  When the location including the current position of the automobile 100 is a seaside or the like other than an urban area, the channel setting unit 7 reads the broadcast station information BCIF1 and the like from the database DB1 and the like, and selects the radio broadcast stations A to F by the same method as described above. Channels CHA to CHF for channel selection are set in the channel selection buttons 81 to 86.

  In this way, the channel setting unit 7 is arranged in the order of the longest total reception time in the direction in which the six channels CHA to CHF are away from the side closer to the handle 101 in a place (seaside or the like) including the current position of the automobile 100. 6 channels CHA to CHF are set to the channel selection buttons 81 to 86.

  FIG. 5 is another conceptual diagram of the database stored in the data storage unit 6 shown in FIG. The database DB3 includes broadcast station information BCIF3 'instead of the broadcast station information BCIF3. Broadcast station information BCIF3 ′ includes radio broadcast stations C, D, E, F, A, and B, and total times (= total reception times) associated with radio broadcast stations C, D, E, F, A, and B, respectively. ) 5:00: 00, 4:00: 00, 3:00: 00, 3:00: 00, 1:00: 00, 0:00: 00. Therefore, the broadcast station information BCIF3 ′ has the longest total radio broadcast reception time from the radio broadcast station C, the second longest radio broadcast reception time from the radio broadcast station D, and the radio broadcast stations E and F. The total reception time of radio broadcasts is the third longest and the same, the total reception time of radio broadcasts from radio broadcast station A is the fourth longest, and the total reception time of radio broadcasts from radio broadcast station B Indicates the shortest.

  As described above, the broadcast station information BCIF 3 'includes a plurality of radio broadcast stations having the same total reception time.

  A case where the channels CHA to CHF are set to the channel selection buttons 81 to 86 based on the broadcast station information BCIF3 'will be described. When the handle 101 is the right handle, the channel setting unit 7 sets the channel CHC for selecting the radio broadcast station C to the channel selection button 86 and selects the channel CHD for selecting the radio broadcast station D. The channel button 85 is set, the channel CHF for selecting the radio broadcast station F is set to the channel selection button 84, the channel CHE for selecting the radio broadcast station E is set to the channel selection button 83, and the radio The channel CHA for selecting the broadcast station A is set to the channel selection button 82, and the channel CHB for selecting the radio broadcast station B is set to the channel selection button 81.

  Further, when the handle 101 is the left handle, the channel setting unit 7 sets the channel CHC for selecting the radio broadcasting station C to the channel selection button 81 and the channel CHD for selecting the radio broadcasting station D. Is set to the channel selection button 82, the channel CHF for selecting the radio broadcast station F is set to the channel selection button 83, and the channel CHE for selecting the radio broadcast station E is set to the channel selection button 84. The channel CHA for selecting the radio broadcast station A is set to the channel selection button 85, and the channel CHB for selecting the radio broadcast station B is set to the channel selection button 86.

Thus, when the total reception time of radio broadcasts from the radio broadcast stations E and F is the same, the channel CHF for selecting the radio broadcast station F is more than the channel CHE for selecting the radio broadcast station E. The channel selection button on the side closer to the handle 101 is set. This is because the frequency f _F of the radio broadcast from the radio broadcast station _F is higher than the frequency f _E of the radio broadcast from the radio broadcast station E as described above.

  In other words, in the present invention, when there are a plurality of broadcasting stations having the same total reception time, the channel setting unit 7 selects the plurality of channels for selecting the plurality of broadcasting stations from the side closer to the handle 101. A plurality of channels are set to a plurality of channel selection buttons so that radio broadcast frequencies are arranged in descending order in the direction away from each other.

  FIG. 6 is a conceptual diagram for explaining a method of updating the database stored in the data storage unit 6 shown in FIG. The data storage unit 6 holds databases DB1 to DB6 for storing the broadcast station information BCIF1 to BCIF6 (see (a) of FIG. 6), and the channel setting unit 7 is a broadcasting station in each place such as seaside. Based on the information BCIF1 and the like, channels CHA to CHF for selecting radio broadcast stations A to F are set in the channel selection buttons 81 to 86 by the method described above.

  When the channels CHA to CHF are set to the channel selection buttons 81 to 86, the driver 20 usually presses the channel selection button 81 or 86 on the side closest to the handle 101 at each place, so that the total reception time is the shortest. Select a long radio station. For example, when the place where the automobile 100 is traveling is a residential area, the driver 20 usually selects the radio broadcasting station E by pressing the channel selection button 81 or 86.

Then, the channel unit 8 outputs a signal indicating that the channel CHE for selecting the radio broadcasting station E has been selected to the control unit 3 via the bus BS, and the control unit 3 outputs the channel CHE, that is, controls the reception unit 1 to receive a radio frequency f _E, it controls the timer 9 to measure the time. Then, the timer 9 starts measuring time.

After that, after the driver 20 listens to the radio broadcast from the radio broadcast station E for 3 hours, when the channel selection button 82 or 85 for selecting the radio broadcast station F is pressed, the channel unit 8 is switched to the radio broadcast station F. A signal indicating that the channel CHF for selecting the channel is selected is output to the control unit 3 via the bus BS, and the control unit 3 receives the channel CHF, that is, the radio broadcast of the frequency f _F. While controlling the receiver 1, the timer 9 is controlled so as to output the measured time.

  And the control part 3 receives measurement time T1 from the timer 9, detects that the driver | operator 20 listened to the radio broadcast from the radio broadcasting station E for 3 hours, and the detected 3 hours are used as a residential area. Is added to the total reception time (= 5: 00: 00) of the radio broadcast station E in the database DB5 corresponding to the above, and the total reception time of the radio broadcast station E is updated to 8:00: 00 to broadcast the broadcast station information BCIF5. The station information is updated to BCIF5 ′ (see FIG. 6B).

Thereafter, when the driver 20 listens to the radio broadcast from the radio broadcast station F for one hour and then presses the channel selection button 83 or 84 for selecting the radio broadcast station A, the channel unit 8 a signal indicating that the channel CHA has been selected for tuning and outputting to the control unit 3 via the bus BS, the control unit 3, the channel CHA, i.e., to receive a radio frequency f _a While controlling the receiver 1, the timer 9 is controlled so as to output the measured time.

  And the control part 3 receives measurement time T2 from the timer 9, detects that the driver | operator 20 listened to the radio broadcast from the radio broadcasting station F for 1 hour, and the detected 1 hour is used as a residential area. Is added to the total reception time (= 4: 00: 00) of the radio broadcast station F in the database DB5, and the total reception time of the radio broadcast station F is updated to 5:00: 00, and the broadcast station information BCIF5 ′ is updated. The broadcast station information is updated to BCIF5 ″ (see (c) of FIG. 6).

In this case, the control unit 3 receives the radio broadcast of the frequency f _F from the measurement time T2 received from the timer 9 when the reception unit 1 is controlled to receive the radio broadcast of the frequency f _A. By subtracting the measurement time T1 received from the timer 9 when the control is performed, it is detected that the time when the driver 20 listens to the radio broadcast from the radio broadcast station F is one hour.

  Thereafter, by repeating the above-described operation, the control unit 3 sequentially updates the broadcast station information BCIF5 ″ of the database DB5 corresponding to the residential area.

  Even when the place where the automobile 100 is traveling is a place other than a residential area, the broadcast station information BCIF1 to BCIF4 and BCIF6 of the databases DB1 to DB4 and DB6 corresponding to each place are sequentially updated according to the above-described operation.

  FIG. 7 is another conceptual diagram for explaining a method of updating the database stored in the data storage unit 6 shown in FIG. The data storage unit 6 stores databases DB1 to DB6 composed of broadcast station information BCIF1 to BCIF6 (see FIG. 7A), and the channel setting unit 7 is broadcast station information at each location such as seaside. Channels CHA to CHF for selecting radio broadcast stations A to F based on BCIF1 and the like are set in the channel selection buttons 81 to 86 by the method described above.

  When the channels CHA to CHF are set to the channel selection buttons 81 to 86, the driver 20 usually presses the channel selection button 81 or 86 on the side closest to the handle 101 at each place, so that the total reception time is the shortest. Select a long radio station. For example, when the place where the automobile 100 is traveling is an urban area, the driver 20 usually selects the radio broadcasting station D by pressing the channel selection button 81 or 86.

However, the driver 20 may select a radio broadcasting station whose total reception time is the second or later depending on the mood. For example, the driver 20 may select the radio broadcast station A having the fourth longest total reception time depending on the mood. When the driver 20 presses the channel selection button 84 or 83 for selecting the radio broadcast station A, the channel unit 8 outputs a signal indicating that the channel CHA for selecting the radio broadcast station A is selected. The signal is output to the control unit 3 via the bus BS. The control unit 3 controls the reception unit 1 so as to receive the radio broadcast of the channel CHA, that is, the frequency f _A , and sets the timer 9 so as to measure the time. Control. Then, the timer 9 starts measuring time.

After that, when the driver 20 listens to the radio broadcast from the radio broadcast station A for 5 hours and then presses the channel selection button 81 or 86 for selecting the radio broadcast station D, the channel unit 8 is switched to the radio broadcast station D. a signal indicating that the channel CHD is selected for tuning and outputting to the control unit 3 via the bus BS, the control unit 3, channel CHD, i.e., to receive a radio frequency f _D While controlling the receiver 1, the timer 9 is controlled so as to output the measured time.

  And the control part 3 receives measurement time T3 from the timer 9, detects that the driver | operator 20 listened to the radio broadcast from the radio broadcasting station A is 5 hours, and the detected 5 hours are set to a city area. The total reception time of radio broadcast station A is updated to 7:00 by adding to the total reception time (= 2: 00: 00) of radio broadcast station A in the corresponding database DB4, and the broadcast station information BCIF4 is updated to the broadcast station. Information BCIF4 ′ is updated (see FIG. 7B).

  Then, the control unit 3 refers to the broadcast station information BCIF4 ′, detects that the total reception time (= 7: 00: 00: 00) of the radio broadcast station A is the longest, and the six broadcast stations A to F are detected. Broadcast station information BCIF4 ′ is updated to broadcast station information BCIF4 ″ so as to be arranged in the order of the longest total reception time (see FIG. 7C).

  And the control part 3 controls the channel setting part 7 to update the setting to the channel selection buttons 81-86 of channels CHA-CHF, and the channel setting part 7 is based on broadcast station information BCIF4 ''. The settings for the channel selection buttons 81 to 86 of the channels CHA to CHF are updated.

  More specifically, when the handle 101 is the right handle, the channel setting unit 7 sets the channel CHA for selecting the radio broadcast station A in the channel selection button 86 based on the broadcast station information BCIF4 ″. Then, the channel CHD for selecting the radio broadcast station D is set to the channel selection button 85, the channel CHE for selecting the radio broadcast station E is set to the channel selection button 84, and the radio broadcast station F is selected. The channel CHF for station selection is set to the channel selection button 83, the channel CHB for channel selection of the radio broadcast station B is set to the channel selection button 82, and the channel CHC for channel selection of the radio broadcast station C is selected. The station button 81 is set.

  Further, when the handle 101 is the left handle, the channel setting unit 7 sets the channel CHA for selecting the radio broadcast station A to the channel selection button 81 based on the broadcast station information BCIF4 ″, and performs radio broadcast. The channel CHD for selecting the station D is set in the channel selection button 82, the channel CHE for selecting the radio broadcast station E is set in the channel selection button 83, and the radio broadcast station F is selected. The channel CHF is set to the channel selection button 84, the channel CHB for selecting the radio broadcast station B is set to the channel selection button 85, and the channel CHC for selecting the radio broadcast station C is set to the channel selection button 86. Set.

  Thereafter, similarly, the control unit 3 updates the broadcast station information by updating the total reception time of the radio broadcast from the radio broadcast station selected according to the mood of the driver 20, and the channel setting unit 7 Based on the broadcast station information, the settings for the channel selection buttons 81 to 86 of the channels CHA to CHF are updated.

  Even when the place where the automobile 100 is traveling is a place other than the urban area, the broadcast station information BCIF1 to BCIF3, BCIF5, and BCIF6 stored in the databases DB1 to DB3, DB5, and DB6 are updated according to the above-described operation.

  FIG. 8 is a flowchart for explaining the operation of the car audio 10 shown in FIG. When a series of operations is started, the position detection unit 4 receives position information from the satellite 11, reads map data from the map data storage unit 5, superimposes the position information on the map data, and presents the current vehicle 100. The position is detected (step S1).

  Then, the position detection unit 4 outputs the detected current position of the automobile 100 to the control unit 3. When the control unit 3 receives the current position of the automobile 100 from the position detection unit 4, the map detection unit 4 reads the map from the map data storage unit 5. The data is read to detect a location including the current position of the automobile 100, and a location that matches the detected location is selected from six locations such as seaside (step S2).

  Thereafter, the control unit 3 outputs the selected location to the channel setting unit 7, and the channel setting unit 7 broadcasts station information from a database (any one of the databases DB 1 to DB 6) corresponding to the location received from the control unit 3. (One of the broadcast station information BCIF1 to BCIF6) is read out (step S3), and n (n is an integer of 2 or more) channels from the side closer to the handle 101 of the automobile 100 based on the read broadcast station information. N channels are set to a plurality of channel selection buttons so as to be arranged in order of increasing total reception time in a direction away from each other (step S4).

  Thereafter, the car audio 10 measures the reception time of receiving the radio broadcast from the selected radio broadcast station at the selected location by the method described above, and adds the measured reception time to the selected radio. The total reception time of the radio broadcast from the broadcast station is updated (step S5).

  Then, the control unit 3 of the car audio 10 determines whether or not the updated total reception time Ttotal1_renew is longer than the total reception time Ttotal2_no-renew of another broadcasting station that is longer than the total reception time Ttotal1_no-renew before the update. When the updated total reception time Ttotal1_renew is longer than the total reception time Ttotal2_no-renew before the update, the control unit 3 updates the broadcast station information corresponding to the selected location by the method described above. (Step S7), the channel setting unit 7 updates the settings for the plurality of channel selection buttons of n channels based on the updated broadcast station information.

  Thereafter, the series of operations returns to step S4, and the above-described steps S4 to S7 are repeatedly executed. In step S6, it is determined that the updated total reception time Ttotal1_renew is not longer than the total reception time Ttotal2_no-renew. And a series of operation | movement is complete | finished.

  The flowchart shown in FIG. 8 is always executed, and the total reception time is long in the direction away from the side closer to the handle 101 (that is, the side closer to the driver 20) in each place such as the seaside where the automobile 100 is traveling. In order, n channels are set to a plurality of channel selection buttons.

  The relatively long total reception time means that the time that the driver 20 listens to the radio broadcast is relatively long, and the degree of preference of the driver 20 is relatively large. Therefore, in step S4 of the flowchart shown in FIG. 8, n channels are set to a plurality of channel selection buttons so that the n channels are arranged in the order of long total reception time away from the side closer to the handle 101. This corresponds to setting the n channels to a plurality of channel selection buttons so that the n channels are arranged in descending order of preference in a direction away from the side closer to the handle 101.

  Then, the flowchart shown in FIG. 8 is executed, so that in each place where the automobile 100 is traveling, the preference degree increases in the direction away from the side closer to the handle 101 (that is, the side closer to the driver 20). n channels are set to a plurality of channel selection buttons.

  Therefore, when the driver 20 selects a radio broadcast station that performs a radio broadcast with a relatively high degree of preference at each location, the driver 20 sequentially presses the channel selection buttons arranged on the side closest to the driver 20. Well, the radio broadcast station that the driver 20 likes can be easily selected.

  Further, when the driver 20 selects each radio broadcast station, the driver 20 only needs to press one channel selection button (that is, only needs to press the channel selection button once). You can tune in.

  When the operation of the car audio 10 is executed according to the flowchart shown in FIG. 8, a CPU (Central Processing Unit) built in the car audio 10 reads a program from a ROM (Read Only Memory), and reads the read program. The operation of the car audio 10 is performed according to the flowchart shown in FIG. Therefore, the flowchart shown in FIG. 8 constitutes a “program” for causing a computer (CPU) to execute the operation of the car audio 10. The ROM constitutes a “recording medium” that can be read by a computer (CPU) in which a program for causing the computer to execute the operation of the car audio 10 is recorded.

  When this program causes the computer (CPU) to execute the operation of the car audio 10, the program detects the current position of the automobile 100 by the position detection unit 4 in step S1.
