FIG. 3 is a circuit diagram showing the entire control system including the scent generator 2.

The control unit 45 receives an ON signal from an ignition switch 46 and an ON signal from a switch 49 of the scent generator. The control unit 45 includes an infrared sensor 33,

24 drive devices 31 and 32, fan 42 motor 42
(A) operates in response to a signal from the control unit 45.

The control unit 45 includes an ignition switch 46 and a switch 4 of the scent generator.
When the driver turns on the audio 48 while the switch 9 is ON, first, as shown in the control block diagram of FIG. 4, a voice state such as a voice tempo is detected based on the voice data (step). A). Next, based on the detected voice state, the type of voice, such as whether the voice is music having an awakening effect or music having a relaxing effect, is determined (step B). Then, a signal corresponding to the determined type of voice is output to the scent generating device 2 (step C), and the scent generating device 2 selectively generates a scent corresponding to the output signal (step D). ).

Next, details of the control of the control unit 45 will be described with reference to the flowchart shown in FIG.

First, in step 1, it is determined whether or not the ignition switch 46 is ON. If it is ON, the process proceeds to step 3 to determine whether or not the switch 49 of the scent generator is ON. If it is determined in step 3 that the switch 49 of the scent generating device is ON, the process proceeds to step 4 and determines whether the switch of the audio 48 is ON.
If it is determined in step 4 that the switch of the audio 48 is ON, the process proceeds to step 5. If NO is determined in step 1, 3 or 4, the process proceeds to step 2 and the door 2 of the scent generators 22 and 24
9, 9 and 30 are closed, the drive of the fan 42 is stopped, and the process returns to the determination of step 1. In step 5, voice data from the audio 48 is subjected to autocorrelation analysis, and pitch information and voice power information are extracted. Next, the process proceeds to step 6, where the audio data is segmented using the audio power information extracted in step 5. Then step 7
Then, based on the result of the segmentation in step 6, the tempo is determined by dividing 60 seconds by the reference length converted into the time length. Then, the process proceeds to step 8, and it is determined whether or not the tempo determined in step 7 is 60 or more, which is a normal tempo for walking. If it is determined in step 8 that the tempo is 60 or more, that is, if it is determined that the music is of an uptempo awakening type, step 1
In step 1, the drive unit 32 of the scent generation unit 24 is driven to close the door 30, while the drive unit 31 of the scent generation unit 22 containing the awakening fragrance 37 (b) is driven to open the door 29.
Is opened, and the routine proceeds to step 12, where the motor 42 (a) of the fan 42 is driven to generate fragrance, and the determination from step 1 is repeated. If it is determined in step 8 that the tempo is 60 or less, that is, if it is determined that the music is a slow tempo relaxing music, the process proceeds to step 9 where the driving device 31 of the scent generating unit 22 is driven to open the door. 29
While the door is opened by driving the driving device 32 that opens and closes the door 30 of the scent generator 24 containing the relaxing fragrance 38 (b), and proceeds to step 10 to move the motor 42 (a) of the fan 42. ) To generate fragrance,
It returns to the judgment of step 1.

The processing executed in steps 5 to 7 is, for example, the processing disclosed in Japanese Patent Application Laid-Open No. 64-21498 or a similar known processing.

As described above, the first embodiment focuses on the fact that when drowsiness is felt, music with an awakening effect is played, and the played music is analyzed to determine whether the music is awake or relaxed. In order to generate an arousal-type scent with an awakening effect when it is determined to be an arousal-type music, and to generate a relaxed-type scent with a relaxing effect when it is determined to be a relaxed type, for example, When the driver feels drowsiness and plays music, for example, a scent having an awakening effect can be generated accurately, and the drowsiness of the driver can be eliminated.

Also, when the control unit 45 analyzes the music played by the driver and determines that the driver plays relaxed music, that is, when the driver wants to relax and drive, there is a relaxing effect. Since the scent is generated, the driver can enjoy the drive in a more relaxed state.

In the first embodiment described above, when the ON signal of the ignition switch 46, the ON signal of the switch 49 of the scent generator, and the audio data from the audio 48 are input, the control unit 45 outputs the audio data. We start an autocorrelation analysis, but on the other hand,
The control unit 45 is configured to detect the residue of the fragrance according to the procedure shown in FIG. 6 and keep the intensity of the generated scent constant.

That is, the signal from the ignition switch 46 is ON in step 21 of FIG. 6, the signal from the switch 49 of the scent generator is also ON in step 22, and the audio 48 in step 23.
Switch is also ON, and it is determined that audio data from the audio 48 has been input to the control unit 45. Next, the routine proceeds to step 24, where the vehicle speed at which a signal is issued when detecting that the vehicle speed is 0 km / h is detected. Sensor 47
It is determined whether there is a signal from. If it is determined in step 24 that there is a signal from the vehicle speed sensor 47, the process proceeds to the next step 25, and it is determined whether there are no two signals from the infrared sensors 33 and 34. If NO is determined in the steps 21 to 24, the process returns to the step 21 and the determinations in the steps 21 to 24 are repeated. In step 25, there are no two signals from the infrared sensors 33, 34,
If both light from the infrared sensors 33 and 34 are blocked by the light-shielding plate 35 because the amount of the fragrance is sufficient, the process proceeds to step 26 and the heating wires 37 (a) and 38
The determination up to step 25 is repeated without energizing (a). In step 25, the infrared sensors 33, 34
If there are no two signals from the infrared sensor 33, the process proceeds to the next step 27, where it is determined whether or not there is only a signal from the infrared sensor 33. In step 27, there is only one signal from the infrared sensor 33, that is, since the fragrance is slightly reduced and lightened, the light shielding plate 35 is slightly raised by the reaction force of the spring 41, and only the infrared sensor 34 is Blocked by the other infrared sensor 33
When only the light from the light receiving portion 33 (b) is received by the light receiving portion 33 (b) through the narrow portion of the opening 35 (c) of the light shielding plate 35, the process proceeds to the next step 28 and the heating wire 37 (a) , 38
(A) is energized for 30 seconds. After energizing for 30 seconds in step 28, return to step 21 and execute step 2
Repeat the judgment from 1. If there is not one signal from the infrared sensors 33 and 34 in step 27, that is, since the fragrance is considerably reduced and the weight is very light, the light shielding plate 35 rises considerably by the reaction force of the spring 41, When both of the light from the infrared sensors 33 and 34 are not blocked by the light shielding plate 35 and are received by the light receiving portions 33 (b) and 34 (b) through the wide portion of the opening 35 (c). Proceeds to the next step 29, where the heating wires 37 (a), 3
8 (a) is energized for 1 minute. After energizing for one minute in step 29, the process returns to step 21 and the determination from step 21 is repeated.

That is, when the ignition switch 46 and the switch 49 of the scent generator 2 are ON and there is audio data from the audio 48, the control unit 45 checks the remaining amount of the fragrance every time the vehicle stops. Heating wires 37 (a), 38 according to the remaining amount of fragrance
(A) is appropriately energized to heat the fragrance and an instruction is given to change the degree of vaporization of the fragrance, so that the fragrance of the fragrance can always be maintained at a constant intensity.

In the processing from step 27 to step 29, step 9 in the flowchart of FIG.
When the process of step 10 is being executed, the heating wire 3
8 (a), only step 1 in the flowchart of FIG.
1. When the processing of step 12 is being performed, it is also possible to configure so that only the heating wire 37 (a) is energized.

In step 24, the vehicle speed is 0 km
Although it is configured to proceed to step 25 when / h, it is also possible to configure to proceed to step 25 every fixed time, for example, every 30 minutes.

Next, a second embodiment will be described with reference to FIGS. The second embodiment is directed to an apparatus that determines the type of sound and generates a different scent according to the type of sound.
The amount of fragrance generated is increased or decreased according to the volume.

The parts substantially the same as those of the first embodiment are denoted by the same reference numerals as those used in the first embodiment, and the detailed description is omitted.

As shown in FIG. 7, in addition to the ON signal from the ignition switch 46, the ON signal from the switch 49 of the scent generator, the audio data from the audio 48, and the volume of the audio 48, A signal is input from a volume sensor 50 for detecting whether is increased or decreased.

The volume sensor 50 is set so that the volume of the audio 48 increases when the volume knob is turned clockwise and decreases when the volume knob is turned counterclockwise. It is configured to detect whether the position has been moved to the right or to the right.

The operation of the second embodiment having the above configuration will be described below.

FIG. 8 is a flowchart showing the control by the control unit 45 from when the driver turns on the ignition switch 46 to when the scent generator 2 generates the scent. Steps 1 to 12 in this flowchart are basically the same as those in the first embodiment.

When the driver turns on the audio 48 while the ON signal from the ignition switch 46 and the ON signal from the switch 49 of the scent generator are input to the control unit 45, the sound from the audio 48 is output. The data is input to the control unit 45 (steps 1 to 4). The control unit 45 to which the audio data has been input performs an autocorrelation analysis on the audio data and then segments, and determines the audio tempo based on the result (steps 5 to 7). Then, based on the determined tempo, it is determined whether the music is relaxed or aroused, and the scent generator 22 or the scent generator 2 is determined.
Then, the doors 29 or 30 are opened by driving the drive devices 31 and 32 of No. 4 and the motor 42 (a) of the fan 42 is driven to generate fragrance (steps 8 to 12). When the fan 42 is driven in step 10 or step 12, the process proceeds to the next step 13, where it is determined whether or not the sliding terminal of the volume has moved. If it is determined in step 13 that it has moved, the process proceeds to step 14 and it is determined whether or not it has moved to the right. If it is determined in step 13 that the sliding terminal has not moved, the process returns to step 1. If it is determined in step 14 that it has moved to the right,
Proceeding to step 16, the motor 4 for driving the fan 42
The amount of power to 2 (a) is increased to increase the amount of air flow, and the process returns to step 1. If it is determined in step S14 that the sliding terminal has not moved to the right, the process proceeds to step S15, in which the amount of electricity to the motor 42 (a) for driving the fan 42 is reduced to reduce the amount of air blow, Then, the process returns to the determination of step 1.

Here, the relationship between the position of the sliding terminal, the amount of air blow, and the amount of fragrance generated is, for example, that when the slide terminal is not moved, the amount of air blow is (medium), and the amount of scent generated at that time is The rear seat occupant also smells slightly (medium), and when the sliding terminal is moved to the left, the air flow is small (small). The setting is such that the driver of the seat smells (small).

It should be noted that the setting of the air flow amount corresponding to the position of the sliding terminal is made finer. For example, as the sliding terminal moves to the left, the air flow amount gradually decreases, and the amount of fragrance generated also increases. It is also possible to set such that the number gradually decreases.

As described above, the second embodiment focuses on raising the volume of music when the drowsiness is still not wiped out by playing music, and generates a scent having an awakening effect by playing awakening music. When the driver raises the volume of the audio 48, such as when the drowsiness has not yet been wiped out, the amount of air blown by the fan 42 is increased, and the amount of generated scent is increased. It is possible to give a stimulus according to the degree of sleepiness of the driver, and it is possible to effectively dispel sleepiness.

Further, since drowsiness is almost wiped out, when the volume is reduced, the amount of air blown by the fan 42 is reduced and the amount of generated scent is also reduced, so that there is no unpleasant feeling of unnecessarily strong scent. .

In the control unit 45 of the first and second embodiments, after the segmentation is performed by using the audio power information by the segmentation means, the tempo is determined based on the result of the segmentation, and the awakening-based music is determined from the tempo. After the segmentation, the pitch was identified using the pitch information in each segment obtained as a result of the segmentation, and the pitch obtained as a result of the pitch identification was obtained. It is also possible to determine the key on the basis of the key and to determine whether the music is awake or relaxed based on the combination of the key and the tempo.

In the first and second embodiments, the control unit 45 determines whether the music is of the awake type or the music of the relax type, and emits a signal corresponding to the music.
Receives the signal and generates a scent of either an awakening type or a relaxing type. However, the scent generating device 2 has an operation mode for generating a scent and a stop mode for not generating a scent. One of the two modes may be selected according to the output signal. For example, the control unit 45 determines whether the music is awakening music or other music based on the tempo, and issues a signal corresponding to the music. The scent generator 2 only emits a scent when receiving a signal indicating that the music is awakening music. Can be generated, and the operation can be stopped when a signal indicating that the music is another music is received.

The control unit 45 is provided with a volume sensor for detecting not only the tempo but also a volume value, and emits a signal based only on the detected volume value, or emits a signal based on both the tempo and the volume value. It is also possible to select the mode of the scent generator 2.

As described above, by providing the operation mode and the stop mode in the scent generating device 2, the scent is generated only when a certain amount of music is played instead of constantly generating some scent. Therefore, the driver can be more effectively stimulated.

In the first and second embodiments, the control unit 45 discriminates between awakening music and relaxing music based on the tempo. However, a volume sensor for detecting a volume value is provided. The determination may be made based on the volume value detected by the sensor or based on both the volume value and the tempo.

Further, the control unit 45 does not judge whether the system is awake or relaxed, and outputs a signal corresponding to the detected volume value and tempo, and both the volume value and the tempo to the scent generating device 2. It is also possible to generate a scent corresponding to the output signal among a plurality of scents.

As described above, the configuration in which a plurality of different scents are generated according to the tempo and the volume value makes it possible, for example, to feel drowsy when playing music at a slow tempo and to adjust the volume to a certain value. When the volume is increased as above, a scent or the like having an awakening action corresponding to the volume value is generated.Also, when the volume is reduced due to awakening of drowsiness, a scent or the like corresponding to the reduced volume value is generated, so that the driver's odor is further increased. It is possible to generate a fragrance suitable for the physical and mental conditions, and to maintain the physical and mental condition of the driver in good condition.

In the second embodiment, an increase or decrease in volume is detected and the amount of fragrance generated is increased or decreased accordingly. Instead of the volume sensor 50, a volume sensor for detecting the value of the volume is provided. An output signal corresponding to the volume value detected by the sensor or the tempo detected by the control unit 45, the volume value, and the value of the tempo is output to the scent generating device 2 so that the amount of scent generated varies according to the numerical value. It is also possible.

As described above, by varying the amount of generation of the scent according to the tempo and the volume value, it is possible to generate a more appropriate amount of the scent more suited to the music.
For example, even when the volume is set large before the audio 48 is turned on, a large amount of scent can be generated from the beginning.

For example, when music is played in which the tempo mixed with the up tempo and the slow tempo is not uniform, the amount of fragrance generated in the up tempo portion increases, and the amount generated in the slow tempo portion decreases. Since the amount of fragrance generation is adjusted according to the music tempo, the effect of the music on the mental and physical condition of the driver can be enhanced.

In the first and second embodiments, the scent generator 2 drives the fan 42 of the blower 23 to generate the scent. For example, when the air conditioner 1 is activated, air flows into the duct 19. When the air is flowing, the air in the air blower 23 is sucked into the duct 19 and a scent is generated in the vehicle interior. Therefore, it is possible to prevent the fan 42 from being driven when the air conditioner 1 is operating. is there.

It is also possible to omit the fan 42 of the scent generating device 2 and to make the scent generating device 2 generate a scent directly in the vehicle interior.

As described above, the present invention is not limited to the above-described embodiment, and various modifications can be made. As a means for determining the type of sound flowing from the audio 48 in the control unit 45, a volume And a means for discriminating the type of voice based on at least one of the tempo and the tempo.
