Further, the arrangement of the motion sickness countermeasure device 100 is not limited to the rear of the seat 202, and may be arranged at other positions such as a trunk room.

  In FIG. 2, the camera 205 constituting the detection means 11 captures the passenger's face color, line of sight, eye shape, facial expression, blink, movement, etc., so that information on the passenger's state is detected, and the state information processing means 12 Thus, information processing such as image processing is performed, and information on the passenger's face color, line of sight, eye shape, facial expression, blink, movement, etc. is digitized. Similarly, information related to body temperature is detected by the infrared camera 206, information processing such as image processing is performed by the state information processing means 12, and information related to the body temperature of the passenger is digitized.

  The sensor that constitutes the detection means 11 detects a passenger's movement and physiological change, detects information related to the passenger's body temperature, heart rate, breathing, sweating, posture, etc., for example, as a digital signal It is designed to output. Specifically, information on heart rate and respiration is measured by a measuring device attached to the seat belt 203.

The passenger status information generated by the passenger status detection unit 10 as described above is output from the motion sickness determination unit 30 to the data processing storage unit 40 as shown in FIG.

  The vehicle state detection unit 20 includes a temperature sensor, a humidity sensor, a vibration detection sensor, and the like, and detects information related to the state of the vehicle such as travel of the vehicle, temperature and humidity in the vehicle, and the like. For example, the vehicle state detection unit 20 starts detection when the engine is started, detects information related to the state of the vehicle via a temperature sensor, a humidity sensor, a vibration detection sensor, and the like disposed on the vehicle, for example, as a digital signal It is designed to output. Hereinafter, the vehicle state detection unit 20 outputs a digital signal, and information transmitted by the digital signal is referred to as vehicle state information.

  Sensors that detect information related to the state of the vehicle are not limited to temperature sensors, humidity sensors, and vibration detection sensors, and may be other sensors that can detect information related to the state of the vehicle. Further, the timing for starting detection is not limited to when the engine is started, and may be other timing even after traveling for a certain time.

  The motion sickness determination unit 30 is based on passenger state information output from the passenger state detection unit 10, vehicle state information output from the vehicle state detection unit 20, and information stored in the data processing storage unit 40. It is determined whether or not the passenger is in motion sickness. If the data processing storage unit 40 is not provided, it is determined whether or not the passenger is in motion sickness from one or more prepared thresholds.

  Next, the data processing storage unit 40 will be described.

  The data processing storage unit 40 is predetermined information among the passenger state information output from the passenger state detection unit 10 and the vehicle state information (hereinafter referred to as detection information) output from the vehicle state detection unit 20. Is stored in the hourly data storage means 43. Here, the hourly data storage means 43 may be configured to identify and store the detection information for each passenger.

  The data processing storage unit 40 is also configured to store vehicle state information such as temperature and humidity in the vehicle output from the vehicle state detection unit 20 in the vehicle data storage means 41.

  Further, the data processing storage unit 40 determines whether the passenger is in motion sickness based on the passenger state information stored in the hourly data storage unit 43 and the vehicle state information stored in the vehicle data storage unit 41. A motion sickness determination threshold value used as a reference for determining whether or not (hereinafter simply referred to as motion sickness determination) is calculated and stored in the feature data storage means 42.

  For example, when the body temperature is measured by the sensor as the detection unit 11, the data processing storage unit 40 determines the range of the passenger's body temperature when the person is not in motion sickness based on the measured value of the passenger's body temperature. The body temperature at the upper and lower boundaries that define the determined body temperature range is stored in the feature data storage means 42 as a motion sickness determination threshold. The body temperature range of the passenger when not in motion sickness is calculated within a predetermined time immediately after acquiring the passenger state information and stored in the data processing storage unit 40. It may be stored.

  The data processing storage unit 40 includes information related to motion sickness in the past, such as detection information when a motion sickness has occurred in the past, information on a motion sickness determination threshold, information on countermeasures taken by the countermeasure 50, and the like (hereinafter, Simply referred to as motion sickness information) may be stored in the feature data storage means 42. In this case, out of the detection information when the motion sickness state has been caused in the past, the detection information that has been determined to be the motion sickness state may be stored in the feature data storage means 42.

  In the data processing storage unit 40, a motion sickness determination threshold is determined for each individual based on detection information output from the passenger state detection unit 10 and the vehicle state detection unit 20, and is stored in the feature data storage unit 42. However, in a predetermined case, the motion sickness determination threshold value may be determined based on the passenger state information.

  For example, when the body temperature measured by the sensor has a data processing storage unit 40 and the body temperature measured by the sensor is not in the motion sickness state, the upper and lower body temperatures that define the range of the body temperature of the passenger are the motion sickness determination threshold values. , The motion sickness determination unit 30 is out of the range of the passenger's body temperature when the passenger's body temperature is not in the motion sickness state based on the passenger state information output from the passenger state detection unit 10. When it becomes, it determines with it being motion sickness, and the countermeasure part 50 takes countermeasures.

  Hereinafter, regarding detection information obtained as numerical data, a motion sickness determination threshold value is calculated within a predetermined time after the engine is started and stored in the data processing storage unit 40. When information on the posture is targeted, a signal indicating that the posture is bent forward based on the information from the pressure sensor 207 (hereinafter referred to as a forward bending signal) is output by the state information processing means 12, and the forward bending signal is output. When continuing for a predetermined time or more, it is determined that the person is in a motion sickness state.

  In the case of targeting information related to sweating, a determination method based on detection information from a humidity sensor as the detection means 11 and information on the temperature, humidity, etc. in the vehicle obtained from the vehicle state detection unit 20, and There is a method of determining that the person is in a motion sickness state because the physical condition has deteriorated when a sweat component different from the component detected in a normal state is detected using means capable of detecting the sweat component.

  Furthermore, when acquiring a passenger | crew's image | video using the camera 205, the state information processing part 12 analyzes one or more predetermined parts of a passenger, and the value digitized for every part of analysis object is obtained. The data is output to the hourly data storage means 43 of the data processing storage unit 40. As for the face color, the face color is digitized by a predetermined method to determine a motion sickness determination threshold related to the face color, stored in the feature data storage means 42 of the data processing storage unit 40, and the face color stored in the feature data storage means 42. Based on the motion sickness determination threshold, it is determined that the face color is red or blue.

  Here, since the face color often depends on the temperature and humidity in the vehicle, the motion sickness determination based on the information about the face color is also applied to data such as the temperature and humidity in the vehicle stored in the vehicle data storage means 41. It may be based on. Further, the line of sight, the shape of the eyes, and the facial expression are determined based on changes in the feature points by detecting the feature points and storing them in the feature data storage means 42.

  For blinking, based on information regarding the number of blinks within a predetermined time output from the state information processing unit 12, information on a motion sickness determination threshold value for the number of blinks is generated and stored in the feature data storage unit 42; The motion sickness determination may be performed based on the information on the number of blinks output from the state information processing unit 12 and the information on the motion sickness determination threshold of the number of blinks stored in the feature data storage unit 42.

  In the above, the method of generating the motion sickness determination threshold for each passenger has been described, but the method is not necessarily limited to this method, and the motion sickness determination may be performed using a common magnification as the motion sickness determination threshold. Good. In this method, after the engine is started, the passenger state information first detected by the passenger state detection unit 10 and the vehicle state information first detected by the vehicle state detection unit 20 are associated with each other, and the detection value is determined in advance. The vehicle motion sickness determination threshold value is calculated based on the information stored in the feature data storage unit 42 and stored in the feature data storage unit 42 to perform vehicle motion sickness determination. In this method, since it is not necessary to calculate the passenger state information output from the passenger state detection unit 10 every time detection is performed, the processing load can be reduced.

  In addition, the data processing storage unit 40 is provided with a learning function, and the vehicle state information output from the vehicle state detection unit 20 and information obtained by learning the rider's past motion sickness information are stored in the feature data storage unit 42. The motion sickness determination may be performed based on the vehicle state information and the motion sickness information. Hereinafter, a method for performing motion sickness determination by giving the data processing storage unit 40 a learning function as described above will be described.

  First, as a first method, a passenger who is in motion sickness presses a button (hereinafter referred to as “motion sickness button”) himself, and the detection information regarding the state when the motion sickness button is pressed is stored in the data processing storage unit 40. There is a method of learning based on the stored detection information. This is because a passenger who thinks that he / she is in motion sickness presses a motion sickness button provided on the vehicle, stores the detection information at that time in the data processing storage unit 40, and based on the stored detection information The motion sickness determination threshold determined in this way is stored in the feature data storage means 42 and used later by the motion sickness determination unit 30.

  Note that each time the motion sickness button is pressed by the passenger, the detection information is output to the data processing storage unit 40, and the data processing storage unit 40 performs learning based on the detection information to set the motion sickness determination threshold value. It is assumed that the updated result and the updated result are stored in the feature data storage means 42.

  As a second method, after the engine is started, detection information is stored and accumulated in the hourly data storage means 43 of the data processing storage unit 40 every predetermined time, and the detection information stored in the hourly data storage means 43 is accumulated. There is a method in which information is learned to determine a motion sickness determination threshold and stored in the feature data storage means 42 to be used for motion sickness determination. In this method, detection information is stored in the data processing storage unit 40 and accumulated every predetermined time, so that it is possible to make a motion sickness determination in detail.

  As a third method, there is a method of learning the characteristics of a vehicle and using it for motion sickness determination. The third method can be used when the learning function can be used in a plurality of vehicles, and is used by storing the information stored in the feature data storage means 42 in a portable storage medium. . By using a vehicle equipped with a motion sickness countermeasure device that can use the learning function and transmitting information via the portable storage medium described above, any vehicle can use the motion sickness information of the passenger, and the vehicle state The motion sickness determination can be performed based on the vehicle state information output from the detection unit 20.

  Note that the detection means 11 includes one or more of means such as a camera, an infrared camera, and a sensor. The operation when the detection means 11 has a plurality of means is performed as follows. When it is determined that the occupant is in motion sickness based on a signal detected through one of the plurality of means, detection information is stored in the data processing storage unit 40 from the motion sickness determination unit 30, It is learned by the data processing storage unit 40, and the motion sickness state is detected early for each individual. When the motion sickness state is detected, the countermeasure unit 50 takes countermeasures to reduce the degree of motion sickness. Thus, by learning, a detection method suitable for the passenger can be found.

  In addition, based on the detection information stored in the vehicle data storage means 41 and the motion sickness determination threshold value stored in the feature data storage means 42, the degree of motion sickness is quantified, and the countermeasure unit 50 is used as the degree of motion sickness information. It may be output to. Note that the motion sickness determination method is not limited to the above method, and other methods may be used.

  When the motion sickness determination unit 30 determines that the motion sickness state is present, the countermeasure unit 50 takes measures to reduce the degree of motion sickness, but the motion sickness output from the motion sickness determination unit 30 Based on the degree information, the above countermeasures may be taken. Countermeasures include opening a window to allow outside air, adjusting the temperature and humidity in the vehicle, and increasing the oxygen concentration in the vehicle. These countermeasures are adjusted with reference to data of the vehicle state detection unit 20 before the motion sickness starts.

  As a countermeasure, it is also possible to play a relaxing music prepared in advance. Furthermore, the driver may be notified of the presence of a passenger who is in motion sickness using a warning sound, voice, display, or the like. In addition, when the degree of motion sickness information is included in the output from the motion sickness determination unit 30, a necessary amount of measures are taken according to the degree of motion sickness information.

  In the above description, the case where the motion sickness countermeasure device 100 includes the data processing storage unit 40 and has a configuration for determining the motion sickness state based on the motion sickness determination threshold stored in the data processing storage unit 40 has been described. Based on the passenger state information and vehicle state information output from the passenger state detection unit 10 and the vehicle state detection unit 20, the motion sickness determination unit 30 determines whether or not the passenger is in a motion sickness state. When it is determined that is in a motion sickness state, the countermeasure unit 50 may take a countermeasure measure to reduce the degree of motion sickness. In this configuration, the data processing storage unit 40 is not required, and the motion sickness determination unit 30 may hold the motion sickness determination threshold in advance. Further, it may be possible for an occupant to switch whether or not to take countermeasures by the countermeasure unit 50 using a switch (not shown).

  As described above, in the motion sickness countermeasure device according to the embodiment of the present invention, the passenger state detection unit detects the state of the passenger in the vehicle, and the motion sickness determination unit is detected by the passenger state detection unit. Based on the information, it is determined whether or not the passenger is in motion sickness, and the countermeasures detect motion sickness based on behavior and physiological changes to reduce the level of motion sickness, and the degree of motion sickness Can be reduced.

  In addition, since the detection means is embedded in a predetermined position of the vehicle, the passenger can detect motion sickness only by sitting on the seat without wearing any device, and the presence of the device in the passenger Can not be conscious.

  In addition, since the passenger state detection unit has state information processing means for performing predetermined information processing on the video of the passenger of the vehicle and digitizing information related to the state of the passenger, complicated processing such as image data is required. It is also possible to acquire information on motion sickness from the information.

  Further, the motion sickness determination unit determines whether the passenger is in a motion sickness state based on the passenger state information stored in the data processing storage unit, vehicle state information, and information on the motion sickness determination threshold.
