The “Time Correction” button 83b is a button selected when adjusting the delay of the speaker. The “X-Over” button 83c is a button that is selected when adjusting the output frequency characteristics of the amplifier.

  Among these selection buttons (81, 82, 83a to 83c), when the “acoustic data download” button 82 is selected, it is determined that there is a request for downloading the acoustic data.

  In the next step S22, the information center 50 is accessed. The audio control unit 15 controls the communication control unit 16 to send a download request signal to the in-vehicle LAN 14, and the in-vehicle server control unit 31 controls the communication control unit 33 to transmit the download request signal to the information center 50. To do. The information center 50 that has received the download request signal transmits the acoustic data stored in the server storage unit 53 toward the in-vehicle acoustic device 40.

  In the next step S23, the acoustic data is downloaded from the information center 50 and stored in the memory of the in-vehicle server 30. In this process, all the acoustic data registered in the server storage unit 53 of the information center 50 are stored in the memory.

  In the next step S24, the in-vehicle server control unit 31 compares the profile data of the own vehicle with the profile data of the downloaded acoustic data. In this comparison, it is determined whether or not the values of the vehicle type and the like match for each element constituting the profile data, and the degree of approximation (matching rate) of the entire profile data is calculated. For example, if all 15 elements such as age and vehicle type match, the matching rate is 100%.

  In the next step S25, the acoustic data identification name (user name at the time of registration, etc.) is displayed on the screen of the display device 22 together with the matching rate. FIG. 6B shows an acoustic data selection screen 90a in which the acoustic data is downloaded from the server storage unit 53 of the information center 50 and stored in the memory, and the user name is displayed as a list together with the matching rate.

  On the acoustic data selection screen 90a, recommended recommended acoustic data (user name) and individual menus for manual search ("vehicle information" button 86a, "device information" button 86b, "user characteristics" button 86c) are displayed. ing. In the recommended acoustic data, the user name 84 for identifying the profile and the matching rate 85 corresponding to the profile are displayed in descending order of the matching rate by comparing the profile of the own vehicle with the profile of the registered other user.

  In the next step S26, it is determined whether or not a user name has been selected. When the user name is selected, the process proceeds to step S27. When one of the identification buttons 84 in FIG. 6B is selected, it is determined that a user name has been selected.

  In the next step S27, acoustic parameters are set according to the acoustic setting data of the selected user name. When a specific user name is selected in step S26, an acoustic data download preparation screen 90b shown in FIG. 7A is displayed. On the acoustic data download preparation screen 90b, the selected user name 87 is displayed together with the matching rate 88, and the contents of profile components such as “car type” and “genre to listen to” are displayed. When the user confirms the profile of the selected user name and selects the “download” button 89, the acoustic data associated with the profile is downloaded.

  With the above processing, the sound field environment is set based on the acoustic data set under conditions close to those of the host vehicle and the user. Thereafter, the user can actually operate the audio device to listen to the sound, and use it as it is in a desired sound field environment.

  Further, if the acquired sound based on the sound field environment is not a desired sound, another registered acoustic data may be selected. At that time, the acoustic data recommended by the in-vehicle acoustic device 40 may be used, or another acoustic data may be searched by narrowing down the search condition to the vehicle type or the characteristics of the user.

  FIG. 7B shows an acoustic data search screen 90c displayed when the “vehicle information” button 86a in the manual search is selected from the acoustic data selection screen 90a of FIG. 6B. The acoustic data search screen 90c in this case uses vehicle information as a search key, and selects vehicle-specific data. As information unique to the vehicle, “manufacturer” 91a, “vehicle type” 91b, “type” 91c, “year” 91d, and “seat material” 91e can be selected from the pull-down menus. After setting the information unique to each vehicle in the menu, when a “search start” button 92 is selected, a search result is displayed. As the search result, for example, a list of user names that match the search conditions is displayed, and when a user name is selected, an acoustic data download preparation screen similar to FIG. 7A is displayed, and the download button is selected. Thus, the acoustic data is downloaded.

  The in-vehicle acoustic device 40 sets the value of the acoustic parameter according to the downloaded acoustic data. The user actually listens to the sound and confirms whether or not the user's preference is met.

  Of course, it is also possible to correct the acoustic parameters for the downloaded acoustic setting information of others. When the information of the corrected acoustic data may be shared, the information may be uploaded and registered in the information center as described with reference to FIGS.

  In FIG. 7B, the search is performed using the vehicle information as a key. Alternatively, the acoustic data may be searched using “device information” or “user characteristics” as a key. Further, a search may be performed by combining conditions such as vehicle information and device information or vehicle information and user characteristics.

  As described above with reference to FIG. 5 to FIG. 7, the acoustic setting data in which the characteristics of the vehicle and the devices mounted on the vehicle, the user's music preferences, and the like are registered as a profile are used. Thus, it becomes easy to understand how a person who likes what kind of music in what kind of vehicle sets the sound field environment. By using this information and automatically adjusting the acoustic parameters based on the acoustic setting data, there is no need to manually set up a complicated sound field environment, and the optimal sound field environment can be easily realized for the user. It becomes possible to do.

  In addition, by correcting the acoustic parameters based on the registered acoustic setting data and registering them as new acoustic data in the information center 50, the accumulated acoustic data increases, thereby expanding the selection range of the acoustic data. The possibility of providing an ideal sound field environment for the user is increased.

  In the above description, the acoustic information registered in the information center 50 is downloaded to the in-vehicle acoustic device 40, matched with the user's profile information on the in-vehicle acoustic device 40 side, and the acoustic setting data is searched. However, the sound setting data may be searched on the information center 50 side, and the sound setting data approximate to the user's profile information may be provided to the in-vehicle sound device 40. 8 and 9 are flowcharts showing an example of the processing. FIG. 8 is a flowchart of processing performed by the audio control unit 15 and the in-vehicle server control unit 31 of the in-vehicle acoustic device 40, and FIG. 9 is a flowchart of processing performed by the server control unit 52 of the information center 50. 8 and 9, the server storage unit 53 of the information center 50 stores a plurality of vehicle interior acoustic information, and the vehicle's memory stores the vehicle interior acoustics of the vehicle. Assume that information is stored.

  In the next step S32, acoustic data of the host vehicle (referred to as vehicle A) is transmitted to the information center 50. The acoustic data includes profile information in which the vehicle type of the vehicle A, the user's music preference, and the like are defined, and acoustic setting data for determining the value of the acoustic parameter.

  9, when the information center 50 receives the acoustic data from the vehicle A, the received acoustic data is compared with the plurality of acoustic data stored in the server storage unit 53 in the next step S42. Similar to step S24 of FIG. 5, this comparison is performed to determine whether or not the profile data of the acoustic data of the vehicle A and the profile data of the acoustic data stored in the server storage unit 53 are matched for each element. The overall matching rate is calculated.

  In the next step S43, a list of user names is created in descending order of matching rate and transmitted to the vehicle A.

  Next, in step S33 of FIG. 8, a list of user names sorted in descending order of the matching rate transmitted from the information center is received and displayed on the screen of the display device 22 as shown in FIG. 6B.

  In the next step S34, it is determined whether or not the user has selected a user name. The determination of whether or not there has been a selection is the same as step S26 in FIG. If there is a selection, the process proceeds to step S235.

  In the next step S35, the selected user name is transmitted to the information center 50.

  When the information center 50 receives the selected user name from the vehicle A in step S44 of FIG. 9, the acoustic data of the user name is extracted from the server storage unit 53 and transmitted to the vehicle A in the next step S45. .

  Next, in step S36 of FIG. 8, the in-vehicle acoustic device 30 receives the acoustic setting data transmitted from the information center 50, and in the next step S37, sets the value of the acoustic parameter according to the received acoustic setting data.
