[0114] In the seat control device 91, the processor 91A has the function of communicating with the vehicle control device 17 via the communication interface 91E. The processor 91A also has the function of communicating with the wearable terminal 101 via the communication interface 91E. The processor 91A controls the vibration device 81 by executing control programs stored in the non-volatile memory 91B and storage 91D.

[0115] The wearable device 101 includes a processor 101A, memory 101B, communication interface 101C (communication I / F), touch panel 101D, and heart rate sensor 101E.

[0116] In the wearable terminal 101, the processor 101A has the function of communicating with the vehicle control device 17 via the communication interface 101C. The processor 101A has the function of communicating with the seat control device 91 via the communication interface 101C. The processor 101A has the function of communicating with an external device via the communication interface 101C.

[0117] In the wearable device 101, the heart rate sensor 101E acquires information related to the driver's heart rate. For example, the heart rate sensor 101E is an optical heart rate sensor equipped with a light-emitting element that irradiates light toward the driver's skin and a photodiode that detects the intensity of the reflected light. In this case, the heart rate sensor 101E detects a waveform that indicates the intensity of the reflected light detected by the photodiode. This waveform reflects the changes in blood flow caused by the heartbeat. The heart rate sensor 101E may also be a sensor using the Doppler effect with radio waves or a sensor using a piezoelectric element.

[0118] The processor 101A, acting as a heart rate measurement device, measures heart rate by performing time-series analysis of the waveform acquired by the heart rate sensor 101E. For example, the processor 101A acquires heart rate information by obtaining the time interval from one peak to the next in the waveform output from the heart rate sensor 101E.

[0119] For example, when a driver is tense or excited, their heart rate increases. Conversely, when a driver's level of alertness decreases, their heart rate decreases. Memory 101B holds thresholds for determining these driver states. For example, memory 101B holds lower and upper heart rate limits (hereinafter referred to as lower heart rate limits) suitable for driving operations.

[0120] The lower heart rate threshold is set as the heart rate threshold at which the driver's level of alertness and concentration may be low. The upper heart rate threshold is set as the heart rate threshold at which the driver may be too excited, potentially causing delays in driving operations, or impairing the driver's judgment and cognitive abilities.

[0121] If the wearable device 101 is constantly worn by the driver, the processor 101A may estimate the lower and upper heart rate limits based on the standard heart rate acquired by the heart rate sensor 101E and record them in the memory 101B. Alternatively, the processor 101A may estimate the lower and upper heart rate limits based on the driver's input of age, blood pressure, body size, etc., on the touch panel 101D and record them in the memory 101B. In these cases, the lower and upper heart rate limits are set to values ​​unique to each driver. This allows for a more appropriate determination of the driver's condition.

[0122] The lower and upper heart rate limits may be set based on standard values ​​for a healthy person. In this case, the lower and upper heart rate limits may be stored in memory 101B at the time of factory shipment or when various applications are installed. The processor 101A may also communicate with various servers (not shown) via the communication interface 101C to obtain the lower and upper heart rate limits and record them in memory 101B.

[0123] In the vehicle, the seat control device 91 acquires the driver's heart rate in real time from the wearable terminal 101. If the driver's heart rate is outside a preset acceptable range, the seat control device 91 operates the vibration device 81 until the driver's heart rate falls outside the acceptable range, thereby guiding the driver's heart rate.

[0124] In this case, the seat control device 91 uses a digital-to-analog converter 91F to convert the digital signal output from the processor 91A into an analog voltage, thereby controlling the amplitude and frequency of the vibration output by the corresponding vibrator 81A.

[0125] For example, the seat control device 91 uses the upper heart rate value obtained from the wearable terminal 101 as the first threshold. If the driver's heart rate is higher than the first threshold, the seat control device 91 controls the vibration device 81 to lower the driver's heart rate. Specifically, the seat control device 91 vibrates the vibrator 81A at a frequency slower than the current heart rate.

[0126] In this case, the vibration device 81 functions as a heart rate induction device that induces fluctuations in the driver's heart rate. Specifically, the vibration device 81 slows down the driver's heart rate, thereby resolving situations where the driver is overexcited, causing delays in driving operations or a decline in the driver's judgment and cognitive abilities, and guiding the driver to a state suitable for driving.

[0127] For example, the seat control device 91 uses the lower limit of the heart rate obtained from the wearable terminal 101 as the second threshold. If the driver's heart rate is lower than the second threshold, the seat control device 91 controls the vibration device 81 to increase the driver's heart rate. Specifically, the seat control device 91 vibrates the vibrator 81A at a frequency faster than the current heart rate.

[0128] In this case, the vibration device 81 functions as a heart rate induction device that induces fluctuations in the driver's heart rate. Specifically, the vibration device 81 increases the driver's heart rate, thereby eliminating a state in which the driver is not fully alert and not fully focused, and guiding them to a state suitable for driving.

[0129] However, in this embodiment, as a general rule, the operation of the vibration device 81 is prohibited when the vehicle is moving through the highway merging area 111. The highway merging area 111 will be described below.

[0130] As shown in Figure 4, the highway merging area 111 includes the main lane 112 and the merging lane 113. The main lane 112 is the primary lane for long-distance travel. The merging lane 113 is the lane for entering the main lane 112. The merging lane 113 includes the acceleration area 113A. The acceleration area 113A is the area adjacent to the main lane 112.

[0131] In this embodiment, the main line 112 includes a first lane 112A and a second lane 112B. The first lane 112A is the lane adjacent to the acceleration area 113A. For example, the second lane 112B is the lane adjacent to the first lane 112A on the opposite side from the acceleration area 113A.

[0132] Although not shown in the diagram, when the vehicle is moving in a location other than the merging area 111, the seat control device 91 controls the vibration device 81 based on pre-set conditions. On the other hand, when the vehicle is moving in the merging area 111, the seat control device 91 generally prohibits the vibration device 81 from operating.

[0133] The following describes an example of the control process for the heart rate induction device performed by the seat control device 91, with reference to a flowchart. The processor 91A repeats this control process while the vehicle is running.

[0134] As shown in Figure 5, in step ST1, the processor 91A determines whether the vehicle is moving through the merging area 111.

[0135] If step ST1 determines that the vehicle is not moving through the merging area 111, step ST2 is executed. In step ST2, the processor 91A determines whether the driver's heart rate is higher than the first threshold.

[0136] If the heart rate is determined to be below the first threshold in step ST2, step ST3 is executed. In step ST3, processor 91A does not operate the vibration device 81. Then, step ST1 is executed.

[0137] If step ST2 determines that the heart rate is higher than the first threshold, step ST4 is executed. In step ST4, processor 91A operates the vibration device 81 to lower the driver's heart rate. Then step ST1 is executed.

[0138] If step ST1 determines that the vehicle is moving through the merging area 111, step ST5 is executed. In step ST5, processor 91A prohibits the vibration device 81 from operating.

[0139] After step ST5, step ST6 is executed. In step ST6, the processor 91A determines whether the vehicle has moved a predetermined distance away from the merging area 111.

[0140] If step ST6 determines that the vehicle is not a predetermined distance away from the highway merging area 111, step ST7 is executed. In step ST7, the processor 91A determines whether or not a moving object has been detected.

[0141] If no moving object is detected in step ST7, step ST8 is executed. In step ST8, the processor 91A maintains a state in which the vibration device 81 is prohibited from operating.

[0142] If a moving object is detected in step ST7, step ST9 is executed. In step ST9, the processor 91A releases the state that prohibits the vibration device 81 from operating.

[0143] After step ST8 or step ST9, step ST6 is executed.

[0144] If step ST6 determines that the vehicle has moved a predetermined distance from the highway merging area 111, step ST10 is executed. In step ST10, the processor 91A releases the state that prohibits the vibration device 81 from operating. Then, step ST1 is executed.

[0145] According to the first embodiment described above, when the vehicle is moving through the merging area 111, the operation of the vibration device 81 is prohibited. This provides an appropriate method for inducing the driver's heart rate. In the merging area 111, where cutting in and lane changes are likely to occur, the operation of the vibration device 81 does not distract the driver. As a result, the driver can maintain a moderate level of concentration.

[0146] For example, when a vehicle is moving through the acceleration area 113A in the merging area 111, the vibration device 81 does not operate. Therefore, when a vehicle is merging onto the main line 112, the driver can maintain a reasonable level of concentration.

[0147] For example, when a vehicle is moving on the main line 112 in the merging area 111, the vibration device 81 does not operate. Therefore, in situations where other moving objects are likely to cut in front of the vehicle, the driver can maintain a reasonable level of concentration.

[0148] For example, when a vehicle is moving in the first lane 112A adjacent to the acceleration area 113A within the main lane 112 in the merging area 111, the vibration device 81 does not operate. Therefore, in situations where other moving objects are likely to cut in front of the vehicle, the driver can maintain a reasonable level of concentration.

[0149] For example, if a vehicle is moving in the second lane 112B adjacent to the first lane 112A on the opposite side of the acceleration area 113A within the main lane 112 in the merging area 111, the vibration device 81 will not operate. Therefore, in situations where another first moving vehicle enters the first lane 112A from the acceleration area 113A, and there is a possibility that the second moving vehicle may change lanes from the first lane 112A to the second lane 112B, the driver can maintain a reasonable level of concentration.

[0150] Furthermore, if the vehicle is moving in the first lane 112A adjacent to the acceleration area 113A within the main lane 112 in the merging area 111, and after the operation of the vibration device 81 has been prohibited, the prohibition on the operation of the heart rate induction device is lifted. This allows the driver to be guided into a state suitable for driving when other moving objects are present nearby.

[0151] Furthermore, if the vehicle is moving in the first lane 112A adjacent to the acceleration area 113A within the main line 112 in the merging area 111, and no other moving objects are detected after the operation of the vibration device 81 has been prohibited, the prohibition on the operation of the vibration device 81 may be lifted. In this case, the driver can be guided to a state suitable for driving when no other moving objects are present nearby.

[0152] Furthermore, if the vehicle is moving through the merging area 111 and the operation of the vibration device 81 has been prohibited, the prohibition on the operation of the vibration device 81 is lifted when the vehicle moves a predetermined distance away from the merging area 111. This allows the driver to be guided to a state suitable for driving outside the merging area 111.

[0153] Furthermore, the vibration device 81 is installed in the vehicle seat. This makes it easy to guide the driver into a state suitable for driving.

[0154] Furthermore, a vibration device mounted on the wearable terminal 101 may be used as a heart rate induction device. In this case, even in vehicles where the vibration device 81 is not provided, the driver can be easily guided to a state suitable for driving.

[0155] Furthermore, instead of the heart rate sensor 101E of the wearable terminal 101, a heart rate sensor provided on the front seat 2 may be used as the heart rate measurement device.

[0156] Furthermore, if the position information acquisition device 15 is unable to receive radio signals from the satellite, it is not necessary to disable the operation of the vibration device 81.

[0157] Furthermore, if the location information acquisition device 15 is unable to receive radio signals from the satellite, the operation of the vibration device 81 may be prohibited until the location information acquisition device 15 is able to receive radio signals.

[0158] Furthermore, a third threshold may be set that is smaller than the first threshold and larger than the second threshold. In this case, if the vehicle is moving through the merging area 111 and the driver's heart rate decreases after the operation of the vibration device 81 has been prohibited, the prohibition on the operation of the vibration device 81 may be lifted.

[0159] Alternatively, the heart rate induction device may induce the driver to relax by rocking the front seat 2 like a cradle.

[0160] (Second Embodiment) In the second embodiment, the conditions for prohibiting the operation of the vibration device 81 differ from those in the first embodiment. The differences from the first embodiment will be mainly described below.

[0161] Figure 6(A) shows a case where a vehicle overtakes another moving object. In this case, as indicated by the arrow, the vehicle changes lanes while moving behind the other moving object in the same lane, and then moves in front of the other moving object.

[0162] Figure 6(B) shows a case where a vehicle overtakes another moving object. In this case, as indicated by the arrow, the vehicle moves in a different lane from the other moving object, passing behind it, and then moves in front of it without changing lanes.

[0163] In the second embodiment, when the vehicle overtakes or passes another moving object, if the vehicle's acceleration is greater than a preset first acceleration threshold, the operation of the vibration device 81 is prohibited as a general rule.

[0164] For example, overtaking or passing another moving object is determined by the vehicle control device 17 based on the detection result of the moving object detection device 16. For example, the acceleration of the vehicle is determined by the vehicle control device 17 based on the location information detection result of the location information acquisition device 15.

[0165] An example of the control process for the heart rate induction device performed by the seat control device 91 will be explained with reference to a flowchart. The processor 91A repeats this control process while the vehicle is running.

[0166] As shown in Figure 7, in step ST11, the processor 91A determines whether the vehicle's acceleration is greater than the first acceleration threshold.

[0167] If step ST11 determines that the vehicle's acceleration is below the first acceleration threshold, step ST12 is executed. In step ST12, the processor 91A determines whether the driver's heart rate is higher than the first threshold.

[0168] If the heart rate is determined to be below the first threshold in step ST12, step ST13 is executed. In step ST13, processor 91A does not operate the vibration device 81. Then, step ST11 is executed.

[0169] If the heart rate is determined to be higher than the first threshold in step ST12, step ST14 is executed. In step ST14, the processor 91A operates the vibration device 81 to lower the driver's heart rate. Then, step ST11 is executed.

[0170] If it is determined in step ST11 that the vehicle's acceleration is greater than the first acceleration threshold, step ST15 is executed. In step ST15, the processor 91A prohibits the vibration device 81 from operating. After step ST15, step ST16 is executed. In step ST16, the processor 91A determines whether or not the first moving object has been detected in front of the device within a preset range.

[0171] If the first moving object is not detected in step ST16, step ST17 is executed. In step ST17, the processor 91A releases the state that prohibits the vibration device 81 from operating. Then, step ST11 is executed.

[0172] If the first moving object is detected in step ST16, step ST18 is executed. In step ST18, the processor 91A determines whether the vehicle has overtaken the first moving object.

[0173] If the vehicle has not overtaken the first moving object in step ST18, step ST18 is repeated. If the vehicle has overtaken the first moving object in step ST18, step ST19 is executed. In step ST19, the processor 91A determines whether or not a second moving object has been detected ahead of the first moving object within a predetermined range.

[0174] If the second moving object is not detected in step ST19, step ST20 is executed. In step ST20, processor 91A releases the state that prohibits the vibration device 81 from operating. Then, step ST11 is executed.

[0175] If a second moving object is detected in step ST19, step ST21 is executed. In step ST21, processor 91A maintains a state in which the vibration device 81 is prohibited from operating. Then, step ST22 is executed.

[0176] In step ST22, the processor 91A determines whether the acceleration of the second moving object is less than or equal to a preset second acceleration threshold.

[0177] If the acceleration of the second moving object is less than or equal to the second acceleration threshold in step ST22, step ST23 is executed. In step ST23, the processor 91A operates the voice output device 12 corresponding to the driver's seat. At this time, the voice output device 12, as a notification device, outputs voice information indicating that the second moving object has come to a sudden stop or decelerated suddenly.

[0178] If the acceleration of the second moving object is greater than the second acceleration threshold in step ST22, or if step ST24 is performed after step ST23, step ST24 is executed. In step ST24, the processor 91A determines whether or not the third moving object is approaching from behind.

[0179] If the third mobile object is not approaching from the rear in step ST24, step ST11 is executed. If the third mobile object is approaching from the rear in step ST24, step ST25 is executed. In step ST25, the processor 91A operates the voice output device 12 corresponding to the driver's seat. At this time, the voice output device 12, as a notification device, outputs information in voice indicating that the third mobile object is approaching from the rear. After that, step ST11 is executed.

[0180] Furthermore, the same control procedure as in Figure 7 may be applied when the vehicle overtakes the first moving object.

[0181] According to the second embodiment described above, when the vehicle's acceleration is greater than the first acceleration threshold, the vibration device 81 is prohibited from operating. Therefore, when the driver's heart rate increases due to voluntary actions such as when the vehicle overtakes or passes another moving object, the driver's concentration will not be diminished by the operation of the vibration device 81. As a result, the driver can maintain a moderate level of concentration.

[0182] Furthermore, when the vehicle's acceleration is greater than the first acceleration threshold and the operation of the vibration device 81 is prohibited, the prohibition on the operation of the vibration device 81 is lifted after the vehicle overtakes or passes the first moving object. Therefore, after the vehicle overtakes or passes the first moving object, the driver can maintain a state suitable for driving unrelated to overtaking or passing.

[0183] However, if the second moving object is detected ahead of the first moving object, the operation of the vibration device 81 is kept prohibited. Therefore, the driver can maintain a reasonable level of concentration while overtaking and passing the second moving object.

[0184] Furthermore, the audio output device 12 operates when the acceleration of the second moving object is below the second acceleration threshold. This allows the driver to be notified that the second moving object has come to a sudden stop or has come to a sudden stop.

[0185] Furthermore, if a third mobile object is approaching from behind, the audio output device 12 will activate. This allows the driver to be notified that a third mobile object is approaching from behind.

[0186] Alternatively, instead of the voice output device 12, a heart rate induction device such as the vibration device 81 on the front seat 2 may be used as a notification device.

[0187] (Third embodiment) In the third embodiment, the conditions for prohibiting the operation of the vibration device 81 differ from those in the first embodiment. The differences from the first embodiment will be mainly described below.

[0188] Figure 8 shows examples of road signs. Figure 8(A) is an example of a bus stop sign. Figure 8(B) is an example of a sign indicating the possibility of animals crossing the road. Figure 8(C) is an example of a sign indicating merging traffic.

[0189] In the third embodiment, when the vehicle is moving through an urban area, it is determined whether or not to activate the vibration device 81 based on the type of road sign.

[0190] For example, whether or not a vehicle is moving in an urban area is determined by the vehicle control device 17. For example, the vehicle control device 17, as a movement status device, determines whether or not the vehicle is moving in an urban area based on location information from the location information acquisition device 15 and map information.

[0191] For example, the type of road sign is determined by the vehicle control device 17. For example, the vehicle control device 17, acting as a sign determination device, compares image information from the moving object detection device 16 with pre-stored image information to determine the type of road sign.

[0192] An example of the control process for the vibration device 81 performed by the seat control device 91 will be explained with reference to a flowchart. The processor 91A repeats this control process while the vehicle is running.

[0193] In step ST31, the processor 91A determines whether or not there are road signs around the vehicle. If there are no road signs around the vehicle in step ST31, step ST31 is repeated.

[0194] If road signs are present around the vehicle in step ST31, step ST32 is executed. In step ST32, the processor 91A determines whether the road sign indicates a stopping place for the vehicle.

[0195] If the road sign in step ST32 indicates a stopping place for the vehicle, step ST33 is performed. In step ST33, the processor 91A prohibits the vibration device 81 from operating until a predetermined time has elapsed or the vehicle has traveled a predetermined distance. Then, step ST31 is performed.

[0196] If the road sign in step ST32 is not a sign indicating a place to stop vehicles, step ST34 is performed. In step ST34, the processor 91A determines whether the road sign is a sign indicating the possibility of animals crossing the road.

[0197] If the road sign in step ST34 is a sign indicating the possibility of an animal crossing the road, step ST33 is executed. If the road sign in step ST34 is not a sign indicating the possibility of an animal crossing the road, step ST35 is executed. In step ST35, processor 91A determines whether the road sign is a sign indicating merging traffic.

[0198] If the road sign in step ST35 indicates merging traffic, step ST33 is performed. If the road sign in step ST35 does not indicate merging traffic, step ST31 is performed.

[0199] According to the third embodiment described above, in urban areas, it is determined whether or not to operate the vibration device 81 based on the type of road sign. Specifically, it is determined whether or not to prohibit the operation of the vibration device 81 based on the type of road sign. Therefore, the vibration device 81 can be appropriately controlled in urban areas where there is a possibility of people or other objects suddenly appearing.

[0200] For example, if the road sign is a bus stop or other sign indicating a vehicle stopping place, the operation of the vibration device 81 is prohibited until a predetermined time has elapsed or until the vehicle has traveled a predetermined distance. Therefore, in places where there is a possibility of a person suddenly appearing, the driver can maintain a reasonable level of concentration.

[0201] Furthermore, signs indicating vehicle stopping points may also be signs indicating taxi stands, parking areas, etc. In this case as well, drivers can maintain a reasonable level of concentration in areas where there is a possibility of people suddenly appearing.

[0202] For example, if a road sign indicates the possibility of an animal suddenly appearing, the operation of the vibration device 81 is prohibited until a predetermined time has elapsed or until the vehicle has traveled a predetermined distance. This allows the driver to maintain a reasonable level of concentration in areas where animals may suddenly appear.

[0203] For example, if the road sign indicates merging traffic, the operation of the vibration device 81 is prohibited until a predetermined time has elapsed or until the vehicle has traveled a predetermined distance. This allows the driver to maintain a reasonable level of concentration in places where other moving objects may suddenly appear.

[0204] (Fourth Embodiment) In the fourth embodiment, the conditions for prohibiting the operation of the vibration device 81 differ from those in the first embodiment. The differences from the first embodiment will be mainly described below.

[0205] In the fourth embodiment, the operation of the vibration device 81 is controlled based on the heart rate and emotions of a occupant seated in the front seat 2, etc. For example, the emotion is determined by the vehicle control device 17. For example, the vehicle control device 17, acting as a driver emotion determination device, determines the driver's emotions based on images from the camera 13. Furthermore, if the vehicle is not moving, the operation of the vibration device 81 is prohibited.

[0206] As shown in Figure 10, when the vehicle is not moving and there are occupants in both the front seat 2 and the mid seat 3, the vehicle control device 17 moves at least one of the front seat 2 and the mid seat 3 via the corresponding seat control device 91 so that both seats are closer together. In Figure 10, the vehicle control device 17 moves the mid seat 3 so that both the front seat 2 and the mid seat 3 are closer together.

[0207] As shown in Figure 11, when the vehicle is not moving and there are occupants in both the front seat 2 and the mid seat 3, the vehicle control device 17 may move at least one of the front seat 2 and the mid seat 3 via the corresponding seat control device 91 so that both the front seat 2 and the mid seat 3 face each other. In Figure 11, the vehicle control device 17 rotates the front seat 2 so that both the front seat 2 and the mid seat 3 face each other.

[0208] An example of the control process for the vibration device 81 performed by the vehicle control device 17 will be explained with reference to a flowchart. The processor 17A repeats this control process while the vehicle is running.

[0209] In step ST41, processor 17A determines whether the vehicle is moving or not. If the vehicle is moving in step ST41, step ST41 is repeated.

[0210] If the vehicle is moving in step ST41, step ST42 is executed. In step ST42, processor 17A prohibits the vibration device 81 from operating. Then step ST43 is executed. In step ST43, processor 17A determines whether there are occupants in both the front seat 2 and the mid seat 3.

[0211] If step ST43 determines that there are no occupants in at least one of the front seat 2 and the mid seat 3, step ST41 is executed. If step ST43 determines that there are occupants in both the front seat 2 and the mid seat 3, step ST44 is executed.

[0212] In step ST44, the processor 17A moves either the front seat 2 or the mid seat 3 so that both seats are closer together. Then, step ST41 is performed.

[0213] According to the fourth embodiment described above, the operation of the vibration device 81 is controlled based on the driver's heart rate and the driver's emotions. This suppresses the driver from becoming upset.

[0214] Furthermore, the vibration device 81 is disabled when the vehicle is not moving. Therefore, when the driver or other personnel are away from driving and taking a break, the seated passengers can maintain a comfortable state for resting.

[0215] Furthermore, when the vehicle is not moving and there are occupants in both the front seat 2 and the mid seat 3, at least one of the front seat 2 and the mid seat 3 will move so that both seats are closer together. This allows occupants to be closer to each other, thereby improving communication between them.

[0216] Furthermore, when the vehicle is not moving and there are occupants in both the front seat 2 and the mid seat 3, at least one of the front seat 2 and the mid seat 3 rotates so that both seats face each other. This allows occupants to face each other, thereby improving communication between occupants.

[0217] Furthermore, the determination of emotions may be based on the voice input to the voice input device 14. For example, if there are multiple passengers, or if a passenger is talking to someone outside the vehicle, emotions may be determined based on the volume and content of the voice.

[0218] Furthermore, the seat control in the first to fourth embodiments may be applied to seats other than the front seat 2. Also, the seat control in the first to fourth embodiments may be applied to various types of vehicles, including buses, trucks, trains, ships, etc.

[0219] Furthermore, if a vehicle deviates from its lane and is notified by the audio output device 12, etc., and then deviates from its lane again within a predetermined time, the audio output device 12, etc. may be prohibited from issuing a further notification. In this case, by issuing a strong notification only the first time, it is possible to avoid startling the driver or other passengers unnecessarily. As a result, the mental burden on passengers can be reduced.

[0220] Furthermore, if a vehicle deviates from its lane and is notified by the audio output device 12, etc., and then deviates from its lane again within a predetermined time, the output of the subsequent notification by the audio output device 12, etc., may be reduced compared to the initial notification. In this case, it is possible to inform the occupants that the vehicle is continuing in an undesirable state while avoiding unnecessarily startling the driver, etc.

[0221] Furthermore, if a vehicle deviates from its lane and is notified by the audio output device 12, etc., and then deviates from its lane again within a predetermined time, the output of the subsequent notification by the audio output device 12, etc., may be increased compared to the first notification. In this case, the seated passengers can be reliably notified that the vehicle is continuing in an undesirable state of movement.

[0222] Furthermore, in an aircraft equipped with a front seat 2 similar to that of the first to fourth embodiments, a device for detecting the altitude of the aircraft may be provided, and the operation of the vibration device 81 may be prohibited if it is determined that the aircraft is traveling at an altitude higher than a preset altitude. When the aircraft is flying at an altitude higher than a preset altitude, safety is relatively high. For this reason, unnecessary heart rate guidance can be prohibited for seated passengers.
