Description

The present technology relates to an information processing device, an information processing method, and a program, and more particularly to an information processing device, an information processing method, and a program suitable for use in providing driving support for a moving object.

Conventionally, the biometric information of the driver has been used to detect the driving state of the driver.

For example, the driver's skin impedance measurement value is corrected by the correction data based on the measured value of the driver's skin impedance when the eyes are closed at rest and the average value of the measured value during normal activity, and the measured value of the driver's skin impedance is corrected based on the corrected value. It has been proposed to determine the degree of arousal of the driver (see, for example, Patent Document 1).

For example, the biometric data measured by the biosensor of the vehicle is transmitted to the data processing device via the mobile terminal installed in the charger in the vehicle and the public network line, and the data processing device transmits the received biometric data to the driver. It has been proposed to transmit the data to the mobile terminal of the above (see, for example, Patent Document 2).

<Driving support processing>
Next, the driving support process executed by the server 13 will be described with reference to the flowcharts of FIGS. 5 and 6.

Hereinafter, the processing mainly for one specific user (hereinafter referred to as a attention user) will be mainly described, but in reality, the processing for other users other than the attention user is performed in parallel.

In step S1, the server 13 starts the estimation process of the state of the user (attention user) during non-operation. Specifically, for example, the following processing is started.

The state estimation unit 152 acquires data related to the state of the attention user from the data (for example, inertial data, environment data, biometric data, input data, etc.) received by the communication unit 151 from the user terminal unit 11 of the attention user. .. The state estimation unit 152 stores each data in the storage unit 162 together with the acquired time. As a result, the status data log of the attention user is updated.

The state data log of the attention user may include not only data regarding the state of the attention user itself but also data regarding the surrounding state of the attention user.

The state estimation unit 152 estimates the current state of the attention user using the state estimation model of the attention user stored in the storage unit 162 based on the state data log of the attention user within the latest predetermined period. .. For example, the state estimation unit 152 estimates the current biological state, behavior, and emotion of the attention user as the current state of the attention user.

For example, as illustrated in FIG. 7, the state estimation unit 152 sets the biological state and behavior of the attention user at predetermined time frames based on the time-series change of the sensor data group indicating the state of the attention user. To estimate. For example, various biological states of the attention user such as concentration, alertness, fatigue, stress, tension, and intensity of exercise are estimated based on the heart rate and sweating amount of the attention user. For example, the type of behavior of the attention user (for example, stationary, walking, running, cycling, going up and down stairs, eating, sleeping, etc.) is estimated based on the acceleration and angular velocity of the attention user, the ambient air pressure, and the like. ..

Further, for example, the state estimation unit 152 estimates the movement distance, movement speed, action range, etc. of the attention user based on the position data, acceleration, and the like of the attention user.

Further, the state estimation unit 152 estimates the emotion of the attention user based on the biological data of the attention user, the estimation result of the biological state of the attention user, and the like. For example, the state estimation unit 152 estimates the degree of emotions, excitement, impatience, anxiety, and the like of the attention user.

It should be noted that the biological states and emotions of the attention user are not necessarily all clearly separated, and some of them overlap. For example, the degree of excitement can be either the biological state or emotion of the user of interest.

Further, any method can be adopted as the method for estimating the user's state. Further, the type of user state to be estimated is not limited to the above-mentioned example, and can be added or deleted as needed.

The state estimation unit 152 stores the estimated state of the attention user in the storage unit 162 together with the estimated time. As a result, the estimated state history of the attention user is updated.

In addition, for example, as illustrated in FIG. 7, the estimated state history is given to data in which numerical values for each frame are arranged in chronological order such as alertness, or for each frame such as an action (type of action). Includes data in which labels are arranged in chronological order.

In step S2, the learning unit 160 determines whether or not to learn the standard state pattern (standard state pattern) of the user (attention user). For example, in the learning of the standard state pattern of the attention user, when the attention user starts using the information processing system 10, the amount of data in the estimated state history of the attention user increases by a predetermined amount or more every time a predetermined time elapses. It is executed at a predetermined timing such as every time. Then, when the learning unit 160 is at the timing of learning the standard state pattern of the attention user, the learning unit 160 determines that the standard state pattern of the attention user is to be learned, and the process proceeds to step S3.

In step S3, the learning unit 160 learns a standard state pattern (standard state pattern) of the user (attention user). For example, the learning unit 160, as illustrated in FIG. 8, has a standard state pattern of the attention user based on the estimated state history within the most recent relatively long period (for example, monthly, yearly) of the attention user. To learn.

For example, the learning unit 160 calculates the average and variance for each period of a predetermined time (for example, 1 minute, 10 minutes, 30 minutes, or 1 hour) of each of the following items as a standard state pattern of the user of interest. By doing so, a transition pattern showing a standard transition for a predetermined period (for example, one day) of each item is learned. For example, one day of concentration, alertness, fatigue, stress, tension, exercise intensity, heartbeat, sweating amount, exercise amount, emotional degree, excitement, impatience, anxiety, etc. of the attention user. The standard transition pattern of is learned.

Further, for example, the learning unit 160 calculates the average and variance of each of the following items for each day (every day of the week) as a standard state pattern of the user of interest for a predetermined period of each item (for example, one week). ) Learn the standard transition pattern. For example, standard transition for one week such as sleep time, wake-up time, bedtime, amount of exercise, movement range, number of meals, meal time, meal time zone, driving time, driving time zone, commuting time zone, commuting time zone, etc. The pattern is learned.

Further, the learning unit 160, as a comparison target of the standard state patterns of the attention users, is an average standard state pattern (user set state pattern) in the user set based on the estimated state history of each user in the predetermined user set. To learn.

Here, the user set may include all users of the information processing system 10, or may include only some users. In the latter case, for example, it may be a user set consisting of users similar to the user of interest. Here, the user similar to the attention user is, for example, a user having similar attributes (for example, age, gender, occupation, address, etc.), behavior pattern, preference, etc. to the attention user. In addition, the user set may or may not include the user of interest.

For example, as illustrated in FIG. 9, the learning unit 160 learns the user set state pattern by aggregating the average of the standard state patterns of each user in the user set. For example, by aggregating the average of the daily standard transition patterns of each item in the user set, the average daily transition pattern of each item in the user set is learned. Further, for example, the average weekly transition pattern of each item is aggregated in the user set, so that the average weekly transition pattern of each item in the user set is learned.

The learning unit 160 stores data indicating the learning result of the standard state pattern of the attention user and the user set state pattern in the storage unit 162.

It should be noted that the timing of learning the standard state pattern of the attention user and the learning of the user set state pattern do not necessarily have to be synchronized, and may be performed at different timings.

After that, the process proceeds to step S4.

On the other hand, if it is determined in step S2 that the standard state pattern of the attention user is not learned, the process of step S3 is skipped and the process proceeds to step S4.

In step S4, the diagnosis unit 154 performs a driving diagnosis during non-driving. For example, the diagnostic unit 154 has a transition pattern (hereinafter, 1 day and 1 week) within the latest relatively short-term period (for example, 1 day and 1 week) for the same item as the above-mentioned standard state pattern based on the estimated state history of the user of interest. (Referred to as the latest state pattern) is detected.

Next, the diagnostic unit 154, for example, as illustrated in FIG. 10, has a deviation degree vector x indicating the degree of deviation between the latest state pattern of the attention user and the standard state pattern, and the latest state pattern of the attention user and the user. The deviation degree vector y indicating the deviation degree from the set state pattern is calculated. For example, the divergence degree vector x and the divergence degree vector y are vectors including a value obtained by normalizing the divergence degree for each item of the two state patterns to be compared.

Then, the diagnosis unit 154 calculates the driving suitability u of the attention user during non-driving by using the driving diagnosis model of the attention user represented by the function f of the following equation (1).

u = f (x, y, wx, wy) ... (1)

Note that wx is a weight for the deviation degree vector x, and wy is a weight for the deviation degree vector y.

The driving suitability u becomes larger as the degree of deviation of each item included in the degree of deviation vector x becomes smaller. That is, it is determined that the closer the nearest state pattern of the attention user is to the standard state pattern, in other words, the smaller the difference between the latest state and the standard state of the attention user is, the more suitable the state is for driving. .. On the other hand, the driving suitability u becomes smaller as the degree of deviation of each item included in the degree of deviation vector x increases. That is, it is determined that the farther the attention user's latest state pattern is from the standard state pattern, in other words, the larger the difference between the attention user's latest state and the standard state, the more unsuitable for driving. NS.

Further, the driving suitability u becomes larger as the degree of deviation of each item included in the degree of deviation vector y becomes smaller. That is, the closer the latest state pattern of the attention user is to the user set state pattern, in other words, the smaller the difference between the latest state of the attention user and the average state in the user set, the more suitable the state for driving. Is determined. On the other hand, the driving suitability u becomes smaller as the degree of deviation of each item included in the degree of deviation vector y becomes larger. That is, the farther the latest state pattern of the attention user is from the user set state pattern, in other words, the larger the difference between the latest state of the attention user and the average state in the user set, the more unsuitable for driving. It is determined that there is.

The larger the weight wx, the greater the influence of the deviation degree vector x (that is, the difference between the latest state pattern and the standard state pattern of the user of interest) on the driving suitability u. On the other hand, the larger the weight wy, the greater the influence of the deviation degree vector y (that is, the difference between the user set state pattern of the attention user and the standard state pattern) on the driving suitability u.

Further, for example, when the driving suitability u is less than a predetermined threshold value, the diagnosis unit 154 estimates a factor for lowering the driving suitability u. For example, the diagnosis unit 154 extracts an item in the deviation degree vector x in which the product of the weight wx and the deviation degree is equal to or larger than a predetermined value. Further, the diagnosis unit 154 extracts an item in the deviation degree vector y in which the product of the weight wy and the deviation degree is equal to or more than a predetermined value. Then, the diagnostic unit 154 estimates the factors that reduce the driving suitability u by comparing the latest state pattern with the standard state pattern or the user set average pattern for each of the extracted items.

For example, when the sleep time in the latest state pattern of the attention user is significantly lower than the standard state pattern or the user set average pattern, it is presumed that sleep deprivation is a lowering factor.

For example, if one or more of the exercise time, heart rate, and sweating amount in the most recent state pattern of the user of interest is significantly higher than the standard state pattern or the user set average pattern, physical fatigue due to strenuous exercise is a lowering factor. It is estimated to be.

For example, if one or more of the stress, tension, and impatience in the immediate state pattern of the attention user is significantly higher than the standard state pattern or the user set average pattern, the impatience of the attention user is a lowering factor. Presumed to be.

When the driving suitability u is equal to or higher than a predetermined threshold value, for example, there is no particular factor for lowering the driving suitability u.

The diagnosis unit 154 stores the driving aptitude u and the estimated lowering factor in the storage unit 162 as a diagnosis result of the driving aptitude of the user of interest together with the time of diagnosis. As a result, the driving diagnosis history of the attention user is updated.

In step S5, the risk prediction unit 156 makes a risk prediction. Specifically, the risk prediction unit 156 acquires the driving diagnosis history and the risk prediction model of the attention user from the storage unit 162. The risk prediction unit 156 predicts the risk when the attention user drives at the present time by using the risk prediction model of the attention user based on the driving diagnosis history of the attention user.

For example, if the factor that lowers the driving aptitude u is lack of sleep or physical fatigue, it is presumed that there is a risk of drowsy driving.

For example, when the factor for lowering the driving aptitude u is the impatience of the attention user, for example, a collision or contact with another vehicle due to overspeed or unreasonable overtaking, and an obstacle due to carelessness of the attention user (for example, other). It is estimated that there is a risk of collision or contact with vehicles, bicycles, pedestrians, etc.).

In addition, the risk prediction unit 156 estimates the probability of occurrence of the predicted risk. For example, the shorter the sleep time of the attention user, the higher the estimated probability of drowsy driving.

In general, the lower the driving suitability u, the greater the predicted risk and probability of occurrence.

The risk prediction unit 156 supplies the risk prediction result to the damage prediction unit 157. The prediction result of this risk includes the predicted risk, the basis for predicting the risk (for example, the factor for lowering the driving suitability u), and the probability of occurrence of the risk.

In step S6, the damage prediction unit 157 makes a damage prediction. Specifically, the damage prediction unit 157 predicts the damage (for example, risk / penalty value) caused by the risk predicted by the risk prediction unit 156. At this time, the probability of occurrence of risk is taken into consideration. That is, the higher the probability of occurrence, the larger the predicted damage, and the lower the probability of occurrence, the smaller the predicted damage. The damage prediction unit 157 supplies the risk and damage prediction results to the driving behavior detection unit 155 and the presentation control unit 158.

In step S7, the driving behavior detection unit 155 adjusts the driving behavior detection parameters. For example, the driving behavior detection unit 155 adjusts the parameters for detecting dangerous driving among various driving behaviors according to the predicted risk and damage.

Here, the driving behavior related to the detection of dangerous driving includes, for example, sudden start, sudden acceleration, sudden braking, sudden operation such as sudden steering, meandering driving, dozing driving, decrease in alertness and concentration, and inattentive driving. Dangerous driving behavior such as carelessness ahead, overspeeding, unreasonable overtaking, insufficient inter-vehicle distance, and approaching obstacles.

In addition, the detection parameters are adjusted so that the higher the estimated risk and damage, the lower the level (risk level) of dangerous driving to be detected. As a result, dangerous driving can be detected from an earlier and minor stage.

For example, when the occurrence of drowsiness is predicted, the threshold value of the number of blinks in the drowsiness determination is reduced so as to detect the drowsiness of the user earlier. For example, when it is predicted that inattentive driving, carelessness in front, overspeed, etc. will occur, the threshold value for detecting sudden acceleration or sudden braking is reduced so that sudden acceleration or sudden braking can be easily detected.

Further, the lower the level of dangerous driving to be detected, the lower the level (risk level) of risk to be predicted. That is, risk at an earlier and minor stage can be predicted.

Here, the level of dangerous driving to be detected and the level of risk to be predicted change depending on the driving aptitude u of the user of interest. For example, as described above, in general, the lower the driving suitability u, the greater the predicted risk and the probability of damage occurrence, and the larger the predicted damage. Therefore, the detection parameters are adjusted so that the level of dangerous driving to be detected is lower. As a result, the lower the driving aptitude u, the lower the level of dangerous driving to be detected and the level of risk to be predicted.

In step S8, the presentation control unit 158 determines whether or not to give feedback to the user (attention user). Feedback to the attention user is executed at a predetermined timing. For example, when a feedback request is transmitted from the user terminal unit 11 of the attention user, the feedback is executed every time a predetermined time elapses, or when a serious risk is predicted. Then, when the present time is the timing for giving feedback to the attention user, the presentation control unit 158 determines that the feedback to the attention user is given, and the process proceeds to step S9.

In step S9, the server 13 provides feedback to the user (attention user). Specifically, the presentation control unit 158 generates feedback information to be presented to the attention user. This feedback information is, for example, the result of the driving diagnosis of the attention user, the content of the predicted risk, the basis of the driving diagnosis result or the basis for predicting the risk, and the proposal for avoiding the risk (hereinafter referred to as a risk avoidance plan). ) Includes one or more. The presentation control unit 158 transmits the generated feedback information to the user terminal unit 11 of the user of interest via the communication unit 151.

For example, when the mobile terminal 51 of the attention user receives the feedback information, the output unit 66 of the mobile terminal 51 uses at least one of the visual information (for example, video) and the auditory information (for example, voice) for the feedback information. Is presented to the attention user. Further, for example, when the wearable terminal 52 of the attention user receives the feedback information, the output unit 83 of the wearable terminal 52 presents the feedback information to the attention user using at least one of the visual information and the auditory information.

For example, if the attention user is presumed to be sleep deprived, a voice message such as "Sleep deprivation. It is recommended to take a little sleep before driving." Is output.

Further, for example, as the driving diagnosis result of the user of interest, the driving suitability u is presented by the value of a predetermined stage (for example, 10 stages), and the basis thereof is presented.

Further, for example, the estimation result of the state of the attention user may be presented. For example, emotional indexes such as emotions, excitement, and aggression of the attention user may be presented from the values of predetermined stages (for example, 10 stages).

After that, the process proceeds to step S10.

On the other hand, if it is determined in step S8 that feedback to the attention user is not performed, the process of step S9 is skipped and the process proceeds to step S10.

In step S10, the state estimation unit 152 determines whether or not the user (attention user) has started the operation. Specifically, the state estimation unit 152 determines whether or not the attention user has started driving based on the data received from at least one of the user terminal unit 11 and the vehicle 12 of the attention user via the communication unit 151. Is determined.

The operation start determination process may be performed by any of the user terminal unit 11, the vehicle 12, and the server 13. For example, the mobile terminal 51 may execute the driving start determination process by performing the driving recognition process of the user of interest or performing beacon synchronization with the vehicle 12. Further, for example, a measuring device integrated with an in-vehicle display device of the vehicle 12 or the like may execute the operation start determination process.

When the determination process is performed by the user terminal unit 11 or the vehicle 12, the determination result is included in the data transmitted from the user terminal unit 11 or the vehicle 12, and the state estimation unit 152 pays attention based on the determination result. Determine if the user has started driving.

Then, if it is determined that the attention user has not started the operation, the process returns to step S2. After that, in step S10, the processes of steps S2 to S10 are repeatedly executed until it is determined that the user of interest has started the operation. As a result, driving diagnosis, risk prediction, and damage prediction of the attention user are appropriately performed, and based on the results, adjustment of detection parameters for dangerous driving and feedback to the attention user are performed. In addition, the standard state pattern of the attention user and the user set state pattern are updated as appropriate.

On the other hand, if it is determined in step S10 that the user of interest has started the operation, the process proceeds to step S11.

In step S11, the server 13 starts the estimation process of the state of the user (attention user) during operation. This estimation process is significantly different from the estimation process in step S1 in that the estimation process is performed based on the data transmitted from the vehicle 12 in addition to the user terminal unit 11 of the user of interest.

For example, the line of sight, blinking, facial expression, etc. of the attention user are detected based on the video data from the vehicle 12, and are used for estimating the concentration degree, alertness degree, fatigue degree, emotion, etc. of the attention user. Further, for example, the content of the driving operation of the user of interest is estimated based on the vehicle data from the vehicle 12.

Further, for example, the state of the attention user is estimated based on the traveling route of the vehicle 12 and the time zone in which the attention user is driving. For example, after the heart rate and the amount of exercise of the attention user rapidly increase, the attention user drives at an unusual time zone (for example, midnight or early morning), or the vehicle 12 moves out of the range of the attention user's daily life. When driving, it is presumed that the user of interest is impatient due to some emergency.

Further, the state estimation unit 152 appropriately updates the state data log and the estimated state history of the user of interest, as in the process of step S1.

In step S12, the peripheral data acquisition unit 153 starts acquiring peripheral data of the vehicle 12. For example, the peripheral data acquisition unit 153 is based on the position information transmitted from the user terminal unit 11 or the vehicle 12 and the map information received from another server or the like via the communication unit 151, and the vehicle of the attention user. It detects the conditions of the surrounding structures, roads, traffic jams, weather, etc. Further, for example, the peripheral data acquisition unit 153 may use an object around the vehicle 12 (for example, a vehicle, a person, etc.) based on video data, audio data, sensor data, and the like transmitted from the user terminal unit 11 or the vehicle 12. Detects obstacles, structures, roads, traffic lights, traffic signs, road signs, etc.). The user terminal unit 11 or the vehicle 12 may perform detection processing of an object around the vehicle 12 and transmit the detection result to the server 13.

The peripheral data acquisition unit 153 supplies the acquired peripheral data of the vehicle 12 to the diagnosis unit 154 and the risk prediction unit 156.

In step S13, the server 13 starts the operation behavior detection process. Specifically, for example, the following processing is started.

Among the data received by the communication unit 151 from the user terminal unit 11 and the vehicle 12 of the attention user, the driving behavior detection unit 155 transmits data related to the driving behavior (for example, the behavior of the attention user or the vehicle 12 while driving) to the communication unit 151. Get from. Further, the driving behavior detection unit 155 is based on the acquired data on the driving behavior, the estimated state history of the user of interest stored in the storage unit 162, and the peripheral data of the vehicle 12 acquired from the peripheral data acquisition unit 153. The driving behavior is detected by using the driving behavior detection model of the user of interest stored in the storage unit 162. That is, the behavior of the user of interest during driving and the behavior of the vehicle 12 are detected. For example, the speed, acceleration, deceleration, brake operation, steering angle, traveling route, etc. of the vehicle 12 are detected.

A part of the behavior of the user of interest during driving may be detected (estimated) by the state estimation unit 152 in step S11.

Further, the detection of the driving behavior may be performed by any of the user terminal unit 11, the vehicle 12, and the server 13, or may be shared by the user terminal unit 11, the vehicle 12, and the server 13. ..

Next, the driving behavior detection unit 155 performs dangerous driving detection processing based on the detected driving behavior, the estimated state history of the user of interest, and the peripheral data of the vehicle 12.

For example, a sudden operation is detected by a sudden change in speed, steering angle, torque, etc. of the vehicle 12 based on OBD information or the like, or a sudden change in acceleration, angular velocity, etc. detected by the user terminal unit 12.

For example, meandering operation is detected by periodic fluctuations in the speed, steering angle, torque, etc. of the vehicle 12 based on OBD information, etc., or by periodic fluctuations in acceleration, angular velocity, etc. detected by the user terminal unit 12. ..

For example, a shortage of inter-vehicle distance is detected by the position of the preceding vehicle detected by using a stereo camera, a laser radar, or a millimeter-wave radar.

Here, the detection parameters adjusted in step S7 described above or step S20 described later are used for the detection process of dangerous driving. Therefore, as described above, the lower the driving aptitude u of the attention user, the lower the level of dangerous driving to be detected, and the detection target is detected as dangerous driving from an earlier and more minor stage. ..

The driving behavior detection unit 155 stores the driving behavior detection result in the storage unit 162 together with the detected time. As a result, the driving behavior history of the user of interest is updated.

In step S14, the diagnosis unit 154 performs a driving diagnosis during driving. For example, the diagnosis unit 154 determines the driving suitability u by using the driving diagnosis model of the attention user stored in the storage unit 162 based on the estimated state history of the attention user after the start of operation and the driving behavior history. to correct.

For example, when the concentration or alertness of the attention user is lowered or the fatigue, stress, or tension of the attention user is increased, the driving aptitude u is lowered. On the other hand, for example, when the concentration or alertness of the attention user is increased, or the fatigue, stress, or tension of the attention user is decreased, the driving suitability u is increased. Further, for example, when dangerous driving is detected, the driving suitability u is lowered according to the detection frequency. On the other hand, when the state in which dangerous driving is not detected continues, the driving suitability u is increased according to the duration.

The driving suitability u is corrected based on the good or bad of the driving operation of the attention user such as the smoothness of the brake and accelerator pedal depression, the steering wheel handling when cornering, and the smoothness of acceleration and deceleration. You may.

The diagnosis unit 154 stores the corrected driving suitability u and the estimated lowering factor in the storage unit 162 as a diagnosis result of the driving suitability of the user of interest together with the time of diagnosis. As a result, the driving diagnosis history of the attention user is updated.

In step S15, the risk prediction unit 156 makes a risk prediction. Here, unlike the process of step S5, the risk prediction unit 156 further uses the estimated state history and the driving behavior history of the attention user stored in the storage unit 162 in addition to the operation diagnosis history of the attention user to perform the risk. Make a prediction. For example, even if the driving suitability u of the attention user is high, the higher the detection frequency of dangerous driving and the higher the risk of detected dangerous driving, the greater the predicted risk. On the other hand, for example, even if the driving suitability u of the attention user is low, if dangerous driving is not detected, the predicted risk becomes small. As described above, since the risk prediction is performed by further using the driving state and the driving behavior of the actual attention user, the accuracy of the risk prediction is improved as compared with the process of step S5.

Further, the risk prediction unit 156 can predict not only the risk and its occurrence probability but also the time when the risk occurrence probability becomes high in the future (hereinafter referred to as the risk increase time). For example, the risk prediction unit 156 estimates the time when they fall below a predetermined threshold value as the risk increase time based on the time-series changes in the concentration, tension, or alertness of the attention user.

The risk prediction unit 156 supplies the risk prediction result to the damage prediction unit 157. The risk prediction result includes the content of the predicted risk, the basis for predicting the risk (for example, the factor for lowering the driving suitability u and the detection result of dangerous driving), and the probability of occurrence of the risk. Also, if necessary, the risk increase time is included.

In step S16, damage prediction is performed in the same manner as in the process of step S6. However, unlike the process of step S6, the damage prediction unit 157 further uses the obedience degree of the attention user to predict the damage. That is, the higher the degree of obedience of the attention user, the higher the possibility of avoiding the risk, and the lower the degree of obedience, the lower the possibility of avoiding the risk. Therefore, the higher the degree of obedience, the smaller the expected damage, and the lower the degree of obedience, the greater the expected damage. The damage prediction unit 157 supplies the risk and damage prediction results to the driving behavior detection unit 155 and the presentation control unit 158.

Here, the level of dangerous driving to be detected and the level of risk to be predicted change depending on the degree of obedience of the user of interest. For example, as mentioned above, the lower the obedience of the attention user, the greater the risk loss expected. Therefore, the detection parameters are adjusted so that the level of dangerous driving to be detected is lower. As a result, the lower the degree of obedience, the lower the level of dangerous driving to be detected and the level of risk to be predicted.

In step S17, the presentation control unit 158 determines whether or not to give feedback to the user (attention user). For example, if the presentation control unit 158 predicts that a risk that needs to be notified to the attention user will occur, it determines that feedback to the attention user will be given, and the process proceeds to step S18.

In step S18, feedback to the attention user is performed as in the process of step S8. Here, a specific example of the feedback information presented to the attention user will be described.

For example, when sleep deprivation of the attention user is estimated and sudden operation or meandering driving is detected, attention is given to dangerous driving. For example, in the user terminal unit 11 or the vehicle 12 of the attention user, a voice message such as "Insufficient sleep. Please drive carefully." Is output. For example, the part "Please drive carefully" is the risk aversion plan, and the part "I am in a state of lack of sleep" is the basis for presenting the risk aversion plan.

For example, when it is presumed that the user of interest is out of the service area of daily life, or when it is presumed that the user is feeling strong stress and an approach to a vehicle in front is detected, a warning for dangerous driving is issued. Will be. For example, a voice message such as "Are you in a hurry? Let's drive calmly." Is output from the user terminal unit 11 or the vehicle 12 of the attention user. For example, the part "Let's drive calmly" is the risk aversion plan, and the part "Are you in a hurry?" Is the basis for presenting the risk aversion plan.

For example, it is dangerous when it is presumed that the attention user was exercising violently before driving, when one point concentration of the attention user's line of sight is detected, or when a large number of pedestrians are detected around the vehicle 12. Attention is given to the risk of driving. For example, a voice message such as "Are you sleepy? Please drive while paying attention to the surroundings." Is output from the user terminal 11 or the vehicle 12 of the attention user. For example, the part "Please drive carefully around you" is the risk aversion plan, and the part "Are you sleepy?" Is the basis for presenting the risk aversion plan.

For example, when it is estimated that the attention user is out of the service area of daily life, or when the attention user is estimated to be sleep deprived, and sudden operation or meandering driving is detected while driving on the highway, it is dangerous. A warning for driving is given. For example, a voice message such as "Why don't you take a break in the next service area? You were short of sleep yesterday and are currently meandering" is output on the user terminal 11 or vehicle 12 of the attention user. NS. For example, the part "Why don't you take a break in the next service area?" Is the risk aversion plan, and the part "You were short of sleep yesterday and are currently meandering" is the basis for presenting the risk aversion plan. Will be.

For example, when sleep deprivation or extreme tension of a noted user is presumed and dangerous driving is frequently detected, attention is given to an increase in automobile insurance premiums and the cause thereof is presented. For example, in the user terminal 11 or the vehicle 12 of the attention user, "dangerous driving due to lack of sleep (or tension) frequently occurs. When x more dangerous driving is detected, the right to cash back insurance premiums is granted. A voice message such as "I will lose." Is output. For example, the part "If x more dangerous driving is detected, the right to cash back insurance premiums will be lost" will be a warning to the attention user, and "Dangerous driving due to lack of sleep (or tension) is occurring frequently. The "masu" part is the basis for issuing a warning.

For example, if it is estimated that the user of interest is driving on an unfamiliar road outside the service area of daily life, and the risk increase time due to fatigue is estimated, "Are you tired? Why not take a break in service area A?" A voice message such as "Is it?" Is output. The service area A is a service area in which the vehicle 12 of the attention user is estimated to be reachable by the time when the risk increases. For example, the part "Why don't you take a break in service area A?" Is the risk aversion plan, and the part "Are you tired?" Is the basis for presenting the risk aversion plan.

The risk aversion plan can be made more specific, for example, "Please slow down to 60 km / h" or "Please turn to the front immediately."

Further, the presentation control unit 158 supplies feedback information to the evaluation unit 159.

In step S19, the evaluation unit 159 evaluates the obedience degree of the user (attention user). Specifically, the evaluation unit 159 acquires the estimated state history and the driving behavior history of the attention user after the feedback to the attention user is given from the storage unit 162. Then, the evaluation unit 159 detects the reaction of the user of interest to the feedback (for example, the content of driving) based on the acquired history.

Further, the evaluation unit 159 updates the evaluation value of the obedience degree of the attention user based on the reaction of the attention user. For example, if the feedback information presented this time includes a risk avoidance plan and the attention user follows the risk avoidance plan, the degree of obedience of the attention user increases. In addition, the shorter the time it takes for the attention user to follow the risk avoidance plan (the faster the reaction speed), or the smaller the difference between the attention user's reaction and the risk avoidance plan, the greater the increase in the degree of obedience of the attention user. .. Conversely, the longer it takes for the attention user to follow the risk aversion plan (the slower the reaction speed), or the larger the difference between the attention user's reaction and the risk aversion plan, the smaller the increase in obedience of the attention user. Become.

On the other hand, if the attention user does not follow the risk aversion plan, for example, if the attention user ignores the risk aversion plan, or if the attention user reacts differently from the risk aversion plan, the obedience degree of the attention user is descend. In particular, when the attention user performs dangerous driving without following the risk aversion plan, the degree of obedience of the attention user is greatly reduced.

The evaluation unit 159 supplies the updated obedience degree of the attention user to the damage prediction unit 157 and stores it in the storage unit 162.

After that, the process proceeds to step S20.

On the other hand, if it is determined in step S17 that feedback to the attention user is not performed, the processing of steps S18 and S19 is skipped, and the processing proceeds to step S20.

In step S20, the detection parameters of the driving behavior are adjusted in the same manner as in the process of step S7.

In step S21, the state estimation unit 152 determines whether or not the user has stopped the operation. That is, the state estimation unit 152 pays attention based on the data received from at least one of the user terminal unit 11 and the vehicle 12 of the user of interest via the communication unit 151, as in the operation start determination process of step S10. Determine if the user has stopped operation.

Then, if it is determined that the attention user has not stopped the operation, the process returns to step S14. After that, in step S21, the processes of steps S14 to S21 are repeatedly executed until it is determined that the user of interest has stopped the operation. As a result, driving diagnosis, risk prediction, and damage prediction of the attention user are appropriately performed, and based on the results, adjustment of detection parameters for dangerous driving and feedback to the attention user are performed. In addition, the obedience of the attention user is updated as appropriate.

On the other hand, if it is determined in step S21 that the user of interest has stopped the operation, the process proceeds to step S22.

In step S22, as in the process of step S1, the process of estimating the state of the user of interest during non-driving is started.

In step S23, the peripheral data acquisition unit 153 stops acquiring data around the vehicle 12.

In step S24, the driving behavior detection unit 155 stops the driving behavior detection process.

In step S25, the learning unit 160 performs the learning process. For example, the learning unit 160 has a state estimation model, a driving diagnosis model, and a driving behavior detection based on the state data log, the estimated state history, the driving diagnosis history, and the driving behavior history of the user of interest stored in the storage unit 162. Learn the model and risk prediction model.

For example, when safe driving is performed even though the driving suitability u is evaluated low, the weight wx and the weight wy of the equation (1) representing the above-mentioned driving diagnosis model are set small. As a result, the driving aptitude u of the attention user will be evaluated higher than before. On the contrary, when the dangerous driving is frequently performed even though the driving suitability u is highly evaluated, the weight wx and the weight wy of the equation (1) are set large. As a result, the driving aptitude u of the attention user will be evaluated lower than before.

Further, for example, when safe driving is performed even though the difference between the latest state pattern of the attention user and the user set state pattern is large and the driving suitability u is evaluated low, the above-mentioned equation (1) The weight wx is increased and the weight wy is decreased. That is, in the operation diagnosis, the difference between the latest state pattern and the standard state pattern of the user of interest becomes more important.

For example, at the beginning of the use of the service by the attention user, a model corresponding to the average user obtained by a preliminary experiment or the like is used. After that, each model is updated (personalized) to a model more suitable for the user of interest by the learning process.

It should be noted that this learning process does not necessarily have to be performed every time the operation of the attention user is completed, for example, every predetermined period, every time the operation is performed a predetermined number of times, every time the operation time increases by a predetermined time or more, and the like. It may be performed at any timing. Further, it is not always necessary to perform the learning process of all the models at the same time, and the learning process may be performed at different timings for each model.

Further, for example, the learning unit 160 may learn a fatigue degree estimation model that predicts the fatigue degree of the attention user based on the transition of the fatigue degree of the attention user before and during the operation shown in the estimated state history. good. For example, the state estimation unit 152 can estimate the fatigue level of the user of interest at each point of the planned travel route by using the fatigue level estimation model. Further, for example, the learning unit 160 learns the fatigue degree estimation model by taking into consideration the conditions around the vehicle 12 such as the time zone, the weather, the traffic condition, and the type of road (for example, a general road or a highway). By doing so, the estimation accuracy of the degree of fatigue can be improved.

Further, as the learning processing method, for example, machine learning such as a neural network or any other method can be used.

In step S26, the insurance premium calculation unit 161 calculates the insurance premium of the user (attention user). For example, when the insurance premium of the attention user or the cashback amount for the insurance premium fluctuates in real time, the insurance premium calculation unit 161 may store the attention user's driving diagnosis history, driving behavior history, etc. in the storage unit 162. And, the insurance premium or cashback amount is updated based on the degree of obedience. The insurance premium calculation unit 161 stores the updated insurance premium or cashback amount of the attention user in the storage unit 162.

For example, the lower the average value of driving aptitude u, the higher the insurance premium (or the lower cashback amount), and the higher the average value of driving aptitude u, the lower the insurance premium (or the cashback amount). Will go up).

Also, for example, the higher the frequency or cumulative number of dangerous driving, the higher the insurance premium (or the lower cashback amount), and the smaller the frequency or cumulative number of dangerous driving, the lower the insurance premium (or the cashback amount). Will go up). Further, for example, the higher the average or total expected damage to dangerous driving, the higher the insurance premium (or the lower the cashback amount), and the lower the average or total expected damage to dangerous driving. The lower the insurance premium (or the higher the cashback amount).

Also, for example, the lower the obedience level, the lower the risk cannot be expected, so the insurance premium increases (or the cashback amount decreases), and the higher the obedience level, the lower the risk can be expected, so the insurance premium decreases. (Or, the cashback amount will increase). In particular, when a user of interest performs dangerous driving without following the risk aversion plan, for example, as a penalty, the amount of increase in insurance premiums (or the amount of decrease in cashback amount) becomes large.

It should be noted that this insurance premium calculation process does not necessarily have to be performed every time the driving of the attention user is completed, for example, every predetermined period, every predetermined number of times of driving, and every time the driving time increases by a predetermined time or more. It may be performed at any timing such as.

Further, this insurance premium calculation process may be executed, for example, to calculate the estimated amount of insurance premium at the time of the next insurance renewal.

Further, for example, in the case of automobile insurance for each driving or for one day, the insurance premium may be calculated by executing this insurance premium calculation process before driving. In this case, the insurance premium is calculated using, for example, at least one of the driving aptitude u and the obedience of the user of interest.

In addition, the calculated insurance premium or cashback amount may be presented to the attention user as feedback information.

After that, the process returns to step S2, and the processes after step S2 are executed.

For example, driving behavior is influenced not only by the state of the user during driving but also by the state of the user before driving (for example, behavior, biological state, emotion, etc.). On the other hand, as described above, the driving suitability u is evaluated more appropriately by considering the user's state before driving in addition to the driving state and driving behavior of the user. Further, by improving the accuracy of the driving suitability u, the accuracy of risk prediction and damage prediction is improved. As a result, it is possible to present appropriate feedback information at a more appropriate timing, improve safety, and prevent the occurrence of an accident.

In addition, since the feedback information shows the basis of the result of the driving diagnosis or the basis of predicting the risk, the user's sense of conviction is improved and the probability that the user follows the risk avoidance plan is increased. Further, when the presented grounds are incorrect, for example, the user instructs the server 13 to make corrections and reflects them in the learning process, so that the accuracy of the driving diagnosis model and the risk prediction model is improved.

Furthermore, the user's obedience is evaluated, and the level of dangerous driving to be detected and the level of risk to be predicted change based on the obedience, so that the user can avoid the risk more surely. Will be able to.

In addition, by calculating the insurance premium (including cashback amount) of automobile insurance based not only on the driving behavior of the user but also on the driving aptitude u and obedience, a more appropriate insurance premium can be set for each user. Can be done. As a result, for example, the user can be motivated to follow the risk aversion plan, and the user can more surely avoid the risk.

<< 2. Modification example >>
Hereinafter, a modified example of the embodiment of the technique according to the present disclosure described above will be described.

<Modification example of system configuration>
The configuration example of the information processing system 10 of FIGS. 1 to 4 is an example thereof, and can be changed as needed.

For example, in the above description, an example is shown in which the server 13 performs most of the processing based on the data acquired from the user terminal unit 11 and the vehicle 12 (vehicle-mounted system 101). For example, the user terminal unit 11 and the vehicle It is also possible that the processing is shared by the 12 and the server 13, or the processing is performed independently by the user terminal unit 11 or the vehicle 12.

For example, at least one of the user terminal unit 11 and the vehicle 12 can perform a part or all of the processing of the server 13.

For example, at least one of the user terminal unit 11 and the vehicle 12 performs a part or all of the processing of the state estimation unit 152, the driving behavior detection unit 155, and the evaluation unit 159, and transmits the estimation result and the detection result to the server 13. You may try to do it.

For example, at least one of the user terminal unit 11 and the vehicle 12 may perform a part or all of the processing of the peripheral data acquisition unit 153 and transmit the acquired peripheral data to the server 13.

For example, at least one of the user terminal unit 11 and the vehicle 12 performs a part or all of the processing of the diagnosis unit 154, the risk prediction unit 156, and the damage prediction unit 157, and transmits the diagnosis result and the prediction result to the server 13. You may do so.

Further, for example, the user terminal unit 11 may perform processing related to driving support. In this case, the user terminal unit 11 may be configured by a plurality of devices or may be configured by one device. Further, the user terminal unit 11 may acquire various data (for example, vehicle data, video data, audio data, etc.) from the vehicle 12 and use them for processing, or may use the data from the vehicle 12 for processing. You may not. Further, the user set state pattern may or may not be used for the operation diagnosis process. When the user set state pattern is used, for example, the server 13 learns the user set state pattern based on the standard state pattern of each user acquired from the user terminal unit 11 of each user. Then, the server 13 transmits data indicating the user set state pattern to the user terminal unit 11 of each user.

In this case, the insurance premium calculation process may be performed by either the user terminal unit 11 or the server 13. When the user terminal unit 11 performs, for example, an application program for calculating an insurance premium is provided from the server 13. On the other hand, when the server 13 performs, for example, the data necessary for calculating the insurance premium is provided from the user terminal unit 11 to the server 13.

Further, for example, among the processes related to driving support, almost all the processes other than the process of estimating the user's state during non-driving and the process of learning the standard state pattern may be performed by the vehicle 12 (vehicle-mounted system 101). In this case, for example, the user terminal unit 11 performs estimation processing of the user's state during non-driving and learning processing of the standard state pattern, and the data showing the estimated state history and the standard state pattern obtained as a result are collected before driving the vehicle. Send to 12. Then, the vehicle 12 executes the remaining processing. In this case, the user set state pattern may or may not be used for the operation diagnosis process. When the user set state pattern is used, when the user set state pattern is used, for example, the server 13 learns the user set state pattern based on the standard state pattern of each user acquired from the user terminal unit 11 of each user. .. Then, the server 13 transmits data indicating the user set state pattern to the user terminal unit 11 or the vehicle 12 of each user.

In this case, the insurance premium calculation process may be performed by any of the user terminal unit 11, the vehicle 12, and the server 13. When the user terminal unit 11 or the vehicle 12 performs, for example, an application program for calculating an insurance premium is provided from the server 13. On the other hand, when the server 13 performs, for example, the data necessary for calculating the insurance premium is provided to the server 13 from the user terminal unit 11 and the vehicle 12.

Further, for example, the user terminal unit 11 and the server 13 may share the processing. In this case, the data from the vehicle 12 may or may not be used for processing.

Further, for example, the vehicle 12 and the server 13 may share the processing. In this case, for example, the user terminal unit 11 provides the vehicle 12 and the server 13 with data necessary for processing (for example, a user's standard state pattern and the latest state pattern).

Further, for example, the processing may be shared among a plurality of servers. For example, processing related to driving support and processing related to insurance premium calculation may be performed on different servers.

Further, for example, communication between the vehicle 12 and the server 13 may be performed via the user terminal unit 11. In this case, for example, the data from the vehicle 12 is once transmitted to the user terminal unit 11, and then transferred from the user terminal unit 11 to the server 13. Further, the data from the server 13 is once transmitted to the user terminal unit 11, and then transferred from the user terminal unit 11 to the vehicle 12.

Further, for example, communication between the user terminal unit 11 and the server 13 may be performed via the vehicle 12. In this case, for example, the data from the user terminal unit 11 is once transmitted to the vehicle 12, and then transferred from the vehicle 12 to the server 13. Further, the data from the server 13 is once transmitted to the vehicle 12, and then transferred from the vehicle 12 to the user terminal unit 11.

Further, for example, instead of the estimated state history, the state data log before estimating the user's state is directly used to perform the operation diagnosis of the diagnosis unit 154, the risk prediction of the risk prediction unit 156, and the operation behavior detection unit 155. Driving behavior may be detected. In this case, the state estimation unit 152 can be deleted.

<Other variants>
For example, the driving suitability u may be calculated using the current state of the user in addition to the degree of deviation between the user's latest state pattern and the standard state pattern or the user set average pattern. For example, even if the difference between the user's latest state pattern and the standard state pattern is small, for example, if the user's alertness is low, excited, or depressed, dangerous driving is likely to occur. Therefore, for example, among the items indicating the user's state, for the items having a large influence on driving, the current state (for example, alertness, excitement, depression) of those items is set to the driving aptitude degree u. It may be used for calculation.

Further, the estimated user state is not limited to the above-mentioned three types of biological state, behavior, and emotion. For example, only one or two of the above three types may be estimated, or other types of states may be estimated.

Further, for example, the user's behavior, which is normally not expected to directly affect driving, may be used for calculating the driving suitability u. For example, if a user makes an unusual trend of shopping based on the user's purchase history (for example, if they make a very expensive purchase), it is assumed that the user's state (for example, emotion) is different from the usual one. Will be done. Therefore, for example, the user's purchase history may be used to calculate the driving suitability u.

Further, for example, the ability of the user detected based on the state of the user during non-driving, which also affects driving, may be used for calculating the driving suitability u. For example, the driving aptitude u of a user having a high judgment ability in daily life may be set high, and the driving aptitude u of a user having a low judgment ability may be set low.

In this case, for example, even if a user with high judgment ability and a user with low judgment ability repeatedly change lanes frequently, the risk predicted for the user with high judgment ability is low and the judgment ability is low. The expected risk to the user is high. However, even if the user has high judgment ability, if the risk aversion plan is presented to reduce the lane change, but the risk aversion is ignored and the lane change is repeated, the obedience is evaluated low, so it is predicted. The risk is high.

Further, for example, the risk prediction may be performed based on only one or two of the estimation result of the user's condition, the result of the driving diagnosis, and the detection result of the driving behavior. Further, for example, when risk prediction is performed using the result of driving diagnosis, only one of driving aptitude u before driving and driving aptitude u during driving may be used.

Further, for example, the driving diagnosis may be performed based only on the state of one of the users before and during the driving.

Further, for example, it is possible to use the estimated state history, the driving diagnosis history, and the driving behavior history for investigating the cause of the accident. For example, by recording the estimated state history, the driving diagnosis history, and the driving behavior history in the drive recorder, it is based on the state and behavior of the user (driver) at the time of the accident and the state of the user before driving. Therefore, it becomes possible to investigate the cause of the accident.

Further, for example, the user terminal unit 11 or the vehicle 12 can acquire the driving suitability u of another user, the risk prediction result, etc. from the user terminal unit 11 or the vehicle 12 of another user, or the server 13. You may. Thereby, for example, when a dangerous vehicle driven by a user having a low driving suitability u exists nearby, for example, the user can avoid being involved in an accident caused by the dangerous vehicle by acquiring the information in advance. be able to.

Further, the state estimation model, the driving diagnosis model, the driving behavior detection model, and the risk prediction model do not necessarily have to be personalized, and a model using a predetermined algorithm or the like may be used. Further, for example, instead of learning the above model for each user, for example, the learning may be performed for the entire user set, and a common model may be used for each user.

Further, for example, the method of presenting the feedback information, the frequency of presentation, the content of the presentation, and the like may be changed based on the degree of obedience of the user.

<Application example>
The driving support processing of this technology is not limited to the vehicles exemplified above (for example, this technology is used for various moving objects such as motorcycles, bicycles, personal mobility, airplanes, ships, construction machines, agricultural machines (tractors), etc. That is, it is possible to perform driving diagnosis, risk prediction, damage prediction, feedback to the user, etc. by using the estimation result of the state of the user before and during driving. In addition to moving objects to which this technology can be applied, some construction machines (for example, fixed cranes, etc.) that work in a fixed location, etc. The moving body to which the present technology is applied includes, for example, a moving body such as a drone or a robot that is remotely operated (operated) without being boarded by a user.

In addition to automobile insurance, this technology can be applied to systems and devices that provide various types of insurance such as life insurance, non-life insurance, and medical insurance. For example, various insurance premiums (including cashback amount) can be calculated based on the user's estimated state history and obedience. Specifically, for example, in the case of life insurance or medical insurance, the user terminal unit 11 or the server 13 performs a user state estimation process and accumulates an estimated state history. Further, the user terminal unit 11 or the server 13 presents a proposal (risk avoidance plan) for avoiding a risk such as a disease to the user based on the user's lifestyle and biological condition based on the estimated state history, and the reaction thereof. Evaluate the obedience of the user based on. Then, the user terminal unit 11 or the server 13 calculates the insurance premium for life insurance or medical insurance based on the lifestyle and biological condition of the user, the degree of obedience, and the like.

For example, a user with a good lifestyle and a living condition has a lower insurance premium, and a user with a poor lifestyle and a living condition has a higher insurance premium. In addition, the higher the degree of obedience, the lower the insurance premium, and the lower the degree of obedience, the higher the insurance premium. As described above, by considering not only the lifestyle and biological condition of the user but also the obedience of the user, it is possible to set a more appropriate insurance premium for each user as in the case of the above-mentioned automobile insurance.
