[0032]
[2. Action)
The present embodiment configured as described above operates as follows.
[2-1. (Overall effect)
The navigation control unit 81 is a navigation means for performing navigation. The navigation uses the road map data to sequentially detect the position of the vehicle by GPS or the like and display it on a surrounding map, or to a specified destination. The optimum guidance route is searched and the direction of travel is guided and guided along the screen display or synthesized voice. The audio control unit 82 is a music playback means, and plays back music using an amplifier, a speaker system, etc. (not shown).
[0033]
Further, the correspondence recording unit 83 rewrites the route information representing the route set in the navigation control unit 81 and the music information representing the music selected while traveling on the route and reproduced by the audio control unit 82 in association with each other. It records in the possible storage medium device 6. The selection processing unit 84 is a part that performs music data selection processing (hereinafter referred to as “music selection”) in accordance with a user operation.
[0034]
[2-2. (Mode of music selection)
As a mode of selection of music by the selection processing unit 84, that is, a method (method), in addition to several types common to the related art, ones specific to the present invention and this embodiment can be selected. That is, first, data stored in a large amount by a user in an HDD or the like generally has a hierarchical structure. When searching for target data from these data, for example, when searching for target music data from a large amount of music data existing in the HDD,
(1) A mode in which a list of data is displayed on a display and the user selects one from the list (referred to as “direct search”),
(2) A mode in which a search is performed based on the name of a song or a keyword associated in advance by a user, and the song data is narrowed down from all the song data and presented to the user (referred to as “keyword search”). )
(3) The date and time when the music was saved in the HDD and the date and time when it was played are recorded in the database for each music, and the music data is narrowed down and presented from all the music data based on the date and time, and the user is given the result. How to select (referred to as “time search”),
(4) A method of recording the frequency of reproduction and other statistical information in a database for each song, sorting them in this frequency order and presenting them to the user (referred to as “statistical search”),
and so on.
[0035]
Further, two or more of these methods can be used in combination, but in the present embodiment, in addition to these search methods, the following search methods can be newly selected. That is, when there is a request for music information search, the selection processing unit 84 presents each route of each route information recorded in the rewritable storage medium device 6, accepts the selection, and selects the selected route. Each music piece corresponding to each music piece is presented and its selection is accepted.
[0036]
[2-3. (Recording route information and music information)
Here, FIG. 2 shows an example of a processing procedure related to music selection in the present embodiment. For example, when the user sets the destination as “B point” at the navigation control unit 81 at the departure point “A point” (step 1), the route from the departure point to the destination is determined by some method such as bidirectional search. Calculated (step 2). In addition, the guidance based on the route calculated in this way is the same as in the past, for example, a map of the periphery around the vehicle position detected by using various position detection devices is displayed on the display, The route in the map is displayed in a special color.
[0037]
As described above, the user goes to the destination with reference to the route guide presented by the navigation control unit 81, that is, the guidance guidance. At this time, for example, in the destination route information database 10 illustrated in FIG. "When moving from point to point B" is recorded (step 3). Then, while driving to the destination, the user wants to listen to music, and the selection processing unit 84 is used to search for a certain song “MMM” from the presented list using some search technique and play the song. Then (step 11), the correspondence recording unit 83 associates the information “when moving from point A to point B” for the music “MMM” and records it in the destination route information database 10 (step 12).
[0038]
By the way, when searching for music, it is assumed that the user calls “music search” from a function display option by an operation, and FIG. 4 shows an example of the transition from there. In other words, in the search method display that follows “Song Search”, “List Display”… (direct search)
“Recently heard songs”… (time search)
“List by date”… (Same as above)
“Frequently listened songs”… (statistical search)
"Song title search" ... (Search by keyword using song title)
"Keyword search" ... (Keyword search)
In addition to the conventional options such as “currently moving song list” newly proposed in the present invention and this embodiment
Is displayed, which will be described later.
[0039]
From these displayed search methods, the user selects a desired one using the input unit 11. Here, for example, if the user selects the conventional “keyword search” (step 4), then the contents prompting the user to input a keyword are displayed on the display, and all music data having the input keyword is presented. (Step 5). Further, it is possible to further narrow down the presented music data by using a composite condition, that is, a plurality of search methods, by adding a search condition (steps 9 and 10).
[0040]
Similarly, if the selection processing unit 84 selects and plays the music “NNN”, “LLL”... (Step 11), the correspondence recording unit 83 also sets “A” for the music “NNN” and “LLL”. The route information “point to point B” is associated and recorded in the destination route information database 10 (step 12). In the case of reproducing music, the data to be selected may be a playlist that describes the reproduction order. FIG. 3 shows an example of entries (contents) in the destination route information database 10 in which information is recorded in this way.
[0041]
[2-4. (Selection by moving song list)
If the user sets a route such as “C point to D point” at a later date, the route is calculated by the navigation control unit 81, and a route guide, that is, guidance guidance is presented by screen display or voice synthesis. The user goes to the destination with reference to the route guide presented in this way. Suppose that the user wants to listen to a song, recalls that the song was heard while moving from "A point to B point" the other day, and called the "song search" function described above. .
[0042]
Following “song search”, as shown in FIG. 4, in addition to “list display”, “recently listened songs”, “list by date”, “listen songs”, “song name search”, “keyword search”, The item “moving song list” is displayed on the display. When this “moving song list” is selected by the input unit 11 (step 4), the selection processing unit 84 refers to the position route information database 10 and the route. An information list is presented (step 6). That is, “When moving from point A to point B”, “When moving from point X to point Y”, “When driving on the fresh green drive course”, etc. Are displayed on the display in this order.
[0043]
When the input unit 11 selects, for example, an item “when moving from point A to point B” from the presented route information list (step 7), the selection processing unit 84 stores the destination route information database 10 in the destination route information list. By referencing, a list of music data such as music data “MMM”, “NNN”, “LLL”,... Associated with the route information “from point A to point B” is displayed on the display (step 8).
[0044]
In this way, in this embodiment, it is possible to newly narrow down the target music from a large amount of music data by specifying where the music is heard when going out. The search based on the place “Where did you hear when you went?” Is easier than the search based on the time.
[0045]
[3. effect〕
As described above, in this embodiment, route information such as a destination and a route set by navigation and a song heard at that time are automatically associated with each other and stored in a storage unit such as a hard disk device. A simple operation that allows the user to specify where to go and where to listen, and realizes excellent operability that can efficiently search for songs, such as narrowing down the desired songs from a large number of songs. The
[0046]
[4. Other embodiments]
In addition, this invention is not limited to the said embodiment, Other embodiments which are illustrated next are included. For example, in the above embodiment, the route information is associated with the music data reproduced by the route. However, when recording a song from a CD or the like and recording it on the HDD, the condition such as “I want to listen to this route” is used. The route information may be associated with the music data. The rewritable storage means is not limited to a hard disk drive, and can be replaced with a drive such as a DVD-RAM, DVD-RW, or CD-RW, or various flash memory cards.
[0047]
In addition to music data, the display pattern illumination pattern data, sound quality and balance data adjusted by graphic equalizers and other switches, and engine and suspension controls that determine the driving mode are the targets to be associated with the route information. Various data such as data may be recorded in association with the route so that it can be easily recalled later.
