Description

The present disclosure relates to an occupant detection system.

Patent Document 1 describes a sleep suggestion device. The sleep suggestion device acquires sleep history information of occupants in other vehicles at points on the planned route that the own vehicle is about to travel, and also determines whether the environment at the point on the planned route is suitable for sleep based on the sleep history information. The degree of sleep suitability indicating whether or not there is a person on the planned route is calculated for each point on the planned route. Then, the sleep suggestion device estimates a bedtime at which the occupant of the own vehicle can go to bed while the own vehicle travels on the scheduled route based on the sleep suitability, and proposes the estimated bedtime to the occupant.

For example, in automatic driving mode, the sleep suggestion device reclines the passenger's (driver's) seat at the start of bedtime (promoting sleep) and returns the seat to its original position at the end of bedtime. Awakens the crew (awakening support).

Patent Document 2 also describes a sound input/output device for a vehicle. The sound input/output device for a vehicle has a sound collection unit that collects the voices of occupants, an output unit that outputs sound or video to each seat, and an alertness detection unit that detects the alertness of the occupant. When the vehicle sound input/output device determines that content related to the vehicle or its surroundings has been spoken based on the voice collected by the sound collection unit, it outputs information related to the vehicle or its surroundings from the output unit only to occupants whose alertness detected by the alertness detection unit is higher than a predetermined value. This ensures the comfort of other sleeping occupants (without disturbing their sleep).

Further, Patent Document 3 describes a vehicle occupant awakening device. The vehicle occupant wake-up device includes a guide route search device that searches for a guide route from the current location to the destination, a biometric information detection device that detects biometric information of the occupant, and determines the sleeping state of the occupant based on the biometric information. The vehicle includes sleep state determining means and wake-up timing setting means for setting the wake-up timing for waking up the occupant. The vehicle is also equipped with an awakening device that wakes up a sleeping occupant. The wake-up device operating means controls the operation of the wake-up device based on the current position of the vehicle on the guide route, the sleep state of the occupant, and the wake-up timing. Thereby, the occupant can be woken up comfortably and reliably before reaching the destination or at the alarm time set by the occupant.

(First embodiment)
The occupant detection system 100 of the first embodiment will be explained using FIGS. 1 to 7. The occupant detection system 100 detects a plurality of occupants 20 riding on the vehicle 10 and provides support for sleep and wakefulness of the occupants 20. In addition, when a state change occurs in the passenger 20 during driving, the passenger detection system 100 selects the passenger 20 (person suitable for handling the situation) from among the plurality of passengers 20 who should take action regarding the state change. The system selects the occupant 20 and instructs the occupant 20 to be treated.

The vehicle 10 is, for example, a five-seater passenger car, and includes a driver's seat 11, a passenger's seat 12, a left rear seat 13, a right rear seat 14, and the like. The occupant detection system 100 of the present disclosure is used under the condition that the plurality of occupants 20 include a driver 21 and two or more fellow passengers. Here, as shown in FIG. 1, the occupants 20 are a driver 21, a front passenger 22, a rear left passenger 23, and a rear right passenger 24, as an example. As for the configuration (attributes) of the occupants 20, it is assumed that, for example, the driver 21, the front passenger seat 22, and the left rear seat occupant 23 are adults, and the right rear seat occupant 24 is a child.

Changes in the condition of the occupant 20 during driving are mainly assumed to result in trouble occurring. The troubles include, for example, car sickness, sudden abdominal pain, crying of a child (infant), or spilled drink. Hereinafter, the change in the state of the occupant 20 will be referred to as "trouble".

Here, the vehicle 10 is equipped with an automatic driving device and a car navigation device.

The automatic driving device is capable of implementing automatic driving levels 1 to 5 based on the driving state of the vehicle 10, the driving environment (the road on which the vehicle is traveling, the surrounding environment), and the like. In FIGS. 2 to 6, the automatic driving level is expressed as "AD Lv". Automated driving level 1 is a driving level in which the automated driving device supports either steering operation or acceleration/deceleration operation. Automatic driving level 2 is a driving level in which the automatic driving device supports both steering operation and acceleration/deceleration operation. Automatic driving level 3 is a driving level in which the automatic driving device performs all operations at a specific location, but in an emergency, the driver 21 operates. The automatic driving level 4 is a driving level in which the automatic driving device performs all operations in place of the driving by the driver 21 at a specific location. Note that after passing a specific location, the driver 21 is required to drive. The automatic driving level 5 is a driving level in which the automatic driving device performs all operations in place of the driving by the driver 21, regardless of location. At automatic driving levels 3 to 5, while the automatic driving device is performing driving operations, the driver 21 can perform second tasks (activities other than driving, such as sleeping, reading, and watching movies).

Furthermore, the car navigation device uses a GPS (Global Positioning System) to determine the position of the vehicle, displays the result on a map screen, and provides destination guidance to a desired destination.

As shown in FIGS. 1 and 2, the occupant detection system 100 includes a detection section 110, an acquisition section 120, an input section 130, an awakening section 140, an instruction section 150, an instruction control section 160, and the like.

The detection unit 110 is a part that detects attributes, states, etc. of the plurality of occupants 20. The attributes of the occupant 20 are items indicating, for example, whether the occupant is an adult or a child, male or female, and the like. The difference between adults and children is mainly detected from the difference in physique. Also, the state of the occupant 20 is, for example, awake or asleep, relaxed, concentrating on something (games, smartphone, movie on the in-car display, etc.), or normal. This item indicates whether an abnormality (trouble) has occurred. The detection unit 110 includes, for example, a driver monitor 111, an occupant monitor 112, a biological sensor 113, and the like.

The driver monitor 111 is a camera that is provided, for example, on a steering column or a meter hood, and that acquires (takes pictures) an image of mainly the upper body (including the face) of the driver 21. As the driver monitor 111, for example, a CCD camera, a CMOS camera, an infrared camera, or the like is used. The driver monitor 111 outputs the acquired upper body image data of the driver 21 to the instruction control unit 160.

The occupant monitor 112 is, for example, a camera that is provided in the center of the front of the ceiling of the vehicle 10 and that acquires (takes pictures of) images of mainly the upper body (including the face) of each occupant 20. As with the driver monitor 111, the occupant monitor 112 uses, for example, a CCD camera, a CMOS camera, an infrared camera, or the like. The occupant monitor 112 outputs the acquired upper body image data of each occupant 20 to the instruction control unit 160. Note that the driver monitor 111 described above may be replaced by the passenger monitor 112. The passenger monitor 112 (various cameras) can detect the classification of adults and children, as well as the identification of women, men, and individuals through individual recognition.

The biosensor 113 is, for example, a sensor that is provided inside the backrest of each seat 11 to 14 and measures the heart rate, body temperature, posture, etc. of each occupant 20. The biosensor 113 outputs measured data such as heart rate, body temperature, posture, etc. to the instruction control unit 160. The biosensor 113 mainly detects the depth of sleep of the occupant 20, but the occupant monitor 112 described above may be used instead. Furthermore, the biosensor 113 may be a smart watch or the like that is worn on a part of the body of the occupant 20 (such as an arm).

The acquisition unit 120 is a part that acquires information regarding the driving scene (driving situation) of the vehicle 10. The acquisition unit 120 includes a first information acquisition unit 121, a second information acquisition unit 122, and the like.

The first information acquisition unit 121 is connected to the automatic driving device, acquires information on driving scenes associated with automatic driving from the automatic driving device, and outputs various acquired data to the instruction control unit 160. The information on driving scenes associated with automatic driving is information indicating the automatic driving level, whether a second task can be performed, the driving situation (normal driving, high-speed driving, traffic jam driving), and the like.

The second information acquisition unit 122 is connected to the car navigation device, acquires information on driving scenes accompanying navigation driving from the car navigation device, and outputs various acquired data to the instruction control unit 160. Information on driving scenes accompanying navigation driving includes positional information such as driving roads (general roads, expressways), service areas (SA), parking areas (PA), and destinations.

The input unit 130 is a part for inputting which of the other occupants 20 should take care of the problem when the other occupants 20 detect that one of the occupants 20 is in trouble. The input section 130 includes a first input section 131, a second input section 132, and the like. The first input section 131 and the second input section 132 are set at positions where each occupant 20 can perform input operations.

The first input unit 131 is a part for inputting that, when another occupant 20 detects a trouble caused by one of the occupants 20, the other occupant 20 will take care of the problem themselves. In other words, the first input section 131 is a section where the treating person declares that "I will treat this trouble." The treatment signal input at the first input section 131 is output to the instruction control section 160.

When another crew member 20 detects trouble in one of the crew members 20, the second input unit 132 sets a crew member 20 who can treat the trouble among the remaining crew members 20, and inputs an input for requesting treatment. This is the part where this is done. In other words, the second input unit 132 is a part for making a request such as "Mr. A would like Mr. B to take measures regarding this trouble." The request signal input at the second input section 132 is output to the instruction control section 160.

The awakening unit 140 is a part that is set for each occupant 20 and forcibly awakens each occupant 20 when the occupant is sleeping or drowsy. The awakening unit 140 can be, for example, a reclining mechanism for the backrest of each seat 11 to 14, a seat belt having a vibrating unit, a seat air conditioning (cooling) device, a seat massage device, or the like. The operation of the awakening section 140 is controlled by the instruction control section 160.

The instruction unit 150 is a part that instructs only the occupant 20 selected for treatment to take action when a trouble occurs with any of the occupants 20. The instruction unit 150 can be, for example, a directional speaker for audio instructions provided near the ear of each occupant 20, or a display for display instructions set at a position where each occupant 20 can easily see.

The instruction control unit 160 includes a CPU, a RAM, a storage medium, and the like. The instruction control unit 160 determines whether trouble has occurred in any one of the plurality of occupants 20 according to detection data from the detection unit 110, acquisition data from the acquisition unit 120, and various signals from the input unit 130. Detect. Then, the instruction control unit 160 selects the occupant 20 to be treated for the trouble based on the attributes and states of other occupants 20, and when the occupant 20 to be treated needs to be awakened, the instruction control unit 160 140, and the instruction section 150 provides instructions regarding the treatment. Hereinafter, the occupant 20 to be treated will be referred to as a "suitable person".

As shown in FIGS. 3 to 6, the storage medium of the instruction control unit 160 stores in advance a selection map for selecting a suitable person (trouble handler) to deal with troubles of any of the crew members 20. ing. In the embodiments shown in FIGS. 3 to 6, the selection map is based on predetermined priorities based on the attributes (configuration) of the occupants 20, the driving scene, and the status of each occupant 20. This map is used to determine the appropriate person to respond in the event of a crisis.

As described above, the attributes of the occupants 20 are exemplified by the driver 21, the front passenger 22, the rear left passenger 23, and the rear right passenger 24. The driver 21, the passenger 22, and the left rear seat person 23 are adults, and the right rear seat person 24 is a child. In addition, the driving scenes include when riding, driving on a general road, automatic driving level 0 to 2 on an expressway (normal driving, driving in traffic jams), automatic driving level 3 on an expressway (during second task, before driving change), service The example is a case where an abnormality occurs in the area/parking area driving (branching driving or stopping) or in the driver. Furthermore, the states of each occupant 20 are listed as normal, dozing off, and physical condition change. A priority order (displayed by an inequality sign) is set for selecting a suitable person to deal with troubles of the occupant 20.

For example, the idea of setting priorities is as follows:
1. Adults first,
2. Drivers who are permitted to perform second tasks in automated driving (automatic driving level 4 or higher),
3. The person with the least sleepiness among the 20 crew members,
etc. However, when the automatic driving level is 2 and the automatic driving level is 3, the driver may be selected depending on the situation. In areas where the situation is stable and autonomous driving can continue, including highways where sudden changes in driving are unlikely to occur, priority can be given to those who are qualified to handle the situation.

Note 1 in FIGS. 3 to 6 states that the order of priority may change depending on the depth of sleep of the left rear seat passenger 23 and the front passenger seat passenger 22. Furthermore, Note 2 states that the order of priority may change depending on the depth of sleep of the driver 21 and passenger seat passenger 22. Additionally, Note 3 states that the order of priority may change depending on the depth of sleep of the left rear seat passenger 23 and the driver 21. Note 4 also states that the order of priority may be changed depending on the depth of sleep of the left rear seat occupant 23, driver 21, and passenger seat occupant 22. Furthermore, in Note 5, although the passenger seat 22 is also a target to wake up, the left rear seat passenger 23 is notified immediately.

The configuration of the occupant detection system 100 of this embodiment is as described above, and the operation and effect will be described below with reference to FIG. 7.

The occupant detection system 100 detects the states of a plurality of occupants 20 and supports sleep and wakefulness. For example, the occupant detection system 100 reclines the backrests of the seats 11 to 14 for the occupant 20 who is feeling sleepy. In addition, when it is necessary to wake up the occupant 20, the occupant 20 may be reclined, the vibrating part of the seat belt activated, the seat air conditioner cooled, the seat massage device activated, or a directional speaker, display, etc. The occupant 20 is awakened by communicating this to the occupant 20 (the occupant 20 is awakened using his or her five senses).

The occupant detection system 100 then takes measures when trouble occurs with the occupant 20. The details of the control will be explained below using the flowchart of FIG.

First, in step S100, the instruction control unit 160 monitors the condition of the occupant 20 to see if any trouble has occurred based on the detection data obtained from the detection unit 110. As explained above, troubles include car sickness, sudden abdominal pain, a child crying, or a spilled drink. The instruction control unit 160 determines whether a trouble has occurred based on detection data (images) obtained from the driver monitor 111 and the occupant monitor 112. Note that the instruction control unit 160 determines whether the occupant 20 is awake based on detection data (eye opening, face direction, posture, heart rate, body temperature, etc.) obtained from the driver monitor 111, occupant monitor 112, and biosensor 113. Check whether the person is awake or asleep, looking aside, relaxing or concentrating, etc.

Next, in step S<b>110 , if the instruction control unit 160 determines that a trouble has occurred, the process proceeds to step S<b>120 and grasps the driving scene based on the acquired data from the acquisition unit 120 .

Next, in step S130, the instruction control unit 160 determines whether or not the driver 21 is included when selecting the occupant 20 who should be treated in response to the occurrence of the trouble. Based on the acquired data from the acquisition unit 120, the instruction control unit 160 determines whether the occupant 20 to be treated The driver 21 is included as follows. Further, the instruction control unit 160 does not include the driver 21 as the occupant 20 to be treated in a situation where the second task is not permitted (automatic driving level 2 or lower).

In step S130, if an affirmative determination is made, that is, if it is determined that the driver 21 is included as the occupant 20 to be treated, the instruction control unit 160 proceeds to step S140, and determines whether or not there is a signal from the input unit 130. Determine whether

If a negative determination is made in step S140 (no signal), the instruction control unit 160 moves to step S150 and detects the attributes of the occupant 20 (mainly, whether it is an adult or a child). The instruction control unit 160 detects the attributes of the occupant 20 from detection data (image) obtained from the detection unit 110 (driver monitor 111, occupant monitor 112). Here, it is detected that the driver 21, the passenger 22, and the left rear seat person 23 are adults, and the right rear seat person 24 is a child.

Next, in step S160, the instruction control unit 160 selects a person suitable for handling the trouble from the selection maps shown in FIGS. 3 to 6. For example, as shown in FIG. 3, while driving on a general road, the instruction control unit 160 determines that when a problem occurs with the right rear seat passenger 24 (child), the driver 21, the front passenger seat 22, and the left rear seat passenger 23 are asleep. If not, a suitable person is selected in the priority order of left rear seat person 23>passenger seat person 22>driver 21.

Next, in step S170, if the selected appropriate person is sleeping, the instruction control unit 160 activates the wake-up unit 140 corresponding to the appropriate person (selected person) for a predetermined period of time, Awaken the appropriate person to respond.

Then, in step S180, it is determined whether or not the appropriate person has woken up. If it is determined that the appropriate person has woken up, in step S190, the instruction unit 150 is used to instruct the appropriate person (only the appropriate person). , gives a response instruction (please take ○○ action for the right rear seat passenger 24), and ends this flow.

In step S180, if the appropriate person is not awakened, the instruction control unit 160 proceeds to step S200 and determines whether the awakening operation is the third or more time.

When the awakening operation is performed for the second time, the instruction control unit 160 returns to step S170 and repeats steps S170 and S180 (repeats the operation of the awakening unit 140). Moreover, if the awakening operation is the third time or more, the instruction control unit 160 returns to step S160, restarts from the selection of a suitable person, and executes steps S170 and S180.

Here, if an affirmative determination is made in step S140 (signal present), the instruction control section 160 proceeds to step S210, and determines whether the signal from the input section 130 is the treatment signal from the first input section 131 or the second signal. It is determined whether the request signal is from the input section 132.

If the signal is a treatment signal, the instruction control unit 160 ends this flow. In other words, when there is a treatment signal from the first input unit 131, the person suitable for responding is the crew member 20 who input the treatment signal, so the instruction control unit 160 selects the person suitable for handling (step S160), The wake-up process (step S170) when the appropriate person is sleeping, and furthermore, the instruction on the content of the troubleshooting (step S190) is not performed.

Further, if the signal is a request signal, the instruction control unit 160 moves to step S170. In other words, if there is a request signal from the second input unit 132, it means that a suitable person has been designated, so the instruction control unit 160 does not select a suitable person (step S160), but instead If necessary, an awakening process (step S170) is performed, and in step S190, an instruction is given as to what to do for the trouble (please take ○○ action for the right rear seat passenger 24).

On the other hand, if the above step S130 makes a negative determination, that is, if it is determined that the driver 21 is not included when selecting a person suitable for responding to the occurrence of trouble (if the second task is not permitted), the instruction control unit 160 Then, the process moves to step S220.

In step S220, since the driver 21 must concentrate on driving, if the image data from the driver monitor 111 indicates that the driver 21 is feeling drowsy or looking away, for example, the driver 21 is given a warning and awakened (DSM awakening support).

Then, in step S230, the instruction control unit 160 executes the same control as steps S140 to S210 described above, with the exception of the driver 21 as the appropriate person.

As described above, in this embodiment, the detection unit 110 detects the attributes and states of the plurality of occupants 20. Then, when the detection unit 110 detects a trouble of one of the plurality of occupants 20, the instruction control unit 160 determines the appropriate response to the trouble based on the attributes and conditions of the other occupants 20. The designated person will be selected and will give instructions regarding the measures to the appropriate person. Therefore, even if a trouble occurs with the occupant 20, instructions are given only to the selected appropriate person to deal with the trouble, so that appropriate measures can be taken while maintaining the comfort of the other occupants 20 as much as possible.

In addition, the instruction control unit 160 selects a suitable person to respond and gives instructions regarding treatment based on the driving scene in addition to the attributes and condition of the occupant 20, so that a more appropriate person can be selected. becomes possible.

Further, the instruction control unit 160 is provided with a selection map in advance for selecting a suitable person to deal with the problem based on the plurality of occupants 20, driving scenes, and predicted troubles, and selects a person suitable to deal with the problem from the selection map. This allows the instruction control unit 160 to easily select a suitable person.

In addition, the selection map has predefined priorities for selecting the most suitable person to respond, broadening the scope of selection and making selection easier.

The system also includes a first input section 131 that inputs an input to the effect that the other crew members 20 will take appropriate measures when they detect trouble. Prohibits selection of persons and instructions regarding treatment. As a result, if the occupant 20 himself/herself expresses his/her intention to respond, the control related to selection of a suitable person to respond and treatment instructions can be omitted.
