  However, in Patent Document 1, since information is presented to the driver only by vibration, there is a lack of affinity and there is room for improvement.

  The present invention has been made in consideration of the above-described facts, and an object thereof is to provide an information presentation apparatus that has high affinity and is capable of intuitive information presentation.

  In order to achieve the above object, an invention according to claim 1 is directed to armrests provided on at least one of left and right sides of a vehicle seat along a vehicle front-rear direction, and a stimulus including vibration and temperature change is given to an occupant. In the case where the situation is detected in front of the vehicle by the detection unit that detects the situation around the vehicle that needs to alert the occupant when the armrest is provided on either of the left and right sides. When the stimulus moves from the vehicle front side to the rear side of the armrest and the situation is detected behind the vehicle by the detection unit, the stimulus moves from the vehicle rear side to the front side of the armrest, respectively. A placement detector that controls the plurality of applying portions and detects placement of the arm on the armrest when the armrest is provided on both the left and right sides. Therefore, when it is detected that the occupant's arm is placed on each of the armrests, when the situation is detected on the right front side of the vehicle by the detection unit, from the front side of the right armrest to the rear side. When the stimulus moves and the detection unit detects the situation in the front left direction of the vehicle, the stimulus moves from the front side to the rear side of the left armrest, and the detection unit causes the situation to move to the right rear side of the vehicle. Is detected, the stimulus moves from the rear side of the right armrest to the front side of the vehicle, and when the detection unit detects the situation on the left rear side of the vehicle, the left side of the armrest moves from the rear side of the vehicle. Each of the plurality of applying units is controlled so that the stimulus moves to the front side, and the occupant's arm is placed on one of the armrests by the placement detection unit. When the situation is detected in front of the vehicle by the detection unit, the stimulus moves from the vehicle front side to the rear side of the left and right armrests, and the detection unit causes the situation to be behind the vehicle. And a control unit that controls the plurality of applying units so that the stimulus moves from the rear side to the front side of the left and right armrests when the left and right armrests are detected.

  According to the first aspect of the present invention, the plurality of applying portions are arranged along the vehicle front-rear direction on the armrest provided on at least one of the left and right sides of the vehicle seat. Each imparting unit imparts a stimulus including vibration and a temperature difference to the occupant.

  When the armrest is provided on either the left or right side, the control unit detects from the vehicle front side of the armrest when the situation is detected in front of the vehicle by the detection unit that detects the situation around the vehicle that needs to alert the occupant. When the stimulus moves to the rear side and the situation is detected behind the vehicle by the detection unit, each of the plurality of applying units is controlled so that the stimulus moves from the rear side of the armrest to the front side of the vehicle.

  In addition, when armrests are provided on both the left and right sides, detection is performed when the placement detection unit that detects the placement of the arm on the armrest detects that the arm of the occupant is placed on each armrest. When the situation is detected right front of the vehicle by the unit, the stimulus moves from the front side of the right armrest to the rear side, and when the situation is detected left front of the vehicle by the detection unit, the front side of the left armrest From the rear side of the right armrest to the front side, and the detection unit detects the situation on the left rear side of the vehicle. In this case, the plurality of applying units are controlled so that the stimulus moves from the vehicle rear side to the front side of the left armrest.

  On the other hand, when it is detected that the occupant's arm is placed on one of the armrests by the placement detection unit, when the situation is detected in front of the vehicle by the detection unit, both the left and right armrests are When the stimulus moves to the side and the situation is detected behind the vehicle by the detection unit, the plurality of applying units are controlled so that the stimulus moves from the vehicle rear side to the front side of both the left and right armrests.

  That is, a control part presents the information containing a direction by controlling a some provision part based on the detection result of a detection part, and providing the passenger | crew containing a vibration and a temperature difference to a passenger | crew.

  Thus, by presenting information to the occupant using not only vibration but also a temperature difference, it is possible to present information with higher affinity than when information is presented only by vibration. Moreover, since a some provision part is controlled so that a vibration and temperature difference move according to the direction which requires alerting, intuitive information presentation becomes possible.

  As described above, according to the present invention, there is an effect that it is possible to provide an information presentation apparatus with high affinity and capable of intuitive information presentation.

It is a perspective view showing the outline of the vehicular seat provided with the armrest provided with the information presentation device concerning the embodiment of the present invention. It is an enlarged view of an armrest part provided with an information presentation device concerning this embodiment. It is a block diagram which shows the structure of the information presentation apparatus which concerns on this embodiment. It is a flowchart which shows an example of the flow of the process performed with the information presentation apparatus which concerns on this embodiment.

  Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view illustrating an outline of a vehicle seat including an armrest provided with an information presentation device according to the present embodiment. FIG. 2 is an enlarged view of an armrest portion provided with the information presentation device according to the present embodiment.

  As shown in FIG. 1, the vehicle seat 12 includes a seat cushion 12A and a seat back 12B, and armrests (right armrest 14R and left armrest 14L) 14 are provided on both left and right sides of the seatback 12B. .

  Moreover, as shown in FIG. 2, the armrest 14 provided in the vehicle seat 12 is provided with a plurality of stimulus applying sections 16 as applying sections. FIG. 2A shows an example of an armrest 14 provided with five stimulus applying sections 16, and FIG. 2B shows an example of an armrest 14 provided with two stimulus applying sections 16.

  The stimulus applying unit 16 presents predetermined information by applying a stimulus including vibration and temperature change to the occupant. For example, by providing a vibration element and a thermal element, predetermined information is presented by applying vibration and temperature change to the occupant.

  In the present embodiment, the plurality of stimulus imparting units 16 present a situation requiring attention and its direction as predetermined information.

  For example, when there is an approaching vehicle from the right rear side of the vehicle, the stimulus applying unit 16 is sequentially driven from the stimulus applying unit 16 on the rear side of the right armrest 14R toward the stimulus applying unit 16 on the front side of the vehicle, and vibration and temperature A change (warm or cold) is applied to the right arm of the passenger. When there is an approaching vehicle from the left rear side of the vehicle, the stimulus applying unit 16 is driven in order from the stimulus applying unit 16 on the rear side of the left armrest 14L toward the stimulus applying unit 16 on the front side of the vehicle, and vibration and temperature A change (warm or cold) is applied to the left arm of the passenger. When there is an approaching vehicle from the front right side of the vehicle, the stimulus applying unit 16 is driven in order from the stimulus applying unit 16 on the front side of the right armrest 14R toward the stimulus applying unit 16 on the rear side of the vehicle, so that vibration and temperature are increased. A change (warm or cold) is applied to the right arm of the passenger. When there is an approaching vehicle from the left front of the vehicle, the stimulus applying unit 16 is driven in order from the stimulus applying unit 16 on the front side of the left armrest 14L toward the stimulus applying unit 16 on the rear side of the vehicle, and vibration and temperature A change (warm or cold) is applied to the left arm of the passenger. As a result, it is possible to present to the occupant the presence and direction of an approaching vehicle as a situation requiring attention.

  In the example of FIG. 2A, by driving each stimulus applying unit 16 in order, the stimulus applied to the occupant can move and alert the occupant including the directionality. On the other hand, in the case of the example shown in FIG. 2B, for example, by using the phantom sensation effect, it is possible to transmit the stimulus by the stimulus applying unit 16 including the direction to the occupant's arm. For example, by changing the intensity ratio of the stimulations by the two stimulation applying units 16 gradually and controlling the stimulation to increase from the front side to the rear side or from the rear side to the front side, the two stimulation applying units 16 The direction of the stimulus movement can be expressed. Specifically, when a Peltier element is used as the stimulus applying unit 16, it is possible to express a change in temperature change (movement of warm feeling or movement of cool feeling) between the two stimulus applying units 16.

  Next, the configuration of the information presentation device 10 according to the present embodiment will be described in detail. FIG. 3 is a block diagram illustrating a configuration of the information presentation apparatus 10 according to the present embodiment.

  The information presentation apparatus 10 includes an ECU (electronic control unit) 20 that controls the driving of the stimulus applying unit 16 as a control unit. The control unit ECU 20 includes a computer in which a CPU 20A, a ROM 20B, a RAM 20C, and an I / O (input / output interface) 20D are connected to a bus 20E.

  The ROM 20B stores a program for controlling the drive of the stimulus applying unit 16, and the drive of the stimulus applying unit 16 is controlled by developing the program stored in the ROM 20B on the RAM 20C and executing it by the CPU 20A. The

  Connected to the I / O 20D are a vehicle periphery monitoring device 22 as a detection unit, a drive driver 26 for driving the plurality of stimulus applying units 16, and an arm placement detection sensor 24 as a placement detection unit. In FIG. 3, the stimulus applying unit 16 is simplified to show only two without distinguishing the left and right armrests 14, but the ECU 20 distinguishes the stimulus applying unit 16 provided in each of the left and right armrests 14. It can be driven.

  The vehicle periphery monitoring device 22 monitors the periphery of the vehicle and detects obstacles and vehicles. For example, the vehicle periphery monitoring device 22 may apply a camera that captures the periphery of the vehicle and detect a situation around the vehicle such as an obstacle or an approaching vehicle from the captured image. Alternatively, the situation around the vehicle such as an obstacle or approaching vehicle may be detected using an ultrasonic radar or the like, or the situation around the vehicle may be detected together.

  The drive driver 26 transmits the vibration and temperature difference to the occupant's arm by driving the stimulus applying unit 16 corresponding to the instruction from the CPU 20A.

  Although only one arm placement detection sensor 24 is shown in FIG. 3, the arm placement detection sensor 24 is provided corresponding to each of the right armrest 14R and the left armrest 14L, detects the placement of the arm on each armrest 14, The detection result is output to the ECU 20. Thereby, the ECU 20 can detect whether or not the arm is placed on the armrest 14.

  Subsequently, the operation of the information presentation apparatus 10 according to the present embodiment configured as described above will be described. FIG. 4 is a flowchart illustrating an example of the flow of processing performed by the information presentation apparatus 10 according to the present embodiment. Note that the processing in FIG. 4 starts when the CPU 20A executes a program stored in the ROM 20B when an ignition switch (not shown) is turned on.

  In step 100, the ECU 20 acquires a vehicle periphery monitoring result by the vehicle periphery monitoring device 22, and the process proceeds to step 102. The ECU 20 acquires, for example, a result of photographing around the vehicle and a monitoring result such as an ultrasonic radar.

  In step 102, the ECU 20 determines whether it is necessary to alert the passenger. This determination is made based on the vehicle periphery monitoring result acquired in step 100. For example, it is determined whether an approaching vehicle or an obstacle is detected by monitoring a captured image or ultrasonic radar. If the determination is affirmative, the process proceeds to step 104. If the determination is negative, the process returns, and the process of step 100 is resumed or other processes are performed.

  In step 104, the ECU 20 determines whether both arms are on the armrest 14. In this determination, the ECU 20 determines whether arm placement is detected by the arm placement detection sensor 24 of each of the left and right armrests 14. If the determination is affirmative, the process proceeds to step 106, and if the determination is negative, the process proceeds to step 108.

  In step 106, the stimulus applying unit 16 of the armrest requiring attention is driven to return a series of processing, and the processing in step 100 is resumed or other processing is performed. For example, when an approaching vehicle or the like is detected from the right rear by the vehicle periphery monitoring device 22, the stimulus applying unit 16 is sequentially moved from the stimulus applying unit 16 on the right armrest 14R toward the stimulus applying unit 16 on the vehicle front side. Drive to apply vibration and temperature change (warm or cool) to the occupant's right arm. When the vehicle periphery monitoring device 22 detects an approaching vehicle or the like from the left rear of the vehicle, the stimulus applying unit sequentially from the stimulus applying unit 16 on the left armrest 14L toward the stimulus applying unit 16 on the vehicle front side. 16 is driven to apply vibration and temperature change (warm or cool) to the left arm of the passenger. When the vehicle periphery monitoring device 22 detects an approaching vehicle or the like from the right front of the vehicle, the stimulus applying unit sequentially from the stimulus applying unit 16 on the front side of the right armrest 14R toward the stimulus applying unit 16 on the rear side of the vehicle. 16 is driven to apply vibration and temperature change (warm or cool) to the right arm of the occupant. When the vehicle periphery monitoring device 22 detects an approaching vehicle or the like from the front left side of the vehicle, the stimulation applying unit sequentially from the stimulation applying unit 16 on the left armrest 14L toward the stimulation applying unit 16 on the vehicle rear side. 16 is driven to apply vibration and temperature change (warm or cool) to the occupant's left arm, so that the presence of the approaching vehicle including the direction of the approaching vehicle can be presented to the occupant.

  On the other hand, in step 108, the ECU 20 determines whether one arm is placed on the armrest 14. If the determination is affirmative, the process proceeds to step 110. If the determination is negative, the process returns and the process of step 100 is resumed or other processes are performed. In this embodiment, when the arm is not placed on the left and right armrests 14, the process is returned as it is, but the present invention is not limited to this. For example, an indication that the arm is placed on the armrest 14 may be displayed on a display device or the like (not shown), or an indication to alert the contents detected by the vehicle periphery monitoring device 22 may be displayed. .

  In step 110, the ECU 20 drives the stimulus applying portions 16 of the armrests 14R and 14L on both sides to return a series of processes, and restarts the process of step 100 or performs other processes. For example, when there is a vehicle approaching from the front such as the right front of the vehicle, and no arm is placed on one armrest 14, the stimulation is applied from the vehicle front side to the rear side of the stimulation applying unit 16 of both armrests 14R and 14L. The stimulus imparting unit 16 is sequentially driven toward the unit 16. When there is a vehicle approaching from the rear of the vehicle and no arm is placed on one armrest 14, the stimulus applying unit 16 from the rear side of the vehicle to the stimulus applying unit 16 of both armrests 14R and 14L. The stimulus imparting unit 16 is driven in order toward the. Accordingly, the armrest 14 on which the arm is placed is operated in the same manner, and vibration and temperature change (warm or cold) are applied to the arm placed on the armrest 14 of the occupant, thereby allowing the occupant to You can call attention. In the present embodiment, the stimulus applying portions 16 of the armrests 14R and 14L on both sides are driven, but only the stimulus applying portion 16 of the armrest 14 on which the arm is placed may be driven. .

  Thus, since the information presentation apparatus 10 according to the present embodiment presents information to the occupant using not only vibration but also a temperature difference, information presentation with higher affinity than when information is presented only by vibration is provided. It becomes possible. In addition, since the driving of the plurality of stimulus applying units is controlled so that the vibration and the temperature difference are moved according to a direction that requires attention, intuitive information presentation is possible.

  In addition, since the information presentation apparatus 10 according to the present embodiment transmits information by the stimulus imparting unit 16 provided on the armrest 14, the information presentation means that is particularly effective in the automatic driving technique that increases the chance of releasing the hand from the steering wheel. As expected.

  In the above embodiment, the temperature difference applied to the occupant by driving the stimulus applying unit 16 may be warm or cold. Moreover, you may make it give a passenger | crew separately a warm feeling and a cold feeling according to the information to show. For example, in the case of danger prediction such as the approach of a vehicle or obstacle, control is given so that a sensation is given to the occupant, and in the case of other information (for example, a suggestion of convenient functions), a sensation is given to the occupant May be.

  In the above embodiment, the example in which the armrests 14 are provided on both the left and right sides of the vehicle seat has been described. However, only one of the armrests 14 may be provided. In this case, the arm placement detection sensor 24 can be omitted because the control may be performed regardless of whether or not the arm is placed on the armrest 14.

  Further, the present invention is not limited to the above, and it is needless to say that various modifications can be made without departing from the gist of the present invention.
