at the point (step S204). .

  If it is determined in step S204 that the specific condition is met (step S204: Yes), a series of processing is terminated without outputting the sound (step S205). If it is determined that the specific condition is not met (step S204: No), a sound is output (step S206), and the series of processes is terminated.

  As described above, according to the electronic device 100 of the embodiment of the present invention, it is possible to selectively output sound at a point where the accessory power supply is detected to be off. More specifically, voice output can be selectively performed depending on whether or not the attribute information of the point where the accessory power supply is turned off meets a specific condition regarding the usage time. As a result, it is possible to prevent the sound from being output when the specific condition relating to the usage time is met. This eliminates inadvertent voice alerts at points that meet specific conditions related to usage time, and prevents information that the vehicle equipped with an ETC card is unattended from being guided to the surroundings. , Can improve crime prevention.

  Further, according to the electronic device 100 of the embodiment of the present invention, the audio output is selected depending on whether or not the attribute information of the point where the accessory power supply is detected is information indicating a point where the purpose of use can be limited. Can be done manually. Thereby, for example, when the point where the accessory power supply is detected to be off is a point where the manufacturing side of the electronic device 100 determines that the usage time is short, it is possible to prevent the sound from being output. This eliminates inadvertent voice output at a point where the manufacturing side of the electronic device 100 determines that the usage time is short, and informs the surroundings that the vehicle equipped with the ETC card becomes unattended. The crime prevention property can be improved.

  Further, according to electronic device 100 of the embodiment of the present invention, the attribute information of the point where the accessory power supply is detected is information indicating a resting facility that can be used in combination with a convenience store, a gas station, and a toll road. In this case, it is possible not to output sound. This eliminates inadvertent audio output at rest facilities that can be used in conjunction with convenience stores, gas stations, and toll roads, and informs the surroundings that vehicles equipped with ETC cards will be unattended. The crime prevention property can be improved.

  In addition, for example, a registration unit may be further provided in the electronic device 100 to determine the presence or absence of audio output based on user registration. Thereby, for example, it is possible to flexibly improve crime prevention according to the various needs of users, such as not outputting audio in stores where convenience stores are limited.

  In addition, for example, the electronic device 100 is further provided with a timing unit, which measures the time from when the accessory power supply is turned off to when it is turned on again, at the point where the measured time is recorded as attribute information. When the time is within the reference time, it may be configured not to output sound. That is, in this case, the electronic device 100 measures and records the time from when the accessory power supply at each point is turned off to when it is turned on again as information on the movement history of the user. And when the information regarding the movement history of the point where the accessory power supply is detected is within a predetermined reference time, the voice is not output at the point. Thereby, for example, for a user who stays in a convenience store for a long time on a daily basis, the crime prevention property can be improved according to the living situation of the user, such as outputting a voice also at the convenience store.

  Next, examples of the electronic device 100 according to the above-described embodiment will be described.

(Output of warning message of ETC system 300)
The ETC system 300 is set such that, for example, a warning message is not output at a predetermined point determined by the manufacturing side of the ETC system 300 when the user stays only for a short time, such as a convenience store or a gas station. That is, whether or not a warning message is output at the point is determined according to the type of the point recorded in advance in the map information by the manufacturing side of the ETC system 300. Further, the ETC system 300 may register a point where the user stops the warning in the exclusion list in advance, thereby determining whether or not a warning message is output at the point.

(Exclusion list configuration)
Here, the exclusion list of the embodiment will be described. As described above, in the ETC system 300, the user registers the point where he / she wants to stop outputting the warning message in the exclusion list, thereby stopping the output of the warning message at the point. The exclusion list stores information on an arbitrary point (hereinafter referred to as “non-warning point”) where output of a warning message indicating that the ETC card is still attached to the ETC card reader 405 is desired to be stopped.

  The non-warning point is an arbitrary point designated by the operation of the input device 511 by the user, for example, a point where a convenience store or a gas station exists. The information related to the non-warning point may be a name recorded in the map information of the non-warning point, longitude / latitude information representing the non-warning point, or coordinates on the map. It may be information representing.

  FIG. 6 is an explanatory diagram showing a schematic configuration of the exclusion list. As shown in FIG. 6, the exclusion list 600 stores information 601 regarding non-warning points.

Here, the information 610 related to the name and coordinates can specifically specify a point on the map such as “Name: Convenience store XX Kasumigaseki” or “Coordinates: (□□, ■■)”. Information. Points registered in the exclusion list 600 may be registered by the user operating the input device 511 and inputting the name of the point, or may be registered by directly inputting the coordinates. Good.

  Specifically, the attribute information 620 is, for example, information indicating the location area of a location such as “Tokyo” or “Chiyoda-ku” recorded in the map information, “convenience store”, “gas station”, etc. Information indicating the type of point. Further, the attribute information 620 is not limited to these, and any information may be used as long as the information represents the feature of the point. In addition, tag information is added to each item such as the information indicating the location area of the attribute information 620 and the information indicating the type of the point, and each item is narrowed down to the user, and a non-warning point is registered. It is good also as the structure made easy.

  The attribute information 620 may be added with information aggregated from information related to the user's movement history. Specifically, for example, when the engine of the vehicle is turned off, the location of the vehicle when the engine is turned off and the time when the engine is turned off are recorded, and the time when the engine is turned on again From this, the number of hours during which the engine is off may be calculated, and the calculated number of hours may be aggregated for each point to obtain attribute information 720 for each point. Thereby, for example, when the user selects “automatic setting mode” in the setting of the exclusion list 600, the average number of hours in which the engine is turned off is calculated from the total number of hours in which the engine has been turned off for each point. Then, a point such as within 15 minutes can be registered in the exclusion list 600.

  Specifically, the warning information 630 is information relating to a non-warning condition at a non-warning point registered in the exclusion list 600, for example. The non-warning condition is a condition when no warning is given, such as a condition specified by an operation of the input device 511 by the user.

  More specifically, the non-warning condition can be set by combining information about the name and coordinates 610 with time information obtained from a clock function or the like installed in the navigation device 302. Thus, for example, it is possible to set a non-warning only when “convenience store XX 霞 Sekiga Seki” is used in the daytime. Specifically, for example, in the “convenience store XX Kasumigaseki store”, a warning is not given in the time zone from 8:00 to 18:00, but a warning is given in other time zones.

(Procedure for registering non-warning points in the exclusion list 600)
Next, a procedure when the user registers a non-warning point in the exclusion list 600 will be described. Here, for example, a procedure when the user registers “Convenience store XX 霞 ga Seki store” in the exclusion list 600 as a non-warning point will be described as an example.

  First, the user sets the setting of the navigation device 302 to the “exclusion list registration mode”. As a result, the navigation device 302 switches from “route guidance mode” for guiding route information to the destination point to “exclusion list registration mode” for registering non-warning points in the exclusion list 600. Therefore, the navigation device 302 displays, for example, “What type of point you want to register?” On the display 513.

  Next, the user inputs “convenience store”. Thereby, a list of convenience stores is displayed on the display 513. The convenience store list is, for example, a list for each type of convenience store such as “convenience store XX”, “convenience store □□”, “△△ convenience store”.

  Next, the user selects “Convenience store XX”. Thereby, the list of prefectures is displayed on the display 513. The list of prefectures is a list of prefectures such as “Tokyo”, “Saitama”, and “Kanagawa”. Next, the user selects “Tokyo”. As a result, a list of municipalities in Tokyo is displayed on the display 513. The list of municipalities is a list of municipalities in Tokyo such as “Chiyoda Ward”, “Minato Ward”, “Chuo Ward”, and the like. Therefore, the user selects “Chiyoda-ku”. Thereby, a list of convenience stores XX in Chiyoda-ku is displayed on the display 513.

  Next, the user selects Kasumigaseki from the store list of convenience stores XX in Chiyoda-ku. As a result, “Convenience store XX 霞 may register Seki store in the exclusion list?” Is displayed on the display 513 to confirm the registration to the user. By selecting “Yes” there, the user can register “Convenience store XX Kasumigaseki” in the exclusion list 600.

  Also, for example, if the user is currently parked at “Convenience store XX 霞 Seki store”, create a request button such as “Register current location in the exclusion list” and press the request button. “Convenience store XX Kasumigaseki store” may be easily registered in the exclusion list 600.

  Further, a plurality of points may be registered in the exclusion list 600 at a time. For example, when the user registers “Convenience Store XX Kasumigaseki” in the exclusion list 600, the display 513 displays “Do you want to register all convenience stores in the exclusion list?” "Or" No "may be selected. At this time, when the user selects “Yes”, all the convenience stores are registered in the exclusion list 600 at a time.

  The exclusion list 600 can be set according to the needs of the user by setting a plurality of the above-mentioned warning conditions at the same time. Specifically, for example, it is possible to set so as not to issue a warning during the daytime in all convenience stores.

(Processing procedure when registering exclusion list 600)
FIG. 7 is a flowchart showing a processing procedure when the exclusion list 600 is registered. The flowchart shown in FIG. 7 is appropriately performed at any timing of the user, for example. In the flowchart shown in FIG. 7, first, the ETC system 300 waits until a request for exclusion list registration is received from the user (step S <b> 701: No loop).

  If there is a request for registration of the exclusion list from the user (step S701: Yes), the process waits until the name or coordinates of the point to be registered in the exclusion list 600 is received (step S702: No loop). If the name or coordinate of the location to register is received (step S702: Yes), a new exclusion list 600 including the name or coordinate of the location to be registered is generated (step S703). Thereafter, a new exclusion list 600 is recorded (step S704), and a series of processing is terminated.

  In addition, when the user selects, for example, crime prevention setting ON / OFF, and the user selects crime prevention setting ON, the ETC system 300 is manufactured if the stay time of the user such as a convenience store or a gas station is short. When the accessory power supply is detected with the ETC card attached to the ETC card reader 405 at the point determined by the side or registered in the exclusion list 600, the warning message output is stopped and the crime prevention setting OFF is selected. In some cases, a warning message may be output when it is detected that the accessory power supply has been turned off while the ETC card is attached to the ETC card reader 405 at any point.

  Next, a processing procedure of the ETC system 300 according to the embodiment will be described. The processing procedure (No. 1) of the ETC system 300 shown below is a processing procedure when determining whether or not to output a warning message according to the type of spot recorded in advance in the map information by the manufacturing side of the ETC system 300. Yes, the processing procedure (part 2) of the ETC system 300 is a processing procedure for determining whether or not to output a warning message based on the exclusion list 600.

(Processing procedure of ETC system 300 (part 1))
FIG. 8 is a flowchart illustrating the processing procedure (part 1) of the ETC system 300 according to the embodiment. The flowchart shown in FIG. 8 is performed, for example, when the ETC system 300 detects that the accessory power supply is turned off, for example, when the user turns off the engine of the vehicle. In the flowchart shown in FIG. 8, first, the ETC system 300 waits until it detects that the accessory power supply is turned off (step S801: No loop).

  If it is detected that the accessory power supply is turned off (step S801: Yes), it is determined whether an ETC card is attached to the ETC card reader 405 (step S802). If it is determined that an ETC card is attached to the ETC card reader 405 (step S802: Yes), the process proceeds to step S803. If it is determined that the ETC card is not attached to the ETC card reader 405 (step S802: No), the series of processing ends.

  If it is determined in step S802 that an ETC card is attached to the ETC card reader 405, the ETC system 300 next determines whether or not the setting is crime prevention setting ON (step S803). If it is determined that the crime prevention setting is ON (step S803: Yes), the process proceeds to step S804. If it is determined that the crime prevention setting is not ON (step S803: No), a warning message is output (step S808), and the series of processing ends. If it is determined in step S803 that the crime prevention setting is ON, then the ETC system 300 acquires information on the current location (step S804).

  Information on the current location includes information indicating the position of the current location of the vehicle, attribute information at the current location recorded in the map information, and the like. After acquiring information related to the current location, information related to the departure time is acquired from information related to the current location (step S805). The information related to the departure time is information set according to the type at each point recorded in advance in the map information by the manufacturing side of the ETC system 300, for example. Specifically, for example, the manufacturing side of the ETC system 300 estimates that the stay time is shorter than a predetermined time with respect to a convenience store, adds information indicating that the stay time is shorter than the predetermined time, and other information. Information indicating that the stay time is longer than the predetermined time is added to the point where the stay time is estimated to be longer than the predetermined time.

  In step S805, after acquiring information related to the departure time, it is determined whether or not to stop outputting the warning message from the information related to the departure time (step S806). Specifically, it is determined that the output of the warning message is stopped when the information about the current location in the map information is added to the information indicating the location where the stay time is shorter than the predetermined time, and the stay time is longer than the predetermined time. Is added, it is determined that a warning message is output.

  If it is determined from the information regarding the departure time that the output of the warning message is to be stopped (step S806: Yes), the output of the warning message is stopped (step S807), and the series of processing ends. If it is determined not to stop the output of the warning message from the information related to the departure time (step S806: No), the warning message is output (step S808), and then the series of processes is terminated.

(Processing procedure of ETC system 300 (part 2))
FIG. 9 is a flowchart illustrating the processing procedure (part 2) of the ETC system 300 according to the embodiment. The processing procedure (part 2) of the ETC system 300 according to the embodiment is a processing procedure when the output of the voice message is stopped based on the exclusion list 600 described above. The flowchart shown in FIG. 9 is performed, for example, when the ETC system 300 detects that the accessory power supply is turned off, for example, when the user turns off the engine of the vehicle. In the flowchart shown in FIG. 9, first, the ETC system 300 waits until it detects that the accessory power supply is turned off (step S901: No loop).

  If it is detected that the accessory power supply is turned off (step S901: Yes), it is determined whether an ETC card is attached to the ETC card reader 405 (step S902). If it is determined that an ETC card is attached to the ETC card reader 405 (step S902: Yes), the process proceeds to step S903. If it is determined that the ETC card is not attached to the ETC card reader 405 (step S902: No), the series of processing ends.

  If it is determined in step S902 that an ETC card is attached to the ETC card reader 405, the ETC system 300 next determines whether or not the setting is a crime prevention setting ON (step S903). If it is determined that the crime prevention setting is ON (step S903: Yes), the process proceeds to step S904. If it is determined that the crime prevention setting is not ON (step S903: No), a warning message is output (step S908), and the series of processing ends. If it is determined in step S903 that the crime prevention setting is ON, then the ETC system 300 acquires information on the current location (step S904). After acquiring information about the current location, the exclusion list 600 is referred to (step S905).

  After referring to the exclusion list 600, it is determined whether or not the current location is a location registered in the exclusion list 600 (step S906). If it is determined that the current location is a location registered in the exclusion list 600 (step S906: Yes), the output of the warning message is stopped (step S907), and the series of processing ends. If it is determined that the current location is not registered in the exclusion list 600 (step S906: No), a warning message is output (step S908), and then the series of processes is terminated.

  As described above, according to the ETC system 300 of the embodiment, the output of the warning message at the point where the accessory power supply is detected to be off can be stopped based on the information regarding the leaving time. As a result, when the departure time is shorter than the predetermined time, at the point where the manufacturing side of the ETC system 300 recorded in the map information, the output of the warning message is stopped and the vehicle equipped with the ETC card becomes unmanned at the point. Can be prevented from being guided to the surroundings, and crime prevention can be improved.

  Further, according to the ETC system 300 of the embodiment, when the attribute information of the point where the accessory power supply is detected to be off is information indicating a resting facility that can be used in combination with a convenience store, a gas station, and a toll road. The warning message can be prevented from being output. This eliminates inadvertent warnings at rest facilities that can be used in conjunction with convenience stores, gas stations, and toll roads, and informs the surroundings that vehicles equipped with ETC cards will be unattended. The crime prevention property can be improved.

  Further, according to the ETC system 300 of the embodiment, by registering a point where the user does not wish to output a warning message as a non-warning point in the exclusion list 600, the output of the warning message at the point can be stopped. . This stops the output of the warning message at any point according to the user's wish, and prevents the information that the vehicle equipped with the ETC card is unattended from being guided to the surroundings, Crime prevention can be improved.

  Further, according to the ETC system 300 of the embodiment, it is possible to determine whether or not a warning message is output based on information related to the movement history of the user. Thereby, for example, for a user who stays in a convenience store for a long time on a daily basis, the crime prevention property can be improved according to the living situation of the user, such as outputting a voice also at the convenience store.

  The voice output method described in this embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read from the recording medium by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.
