FIGS. 3 (a), 4 (a) and 5 (a) show the contents of various settings displayed on the display unit 101 when the vehicle information providing apparatus 100 is shifted to the customization mode. FIGS. 3B, 4B, and 5B show registration states of various setting contents registered in the customization mode in the second storage unit 204. FIG. In addition, the underline location in each figure of Fig.3 (a), FIG.4 (a), and Fig.5 (a) has shown the initial setting value.

  The user of the vehicle gives an instruction to the control means 202 to operate the customization mode setting terminal 210 from the outside to shift to the customization mode that the control means 202 has in advance. Specifically, the control unit 202 can recognize the terminal by changing the terminal at which the normal potential of the customization mode setting terminal 210 is at “high” level to “low” level by a predetermined operation such as a switch. When the control unit 202 shifts to the customization mode, the control unit 202 executes processing for switching the display unit 101 from the normal display to the initial screen display (initial screen 300) in the customization mode shown in FIG.

  The initial screen 300 is a screen on which the user selects the frequency of each auditory information (sounding frequency by the speaker 243) via the input unit 211. Here, in FIG. 3A, reference numeral 1 denotes a screen for selecting the frequency of the reverse alarm sound that is notified when the user has operated the selector lever of the automatic transmission in the reverse direction. For example, if the user selects the initial setting value from 800 Hz to 700 Hz, the control unit 202 specifies the identification code (identification information) of the user who uses the vehicle via the keyless entry device 220. (Here, ID1 is obtained as the identification code), and the setting contents are stored in the area associated with the identification code ID1 of the second storage means 204. That is, as shown in FIG. 3B, 700 Hz which is the setting content is registered in the frequency 1 area (region R1) corresponding to the identification code ID1. At the same time, the control means 202 performs control so that the underline selected and displayed at 800 Hz on the initial screen 300 is switched to 700 Hz, thereby omitting the illustration, but selecting and displaying 700 Hz instead of 800 Hz. Will do.

  In FIG. 3A, reference numeral 2 denotes a selection screen for the frequency of an alarm sound that is generated based on an alarm instruction from the corner sensor device 224. For example, if the user selects the initial setting value from 4000 Hz to 2000 Hz, the control unit 202 specifies the identification code (identification information) of the user who uses the vehicle via the keyless entry device 220. (Here, ID1 is obtained as the identification code), and the setting contents are stored in the area associated with the identification code ID1 of the second storage means 204. That is, as shown in FIG. 3B, 2000 Hz which is the setting content is registered in the frequency 2 area (region R2) corresponding to the identification code ID1. At the same time, the control unit 202 performs control so that the underline selected and displayed at 4000 Hz on the initial screen 300 is switched to 2000 Hz, thereby omitting the illustration, but selecting and displaying 2000 Hz instead of 4000 Hz. Will do. Here, the initial set value of the frequency of the alarm sound emitted from the corner sensor device 224 is around 4000 Hz, which is a frequency at which the ear sensitivity of adults becomes high and a small sound can be heard well. However, for elderly users, the frequency is high. Since the higher the sound, the more difficult it is to hear, 2000 Hz is selected here.

  In FIG. 3A, reference numeral 3 denotes a selection screen for a frequency of an alarm sound that is generated based on an alarm instruction from the back sonar device 225. Here, since the user has selected the initial setting value of 1000 Hz, the control unit 202 does not write the setting content in the second storage unit 204. As a result, as shown in FIG. 3B, an initial set value of 1000 Hz is stored in the frequency 3 area (region R3) corresponding to the identification code ID1 of the second storage means 204.

  In selecting the frequency of the reverse alarm sound and the alarm sound emitted from the corner sensor device 224 and the back sonar device 225 on the initial screen 300, a preview mark (preview display) 301 provided at the lower right of the initial screen 300 is selected. By selecting, it becomes possible to confirm the frequency of each alarm sound selected in advance in real time. Specifically, when the control unit 202 detects the selection of the preview mark 301, the control unit 202 sounds the frequency of each alarm sound selected by the speaker 243 via the mixing unit 241 and the amplifier 242. The frequency of each alarm sound can be confirmed (recognized) in advance. For example, in the case of a reverse warning sound, the user can confirm in advance the reverse warning sound (frequency) selected (set) by the user before actually operating the select lever in reverse. ing.

  Further, the frequency of the alarm sound (initial setting value) emitted from the corner sensor device 224 and the frequency of the alarm sound (initial setting value) emitted from the back sonar device 225 can be switched according to the user's preference. is there. That is, in this case, the control unit 202 performs back sonar in the region R4 with respect to the frequency 2 area (region R4) and the frequency 3 area (region R5) corresponding to the identification code (here, another identification code ID2). An initial setting value of 1000 Hz, which is the frequency of the alarm sound emitted from the device 225, is written, and a process of writing 4000 Hz, which is the initial setting value of the frequency of the alarm sound, emitted from the corner sensor device 224, to the region R5.

  Next, another initial screen 310 in the customization mode will be described. When shifting to the customization mode, the control unit 202 executes processing for switching the display unit 101 from the normal display to the initial screen display (initial screen 310) in the customization mode shown in FIG. The initial screen 310 is a screen for the user to select via the input means 211 the priority of each auditory information (here, the method for notifying each alarm sound when a plurality of alarm conditions occur simultaneously). is there.

  For example, in FIG. 4A, reference numeral 1 denotes a selection item for sequentially sounding each auditory information (each alarm sound) according to a predetermined priority, and 2 indicates each alarm sound simultaneously generated by the mixing unit 241. The selection items are shown. In the case of 2, it is possible to select whether the sound pressure (sound pressure level) of each alarm sound at that time is the same or whether the sound pressure of each alarm sound is variable according to the priority. Is possible.

  When selecting the priority of each alarm sound on the initial screen 310, each of the items selected in advance in real time by selecting a preview mark (preview display) 311 provided at the lower right of the initial screen 310 is selected. It is possible to check the state of the alarm sound. Specifically, when the control unit 202 detects selection of the preview mark 311, each alarm sound is sequentially sounded or simultaneously sounded for the item selected by the speaker 243 via the mixing unit 241 and the amplifier 242. The user can confirm in advance the sounding state of each alarm sound in the selected item.

  Next, another initial screen 320 in the customization mode will be described. When shifting to the customization mode, the control unit 202 executes processing for switching the display unit 101 from the normal display to the initial screen display (initial screen 320) in the customization mode shown in FIG. Such an initial screen 320 is displayed on the initial screen 320 by the user via the input means 211. The tone of each auditory information (here, the pitch of the alarm sound, whether the alarm sound is sounded as a single tone, a chord is sounded, or the alarm sound is echoed. This is a screen for selecting whether or not to apply.

  Here, in FIG. 5A, reference numeral 1 denotes a selection screen for the tone color of the reverse alarm sound. For example, the initial setting value “single pitch, no sound, no echo” to “pitch length, chord, echo” If the selection is made by the user, the control means 202 specifies an identification code (identification information) of the user who uses the vehicle via the keyless entry device 220 (here, ID1 is used as the identification code). And the setting contents are stored in the area associated with the identification code ID1 of the second storage means 204. That is, as shown in FIG. 5B, the setting content “pitch length, chord, echo” is registered in the timbre 1 area (region R6) corresponding to the identification code ID1. At the same time, the control unit 202 performs control so as to switch each underline selected and displayed on the initial screen 320 to “pitch length, chord, echo”, respectively. As a result, although not shown in the drawing, each underline selectively displays “pitch length, chord, with echo” instead of “in pitch, single note, no echo”.

  Further, in FIG. 5A, reference numeral 2 denotes a selection screen for the tone color of the seat belt non-wearing alarm sound that is notified when the user is not wearing the seat belt. Here, since the user has selected the initial setting value “in the pitch, chords, and echoes”, the control unit 202 does not write the setting contents to the second storage unit 204. As a result, as shown in FIG. 5B, the initial setting value “with pitch, chord, and echo” is stored in the timbre 2 area (region R7) corresponding to the identification code ID1 of the second storage means 204.

  In selecting the tone of the reverse warning sound and the non-seat belt warning sound on the initial screen 320, a preview mark (preview display) 321 provided at the lower right of the initial screen 320 is selected in advance. It is possible to confirm the tone color of each alarm sound selected in real time. Specifically, when the control unit 202 detects the selection of the preview mark 321, the control unit 202 sounds the timbre of each alarm sound selected by the speaker 243 via the mixing unit 241 and the amplifier 242. The tone color of each alarm sound can be confirmed in advance.
