When the pedal section 110 is operated, the pedal arm 114 is rocked and abuts on the elastic body 140, thus applying a load corresponding to operation force to the elastic body 140. The load is transferred to the load cell 160 over the elastic body 140 and a first plate section 131 for supporting it and is detected as a load. The game device 10 controls the movement of a game object on the basis of a load detected by the load cell 160.SELECTED DRAWING: Figure 4

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, since the technology of Patent Document 1 detects the depression amount of the pedal as a change in the pedal swing angle, it has been difficult to detect a small brake operation. That is, since it appears only slightly as a change in the swing angle, it has been difficult to surely detect a small brake operation and reflect it in the game play.

[0006] In addition, the brake pedal is a component in a game device for a car racing game that is subject to a large force and has a high operation frequency, so it tends to malfunction more easily than other components. From the perspective of the game device operator, it is desirable that component replacement during a malfunction is easy and that the cost required for component replacement is low.

[0007] Note that such problems are not limited to game devices for car racing games, but are the same problems regardless of the game genre for any game device having a pedal operation input unit.

[0008] The problem to be solved by the present invention is to provide a technology for a game device that can detect a small pedal operation.

Means for Solving the Problem

[0009] A first invention for solving the above-described problem is a game device including a pedal unit, a load cell, an elastic body installed between the pedal unit and the load cell, and a control unit that determines a parameter value used when controlling the movement of a game object based on a detection signal of the load cell and performs control of the movement of the game object.

[0010] According to the first invention, the game device can create a comfortable pedal feel with the elastic body, detect the operation load applied to the pedal unit by the user with high resolution using the load cell, and use it for controlling the movement of the game object. Therefore, a game device that can reliably detect a small pedal operation can be realized.

[0011] A second invention is a game device including, in the above-described game device, a support tool that supports the elastic body and the load cell in a predetermined positional relationship.

[0012] According to the second invention, the elastic body and the load cell can be held in a predetermined positional relationship. Therefore, the detection resolution by the load cell can be stably utilized.

[0013] The third invention is a game device in which, in the above-described game device, the support member has a first plate portion that supports the elastic body on an upper surface, a second plate portion that supports the load cell on an upper surface, and a hinge that connects the first plate portion and the second plate portion.

[0014] According to the third invention, the support member can be realized at low cost with a simple configuration.

[0015] The fourth invention is a game device in which, in the above-described game device, the pedal portion has a pedal plate and a pedal arm, and the support member is installed below the pedal arm.

[0016] The fifth invention is a game device in which, in the above-described game device, the game device further includes a swing shaft that swingably supports the pedal portion.

[0017] The fourth or fifth invention can preferably realize a game device using a so-called suspended pedal. According to the fourth or fifth invention, since the operating force (stepping force) applied by the user to operate the pedal portion can be directly transmitted to the load cell without changing the direction of the force action, it can be used without impairing the high detection resolution of the load cell.

[0018] The sixth invention is a game device in which, in the above-described game device, the pedal arm has a fitting for contacting the elastic body on a lower surface.

[0019] According to the sixth invention, regardless of the shape of the pedal arm, the contact area with the elastic body can be appropriately ensured by the fitting.

[0020] The seventh invention is a game device in which, in the above-described game device, the elastic body has a chamfered portion at a corner that contacts the pedal arm in an upper portion.

[0021] According to the seventh invention, the chamfered portion secures a surface that receives the deviation of the contact point due to the depression of the pedal portion, and can avoid stress concentration due to the load applied to the elastic body. Therefore, the shearing action on the corner portion can be reduced to suppress the load, and the durability of the elastic body can be improved compared to the case where the chamfered portion is not provided.

[0022] According to the eighth invention, in the above game device, the support member has a mounting portion that can be removed from the housing while supporting the elastic body and the load cell.

[0023] According to the eighth invention, when it becomes necessary to replace the elastic body or the load cell, since the entire support member can be replaced, the labor and cost of replacement can be reduced, and the time required for maintenance can also be shortened.

[0024] According to the ninth invention, in the above game device, there is a pedal support mechanism having a spring that applies a biasing force in a direction opposite to the operating force applied to the pedal portion, and the pedal portion is supported at a position where play intervenes between the non-operating state where the stress corresponding to the operating force does not act on the elastic body and the state where the stress starts to act from the non-operating state.

[0025] According to the ninth invention, the so-called "brake play" in an actual vehicle can be reproduced.

[0026] According to the tenth invention, in the above game device, the control unit has a calibration control unit that performs calibration based on the detection signal in the non-operating state where the stress corresponding to the operating force applied to the pedal portion does not act on the elastic body.

[0027] According to the tenth invention, the zero point of the detection signal of the load cell can be appropriately corrected to realize accurate control related to pedal operation.

Mode for Carrying Out the Invention

[0029] Hereinafter, examples of embodiments of the present invention will be described with reference to the drawings. However, it goes without saying that the forms to which the present invention is applicable are not limited to the following embodiments. The three orthogonal axes XYZ shown in the drawings commonly indicate the directions of the device.

[0030] FIG. 1 is a side view showing a configuration example of the game device 10 of the present embodiment. The game device 10 is a device for simulating the behavior of an automobile and executing a car racing game. The game device 10 includes, in a housing 11, a seat 12 on which a player sits, a brake pedal 14, an accelerator pedal 16, a steering wheel 18, a display 40, a speaker 42, a power supply device 44, and a control unit 50. In addition, a shift lever, operation buttons, a play value payment device (for example, a coin inserter, a prepaid card reader, etc.) may be appropriately mounted.

[0031] The brake pedal 14, the accelerator pedal 16, and the steering wheel 18 are provided with sensors and switches for inputting game operations. These are installed with respect to the housing 11 so as to form a virtual driver's seat of an automobile. Then, the brake pedal 14, the accelerator pedal 16, and the steering wheel 18 output detection signals corresponding to the operation amounts to the control unit 50, respectively.

[0032] The display 40 is realized by, for example, a liquid crystal panel display, an organic electroluminescence display, a projector, or the like. The display 40 receives a video signal from the control unit 50 and displays the video of the game screen.

[0033] The speaker 42 receives an audio signal from the control unit 50 and emits game sounds (for example, sound effects, BGM, operation sounds, operation guidance voice, etc.).

[0034] The control unit 50 is equipped with various microprocessors such as a CPU (Central Processing Unit) 51, a GPU (Graphics Processing Unit), and a DSP (Digital Signal Processor), various IC memories 52 such as VRAM, RAM, and ROM, and an interface IC 57. The interface IC 57 controls the signal exchange between the brake pedal 14, the accelerator pedal 16, the steering wheel 18, the display 40, the speaker 42, etc. and the control unit 50.

[0035] Then, the control unit 50 executes the program stored in the IC memory 52, controls the progress of the game based on the detection signals of the operation inputs input from the brake pedal 14, the accelerator pedal 16, and the steering wheel 18. Then, it generates a video signal of the game screen, outputs it to the display 40, and displays the game screen. Also, it generates an audio signal of the game sound, outputs it to the speaker 42, and emits the game sound.

[0036] FIG. 2 is a diagram showing a configuration example of the functional units realized by the control unit 50 and examples of the programs and data stored in the control unit 50. The control unit 50 stores the program 60, the game initial setting data 62, and the game control data 64 in the IC memory 52.

[0037] The game initial setting data 62 stores data for setting a race course by arranging background objects in a three-dimensional virtual space, object model data of automobiles (game objects) running on the race course, initial setting values of the capabilities of the automobiles, and the like.

[0038] The game control data 64 stores 1) course parameter values indicating the state of the race course, 2) running state parameter values such as the position coordinates, attitude, speed, and acceleration of each automobile. Also, 3) status parameter values such as the wear values of each part of the tire, engine, and body of each automobile, 4) remaining play time, 5) game score parameter values, and the like. Of course, data other than these may also be stored as appropriate. For example, if there is a rule that items can be used during the race, parameter values regarding the types and remaining numbers of usable items may also be stored.

[0039] The control unit 50 realizes the functions as the calibration control unit 70 and the game control unit 72 by executing the program 60 with the CPU 51.

[0040] The calibration control unit 70 executes calibration related to the brake based on the detection signal of the sensor related to the brake pedal 14 in a non-operation state where the brake pedal 14 is not being operated. For example, the voltage value of the detection signal of the sensor related to the brake pedal 14 in the standby state before the start of game play is stored in the brake calibration data 66 as the zero-point voltage value of the brake operation.

[0041] Note that part or all of the functions mounted on the control unit 50 may be realized by an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a SoC (System on a Chip).

[0042] FIG. 3 is a perspective external view showing a configuration example of a pedal assembly 100 including a brake pedal 14. FIG. 4 is an XZ cross-sectional view taken along the XZ plane showing an internal structure example of the pedal assembly 100.

[0043] As shown in FIGS. 3 and 4, the pedal assembly 100 includes a case portion 102, a pedal portion 110, a pedal support mechanism 120, a support 130, an elastic body 140, and a load cell 160.

[0044] The case portion 102 defines an internal space by opposing two sheet metal members with a spacer 103 interposed therebetween and fixing them with a plurality of bolts, and integrally holds the pedal portion 110, the pedal support mechanism 120, the load cell 160, the elastic body 140, and the support 130 in a predetermined positional relationship. The case portion 102 is fixed to the inside of the housing 11 with bolts at the fixing portion 104 and is not visible to the player.

[0045] The pedal portion 110 includes a pedal plate 112 which is a portion where a player applies a stepping force as the brake pedal 14, and a pedal arm 114. The pedal plate 112 is fixed to one end of the pedal arm 114. The other end of the pedal arm 114 is fixed to the pedal support mechanism 120.

[0046] As shown in FIG. 4, the pedal arm 114 has a metal fitting 116 on its lower surface. The metal fitting 116 forms a plane facing the elastic body 140 and has a contact surface wider than the lower surface of the pedal arm 114 for contacting the elastic body 140. Note that a part of the lower surface of the pedal arm 114 may be deformed to replace the metal fitting 116. Alternatively, a part of the pedal arm 114 may be bent to replace the metal fitting 116.

[0047] In a non-operating state where no pedal operation input is made to the brake pedal 14, the pedal support mechanism 120 supports the brake pedal 14 at a position where the pedal arm 114 (metal fitting 116) does not contact the elastic body 140 and a gap G is interposed. The position of the pedal arm 114 in the non-operating state is determined by the upper surface of the pedal arm 114 hitting the stopper 105 that also serves as the spacer 103 of the case portion 102.

[0048] The pedal support mechanism 120 has a swing shaft 122 and a torsion coil spring 124. The other end of the pedal arm 114 is fixed to the swing shaft 122, and the pedal portion 110 is supported so as to be swingable in the vertical direction. In the example of FIG. 4, the other end portion of the pedal arm 114 is inserted into the recess of the swing shaft 122, and the pedal arm 114 is fixed by screwing with a bolt 126 that penetrates the swing shaft 122 from the side opposite to the recess, but the fixing method may be other than this.

[0049] One end of the torsion coil spring 124 is hung on the pedal arm 114 so as to contact the lower surface of the pedal arm 114, the coil portion is wound around the swing shaft 122, and the other end is locked to the inner surface of the case portion 102. For example, the other end may be hooked and locked to the spacer 103 of the case portion 102.

[0050] Therefore, the pedal portion 110 is supported by the pedal support mechanism 120 so as to be swingable in the vertical direction, and the pedal arm 114 is biased in the direction of pushing up the pedal plate 112 by the torsion coil spring 124. The torsion coil spring 124 applies a biasing force in a direction opposite to the operating force on the brake pedal 14.

[0051] The support tool 130 is installed below the pedal arm 114 and supports the elastic body 140 and the load cell 160 in a predetermined positional relationship. Specifically, the support tool 130 has a first plate portion 131 that supports the elastic body 140 on the upper surface, a second plate portion 132 that supports the load cell 160 on the upper surface, a hinge 133 that connects the first plate portion 131 and the second plate portion 132, and a mounting portion 134 for detachably attaching these to the case portion 102.

[0052] The first plate portion 131 and the second plate portion 132 are rectangular plate materials having long sides in the longitudinal direction of the pedal arm 114. The first plate portion 131 and the second plate portion 132 are each fixed to the blades of the hinge 133, one by one, at the end portions near the swing axis 122. The axial direction of the hinge 133 is parallel or substantially parallel to the swing axis 122. Therefore, the first plate portion 131 can swing up and down with respect to the second plate portion 132. The swinging direction thereof is along the swinging direction of the pedal arm 114 with respect to the swing axis 122.

[0053] Note that the fixing of the first plate portion 131 to the hinge 133 and the fixing of the second plate portion 132 to the hinge 133 are assumed to use small screws, but spot welding or an adhesive may also be used. The first plate portion 131 and the second plate portion 132 may be configured as the blades of the hinge 133 in the first place.

[0054] The mounting portion 134 is a sheet metal part that forms a shelf portion on the inner surface of the case portion 102, and has a burring nut portion 136 for screwing the fixing bolt 135. The mounting portion 134 is fixed to a predetermined position on the inner surface of the case portion 102 with the fixing bolt 135. And the second plate portion 132 is fixed on the shelf surface formed by fixing the mounting portion 134 to the case portion 102. For this fixing, small screws may be used, or spot welding or an adhesive may be used.

[0055] An elastic body 140 is fixed to the upper surface of the first plate portion 131. For the fixing, small screws may be used or an adhesive may be used. Focusing on the elastic body 140, it can be said that the elastic body 140 is installed between the pedal arm 114 of the pedal portion 110 and the load cell 160 by the support tool 130.

[0056] The elastic body 140 is, for example, a solid elastic body such as synthetic rubber or a hard sponge material. The elastic body 140 has a generally frustum of a square pyramid or a slightly vertically long rectangular parallelepiped shape, and has a chamfered portion 142 at the corner portion near the swing axis 122, that is, the corner portion on the side of the hinge 133 of the support tool 130 in the upper part. The chamfered portion 142 is a convex curved surface facing outward.

[0057] The load cell 160 is fixed to the upper surface (the surface facing the first plate portion 131) of the second plate portion 132 of the support 130.

[0058] The load cell 160 is fixed to the second plate portion 132 via the cell holder 162 in a posture where the load detection direction is along the vertical swing direction of the pedal portion 110. The signal line 163 of the load cell 160 is connected to the control unit 50, and the detection signal is input to the control unit 50.

[0059] The support 130 can support the elastic body 140 and the load cell 160 in a predetermined positional relationship while having a simple structure. Due to the simple structure, it is difficult to fail and can be realized at low cost.

[0060] FIG. 5, FIG. 6, and FIG. 7 are diagrams for explaining the operation of the pedal assembly 100 by an operation on the brake pedal 14 (brake operation). FIG. 5 shows a non-operation state where the player is not stepping on the brake pedal 14. In the non-operation state, the pedal portion 110 is biased by the pedal support mechanism 120 so that the pedal plate 112 is lifted upward. The upper surface of the pedal arm 114 abuts against the spacer 103 and stopper 105 and stops. At this time, a gap G is generated between the fitting 116 of the pedal arm 114 and the elastic body 140. This gap G becomes the "brake play" in the actual vehicle.

[0061] In the non-operation state, stress corresponding to the operating force on the brake pedal 14 does not act on the elastic body 140 due to the gap G. However, since the loads of the elastic body 140 and the first plate portion 131 act on the load cell 160, the load cell 160 outputs a detection signal of a voltage value corresponding to this load to the control unit 50 even in the non-operation state. The calibration control unit 70 performs calibration based on the detection signal of the load cell 160 in this non-operation state.

[0062] As shown in FIG. 6, when the player depresses the brake pedal 14 to start a braking operation, the pedal unit 110 descends. When the pedal arm 114 descends and swings by the amount of the gap G, the lower surface of the fitting 116 abuts against the chamfered portion 142 of the elastic body 140. Then, the player's stepping force is transmitted to the elastic body 140 via the pedal arm 114, and the elastic body 140 begins to be compressed. The repulsive force against the compression of the elastic body 140 is transmitted to the player's foot stepping on the brake pedal 14, and the player senses the operating feel of the brake. The stepping force is transmitted to the load cell 160 via the elastic body 140 and the first plate portion 131 and is measured as a load W1.

[0063] When the player further depresses the brake pedal 14, as shown in FIG. 7, the elastic deformation of the elastic body 140 progresses and the repulsive force of the elastic body 140 further increases. The repulsive force corresponding to the depression is transmitted to the player via the pedal arm 114, giving the player a braking feel. The further increased stepping force is transmitted to the load cell 160 via the elastic body 140 and the first plate portion 131 and is measured as a load W2 (>W1).

[0064] After the pedal arm 114 and the elastic body 140 come into contact, a load exceeding the load acting in the non-operated state acts on the load cell 160. The load cell 160 outputs a voltage value exceeding the calibrated zero-point voltage value to the control unit 50. The game control unit 72 of the control unit 50 determines a braking force corresponding to the voltage value exceeding the zero-point voltage value as one of the parameter values used when controlling the movement of the player's automobile (game object), and controls the movement of the player's automobile.

[0065] Since the load cell 160 directly receives the stepping force when the player depresses the brake pedal 14, it can detect the braking operation amount with a higher resolution than a configuration that detects the swing of the brake pedal 14 as a rotational motion as in the prior art. This also contributes to the effect of preventing fluctuations in the detected load when the elastic body 140 is directly brought into contact with the load cell 160 by the first plate portion 131 receiving the load that the elastic body 140 receives from the pedal arm 114 as a rigid surface and transmitting it to the load cell 160.

[0066] Therefore, it becomes possible to reliably and highly accurately detect a small braking operation and reflect it in game control.

[0067] In addition, in the game device 10, the durability of the elastic body 140 can be improved, and the effect of reducing the frequency of consumable replacement can be obtained. That is, focusing on the action of the load on the elastic body 140, the load acts from an obliquely upward direction on the corner near the swing axis 122 of the elastic body 140. Therefore, the elastic body 140 undergoes both tilting deformation and compressive deformation at the same time, and as the depression progresses, the position of the action point shifts. If the chamfered portion 142 is not provided on the elastic body 140, that is, in the so-called "pin angle" state, the load concentrates on the corner, and combined with the subsequent shift of the load action point position, the load acts on the elastic body 140 so as to fold the corner. As a result, chipping and extreme wear occur at the corner of the elastic body 140 early. And the chipping leads to further stress concentration, leading to further chipping and wear induction.

[0068] However, in the game device 10, the chamfered portion 142 is provided on the elastic body 140, and there is almost no shearing action that would flatten the "pin angle". Also, as the depression progresses, the position of the load action point moves so as to slide along the chamfered portion 142, so the load hardly acts to shear around the chamfered portion 142. Therefore, the concentration of the load on the corner of the elastic body 140 and the subsequent corner wear as described above do not occur, and the durability of the elastic body 140 can be improved compared to the case where the chamfered portion 142 is not provided.

[0069] Also, focusing on the contact area between the pedal arm 114 and the elastic body 140, as the depression progresses and the elastic deformation of the elastic body 140 progresses, the contact surface between the two expands. If the metal fitting 116 is not provided, the contactable area is limited to the lower surface width of the pedal arm 114. When the contact area exceeds the lower surface width of the pedal arm 114, the corners of the lower surface of the pedal arm 114 come into contact with the elastic body 140, resulting in stress concentration that induces chipping.

[0070] However, in the game device 10, the metal fitting 116 increases the contact area with the elastic body 140. Therefore, even if the depression progresses and the contact surface expands as the elastic body 140 elastically deforms, surface contact is always maintained, and stress concentration that induces chipping at the corners of the elastic body 140 does not occur. The durability of the elastic body 140 can be improved compared to the case where the metal fitting 116 is not provided.

[0071] In addition, in the game device 10, even when it becomes necessary to replace the elastic body 140 or the load cell 160, the effect of facilitating the replacement work can be obtained. That is, the elastic body 140 and the load cell 160, which are assumed to be consumables, are integrally fixed to the case portion 102 by the attachment portion 134 with the support tool 130. Therefore, when it becomes necessary to replace the elastic body 140 or the load cell 160, it can be repaired simply by removing and replacing the entire support tool 130. Component replacement during a failure is easy, the labor cost required for component replacement work can be kept low, and the time required for maintenance can also be shortened.

[0072] [Modification Example] As described above, examples of the embodiments to which the present invention is applied have been described. However, the forms to which the present invention can be applied are not limited to the above forms, and components can be added, omitted, or changed as appropriate.

[0073] (Modification Example 1) For example, in the case of a game that requires pedal operation, the game genre is not limited to a game that simulates driving a car. For example, a game that simulates flying a plane, a game that simulates riding a motorcycle, or a game that simulates operating a robot may also be acceptable.

[0074] (Modification Example 2) Also, as shown in FIG. 8, a second elastic body 170 may be provided between the first plate portion 131 and the second plate portion 132. The second elastic body 170 may be a solid elastic body such as synthetic rubber or hard sponge, or may be a coil spring, a leaf spring, or the like.

[0075] The height of the second elastic body 170 from the upper surface of the second plate portion 132 is set so as to support the relative position between the first plate portion 131 and the second plate portion 132 in the non-operated state at a position where the self-weight of the elastic body 140 does not act on the load cell 160. By preparing a plurality of types of second elastic bodies 170 having different elastic characteristics and shapes and making them interchangeable, it becomes possible to customize the feel of the brake on-site.

[0076] Further, the position where the support tool 130 is fixed to the case portion 102 may be made variable. For example, the insertion hole 106 of the fixing bolt 135 provided in the case portion 102 is formed as an elongated hole, and the relative distance between the support tool 130 and the swing shaft 122 can be changed by changing the tightening position of the fixing bolt 135. According to this configuration, at the operation site of the game device 10, the lever ratio for transmitting the operating force to the pedal portion 110 to the elastic body 140 can be changed to easily customize the brake touch. Also, when there is slack in the elastic body 140, by changing the fixing position of the support tool 130 to compensate for the deterioration of the brake touch due to the slack, the frequency of component replacement can be reduced. It is preferable to provide a scale 107 for discriminating the default position of the support tool 130 on the case portion 102.
