JP2009-251687A

The motion sickness reduced in Patent Document 1 is so-called “motion sickness”. In general, the cause of motion sickness is vibration during movement, which is one of the characteristics of the vehicle itself. In particular, it is known that a relatively gentle vibration of about once every 3 seconds tends to induce motion sickness. On the other hand, in a vehicle which is an example of a vehicle, “about once every 3 seconds of vibration” is vibration that improves ride comfort. For this reason, it is common to use a soft spring material for the elastic member used in the suspension device provided in the vehicle so as to generate a comfortable vibration. That is, particularly in the case of a vehicle, setting a suspension device with an emphasis on ride comfort provides an environment in which motion sickness is likely to be induced. In particular, if the passenger is in a state of staring at a specific position with a relatively close viewpoint, such as watching TV while riding the vehicle, the likelihood of motion sickness is further increased. Therefore, even if the background image is devised as in Patent Document 1, it is not possible to effectively prevent motion sickness unless a factor that induces motion sickness is suppressed in relation to vibration transmitted to the passenger.

In order to prevent such motion sickness induction, the vibration characteristics of the vehicle may be changed according to the situation of the passenger. Specifically, it is only necessary to change the setting of a suspension that constitutes a suspension device that includes a spring and a damper that supports the vehicle, and to increase the frequency of vibration of the vehicle.

An object of the present invention is to provide a portable terminal device that detects that a user is prone to motion sickness and changes the characteristics of the vehicle to a state in which motion sickness is difficult to be induced.

In order to solve the above-described problem, an aspect of the present invention provides a moving image display unit that displays a moving image viewed by a user on a vehicle, a vibration detection unit that detects vibration received by the user, A vibration characteristic change determination unit that determines whether or not to change the vibration characteristic of the vehicle based on the display state of the moving image in the moving image display unit and the characteristic of the vibration detected in the vibration detection unit; A control signal generation unit configured to generate a control signal for changing the vibration characteristics of the vehicle when the result of the determination needs to be changed.

According to the present invention, it is possible to detect that the user is prone to motion sickness and to change the characteristics of the vehicle so that the motion sickness is not easily induced.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The mobile terminal 100, which is an embodiment of the mobile terminal device according to the present invention, is a “vehicle” in a situation in which a passenger on a vehicle easily induces motion sickness such as watching video content. One aspect of the present invention is to control the motion characteristics of the vehicle so as to suppress the induction of “drunk”. That is, according to the mobile terminal 100 according to the present embodiment, if the passenger is prone to motion sickness, the vibration characteristics of the vehicle are changed. If the motion sickness is not likely to occur, The effect of automatically changing to vibration characteristics giving priority to comfort can be achieved.

FIG. 1A is a diagram illustrating a usage mode of the mobile terminal 100 according to the first embodiment. In the present embodiment, a case where a user 1010 and a driver 1020 are on a vehicle 500 will be described as an example. The user 1010 is in the vehicle 500 while holding the mobile terminal 100. Although FIG. 1A illustrates a state where the user 1010 is sitting on the back seat of the driver 1020, the user 1010 may be sitting on the seat next to the driver 1020.

When the portable terminal 100 is brought into the vehicle 500, the mobile terminal 100 transitions to a state linked to the vehicle 500, and changes the vibration characteristics of the vehicle 500 so as to suppress the induction of motion sickness in the user 1010. It has a function to control.

The vehicle 500 is, for example, a general passenger car, and the vehicle illustrated in FIG. 1 is a four-seater sedan family car. The vehicle 500 is not limited to a passenger car, and may be a large vehicle on which a large number of people ride.

The situation in which motion sickness is likely to be induced in the user 1010 is a state in which the user 1010 is on the vehicle 500 while viewing the video content using the mobile terminal 100. In the following description, it is assumed that the user 1010 is watching TV broadcast or moving image content via the mobile terminal 100. In addition to the moving images, fine characters such as SNS and books may be displayed on the screen of the mobile terminal 100 viewed by the user 1010, and the user 1010 may stare at the screen of the mobile terminal 100.

FIG. 1B is a diagram for explaining a traveling state of the vehicle 500. As shown in FIG. 1B, when the vehicle 500 travels on an uneven road surface 600, the vehicle 500 vibrates accordingly. In general, the vehicle 500 includes a device for reducing vibration from the road surface 600. As a result, the vibration experienced by the user 1010 is usually relatively gentle. Note that the vibration in the vehicle 500 varies depending on the setting of a device that reduces vibration.

When the vehicle 500 is a general sedan / family car, vibration is reduced by using a relatively soft spring in order to improve the riding comfort. As a result, even if the road surface 600 is a bad road, the rough and fast vibration according to the roughness of the road surface 600 is changed to a slow vibration about once every 3 seconds, for example, and transmitted to the user 1010. The user 1010 can ride in a comfortable state without feeling fast vibrations or large vibrations. However, the slow vibration of about once every 3 seconds is a situation in which it is easy to induce motion sickness especially in the user 1010 who is staring at the screen of the mobile terminal 100.

Accordingly, the mobile terminal 100 has vibration characteristics that are unlikely to induce motion sickness when the user 1010 who has boarded the vehicle 500 views TV broadcasts or moving image content, or stares at fine characters such as an SNS or a book. A control signal for the vehicle 500 is transmitted as described above. The vehicle 500 changes the setting of the suspension device according to the control signal. Specifically, based on a message from the mobile terminal 100, the setting of a suspension device composed of a spring and a damper that supports the vehicle 500 is changed to reduce vibration that creates a situation that is likely to cause motion sickness. To change.

[Relationship between vibration and motion sickness]
Here, an example of vibration of the vehicle 500 whose operation characteristics are controlled by the mobile terminal 100 according to the present embodiment will be described. FIG. 2A is an example of a waveform of vibrations experienced by a user 1010 who is riding on a vehicle 500 traveling on a road surface 600 when the vehicle 500 travels. In FIG. 2A, the amplitude X _A represents the vertical vibration amplitude of the vehicle 500. In the vibration waveform shown in FIG. 2A, the period t _A is a vibration period determined by the spring coefficient of the suspension device provided in the vehicle 500 and the mass of the vehicle 500. FIG. 2A is an example of a vibration waveform in a state in which the ride comfort in the vehicle 500 is improved because the vibration is reduced by the suspension device of the vehicle 500. This period t _A is, for example, about once every 3 seconds. The frequency having the period t _A is called a resonance frequency, and the vibration amplitude at the resonance frequency is theoretically infinite regardless of the mass. Giving the user 1010 vibration that has a large influence on the body, for example, when the elevator vibrates with a large amplitude at a frequency of once every 3 seconds, as in, for example, the moment when the elevator is raised or lowered, or when riding on a ship. become.

FIG. 2B is an example of a waveform of vibration when predetermined control is performed on the suspension device of the vehicle 500. In order to control vibration, it is fundamental to set passive control (passive control). In the case of the vehicle 500, this is done by adjusting the coefficients of the spring and the damper. The period t _B indicates the period of vibration, which is determined by the spring coefficient and the vehicle mass.

The spring has a characteristic of generating a reaction force proportional to the length of extension and contraction, and the relationship between the length and the reaction force is called a spring coefficient. Here, by increasing the spring coefficient, that is, by using a hard spring, the vibration period can be reduced. For example, since the vibration (about 0.3 Hz) once every 3 seconds can be set to a high frequency of several Hz, the vibration frequency of the vehicle can be shifted from the vibration frequency causing motion sickness. However, when the spring coefficient is increased from the beginning, the movement of the vehicle 500 as a whole also reacts to the small irregularities on the road surface 600, resulting in a harsh ride comfort, resulting in a phenomenon of worsening the ride comfort. Become.

Amplitude attenuation X _B in the illustrated graph in Figure 2B is generated by the attenuation of the damper. As a result, the amplitude of vibration in the vehicle 500 decreases with time and eventually approaches zero. By increasing the vibration damping X _B, for example, 3 seconds without vibration to induce motion sickness continues indefinitely as once, it can be suppressed quickly. As a result, the influence of vibration on the user 1010 riding on the vehicle 500 can be suppressed.

[Functional block of portable terminal device]

The near field communication unit 11 executes processing for establishing communication with the vehicle 500 via the near field communication I / F 118. By the short-range communication unit 11, the mobile terminal 100 executes a transmission process for transmitting a control command to the vehicle 500 and a reception process for receiving information notified from the vehicle 500.

The vibration detection unit 12 detects vibration felt by the user 1010 holding the mobile terminal 100 based on the acceleration data of the mobile terminal 100 detected by the acceleration sensor 119.

The vibration analysis unit 13 analyzes a detection result including a period and an amplitude related to the vibration detected by the vibration detection unit 12. The vibration data analyzed by the vibration analysis unit 13 is passed to the vibration component extraction unit 14. The vibration component extraction unit 14 extracts vibration components that the user 1010 is experiencing from vibration data passed from an external environment such as the vehicle 500 based on vibration data passed from the vibration analysis unit 13. The vibration component extracted by the vibration component extraction unit 14 is passed to the control signal generation determination unit 21.

The control signal generation determination unit 21 determines whether it is necessary to generate a control signal for the vehicle 500 based on the vibration component passed from the vibration component extraction unit 14 and the user setting information stored in the user setting storage unit 20. A vibration characteristic change determination unit is configured. When it is determined that the control signal generation determination unit 21 generates a control signal for the vehicle 500, the control signal generation determination unit 21 generates a control signal based on the determination and notifies the vehicle 500 via the short-range communication unit 11.

When the control signal generation determination unit 21 generates a control signal for changing the operation characteristics of the vehicle 500, the notification information display unit 22 displays a notification screen on the LCD 112 to notify the user 1010 to that effect.

[Operation of mobile terminal device]
Next, a vehicle control method executed in the mobile terminal 100 will be described using the flowchart of FIG. The flowchart shown in FIG. 4 exemplifies the flow of processing in the vehicle control program that can be executed in the mobile terminal 100. First, the user 1010 operates the mobile terminal 100 and inputs an operation from the user via the user operation receiving unit 18. Here, it is assumed that the user 1010 has performed an operation for viewing video content (S401).

Subsequently, the mobile terminal 100 establishes a communication state with the vehicle 500 on which the user 1010 is boarded by the short-range communication unit 11 (S402). If the mobile terminal 100 cannot establish a communication state with the vehicle 500 (S403 / NO), the mobile terminal 100 is stored in the image data acquired through the image data acquisition unit 15 or the image data storage unit 16. The displayed image data is displayed on the LCD 112, and the user 1010 views the video content (S405).

After it is determined that the communication state between the mobile terminal 100 and the vehicle 500 has been established (S403 / YES), it is determined whether or not the vehicle 500 is traveling (S404). Even if the vibration detection unit 12 detects the vibration of the mobile terminal 100 in S404, if the vibration does not accompany the movement of the vehicle 500, that is, travel (S404 / NO), the video content is simply viewed and terminated. The display of the video content is continued (S407, S408 / NO). That is, if the vibration is not transmitted to the user 1010 who is on board the vehicle 500, it is not necessary to change the operation characteristics of the vehicle 500.

In S <b> 404, if the vibration analysis unit 13 analyzes the vibration detected by the vibration detection unit 12, and it is determined that the resulting vibration data is due to the movement of the vehicle 500 (S <b> 404 / YES), the portable terminal 100 determines that the vehicle 500. A control signal (command A) for changing the operation characteristics is generated and output (S406). The control signal generated in S406 is to change the vibration characteristics of the vehicle 500 so that the vibration of the vehicle 500 becomes fine. That is, the mobile terminal 100 changes the vibration characteristics of the vehicle 500 based on the display state of the moving image on the image data display unit 17 and the vibration data detected by the vibration detection unit 12 and analyzed by the vibration analysis unit 13. Control signal to be generated and output.

The transmission of the control command in S404 is continued while the vehicle 500 is traveling (S404 / YES) and the viewing of the video content is continued (S408 / NO, S404, S406, S407). When viewing of the video content is completed (S408 / YES), a control command (command B) for restoring the vibration characteristics of the vehicle 500 is transmitted to the vehicle 500 (S409).

According to the vehicle control method described above, the mobile terminal 100 determines whether or not it is a “condition in which motion sickness is likely to be induced” such as when the user 1010 views video content while the vehicle 500 is traveling. be able to. The mobile terminal 100 can automatically change the operation characteristics of the vehicle 500 to the “mode in which motion sickness is not easily induced”. That is, according to the mobile terminal 100 according to the present embodiment, when the risk of motion sickness is high, control is performed to change the vibration characteristic of the vehicle 500 to “a state where the risk of motion sickness is low”.

In the processing flow described with reference to FIG. 4, the short-range communication unit 11 used for establishing the communication path in S402 may use a standardized communication standard such as Bluetooth (registered trademark). In this case, the operation may be performed so that the communication between the portable terminal 100 and the vehicle 500 is automatically established when the ignition key of the vehicle 500 is turned on and the power supply system of the vehicle 500 starts operating.

In addition, after the viewing of the video content is finished (S408 / YES), the vehicle command B may not be transmitted, and the suspension setting of the vehicle 500 may be changed to the setting for measures against motion sickness.

[Example of suspension structure]
Next, the vehicle 500 that changes the operating characteristics in accordance with the command A and the command B transmitted from the mobile terminal 100 will be described. First, an embodiment of a suspension 510 that is a suspension device mounted on a vehicle 500 will be described with reference to FIGS. 5A and 5B.

FIG. 5A is a schematic diagram showing a configuration of a suspension 510 attached to each of a plurality of tires 540 included in the vehicle 500. FIG. As shown in FIG. 5A, the suspension 510 has a damper 513 and an upper end of a spring 512 fixed to the vehicle 500, and a suspension shaft 511 to which a tire 540 is attached moves up and down with respect to the vehicle body. Operates to deal with vibrations. In addition, the suspension shaft 511 is provided with an actuator 514 so that force can be applied to the suspension shaft 511 in the vertical direction similarly to the linear motor by the principle of an electromagnet. The force applied to the suspension shaft 511 can be electrically controlled, and as described above, it is possible to apply a force that changes the spring constant. That is, the suspension 510 is a device that can arbitrarily control the vibration of the vehicle 500.

FIG. 5B is a view of the suspension 510 shown in FIG. 5A viewed from the lateral direction. An axle acceleration sensor 519 for detecting the acceleration received by each tire 540 is installed at the end of the rotation shaft of the tire 540 so that vibration from the road surface 600 can be directly measured. In the damper 513, the inside of the cylinder 515 is filled with the damper oil 518, and a piston 516 fixed to the suspension shaft 511 is contained therein. When the suspension shaft 511 moves up and down, the damper oil 518 passes between the piston holes 517, so that a reaction force proportional to the vertical movement of the suspension shaft 511, that is, the vertical movement speed of the piston 516 is generated.

The basic setting of the damper 513 is set by the diameter of the piston hole 517 and the viscosity of the damper oil 518. Changing the damping force in the damper 513 (the reaction force generated with respect to the speed as a coefficient) while the vehicle 500 is traveling is realized by changing the diameter of the piston hole 517. The damping force of the damper 513 can be changed with a relatively simple structure as compared with the structure in which the spring constant required by the actuator 514 is changed.

[Vehicle structure and vibration control method]
Next, an embodiment of a vehicle control system for controlling the vehicle by linking the mobile terminal device and the vehicle according to the present invention will be described. FIG. 6A is a configuration diagram illustrating an outline of the vehicle control system 520 according to the present embodiment. As shown in FIG. 6A, the vehicle control system 520 receives an acceleration signal from the axle acceleration sensor 519 attached to the suspension 510 described in FIG. 5 and calculates an acceleration data as an ECU (electronic device). control unit) 523, ECU 521 for controlling the overall operation of vehicle 500, and communication I / F 522 for processing communication connection with portable terminal 100, as well as a vehicle body acceleration sensor for detecting the overall vibration of vehicle 500 524.

The vehicle control system 520 is a vehicle control device for controlling the vibration characteristics of the vehicle 500 based on both the acceleration detection signal from the axle acceleration sensor 519 and the acceleration detection signal from the vehicle body acceleration sensor 524. Arithmetic processing by an ECU 523 is executed. ECU 523 outputs a control signal based on the calculation result to actuator 514 included in suspension 510. As a result, the vehicle 500 is set to vibration characteristics that avoid vibrations that induce motion sickness.

FIG. 6B is an example of a circuit that generates a feedback signal for the suspension 510. The ECU 523 executes a process corresponding to the circuit, generates a feedback signal for the suspension 510, and controls an operation to be notified to the suspension 510. The circuit shown in FIG. 6B illustrates a configuration that generates a control signal to be sent to the actuator 514 of the suspension 510 based on the acceleration detection signal from the vehicle body acceleration sensor 524.

The acceleration signal detected by the vehicle body acceleration sensor 524 is integrated by the first integration circuit 525 and multiplied by a predetermined gain by the first gain circuit 527. This is added by the first adder 528 to calculate the speed. This speed is further integrated by the second integration circuit 526, and a predetermined gain is multiplied by the second gain circuit 529. This is added by the second adder 530 to calculate the displacement. As described above, the control signal is generated by adding the acceleration, the speed, and the displacement based on the acceleration detection signal from the vehicle body acceleration sensor 524 with the values multiplied by the set gains. By sending this control signal to the actuator 514 of the suspension 510, basic vibration control can be performed.

The vehicle control system 520 included in the vehicle 500 described above is an example of the simplest control system that uses only the vehicle 500 itself, that is, the vehicle body acceleration sensor 524 that detects vibration on the upper side of the suspension 510. Since the vehicle 500 is provided with the axle acceleration sensor 519 at the positions of the four tires, an integrated calculation process using the acceleration detection signals from the plurality of axle acceleration sensors 519 is performed, and the tires 540 again. An operation for changing the vibration characteristics of the vehicle 500 can also be performed by generating and transmitting a vibration control signal for the suspension 510.

That is, by calculating so as to integrate vibration information from a plurality of sensors provided in various places of the vehicle 500, a user 1010 who is in a certain position of the vehicle 500, such as a rear seat or a passenger seat, can The vibration to be received can be extracted.

[Relationship between vibration control and vibration]
Here, the difference in the vibration frequency depending on the presence or absence of vibration control in the vehicle 500 will be described with reference to the graph of FIG. FIG. 7 shows the vibration characteristics of the vehicle 500 with the horizontal axis representing frequency and the vertical axis representing amplitude. In FIG. 7, a characteristic A indicated by a solid line exemplifies a vibration characteristic of the vehicle 500 when no control is performed. Since the vehicle 500 is supported by a plurality of suspensions 510, a plurality of amplitude peaks occur. Particularly in the vicinity of the frequency f _A, there is a resonance frequency as described in Fig. Therefore, the amplitude X _{A at} the frequency f _A is a large amplitude.

If you set soften the spring to improve the riding comfort of the vehicle 500, the frequency _{f A} becomes approximately 0.3 Hz. In this case, the ride comfort of the vehicle 500 is good, but the user 1010 always receives a large vibration slowly. Therefore, the setting for improving the riding comfort of the vehicle 500 becomes a cause of motion sickness.

A characteristic B indicated by a one-dot chain line illustrates the vibration characteristic of the vehicle 500 when the vibration damping coefficient of the damper 513 is increased. Peak vibration frequency in this case is the frequency f _B. The frequency f _B is higher than the frequency f _A in the characteristic A. Further, the amplitude X _B when the vibration frequency of the characteristic B reaches a peak is smaller than the amplitude X _A in the characteristic A. The occurrence of motion sickness can be suppressed by shifting the peak frequency from a frequency at which motion sickness is likely to occur. However, since the characteristic B has a higher high frequency component than the characteristic A, the amplitude is also increased. For this reason, it becomes a harsh ride, and compared with the characteristic A, the ride feels worse.

A characteristic C indicated by a broken line exemplifies a vibration characteristic of the vehicle 500 when a control signal is transmitted to the actuator 514 and a spring constant is controlled using the circuit illustrated in FIG. 6B. As shown in FIG. 7, the characteristic C has a small amplitude as a whole and does not have a specific peak frequency. Therefore, the vibration of the vehicle 500 can be suppressed to a certain level regardless of the unevenness of the road surface 600. As a result, it is possible to obtain a comfortable vehicle vibration with no frequency sickness and a small amplitude.

As described above, the vehicle control system 520 according to the vehicle 500 controls the vehicle 500 so that the vibration characteristic becomes the characteristic C, so that even if the user 1010 views the video content while the vehicle 500 is moving, the vehicle The occurrence of sickness can be suppressed. The setting characteristics of the vibration characteristics of the three types of vehicles 500 illustrated in FIG. 7 can be controlled with a certain degree of freedom. Therefore, the actual occurrence of motion sickness can be suppressed by appropriately switching the vibration mode of the vehicle 500 in a situation where it is easy to induce motion sickness, such as staring at video content.

When the mobile terminal 100 displays a TV or a moving image while riding the vehicle 500, the mobile terminal 100 instructs the vehicle 500 to switch the vibration mode by transmitting a control signal for changing the vibration characteristics to the vehicle 500. Can do.

The vehicle 500 including the vehicle control system 520 according to the present embodiment includes an in-vehicle TV 550 as illustrated in FIG. In the embodiment described above, the vibration mode of the vehicle 500 is switched when video content such as a TV or a moving image is displayed on the mobile terminal 100 held by the user 1010. In this embodiment, when the vehicle-mounted TV 550 installed in advance in the vehicle 500 displays a TV or a moving image, the vibration mode of the vehicle 500 is switched.

When the video content or the like is displayed on the in-vehicle TV 550, the user 1010 determines that the image is staring, and the vehicle 500 switches to the vibration mode that suppresses motion sickness as described above. In this operation, the in-vehicle TV 550 mounted on the vehicle 500 transmits a message indicating that the user 1010 may cause motion sickness to the vehicle 500, and the vehicle receives the message to set the suspension device. To change. This is realized by combining both the function of the in-vehicle TV 550 and the function of the vehicle.

[Functional configuration of vehicle control system]
Next, another embodiment of the vehicle control system according to the present invention will be described. In this embodiment, in particular, the vibration detection function built in the portable terminal 100 held by the user 1010 and the vibration detection function of the vehicle 500 are linked to calculate the vibration component received by the user 1010 itself. Thus, it is characterized by determining whether or not the vibration is equivalent to the occurrence of motion sickness.

FIG. 9 is a diagram illustrating a functional configuration of the vehicle control system 520 that links the mobile terminal 100 and the vehicle 500. As shown in FIG. 9, in the mobile terminal 100, moving image content by television broadcasting or network broadcasting is received from the moving image receiving unit 904. The received moving image is stored in the moving image storage unit 903.

Here, even in the case of a live broadcast or a video that cannot be recorded, the moving image storage unit 903 functions as a buffer that temporarily stores in units of packets or frames. The stored moving image is displayed on the video display unit 902. From reception to storage and display of these moving images, the operation is performed according to an instruction from the user 1010 input from the user operation reception unit 901. When there is a moving image display instruction from the user 1010, the user operation reception unit 901 transmits information indicating that the operation has been performed toward the vehicle 500 using the terminal-side communication unit 905.

Note that the terminal-side communication unit 905 not only indicates that a moving image display instruction has been given, but also when the user 1010 gets on the vehicle 500 and the vehicle 500 departs, the user 1010 and the mobile terminal 100 enter the vehicle 500. It also has a function of transmitting information indicating that the user has boarded the vehicle 500 in advance.

Separately from these operations, the mobile terminal 100 includes a terminal vibration detection unit 908 including an acceleration sensor 119 and the like. The vibration detected here is converted into a frequency component as shown in FIG.

Next, the value is sent to the vibration component extraction unit 906. The vibration component extraction unit 906 receives, for example, a frequency component of the vibration of the vehicle 500 itself received from the vibration analysis unit 916 mounted on the vehicle 500. The vibration component extraction unit 906 uses both the vibration frequency component of the mobile terminal 100 and the frequency component of the vehicle 500 to extract the vibration component received by the user 1010 holding the mobile terminal 100, which is, for example, motion sickness. It is determined whether or not a frequency component that induces is included. Specifically, the vibration component extraction unit 906 extracts the vibration component received by the user 1010 by calculating the difference between the vibration frequency component of the mobile terminal 100 and the frequency component of the vehicle 500. It is determined whether or not the vibration component includes a frequency component that induces motion sickness, for example, a frequency component corresponding to 0.3 Hz.

Here, the vibration received by the mobile terminal 100 is, for example, the vibration resulting from adding the shaking component of the user 1010 to the mobile terminal 100 above the user 1010 in addition to the vibration component received by the user 1010 from the vehicle 500. It is. By performing this component extraction using components from the vehicle 500, the extracted shaking component of the user 1010 can be made into a database. As described above, when the shaking component of the user 1010 is made into a database, the calculation process assuming the vibration received by the user 1010 can be executed using the vibration received by the mobile terminal 100 in any situation.

The vehicle 500 analyzes the vibration of the vehicle 500 by the vehicle vibration detection unit 915 and the vibration analysis unit 916 similarly to the mobile terminal 100, and determines whether this induces motion sickness of the user 1010.

Here, the in-vehicle TV 550 illustrated in FIG. 8 is fixed to the vehicle 500, and whether or not the user 1010 is watching a moving image on the in-vehicle TV 550 by the in-vehicle TV moving image state detection unit 914, that is, the in-vehicle TV 550 Detects whether a switch is turned on and a moving image is displayed.

In addition, when the user 1010 gets on the vehicle 500 together with the mobile terminal 100 and receives an instruction to display a moving image from the user 1010 received by the vehicle-side communication unit 911, information information indicating that the operation has been performed, Together with the operation start information of the in-vehicle TV 550, the user terminal detection unit 912 is gathered.

The terminal operation status detection unit 913 uses these pieces of information to determine a situation where the user 1010 on the vehicle 500 is staring at the moving image using the mobile terminal 100 or the in-vehicle TV 550. In this case, the command A is notified to the suspension device control signal generation unit 917 so as to prevent motion sickness. The command A, which is a control signal generated by the suspension device control signal generation unit 917, is transmitted to the suspension control unit 910, which is a suspension device, for example, by changing the gain of each signal described in FIG. 6B. The suspension control unit 910 controls the vibration of the vehicle so as to obtain a vehicle vibration that does not cause motion sickness as shown in the graphs of FIG.

Further, the mobile terminal 100 according to the present embodiment includes a profile setting unit 918 and a profile storage unit 919. The profile setting unit 918 is a unit that inputs user profile information, which is personal information of the user 1010, via the profile setting screen configured by the LCD 112 and the touch panel 113 and sets the user profile information in the mobile terminal 100. As shown in FIG. 13, the profile setting screen 1300 can be set in advance as to whether or not the user 1010 who is the owner of the mobile terminal 100 is likely to get motion sickness as specific information to be self-reported. The profile information input in the profile setting unit 918 is stored in the profile storage unit 919.

The profile information of the owner of the mobile terminal 100 includes information indicating whether the owner is “prone to motion sickness” in addition to personal information such as name, phone number, e-mail address, and address. In editing personal information, information is appropriately set in the biometric information field 1310 of the profile setting screen 1300. As a result, information indicating that it is likely to cause motion sickness or does not cause motion sickness is set in advance.

When notifying the terminal-side communication unit 905 of the vibration component extracted in the portable terminal 100, when notifying the vehicle 500 via the biological information column 1310 related to the user 1010 stored in the profile storage unit 919 Information is also notified. If the user 1010 is a person who is not prone to motion sickness, the generation of the command A may be stopped even if the vibration component induces motion sickness.

In other words, in the mobile terminal 100 that is set to be “difficult to get motion sickness”, when the user 1010 performs an operation that induces motion sickness such as staring at a moving image when the user 1010 gets on the vehicle. Even if it exists, the operation | movement for making it the vibration characteristic which is hard to make motion sickness with respect to the vehicle 500 is not performed.

On the other hand, in the mobile terminal 100 that is set to “prone to motion sickness”, when the user 1010 gets on the vehicle 500 and communication with the vehicle 500 is established, the setting of the suspension control unit 910 is changed, Preventive action can also be taken to achieve vibration characteristics that are less likely to cause motion sickness.

Next, another embodiment of the portable terminal device according to the present invention will be described. As shown in FIG. 10, the mobile terminal 100 a according to the present embodiment is a wearable device that is worn by a user 1010. As shown in FIG. 10A, the portable terminal 100a is a wristwatch type that the user 1010 wears on his / her arm. When boarding the vehicle 500 with the mobile terminal 100a mounted, communication is established between the mobile terminal 100a and the vehicle 500.

Since the mobile terminal 100a is worn by the user 1010, the mobile terminal 100a has a biological information detection unit that collects information related to the physical condition related to the user 1010. As illustrated in FIG. 10B, the biological information detection unit included in the mobile terminal 100a includes, for example, a sweat detection unit 1001 that detects when the user 1010 is in a poor physical condition, a pulse detection unit 1002 that detects a change in the physical condition, and a user 1010. A body temperature detection unit 1003 for detecting body temperature. Moreover, the portable terminal 100a includes a physical condition analysis unit 1005 that analyzes information from the biological information detection unit. In addition, the mobile terminal 100a includes a vibration detection unit 1004 that detects vibrations received by the user 1010, and a car sickness detection unit 1006 that determines whether motion sickness has occurred based on the analysis result of physical condition.

The vehicle 500 includes a suspension device control signal generation unit 917 that transmits a command A to the suspension control unit 910 according to the determination result from the motion sickness detection unit 1006.

When the command A is transmitted from the mobile terminal 100a having the above function to the vehicle 500, the vibration characteristic of the suspension 510 provided in the vehicle 500 is changed to suppress the occurrence of motion sickness in the user 1010.

Also, each piece of information obtained by the mobile terminal 100a is held by the user 1010 and sent to the mobile terminal 100 that browses moving images. A vibration component received by the user 1010 can be extracted by using a vibration component from the portable terminal 100 a and a vibration component detected by the portable terminal 100 by the vibration component extraction unit 906 included in the portable terminal 100. As a result, similar to the embodiment described with reference to FIG. 9, it is possible to perform calculation processing for estimating the vibration received by the body of the user 1010.

The arithmetic processing for extracting the vibration received by the user 1010 using the vibration of the mobile terminal 100, the mobile terminal 100a, and the vehicle 500 of the user 1010 described in FIGS. 9 and 10 is an arithmetic processing in which a plurality of vibration information is integrated. It is feasible. For example, as in the vehicle 500 described with reference to FIG. 6, a user 1010 who is calculated by integrating vibration information from the vehicle body acceleration sensors 524 provided in various places of the vehicle 500 and gets on a specific position of the vehicle 500. The vibration to be received can be extracted.

Note that the mobile terminal 100a may have a function of directly reducing motion sickness of the user 1010 as shown in FIG. For example, the mobile terminal 100a includes a plurality of pins 1007 on the back surface.

When the mobile terminal 100a detects that motion sickness has occurred based on its own information or information analyzed by the physical condition analysis unit 1005, the pin 1007 protrudes at a predetermined timing or position. Further, the pin 1007 is also provided with a vibration mechanism, and appropriately stimulates the skin surface of the user 1010 to reduce motion sickness.

The method of performing some kind of treatment directly on the body of the user 1010 as in the mobile terminal 100a is not limited to applying stimulation by pressing the skin surface layer. For example, a device other than the mobile terminal 100a may be attached to various parts of the body, or a similar external device may be provided at a predetermined place on the clothes. In this case, a coping action when motion sickness occurs can be performed by pressing the skin surface layer, passing a weak current, or performing a necessary medical action. The portable terminal 100a can also issue an operation instruction to the external device.

Next, still another embodiment of the mobile terminal device according to the present invention will be described. The portable terminal 100b according to the present embodiment has a motion sickness warning display function for displaying information such as a warning screen 1200 shown in FIG. As described above, this embodiment is characterized in that the user 1010 is directly informed that the risk of motion sickness has increased, rather than the transmission of an instruction to the vehicle 500 that is on board.

FIG. 12A illustrates a state where a moving image is viewed on the mobile terminal 100b. When watching a moving image in the vehicle, a warning screen 1200 is displayed in the moving image display area of the mobile terminal 100a. The warning screen 1200 displays information notifying the user that there is a possibility that motion sickness may occur if viewing is continued as it is. In the moving image display area, in addition to moving images, still images mainly composed of characters such as books and SNS are also displayed. Even in this case, motion sickness is induced if the user keeps staring at the terminal for a predetermined time or longer. Therefore, even when a still image is displayed, when an operation such as periodically changing the page by touching the moving image display area is performed, a warning screen 1200 is displayed by estimating from the operation content. Also good.

12B, the mobile terminal 100b does not automatically instruct the vehicle 500 to change the vibration characteristics, but before sending the vibration characteristics change, the suspension 510 is displayed as in the warning screen 1200a. A button for transmitting the setting change command may be provided.
In any case, for example, when the owner of the mobile terminal 100b has a constitution that does not cause motion sickness, the information is set in advance as profile information, and communication between the mobile terminal 100b and the vehicle 500 is established. Thus, information for confirming the constitution related to motion sickness may be displayed.

Note that the vehicle 500 that has received the command A from the mobile terminal 100 can be set so that the owner of the vehicle 500 or the driver 1020 does not permit the suspension mode change at his / her own will. Further, the command A from the portable terminal 100 may be ignored if the vehicle 500 is set in advance in a suspension mode in which it is difficult for motion sickness. Further, a suspension setting menu that can be set by the driver 1020 may be provided, and an option of “sickness prevention” may be provided in the menu.

Next, still another embodiment of the vehicle control system according to the present invention will be described. As shown in FIG. 14, if the passenger 1010a holding the mobile terminal 100 is a bus 500a on which a plurality of passengers are boarding at the same time, control that takes into account the possibility of motion sickness in each passenger 1010a is required.

In FIG. 14A, a plurality of passengers 1010a are on a bus 500a driven by a driver 1020a, and some of them are staring at a moving image using the mobile terminal 100c. In this case, since there is a person who is at risk of motion sickness on the same bus 500a, it is desirable to set a suspension device that can cope with this. In addition, since there are a plurality of people who do not get motion sickness, it is basically desirable to set a suspension system that is comfortable to ride. A riding comfort control device 14001 is mounted on the bus 500a, and this device determines and controls how to finally change the setting of the suspension device.

FIG. 14B is a diagram illustrating an example of functions and operations of the ride comfort control device 14001. For example, the portable terminal 100c held by each of the plurality of passengers 1010a determines a condition such that each of them is on the bus 500a and is displaying a moving image. Each portable terminal 100c has a motion sickness warning unit 24 that determines that the risk of motion sickness is high based on the determination result.

When the motion sickness warning unit 24 of the mobile terminal 100c determines that the risk of motion sickness is high, the motion sickness presence / absence determination unit 14090 of the vehicle 500b transmits information to that effect. Each of the mobile terminals 100c indicates that when the passenger 1010a is on the bus 500a and has a high risk of motion sickness based on conditions such as displaying a moving image, the passenger is The presence determination unit 14090 is notified. In addition, the mobile terminal 100c has no reason to stop browsing of moving images such as incoming mails when the passenger 1010c stops viewing the video content in a relatively short time or before the video content ends. Regardless, the same notification is given when viewing is stopped.

In addition, the bus 500a has a passenger number management unit 14080. When the passenger 1010a gets on the bus 500a, the passenger number management unit 14080 grasps the number of passengers based on the number of communications established between the communication function of the bus 500a and the mobile terminal 100c. In addition, the number of passengers is ascertained using information obtained by using an electronic money function or the like provided in the mobile terminal 100c to pay the boarding fee when boarding. Passenger number management unit 14080 transmits the number of passengers 1010a to car sickness person presence / absence determination unit 14090 in advance.

In consideration of the total number of passengers 1010a, the number of people who are likely to have motion sickness, and the number of people who are thought to be actually causing motion sickness, the vehicle sickness person presence / absence determination unit 14090 sets the suspension device 14110. Determine whether to change. The car sickness person presence / absence determination unit 14090 transmits the determination result to the suspension device control signal generation unit 14100. The suspension device control signal generation unit 14100 generates a control signal that adjusts the characteristics of the suspension device 14110 uniquely or stepwise in a direction to prevent motion sickness based on the received determination result. The suspension device 14110 changes the setting based on the control signal, and makes the suspension device 14110 perform vibration control with the designated set value.

The car sickness person presence / absence determination unit 14090 sets an appropriate setting in the suspension device based on the ratio of the number of persons who are at risk of motion sickness to the total number of passengers 1010a and the number of persons who are considered to have actually caused motion sickness. A control signal to be generated is generated. More specifically, the weighted value is added to each of the number of people who are at risk of motion sickness and the number of people considered to have motion sickness, and the judgment value is determined based on a comparison with a predetermined threshold value. Generate. Based on this determination value, an instruction is given to generate a control signal for performing appropriate settings for the suspension device. By controlling as described above, the setting of the suspension device can be set so as to be well balanced for all the passengers, not the setting biased toward the specific passenger 1010a.

When the degree of motion sickness changes depending on the seat position as in the bus 500a, the exchange of seats with a person who does not cause motion sickness may be promoted according to the motion sickness situation and occurrence risk in each of the passengers 1010a. . As a result, the passenger who causes motion sickness can be moved to a seat that does not cause motion sickness as much as possible, so that overall motion sickness can also be suppressed. For example, what is necessary is just to display the message and seat figure which request a seat change on the portable terminal 100c which each of the passenger 1010a has, or TV provided in each seat of the passenger 1010a. As a result, it is possible to promptly change the seat and to suppress the induction of motion sickness.

Next, still another embodiment of the mobile terminal device according to the present invention will be described. As shown in FIG. 15, in the present embodiment, the motion sickness situation of the user 1010 is detected using the in-vehicle camera 15040 provided in the vehicle 500c, the camera 15050 provided in the mobile terminal 100d, and the mobile terminal 100e worn by the user 1010. To do. The mobile terminal 100e is exemplified as a wearable wristwatch.

The camera 15050 provided in the portable terminal 100d constitutes a camera unit that periodically acquires an image of the face of the user 1010. The mobile terminal 100d extracts the position of the eyes included in the acquired face image of the user 1010, and determines whether or not the blurring is greater than or equal to a predetermined relative positional relationship with the mobile terminal 100d.

As a result of this determination, when the relative position blur between the mobile terminal 100d and the user 1010 is large, it can be determined that the user 1010 is on the moving vehicle 500. In this case, the warning screen 1200 described with reference to FIG. 12 is displayed on the display means provided in the mobile terminal 100d to notify that there is a risk of motion sickness. Further, if communication between the vehicle 500 and the portable terminal 100d is established, a control signal is notified so that the setting of the suspension 510 provided in the vehicle 500 is set to the motion sickness prevention setting.

In addition, in the above-described blur determination using the mobile terminal 100d, it is possible to more effectively suppress motion sickness by determining whether or not the blur includes a lot of frequency components around 0.3 Hz. .

Note that regular monitoring of the face of the user 1010 may be performed using the in-vehicle camera 15040. In this case, it is possible to analyze the face image of the user 1010 acquired by the in-vehicle camera 15040, determine the amount of shake, and determine whether the vehicle 500 is moving.

In addition, even when the in-vehicle TV 15060 is playing a video, if it can be determined that the user 1010 is asleep, the possibility of inducing motion sickness is reduced. Therefore, the in-vehicle camera 15040 monitors the eyes of the user 1010. A state determination unit configured by calculation means mounted on the vehicle 500 based on the image acquired by the in-vehicle camera 15040 determines the awakening state of the user 1010. When it is determined that the user 1010 is sleeping, a control signal for changing the vibration characteristics is notified to the suspension 510 so that the ride comfort is emphasized. Further, the user's 1010 sleep is not disturbed by turning off the power of the in-vehicle TV 15060. As a result, the occurrence of motion sickness can be efficiently suppressed. An option may be provided such as turning off the video of the in-vehicle TV 15060 and playing only sound.

In addition, the physical condition of the user 1010 may be detected using the function of the mobile terminal 100e, and detection of the risk of motion sickness may be used in combination with the user's 1010 pulse or sweating state. In this case, operations such as changing the setting of the suspension 510 and displaying a motion sickness occurrence risk warning on the screens of the mobile terminal 100d and the in-vehicle TV 15060 may be executed. Further, if communication is established between the portable terminal 100d, the portable terminal 100e, and the vehicle 500, necessary commands can be transmitted as appropriate.
