Description

[Technical Field]

[0001] The present invention relates to a seating experience system that includes a seat having sensors. [Background technology]

[0002] BACKGROUND ART Conventionally, a vehicle seat is known in which a plurality of pressure sensors are arranged on the seat to detect the seating posture of an occupant (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-65504 Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional vehicle seats only evaluate and indicate the driver's seating posture, which is problematic in that they are not very effective. While the vehicle is moving, vibrations and other factors can cause the seat occupant to become restless, but conventionally, no means have been developed to maintain this restful state.

[0005] Therefore, in order to propose new value for seats, the present invention aims to provide a seat experience system that allows a seat occupant to maintain a resting state when the seat occupant is in a resting state while the vehicle is moving. [Means for solving the problem]

[0006] In order to solve the above problem, the seat experience system of the present invention comprises a seat body installed in a vehicle, a seat having a sensor that acquires biometric information of an occupant on the seat body, and a control unit that acquires the biometric information from the sensor. The control unit can execute a navigation process to guide the vehicle to a destination according to a set route set by the occupant, and when the navigation process is executing route guidance along the set route and it determines that the occupant is in a resting state based on biometric information, it presents a route with a longer travel distance than the set route.

[0007] According to this configuration, when the seat occupant is in a resting state while the vehicle is moving, a route with a longer travel distance than the set route is presented, and the seat occupant can maintain a resting state by selecting the presented route.

[0008] In addition, the control unit may be capable of distinguishing the sleep state of the seated occupant based on biometric information into at least a first sleep state and a second sleep state that is lighter than the first sleep state, and may suggest switching to manual driving mode if the sleep state changes to the second sleep state while the vehicle is traveling in autonomous driving mode.

[0009] According to this configuration, when the vehicle is traveling in automatic driving mode and the occupant's sleep state falls into the second sleep state, a prompt to switch to manual driving mode is displayed, making it easier for an occupant who is more awake than the first sleep state to notice the prompt to switch to manual driving mode.

[0010] In addition, the control unit may be capable of distinguishing the sleep state of the seated occupant based on biometric information into at least a first sleep state and a second sleep state that is lighter than the first sleep state, and may suggest switching to manual driving mode when it determines that a predetermined time has passed since the sleep state became the first sleep state while the vehicle is traveling in autonomous driving mode.

[0011] According to this configuration, when the vehicle is traveling in automatic driving mode, if a predetermined time has passed since the sleep state entered the first sleep state, that is, if the occupant is in a more awake state than the first sleep state, a prompt to switch to manual driving mode is displayed. This makes it easier for an occupant who is in a more awake state than the first sleep state to notice the prompt to switch to manual driving mode, and allows the occupant to drive in an awake state when switching to manual driving mode.

[0012] The sensor may include a breathing sensor that acquires breathing information of the seated occupant, and the control unit may determine the sleeping state of the seated occupant based on the breathing information.

[0013] According to this configuration, the sleeping state of the seated occupant can be determined effectively based on the breathing information.

[0014] The sensor may include an electroencephalogram sensor that acquires electroencephalogram information of the seated occupant, and the control unit may determine the sleeping state of the seated occupant based on the respiratory information and the electroencephalogram information.

[0015] According to this configuration, the sleeping state of the seated occupant is determined based on the respiratory information and the electroencephalogram information, so that the sleeping state of the seated occupant can be determined with high accuracy.

[0016] The sensor may include a pressure sensor that acquires a pressure value from the seated occupant, and the control unit may determine the sleeping state of the seated occupant based on the breathing information and the pressure value.

[0017] According to this configuration, the sleeping state of the seated occupant is determined based on the respiration information and the pressure value, so that the sleeping state of the seated occupant can be determined with high accuracy.

[0018] The seat experience system may further include a server capable of communicating with the control unit, wherein the control unit transmits the biometric information acquired from the sensor to the server together with the identification information of the seat occupant, and the server stores the biometric information transmitted from the control unit together with the identification information.

[0019] According to this configuration, the biometric information of the seated occupant is stored in the server together with the identification information, so that the control unit can perform various processes based on the biometric information stored in the server.

[0020] The control unit may also notify the user of the biological information acquired from the sensor.

[0021] According to this, the control unit notifies the seated person of the biological information, so that the seated person can know his / her own biological information. [Effects of the Invention]

[0022] According to the present invention, when a seat occupant is in a resting state while the vehicle is moving, it is possible to maintain that resting state.

[0023] In addition, by presenting the switch to manual driving mode based on the sleeping state of the occupant, an awake occupant is more likely to notice the switch to manual driving mode, and the occupant can drive in an awake state when switching to manual driving mode.

[0024] Furthermore, by determining the sleeping state of the seated occupant based on the breathing information, the sleeping state of the seated occupant can be determined accurately.

[0025] Furthermore, by determining the sleeping state of the seated occupant based on the respiratory information and the electroencephalogram information, the sleeping state of the seated occupant can be determined with high accuracy.

[0026] Furthermore, by determining the sleeping state of the seated occupant based on the respiration information and the pressure value, the sleeping state of the seated occupant can be determined with high accuracy.

[0027] Furthermore, by storing the seated person's biometric information together with the identification information in the server, the control unit can perform various processes based on the biometric information stored in the server.

[0028] Furthermore, the control unit notifies the seated person of the biological information, allowing the seated person to know the biological information of the seated person. [Brief explanation of the drawings]

[0030] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in Fig. 1, the seat experience system 1 includes a seat S, a control unit 100, and a server SV. The seat S is configured as a vehicle seat installed in a vehicle, which is an example of a vehicle. In the present invention, front, back, left, right, up and down are determined based on the seat occupant P sitting in the seat S.

[0031] The seat S has a seat body S0 installed in a vehicle, and a heart rate sensor 11 and a breathing sensor 12 as examples of sensors. The seat body S0 has a seat cushion S1, a seat back S2, and a headrest S3. The seat cushion S1, the seat back S2, and the headrest S3 each have a cushion pad and a cover covering the cushion pad.

[0032] The heartbeat sensor 11 is a sensor that acquires heartbeat information, which is biological information of the seated occupant P on the seat main body S0. The heartbeat sensor 11 is provided on the back of the surface skin of the seat back S2.

[0033] The breathing sensor 12 is a sensor that acquires breathing information, which is biological information of the seated occupant P. The breathing sensor 12 is provided on the back of the surface skin of the seat back S2.

[0034] The vehicle is equipped with a monitor 21 capable of displaying a screen for guiding the vehicle, and a driving mode switching button 22 for starting or ending the autonomous driving mode of the vehicle. The driving mode switching button 22 is configured to output a start signal for starting the autonomous driving mode when pressed when not in the autonomous driving mode, and to output an end signal for ending the autonomous driving mode when pressed during the autonomous driving mode.

[0035] The control unit 100 has a CPU, ROM, RAM, rewritable nonvolatile memory, etc. (not shown), and has the function of executing pre-stored programs. Specifically, as shown in Figures 2(a) and 2(b), the control unit 100 is capable of executing navigation processing to guide the vehicle to a destination according to a set route set by the seat occupant P operating various operation buttons on the monitor 21.

[0036] More specifically, when the seated person P presses the destination button B2 on the monitor 21, the control unit 100 displays a screen (not shown) for setting the destination on the monitor 21. Once the seated person P sets the destination, the control unit 100 displays multiple routes on the monitor 21 based on the current location of the vehicle and the destination, as shown in FIG. 2(b). When the seated person P selects a specific route from the multiple routes and presses the guidance start button B1, the control unit 100 starts providing route guidance according to the set route set by the seated person P.

[0037] After starting route guidance, the control unit 100 displays a guidance end button B3 shown in Fig. 3(a) instead of the guidance start button B1. Then, when the guidance end button B3 is pressed or when the vehicle arrives at the destination, the control unit 100 ends the navigation process.

[0038] The control unit 100 can also acquire biological information from the heart rate sensor 11 and the respiration sensor 12, and can also acquire a signal for starting and ending the automatic operation mode from the operation mode switching button 22. The control unit 100 then performs various processes based on the acquired information and signals.

[0039] The signal output from the driving mode switching button 22 is acquired by an ECU (Electronic Control Unit) (not shown) mounted on the vehicle, and the ECU executes automatic driving control to automatically drive the vehicle. In the automatic driving control, the ECU executes, for example, a process to drive the vehicle without straying from the driving lane using a sensor such as a camera mounted on the vehicle, and a process to maintain a predetermined distance between the vehicle and a vehicle traveling in front of the vehicle. In this embodiment, the ECU executes automatic driving control based on the signal from the driving mode switching button 22 only when the vehicle is traveling on a highway.

[0040] 3(a) and 3(b), when the control unit 100 determines that the seated occupant P is in a resting state based on heart rate information while providing route guidance along a set route in the navigation process, the control unit 100 has a function of presenting a route with a longer travel distance than the set route. Here, as a method for determining whether or not the seated occupant P is in a resting state, for example, a method for determining that the seated occupant P is in a resting state when the heart rate of the seated occupant P is equal to or lower than a predetermined value may be used. Note that the predetermined value, which is a threshold value for the heart rate, may be set in advance by the seated occupant P so as to be a numerical value corresponding to the seated occupant P, or may be set by the control unit 100 based on heart rate information accumulated in the server SV.

[0041] The control unit 100 can also distinguish the sleep state of the seated occupant P between a first sleep state and a second sleep state, which is lighter than the first sleep state, based on the respiratory information. The sleep state can be determined using the determination method disclosed in Japanese Patent Application Laid-Open Publication No. 2017-80297. Specifically, this determination method acquires the respiratory data of the seated occupant P using a respiratory sensor, calculates P_vel, which is the degree of change in the respiratory data (pressure signal) per unit time, based on the acquired respiratory data, and determines the wakefulness state of the seated occupant P using a Bayes filter that multiplies the likelihood by the prior probability of the seated occupant becoming drowsy regarding P_vel. By using this method, the control unit 100 can determine the wakefulness state as the first sleep state and any state other than the wakefulness state as the second sleep state. Furthermore, as shown in FIGS. 4(a) and 4(b), the control unit 100 has a function of suggesting switching to manual driving mode when the sleep state changes to the second sleep state while the vehicle is traveling in autonomous driving mode.

[0042] The control unit 100 is also capable of communicating with the server SV, and has a function of transmitting the biometric information acquired from the heartbeat sensor 11 and the respiration sensor 12 to the server SV together with the identification information of the seated person P. Here, the identification information can be manually input by the seated person P, for example, on a setting screen displayed on the monitor 21. The server SV has a function of storing the biometric information transmitted from the control unit 100 together with the identification information.

[0043] In addition, the control unit 100 has the function of notifying the seated occupant P of the biometric information acquired from the heart rate sensor 11 by displaying the biometric information on the monitor 21 (see Figures 2(b), 4(a), etc.).

[0044] Next, a detailed description will be given of the operation of the control unit 100. The control unit 100 is capable of executing a navigation process shown in Fig. 5 and a sleep state determination process shown in Fig. 6, which is a process performed during automatic driving control.

[0045] 5, the control unit 100 first determines whether or not the destination and route have been set and the guidance start button B1 has been pressed by the seated occupant P (S11). If it is determined in step S11 that the guidance start button B1 has not been pressed (No), the control unit 100 ends this process.

[0046] If it is determined in step S11 that the guidance start button B1 has been pressed (Yes), the control unit 100 starts route guidance according to the set route set by the seated occupant P (S12). After step S12, the control unit 100 acquires biometric information from the heart rate sensor 11 and the breathing sensor 12 (S13), and transmits the biometric information together with the identification information to the server SV (S14).

[0047] After step S14, the control unit 100 displays the heart rate information acquired in step S13 on the monitor 21 (S15). After step S15, the control unit 100 determines whether the seated person P is in a resting state based on the heart rate information (S16).

[0048] If it is determined in step S16 that the seated occupant P is in a resting state (Yes), the control unit 100 displays a longer, circuitous route than the set route on the monitor 21 (S17). After step S17, the control unit 100 determines whether or not the circuitous route has been selected by the seated occupant P (S18).

[0049] If it is determined in step S18 that a detour route has been selected (Yes), the control unit 100 starts guidance for the detour route (S19). After step S19, or if it is determined No in step S16 or step S18, the control unit 100 determines whether either of the first condition that the destination has been reached or the second condition that the guidance end button B3 has been pressed has been met (S20).

[0050] If it is determined in step S20 that neither the first condition nor the second condition is satisfied (No), the control unit 100 returns to the processing of step S13. If it is determined in step S20 that either the first condition or the second condition is satisfied (Yes), the control unit 100 ends this processing.

[0051] 6, the control unit 100 first determines whether or not the start of the automatic driving mode has been selected by the seated occupant P based on a signal from the driving mode switching button 22 (S41). If it determines in step S41 that the start of the automatic driving mode has not been selected (No), the control unit 100 ends this process.

[0052] If it is determined in step S41 that the start of the sleep state determination process has been selected (Yes), the control unit 100 acquires biological information from the heartbeat sensor 11 and the respiration sensor 12 (S42), and transmits the biological information together with the identification information to the server SV (S43). After step S43, the control unit 100 displays the heartbeat information acquired in step S42 on the monitor 21 (S44).

[0053] After step S44, the control unit 100 determines whether the sleeping state of the seated occupant P is the second sleeping state based on the breathing information (S45). If the sleeping state is determined to be the second sleeping state in step S45 (Yes), the control unit 100 displays a message recommending switching to the manual driving mode (S46).

[0054] Specifically, in step S46, the control unit 100 displays a message on the monitor 21 and generates a sound, such as a voice or an alarm sound, corresponding to the message from the speaker, thereby waking up the seated occupant P. Note that instead of generating a sound, a vibration device provided on the seat S may be vibrated. Alternatively, sound generation and vibration may be combined.

[0055] If the determination in step S46 or step S45 is No, the control unit 100 determines whether or not the end of the autonomous driving mode has been selected based on a signal from the driving mode switching button 22 (S47). If the control unit 100 determines in step S47 that the end of the autonomous driving mode has not been selected (No), the control unit 100 returns to the processing of step S42. If the control unit 100 determines in step S47 that the end of the autonomous driving mode has been selected (Yes), the control unit 100 ends this processing.

[0056] Next, an example of the operation of the control unit 100 will be described in detail. As shown in FIG. 2(a), when the seated person P presses the destination button B2 on the monitor 21, the control unit 100 displays a screen (not shown) on the monitor 21 for setting the destination. Once the seated person P sets the destination, the control unit 100 displays multiple routes on the monitor 21 based on the current location of the vehicle and the destination, as shown in FIG. 2(b). When the seated person P selects a specific route from the multiple routes and presses the guidance start button B1, the control unit 100 starts route guidance according to the set route set by the seated person P, and also displays the heart rate of the seated person P on the monitor 21.

[0057] During navigation processing, the control unit 100 determines whether the seated occupant P is in a resting state based on the heart rate information. If it is determined that the seated occupant P is in a resting state, the control unit 100 displays on the monitor 21 a message urging the seated occupant P to take a detour route and a selection button B4 for selecting the detour route, as shown in FIG. 3(a). Specifically, for example, a message such as "Your body is in a resting state. Why not take a slightly detour and maintain your resting state?" is displayed on the monitor 21. Note that the control unit 100 may be configured to generate a sound, such as a voice or an alarm sound, corresponding to the message from a speaker when displaying the message.

[0058] When the seated person P is prompted by the message to want to maintain a resting state and presses the selection button B4, the control unit 100 starts providing route guidance along a circuitous route, as shown in Fig. 3(a). In this embodiment, the heart rate of the seated person P is displayed on the monitor 21 together with the message urging the seated person P to take a circuitous route, so that the seated person P who sees the message can know whether he or she is truly in a resting state by checking the displayed heart rate.

[0059] 4(a), when the control unit 100 is guiding a vehicle traveling in autonomous driving mode on a highway, the control unit 100 displays the heart rate of the seated occupant P on the monitor 21. During the autonomous driving mode, the control unit 100 determines whether the sleeping state of the seated occupant P is the second sleeping state based on the breathing information.

[0060] When it is determined that the sleeping state of the seated occupant P is the second sleeping state, the control unit 100 displays a message on the monitor 21 urging the seated occupant P to switch to the manual driving mode, as shown in Fig. 4(b). Specifically, for example, a message saying "Your sleep has become lighter, so we recommend that you switch to the manual driving mode now" is displayed on the monitor 21, and a sound such as a voice or an alarm sound corresponding to the message is output from the speaker.

[0061] When the seated occupant P presses the driving mode switching button 22 in accordance with the message, the control unit 100 ends the sleep state determination process, and the ECU ends the automatic driving control.

[0062] Here, when automatic driving control is performed only on expressways, it is desirable to switch to manual driving mode at some point, for example, when getting off at an expressway exit or when stopping at a service area, but if the seated occupant P falls asleep during automatic driving control, it becomes impossible to switch to manual driving mode. Therefore, if the seated occupant P falls asleep, it is possible to wake up the seated occupant P with an alarm sound or the like.

[0063] However, if the seated occupant P is in a deep sleep, the notification sound may not wake the seated occupant P. In contrast, in this embodiment, the control unit 100 notifies the seated occupant P by using a notification sound or the like when the seated occupant P is in a light sleep, so that the seated occupant P can be smoothly switched from the automatic driving mode to the manual driving mode.

[0064] The timing of the suggestion to switch to manual driving mode may be determined taking into consideration the distance from the vehicle's current location to a second destination, such as a highway exit or a service area. For example, the suggestion to switch to manual driving mode can be presented when both the condition that the distance from the vehicle's current location to the second destination is less than a predetermined distance and the condition that the sleep state is a second sleep state are met. The highway exit, which is the second destination, is set by the control unit 100 based on the set route set by the seated occupant P. The service area, which is the second destination, is manually set by the seated occupant P as the second destination when setting the set route.

[0065] As described above, the following effects can be obtained in this embodiment. When the occupant P in the seat S is in a resting state while the vehicle is traveling, a route with a longer travel distance than the set route is presented, and the occupant P can maintain a resting state by selecting the presented route.

[0066] When the vehicle is traveling in the automatic driving mode, if the sleep state of the seated occupant P changes to the second sleep state, a switch to the manual driving mode is presented, so that the seated occupant P who is in a more awake state than the first sleep state can easily notice the presentation to switch to the manual driving mode.

[0067] Since the biometric information of the seated occupant P is stored in the server SV together with the identification information, the control unit 100 can perform various processes based on the biometric information stored in the server SV.

[0068] The control unit 100 notifies the seated occupant P of the biological information, so that the seated occupant P can know his / her own biological information.

[0069] The present invention is not limited to the above-described embodiment, but can be used in various forms as exemplified below.

[0070] In the above embodiment, the driver is prompted to switch to the manual driving mode when the sleep state changes to the second sleep state, but the present invention is not limited to this. For example, when the vehicle is traveling in the autonomous driving mode, the driver may be prompted to switch to the manual driving mode when it is determined that a predetermined time has passed since the driver entered the first sleep state.

[0071] In this case, the control unit 100 may execute, for example, the sleep state determination process shown in Fig. 7. Here, the sleep state determination process shown in Fig. 7 includes steps S41 to S44, S46, and S47 similar to the sleep state determination process shown in Fig. 6, as well as new steps S61 to S65.

[0072] Specifically, after executing the processes of steps S41 to S44, the control unit 100 determines whether the flag F indicating that the sleeping state of the seated occupant P has entered the first sleeping state is 1 (S61). If it is determined in step S61 that F is not 1 (No), the control unit 100 determines whether the sleeping state of the seated occupant P is the first sleeping state (S62). If it is determined in step S62 that the sleeping state is the first sleeping state (Yes), the control unit 100 sets the flag F indicating that the sleeping state has entered the first sleeping state to 1 (S63).

[0073] After step S63, or if the determination in step S61 is Yes, the control unit 100 determines whether a predetermined time has elapsed since the first sleeping state was entered (S64).

[0074] If it is determined in step S64 that the predetermined time has elapsed (Yes), the control unit 100 displays a message recommending switching to the manual driving mode (S46). After step S46, the control unit 100 resets the flag F to 0 (S65) and proceeds to the processing of step S47. Furthermore, if the control unit 100 determines No in step S62 or step S64, it proceeds to the processing of step S47.

[0075] According to this embodiment, when the vehicle is traveling in automatic driving mode, if a predetermined time has passed since the sleep state entered the first sleep state, that is, if the occupant is in a more awake state than the first sleep state, a prompt to switch to manual driving mode is displayed, making it easier for an occupant who is in a more awake state than the first sleep state to notice the prompt to switch to manual driving mode.

[0076] In the above embodiment, the heart rate sensor 11 is used as an example of a sensor for determining the resting state of the seated occupant P, but the present invention is not limited to this and any sensor capable of acquiring biological information for determining the resting state of the seated occupant P may be used. For example, if the pulse of the occupant can be detected by a pressure sensor that detects the load from the occupant, the sensor may be a pressure sensor. Furthermore, the breathing sensor may be a pressure sensor that acquires a pressure value from the seated occupant, or may be a radio wave sensor that emits radio waves toward the seated occupant.

[0077] In the above embodiment, the respiration sensor 12 is exemplified as a sensor for determining the sleep state, but the present invention is not limited to this, and the sensor may be, for example, an electroencephalogram (EEG) sensor that detects the brain waves of the seated occupant. In this case, as a method for determining the sleep state, for example, a method may be used in which a first sleep state is determined when the amplitude of the EEG is equal to or greater than a first threshold, and a second sleep state is determined when the amplitude of the EEG is lower than a second threshold that is equal to or less than the first threshold.

[0078] Furthermore, the sleep state may be determined by using both a breathing sensor and an electroencephalogram sensor. Specifically, when it is determined that the seated person has entered an awake state based on the breathing sensor and the amplitude of the electroencephalogram has become lower than a predetermined threshold, it may be determined that the seated person has entered an awake state (first sleep state).

[0079] Furthermore, the breathing sensor and the pressure sensor may be used together to determine the sleep state. Specifically, when it is determined that the seated person has entered an awake state based on the breathing sensor and a body movement greater than or equal to a predetermined value (a change in pressure value greater than or equal to a predetermined value) is observed by the pressure sensor, it may be determined that the seated person has entered an awake state (first sleep state).

[0080] The biological information displayed on the monitor is not limited to heart rate information, but may also include respiratory information, brain wave information, and the like.

[0081] In the above embodiment, a vehicle is used as an example of a vehicle, but the present invention is not limited to this, and other vehicles such as a ship or an aircraft may also be used.

[0082] The elements described in the above-described embodiment and modified examples may be implemented in any combination. [Explanation of symbols]
