When it is determined by the judging means that the driving support device is in the non-operating state, the generation of the fluctuation sound by the fluctuation sound generating device is prohibited and the detection result of the driving state detecting means is acquired and the vehicle is running. Is detected by the determination means, or when the detection result of the driving state detection means is acquired and it is detected that the vehicle is parked, the fluctuation sound generator You may make it generate a fluctuation sound. In other words, fluctuation noise is prohibited during driving when the driving assistance device is not operating, so that the relaxation effect on the driver is suppressed and safety can be improved. In addition, a fluctuation noise is generated during driving or parking when the driving assistance device is operating, so the driver can relax. Alternatively, in claim 10, as in the invention described in claim 12, the adjustment unit detects that the vehicle is traveling by obtaining the detection result of the traveling state detection unit, and supports driving by the determination means. When it is determined that the device is in a non-operating state, the aroma generating device generates awakening fragrance, acquires the detection result of the traveling state detection means, and detects that the vehicle is traveling. When it is determined that the vehicle is in an operating state, the fragrance generating device generates sedative fragrance, and the detection result of the running state detecting means is acquired to detect that the vehicle is parked. You may make it generate a hypnotic fragrance. That is, since the awakening fragrance is generated while the driving support device is not operating, the driver can be awakened and the safety can be improved. In addition, sedative fragrance is generated while the driving support device is operating, so the driver can be relaxed and the driver can be relaxed while ensuring safety. In addition, since a scenting scent is generated while parking, it is possible to seduce during safe parking and the driver can take a nap.

Alternatively, in claim 10, as in the invention described in claim 13, the adjusting means acquires the detection result of the running state detecting means and is detected to be running, and driving assistance is provided by the judging means. When it is determined that the device is in the non-operating state, the decoration color is changed so that the decoration color changing device gives a wakeful effect, and the detection result of the driving state detection means is acquired and the vehicle is running. If it is determined by the determination means that the driving support device is in an operating state, or if the detection result of the traveling state detection means is acquired and it is detected that the vehicle is parked, You may make it change a decoration color so that it may become a color which gives a calming effect by a color change apparatus. In other words, the decoration color is changed so that the color gives an awakening effect while the driving support device is not operating, so that the driver can be awakened and safety can be improved. In addition, the decoration color is changed to give a sedative effect while driving or parking while the driving assistance device is operating, so the driver can be relaxed while ensuring safety.

As described above, according to the present invention, the driving environment is adjusted so that the driver's mental state is in accordance with the determination result of the operating state of the driving support device that performs driving support for the driver. Therefore, the driver's mental state suitable for the operating state of the driving support device can be given to the driver by the awakening effect corresponding to the operating state of the driving support device by the adjusted environment.

Further, the air conditioning controller 16 is capable of controlling the air flow so as to generate a 1-degree fluctuating wind by controlling the blower motor and the like when adjusting the temperature in the passenger compartment. The 1 / f fluctuation is a fluctuation of the power spectrum that shows fluctuations varying at various speeds, how much the components change slowly, and how much the components change quickly. A “fluctuation” in which the frequency and power appear on an inversely proportional line and the square of each component amplitude is proportional to 1 / f is called 1 Z f fluctuation.

The audio controller 18 stores music including sounds having a plurality of l Z f actions, and selects and outputs a plurality of stored sounds according to instructions of the mental state adjustment controller 12. Yes. The plurality of sounds stored in the audio controller 18 are stored with different frequency and power slopes that are inversely proportional to each other when the power spectrum analysis described above is performed. 1 / f fluctuation music with a slope of average _0.6 (for example, about 10.5 to 10.7), average — 0 8 (for example, about −0.7 to about 0.9) 1 f fluctuation music and 1 Z f fluctuation music having a 1 slope are stored.

The display controller 20 stores a plurality of patterns and images, and controls a display device such as a liquid crystal monitor to display a decorative pattern and a decorative image. Multiple patterns and images stored in the display controller 2 0 give 1 / f fluctuation effect Multiple images and patterns are stored, and images and patterns based on different colors are stored to adjust the mental state of the driver. The basic color of the image or pattern is, for example, the awakening effect by increasing the heart rate or improving the secretion of adrenaline due to the effect of red by setting the color of the basic color of the image or pattern to red. By using yellow, the effect of yellow can promote the concentration of a short period of time, etc. By making green, the effect of green can reduce the nervous system sedation and tension Relief, sleep action, stress reduction, etc. By blue, the effect of blue gives the sedation and stability of the mind, the ability to concentrate, sleep effect, etc., purple By doing so, a hypnotic effect, blood pressure and a pulse-lowering effect can be obtained by the effect of purple. In addition, when other colors are used as the base tone, the effect of the colors can be obtained. The image or pattern stored in the display controller 20 may be an image or pattern that uses a psychological effect of the color, such as a combination of colors or a pattern. It is possible to adjust.

The lighting controller 2 2 adjusts the color of the illumination of the combination meter and illumination lighting. In this embodiment, red, blue, and green LEDs are used as the light source, and multiple lighting colors are used. The color of the lighting is adjusted to adjust the driver's mental state. That is, for example, as described above, the lighting controller 22 can adjust the driver's mental state by adjusting the color in consideration of the psychological effect of each color.

By the way, in this embodiment, as shown in FIG. 2, the driver's mental state is positioned as an uncomfortable-comfort axis and an excitement-sedation axis, and the mental state adjustment controller 12 is arranged in the direction of each axis. The air conditioner controller 16, the audio controller 18, the display controller 20, and the lighting controller 22 are controlled so that the mental state shifts. Specifically, the driving environment that provides four states of awakening in a comfortable and excited direction, a light relaxed state, a relaxed state, and a sufficient relaxed state, which are divided into three comfortable and sedative directions. It is generated by a combination of controller 16, audio controller 18, display controller 20, and lighting controller 22, and adjusts the environment in the passenger compartment. Next, an example of the flow of processing performed by the mental state adjustment controller 12 of the mental state adjustment device 10 configured as described above will be described. FIG. 3 is a flowchart showing an example of the flow of processing performed by the mental state adjustment controller 12 of the mental state adjustment apparatus 10 according to the embodiment of the present invention.

First, in step 100, it is determined whether or not a passenger has boarded. For this determination, for example, a cartesis switch is used as an occupant detection means 26 and is connected to the mental condition controller 12 to detect the opening of the door by the cartis switch or to operate the switch. The process waits until the determination is affirmed and proceeds to step 102.

In steps 1 and 2, the environment is adjusted to give the driver a relaxing effect. For example, the display controller 20 can display images and patterns that have a 1 / f effect, or the audio controller 18 can output music and natural sounds that give a 1 / f effect, as shown in Figure 2. The display controller 20 and the audio controller 18 are controlled so as to be in a relaxed state. As a result, the environment in the passenger compartment can be adjusted and the driver can be relaxed. At this time, the air conditioning controller 18 may generate a fragrance that gives a relaxing effect.

Next, at step 104, it is determined whether or not the vehicle is in operation. The determination is made by determining whether or not the vehicle is traveling from the vehicle speed obtained via the engine ECU 40 and the cruise control ECU 30. If the determination is affirmative, the routine proceeds to step 106. If the result is negative, the process proceeds to step 108.

In steps 10 and 6, the environment is adjusted to give the driver an awakening effect. For example, the air-conditioning controller 16 outputs a fragrance of a component that activates the brain by secreting adrenaline in the brain, such as rosemary and jasmine, which has an awakening effect, and outputs it in a wind of 1 f fluctuation. 1f Fluctuating music and sounds that give the effect of fluctuating by the display controller 20 Displaying images that give a 1 Z f fluctuation effect based on the color to which the adrenaline such as red is secreted by the display controller 20 Then, the lighting controller 2 2 controls the lighting based on the red color to control the light and darkness so that it fluctuates. As a result, the environment in the passenger compartment is shown in Figure 4A. The environment is adjusted to the driver's state and awakens the driver, and the driver can be awakened.

Next, at step 10 8, it is determined whether or not auto-cruising is in progress. This determination is made by acquiring the operation state of the cruise control switch 3 2 via the automatic control control ECU 30 and determining whether or not the state of the cruise control switch 3 2 is the state where the auto cruise is selected. This is done by judging. In step 108, if the determination is affirmative, the process proceeds to step 110, and if the determination is negative, the process proceeds to step 1 12 as it is.

In step 1 1 0, the environment is adjusted to give the driver a light relaxing effect. For example, the air conditioning controller 16 outputs a fragrance of a relaxing ingredient such as sweet marsholum that has a slight sedative effect on the 1 / f fluctuation wind, and the frequency and power when the power spectrum analysis is performed by the audio controller 18 The slope of the line that is inversely proportional to 1 / f outputs music or sound that gives an average 1 / f fluctuation effect, and the display controller 2 0 gives 1 / f fluctuation action based on a calming color such as green. Display an image or pattern, etc., and illuminate the lighting controller 2 2 with clear control so as to produce l Z f fluctuation based on green. As a result, the environment in the passenger compartment is adjusted to the state shown in Fig. 4B, and the driver is lightly calmed down, and the driver can have a light relaxing effect.

Next, in Step 1 1 2 it is determined whether automatic operation is in progress. The determination is made by acquiring the operation state of the cruise control switch 3 2 via the auto cruise control ECU 30 and determining whether or not the state of the cruise control switch 3 2 is the state where the automatic operation is selected. Made by. In step 1 1 2, if the determination is affirmative, the process proceeds to step 1 1 4, and if the determination is negative, the process proceeds to step 1 1 6 as it is.

In steps 1 1 4 the environment is adjusted to give a relaxing effect. For example, the air conditioner controller 16 outputs a scent of a sedative component such as sandalwood on a 1 / f fluctuation wind, and the audio controller 18 uses the power spectrum analysis to reverse the frequency and power. The proportional slope of the straight line outputs music or sound that gives an average 1 / f fluctuation action of 0.8, and the display controller 2 Use o to display a color or pattern that gives a 1 Z f fluctuation effect based on a sedative color such as purple, and use the lighting controller 2 2 to control the light and dark so that the 1 / f fluctuation is based on purple. Illuminate. As a result, the environment in the passenger compartment is adjusted to the state shown in Fig. 4 to create a calming environment for the driver, giving the driver a relaxing effect.

Next, in step 1 1 6, it is determined whether or not the nap environment. The determination is made, for example, by determining whether or not the state of the PKB switch 24 is longer than a predetermined time after the parking brake is applied, and if the determination is affirmative, the step is performed. Move to 1 1 8 and if negative, move to step 1 2 0 as it is. The determination in step 1 16 may be made by connecting a switch such as a nap switch to the mental state adjustment controller 12 2 and determining whether or not the switch has been operated by a passenger.

In steps 1 1 8 the environment is adjusted to give the driver a sufficient relaxing effect. For example, the air-conditioning controller 16 outputs a fragrance with a hypnotic action component such as clary sage in a 1 / f fluctuation wind, and the frequency and power when the power spectrum analysis is performed by the audio controller 18 are inversely proportional. Outputs music or sound that gives an average of 1 Z f fluctuation effect, with the slope of the straight line being 1 1 on average, and gives a 1 f fluctuation effect based on the color of hypnotic action such as blue by the display controller 2 0 Display the pattern or pattern, etc., and illuminate the lighting controller 2 2 with light and dark control based on the blue color and 1 / f fluctuation. As a result, the environment in the passenger compartment is adjusted to the state shown in Fig. 4D, and the driver is brought to an awakening environment, and a sufficient relaxation effect can be given to the driver.

Subsequently, at step 120, it is determined whether or not the environmental adjustment is finished. For example, the determination may be made according to the state of the switch by providing a switch or the like for stopping the control by the mental state adjustment controller 12, and whether or not the idle switch is turned off. You can make a decision.

If the determination in step 1 2 0 is negative, the process is repeated after returning to step 1 0 4, and when the determination in step 1 2 0 is affirmed, the mental state adjustment controller 1 2 The process to be performed is terminated. Thus, when the driver is driving (running), the mental state adjustment controller 1 2 shifts to a state where the driver's mental state is comfortable and aroused in the direction of excitement, as shown in FIG. 4A. As shown in Fig. 4B, the air conditioning controller 1 6, the audio controller 1 8, the display controller 2 0, and the lighting controller 2 2 are controlled so that the environment is comfortable. Control the air conditioner controller 16, audio controller 1 8, display controller 2 0, and lighting controller 2 2 so that the environment is shifted to a light relaxed state with a slight sedation. As shown in Figure 4C, air conditioning controller 1 6, audio controller 1 8, display controller 2 0 Control the lighting controller 2 2. When the control provided for nap is instructed, as shown in Fig. 4D, air conditioning controller 1 6, audio controller 1 so that it becomes a comfortable environment to shift to a sufficiently relaxed state of strong sedation 8. Control display controller 2 0 and lighting controller 2 2. In other words, the driving environment is adjusted so that the driver's mental state according to the driving state and the operating state of the driving support device is adjusted. Therefore, the driving state is set to the driver's mental state corresponding to the operating state of the driving support device. be able to.
