  In addition, for example, the scene information acquisition unit 13 determines whether or not the acquired current position information matches the position information included in the various information, and acquires the various information including the position information when they match. To do. The “determining whether or not they match” includes determining whether or not they are included in the range indicated by the position information. For example, when acquiring road information, the scene information acquisition unit 13 determines whether the acquired current position information matches the road position information included in the map road information. And when it corresponds, the scene information acquisition part 13 acquires the said map road information as road information which is scene information. For example, when acquiring area information, the scene information acquisition unit 13 determines whether the acquired current position information is included in a range indicated by the area position information included in the map area information. If it is included, the scene information acquisition unit 13 acquires the map area information as area information that is scene information. For example, when acquiring terrain information, the scene information acquisition unit 13 determines whether the acquired current position information matches the terrain position information included in the map terrain information, or included in the range indicated by the terrain position information. To determine whether or not If they match or are included, the scene information acquisition unit 13 acquires the map terrain information as terrain information that is scene information.

  In addition, when acquiring position-related information, the scene information acquisition unit 13 usually performs various position-related information from a satellite navigation system (such as a GPS receiver) or a device that receives position information from a base station for mobile communication. Get information. In this case, the scene information acquisition unit 13 may have these devices or may be realized by these devices.

  For example, when acquiring state-related information, the scene information acquisition unit 13 normally determines an ignition sensor that detects whether the engine is on or off, a speedometer that measures the speed of the moving body, and the fuel remaining amount of the moving body. Various state-related information is acquired from a device such as a fuel fuel gauge to be measured. In this case, the scene information acquisition unit 13 may have these devices or may be realized by these devices.

Further, the scene information acquisition unit 13 usually has a correspondence table of time conditions indicating time conditions and time subdivisions, acquires time subdivisions corresponding to time conditions that the acquired time information matches, Get time zone information. In this case, the scene information acquisition unit 13 may have a clock or may be realized by a clock.

  For example, when acquiring weather-related information, the scene information acquisition unit 13 acquires weather-related information such as weather information from a device that normally receives weather information, forecast weather information, precipitation probability information, and the like. For example, when the weather information or the like is stored in a predetermined storage area or an arbitrary storage area, the scene information acquisition unit 13 may acquire the weather information or the like from the storage area. The scene information acquisition unit 13 usually acquires weather-related information such as rainfall information from a rain gauge that measures rainfall, a thermometer that measures temperature, and a hygrometer that measures humidity. In this case, the scene information acquisition unit 13 may have these devices or may be realized by these devices.

  The scene information acquisition unit 13 normally continues to acquire scene information from immediately after the vehicle-mounted device 1 is turned on until the power is turned off. The acquisition timing is usually regular such as every second, every 10 minutes, or every hour, but may be irregular. For example, the scene information acquisition unit 13 may acquire scene information every time a region such as a prefecture or a municipality changes. In addition, since the method, procedure, etc. which detect that the area changed are well-known, detailed description is abbreviate | omitted.

  Moreover, the acquisition timing of scene information may be predetermined for each type of scene information. For example, information that changes from moment to moment as the vehicle travels and time elapses, such as position information, speed information, and time information, among scene information may be determined to be acquired periodically. In addition, for example, information that differs for each predetermined region (region, etc.), such as region name information, forecast weather information, and precipitation probability information, among scene information, every time the moving object passes the boundary of the region. It may be decided to get to.

  The scene information acquisition unit 13 may accumulate the acquired scene information in the series of travel information storage unit 12. At this time, the scene information acquisition unit 13 may accumulate the scene information as a series of travel information.

  The processing procedure of the scene information acquisition unit 13 is usually realized by software, and the software is recorded on a recording medium such as a ROM.

  The music data acquisition unit 14 acquires music data from the music data storage unit 11 using a series of travel information stored in the series travel information storage unit 12 during a series of travels. In addition, the music data acquisition unit 14 does not use the used series of travel information after the series of runs.

For example, the music data acquisition unit 14 acquires the music data according to the route distance information so that the reproduction time of the music data to be reproduced when arriving near the destination is increased.

  Further, for example, the music data acquisition unit 14 acquires the number-of-plays information stored in the series-run information storage unit 12 during a series of runs, and the music data from the music data storage unit 11 according to the number of times of playback information. Get the data. For example, the music data acquisition unit 14 acquires the music data so that the music data acquisition unit 14 satisfies at least a predetermined condition.

  For example, the music data acquisition unit 14 may give information indicating that it has been acquired (used) to the series of travel information acquired from the series of travel information storage unit 12. When the next series of runs is started after the series of runs, the music data acquisition unit 14 converts the series of travel information to which the information indicating the acquisition is not given to the series of travel information storage unit 12. May be obtained from Moreover, the music data acquisition unit 14 may delete the series of travel information stored in the series of travel information storage unit 12 at the end of the series of travel, for example. The “end time” may be, for example, immediately before the end, may be simultaneously with the end, or may be immediately after the end. Moreover, the music data acquisition unit 14 may delete the series of travel information stored in the series of travel information storage unit 12 at the start of a series of travels, for example. The “starting time” may be, for example, immediately before the start, at the same time as the start, or immediately after the start. Then, when the next series of runs is started, the music data acquisition unit 14 acquires a series of run information newly accumulated and stored in the series run information storage unit 12.

  Further, for example, the music data acquisition unit 14 is stored in the music data storage unit 11 without using the series of travel information stored in the series of travel information storage unit 12 after the end of the series of travels. Any of the above music data may be acquired. The acquisition method in this case does not matter.

(25) indicates that music data is acquired when the time to the destination is equal to or less than the time obtained by dividing the route time information by 40. That is, “$ route time” is a variable indicating route time information. (26) indicates that music data is acquired when the current position falls within the distance range obtained by dividing the route distance information by 30 from the destination position. That is, “$ current position” is a variable indicating current position information. (27) indicates that the music data playback unit 15 described later acquires music data every time reproduction of music data ends. (28) indicates that music data is acquired at intervals of N minutes.

  Note that (21) to (26) are ending conditions that are conditions for determining whether or not the ending indicates the vicinity of the destination. The ending condition is a condition in which the position from the destination becomes farther as the distance of the route indicated by the route distance information becomes longer as in (24), (25), and (26). The position is a concept including distance and time.

  Also, (3) is, for example, (31) “random”, (32) “identifier, descending order”, (33) “size, ascending order”, (34) “normal”, and the like. (31) indicates that music data is randomly acquired. (32) indicates that the music data is acquired in descending order of the music data identifier.

(C) indicates that music data whose reproduction time is 3 minutes or more and less than 5 minutes is randomly acquired.

  The music acquisition method information may be a program that realizes acquisition of music data as described above, for example.

  The music acquisition method information acquisition unit 142 acquires, from the acquisition method management information storage unit 141, music acquisition method information corresponding to a music acquisition condition that matches the series of travel information stored in the series of travel information storage unit 12. In this case, the music acquisition method information acquisition unit 142 normally determines whether or not the series of travel information matches the music acquisition conditions.

  For example, when the series of travel information stored in the series of travel information storage unit 12 is route distance information, the music acquisition method information acquisition unit 142 supports a route distance condition that is a music acquisition condition that matches the route distance information. The music acquisition method information to be acquired is acquired from the acquisition method management information storage unit 141. In addition, for example, when the series of travel information stored in the series of travel information storage unit 12 is the number of times of reproduction, the music acquisition method information acquisition unit 142 is a number of times of reproduction that is a music acquisition condition that matches the number of times of reproduction of the information. Is acquired from the acquisition method management information storage unit 141.

  The music acquisition method information acquisition means 142 is a music acquisition method corresponding to a music acquisition condition in which the series of travel information stored in the series of travel information storage unit 12 matches the scene information acquired by the scene information acquisition unit 13. Information may be acquired from the acquisition method management information storage unit 141. In this case, the music acquisition method information acquisition unit 142 normally determines whether or not the series of running information and scene information match the music acquisition conditions.

  For example, when the route distance information is stored in the series travel information storage unit 12 and the scene information acquisition unit 13 acquires the scene information, the music acquisition method information acquisition unit 142 is stored in the series travel information storage unit 12. The music acquisition method information corresponding to the music acquisition condition that matches the existing route distance information and the scene information acquired by the scene information acquisition unit 13 is acquired from the acquisition method management information storage unit 141. For example, when the number of times of reproduction is stored in the series of travel information storage unit 12 and the scene information acquisition unit 13 acquires the scene information, the music acquisition method information acquisition unit 142 stores the information in the series of travel information storage unit 12. The music acquisition method information corresponding to the music acquisition conditions that match the playback count information and the scene information acquired by the scene information acquisition unit 13 is acquired from the acquisition method management information storage unit 141.

  For example, the acquisition method management information storage unit 141 stores acquisition method management information having a music acquisition condition “100 km ≦ route distance <200 km” and music acquisition method information “destination ≦ 200 m, music A”. . Further, it is assumed that route distance information “150 km” is stored in the series travel information storage unit 12. In this case, since the route distance information matches the music acquisition condition, the music acquisition method information acquisition unit 142 acquires music acquisition method information “destination ≦ 200 m, music A” corresponding to the music acquisition condition.

  Further, for example, the acquisition method management information storage unit 141 has a music acquisition condition “(music A, music B, music C) <3” and music acquisition method information “(music A, music B, music C)”. It is assumed that acquisition method management information is stored. Further, it is assumed that the number of reproduction times information “(music A = 1, music B = 2, music C = 3)” is stored in the series travel information storage unit 12. In this case, the music acquisition method information acquisition unit 142 obtains the music acquisition method information “(music A, music B, music C)” corresponding to the music acquisition condition because the reproduction number information matches the music acquisition condition. get.

  Also, for example, the acquisition method management information storage unit 141 stores acquisition method management information having a music acquisition condition “(route distance ≧ 100 km) & (road structure = tunnel)” and music acquisition method information “tunnel”. Suppose that Further, it is assumed that route distance information “150 km” is stored in the series travel information storage unit 12 and the scene information acquisition unit 13 acquires the road structure information “tunnel”. In this case, since the route distance information and the road structure information match the music acquisition condition, the music acquisition method information acquisition unit 142 acquires the music acquisition method information “tunnel” corresponding to the music acquisition condition.

  Further, for example, the acquisition method management information storage unit 141 stores the music acquisition condition “(number of reproductions (scene identifier: highway) = 0) & (road type = highway)” and the music acquisition method information “(number of reproductions = minimum number of times). ) & (Scene identifier = highway) ”is stored. Also, the series of travel information storage unit 12 stores the number-of-plays information “0” corresponding to the music data associated with the scene identifier “highway”, and the scene information acquisition unit 13 stores the road type information “highway”. It is assumed that “road” is acquired. In this case, the music acquisition method information acquisition unit 142 matches the music acquisition condition because the reproduction count information and the road type information match the music acquisition method information “(playback count = minimum)”. & (Scene identifier = highway) ”.

  Further, for example, it is assumed that the acquisition method management information storage unit 141 stores acquisition method management information having a music acquisition condition “none” and music acquisition method information “every end”. Further, it is assumed that a series of travel information is not stored in the series of travel information storage unit 12. In this case, the music acquisition method information acquisition unit 142 acquires the music acquisition method information “every end” corresponding to the music acquisition condition “none”.

  Further, the music acquisition method information acquisition unit 142 may acquire a series of travel information or scene information in accordance with the music acquisition conditions stored in the acquisition method management information storage unit 141. For example, the music acquisition method information acquisition unit 142 determines what the music acquisition condition indicates according to a predetermined order with respect to the music acquisition conditions stored in the acquisition method management information storage unit 141. To do. For example, when the music acquisition condition is a route distance condition related to the route distance information, the music acquisition method information acquisition unit 142 acquires the route distance information from the series of travel information storage unit 12. Further, for example, when the music acquisition condition is a reproduction frequency condition related to the reproduction frequency information, the music acquisition method information acquisition unit 142 acquires the reproduction frequency information from the series travel information storage unit 12. For example, when the music acquisition condition is a scene determination condition related to scene information, the music acquisition method information acquisition unit 142 acquires the scene information acquired by the scene information acquisition unit 13.

  The music data acquisition unit 143 acquires music data from the music data storage unit 11 in accordance with the music acquisition method information acquired by the music acquisition method information acquisition unit 142.

  For example, when the music acquisition method information acquisition unit 142 acquires the music acquisition method information “destination ≦ 200 m, music A”, the music data acquisition unit 143 displays the music data when the distance to the destination is 200 m or less. The music data identified by the identifier “music A” is acquired from the music data storage unit 11. In this case, the music data acquisition unit 143 determines, for example, whether or not the distance to the destination is 200 m or less using the destination distance information acquired by the scene information acquisition unit 13.

  Further, for example, when the music acquisition method information acquisition unit 142 acquires the music acquisition method information “destination ≦ $ route distance ÷ 25, ending”, the music data acquisition unit 143, for example, the route included in the music acquisition method information The route distance information stored in the series travel information storage unit 12 is substituted into the variable “$ route distance” indicating the distance information, and new music acquisition method information is acquired. For example, when the route distance information is “100 km”, the music data acquisition unit 143 calculates “100 km ÷ 25” and acquires new music acquisition method information “destination ≦ 4 km, ending”. The music data acquisition unit 143 acquires the music data identified by the scene identifier “ending” from the music data storage unit 11 when the distance to the destination is 4 km or less.

  For example, when the music acquisition method information acquisition unit 142 acquires the music acquisition method information “number of times of reproduction = minimum”, the music data acquisition unit 143 reproduces each piece of music data stored in the series of travel information storage unit 12. One of the music data with the smallest number of reproductions indicated by the frequency information is acquired from the music data storage unit 11.

  For example, when the music acquisition method information acquisition unit 142 acquires the music acquisition method information “(music A, music B, music C)”, the music data acquisition unit 143 is stored in the music data storage unit 11. Among the song data, the song data identified by the song data identifiers “Song A”, “Song B”, and “Song C” are acquired.

  In addition, for example, when the music acquisition method information acquisition unit 142 acquires the music acquisition method information “every end”, the music data acquisition unit 143 causes the music data acquisition unit 143 to play the music every time the music data playback unit 15 described later ends the playback of the music data. Get the data.

  The music data reproducing unit 15 reproduces the music data acquired by the music data acquiring unit 14. In addition, the music data reproducing unit 15 obtains reproduction number information indicating the number of reproductions of each piece of music data obtained by the music data obtaining unit 14 and accumulates the reproduction number information in the series travel information storage unit 12. The “acquisition of reproduction number information” includes, for example, counting the number of reproductions of the music data, incrementing the number of reproductions of the music data, and the like. Further, the timing of accumulating the reproduction count information is not limited. For example, it may be immediately before the start of playback, may be immediately after the start of playback, may be immediately before the end of playback, or may be immediately after the end of playback. Further, the music data reproducing unit 15 may acquire the number-of-plays information immediately after the music data is reproduced for a predetermined time or more, and accumulate the information on the number of times of reproduction in the series travel information storage unit 12, for example. In addition, the music data reproducing unit 15 usually accumulates the number of times of reproduction in association with the music data identifier of the music data to be reproduced.

  The music data playback unit 15 may or may not include an output device such as a speaker. The music data reproducing unit 15 can be realized by driver software of an output device or driver software of an output device and an output device.

  The music data storage unit 11, the series running information storage unit 12, and the acquisition method management information storage unit 141 are preferably non-volatile recording media, but can also be realized by volatile recording media.

  In addition, the music data acquisition unit 14, the music acquisition method information acquisition unit 142, and the music data acquisition unit 143 can be usually realized by an MPU, a memory, or the like. The processing procedure of the music data acquisition unit 14 and the like is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  Next, the operation of the in-vehicle device 1 will be described. Note that the i-th information in the predetermined information is described as “information [i]”. FIG. 2 is a flowchart showing the overall operation of the in-vehicle device 1.

  (Step S207) The music acquisition method information acquisition unit 142 determines whether i is m. When it is m, it progresses to step S209, and when that is not right, it progresses to step S208.

  (Step S208) The music acquisition method information acquisition unit 142 increments i by 1.

  (Step S209) The music data acquisition means 143 determines whether it is the timing of acquisition of music data according to the music acquisition method information acquired in step S206. If it is the acquisition timing, the process proceeds to step S210, and if not, the process returns to step S209.

  (Step S210) The music data acquisition unit 143 acquires music data from the music data storage unit 11 in accordance with the music acquisition method information acquired in step S206.

  (Step S211) The music data playback unit 15 plays back the music data acquired in step S210.

The in-vehicle device 2 includes a music data storage unit 11, a series of travel information storage unit 12, a scene information acquisition unit 13, a determination unit 26, a music data acquisition unit 24, and a music data reproduction unit 15. The music data acquisition unit 24 includes an acquisition method management information storage unit 241, a music acquisition method information acquisition unit 242, and a music data acquisition unit 243.

  The determination unit 26 determines whether or not the traveling of the moving body is a series of traveling. The determination unit 26 usually acquires travel-related information related to the travel of the mobile body, and determines whether the travel-related information matches a series of travel conditions, whereby the travel of the mobile body is a series of travels. It is determined whether or not. The series of traveling conditions are conditions for determining whether or not the traveling of the moving body is a series of traveling. For example, when the travel related information matches a series of travel conditions, the determination unit 26 determines that the travel of the moving body is a series of travel. For example, when the travel-related information does not match the series of travel conditions, the determination unit 26 determines that the travel of the moving body is not a series of travels. The series of driving conditions is normally held by the determination unit 26, but may be stored in an arbitrary storage area.

  The travel related information is, for example, position related information related to the position of the mobile object when traveling, state related information related to the state of the mobile object when traveling, time related information related to the time of travel of the mobile object, etc. It is. The travel related information is usually information related to the current travel of the mobile object.

  The position related information is, for example, current position information indicating a current position at the time of traveling, road information indicating a road that is traveling, point distance information indicating a distance from the current position to a predetermined point, and the like. The current position information is usually longitude and latitude information indicating longitude and latitude, but may be coordinate information indicating coordinates on a map, altitude information indicating altitude, and the like. The point distance information may be a distance from a predetermined point to the current position. The state-related information includes, for example, engine information indicating the ON / OFF state of the moving body engine, remaining fuel information indicating the remaining fuel amount of the moving body, and speed information indicating the speed of the moving body. The time-related information is, for example, time information indicating time, time zone information indicating a time zone, time information indicating a time from a certain time to a certain time, and the like.

  In addition, the series of travel conditions include, for example, (1) conditions regarding the route on which the mobile body travels, (2) conditions regarding the travel state of the mobile body, (3) conditions regarding the travel time of the mobile body, etc. It is. Further, the traveling-related condition may be a combination of these conditions.

  (1) is, for example, (11) “travel = (departure point → destination)”, (12) “travel = (departure point → destination | destination → departure point)”, (13) “current position = On the route ”, (14)“ current position = {(N34.23, E135.35), (N34.46, E135.59)} ”. (11) indicates that the traveling of the moving body is traveling from the departure place to the destination (the moving body is traveling on the route from the departure place to the destination). (12) is that the moving body travels from the departure point to the departure point via the destination (the moving body is traveling on the route from the departure point to the departure point via the destination). Show). (13) indicates that the current position of the moving body is on a predetermined route. (14) indicates that the current position of the moving object is within the range of “(N34.23, E135.35), (N34.46, E135.59)” (the moving object is within a predetermined range). Is).

  (2) is, for example, (21) “Engine = ON”, (22) “Speed ≧ 30 km / h”, (23) “Remaining fuel ≧ 5 L”, and the like. (21) indicates that the engine of the moving body is ON (the traveling of the moving body is the travel from when the engine of the moving body starts until the engine stops). Further, (22) indicates that the speed of the moving body is 30 km / h or more. Further, (23) indicates that the fuel remaining amount of the moving body is 5L or more.

  (3) is, for example, (31) “non-travel time ≦ 30 minutes”, (32) “travel time ≧ 2 hours”, (33) “engine ON ≧ 1 hour”, (34) “non-route” Top ≦ 30 minutes ”. (31) indicates that the time during which the moving object is not traveling is within 30 minutes. That is, (31) indicates that the non-running time of the moving body is equal to or shorter than a predetermined time. Further, (32) indicates that the time during which the moving body is traveling is 2 hours or more. Further, (33) indicates that the time during which the engine of the moving body is ON is 1 hour or longer. In addition, (34) indicates that the position of the moving body is within 30 minutes that is off the predetermined route.

  For example, the determination unit 26 acquires the current position information, and whether or not the current position information matches the route position information included in the route information stored in the series of travel information storage units 12 or whether the route information is It is determined whether or not it is included in the range indicated by the route position information. And the judgment part 26 judges that driving | running | working of a mobile body is a series of driving | running | working, when it corresponds or is contained. A series of traveling conditions in this case is, for example, “current position = on the route”.

  In addition, for example, the determination unit 26 acquires the point distance information to the destination twice or more at certain intervals, and determines whether or not the mobile object is approaching the destination from the two or more point distance information. And the judgment part 26 judges that driving | running | working of a moving body is a series of driving | running | working, when the said approach is approaching. The series of travel conditions in this case is, for example, “travel = (starting place → destination)”.

  For example, the determination unit 26 acquires engine information and determines whether the engine information indicates that the engine is ON. And the judgment part 26 judges that driving | running | working of a mobile body is a series of driving | running | working, when showing that the said engine is ON. The series of traveling conditions in this case is, for example, “engine = ON”.

  Further, for example, the determination unit 26 acquires time information indicating the time when the engine is turned on, acquires time information indicating the elapsed time from the time, and whether or not the time satisfies a predetermined condition. Determine whether. And the judgment part 26 judges that driving | running | working of a mobile body is a series of driving | running | working, when satisfy | filling the said said. The series of traveling conditions in this case is, for example, “engine ON ≧ 1 hour”.

  Further, for example, the determination unit 26 acquires speed information, and the speed information determines whether or not the speed of the moving object is greater than zero. And the judgment part 26 judges that the speed of a moving body is a series of driving | running | working, when the speed of the said moving body is larger than zero. The series of traveling conditions in this case is, for example, “speed> 0”.

  Further, for example, the determination unit 26 acquires time information indicating the time when the speed of the moving body becomes “0”, acquires time information indicating the elapsed time from the time, and the time is determined in advance. Determine whether the condition is met. And the judgment part 26 judges that driving | running | working of a mobile body is a series of driving | running | working, when satisfy | filling the said said. The series of traveling conditions in this case is, for example, “speed 0 ≦ 1 hour”.

  Further, for example, after determining that the travel of the mobile body is a series of travels, when the travel-related information does not match the series of travel information, the determination unit 26 performs the series of travels up to the time when the travel no longer matches. It may be determined that the vehicle has traveled, or the travel up to the point of no longer matching may not be determined as a series of travels.

  For example, while the moving body is traveling on the route, the determination unit 26 determines that the traveling is a series of traveling based on the above determination. And when a mobile body deviates from the said path | route, the judgment part 26 judges that the said driving | running | working is not a series of driving | running | working by the above determinations.

  Moreover, the determination part 26 may acquire traveling related information according to a series of traveling conditions, for example. For example, the determination unit 26 determines what the series of travel conditions indicate according to a predetermined order with respect to the series of travel conditions. For example, when the series of traveling conditions is a position-related condition that is a condition related to the position of the moving body, the determination unit 26 acquires position-related information. Further, for example, when the series of traveling conditions is a state-related condition that is a condition related to the state of the moving object, the determination unit 26 acquires the state-related information. For example, when the series of travel conditions is a time-related condition that is a condition related to time, the determination unit 26 acquires time-related information.

  Note that the determination unit 26 normally continues to acquire travel-related information immediately after the power source of the in-vehicle device 2 is turned on until the power source is turned off. The acquisition timing is usually regular such as every second, every 10 minutes, or every hour, but may be irregular. Moreover, the timing of acquisition of traveling related information may be determined in advance for each of various traveling related information.

  The determination unit 26 usually measures the speed of a satellite navigation system (such as a GPS receiver), a device that receives position information from a base station for mobile communication, an ignition sensor that detects whether the engine is on or off, and the speed of the mobile body. Various travel-related information is acquired from a speedometer, a fuel remaining amount meter that measures the remaining fuel amount of the moving body, a clock, and the like. In this case, the determination unit 26 may have these devices or may be realized by these devices. In addition, the determination unit 26 may acquire the various traveling-related information from, for example, a predetermined storage area in which various traveling-related information is stored or an arbitrary storage area. The determination unit 26 may be realized by an MPU, a memory, or the like. In this case, the processing procedure of the determination unit 26 is usually realized by software, and the software is recorded on a recording medium such as a ROM.

  The music data acquisition unit 24 stores the music data using the series of travel information stored in the series of travel information storage units 12 when the determination unit 26 determines that the travel of the moving body is a series of travels. Music data is acquired from the unit 11. In addition, when the determination unit 26 determines that the traveling of the moving body is not a series of runs, the music data acquisition unit 24 does not use the used series of travel information. At this time, the music data acquisition unit 24 may acquire the music data from the music data storage unit 11 without using the series of travel information, for example, or may not acquire the music data.

  The processing performed by the music data acquisition unit 24 is the same as that of the music data acquisition unit 14 described above except that the determination unit 26 acquires music data when the mobile object travel is determined to be a series of travels. Since this is the same as the processing, the description is omitted. Also, the acquisition method management information storage unit 241, the music acquisition method information acquisition unit 242, the processing performed by the music data acquisition unit 243, etc., included in the music data acquisition unit 24, respectively, store the acquisition method management information included in the music data acquisition unit 14. Since the processing is the same as the processing performed by the means 141, the music acquisition method information acquisition means 142, and the music data acquisition means 143, description thereof will be omitted.

  Next, the operation of the in-vehicle device 2 will be described. Note that the i-th information in the predetermined information is described as “information [i]”. FIG. 7 is a flowchart showing the overall operation of the in-vehicle device 2. In the flowchart of FIG. 2, it is assumed that the acquisition method management information storage unit 241 stores m acquisition method management information. In the flowchart of FIG. 7, steps S705 to S715 are the same as steps 203 to S213 of the flowchart of FIG.

  (Step S701) The music acquisition method information acquisition unit 242 acquires a series of travel information stored in the series of travel information storage unit 12.

  (Step S702) The scene information acquisition unit 13 acquires scene information. Thereafter, the scene information acquisition unit 13 continues to acquire scene information.

  (Step S703) The determination unit 26 acquires travel-related information.

  (Step S704) The determination unit 26 determines whether or not the travel-related information acquired in Step S703 matches a series of travel conditions stored in an arbitrary storage area. If they match, the process proceeds to step S705, and if not, the process returns to step S701.

  In the flowchart of FIG. 7, the process may be terminated by powering off or a process termination interrupt.

(Concrete example)
Next, a specific example of the operation of the in-vehicle device 2 will be described. In this specific example, the in-vehicle device 2 is a navigation device integrated with an audio device, and is mounted on an automobile. Further, it is assumed that a series of traveling conditions shown in FIG. 8 is stored in an arbitrary storage area. The series of travel conditions (item name: series of travel conditions) is associated with an ID (item name: ID) for uniquely identifying the record. The music data storage unit 11 stores the music data shown in FIG. 3 and the acquisition method management information storage unit 241 stores the acquisition method management information shown in FIG. Since the procedure and method for acquiring the music acquisition method information are the same as those in the specific example of the first embodiment, description thereof will be omitted. In this specific example, only a specific example of determination performed by the determination unit 26 as to whether the traveling of the moving body is a series of traveling will be described.

  First, it is assumed that the user (driver) operates the navigation device and sets the point A as the destination. Then, a route search unit (not shown) searches for a route from the current location to the point A, and route information that is a result of the route search is accumulated in the series of travel information storage unit 12. Hereinafter, the route information is referred to as a route A because it indicates a route to the destination point A.

  Next, it is assumed that the automobile is traveling on the route indicated by the route A. Then, the determination unit 26 acquires current position information indicating the current position of the automobile, and acquires current position information “(N35.79, E135.79)”. The determination unit 26 also acquires the route information.

  Next, the determination unit 26 determines whether or not the current position information “(N35.79, E135.79)” matches the path position information included in the path A, or is included in the range indicated by the path position information. It is assumed that it is determined whether or not they match. As a result, the determination unit 26 determines that the acquired travel-related information matches the series of travel conditions “ID = 011” in FIG. 8. That is, the determination unit 26 determines that the current traveling of the automobile is a series of traveling.

  Here, for example, it is assumed that the automobile is off route A. At this time, the route search unit does not perform reroute. Then, the determination unit 26 measures the elapsed time from immediately after leaving the route A until returning to the route A. When the elapsed time is within 30 minutes, the determination unit 26 determines that the traveling of the automobile is a series of traveling because the elapsed time matches the series of traveling conditions of “ID = 012” in FIG. 8. To do. If the elapsed time exceeds 30 minutes, the determining unit 26 determines that the travel-related information such as the elapsed time and the current position information does not match any of the series of travel conditions in FIG. Judge that it is not a series of runs.

  First, for example, it is assumed that a user (driver) turns on an automobile engine and starts traveling without setting a destination. Then, the determination unit 26 acquires engine information “ON”.

  Next, the determination unit 26 determines that the engine information “ON” matches the series of travel conditions “ID = 014” in FIG. 8. That is, the determination unit 26 determines that the current traveling of the automobile is a series of traveling.

  Here, for example, it is assumed that the user parks a car in a parking lot of a convenience store and turns off the engine. Then, the determination unit 26 measures an elapsed time from when the engine is turned off until the engine is turned on. When the elapsed time is within one hour, the determination unit 26 determines that the traveling of the automobile is a series of traveling because the elapsed time matches the series of traveling conditions of “ID = 015” in FIG. To do. If the elapsed time exceeds 1 hour, the determining unit 26 determines that the travel-related information such as the elapsed time and the current position information does not match any of the series of travel conditions in FIG. Judge that it is not a series of runs.
