Before describing the emotion estimation means 11 and the control means 12, an exciting feeling will be described.
The whole emotion (mental state) of a person can be expressed by a two-axis plane (Russell's emotional ring model), which is a horizontal axis of pleasure / discomfort and a vertical axis of active / inactive.
However, in the vehicle V in which a large number of people are traveling, there are a driver, a passenger seat passenger, and a rear seat passenger who have different roles in a limited vehicle interior, and even if the same rear seat passenger is present. In many cases, passengers with different positions may exist.
As a result of the study by the present inventor, in the vehicle V running with a large number of people, the excitement expressed by three axes of emotional identity (x axis), feeling of expectation (y axis), and feeling of achievement (z axis). Has been found to be suitable for emotion determination in the interior of the vehicle V (see FIG. 4).

Emotion identity can be defined as pleasure sympathy, expectation as pleasure existence, and achievement as pleasure acquisition. These identity, expectation, and achievement are difficult to express directly in the Russell's emotional ring model that generalizes human emotions. Therefore, the weighted pleasure value is X, and the weighted activity value is When Y is assumed, the relational expressions of the pleasure X, the activity Y, the identity, the expectation, and the sense of accomplishment are obtained by the following equation based on empirical rules.
Identity = F (X, Y)
Expectation = G (X, Y)
Feeling of achievement = H (X, Y) (1)
Note that F is a three-dimensional relational expression of identity that can be represented by X and Y, G is a three-dimensional relational expression of expectation that can be represented by X and Y, and H is represented by X and Y. It is a three-dimensional relational expression of achievement feeling that can be achieved.

Next, the emotion estimation unit 11 and the control unit 12 will be described.
The emotion estimation means 11 and the control means 12 are constituted by an ECU (Electric Control Unit) 10 in the vehicle V, and have memories such as a CPU (Central Processing Unit), ROM, and RAM.

  The emotion estimation means 11 is configured to be able to estimate the feelings of the passengers P1 to P4 in the estimation section based on the biological information detected by the biological information detection means 2, using a predetermined learning process. Here, for the learning process, for example, an algorithm selected from SVM (Support Vector Machines), a decision tree, a k-nearest neighbor method, or the like is used.

The emotion estimation means 11 detects the degree of pleasure and the degree of discomfort based on images captured by the cameras 22a to 22d. Master images in which the order of facial expressions is determined in descending order are prepared in advance, and the degree of pleasure X is assigned in accordance with the order. Therefore, the images captured by the cameras 22a to 22d are compared with the master images, thereby occupants P1 to P4. The degree of pleasure X is determined.
As shown in FIG. 3A, in addition to the facial expressions of the passengers P1 to P4, the number of gaze direction changes, the number of posture changes, and the pupil diameter are correlated with the degree of pleasure X. The accuracy X of the occupants P1 to P4 is corrected by the number of posture changes and the pupil diameter to set a high accuracy X.

Since the user terminal 23 detects the keyboard input information and the writing input information, the user terminal 23 can correct the pleasure X and the activity Y of the passengers P1 to P4 using the keyboard input information and the writing input information. Specifically, in the keyboard input information, the activity level Y can be estimated by comparing the normal typing error rate with the current typing error rate, and in the written input information, a keyword such as “Bimyo” is used in the message function. The degree of pleasure X can be estimated by “-” (unpleasant word), “pretty good” (quick word), or the like.
In addition, since the driving support device 24 classifies the driving state into a supple driving state, a swaying driving state, and a gentle driving state, it can correct the comfort level X of the occupant P1 based on the classified driving state. By providing an indoor microphone, the words spoken by the passengers P1 to P4 are detected, and the interests of the passengers P1 to P4 are extracted using the detected words, and the pleasure X of the passengers P1 to P4 is obtained. It may be corrected.

The emotion estimation unit 11 detects the degree of activity and inactivity based on the heart rate detected by the user terminal 23. The higher the heart rate, the higher the activity level, and the lower the heart rate, the lower the inactivity level. Therefore, the activity level Y of the passengers P1 to P4 is determined through the heart rate.
As shown in FIG. 3 (b), in addition to the heart rate of the passengers P1 to P4, the respiratory rate, the blood flow velocity, and the skin electrical resistance value are correlated with the activity Y. The activity Y of the occupants P1 to P4 is corrected by the blood flow velocity and the skin electrical resistance value to set a highly accurate activity Y.
The keyboard input frequency also has a correlation with the activity Y, and the activity Y can be estimated indirectly.

  In place of the user terminal 23, an echo measurement unit capable of performing echo measurement of the heart and lungs is provided in each seat where the passengers P1 to P4 are seated, and the heart rate, the respiratory rate, and the blood flow velocity are detected, thereby detecting the passengers P1 to P1. The determination and correction of the activity Y of P4 may be performed. In addition, a skin electrical resistance sensor is disposed at the gripping position of the occupant P1 of the steering wheel 5, and the activity Y of the occupant P1 can be corrected by detecting the skin electrical resistance value.

The emotion estimation means 11 corrects the pleasure X and the activity Y before the break based on the behavior history (walking distance, staying time, product purchase, etc.) of the occupants P1 to P4 input from the user terminal 23 during the break. The map 11a is updated to the latest state so as to reflect the action history of P1 to P4.
The map 11a may be updated by a single communication with the user terminal 23 when the passengers P1 to P4 re-ride.

  The emotion estimation means 11 has a map 11a for storing the transition of emotional changes of the passengers P1 to P4 for each passenger. As shown in FIG. 4, the map 11a shows the feelings of the passengers P1 to P4 expressed by three axes of emotion identity (x axis), expectation (y axis), and sense of accomplishment (z axis). This is expressed in a biaxial plane. In this embodiment, a region where the identity, expectation, and achievement are all high, a region where the so-called excitement is high, is a region W, and a region where the excitement is low is the region V.

The emotion estimation unit 11 calculates the emotion coordinates p1 to p4 of the occupants P1 to P4 by substituting the acquired pleasure X and activity Y of the occupants P1 to P4 into the equation (1), and then the emotion coordinates p1 to p4. Are plotted on the map 11a, and the map 11a is sequentially updated.
The emotion estimation means 11 includes a travel schedule (travel distance, travel time, etc.), types of passengers P1 to P4 (children, guests who need hospitality, passengers who have physiological demands, etc.) through communication with the user terminal 23. ) Is input, various additional information is linked to the emotion coordinates p1 to p4.

Next, the control means 12 will be described.
The control means 12 is configured to be able to execute the normal mode and the priority mode having the first overall control based on the presence or absence of a priority occupant that preferentially corresponds to other occupants.
Further, in the normal mode, the control means 12 performs second and third overall control for guiding the feelings of the occupants P1 to P4 in a certain direction, and the first control for guiding the feeling of the specific occupant among the occupants P1 to P4 in a certain direction. 1st-3rd individual control is comprised so that execution is possible. Further, the control means 12 is configured to restrict the control of the emotion improving means 3 that brings the feelings of the passengers P1 to P4 approaching each other when a preset restriction condition is satisfied.
As shown in FIG. 2, the control means 12 includes a priority occupant determination unit 13, an occupant emotion comparison unit 14, a storage unit 15, and an execution unit 16.

First, the priority occupant determination unit 13 will be described.
The priority occupant determination unit 13 determines a priority occupant whose emotion should be improved in preference to other occupants among the occupants P1 to P4. The priority occupant determination unit 13 determines an occupant having a physiological request as a first priority occupant based on the additional information of the map 11a. A passenger whose emotions have deteriorated due to poor physical condition (car sickness, constipation, etc.) corresponds to the first priority passenger.
Therefore, the first priority occupant whose emotions have deteriorated from the physical condition may directly determine the physical condition of the occupant by comparing the actual biological measurement values such as the heart rate and the movement of the facial expression with a predetermined criterion. good.
Further, the priority occupant determination unit 13 determines, as the second priority occupant, an occupant that the occupant P1 needs to give priority over other occupants based on the additional information of the map 11a. Relatives, friends, business customers, etc. who have visited after a long time correspond to second priority passengers.

Next, the occupant emotion comparison unit 14 will be described.
The occupant emotion comparison unit 14 compares whether or not the estimated emotions of the occupants P1 to P4 are close to each other. It is determined whether or not the emotion coordinates p2 to p4 of the occupants P2 to P4 exist within the concentric region A of a constant distance from the emotion coordinates p1 of the occupant P1 on the map 11a.
If the emotion coordinates p2 to p4 of the occupants P2 to P4 exist in the region A, the occupants P2 to P4 have emotions (similar emotions) that are substantially the same as or close to the occupant P1, and the occupants outside the region A are occupants P1. Have different emotions (dissimilar emotions). The fixed distance for forming the region A is set in advance by experiments or the like.

Next, the execution unit 16 will be described.
The execution unit 16 controls the emotion improving means 3 so as to improve the emotion of the occupant whose emotion has basically deteriorated while performing feedback based on the map 11a.
When the estimated emotions of the occupants P1 to P4 are separated from each other, the execution unit 16 makes the emotions of the occupants P1 to P4 approach each other, and when the emotions of the plurality of occupants deteriorate, The emotion improving means 3 is controlled so as to be guided in the same direction.
Further, the execution unit 16 guides a plurality of occupant emotions in a certain direction when a preset restriction condition (specifically, the scheduled travel time is short and the occupant emotions deteriorate and nighttime) is satisfied. The control of the emotion improving means 3 is limited.

The execution unit 16 is configured to be capable of executing first to third overall control mainly using the common sense induction unit and the individual sense induction unit, and first to third individual control mainly using the individual sense induction unit. .
The first overall control is based on the map 11a so as to improve the feeling of the first or second priority occupant in a pleasant direction in preference to other occupants when the first or second priority occupant is on board. Thus, the emotion improving means 3 is controlled. In the first overall control, in addition to the individual sense guidance unit 3b corresponding to the first or second priority occupant, the common sense guidance unit 3a including the driving operation guidance unit 3c is controlled.

In the second overall control, when the occupants P1 to P4 are in a similar emotion state (the emotion coordinates p2 to p4 are present in the area A) and the occupants P1 to P4 are not in good emotion, the occupant is in a state in which the similar emotion state is maintained. The emotion improving means 3 is controlled based on the map 11a so that the emotions P1 to P4 shift in the direction of the region W including the pleasant state. In the second overall control, a common sense guidance unit 3a including a driving motion guidance unit 3c and an individual sense guidance unit 3b are used.
Further, in the third overall control, when there is an occupant separated from the emotion of the occupant P1 and the emotions of a plurality of occupants deteriorate (a plurality of emotion coordinates p1 to p4 having negative coordinates), the occupants P1 to P4 The emotion improving means 3 is controlled based on the map 11a so as to make the emotion approach. In the third overall control, the common sensory guidance part 3a excluding the driving action guidance part 3c is mainly used, and the individual sensory guidance part 3b is used as an auxiliary. Then, the emotions of the passengers P1 to P4 that are guided to approach are guided to shift to a desired region including the region W while maintaining a similar emotional state.

In the first individual control, when the occupant P3 or the occupant P4 is in an emotionally deteriorated state and travels at night, the occupant P3 or P4 is left in the state or the feeling of the occupants P1 and P2 is improved in a pleasant direction with the activation suppressed. Thus, the emotion improvement means 3 is controlled based on the map 11a. In the first individual control, the driving operation guiding unit 3c and the individual sense guiding unit 3b are used.
The second individual control is based on the map 11a so that when there is an occupant that is separated from the emotion of the occupant P1 and the emotion of the occupant P1 is good, the emotion of the occupant whose emotion is deteriorated is transferred into the region W. It controls the emotion improvement means 3. In the second individual control, only the individual sensory guidance unit 3b is used.
The third individual control is such that when there is an occupant separated from the emotion of the occupant P1 and there is no sudden change of the emotion in the occupant P1, the map is improved so that the emotions of the occupants P1 to P4 are approached while improving in a pleasant direction. The emotion improvement means 3 is controlled based on 11a. In the third individual control, the driving operation guiding unit 3c and the individual sense guiding unit 3b are mainly used.

Next, the control processing of the occupant emotion response control apparatus 1 will be described based on the flowcharts of FIGS. 5 to 7 and FIGS. 8 to 11. Si (i = 1, 2,...) Indicates a step for each process.
First, as shown in FIG. 5, in the occupant emotion correspondence control apparatus 1, the output from the biological information detection means 2 is input (S1), and the process proceeds to S2.

In S2, it is determined whether or not the occupants P1 to P4 get off the vehicle V and perform different actions, for example, whether or not they have taken a rest in a highway service area or the like.
As a result of the determination in S2, when the occupants P1 to P4 take a break, correction values for the pleasantness X and the activity Y before the break are set according to the behavior history of each of the occupants P1 to P4 during the break (S3), and S4 Transition.
The emotion estimation means 11 estimates the cause of transition of emotional changes of the passengers P1 to P4 based on the behavior history during the break. For example, if a passenger moves to a predetermined store while getting off and there is a transaction for purchasing a product related to the destination, a part of the driving purpose has been achieved, so the degree of pleasure (expectation) decreases after purchase. In some cases, when the passenger gets off, the toilet is crowded and the departure time has not been completed, and the occupant's physical condition deteriorates, and the emotion can suddenly shift to an inactive state. Since the occupant P1 is paying attention to the occupants P2 to P4 during traveling, the occupant P1 generally understands the feelings of the occupants P2 to P4 until the passenger gets off to take a break in the service area of the highway.
However, since the passenger P1 does not see the behaviors and behaviors of the passengers P2 to P4 during the break, and does not know the emotional changes during the break, the passenger P1 rides for a while after the passengers P2 to P4 get on and restart. The state of P2-P4 is asked and the feelings of passengers P2-P4 are grasped again.
With this control, for the occupant P1, the vehicle V side performs a predetermined driving operation with respect to the occupant P1 unconsciously based on the map 11a reflecting the latest feelings of the occupants P2 to P4 after the re-boarding. Therefore, the attention load on the passengers P2 to P4 is reduced. In addition, for passengers P2 to P4, each passenger's request can be made without telling passenger P1 the event during the break (for example, the toilet could not be crowded, or the patient became sleepy as a result of having lunch at the stall). The feelings are improved because the requirements are fulfilled by processing according to (for example, the navigation system sets the service area of the shortest distance as a stopover point, stabilizes the vehicle behavior while ensuring quietness by the active noise canceller function, etc.) The
As a result of the determination in S2, when the passengers P1 to P4 are not taking a break with getting off, the process proceeds to S4.

In S4, the feelings of the passengers P1 to P4 are estimated using a predetermined learning process.
The passengers P1 to P4 are calculated by calculating the pleasantness X and the activity Y of the passengers P1 to P4 based on various biological information and a correction value based on the action history, and substituting these pleasures X and the activity Y into the equation (1). The emotion coordinates p1 to p4 of .about.P4 are calculated.
Additional information such as the travel schedule and the types of the passengers P1 to P4 is associated with the emotion coordinates p1 to p4, respectively, and the process proceeds to S5.

In S5, the previous map 11a (see FIG. 4) is updated based on the emotion coordinates p1 to p4, and the process proceeds to S6. In S6, the priority occupant is determined based on the emotion coordinates p1 to p4 and the additional information attached to the emotion coordinates p1 to p4 of the occupants P1 to P4.
In S6, for example, a physiological request such as car sickness or constipation is determined for the occupants P1 to P4 based on the emotion coordinates p1 to p4. If there is an occupant who has generated a physiological request, the occupant is given first priority. Decide on the crew. Also, depending on the type of the passengers P1 to P4, for example, when there is an occupant that another occupant (especially the occupant P1) needs to entertain, such as a relative who has visited after a long time or a customer on the job, the occupant Decide to be the second priority occupant.

Next, it transfers to S7 and it is determined whether a 1st priority crew member or a 2nd priority crew member exists.
As a result of the determination in S7, when the first priority occupant or the second priority occupant exists, the priority mode is executed (S8). If the result of determination in S7 is that there is no first priority occupant or second priority occupant, the normal mode is executed (S9). These processes are executed at regular intervals from the time when the ignition is turned on until the travel schedule is completed and the ignition is turned off.

Next, the priority mode process will be described with reference to the flowchart of FIG.
In the priority mode, when both the first priority occupant and the second priority occupant are present, the first priority occupant is given priority over the second priority occupant, and the feeling (physical condition) of the first priority occupant is improved. The emotion improvement of the second priority occupant is executed.

In S11, it is determined whether or not the first priority occupant is generated.
When the first priority occupant is generated as a result of the determination in S11, the process proceeds to S12 and the first overall control is executed. For example, when the occupant P3 is estimated to have an emotional deterioration due to car sickness, the stimulus acting on the occupant P3 is reduced based on the map 11a so that the emotion of the occupant P3 is improved.

  Specifically, the lighting device 33 corresponding to the occupant P3 as the individual sensation guiding unit 3b shortens the wavelength of the illumination light (blue system) and decreases the amplitude (darkens), and the individual speaker 38 corresponding to the occupant P3. However, the sound of the speaker 32 and the road noise are muffled in a pseudo manner, and the seat back monitor 39 corresponding to the occupant P3 projects a calm scenery or the like. Further, as the common sensation guiding unit 3a, the air conditioner 31 adjusts the in-vehicle temperature to a temperature suitable for the occupant P3 based on the map 11a, and the speaker 32 selects a calming song for the occupant P3 to reduce the volume.

Further, as the driving operation guiding portion 3c, the window frame varying device 35 suppresses the actual vehicle speed of the vehicle V by widening the field of view of the front window glass and increasing the perceived speed of the occupant P1, and the variable steering device 36 reduces the steering resistance. The vibration of the vehicle V is suppressed to increase, and the monitor 37 proposes a break and the nearest service area at an early point.
As described above, the stimulus acting on the occupant P3 is reduced, the emotion of the occupant P3 can be improved, and the attention load on the occupant P1 is reduced.
In addition, when the occupant P1 feels that he / she wants to steer quickly at high speed, the occupant P1 feels that the driving (perceived speed, perceived steering sensation) can be realized as desired by the occupant P1, and thus the occupant P1. And other passengers, in particular, the feelings of the passenger P3 whose emotions have deteriorated.

As a result of the determination in S11, if the first priority occupant has not occurred, the process proceeds to S13.
In S13, it is determined whether or not the feeling of the second priority occupant has deteriorated based on the map 11a. In the following, the emotional deterioration is a state in which the value of the current emotion coordinate is shifted in a negative direction from the previous emotional coordinate in terms of identity, expectation, and achievement.
As a result of the determination in S13, if the emotion of the second priority occupant has deteriorated, the process proceeds to S12 to execute the first overall control. Basically, the individual sensation guidance unit 3b, the common sensation guidance unit 3a, and the driving operation are performed so that the emotion coordinates of the second priority occupant move in the positive direction from the previous emotion coordinates. The guide part 3c is operated. In addition, when the second priority occupant has an emotional deterioration due to physical condition, the same first overall control as the first priority occupant is executed.
For example, it is assumed that the occupant P3 is a relative child corresponding to the second priority occupant and the vehicle speed range of the occupant P1 is higher than the normal vehicle speed range of the occupant P3 parent.
In this case, although the passenger P3 feels fear, he / she refrains from saying that he / she wants the passenger P1 to decelerate the vehicle speed, and his feelings gradually worsen. When such an emotional deterioration of the occupant P3 (second priority occupant) is detected, the occupant P1 unconsciously reduces the vehicle speed by the window frame shielding operation by the variable window frame device 35. As a result, the emotion of the occupant P3 is improved. When guided in the direction, the window frame shielding operation is continued.
As for the passenger P1, the passenger P3 can be relieved while maintaining good feelings without having to feel unpleasant because his / her driving is corrected (for example, “run more slowly!”).
As a result of the determination in S13, if the emotion of the second priority occupant has not deteriorated, the process proceeds to S9 and the normal mode is executed.

Next, processing in the normal mode will be described based on the flowchart of FIG.
In the normal mode, basically, the second and third overall controls and the first to third individual controls are executed so that the passengers P1 to P4 are in a similar emotional state and the passengers P1 to P4 can feel the excitement. To do.

In S21, it is determined whether or not the current scheduled travel time is a long time.
As a result of the determination in S21, if the estimated traveling time is a long time, for example, 1 hour or more, the process proceeds to S22. As a result of the determination in S21, if the scheduled traveling time is short, sufficient time for guiding the feelings of the passengers P1 to P4 in the improvement direction cannot be secured, and the process returns to S1.
When the scheduled travel time is short, even if each control is executed, it does not lead to improving the feelings of the passengers P1 to P4 or ensuring the identity of the passengers, especially when the planned travel time is short. When the operation guiding portion 3c is activated, only a sense of incongruity is given to the passenger P1. Therefore, emotion improvement control is limited to prevent the above-mentioned problems.
Here, whether or not the scheduled traveling time is long can be referred to, for example, the arrival time to the destination set in the navigation system. If you are traveling for a short time, such as picking up at a nearby shopping mall or the nearest station, this is a known destination for the occupant P1, and the destination is not set. The execution of this control can be omitted. Further, the length of the boarding time may be determined with reference to the scheduler of the user terminal 23.
In S22, it is determined whether or not the emotion coordinates p2 to p4 are within the region A.
If the emotion coordinates p2 to p4 are within the region A as a result of the determination in S22, the occupants P1 to P4 are in a similar emotion state, and the process proceeds to S23.

In S23, it is determined whether or not the passenger P1 has a previous emotional change.
The emotion of the occupant P1 who is driving is affected more quickly and greatly than the occupants P2 to P4 by the influence from the surrounding environment including the traffic situation, so the emotion change speed is faster than that of the occupants P2 to P4.
For the emotional change immediately before the occupant P1, the change rate of the emotion coordinate p1 is detected, and when the change rate of the emotion coordinate p1 is greater than or equal to a predetermined value in the positive direction (or negative direction), it is determined that there is an immediately previous emotion change. .
As a result of the determination in S23, if there is a previous emotional change in the occupant P1, as shown in FIG.
If the result of determination in S23 is that there is no previous emotional change in the occupant P1, the process proceeds to S25.

In S24, the surrounding situation of the vehicle V imaged and temporarily recorded by the outside camera 21 is reproduced on the monitor 37 and the seat back monitor 39, and the process proceeds to S25.
For example, when the occupant P1 is impressed by the beautiful scenery ahead, the same object is imposed without forcing the occupant P1 to “look at that scenery, that scenery” and point to the occupants P2 to P4 to guide the line of sight. Therefore, the passengers P1 to P4 can generate the emotion of the passengers P1, so that the passenger P1 can improve the identity of the emotion by obtaining sympathy with the passengers P2 to P4, and can concentrate on driving.
Further, even when the occupant P1 feels anger due to a sudden interruption vehicle or the like, the occupant P1 can concentrate on driving by obtaining sympathy with the occupants P2 to P4.
When an abrupt interruption occurs, the occupant P1 is able to resolve the anger if he / she is driving alone, but the anger cannot be resolved if the occupants P2 to P4 of the passenger are present. Therefore, it can be considered that driving will be adversely affected. In this control, the passenger P1 understands the situation to the passengers P2 to P4 because the passengers P2 to P4 can speak (for example, “That car is really violent”, “dangerous”, etc.) By recognizing, you can ease your anger, so you can concentrate on driving.
In addition, the passengers P2 to P4 can be linked to the speed and direction of the emotional change of the passenger P1, the atmosphere inside the vehicle is excited, and a sense of solidarity among the passengers including the passenger P1 is born and the behavior at the destination is reached. The situation can be improved as a whole vehicle.
If an animation related to a reproduced event (for example, a traffic event in the case of an interrupted vehicle) is stored in advance, it may be reproduced after the captured image. Accordingly, whether or not the animation can be reproduced can be set in advance.
Further, instead of the actual video of the interrupting vehicle, an animation in which the interrupting vehicle is deformed in a villain style may be reproduced.

In S25, it is determined whether or not the emotion coordinate p1 is within the region W.
As a result of the determination in S25, when the emotion coordinates p1 are in the region W, the passengers P1 to P4 in the region A have a feeling of excitement, and therefore, the process returns to S1 without taking action for improving emotions.
As a result of the determination in S25, when the emotion coordinates p1 are outside the region W, the passengers P1 to P4 are not feeling the excitement although they are in a similar emotion state, so the second overall control is executed (S26), S1 Return to

In S26, the second overall control is executed.
Specifically, all the illumination devices 33 lengthen the wavelength of the illumination light (red system) and increase the amplitude (brighter), and all the individual speakers 38 mute the road noise in a pseudo manner, and monitor 37 And the seat back monitor 39 displays destination information and the like that the passengers P1 to P4 have in common. In addition, the air conditioner 31 adjusts the vehicle interior temperature based on the map 11a, and the speaker 32 selects a song that the passengers P1 to P4 like in common or enhances emotions and increases the volume.
Further, the window frame variable device 35 increases the actual vehicle speed of the vehicle V by narrowing the field of view of the front window glass and lowering the perceived speed of the occupant P1, and the variable steering device 36 reduces the steering resistance to reduce the vehicle V. The feeling of running is generated.
As described above, the identity, expectation, and achievement of the occupants P1 to P4 can be improved, and the emotions of the occupants P1 to P4 are improved while maintaining the similar emotional state.
For example, in a day trip to a sightseeing spot, although all crew members are excited immediately after departure, a situation may occur in which the indoor atmosphere becomes sluggish after a while on the expressway.
By the second overall control, the feelings of the occupants P1 to P4 who are sluggish can be directed in the improvement direction while maintaining the similar emotional state.

As a result of the determination in S22, if any of the emotion coordinates p2 to p4 is outside the region A, since the occupant's emotion is separated from the occupant P1's emotion among the occupants P2 to P4, the process proceeds to S27.
In S27, it is determined whether or not the occupant P3 or P4 is in an emotional deterioration state.
As a result of the determination in S27, when the occupant P3 or P4 is in an emotional deterioration state, the process proceeds to S28, and it is determined whether or not it is currently nighttime.
As a result of the determination in S28, if the vehicle is traveling at night, the process proceeds to S29. If the vehicle is not traveling at night, the process proceeds to S30.

In S29, the first individual control is executed.
As shown in FIG. 9, for example, when the occupants P3 and P4 are both in an emotional deterioration state (any one of the emotion coordinates p3 and p4 has the same value, expectation, or feeling of achievement), the occupants P3 and P4 Since it is estimated that the patient is sleepy or tired, the front seat occupants P1 and P2 and the rear seat occupants P3 and P4 in an aggravated state are separated.
Specifically, the illumination device 33 corresponding to the passengers P3 and P4 shortens the wavelength of the illumination light and reduces the amplitude, and the illumination device 33 corresponding to the passengers P1 and P2 increases the wavelength of the illumination light. The individual speakers 38 corresponding to the passengers P3 and P4 increase the amplitude and mute the sound and road noise of the speakers 32, and the individual speakers 38 corresponding to the passengers P1 and P2 simulate the sounds of the speakers 32. The reproduction of the seat back monitor 39 corresponding to the passengers P3 and P4 is stopped. Further, the speaker 32 reduces the volume. Furthermore, the window frame variable device 35 suppresses the actual vehicle speed of the vehicle V by widening the field of view of the front window glass and increasing the perceived speed of the occupant P1, and the variable steering device 36 increases the steering resistance and shakes the vehicle V. Suppress.
As described above, by maintaining the dissimilar emotional state of the occupants P1 to P4, the occupants P3 and P4 can sleep and rest, while the occupants P1 and P2 can improve their emotions and ensure high driving awareness. Can do. For the passengers P3 and P4, the emotion improvement control for the passengers P3 and P4 may be stopped and left alone, or may be separated on a monotonous road in addition to the night.
As an example, on the way home for a day trip to a sightseeing spot, it is night and the rear seat passengers P3 and P4 are sleepy. In this case, it is possible to sleep without forcibly stimulating the passengers P3 and P4. About the passenger | crew P1, the caring load for carrying out a gentle driving | operation with respect to sleeping P3, P4 can be reduced.

As a result of the determination in S27, when the occupant P3 or P4 is not in an emotionally deteriorated state, the process proceeds to S30, and it is determined whether or not the emotion coordinate p1 is within the region W.
As a result of the determination in S30, when the emotion coordinate p1 is within the region W, the occupant P1 is in a good state where he can feel the excitement, but any of the occupants P2 to P4 cannot feel the excitement, so the second individual control Is executed (S31), and the process returns to S1.

In S31, the second individual control is executed.
As shown in FIG. 10, for example, when the emotion coordinates p1 is within the region W and the emotion coordinates p2 to p4 are outside the region W, the individual sense guidance is performed so that the emotion coordinates p2 to p4 are moved into the region W based on the map 11a. The unit 3b is controlled. As a result, the feelings of the occupants whose emotions are worsening among the occupants P2 to P4 are improved while maintaining the good feelings of the occupant P1, and the feelings of the occupants P1 to P4 are induced to a similar emotional state.
As an example, on the way to a day trip to a sightseeing spot, the crew P1 felt a sense of accomplishment in delivering the crew P2 to P4 to the sightseeing spot and expected to return home without any trouble and finish this drive successfully. The passengers P2 to P4 have no purpose after visiting the sightseeing spot, and some passengers have a feeling of loss due to disappointment of the sightseeing spot depending on the passenger. In such a case, when the special dishes of each service area on the return expressway are displayed on each monitor, or when the emotion values of all the occupants P1 to P4 rise in the outward trip (emotion coordinates p1 to p4 move into the area W) ), The passengers P2 to P4 can be activated by reproducing the feeling of excitement.

As a result of the determination in S30, if the emotion coordinate p1 is outside the region W, the passenger P1 is not feeling the excitement and is in a dissimilar emotion state, so the process proceeds to S32.
In S32, it is determined whether or not the feeling of the passenger P1 has deteriorated immediately before and any of the passengers P2 to P4 has deteriorated.
As a result of the determination in S32, when the feeling of the occupant P1 has deteriorated immediately before and any of the occupants P2 to P4 has deteriorated, the third overall control is executed (S33), and the process returns to S1. .

In S33, the third overall control is executed.
As shown in FIG. 11, for example, when all the emotions of the passengers P1 to P4 are distributed in the emotion worsening side region and the passenger P1 has a previous emotional change, in order to stabilize the emotion of the passenger P1 It is controlled to an in-vehicle environment that can be perceived in common by the passengers P1 to P4.

Specifically, the illumination device 33 shortens the wavelength of the illumination light and decreases the amplitude, and the individual speaker 38 artificially amplifies road noise. Further, the air conditioner 31 reduces the in-vehicle temperature based on the map 11a.
As described above, in order to intentionally induce the feelings of the passengers P1 to P4 to the same emotional area by deteriorating the in-vehicle environment with the guidance medium (illuminance, sound, temperature) that can be perceived in common by the passengers P1 to P4, The consciousness of P4 can be directed to a specific event, and the occupant P1 can concentrate on driving while sympathizing with the occupants P2 to P4. When there is an occupant whose emotion coordinates are located in the region V, the in-vehicle environment is improved by a guidance medium that the occupants P1 to P4 can perceive in common, and the emotions of the occupants P1 to P4 are intentionally guided to the same emotion region. In addition, it is possible to continuously induce the feelings of the passengers P1 to P4 to the area W.
As an example, on the way back to a sightseeing spot, the occupants P3 and P4 start to argue because they are trivial, the arbitration of the occupant P2 does not work, and the occupant P1 cannot concentrate on driving. In such a case, cold air blows out from the air outlet of the air conditioner 31 when the blower fan is fully opened, and road noise is generated to such an extent that a voice of a dispute cannot be heard for a moment in the hearing of the passengers P1 to P4. The passengers P3 and P4 are strongly stimulated by the common unpleasant experience and returned to me, and one of them speaks out for reconciliation such as “something is cold” and can end the dispute. Further, a similar effect can be expected by displaying an animation of a character deformed of an angry animal on the seatback monitor 39 and objectively viewing itself. With this control, the occupant P1 can concentrate on driving again without the burden of enduring utterances to stop the dispute.
On the other hand, the same effect can be obtained by a common pleasant experience (for example, showing an image of a delicious dish before lunch), but the common unpleasant experience has a stronger perceptual stimulus.

As a result of the determination in S32, when the feeling of the occupant P1 has deteriorated immediately before and any of the occupants P2 to P4 has not deteriorated, at least the feeling of the occupant P1 is not good, so the third individual control is performed. Execute (S34) and return to S1.
In S34, the third individual control is executed.
For example, when all of the emotions of the passengers P1 to P3 other than the passenger P4 are present in the emotion deterioration region, the emotions of the passengers P1 to P3 are improved based on the map 11a.
Specifically, the lighting device 33 corresponding to the passengers P1 to P3 increases the wavelength of the illumination light and increases the amplitude, and the individual speaker 38 corresponding to the passengers P1 to P3 mutes the road noise in a pseudo manner. . Further, the window frame variable device 35 increases the actual vehicle speed of the vehicle V by narrowing the field of view of the front window glass and lowering the perceived speed of the occupant P1, and the variable steering device 36 reduces the steering resistance to reduce the vehicle V. The feeling of running is generated.
As described above, the identity, expectation, and achievement of the passengers P1 to P3 can be improved, and the feelings of the passengers P1 to P3 are improved.
As a specific example 1, since there are many cars on the highway heading to the sightseeing spot, especially in the traveling lane, the front is clogged, and it can only cruise at a vehicle speed lower than the vehicle speed range preferred by the occupant P1, and the inter-vehicle distance cannot be secured. Is when you feel stress. Although it is possible to change the lane to the overtaking lane, the overtaking lane has a higher vehicle speed than the vehicle speed range preferred by the occupant P1 and may be beaten. The occupant P1 has a desire to brag about the high power performance of the vehicle V, but the occupant P4 may be afraid of speed, so it is better to maintain a low vehicle speed. Thinking and restraining desire. The occupant P1 is exposed to a load that constantly considers driving safety, self-desires, and occupant's emotions, and emotions may temporarily worsen when the front is blocked by a large vehicle.
As a specific example 2, on the mountain sightseeing road, the occupant P1 has a desire to enjoy the running performance of the vehicle V on the winding road and a duty to travel at a low speed so that the occupants P2 to P4 can appreciate the spectacular view. is there. In such a case, the occupant P1 is exposed to a load that constantly considers what speed to travel while inferring the feelings of the occupants P2 to P4. When the number of succeeding vehicles increases, the emotion may be temporarily deteriorated depending on whether the speed should be increased or overtaken.
In any case, when other occupants P2 to P4 are present in the emotional deterioration area, it is determined that the occupant P1 is stressed at the low vehicle speed as in the case of the occupant P1, and the decision is made to increase the vehicle speed to the occupant P1 as described above. Control to prompt. The occupant P1 is released from the load that considers the emotions of the occupants P2 to P4, and the emotions of the other occupants P2 to P4 can also shift in the improvement direction. If the feelings of other occupants P2 to P4 are present in a good area, it is determined that the current traveling speed has a sense of security, and in order to maintain the current vehicle speed, the field of view of the occupant P1 is widened. The stress of the passenger P1 is eliminated by increasing the perception speed.

Next, the operation and effect of the occupant emotion response control apparatus 1 will be described.
According to this occupant emotion correspondence control apparatus 1, since the emotion improvement means 3 includes a plurality of common sensory guidance sections 3a that can output a guidance medium that can be commonly perceived by the occupants P1 to P4, the occupants P1 to P4 are in common. A vehicle cabin environment that can be perceived by the user can be intentionally formed.
When the feelings of the occupants P1 to P4 are deteriorated, the control means 12 operates the at least one common sense guiding unit 3a to induce the feelings of the occupants P1 to P4 in the same direction. Can be shared.

  Since the emotion estimation means 11 has a map 11a for storing the change of emotion changes of the passengers P1 to P4 for each passenger P1 to P4, and the control means 12 controls the emotion improvement means 3 based on the map 11a, the passengers P1 to P4 It is possible to easily and accurately track the transition of the emotion change for each, and to control the emotion improving means 3 with a simple configuration.

  When the feelings of the occupants P1 to P4 estimated by the emotion estimation means 11 are separated from each other, the control means 12 controls the emotion improvement means 3 so as to bring the feelings of the occupants P1 to P4 closer to each other. The emotion of P4 can be shifted to the same emotion area, and empathy can be easily generated.

  When the feeling of the occupant P1 deteriorates, the control means 12 guides the common sensation guiding unit 3a in the direction of worsening or improving the feeling, so that the sameness of emotion can be secured between the occupants P1 to P4, and the occupant P1 can drive. You can concentrate.

Next, a modified example in which the embodiment is partially changed will be described.
1) In the above-described embodiment, an example in which there are three passengers has been described. However, there may be one passenger or three or more passengers depending on the allowable number of vehicles.

2) In the above embodiment, an example of controlling a plurality of types of emotion improvement means in the priority mode and the normal mode has been described. However, it is sufficient that at least the passenger's emotion can be guided in a pleasant direction, and if possible, only a specific device is used. May be activated. It is also possible to selectively select an effective device according to the type and situation of the occupant, and the device to be operated may be changed according to the passenger's preference.

3] In the above embodiment, an example has been described in which an emotional deterioration is compared with the previous emotional coordinate, and when any one of identity, expectation, and achievement shifts in a negative direction. Emotion deterioration may be determined when any one of identity, expectation, and achievement shifts in a negative direction by a predetermined amount or more. Moreover, the determination method of emotion deterioration may be changed according to factors depending on the passenger.
Specifically, the driver's emotional deterioration determination is performed when the feeling of achievement shifts in the negative direction, or when the identity or expectation shifts in the negative direction by a predetermined amount or more. It is also possible to determine the emotional deterioration when the identity or expectation shifts in the negative direction, or when the sense of achievement shifts in the negative direction by a predetermined amount or more.

4) In addition, those skilled in the art can implement the present invention with various modifications added without departing from the spirit of the present invention, and the present invention includes such modifications. is there.
