- the alarm information includes specific contents of the alarm or a flag corresponding to the contents.
- the alarm level indicates the urgency or importance of the alarm. That is, the alarm level is divided according to the degree of urgency or importance according to the content of the alarm, and the alarm level increases as the degree of urgency or importance increases. For example, the alarm level is divided into three levels: a first alarm level indicating warning, a second alarm level indicating alerting, and a third alarm level indicating notification. In the ECU 2, the content of the alarm and the alarm level are associated with each other.
- Speaker 3 is a device that outputs sound.
- the speakers 3 are provided on the left and right sides of the driver's seat, for example.
- the alarm generation processing device 10 generates an alarm sound from the speaker 3 based on the alarm generation instruction transmitted from the ECU 2.
- the alarm generation processing device 10 is configured by, for example, a microcomputer embedded in a meter panel (not shown).
- the alarm generation processing device 10 functionally includes an alarm acquisition unit 11 and an alarm generation unit 12.
- the alarm acquisition unit 11 acquires the alarm level of the alarm to be generated. That is, the alarm acquisition unit 11 is connected to the ECU 2 via a communication circuit such as CAN communication, and acquires the alarm level of the alarm to be generated from the alarm generation instruction transmitted from the ECU 2.
- the alarm generation unit 12 generates an alarm sound corresponding to the alarm level acquired by the alarm acquisition unit 11.
- a storage device 13 in which various alarm sounds to be generated are recorded is connected to the alarm generation unit 12. Examples of the storage device 13 include a ROM and a hard disk.
- the alarm sound stored in the storage device 13 is composed of a plurality of sounds having a width of 200 Hz or more. As shown in FIG. 2, it becomes difficult for a person to hear sound with aging. In particular, when the frequency exceeds 200 Hz, difficulty in hearing with aging becomes remarkable. Therefore, the warning sound is composed of a plurality of sounds having a width of 200 Hz or more so that the warning sound includes a sound in a frequency range that can be heard even by a driver whose sound has become difficult to hear due to aging. In this case, the alarm sound may be composed of a plurality of sounds having a width of 1000 Hz or more. The number of sounds constituting the alarm sound is not particularly limited as long as it is plural. Among a plurality of sounds constituting the alarm sound, the difference between the frequency of the sound with the lowest frequency and the frequency of the sound with the highest frequency is 200 Hz or more.
- the alarm sound stored in the storage device 13 is divided into alarm levels, and the chord and rhythm of the alarm sound differ depending on the alarm level.
- the alarm sound is stored in association with the alarm level.
- an alarm sound with an alarm level equal to or higher than a reference level is composed of a dissonance, and an alarm sound with an alarm level less than the reference level is composed of a consonance.
- an alarm sound with an alarm level equal to or higher than a reference level is configured with a rhythm with a short intermittent interval compared to an alarm sound with an alarm level less than the reference level.
- the alarm sound may be configured with a rhythm with a short intermittent interval as the alarm level increases.
- an alarm sound with an alarm level equal to or higher than a reference level is configured with an irregular rhythm
- an alarm sound with an alarm level less than the reference level is configured with a regular rhythm.
- the reference level is one of a plurality of alarm levels, and can be set as appropriate.
- the reference level may be the first alarm level.
- a third alarm level FIG. 4A shows an example of the chord and rhythm of the alarm sound at the first alarm level
- FIG. 4B shows an example of the chord and rhythm of the alarm sound at the second alarm level
- FIG. 4C shows an example of the chord and rhythm of the alarm sound at the third alarm level.
- the higher the alarm level the higher the frequency range of a plurality of sounds constituting the alarm sound.
- the alarm sound at the second alarm level has a higher frequency range than the alarm sound at the third alarm level, and the alarm sound at the first alarm level is higher than the alarm sound at the second alarm level. Also raise the frequency range.
- the frequency of each sound constituting the alarm sound of each alarm level is preferably in the range of 1000 Hz to 3000 Hz.
- the alarm generation unit 12 acquires an alarm sound corresponding to the alarm level acquired by the alarm acquisition unit 11 from the storage device 13, and generates the acquired alarm sound. That is, the alarm generation unit 12 varies the chord and rhythm of the alarm sound to be generated according to the alarm level acquired by the alarm acquisition unit 11. For example, when the alarm level acquired by the alarm acquisition unit 11 is equal to or higher than the reference level, the alarm generation unit 12 generates a dissonant alarm sound, and when the alarm level acquired by the alarm acquisition unit 11 is less than the reference level, Generate a harmonious warning sound.
- the alarm generation unit 12 is configured such that when the alarm level acquired by the alarm acquisition unit 11 is equal to or higher than the reference level, a rhythm alarm with a shorter intermittent interval than when the alarm level acquired by the alarm acquisition unit 11 is less than the reference level.

- the alarm generation unit 12 generates an irregular rhythm alarm sound when the alarm level acquired by the alarm acquisition unit 11 is equal to or higher than the reference level, and the alarm level acquired by the alarm acquisition unit 11 is less than the reference level. If you want to generate a regular rhythm alarm sound.
- the alarm sound is generated by, for example, blowing the speaker 3.
- the storage device 13 may store one type of alarm sound for each alarm level, or may store a plurality of types of alarm sounds corresponding to the type of alarm for each alarm level. When a plurality of types of alarm sounds corresponding to the alarm types are stored in the storage device 13, the storage device 13 acquires the alarm sounds corresponding to the alarm types acquired by the alarm acquisition unit 11 from the storage device 13. The acquired alarm sound may be generated.
- the alarm sound is composed of a plurality of sounds having a width of 200 Hz or more, even a driver whose sound has become difficult to hear due to aging. Sounds in the audible frequency range can be included. Furthermore, since the warning sound is composed of a plurality of sounds, the sound pressure difference at each position in the passenger compartment is reduced. Thereby, an alarm sound can be heard by the driver at a target sound pressure or a sound pressure close to the target sound pressure. Moreover, since the chord and rhythm of the alarm sound differ depending on the alarm level, the driver can understand the alarm level of the alarm sound even if the alarm sound heard is small. As a result, the driver can easily hear the alarm sound.
- the alarm level is higher than the reference level, generating a dissonant alarm sound can give the driver a serious feeling, and if the alarm level is lower than the reference level, a consonant alarm sound is generated. This can give the driver a sense of security. Thereby, it is possible to make the driver understand the alarm level of the alarm sound sensuously.
- the alarm level is equal to or higher than the reference level, it is possible to give the driver a sense of urgency by generating an alarm sound with a rhythm with a shorter intermittent interval than when the alarm level is less than the reference level. Thereby, it is possible to make the driver understand the alarm level of the alarm sound sensuously.
- the alarm level when the alarm level is higher than the reference level, it is possible to give the driver a sense of security by generating an irregular rhythm alarm sound. On the other hand, when the alarm level is lower than the reference level, it is possible to give a serious feeling to the driver by generating a periodic rhythm alarm sound. Thereby, it is possible to make the driver understand the alarm level of the alarm sound sensuously.
