Description

  The present invention relates to an apparatus for adjusting a mind-body state of a passenger who has boarded a moving body such as an automobile, a train, a ship, an airplane, and a spacecraft, and a control method therefor.

In recent years, along with the complex diversification of society, health problems to the human body caused by stress are being raised as social problems. As a technique for alleviating such stress, a technique that applies “1 / f fluctuation” has attracted attention.
“Fluctuation” refers to a slight waveform shift (spatial, temporal change or movement that is partially irregular) that is observed when a wave changes from moment to moment. Is called “1 / f fluctuation”. 1 / f fluctuations are observed not only in the natural waves such as the stream sound of the stream, the wind pressure of the breeze, the shape of the wood grain, and the sound of the chirping of the birds, but also in the waves emitted from the human body (hereinafter referred to as the living body). Is. For example, when the heartbeat interval of the electrocardiogram is examined, the heartbeat interval varies by an average value ± 10% and fluctuations are observed in a state where a healthy person is at rest. If this fluctuation is regarded as a wave and spectrum analysis is performed, 1 / f fluctuation in which the power spectrum is inversely proportional to the frequency f can be observed.

And it has been clarified that listening to music with 1 / f fluctuation gives a healing effect to the body. This is presumed that the rhythm of the living body is in a state of 1 / f fluctuation and that the music synchronized with the biological rhythm feels comfortable. The state of 1 / f fluctuation is slightly different depending on the individual.
On the other hand, various techniques for adjusting the in-vehicle environment according to the mind and body conditions such as sleepiness and stress of the driver of the vehicle have been proposed.

  For example, in Patent Document 1, the driver's tension is estimated as the mind-body state based on the driver's workload and physiological amount (for example, head vibration), and tension that is a preferable reference for the current driving situation. A configuration is disclosed in which the degree is estimated and the driver's tension is relieved or activated according to these degrees. With such a configuration, it is possible to allow the driver to maintain an appropriate feeling of tension and perform the driving smoothly.

  In Patent Document 2, a driver's biological signal (for example, a driver's brain wave, heartbeat, skin potential, etc.) is detected, and an output state of sound information by car audio is detected. A configuration is described in which a sound information output method using audio is determined and automatically output. Thereby, when the driver is awake, it is possible to perform unexpected alerting when the driver feels drowsy without causing the driver to feel bothered.

As described above, various methods have been developed for controlling the mind and body state of the passenger by grasping the mind and body state of the passenger of the vehicle and applying some stimulus to the passenger.

[Constitution]
(A) Overall Configuration First, the overall configuration of the mobile occupant's mind-body state adjusting apparatus 10 according to the present invention will be described.
As shown in FIG. 1, the mind-body condition adjusting device 10 is equipped with a biometric information sensor (mental-body information detecting means) 1A and a passenger (driver or passenger) based on information detected by the biometric information sensor 1A. A control device 7 for controlling a mind-body state of a pet (including a pet), a notification device (notification means) 8 for notifying the mind-body state, and a stimulus applying device for adjusting a mind-body state by applying a stimulus to a passenger 9. In the present embodiment, the case where the control target is a driver is exemplified as a specific representative example.

The biological information sensor 1A is a sensor that detects the mind and body information of the driver. Here, the pulse sensor 1Aa, the pressure sensor 1Ab, and the heart rate sensor 1Ac are illustrated as sensors that detect the vital signs of the driver.
In general, vital signs mean the physical signals that are the most basic of grasping the physical condition as vital signs. The vital signs here are physical quantities as vital signs detected from the body. Of these, it means that the vehicle has a correlation with a mental state such as a driver's relaxed state or stress state. For example, respiratory rate, heart rate, body temperature, skin surface temperature, skin potential, pulse wave (pulse rate), electroencephalogram, blood flow, body fluid components such as saliva, respiratory air and blood oxygen saturation, blood sugar level, body Dynamics, electrocardiogram, electrical conductivity, body weight (pressure on the seating surface), number of blinks, amount of sweat, strength of gripping handle, other electromagnetic waves and chemical substances emitted by the body. Information such as the magnitudes of these vital signs, their changes, and the slopes of the fluctuations is detected as physical and mental information by the biological information sensor 1A.

  Both the pulse sensor 1Aa and the pressure sensor 1Ab are attached to a handle of a moving body (in the present invention, steering control devices such as a steering, a control stick, and a control wheel are collectively referred to as a handle). The pulse sensor 1Aa detects the pulse wave of the driver, and the pressure sensor 1Ab detects the strength of the force for gripping the handle of the moving body (grip strength, pressure). The heart rate sensor 1Ac is attached to the backrest portion of the driver's seat and detects the driver's heartbeat. Information detected by these sensors 1Aa, 1Ab, and 1Ac is input to the control device 7.

  The control device 7 includes a passenger health condition determination unit 3, a passenger / moving body database 5a, a stimulation database 5b, a first personalization unit 6a, a second personalization unit 6b, and a third personalization unit (stimulation signal). Generating means) 6c and an electronic control unit (computer), which is provided inside the instrument panel of the moving body. The control device 7 and the above-described sensors 1Aa, 1Ab, 1Ac are connected via a wire harness.

  The passenger / mobile object database (hereinafter also simply referred to as a database) 5a is a memory device as a database for storing information relating to passengers and mobile objects. This includes, for example, the target value (target state) of the driver's mind and body state, the inclination of fluctuations of the driver's mind and body information in normal times (that is, the individual characteristics and characteristics that are different for each driver), A kind of mind and body information in which a mind and body state is easily reflected, a plurality of notification modes, and the like are stored.

Here, the inclination of the fluctuation of each mind and body information of the driver in the normal state stored in the database 5a will be described. First, when a driver purchases a moving body or installs a mind-body state adjustment device on an existing moving body, the driver's mind-body information is normally stored in advance (when the moving body is stopped or when it is running calmly). Measure all signals (here, pulse wave, grip strength, heart rate). If necessary, these signals are preprocessed by filtering, chaos analysis, wavelet analysis, etc., and then a fractal index is obtained by fractal analysis such as Detrended Fluctuation Analysis (DFA) or multifractal analysis. The fractal index at the time of normal, as a target value (reference value) F ₀ of mental and physical states of the driver, and stored in the database 5a.

Since such a fractal index is typically derived from the correlation between the time scale and the magnitude of signal fluctuation (the slope of the graph plotting both), in the present invention, the “fluctuation slope” is synonymous with the fractal index. Use as a word.
Of the above methods, DFA means that time series data is divided by a specific scale (window size), the magnitude of fluctuation after subtracting the trend in each window is obtained, and the magnitude and time of this fluctuation. This is an analysis method for log-log plotting the correlation with the scale. The method is described in detail below.

1. First, N-time time series data x (i), i = 1, 2,... N is subtracted from the average value X _avr to obtain new time series data y (k), k = Create 1,2, ... N. The average value X _avr and the time series data y (k) are described as in the following equations 1 and 2.

2. The time series data y (k) is divided into time scale (window size) n regions on the time axis (k). That is, the time series data y (k) is divided by a window composed of n pieces of data.
3. The mth order polynomial (where m is an integer such as 0, 1, 2,... And typically m = 1 is used) is applied to the time series data y (k) in each window. To obtain the trend y _n (k) in each window.

５．ウィンドウサイズnを変化させたときの揺らぎの大きさFL(n)を求め、log₁₀nとlog₁₀FL(n)との関係をグラフ上にプロットする。これをＤＦＡプロットと呼ぶ。このプロットに直線をあてはめる（直線近似する）ことができれば、その直線の傾きがもとの時系列データx(i)のフラクタル指数となる。 4). The fluctuation magnitude FL (n) after subtracting the trend y _n (k) from the time series data y (k) is obtained according to the following equation 3.

5. The fluctuation magnitude FL (n) when the window size n is changed is obtained, and the relationship between log ₁₀ n and log ₁₀ FL (n) is plotted on the graph. This is called a DFA plot. If a straight line can be applied to this plot (linear approximation), the slope of the straight line becomes the fractal index of the original time series data x (i).

The database 5a is subjected to the initial work as described above. The target value F ₀ varies depending on the driver, but if it is a value close to 1, it is considered that the target value F ₀ is in a healthy state on average.
The stimulation database 5b is a database that stores information on the type of stimulation given to the driver by the device 10 and information on the stimulation method (stimulation mode). In the present embodiment, a plurality of various sounds (speech, music, melody, etc.) are stored in the stimulus database 5b. For example, classical music such as Mozart and Beethoven, pop songs, birdsong and waves It stores a wide variety of sounds such as natural sounds such as sounds.

The functions of these databases 5a and 5b are realized by, for example, a hard disk or other storage medium.
The passenger health state determination unit 3 is a control unit (CPU, central processing unit) that determines the mind and body state of the driver. The first personalization unit 6a, the second personalization unit 6b, and the third personalization unit 6c are optimization means for optimizing (personalizing) the functions of the device 10 for each driver.

The notification device 8 is a monitor device for displaying and notifying the passenger of the determination result and notification content in the device 10, and an acoustic device or speaker for notification by voice. Here, the driver's mind and body state and the health state of the moving body, which will be described later, are notified. The stimulus applying device 9 is a device for applying a stimulus to the driver. The notification device 8 and the stimulus applying device 9 are connected to the control device 7 via a wire harness. In the present embodiment, the acoustic device of the notification device 8 also functions as the stimulus applying device 9. In the present embodiment, various music is played in accordance with the stimulation signal (electrical signal) input from the control device 7, and for example, the heart rate decreases and the mind and body condition is excessively relaxed. When it is recognized that the person is present, the heart rate is increased with an exciting song. This will be described later.

(B) Details of Configuration Next, details of the configuration of the control device 7 will be described.
The passenger health state determination unit 3 includes an analysis unit (mental body / body state analysis means) 3a that analyzes driver's mind and body information data, a passenger target state setting unit 3b that sets a target state of the driver's mind and body state, and a driver's state A determination unit 3c for determining the current mental and physical state is provided.

(B-1) Configuration of Analysis Unit 3a The analysis unit 3a analyzes the mind-body information obtained by the biological information sensor 1A using various analysis methods, and grasps the mind-body state of the driver.
Specifically, for analysis of mind and body information, known analysis methods (including nonlinear analysis methods) such as spectrum analysis (FFT analysis), fractal analysis, chaos analysis, wavelet analysis, etc. are used. An analysis method is selected. For example, techniques such as spectrum analysis (FFT analysis), fractal analysis, and chaos analysis are mainly used for periodic signals such as heartbeats and pulse waves. On the other hand, wavelet analysis, multifractal analysis, and the like are mainly used for intermittent (such as periodicity) signals such as body movements such as gripping force and wrinkles.

  A case where fractal analysis is performed using a heartbeat (biological rhythm) will be described in detail as a representative. First, we consider human heartbeats to be “waves” that change slightly under the influence of the state of the living body and surrounding environment. For example, it is a wave measured as a voltage fluctuation by an electrocardiograph or the like. This wave is difficult to quantitatively analyze the fluctuation because the period and the magnitude of vibration are not always constant.

Therefore, this wave is regarded as a periodic wave (repetitive waveform), the period of heartbeat variability is measured, and the time interval between the peaks of the waveform is extracted as the period of the biological rhythm. Then, a fractal analysis is performed on the time series of this period to quantitatively grasp the complexity of wave fluctuation.
In general, biological signals (biological rhythms) including heartbeats are non-stationary signals that contain a lot of noise and whose statistics such as average value and variance change over time. Removes noise and trends (unsteady fluctuation components that exist in time series). Thereafter, the fluctuation magnitude of the heartbeat signal with respect to the time axis is calculated.

There is a correlation between the magnitude of the fluctuation component and the time scale obtained as a result. For example, the vertical axis represents the logarithm of the fluctuation component magnitude (power of fluctuation), and the horizontal axis represents the time scale (variation of fluctuation). When the logarithm of (frequency) is taken and plotted on the graph (so-called log-log plot), the function graph of the fluctuation component and the frequency becomes substantially linear. Using such characteristics, the analysis unit 3a calculates the magnitude F ₁ of the fluctuation inclination and grasps it as an index of the mind and body condition.

Depending on the type of time-series data, this correlation may not be approximated by a single straight line. In this case, the time axis (frequency axis) may be divided into several regions so that a straight line is locally applied, and the fluctuation slope in each region may be obtained. Alternatively, a spectrum having a continuous fluctuation gradient F ₁ may be obtained by a multifractal analysis method. In such a case, the magnitude F ₁ of the fluctuation inclination is composed of a combination of one or more numerical values, so that a representative one may be selected and compared with the target value F ₀ , or vice versa. A plurality of target values F ₀ may be set for each of the plurality of F ₁ .

Incidentally, the analysis unit 3a for each of the mental and physical information detected by the biological information sensor 1A, the slope of the magnitude of fluctuation (analysis value) is calculated F _1. Further, where the calculated the each analysis value F ₁ is adapted to be inputted to the occupant goal state setting unit 3b and the first personalization unit 6a.

(B-2) Configuration of Passenger Target State Setting Unit 3b (1 / f fluctuation)
The occupant target state setting unit (target state setting means) 3b is a target state of the driver's mind and body state (that is, the driver's mind and body state as a control target, and is healthy for the mobile body, the driver and the passenger) Set the desired state).

Recent studies have reported that, for example, in the heartbeat fluctuation of a relaxed human, the fluctuation power is in a state where the slope is an absolute value 1 with respect to the frequency of the heartbeat wave. Such a state is referred to as 1 / f fluctuation, and it has been found that a 1 / f fluctuation state is a favorable psychosomatic state for a living body. Therefore, it is preferable that the mind and body state of the driver is set so as to be in the 1 / f fluctuation state, and the target state is set so that the mind and body state is in the 1 / f fluctuation state. In the present embodiment, the target value F ₀ of the mind and body state of the normal driver stored in the database 5a is set as this target state.

As a simple setting, the target value F ₀ of the fluctuation inclination may be set to F ₀ = 1. The fluctuation slope (fractal index) F ₀ has a characteristic that it increases as the fluctuation has a long-term positive correlation, and approaches zero as the fluctuation is regular and has a negative correlation. That is, the state in which the fractal index F ₀ is F ₀ = 1 is a state of natural fluctuation behavior in which fluctuation is moderately irregular.
Further, depending on the driving situation, it is preferable to maintain a moderate tension state, and it may be considered that the 1 / f fluctuation state released from the tension state may produce an undesirable result. Therefore, the slope of fluctuation that maintains an appropriate tension state necessary for driving according to individual differences (the index n when the slope in the correspondence between the magnitude of the fluctuation component and the frequency f is expressed as 1 / f ^n. Then, a value of a so-called fractal index) may be obtained, and the target state may be set so that the 1 / f fluctuation state at that value is obtained (personalization of the target state).

For example, when traveling in a tunnel or at night, it is preferable that the driver concentrates on driving while maintaining a moderately tensioned state compared to the normal time. Therefore, it is conceivable to set the fluctuation slope F ₀ set as the target state to a value slightly smaller than 1. In the process of personalizing the target state, a desired target state value may be learned, which will be described later.

(B-3) Configuration of Determination Unit 3c The determination unit 3c compares the real-time psychosomatic information analysis result obtained by the analysis unit 3a with the target state set by the occupant target state setting unit 3b, The physical and mental state MB of the driver is determined.
Specifically, the target value F ₀ of the fractal index set as the target state in the occupant target state setting unit 3b and the analysis value of the fractal index calculated by the analysis unit 3a (that is, the inclination of fluctuation of heart rate variability). by comparing the F _1, as shown in FIG. 3, if the a F ₁ and F ₀ substantially matches _{(F 0 -α ≦ F 1 ≦} F 0 + α), the mental and physical states MB of the driver ' It is determined that the state is appropriate. Here, α is a predetermined value set in advance for determining the degree of similarity between F ₁ and F ₀ .

If F ₁ is smaller than F ₀ (F ₁ <F ₀ −α), “I feel stress”, “I feel a little stress”, “Very much stress” as the degree of deviation increases. "I feel stress." On the contrary, if F ₁ is larger than F ₀ (F ₁ > F ₀ + α), “relaxing”, “relaxing”, “relaxing excessively” as the divergence increases. It is decided that it is. That is, the mental and physical state is determined by classifying into seven stages. Such a classification and the setting of the predetermined value α are examples, and may be implemented with various changes such as further subdivision of the classification.

(B-4) Configuration of first personalization unit 6a (personalization of sensor selection)
The first personalization unit 6a extracts information [optimal mind-body information (optimized mind-body information)] that most reflects a change in the mind-body state of the driver from mind-body information input from the biological information sensor 1A. , Accurately grasp the state of mind and body according to the individual. Specifically, it is estimated that the information that the driver's stress state is sharply reflected out of the pulse wave, grip strength and heart rate, and select (personalize) according to the individual. It has become.

  In the present embodiment, the inclination of fluctuation of each mind and body information (that is, individual personality and characteristics that are different for each driver) in the normal time (when the moving body is stopped or when driving is calm) is stored in the database 5a in advance. It is remembered. This is the reference value for the driver's mind and body condition. And the 1st personalization part 6a compares the inclination of the fluctuation of the mind and body information of these drivers in normal times with the inclination of the fluctuation of each mind and body information analyzed by the analysis part 3a, Select the mind and body information (optimal mind and body information) that has the greatest fluctuation from normal. That is, here, information that is estimated to be the most responsive among the detected mind-body information is extracted.

  In this embodiment, personalization of sensor selection is selected based on the reactivity of detected information. For example, a questionnaire or a test is performed on the driver in advance and statistically estimated. It is good also as a structure which selects optimal mind-body information, and it is good also as a structure in which a driver | operator selects favorite information himself.

(B-5) Configuration of second personalization unit 6b (personalization of notification method)
The 2nd personalization part 6b is a control part which changes the alerting | reporting method of the mind and body state alert | reported to the driver | operator by the alerting device 8 according to an individual. Specifically, one notification mode is selected from a plurality of notification modes stored in the database 5a based on the mind and body state MB of the driver, and the notification device 8 is instructed. . Thus, for example, when the mind and body state MB of the driver feels stress, control is performed such that notification is made with a gentle color tone and notification is made with a gentle voice.

  In addition, in the analysis part 3a, it is possible to add the structure which grasps | ascertains a driver's sensitivity from the analysis of mind-body information, and to change an alerting | reporting method based on the grasped driver's sensitivity. That is, the control is performed such that the driver with high sensitivity is notified with a gentle display and with a gentle voice. Thereby, it is possible to select a notification method more suitable for an individual. Moreover, the influence on the mind and body state given by the notification can be reduced.

(B-6) Configuration of third personalization unit 6c (personalization of stimulus applying method)
The third personalization unit 6c is one of a plurality of stimulus application modes stored in the stimulus database 5b based on the driver's mind-body state MB calculated from the mind-body information extracted by the first personalization unit 6a. It is a control unit for selecting the above stimulation method, generating a stimulation signal, giving an instruction to the stimulation applying device 9, and applying the stimulation to the driver. Specifically, the third personalization unit 6c generates a stimulus signal that most reflects a change in the driver's mind-body state MB among a plurality of stimulus signal generation modes in order to make the driver's mind-body state MB a target state. A mode is selected.

  That is, for example, when tension or irritation increases (becomes stressed) and the fractal index decreases, a Mozart music that restores 1 / f characteristics and a stimulus signal generation mode for applying a stimulus of flowing natural sound (relaxed music) Mode) is selected. Conversely, if the driver is overly relaxed and lacks the tension necessary for driving, a song with a good tempo can be selected to generate a stimulus signal that allows the driver to maintain a healthy mental and physical state (tension music) Mode) is selected. Further, for example, the larger the difference between the driver's mind and body state MB and the target state (that is, the greater the amount of adjustment of the mind and body state), the higher the music volume is selected.

[Action]
The moving body occupant's mind-body state adjusting apparatus according to the first embodiment of the present invention is configured as described above, and is controlled according to the following flowchart.
(Analysis flow)
First, in the control device 7, an analysis flow for analyzing the mind and body information of the driver is performed as shown in FIG.

In step A10, basic information (target value F ₀ ) stored in the database 5a and related to the mind and body state of the driver at normal times is read out and grasped.
Next, in step A20, three types of driver's mind and body information are detected by the information sensors 1Aa, 1Ab, and 1Ac from the time when the driver gets on the moving body (that is, during actual travel).

In step A30, the information sensor 1Aa, 1Ab, each psychosomatic information detected by 1Ac, analyzed using various analysis methods in the analysis unit 3a, the analysis value F ₁ is calculated.
In step A40, the first personalization unit 6a, and each analysis value F ₁ of the driver obtained by analyzing in step A30, are compared with target values F _0, which is grasped in step A10. Then, by comparing the combinations of numerical values (F ₁ , F ₀ ) obtained from each mind-body information, the mind-body information estimated to have the highest reactivity (responsiveness) is extracted. That is, optimal mind-body information is selected. In Step A40, when this optimal mind-body information that changes in a sensitive manner reflecting changes in the mind-body state of the driver is selected, such optimum mind-body information is used as important mind-body information (for grasping the mind-body state of the driver). May be stored in the database 5a as the information suitable for the next time, and only the optimal mind-body information may be measured and analyzed in the subsequent control. Thereby, the analysis burden in the control apparatus 7 can be reduced. Of course, psychosomatic information determined to be unimportant may not be ignored as the situation changes, so it is necessary to check it periodically.

In step A50, the judgment unit 3c, an analysis value F ₁ of the optimum psychosomatic information selected in step A40, the stored reference values in the database (target value) F ₀ and is compared, as shown in FIG. 2 The psychosomatic state is determined based on the degree of deviation of the optimal analysis value F _{1 from} the target value F ₀ . For example, if the analysis value F ₁ of the driver is within the range of F ₀ ± α, it is determined that the person is in a state of mind and body appropriate for driving. And when it determines with it being appropriate, it progresses to step A60, and when that is not right, it progresses to step A70.
In step A60, the notification device 8 notifies the driver that the current state of mind and body of the driver is appropriate for driving. On the other hand, in step A70, the display flow described below is performed.

(Display flow)
A display flow for notifying the driver of the state of mind and body ascertained by the control device 7 is performed as shown in FIG.

In step B10, the second personalization unit 6b reads a plurality of notification methods from the database 5a. That is, a soft (gentle) display method, a hard (psychologically appealing) display method, and the like are read so that notification can be appropriately made according to the mind and body state of the driver.
In Step B20, the analysis value F ₁ analyzed in Step A30 of the previous analysis flow is read.

In step B30, _one of the plurality of notification modes read in step B10 is selected on the basis of the analysis value F1 read in step B20, based on the mind and body state of the driver, and the notification device 8 is instructed. Is made. For example, when the driver's mind-body state level MB is low and it is estimated that he / she feels stress, the display is made in a gentle color tone, and a gentle voice is notified.

In step B40, based on the instruction made in step B30, the notification device 8 notifies the driver of the mental and physical condition.
Then, it progresses to the stimulation flow of step B50.

(Stimulation flow)
The stimulus flow for giving the driver a stimulus for adjusting the mind and body state grasped by the control device 7 is performed as shown in FIG.
In Step C10, the third personalization unit 6c reads a plurality of stimulus applying methods from the stimulus database 5b. Here, the voice mode (sound) is read together with the voice providing method by the acoustic device.
In step C20, the analysis value F ₁ which is selected in step A30 of the previous analysis flow is read.

In step C30, based on the analysis value F ₁ read in step C20, and one is selected from among a plurality of stimulating manner read in step C10, instruction is made to the stimulating device 9. That is, here, the stimulation signal (for example, Mozart music, natural sound, tempo of the tempo) generated according to the stimulation signal generation mode (for example, the relaxation music mode, the tension music mode, etc.) selected by the third personalization unit 6c. A good song, etc.) is transmitted to the stimulating device 9. For example, when the driver's mind and body state level MB is low, a stimulus signal generation mode of playing Mozart music or natural sound is selected. In addition, when the psychosomatic state level MB is high, a song with a good tempo is selected.

  In step C40, a stimulus (sound) is applied to the driver by the stimulus applying device 9 based on the instruction made in step C30. That is, as a result of the control by the present apparatus as described above, the driver's mind-body state level MB approaches 0, and an appropriate balance between the stress state and the relaxed state is maintained.

[effect]
According to the present mind-body condition adjusting apparatus 10, the following effects can be obtained.
First, since the control device 7 is provided with three optimization means of the first personalization unit 6a, the second personalization unit 6b, and the third personalization unit 6c, the control optimized for each driver is provided. It is possible to adjust the mental and physical state according to different health conditions and their maintenance and promotion methods. And it can help a driver | operator drive a moving body safely.

  Moreover, the mind-body information for grasping | ascertaining a driver | operator's mind-body state can be selected by the function of the 1st personalization part 6a. That is, it is possible to select from a plurality of types of information that reflects a change in health condition that differs depending on the individual. For example, some people tend to fluctuate their pulse waves due to an increase in stress, while others tend to roughen the way of steering the handle (the magnitude of the force to grip the handle, the speed of turning the handle, the acceleration, etc.). Therefore, in order to accurately grasp the degree of stress of an individual person, it is preferable to use psychosomatic information having high responsiveness and responsiveness to stress for each individual. It is possible to select mental and physical information in consideration of such different characteristics for each individual.

In addition, since the first personalization unit 6a compares the driver's normal mind and body information with the mind and body information detected by the biological information sensor 1A, the reactivity and responsiveness to changes in the mind and body state are compared. It is possible to select the most optimal psychosomatic information.
In addition, analysis based on psychosomatic information that has the highest responsiveness and responsiveness to changes in psychosomatic state makes it possible to easily analyze the psychosomatic state of the driver and improve the reliability of the analysis results. .

Further, the third personalization unit 6c can select a stimulus application mode for controlling the mind and body state of the driver. In other words, it is possible to improve the reliability of the control by selecting the stimulus application mode that has the highest effect and influence on the mind and body state that varies depending on the individual, and it is easy to make the mind and body state of the driver a target state. Become.
For example, when the driver's mind and body state level MB is low, Mozart music and natural sounds are selected, while when the mind and body state level MB is high, a song with a good tempo is selected. Efficiency can be increased.

  Further, by providing the second personalization means 6b, it is possible to select a notification mode with little influence on the driver's mind and body state. For example, when the driver's sensitivity is strong, the notification of the analysis result may cause the driver's mind-body state to change from the analyzed mind-body state. As a result, it is possible to improve the reliability of the control.

Further, since the psychosomatic information is analyzed by a non-linear analysis method, the non-linear relationship between the stimulus and the psychosomatic information can be analyzed quickly and accurately, and the driver's psychosomatic state can be adjusted appropriately.
In addition, since the driver's body movements and heels, such as the grip strength to grasp the steering wheel, can be used to grasp the mind and body state, the driver's conscious response and reaction can be eliminated, and the driver's mind and body state can be analyzed more accurately. can do.

  Further, since the sensors for detecting the mind and body state of the driver are attached to the moving body and are not directly attached to the driver, the mind and body information can be detected non-invasively from the passenger. That is, it is possible to suppress changes in the mind and body information itself that can be caused by detecting the mind and body information. The sensors may be attached to the body in a range that does not cause the driver to feel uncomfortable.

[Second Embodiment]
[Constitution]
Next, a second embodiment will be described. 6 and 7 show a mobile occupant's mind-body condition adjusting apparatus according to a second embodiment of the present invention. FIG. 6 is a block diagram showing the overall configuration of the apparatus. FIG. 7 shows a mind-body state in the apparatus. It is a flowchart which shows this analysis control. In addition, the same code | symbol is attached | subjected to the component same as 1st Embodiment, and description is partially abbreviate | omitted.

As shown in FIG. 6, the psychosomatic condition adjusting device 20 according to the second embodiment newly includes a learning unit (learning means) 11 and a stimulus changing device 12 in addition to the configuration of the first embodiment. The method for setting the target state of the mind and body state of the driver is different from the mind and body state adjustment device 10 according to the embodiment.
The stimulus change device 12 is a device for canceling (stopping), actuating and changing the stimulus applied to the driver by the control device 7, and includes a stimulus applying button 12a, a stimulus stop button 12b, a stimulus change button 12c, And a control direction setting switch 12d. The operation signals of the stimulus applying button 12a, the stimulus stop button 12b, the stimulus change button 12c, and the control direction setting switch 12d by the driver are input to the control device 7 and the learning unit 11.

  The stimulus applying button 12a is a button for applying a stimulus to the control device 7 when the driver does not give a stimulus and the driver desires the stimulus. That is, the stimulus imparting button 12a functions to reverse the determination result “no stimulus is imparted” in the control device 7. When the stimulus applying button 12a is operated, the control device 7 starts applying the stimulus by the stimulus applying device 9.

  On the other hand, the stimulus stop button 12b is a button that is operated when a stimulus is given to the driver and the driver does not want the stimulus, and causes the control device 7 to finish giving the stimulus. is there. That is, the stimulus stop button 12b functions to reverse the determination result of “applying stimulus” in the control device 7. When the stimulus applying button 12a is operated, the control device 7 stops applying the stimulus by the stimulus applying device 9.

The stimulus change button 12 c is a button for changing the stimulus given by the control device 7. When the stimulus change button 12 c is operated, the control device 7 changes the stimulus applying mode by the stimulus applying device 9. In the present embodiment, the stimulus application mode is changed by changing the target value F ₀ of the fluctuation inclination.
The control direction setting switch 12d is controlled by the driver's willing control direction (i.e., applying the stimulus) when the stimulus applying mode is changed by the driver's will by operating the stimulus applying button 12a and the stimulus changing button 12c. This is a switch for inputting the direction of the mind and body state. For example, the control direction setting switch 12d is provided as a dial-type rotary switch, and when the driver wants to relax more as a driver's subjectivity, the control direction setting switch 12d is rotated to the relax side. It is designed to be rotated.

On the other hand, the learning unit 11 is a control unit that learns the target state suitable for the driver, and corrects the target value F ₀ of the fluctuation inclination according to the change in the mind and body state due to the application of the stimulus to the driver (that is, , Learning).
Specifically, when the operation signal of the stimulus stop button 12b is input while the control device 7 is applying the stimulus, the learning unit 11 sets the inclination of the fluctuation set in the occupant target state setting unit 3b. Target value F ₀ and the analysis value F ₁ of the mind and body state of the driver analyzed by the analysis unit 3a are read, and the target value F ₀ stored in the database 5a is corrected so as to approach the analysis value F _1. . In other words, when the driver cancels the application of the stimulus, the subject's subjectivity is considered to be in a good state of mind and body, and the current analysis value F ₁ is learned as an index of the target state.

Further, when the operation signal of the stimulus change button 12c is input while the control device 7 is applying the stimulus, the learning unit 11 reads the operation amount of the control direction setting switch 12d and stores it in the database 5a. The target value F ₀ is changed to the control direction as the driver's will.
Similarly, when the operation signal of the stimulus applying button 12a is input in a state where the control device 7 does not apply the stimulus, the learning unit 11 reads the operation amount of the control direction setting switch 12d and stores it in the database 5a. The set target value F ₀ is changed in the control direction according to the will of the driver. That is, at the time when a change or application of a stimulus is requested by the driver, it is considered that the mind and body state is not in a good state according to the driver's subjectivity, and the target state index is set by the control direction setting switch 12d. Learn to correct in the direction.

It should be noted that the analysis value of the driver's mind-body condition after the stimulus is given by the driver's stimulus application button 12a is read, and the target value F ₀ is set as the analysis value after the driver's active stimulus change. You may correct | amend so that it may approach. That is, in this case, learning is performed assuming that the mind-body state after the stimulus is changed by the driver's subjectivity is a better mind-body state for the driver.
The target state learned in this way is sequentially updated as a new target value F ₀ and stored in the database 5a.

[Action / Effect]
The control contents in the control device 7 of the second embodiment will be described with reference to the flowchart shown in FIG.
First, in step D10, as an initial operation, preset typical target value for the mental and physical states of the driver (reference value) F ₀ is read from the database 5a.
In step D20, three types of driver's mind and body information are detected by the information sensors 1Aa, 1Ab, and 1Ac from the time when the driver gets on the moving body (that is, during actual travel).

In step D30, the information sensor 1Aa, 1Ab, each psychosomatic information detected by 1Ac, analyzed using various analysis methods in the analysis unit 3a, the analysis value F ₁ is calculated.
In step D40, the first personalization unit 6a compares each analysis value F ₁ of the driver obtained by analysis in step D30 with each target value F ₀ obtained in step D10. Then, information that is estimated to be the most responsive among the psychosomatic information is extracted. That is, optimal mind-body information is selected.

In step D50, the determination unit 3c, an analysis value F ₁ of the optimum psychosomatic information selected in step D40, the stored reference values in the database (target value) and F ₀ are compared, as shown in FIG. 2, The psychosomatic state is determined based on the degree of deviation of the analysis value F ₁ of the optimum information from the target value F ₀ . For example, if the analysis value F ₁ of the driver is in the range of F ₀ ± α, it is determined that the person is in a state of mind and body appropriate for driving. And when it determines with it being appropriate, it progresses to step D60, and when that is not right, it progresses to step D100.

In step D60, the second personalization unit 6b notifies the driver that the current state of mind and body of the driver is appropriate for driving. In this case, the control device 7 determines that the driver's mind and body state is appropriate and that no stimulus is required.
In subsequent step D70, it is determined in the control device 7 whether or not the driver has operated the stimulus applying button 12a. Here, when the driver selects the operation of the stimulus applying device 9 by the stimulus applying button 12a even though it is originally determined that the driver's mind and body state is appropriate, in the driver's subjectivity, It is determined that the current mental and physical state, that is, the target value F ₀ is not appropriate.

Therefore, in step D80, based on the rotation operation amount of the control direction setting switch 12d, the target value F ₀ is changed to control the direction of the driver's intention, it is corrected learned. That is, the target value F ₀ corrected here is stored in the database 5a.
In step D90, the third personalization unit 6c, based on the target value F ₀ Fixed learning and analysis values F _1, which is analyzed in step D40, stimulus is imparted to the driver.

  On the other hand, in step D100, the notification device 8 notifies the driver that the current driver's state of mind is not appropriate for driving by the second personalization unit 6b. In this case, the control device 7 determines that the driver's mind and body state is not appropriate and that stimulation needs to be applied. In step D110, the stimulus is applied by the stimulus applying device 9 in the third personalization unit 6c according to the state of mind and body of the driver.

In step D120, it is determined in the control device 7 whether or not the driver has operated the stimulus stop button 12b or the stimulus change button 12c. Here, when the driver cancels the operation of the stimulus applying device 9 by the stimulus stop button 12b even though it is originally determined that the driver's mind and body state is inappropriate, Is determined to be appropriate, that is, the target value F ₀ . Similarly, when the driver has changed its stimulation by stimulation change button 12c would target value F ₀ of the driver to be adjusted by the stimulation is determined to be unsuitable.

Therefore, in step D130, when the driver cancels the operation of the stimulating device 9 by operating the stimulation stop button 12b is corrected so as to approach the target value F ₀ in the analysis value F ₁ of the current psychosomatic information. Further, when the driver changes the stimulation by stimulating device 9 operates the stimulus change button 12c on the basis of the rotational operation amount of the control direction setting switch 12d, the control target value F ₀ is the intention of the driver The direction is changed and learning is corrected. Then, the target value F ₀ is stored in the database.

  As described above, according to the mobile occupant's mind-body state adjusting apparatus 20 according to the second embodiment, by learning the target state, the occupant's mind-body state becomes a target state suitable for each person more appropriately. Can be adjusted as follows. In addition, in order to correct the target state stored in the database 5a in the learning process, for example, even when the normal input data as the initial work performed when the driver purchases the moving object is scarce, the learning is performed. By repeating the above, it becomes possible to set a highly accurate target state.

[Third Embodiment]
Next, a third embodiment will be described. 8 to 10 show a mobile occupant's mind-body condition adjusting apparatus according to a third embodiment of the present invention. FIG. 8 is a block diagram showing the overall configuration of the apparatus, and FIG. 9 is a health state of the mobile body.

Here, a steering angle sensor 1Ba that detects the operation amount (steering angle) of the steering wheel and a moving body speed sensor 1Bb that detects the traveling speed of the moving body are illustrated.
In addition, as other moving body information, steering angular velocity, distance between moving bodies, moving body indoor temperature, moving body indoor humidity, etc. can be considered. To detect these, for example, an acceleration sensor that detects acceleration, an accelerator sensor that detects the driver's accelerator operation, a brake sensor that detects the driver's brake operation, a fuel consumption sensor that detects fuel consumption, and tire wear detection It is preferable to use a tire sensor or the like that is appropriately selected from these.

The environment information sensor 1 </ b> C is a sensor that detects a physical quantity (environment information) related to the external environment of the passenger and the moving body. Here, a temperature sensor 1Ca that detects the temperature outside the moving body room and a humidity sensor 1Cb that detects humidity are illustrated.
In addition, as other environmental information, weather, time, etc. can be considered, and sensors and timers for detecting and measuring these may be provided as appropriate.
Information detected by these various sensors is input to the control device 7.

(B) Details of Configuration The control device 7 includes a health condition determination unit 2, a passenger / moving body database 5a, a stimulation database 5b, a first personalization unit 6a, a second personalization unit 6b, and a third personalization. And a portion 6c. The health state determination unit 2 is a control unit that determines the mind and body state of the driver and the health state of the moving body.

The health condition determination unit 2 includes a passenger health condition determination unit 3 and a moving body health condition determination unit 4. The passenger health state determination unit 3 is a control unit that determines the mental and physical health state of the driver as described in the first embodiment. The mobile body health state determination unit 4 is a control unit that determines the health state of the mobile body (running state, maintenance state, mobile body indoor environment, etc.).
The moving body health state determination unit 4 includes a moving body state grasping unit (moving body state grasping means) 4a and a moving body target state setting unit 4b.

(B-1) Configuration of the moving body state grasping unit 4a The moving body state grasping unit 4a analyzes the moving body information obtained by the moving body information sensor 1B using various analysis methods, and determines the health state of the moving body. It comes to grasp.
The health state of the moving body refers to the 1 / f fluctuation of the moving body information. The 1 / f fluctuation of the moving body is grasped using a known analysis method (including a non-linear analysis method), similarly to the analysis of mind and body information. In the present embodiment, similarly to the calculation of the magnitude F ₁ of the fluctuation of the driver's mind and body state in the first embodiment, the fluctuation inclination (analysis value) F ₃ of the moving body is calculated. Yes.

Here, the meaning of grasping the health state of the moving body will be described.
For example, when the driver's mind and body information and the moving body information of the moving body are measured and analyzed during driving in the wilderness where there is no signal or traffic jam, as shown in FIG. Both the time-series data of the detected mind-body information and the time-series data of the moving body information obtained from the moving body show 1 / f fluctuation, and both show fluctuations that are substantially synchronized. That is, the health state of the moving body is analyzed from the moving body information in the same manner as the mind and body state of the driver is analyzed from the mind and body information.

It is known that in such a synchronized state of fluctuation between the moving body and the driver, the driver can feel a sense of unity with the moving body and obtain a good mental and physical state.
However, on a congested road in the city center, running and stopping are frequently repeated. For example, when the traveling speed of the moving body is analyzed, as shown in FIG. It becomes. In such a state, the driver's mind-body state is also tense and the 1 / f property is lost, and the driver feels stress. That is, the tension of the driver's mind and body state is reflected in the driving operation and the moving body behavior, and the 1 / f fluctuation property of the moving body information is lowered. In other words, in a situation where there are other moving bodies in the surroundings, so that people lose their freedom and feel stress in relation to others, they lose their original bulk to maintain a good distance from each other. It is.

Thus, the health state of the mobile body does not indicate whether the mobile body is in a healthy state (for example, a state where there is no failure or a high performance state), but as a barometer of the relationship with the driver. Have a meaning. Therefore, improving the health condition of the moving object leads to improving the driver's mental and physical condition.
Here, the time-series data of the mind and body information and the time-series data of the moving body information being synchronized do not mean that both show the exact same shape, but if they are in a temporally similar relationship Good. For example, if the fractal index of the time-series data of the timing of applying the brake on a congested road and the fractal index of the heart rate change of the driver show close values, it can be considered that both are synchronized. Moreover, if the value is in the appropriate range for driving, the driver and the moving body are integrated, and both are kept in a very healthy state even in a traffic jam. it can.

(B-2) Configuration of Moving Body Target State Setting Unit 4b Based on the above consideration, the moving body target state setting unit 4b has a health state of 1 / f that is determined by the moving body state grasping unit 4a. setting a target state F ₂ so that fluctuations state. In the present embodiment, the target value F ₂ of the fluctuation inclination is set to F ₂ = 1. The target value F ₂ set here is set in advance in the database 5a as a preferable target state of the moving body.

Depending on the traveling environment of the moving body, it may be preferable that the health state of the moving body is maintained in a moderately tensioned state. Therefore, the value of the inclination of fluctuation of the moving body may be set as the target state according to the environmental conditions. In this case, the target value F ₂ of the fluctuation inclination is set according to the environmental information detected by the environmental information sensor 1C. For example, the target value F ₂ may be set to be smaller than 1 in order to increase the degree of tension of the moving body during traffic jams, when traveling on congested roads, when traveling on narrow roads, and under rainy weather.

(B-3) Configuration of Determination Unit 3c As in the first embodiment, the determination unit 3c compares the driver's fluctuation target value F ₀ and the analysis value F ₁ to determine the driver's mental and physical state MB. In addition to the determination, the health state CH of the moving body is determined by comparing the target value F ₂ of the fluctuation of the moving body with the analysis value F ₃ . For example, here, as shown in FIG. 10, the health state CH of the moving body is classified into seven stages (levels -3 to +3) for determination.

(B-4) Configuration of first personalization unit 6a (personalization of sensor selection)
As in the first embodiment, the first personalization unit 6a extracts information (optimal psychosomatic information) that most reflects changes in the driver's psychosomatic state from the psychosomatic information input from the biological information sensor 1A. Then, grasp the state of mind and body accurately according to the individual. Specifically, it is estimated that the information that the driver's stress state is sharply reflected out of the pulse wave, grip strength and heart rate, and select (personalize) according to the individual. It has become.

Moreover, the 1st personalization part 6a extracts the information (optimum mobile body information) in which the change of the health state of a mobile body is most reflected among the mobile body information input from the mobile body information sensor 1B.
In this embodiment, the driver's mind and body information and the inclination of the fluctuation of the moving body information in normal times (when the moving body is stopped or when traveling is calm) (that is, the individuality and characteristics of each individual that is different for each driver, Different moving body characteristics and the like for each moving body are stored in the database 5a in advance. This is a reference value for the driver's mind and body condition and the health condition of the moving object.

Then, the first personalization unit 6a first compares the inclination of the fluctuation of the mind and body information of the driver in the normal state with the inclination of the fluctuation of the mind and body information analyzed by the analysis unit 3a. Select the mind and body information that has the greatest variation from time to time.
Next, the first personalization unit 6a compares the inclination of the fluctuation of the health state of the moving body information in the normal state with the inclination of the fluctuation of the moving body information calculated by the moving body state grasping unit 4a. Of the moving body information, the moving body information with the largest fluctuation from the normal time is selected.
That is, here, only the psychosomatic information and the moving body information that are estimated to be highly responsive are extracted from the detected information.

(B-5) Configuration of the Third Personalization Unit 6c The third personalization unit 6c provides stimulation based on the driver's mind-body state MB and the mobile body health state CH extracted by the first personalization unit 6a. It is a control part which gives an instruction | indication to the apparatus 9 and provides a driver | operator with a stimulus. Specifically, the third personalization unit 6c has the most change in the driver's mind and body state MB among the plurality of stimulus imparting modes in order to set the driver's mind and body state MB and the moving body's health state CH to the target state. The stimulus application mode to be reflected is selected.

  For example, when the average value of the driver's mind and body state MB level and the moving body's health state CH level is smaller than 0 (for example, the driver's mind and body state MB level is 1, the moving body's health state CH level is -3. In the case of (1), in order to eliminate the stress state of the driver and the moving body, the stimulus imparting mode is selected in which the scent of the fragrance is released while music is played and the tension is released. On the other hand, if the average value of the driver's mind and body state MB level and the mobile body health state CH level is greater than 0, the scent of the fragrance is supplied so as to play up-tempo music and enhance energy. Is selected.

[Action]
Since the mobile body occupant's mind-body adjustment apparatus according to the third embodiment of the present invention is configured as described above, it operates as follows.
First, in the biological information sensor 1 </ b> A, three types of mind and body information (pulse, grip strength and heartbeat) of the driver are detected and input to the control device 7. Further, the mobile body information sensor 1B and the environmental information sensor 1C detect mobile body information and environmental information and input them to the control device 7.

Each psychosomatic information inputted is analyzed by the fractal analysis in the analysis unit 3a, the analysis value (slope of the fluctuation) F ₁ is calculated for each of the mind and body information. Further, the mobile information is analyzed by the fractal analysis in a mobile state grasping unit 4a, the analysis value (slope of the fluctuation) F ₃ is calculated for each of the mobile information.
Subsequently, the first personalization unit 6a, by comparing the analytical values F ₁ and the calculated slope of the normal times of fluctuation of the mental and physical information stored in the database 5a, the variation from the normal state of the mind and body information The psychosomatic information having the largest (ie, the most responsive) is selected. Similarly, by comparing the inclination of the fluctuation of each moving body information in the normal time with the calculated analysis value F ₃ , the moving body information having the largest fluctuation from the normal time is selected from the moving body information.

In the passenger target state setting unit 3b, the target value F ₀ of the fluctuation inclination is set to F ₀ = 1 as the target state of the driver's mind and body state. The value F ₂ is set to F ₂ = 1.
Subsequently, the determination unit 3c determines the driver's mind-body state MB and the mobile body health state CH, and the third personalization unit 6c determines the driver's mind-body state MB and the mobile body health. In order to set the state CH to the target state, the stimulus application mode is selected. As a result, the stimulus is given to the driver by the stimulus applying device 9, and the mind-body state MB of the driver and the health state CH of the moving body both approach the target state. That is, the 1 / f property of the fluctuation of the mind and body state of the driver is restored, and the 1 / f property of the fluctuation of the health state of the moving body is also restored.

[effect]
As described above, according to the psychosomatic state adjusting apparatus of the third embodiment, the psychosomatic information of the occupant can be analyzed more non-invasively. For example, information on the amount of driving operation such as the amount of steering wheel operation or accelerator operation by the passenger is regarded as mind-body information, and the mind-body state of the passenger is determined based on the politeness and roughness of the operation required by analyzing the characteristics. I can grasp it.

  In addition, the state of mind and body of the occupant can be adjusted according to the health state of the mobile body, and a more comfortable mobile body environment can be provided. For example, if the tire pressure of a moving body, friction coefficient of a brake pad, etc. are detected as moving body information and the health condition of the moving body such as the appropriateness of the air pressure and the effectiveness of the brake is analyzed, the air pressure is slightly within the appropriate range. When the vehicle is low or the brake pads are slightly worn, the vehicle's health and boarding are controlled by controlling the vehicle's running speed so that it does not increase too much by relaxing the passenger's mind and body. It is possible to form and maintain a good cooperative relationship with the mental and physical state of the person.

  For example, when driving under rain, the target of the mental and physical state is set so as to be a little more tensioned than when driving under fine weather, thereby achieving control suitable for the driving environment. Moreover, if the target state is set according to the age, sex, driving skill, etc. of the individual, a comfortable driving environment for the individual can be provided.

[Others]
As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, A various deformation | transformation is possible in the range which does not deviate from the meaning of this invention.
<Modification 1>
For example, in the first embodiment described above, the occupant target state setting unit 3b is configured to set the fluctuation slope F ₀ as the target value of the driver's mind and body state. May be replaced with a method using a correlation between the sensing object and the mind and body state.

In other words, quantitative indicators (driver's heart rate, time series data average value, standard deviation, fractal index, Lyapunov index, etc.) obtained by analyzing all signals of mind and body information in advance, A method of calculating the correlation between the driver's mind and body state (sleepiness, irritability, risk prediction ability, etc.) in the form of a function or a map is used.
Since such a correlation depends on the individual driver, for example, the mind-body state that the driver feels subjectively while driving is recorded, and a correlation between this and a quantitative index is established.

The correlation can be described mathematically by a first-order regression analysis when the psychosomatic state and the quantitative index have a one-to-one correspondence. On the other hand, when there are a plurality of both, learning by multivariate statistical analysis or neural network is performed to determine which quantitative index combination best reflects the state of mind and body.
Next, based on the correlation established in this way, the influence exerted on the mind and body state by the display method and stimulation method of the mind and body state given to the driver is grasped.

  That is, various biological signals of the driver under various displays and stimuli are measured in advance to examine how the state of mind and body changes. When it is improved, it is considered that the display method and the stimulation method are suitable for the driver, and on the contrary, when it deteriorates, it is stored in the database 5a as being unsuitable. In the database 5a, the personal preference (preference) of the driver is input in advance by taking a questionnaire or the like. And based on the information memorize | stored in this database 5a, the alerting | reporting method to a driver | operator and the stimulus provision method are determined.

In addition, it is preferable to periodically review the database regarding these correlations.
If such a correlation is stored in the database 5a, the reference value relating to the analysis of the mind and body state of the driver can be optimized for each individual.

<Modification 2>
Moreover, in said 1st-3rd embodiment, although the pulse wave sensor 1Aa, the pressure sensor 1Ab, and the heart rate sensor 1Ac were detected as the biological information sensor 1A, the pulse wave, the grip strength, and the heart rate were detected. As shown in FIG. 11, a temperature sensor (infrared sensor) 1Ad and a respiratory sensor 1Ae are placed at appropriate locations on the moving body so that respiration, skin potential, body movement, etc. are detected and appropriately selected from these. , Skin potential sensor 1Af, body motion sensor 1Ag, weight sensor 1Ah, camera 1Ai, etc., may be appropriately selected from these. For example, the temperature sensor 1Ad may be attached to the horn portion of the steering wheel to detect the driver's body temperature, or the body motion sensor 1Ag or the weight sensor 1Ah may be embedded in the seating position of the seat to A driver's movement (癖) such as sitting down to the seat (sitting deeply to the back or sitting lightly only in the front) may be detected, and the camera 1Ai is provided near the rearview mirror. The driver's movement (動 き) such as the driver's blink interval may be detected.

The touch sensor 1Aj may be used to detect the driver's movement pattern. That is, the touch sensor 1Aj is attached to the rearview mirror, the side mirror adjustment switch, the window opening / closing switch, the seat adjustment switch, etc., and the order of contact with the touch sensor 1Aj when riding on the moving body is monitored. The state of mind and body may be determined based on whether they are different. Here, the exercise pattern means the order of the driver's actions. In general, the order of actions is standardized, and it is considered that it takes a fixed type in normal times. Under such an idea, if the movement pattern is different from the standardized movement pattern, the driver is not normal and the psychosomatic state is changed according to the difference from the standardized movement pattern. judge.
Note that the sensors illustrated and described in FIG. 11 and their installation locations are examples, and are not limited thereto.

A specific embodiment of Modification 2 will be described in detail below.
In order to grasp the state of mind and body of the driver of a car, a seat type sensor (manufactured by Jepco Co., Ltd.) was installed on the backrest of the driver's seat, and each signal of heartbeat, respiration and body movement was measured simultaneously as vital signs. The detection and analysis of the psychosomatic state was performed by the following procedure.

1. Biological information (the above vital sign) is detected at a sampling frequency of 100 Hz.
2. A low-pass filter is applied to the time-series data of the detected biological information, and components of 15 Hz or higher are cut.
3. Wavelet transform is applied to the signal that has passed through the filter.
4). The Hilbert transform is applied to the wavelet coefficients thus obtained.
5. The following nonlinear analysis is performed on the absolute value x of the signal after the Hilbert transform to obtain three amounts of information (P, F, FS).

（２）データ（絶対値x）についてＤＦＡによるフラクタル解析を施し、揺らぎの大きさF及び揺らぎの傾き（フラクタル指数）FSを求める。 (1) Create a data histogram and fit a scaled gamma distribution curve. The peak position P at that time is obtained. The gamma distribution is expressed by the following equations 4 and 5. Here, b and ν are parameters.

(2) Fractal analysis by DFA is performed on the data (absolute value x), and the magnitude F of fluctuation and the inclination (fractal index) FS of fluctuation are obtained.

FIGS. 13A to 13D show the analysis results of the body motion signal while stopped. Here, the driver as the test subject was a man in the 40s (driving history 22 years), and the target value F ₀ of the driver's fluctuation inclination was set as F ₀ = 1. The wavelet transform used for the analysis is a third-order Daubechies with a scale = 6. As the fluctuation magnitude F, a common logarithm of the fluctuation magnitude at the window size = 4 in DFA was adopted, and as the fluctuation slope FS, the minimum value of the local slope of the DFA plot was adopted.

  The four graphs in FIG. 13 are plotted by connecting time domains corresponding to typical mental and physical states. 13A is a time change of the body motion signal of the subject, FIG. 13B is a time change of the peak position P, FIG. 13C is a time change of the magnitude F of the fluctuation, and FIG. 13D is the fluctuation. This represents the time change of the slope FS.

  In these figures, the peak position P, the fluctuation magnitude F, and the fluctuation slope FS are obtained by analyzing a body movement signal for 12 seconds every 2 seconds. In addition, each of the time regions 1 to 5 is 1: a state in which the person is frustrated and poverty, 2: a quiet state in which the driver is excessively tensioned, 3: driving as a stimulus in order to bring the driver's mind-body state closer to the target value. This corresponds to a state in which the user's favorite music (pops) is being played, 4: a state in which the music is stopped, and a state in which favorite music (pops) different from 5: 3 is being played.

  As shown in FIGS. 13 (a) to 13 (d), in an irritated or nervous state, the inclination FS of the fluctuation tends to take a small value of 0.5 or less, whereas the favorite music is flowing. It can be seen that the fluctuation slope FS is approaching the target value 1. Thus, the adjustment to the appropriate psychosomatic state is achieved by applying the stimulus suitable for the driver.

  FIG. 14 shows the result of plotting the relationship between the peak position P, the fluctuation magnitude F, and the fluctuation slope FS obtained in the above analysis in a three-dimensional space. From this figure, it can be seen that the regions corresponding to the mental and physical states of the frustrated state, the tension and silence state, and the healthy state can be clearly distinguished in the plotted three-dimensional space. Such a determination of the state of mind and body has been difficult from the heartbeat and respiration signals of the driver, so the body motion signal can be regarded as the most appropriate (personalized) mind-body information for the driver.

  Furthermore, in the present embodiment, the peak position P of the gamma distribution can be used in addition to the fractal index FS as an index for grasping the state of mind and body. In this case, the target value is p to 0.5. As is clear from FIG. 13B, the peak position P is P> 1.0 in the inappropriate psychosomatic state (time regions 1, 2, 4), while the healthy psychosomatic state (time regions 3, 5). ), The peak position P is approaching the target value.

<Modification 3>
Furthermore, in said 1st-3rd embodiment, the irritation | stimulation apparatus 9 is not restricted to giving a sound as a stimulus, The image | video and interior color, the transparency (light-shielding property) of a window, fragrance, vibration, temperature, You may give the instruction | indication audio | voice etc. of humidity and the operating method of a moving body. More specifically, for example, as shown in FIG. 12, an incense generating device 9 'is arranged inside the air outlet of an air conditioner, and various fragrances are provided as stimulating modes, and the ones in mind and body are released. May be. Alternatively, a vibration device 9 ″ may be embedded in the seat to apply vibration according to the mind and body state of the driver.

Then, at least one of the stimulus applying devices 9, 9 ′, 9 ″ may be selected to give the driver a stimulus. According to this, the stimulus for changing the health condition For example, some people can easily relieve stress by listening to music, and others can easily relieve stress by the scent of a fragrance. For this reason, in order to increase the control efficiency in controlling the individual's mind-body state to the target state, it is preferable to use a stimulus imparting mode having high action and influence on the mind-body state for each individual. It is possible to select a stimulation mode in consideration of different characteristics for each individual, and it is effective by combining different types of stimulation modes (for example, sound and fragrance). It is possible to act on the mental and physical states of the driver.
It should be noted that the stimulus given to the passenger by this device does not necessarily have a strength that can be clearly recognized by the driver.

<Modification 4>
Moreover, in said 1st-3rd embodiment, you may provide a bell and a lamp as the alerting | reporting apparatus 8, and you may alert | report a driver | operator's mind-body state by alerting | reporting modes, such as a ringing by a bell and blinking by a lamp. For example, when the driver is in the proper state of mind and body, the bell is not ringed or flashed by the lamp. When the state of mind and body is in the stress state, the driver makes a loud sound as the degree of stress increases. Or blinking.

<Modification 5>
Furthermore, the target state setting method of the second embodiment may be combined with the target state setting method of the second embodiment.
That is, in the second embodiment, instead of using a typical target value as a preset target state, the target state calculated according to the mind-body information detected by an individual as in the first embodiment is used. This target state may be used for learning correction. According to this, if a typical target state is set as a control target, the calculation load increases compared to the fact that the calculation load can be reduced, but the mind-body state that the driver should be should be set more appropriately. Can do.

In the first to third embodiments described above, the case of controlling the mind and body state of the driver among the passengers of the moving body as the control target of the apparatus has been described in detail. It is good also as a structure which controls the mind and body state of the pet to do.
In addition, since the present invention is characterized by optimization (personalization) of various means for each passenger, when there are a plurality of passengers or when another person is driving, those who are involved in optimization It is preferable to provide an authentication means for authenticating.
