Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the prior art, although it was possible to prevent drowsy driving by vibration, the entertainment value was insufficient.

[0005] Therefore, an object of the present invention is to provide a vehicle interior system capable of enhancing entertainment value.

Means for Solving the Problems

[0006] To solve the above problems, a vehicle interior system according to the present invention includes a travel distance acquisition unit that acquires the travel distance of a vehicle, a first electric device provided in an interior member, a display unit that displays a character, and a control unit. The control unit changes the operation of the first electric device and the display of the character based on the travel distance acquired from the travel distance acquisition unit.

[0007] According to this configuration, since the operation of the first electric device and the display of the character are changed according to the travel distance, the entertainment value can be enhanced.

[0008] The vehicle interior system further includes a second electric device that operates by being energized, and a first operation unit for operating the first electric device, and the control unit may be capable of selecting and executing first control and second control. The first control is control for setting the first electric device to a first operating state corresponding to the first operation command when a first operation command is acquired from the first operation unit. The second control is control for setting the first electric device to a second operating state not corresponding to the first operation command and / or operating the second electric device when a first operation command is acquired from the first operation unit. The control unit may change the probability of selecting the first control based on the travel distance acquired from the travel distance acquisition unit.

[0009] Further, when the travel distance acquired from the travel distance acquisition unit exceeds the threshold value, the control unit may increase the probability of selecting the first control as compared with the case where the travel distance acquired from the travel distance acquisition unit is equal to or less than the threshold value.

[0010] According to this configuration, since the probability of selecting the first control increases when the travel distance exceeds the threshold value, it is possible to suppress the irritation of a user who is fatigued by long-distance driving when the second control is executed.

[0011] Further, as the second control, the control unit selects and executes at least one process from a plurality of candidates including a first process for setting the first electric device to the second operating state and a second process for operating the second electric device. When the travel distance acquired from the travel distance acquisition unit is equal to or less than the threshold value, the number of candidates may be set to a first value, and when the travel distance acquired from the travel distance acquisition unit exceeds the threshold value, the number of candidates may be set to a second value smaller than the first value.

[0012] According to this configuration, when the travel distance exceeds the threshold value, the number of processes to be selected as the second control decreases. For example, when moving a character by an operation corresponding to the second control, the pattern in which the character makes an incorrect operation decreases, so that the user can feel that the character is growing.

[0013] Also, the character is an image imitating a living being, and when the travel distance acquired from the travel distance acquisition unit exceeds a threshold value, the control unit may display an image of a grown living being as the character, rather than when the travel distance acquired from the travel distance acquisition unit is equal to or less than the threshold value.

[0014] According to this configuration, when the travel distance exceeds the threshold value, a grown character is displayed, so that the entertainment value can be enhanced. Also, for example, when the probability of selecting the first control increases when the travel distance exceeds the threshold value, the user can recognize that the number of times of making an operation command error has decreased due to the growth of the character.

[0015] The first electric device is an air conditioner, and when the control unit acquires a command to raise the vehicle interior temperature as the first operation command and executes the second control, the control unit may set the air conditioner to the second operating state and lower the vehicle interior temperature.

[0016] Also, the first electric device is a device that moves at least a part of a movable part of a seat, and when the control unit acquires a command to move the movable part in a predetermined direction as the first operation command and executes the second control, the control unit may set the first electric device to the second operating state and move the movable part in a direction opposite to the predetermined direction.

[0017] According to this configuration, since the movable part is moved in a direction opposite to the operation command, the user can clearly know that an incorrect operation has been performed with respect to the operation command.

[0018] Also, at least one of the first electric device and the second electric device is a device that moves at least a part of a movable part of a seat, and in the second control, when the travel distance acquired from the travel distance acquisition unit exceeds the threshold value, the control unit may increase the amount of movement of the movable part as compared with the case where the travel distance acquired from the travel distance acquisition unit is equal to or less than the threshold value.

[0019] Further, a plurality of vibration devices as the second electric device may be provided, and the control unit may select a vibration device to be operated from among the plurality of vibration devices in the second control.

[0020] Furthermore, a collision detection unit provided in the vehicle may be further provided, and when the control unit predicts a collision of the vehicle based on information from the collision detection unit, the second control may not be executed.

[0021] According to this configuration, when there is a possibility of a collision of the vehicle, the second control is not executed, so that safety can be improved.

Effects of the Invention

[0022] According to the present invention, since the operation of the first electric device and the display of the character are changed according to the traveling distance, the entertainment property can be enhanced.

[0023] Further, by adopting a configuration in which the probability of selecting the first control increases when the traveling distance exceeds a threshold value, a user who is fatigued by long-distance driving can be suppressed from getting irritated by the execution of the second control.

[0024] Further, by adopting a configuration in which the number of processes to be selected as the second control decreases when the traveling distance exceeds a threshold value, for example, when moving a character with an operation corresponding to the second control, the pattern in which the character makes an incorrect operation decreases, so that the user can feel that the character is growing.

[0025] Further, by adopting a configuration in which a grown character is displayed when the traveling distance exceeds a threshold value, the entertainment property can be enhanced. For example, when the probability of selecting the first control increases when the traveling distance exceeds a threshold value, the user can recognize that the number of times of making an operation command error has decreased due to the growth of the character.

[0026] Further, by adopting a configuration in which the movable part is moved in a direction opposite to the operation command, the user can clearly know that an incorrect operation is being performed with respect to the operation command.

[0027] In addition, by adopting a configuration in which the second control is not executed when there is a possibility of a vehicle collision, safety can be improved.

Mode for Carrying Out the Invention

[0029] [First Embodiment] Hereinafter, a first embodiment of the vehicle interior system will be described with reference to the accompanying drawings. As shown in FIG. 1, the vehicle interior system 1 includes a seat 10 as an example of an interior member, a camera C as an example of a collision detection unit, a running distance acquisition unit 200, a monitor M as an example of a display unit, and a control unit 100. The seat 10, the camera C, and the monitor M are arranged at positions facing the inside of the vehicle, specifically, the passenger compartment. In the present embodiment, the seat 10 is a driver's seat or a passenger seat.

[0030] The seat 10 includes a seat cushion 11, a seat back 12, and a headrest 13. The seat cushion 11, the seat back 12, and the headrest 13 each constitute a seat body having a seating surface F. The seating surface F is a surface that contacts the user sitting on the seat 10 and supports the user.

[0031] The seat cushion 11, the seat back 12, and the headrest 13 each have a metal frame constituting a skeleton, a pad covering the frame, and a skin covering the pad. The pad is made of urethane foam or the like. The skin is made of synthetic leather, fabric, or the like.

[0032] The seat cushion 11 has a base portion 11A disposed at the left - right center and projecting portions 11B disposed on both outer sides of the base portion 11A. The base portion 11A has a seating surface F that contacts and supports the user's buttocks and thighs from below. The projecting portions 11B project toward the user from the seating surface F of the base portion 11A to support the sides of the user's thighs and buttocks.

[0033] Similarly, the seat back 12 also has a base portion 12A disposed at the left - right center and projecting portions 12B disposed on both outer sides of the base portion 12A. The base portion 12A has a seating surface F that contacts the user's back and supports the back from behind. The projecting portions 12B project toward the user from the seating surface F of the base portion 12A to support the sides of the user's upper body.

[0034] The seat 10 further includes an electric reclining mechanism 21 and an electric slide mechanism 30. The electric reclining mechanism 21 is an electric device that tilts the seat back 12. The electric reclining mechanism 21 includes a motor that operates when energized.

[0035] The electric slide mechanism 30 is an electric device that slides the seat 10 in the front - rear direction. Here, the seat 10 is supported movably in the front - rear direction on a slide rail (not shown). The electric slide mechanism 30 includes a motor that operates when energized.

[0036] The seat 10 further includes a reclining switch 61, a slide switch 62, and a mode - switching switch 63.

[0037] The reclining switch 61 is an operation unit for operating the electric reclining mechanism 21. The reclining switch 61 is, for example, tiltable in the front-rear direction. When the reclining switch 61 is tilted forward, it outputs a forward tilt command for tilting the seat back 12 forward to the control unit 100. When the reclining switch 61 is tilted rearward, it outputs a rearward tilt command for tilting the seat back 12 rearward to the control unit 100.

[0038] The slide switch 62 is an operation unit for operating the electric slide mechanism 30. The slide switch 62 is, for example, slidable in the front-rear direction. When the slide switch 62 is slid forward, it outputs a forward movement command for moving the seat 10 forward to the control unit 100. When the slide switch 62 is slid rearward, it outputs a backward movement command for moving the seat 10 backward to the control unit 100.

[0039] The mode changeover switch 63 is a switch for switching the mode of the control unit 100 between a first mode and a second mode. Here, the first mode is a mode in which second control described later can be executed. The second mode is a mode in which the second control is not executed. The mode changeover switch 63 is, for example, a push-button type switch. Each time the mode changeover switch 63 is pressed by the user, it alternately switches between an ON state and an OFF state. In the present embodiment, the mode is set to the second mode when the mode changeover switch 63 is in the OFF state, and the mode is set to the first mode when the mode changeover switch 63 is in the ON state.

[0040] The camera C is a camera that photographs the front of the vehicle. The camera C is provided, for example, on the ceiling of the vehicle. The image information photographed by the camera C is output to the control unit 100.

[0041] The travel distance acquisition unit 200 has a function of acquiring the travel distance of the vehicle. The travel distance acquisition unit 200 acquires the travel distance from, for example, an odometer. Note that the travel distance acquired by the travel distance acquisition unit 200 may be, for example, the travel distance from when the ignition switch for starting the vehicle is turned ON until now (that is, the travel distance per ride), or the travel distance from when the vehicle was new until now.

[0042] The monitor M has a screen M1 (see FIG. 2) for displaying an image. The image displayed on the monitor M can be changed by the control unit 100. The monitor M can be arranged on the dashboard so as to be located, for example, under the rearview mirror.

[0043] The control unit 100 is configured to include, for example, a CPU, a RAM, a ROM, an input / output circuit, etc. The control unit 100 may be provided on the seat 10 or on a member other than the seat 10.

[0044] The control unit 100 is connected to the monitor M, various switches (61 to 63), the electric reclining mechanism 21, the electric slide mechanism 30, the camera C, the travel distance acquisition unit 200, and the monitor M. As shown in FIG. 3(a), the control unit 100 has a function of displaying, on the screen M1 of the monitor M, a seat image G1 which is an image of the seat and a cat image G2 which is an image imitating a cat as an example of a character. The control unit 100 has a function of selecting and executing the first control and the second control.

[0045] The first control is a control for setting the first electric device to a first operating state corresponding to the first operation command when the first operation command is acquired from the first operation unit. In other words, the first control is a control for operating the electric device in an operating state as intended by the user.

[0046] Specifically, when the control unit 100 executes the first control based on a command from the reclining switch 61, if the command is a forward tilt command, the electric reclining mechanism 21 is actuated so that the seat back 12 tilts forward, and if the command is a rearward tilt command, the electric reclining mechanism 21 is actuated so that the seat back 12 tilts rearward. In this case, the reclining switch 61 corresponds to the first operation unit, and the electric reclining mechanism 21 corresponds to the first electric device.

[0047] Also, when the control unit 100 executes the first control based on a command from the slide switch 62, if the command is a forward movement command, the electric slide mechanism 30 is actuated so that the seat 10 moves forward, and if the command is a backward movement command, the electric slide mechanism 30 is actuated so that the seat 10 moves backward. In this case, the slide switch 62 corresponds to the first operation unit, and the electric slide mechanism 30 corresponds to the first electric device.

[0048] The second control is a control for making the first electric device enter a second operating state that does not correspond to the first operation command or for actuating the second electric device when a first operation command is obtained from the first operation unit. In other words, the second control is a control for actuating the electric device in an operating state contrary to the user's intention.

[0049] As the second control, the control unit 100 selects and executes at least one process from a plurality of candidates including a first process for making the first electric device enter the second operating state and a second process for actuating the second electric device.

[0050] Specifically, when the control unit 100 executes the first process based on a command from the reclining switch 61, if the command is a forward tilt command, the electric reclining mechanism 21 is operated so that the seat back 12 tilts backward, and if the command is a backward tilt command, the electric reclining mechanism 21 is operated so that the seat back 12 tilts forward. Further, when the control unit 100 executes the first process based on a command from the slide switch 62, if the command is a forward movement command, the electric slide mechanism 30 is operated so that the seat 10 moves backward, and if the command is a backward movement command, the electric slide mechanism 30 is operated so that the seat 10 moves forward. That is, in the first process, the control unit 100 controls the electric device so as to perform an operation opposite to the operation command.

[0051] Here, the seat back 12 and the seat 10 correspond to a movable part that is at least a part of the seat 10. When the control unit 100 obtains a command to move the movable part in a predetermined direction as the first operation command and executes the second control (first process), the first electric device is set to the second operating state, and the movable part is moved in a direction opposite to the predetermined direction.

[0052] When the control unit 100 executes the second process based on a command from the reclining switch 61, regardless of the content of the command, the electric slide mechanism 30, which is an electric device different from the electric reclining mechanism 21, is operated to move the seat 10 forward or backward. When the control unit 100 executes the second process based on a command from the slide switch 62, regardless of the content of the command, the electric reclining mechanism 21, which is an electric device different from the electric slide mechanism 30, is operated to tilt the seat back 12 forward or backward.

[0053] The control unit 100 has a function of changing the probability of selecting the first control based on the travel distance D acquired from the travel distance acquisition unit 200. Specifically, when the travel distance D acquired from the travel distance acquisition unit 200 exceeds the threshold value, the control unit 100 increases the probability of selecting the first control compared to when the travel distance D acquired from the travel distance acquisition unit 200 is equal to or less than the threshold value.

[0054] Specifically, based on the map shown in Fig. 4(a), the control unit 100 sets the probability of selecting the first control and the probability of selecting the second control. Note that the numerical values shown in this specification, such as those in Fig. 4 and Fig. 5, are examples and can be arbitrarily changed.

[0055] When the travel distance D is less than the first threshold TH1, the control unit 100 sets the probability of selecting the first control to 50% and the probability of selecting the second control to 50%.

[0056] When the travel distance D is greater than or equal to the first threshold TH1 and less than the second threshold TH2, the control unit 100 sets the probability of selecting the first control to 70% and the probability of selecting the second control to 30%. Here, the second threshold TH2 is greater than the first threshold TH1. When the travel distance D is greater than or equal to the second threshold TH2, the control unit 100 sets the probability of selecting the first control to 90% and the probability of selecting the second control to 10%.

[0057] The control unit 100 has a function of changing the number of a plurality of candidates selectable as the second control based on the travel distance D acquired from the travel distance acquisition unit 200. Specifically, when the travel distance D acquired from the travel distance acquisition unit 200 is less than or equal to the threshold value, the control unit 100 sets the number of candidates to a first value, and when the travel distance D acquired from the travel distance acquisition unit 200 exceeds the threshold value, the control unit 100 sets the number of candidates to a second value smaller than the first value.

[0058] Specifically, based on the map shown in Fig. 4(a), when the travel distance D is less than the first threshold TH1, the control unit 100 sets the probability of selecting the first process to 40% and the probability of selecting the second process to 10%. When the travel distance D is greater than or equal to the first threshold TH1 and less than the second threshold TH2, the control unit 100 sets the probability of selecting the first process to 30% and the probability of selecting the second process to 0%. When the travel distance D is greater than or equal to the second threshold TH2, the control unit 100 sets the probability of selecting the first process to 10% and the probability of selecting the second process to 0%.

[0059] The maps in FIGS. 4(b), 5(a), and 5(b) show the map in FIG. 4(a) in detail. The control unit 100 sets each probability based on the maps in FIGS. 4(b), 5(a), and 5(b).

[0060] FIG. 4(b) is a map that the control unit 100 refers to when the travel distance D is less than the first threshold TH1. The numerical values in the columns indicated by diagonal hatching in the figure are the probabilities (%) of selecting the first control, the numerical values in the columns indicated by dot hatching are the probabilities (%) of selecting the first process as the second control, and the numerical values in the columns without hatching are the probabilities (%) of selecting the second process as the second control.

[0061] When the travel distance D is less than the first threshold TH1, the candidates selectable as the second control for one operation command (for example, reclining forward) are one first process and two second processes. That is, when the travel distance D is less than the first threshold TH1, the number of multiple candidates selectable as the second control is three.

[0062] On the other hand, as shown in FIGS. 5(a) and 5(b), when the travel distance D is greater than or equal to the first threshold TH1, the probabilities of selecting both of the two second processes are set to 0%. Therefore, the candidates selectable as the second control for one operation command (for example, reclining forward) are only one first process. Therefore, when the travel distance D is greater than or equal to the first threshold TH1, the number of multiple candidates selectable as the second control is one.

[0063] As shown in FIGS. 4(b), 5(a), and 5(b), as the travel distance D increases, the control unit 100 gradually increases the probability of selecting the first control in the order of 50%, 70%, and 90%, and gradually decreases the probability of selecting the first process of the second control in the order of 40%, 30%, and 10%. Since the first control is to move the first electric device with an operation corresponding to an operation command, and the first process is to move the first electric device with an operation not corresponding to the operation command, the control unit 100 changes the operation of the first electric device based on the travel distance D acquired from the travel distance acquisition unit 200. That is, the control unit 100 changes the operation of the first electric device based on the travel distance D so that the first electric device is moved with the correct operation with a high probability as the travel distance D increases.

[0064] As shown in FIG. 2, the control unit 100 has a function of changing the display of the character based on the travel distance D acquired from the travel distance acquisition unit 200. Specifically, when the travel distance D acquired from the travel distance acquisition unit 200 exceeds the threshold value, the control unit 100 displays an image of a grown cat as the character rather than when the travel distance D acquired from the travel distance acquisition unit 200 is below the threshold value.

[0065] Specifically, when the travel distance D is less than the first threshold value TH1, the control unit 100 displays a baby cat on the screen M1 as shown in FIG. 2(a). When the travel distance D is equal to or greater than the first threshold value TH1 and less than the second threshold value TH2, the control unit 100 displays a child cat that has grown a little from the baby on the screen M1 as shown in FIG. 2(b). When the travel distance D is equal to or greater than the second threshold value TH2, the control unit 100 displays an adult cat that has grown from the child on the screen M1.

[0066] In addition, the control unit 100 has a function of predicting a collision of the vehicle based on the information from the camera C shown in FIG. 1. When the control unit 100 predicts a collision of the vehicle, it has a function of not executing the second control. For example, when the control unit 100 predicts a collision of the vehicle in the first mode, it switches the mode to the second mode to not execute the second control.

[0067] Next, the operation of the control unit 100 will be described in detail. The control unit 100 repeatedly executes the process shown in FIG. 6. In the process of FIG. 6, the control unit 100 first determines whether the mode change switch 63 is ON (S1). If it is determined in step S1 that the mode change switch 63 is not ON (No), the control unit 100 sets the mode to the second mode (S9) and ends this process.

[0068] If it is determined in step S1 that the mode change switch 63 is ON (Yes), the control unit 100 determines whether there is a possibility that the vehicle will collide based on the information from the camera C (S2). If it is determined in step S2 that there is a possibility of vehicle collision (Yes), the control unit 100 sets the mode to the second mode (S9) and ends this process.

[0069] If it is determined in step S2 that there is no possibility of vehicle collision (No), the control unit 100 sets the mode to the first mode (S3). After step S3, the control unit 100 displays one of the images in FIGS. 2(a) to (c) as the home screen on the screen M1 according to the travel distance D acquired from the travel distance acquisition unit 200 (S4).

[0070] After step S4, the control unit 100 determines whether there is an operation command (S5). If it is determined in step S5 that there is no operation command (No), the control unit 100 ends this process.

[0071] If it is determined in step S5 that there is an operation command (Yes), the control unit 100 sets the probabilities of selecting each process (the first control, the first process as the second control, and the second process as the second control) based on the operation command and the travel distance D (S6). Specifically, in step S6, the control unit 100 selects one of the maps shown in FIGS. 4(b), 5(a), and (b) based on the travel distance D, and sets each probability based on the selected map and the operation command.

[0072] After step S6, the control unit 100 randomly selects a process with each set probability (S7). After step S7, the control unit 100 displays an image corresponding to the selected process and the travel distance D on the screen M1 (S8), and ends this process. Specifically, for example, when the process of tilting the seat back 12 backward by the electric reclining mechanism 21 is selected in step S7, the control unit 100 displays a video of a cat tilting the seat back backward on the screen M1 as shown in Fig. 3(a), and as shown in Fig. 3(b), operates the electric reclining mechanism 21 to actually tilt the seat back 12 backward. Although not shown in the figure, when the process of tilting the seat back 12 forward, the process of moving the seat 10 forward, or the process of moving the seat 10 backward is selected, an image corresponding to the content of the process is also displayed, and the seat 10 moves with an operation corresponding to the content of the process.

[0073] The image in Fig. 3(a) is an image when the travel distance D is equal to or greater than the first threshold TH1 and less than the second threshold TH2, and shows an image when a child cat is set as the character. When the travel distance D is less than the first threshold TH1, the control unit 100 replaces the cat in the image of Fig. 3(a) with a baby cat and displays it. When the travel distance D is equal to or greater than the second threshold TH2, the control unit 100 replaces the cat in the image of Fig. 3(a) with an adult cat and displays it.

[0074] Next, a specific example of the operation of the control unit 100 will be described. In the following description, the map in Fig. 4(b) is also referred to as the "first map", the map in Fig. 5(a) is also referred to as the "second map", and the map in Fig. 5(b) is also referred to as the "third map".

[0075] When the mode is the first mode and the driving distance D is less than the first threshold TH1, the control unit 100 displays the baby cat as the home screen on the screen M1 as shown in Fig. 2(a). After that, when a forward tilt command is output from the reclining switch 61, the control unit 100 selects the first map in Fig. 4(b) and sets the probabilities of each process corresponding to the forward tilt command. Specifically, the control unit 100 sets the probability that the process of tilting the seat back 12 forward by the electric reclining mechanism 21 (first control) is selected to 50%, the probability that the process of tilting the seat back 12 backward by the electric reclining mechanism 21 (first process) is selected to 40%, the probability that the process of moving the seat 10 forward by the electric slide mechanism 30 (second process) is selected to 5%, and the probability that the process of moving the seat 10 backward by the electric slide mechanism 30 (second process) is selected to 5%.

[0076] After that, the control unit 100 randomly selects a process with each set probability. For example, when the control unit 100 selects the process of tilting the seat back 12 backward by the electric reclining mechanism 21 (first process), it displays the video shown in Fig. 3(a) on the screen M1 and tilts the seat back 12 backward by the electric reclining mechanism 21.

[0077] When the mode is the first mode and the driving distance D is greater than or equal to the first threshold TH1 and less than the second threshold TH2, the control unit 100 displays the child cat as the home screen on the screen M1 as shown in Fig. 2(b). After that, when a forward tilt command is output from the reclining switch 61, the control unit 100 selects the second map in Fig. 5(a) and sets the probabilities of each process corresponding to the forward tilt command. Specifically, the control unit 100 sets the probability that the process of tilting the seat back 12 forward by the electric reclining mechanism 21 (first control) is selected to 70%, the probability that the process of tilting the seat back 12 backward by the electric reclining mechanism 21 (first process) is selected to 30%, the probability that the process of moving the seat 10 forward by the electric slide mechanism 30 (second process) is selected to 0%, and the probability that the process of moving the seat 10 backward by the electric slide mechanism 30 (second process) is selected to 0%.

[0078] When the running distance D is equal to or greater than the first threshold value TH1 and less than the second threshold value TH2, the probability of selecting the first control is higher than when the running distance D is less than the first threshold value TH1, and the processes selected as the second control are limited to only the first process. Therefore, since the first control is selected with a higher probability when the cat on the screen M1 is a child than when it is a baby, the user can feel that the cat has become smarter and the entertainment value can be enhanced.

[0079] When the mode is the first mode and the running distance D is equal to or greater than the second threshold value TH2, the control unit 100 displays an adult cat on the screen M1 as the home screen as shown in FIG. 2(c). Thereafter, when a forward tilt command is output from the reclining switch 61, the control unit 100 selects the third map in FIG. 5(b) and sets the probabilities of the respective processes corresponding to the forward tilt command. Specifically, the control unit 100 sets the probability that the process of tilting the seat back 12 forward (first control) by the electric reclining mechanism 21 is selected to 90%, the probability that the process of tilting the seat back 12 backward (first process) by the electric reclining mechanism 21 is selected to 10%, the probability that the process of moving the seat 10 forward (second process) by the electric slide mechanism 30 is selected to 0%, and the probability that the process of moving the seat 10 backward (second process) by the electric slide mechanism 30 is selected to 0%.

[0080] When the running distance D is equal to or greater than the second threshold value TH2, the probability of selecting the first control is higher than when the running distance D is equal to or greater than the first threshold value TH1 and less than the second threshold value TH2. Therefore, since the first control is selected with a higher probability when the cat on the screen M1 is an adult than when it is a child, the user can feel that the cat has become smarter and the entertainment value can be enhanced.

[0081] As described above, according to the present embodiment, the following effects can be obtained. Since the operation of the first electric device and the display of the character are changed according to the running distance D, the entertainment value can be enhanced.

[0082] Since the probability of selecting the first control increases when the driving distance D exceeds the threshold value, a user fatigued by long-distance driving can be prevented from getting irritated by the execution of the second control.

[0083] When the driving distance D exceeds the threshold value, the number of processes to be selected as the second control decreases, reducing the pattern in which the cat on the screen M1 performs incorrect actions, so that the user can feel that the cat is growing.

[0084] When the driving distance D exceeds the threshold value, a grown cat is displayed on the screen M1, enhancing the entertainment value. Also, as the cat on the screen M1 grows, the user can recognize that the number of times of making operation command mistakes has decreased.

[0085] In the first process, since the movable part is moved in the direction opposite to the operation command, the user can clearly know that an incorrect action is being performed with respect to the operation command.

[0086] When there is a possibility of vehicle collision, the second control is not executed, so the safety can be improved.

[0087] [Second Embodiment] Next, a second embodiment of the present invention will be described in detail with appropriate reference to the drawings. Note that since this embodiment is obtained by changing a part of the structure of the vehicle interior system according to the first embodiment described above, the same reference numerals will be given to the same components as in the first embodiment, and the description thereof will be omitted.

[0088] As shown in FIG. 7, the vehicle interior system 201 according to the second embodiment further includes a plurality of vibration devices 23 and an air conditioner 300 in addition to the configuration of the first embodiment.

[0089] The vibration device 23 is an electric device that reciprocates only a part of the surface of the seat 10 by vibrating when energized. Four vibration devices 23 are provided on the seat cushion 11, and six are provided on the seat back 12.

[0090] Specifically, in the seat cushion 11, a pair of vibration devices 23 arranged side by side left and right are arranged so as to be arranged front and back. In the seat back 12, a pair of vibration devices 23 arranged side by side left and right are arranged so as to be arranged up and down. The vibration device 23 is embedded in a pad, for example.

[0091] The air conditioner 300 is an electric device that discharges heated air or cooled air into the vehicle interior from an air outlet 310 provided on a dashboard or the like.

[0092] The control unit 100 according to the second embodiment selects a process with reference to a first map, a second map, and a third map different from the first embodiment. Specifically, when the driving distance D is less than the first threshold value TH1, the control unit 100 refers to the first map shown in FIG. 8. In addition to the first map in FIG. 4(b), three second processes are newly added to the first map in FIG. 8.

[0093] The newly added second processes are the following three processes. 1. A process of operating the vibration device 23. 2. A process of sending out heated air from the air conditioner 300 to raise the temperature inside the vehicle. 3. A process of sending out cooled air from the air conditioner 300 to lower the temperature inside the vehicle.

[0094] In the first map, the probability of selecting the first control is set to 50%, the probability of selecting the first process is set to 25%, and the probability of selecting each of the five second processes is set to 5% respectively. Thus, in the second embodiment, when the driving distance D is less than the first threshold value TH1, the number of a plurality of candidates that can be selected as the second control is six. Further, in the second embodiment, when the driving distance D is less than the first threshold value TH1, the control unit 100 targets an electric device (air conditioner) provided on an interior member (dashboard) other than the seat 10 in addition to the plurality of electric devices provided on the seat 10 as the second control.

[0095] When the travel distance D is equal to or greater than the first threshold value TH1 and less than the second threshold value TH2, the control unit 100 refers to the second map shown in FIG. 9. In the second map, the probabilities of selecting two second processes for operating the air conditioner 300 are both set to 0%. As a result, when TH1 ≤ D < TH2, the number of multiple candidates that can be selected as the second control is four. Also, in the second embodiment, when the travel distance D satisfies TH1 ≤ D < TH2, the control unit 100 targets only the electric devices provided on the seat 10 for the second control.

[0096] When the travel distance D is equal to or greater than the second threshold value TH2, the control unit 100 refers to the third map shown in FIG. 10. In the third map, the first process and four of the five second processes, excluding the process of operating the vibration device 23, are each set to 0%. As a result, when the travel distance D is equal to or greater than the second threshold value TH2, the number of multiple candidates that can be selected as the second control is one. Also, in the second embodiment, when the travel distance D is equal to or greater than the second threshold value TH2, the control unit 100 targets only the vibration device 23 for the second control.

[0097] In this way, since the electric devices targeted for the second control gradually decrease, such as all electric devices, a plurality of electric devices provided on the seat 10, and only the vibration device 23, the user can feel that the cat is growing.

[0098] When the control unit 100 operates the vibration device 23 as the second control, for example, as shown in FIG. 11, a video of the cat running around on the seat can be displayed on the screen M1. In this case, when the travel distance D is less than the second threshold value TH2, the control unit 100 does not target the vibration device 23 for the second control, and when the travel distance D is equal to or greater than the second threshold value TH2, the control unit 100 can target the vibration device 23 for the second control.

[0099] Specifically, for example, the probability of selecting the process of operating the vibration device in the first map and the second map shown in FIGS. 8 and 9 is set to 0%, and the 5% allocated to the process of operating the vibration device may be redistributed to other processes. In this way, when the vibration device 23 is made the target of the second control only when the travel distance D is equal to or greater than the second threshold value TH2, the user who views the video shown in FIG. 11 can feel that the cat is irritated and running around due to long-distance running, and can experience that the actual travel distance is long.

[0100] Also, in this case, the control unit 100 may select the vibration device 23 to be operated from among the plurality of vibration devices 23 in the second control. Specifically, when the travel distance D is equal to or greater than the second threshold value TH2, the control unit 100 may operate the plurality of vibration devices 23 on the seat back 12 in order from top to bottom, and then operate the plurality of vibration devices 23 on the seat cushion 11 in order from back to front. According to this, in conjunction with the display that the cat is irritated and running around due to long-distance running, the seating surface of the seat 10 vibrates like a wave, so that the user can feel the irritation of the cat more.

[0101] As shown in FIGS. 12 and 13, in the second control, when the travel distance acquired from the travel distance acquisition unit 200 exceeds the threshold value, the control unit 100 may increase the operation amount of the movable part more than when the travel distance acquired from the travel distance acquisition unit 200 is equal to or less than the threshold value. Here, the movable part in the form shown in FIGS. 12 and 13 is a part of the skin of the seat 10 that is moved by the vibration device 23.

[0102] For example, when the control unit 100 executes the second control to operate the vibration device 23 when the travel distance D is less than the first threshold value TH1, as shown in FIGS. 12(a) and (b), a baby cat is displayed as a character, and the vibration device 23 is vibrated with a predetermined first intensity.

[0103] When the control unit 100 executes the second control to activate the vibration device 23 when the travel distance D is equal to or greater than the second threshold value TH2, as shown in FIGS. 13(a) and 13(b), it displays an adult cat as a character and vibrates the vibration device 23 at a second intensity greater than the first intensity.

[0104] Note that, as the vibration device whose vibration intensity can be changed, for example, a type of vibration device that changes the vibration frequency and amplitude to change the vibration intensity can be adopted. Alternatively, instead of the vibration intensity, the vibration pattern may be changed according to the travel distance.

[0105] As shown in FIG. 14, the control unit 100 may execute the first control or the second control based on an operation command from an operation unit for operating the air conditioner 300. That is, the control unit 100 may execute the first control or the second control based on an operation command from an operation unit for operating an electric device provided in an interior member other than the seat 10.

[0106] Specifically, when the control unit 100 obtains a command to raise the vehicle interior temperature as the first operation command and executes the second control, it may set the air conditioner 300 to the second operating state to lower the vehicle interior temperature. Further, when the control unit 100 obtains a command to lower the vehicle interior temperature as the first operation command and executes the second control, it may set the air conditioner 300 to the second operating state to raise the vehicle interior temperature.

[0107] The electric device to be activated in the second control is not limited to one, and may be a plurality. For example, in the second control, the control unit may set the first electric device to the second operating state and activate the second electric device.

[0109] When the travel distance exceeds the threshold value, the character may perform an action display in accordance with the music played by the in-vehicle audio device for the occupant, and the vibration device may operate in accordance with the sound.

[0110] When the control unit predicts a vehicle collision, it may execute a collision prediction notification process to notify the user of the possibility of the vehicle collision.
