Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, the reaction force applying device disclosed in Patent Document 1 is attached to the vehicle at a position separated from the accelerator device by a predetermined distance. That is, the reaction force applying device and the accelerator device are attached to different positions on the vehicle floor, respectively. Therefore, there is a possibility that the deviation of the contact point between the lever of the reaction force applying device and the arm of the accelerator device increases. As a result, the amount of reaction force deviation with respect to the target reaction force increases, which may lead to a deterioration in the feeling of driver notification by reaction force such as danger notification or fuel consumption improvement notification to the driver.

[0006] An object of the present invention is to provide a reaction force applying device capable of suppressing an increase in the amount of reaction force deviation with respect to a target reaction force.

Means for Solving the Problems

[0007] The present invention relates to a reaction force applying device capable of applying a reaction force to a pedal of an accelerator device (100) including a pedal (120) depressed by a driver and a pedal housing (110) that rotatably supports the pedal and can be attached to a vehicle (1), the reaction force applying device including an actuator housing (20), an actuator (30), a lever (40), connected parts (61, 62, 63), and connecting parts (71, 72, 73). Here, "attachable to the vehicle" means not only the case where it can be directly attached to the vehicle but also the case where it can be indirectly attached to the vehicle via other members (the same applies hereinafter).

[0008] The actuator housing is attachable to the vehicle. The actuator is provided in the actuator housing. The lever is provided in the actuator housing, rotates by a driving force from the actuator, abuts against a pedal or an arm (50) that rotates together with the pedal, and can apply a reaction force to the pedal against the driver's depressing force.

[0009] The connected parts are provided in the pedal housing. The connecting parts are provided in the actuator housing and are connected to the connected parts.

[0010] In the present invention, the connected part provided in the pedal housing of the accelerator device and the connecting part provided in the actuator housing of the reaction force applying device are connected. Therefore, in attaching to the vehicle, variations in the relative positions of the pedal housing and the actuator housing can be reduced. Thereby, the deviation of the contact point between the lever of the reaction force applying device and the pedal or the arm of the accelerator device can be made small. Accordingly, the amount of reaction force deviation with respect to the target reaction force can be reduced. Thus, deterioration of the feeling of driver notification due to the reaction force can be suppressed. Actuator housing and Pedal housing are formed separately and are spaced apart from each other in a vehicle A position separated by a predetermined distance is attached to Is attached. The space inside the actuator housing and the space inside the pedal housing are independent without communicating with each other.

Mode for Carrying Out the Invention

[0012] Hereinafter, a reaction force applying device according to a plurality of embodiments and an accelerator device to which the same is applied will be described with reference to the drawings. In a plurality of embodiments, substantially the same constituent parts are denoted by the same reference numerals, and the description thereof will be omitted.

[0013] (First Embodiment) The reaction force applying device according to the first embodiment and the accelerator device to which the same is applied are shown in FIGS. 1 and 2.

[0014] The accelerator device 100 is mounted on the vehicle 1 and is used to detect the accelerator opening corresponding to the rotation angle of the pedal 120 depressed by the driver and to control the running state of the vehicle 1. The accelerator device 100 adopts an electronic throttle system and is not mechanically connected to the throttle device of the vehicle 1. The accelerator device 100 transmits information regarding the accelerator opening corresponding to the rotation angle of the pedal 120 to an electronic control unit (hereinafter referred to as "ECU") (not shown). The ECU controls the throttle device based on the accelerator opening transmitted from the accelerator device 100. Thereby, the running state of the vehicle 1 is controlled.

[0015] The reaction force applying device 10 is mounted on the vehicle 1 together with the accelerator device 100 and can apply a reaction force F2 to the pedal 120 of the accelerator device 100 against the depressing force F1 of the driver. The reaction force applying device 10 can perform driver notifications such as danger notifications and fuel consumption improvement notifications to the driver by applying a reaction force to the pedal 120 of the accelerator device 100. Further, the reaction force applying device 10 can make the pedal 120 into a footrest by restricting the rotation of the pedal 120.

[0016] The accelerator device 100 includes a pedal housing 110, a pedal 120, etc. The pedal housing 110 has a housing main body 111 and a housing attachment portion 112. The housing main body 111 forms a space inside that can accommodate components. The housing attachment portion 112 is formed integrally with the housing main body 111 so as to protrude from the housing main body 111. In the present embodiment, for example, three housing attachment portions 112 are formed (see FIG. 2). Bolt holes 113 are formed in the housing attachment portion 112. The pedal housing 110 is attached to the floor panel 2 of the vehicle 1 by passing, for example, mounting bolts 3 through the bolt holes 113 and screwing them into the floor panel 2 of the vehicle 1 to fix the housing attachment portion 112 to the floor panel 2.

[0017] In FIG. 1, the x-axis indicates the traveling direction of the vehicle 1, the y-axis indicates the vehicle width direction, and the z-axis indicates the vertically upward direction. Hereinafter, unless otherwise specified, the shape or configuration of the accelerator device 100 and the reaction force applying device 10 in the attached state to the vehicle 1 will be described. For example, "upward" or "upper side" means the upward or upper side in the state where the accelerator device 100 or the reaction force applying device 10 is attached to the vehicle 1. In the present embodiment, the floor panel 2 has a wall surface 7 parallel to the yz plane.

[0018] One end of the pedal 120 is rotatably supported by the housing main body 111 of the pedal housing 110 so as to rotate around the rotation axis Ax1. A pad 121 that is stepped on by the driver is provided at the other end of the pedal 120. An accelerator opening sensor (not shown) is provided on the rotation axis Ax1 inside the housing main body 111. The accelerator opening sensor detects the accelerator opening corresponding to the rotation angle of the pedal 120 that rotates by the driver's stepping operation and transmits it to the ECU. Note that the rotation axis Ax1 is set to be orthogonal to the z-axis and the x-axis and parallel to the y-axis.

[0019] A pedal biasing member (not shown) is provided inside the housing main body 111 of the pedal housing 110. The pedal 120 is biased in the accelerator closing direction by the pedal biasing member. The pedal housing 110 has a stopper that restricts the rotation of the pedal 120 in the accelerator closing direction and a stopper that restricts the rotation in the accelerator opening direction. The pedal 120 is rotatable within a range where it contacts both stoppers. FIG. 1 shows a state where the pedal 120 is in contact with the stopper in the accelerator closing direction, that is, a state of full accelerator closure.

[0020] <1>As shown in FIGS. 1 and 2, the reaction force applying device 10 includes an actuator housing 20, an actuator 30, a lever 40, a connected portion 61, and a connecting portion 71.

[0021] The actuator housing 20 can be attached to the vehicle 1. The actuator 30 is provided in the actuator housing 20. The lever 40 is provided in the actuator housing 20, rotates by the driving force from the actuator 30, abuts against the arm 50 that rotates together with the pedal 120, and can apply a reaction force against the driver's stepping force to the pedal 120.

[0022] More specifically, the actuator housing 20 has a housing main body 201, a pedestal portion 21, and an actuator-side extension portion 22. The housing main body 201 forms a space for accommodating the actuator 30 and the like inside.

[0023] The pedestal portion 21 has a pedestal portion main body 211 and pedestal legs 212. The pedestal portion main body 211 is integrally formed in a plate shape with the housing main body 201. Two pedestal legs 212 are provided, one at each of both ends in the plate surface direction (z-axis direction in FIG. 1) of the pedestal portion main body 211. The pedestal legs 212 are integrally formed with the pedestal portion main body 211 so as to extend obliquely in the plate thickness direction from the pedestal portion main body 211.

[0024] The actuator housing 20 is attached to the floor panel 2 by fixing the pedestal legs 212 of the pedestal portion 21 to the wall surface 7 of the floor panel 2 with the vehicle body side bolts 4 provided on the floor panel 2 of the vehicle 1, for example, and nuts 5 that are screwed onto the vehicle body side bolts 4. The attachment of the reaction force applying device 10 including the actuator housing 20 to the vehicle 1 will be described later.

[0025] The actuator-side extension portion 22 is integrally formed with the pedestal portion main body 211 so as to extend downward from the pedestal portion main body 211 of the pedestal portion 21. The actuator-side extension portion 22 is formed in a substantially L-shaped plate shape, for example, such that the end on the side opposite to the pedestal portion main body 211 is bent (see FIG. 2).

[0026] The actuator 30 is, for example, an electric motor and is housed within the housing main body 201 of the actuator housing 20. The actuator 30 can output torque as a driving force when energized. The ECU can control the energization to the actuator 30 and control the operation of the actuator 30. A speed reducer composed of a plurality of gears (not shown) is provided within the housing main body 201. The speed reducer can reduce and output the torque of the actuator 30.

[0027] One end of the lever 40 is rotatably supported by the actuator housing 20 so as to rotate around the rotation axis Ax3. One end of the lever 40 is connected to the speed reducer within the housing main body 201. The lever 40 rotates around the rotation axis Ax3 by the driving force from the actuator 30 output from the speed reducer.

[0028] In this embodiment, the arm 50 is provided on the accelerator device 100. The arm 50 is formed in a bent rod shape and is attached to the pedal 120 such that one end is fixed to the pedal 120. Thereby, the arm 50 can rotate together with the pedal 120. Therefore, the rotation axis Ax2 of the arm 50 coincides with the rotation axis Ax1 of the pedal 120.

[0029] The other end of the lever 40, that is, the end on the side opposite to the rotation axis Ax3, can abut against the other end of the arm 50, that is, the end on the side opposite to the pedal 120. The lever 40 rotates by the driving force from the actuator 30, abuts against the other end of the arm 50 that rotates together with the pedal 120, and can apply the reaction force F2 to the pedal 120 via the arm 50 by applying the reaction force F2 to the arm 50 with respect to the driver's stepping force F1.

[0030] The connected portion 61 is provided on the pedal housing 110. The connecting portion 71 is provided on the actuator housing 20 and is connected to the connected portion 61.

[0031] <2>In this embodiment, two connected parts 61 are provided. Two connecting parts 71 are provided.

[0032] More specifically, the pedal housing 110 is provided with a pedal-side extension 23. The pedal-side extension 23 is formed integrally with the housing body 111 of the pedal housing 110 so as to extend upward from the housing body 111. The pedal-side extension 23 is formed, for example, in a rectangular plate shape (see FIGS. 1 and 2). The pedal-side extension 23 is formed so as to be able to contact the end portion on the side opposite to the pedestal portion 21 of the actuator-side extension 22.

[0033] Two connected parts 61 are formed at two locations on the pedal-side extension 23, that is, two are formed. Two connecting parts 71 are formed at two locations, that is, two, at the end portion on the side opposite to the pedestal portion 21 of the actuator-side extension 22. The two connecting parts 71 are connected by contacting the two connected parts 61 respectively (see FIGS. 3 and 4).

[0034] <4>This embodiment further includes a bolt 80 for fastening the connected part 61 and the connecting part 71.

[0035] More specifically, as shown in FIG. 4, the bolt 80 has a bolt shaft portion 81 and a bolt head portion 82. The bolt shaft portion 81 is formed in a rod shape, and a male screw groove is formed on the outer peripheral wall. The bolt head portion 82 is provided integrally with the bolt shaft portion 81 at one end of the bolt shaft portion 81. The outer diameter of the bolt head portion 82 is larger than the outer diameter of the bolt shaft portion 81.

[0036] At a position corresponding to the connection portion 71 of the actuator-side extension portion 22, a bolt hole portion 221 penetrating the actuator-side extension portion 22 in the plate thickness direction is formed. That is, the periphery of the bolt hole portion 221 in the actuator-side extension portion 22 corresponds to the connection portion 71. At a position corresponding to the connected portion 61 of the pedal-side extension portion 23, a bolt hole portion 231 is formed. That is, the periphery of the bolt hole portion 231 in the pedal-side extension portion 23 corresponds to the connected portion 61. A female screw groove is formed on the inner peripheral wall of the bolt hole portion 231. The bolt 80 fastens the connected portion 61 and the connection portion 71 by passing the bolt shaft portion 81 through the bolt hole portion 221 and screwing it into the bolt hole portion 231, and locking the bolt head portion 82 to the actuator-side extension portion 22.

[0037] When the connected portion 61 and the connection portion 71 are connected and the connected portion 61 and the connection portion 71 are fastened by the bolt 80, the relative position between the pedal housing 110 and the actuator housing 20 is defined.

[0038] Next, the procedure for attaching the accelerator device 100 and the reaction force applying device 10 to the vehicle 1 and assembling the accelerator device 100 and the reaction force applying device 10 will be described.

[0039] In the present embodiment, first, the accelerator device 100 is attached to the vehicle 1 by fixing the pedal housing 110 to the floor panel 2 with the mounting bolts 3. Then, the accelerator device 100 and the reaction force applying device 10 are assembled. Specifically, the connected portion 61 on the accelerator device 100 side and the connection portion 71 on the reaction force applying device 10 side are connected, and the connected portion 61 and the connection portion 71 are fastened by the bolt 80.

[0040] Thereafter, the reaction force applying device 10 is attached to the vehicle 1 by fixing the actuator housing 20 to the floor panel 2. Specifically, each of the two vehicle body side bolts 4 is passed through each of the two mounting hole portions 213 formed in the pedestal leg portion 212 of the actuator housing 20, and a nut 5 is screwed onto the vehicle body side bolt 4 to fix the pedestal leg portion 212 to the floor panel 2, thereby attaching the reaction force applying device 10 to the vehicle 1 (see FIG. 5).

[0041] By the above procedure, the attachment of the accelerator device 100 and the reaction force applying device 10 to the vehicle 1 and the assembly of the accelerator device 100 and the reaction force applying device 10 are completed.

[0042] As shown in FIG. 5, the inner diameter of the mounting hole portion 213 is larger by the sum of the difference between the inner diameter of the bolt hole 113 formed in the housing mounting portion 112 of the pedal housing 110 and the outer diameter of the threaded portion of the mounting bolt 3 with respect to the outer diameter of the vehicle body side bolt 4, the positional variation between the bolt hole 113 and the connected portion 61 and the bolt hole portion 231, and the positional variation between the connecting portion 71 and the bolt hole portion 221 and the mounting hole portion 213. Therefore, the tolerances of each part can be absorbed on the actuator housing 20 side, and the attachment of the accelerator device 100 and the reaction force applying device 10 to the vehicle 1 and the assembly of the accelerator device 100 and the reaction force applying device 10 are facilitated.

[0043] As described above, <1> in the present embodiment, the connected portion 61 is provided in the pedal housing 110. The connecting portion 71 is provided in the actuator housing 20 and is connected to the connected portion 61.

[0044] In the present embodiment, the connected portion 61 provided in the pedal housing 110 of the accelerator device 100 and the connecting portion 71 provided in the actuator housing 20 of the reaction force applying device 10 are connected. Therefore, in the attachment to the vehicle 1, the variation in the relative position between the pedal housing 110 and the actuator housing 20 can be reduced. As a result, the deviation of the contact point between the lever 40 of the reaction force applying device 10 and the arm 50 of the accelerator device 100 can be reduced. Therefore, the reaction force deviation amount with respect to the target reaction force can be reduced. Thus, the deterioration of the feeling of driver notification due to the reaction force can be suppressed.

[0045] Also, <2> in the present embodiment, two connected portions 61 are provided. Two connecting portions 71 are provided. Therefore, the relative rotation between the pedal housing 110 and the actuator housing 20 is suppressed, and the variation in the relative position between the two can be further reduced.

[0046] Further, <4>this embodiment further includes a bolt 80 that fastens the connected portion 61 and the connecting portion 71. Therefore, even after the assembly of the accelerator device 100 and the reaction force applying device 10, the connection between the connected portion 61 and the connecting portion 71 is maintained, and variations in the relative positions of the pedal housing 110 and the actuator housing 20 can be reduced over a long period.

[0047] (Second Embodiment) A part of the reaction force applying device and the accelerator device according to the second embodiment is shown in FIGS. 6 and 7. In the second embodiment, the configurations of the connected portion and the connecting portion are different from those of the first embodiment.

[0048] In this embodiment, a press-fitting hole portion 222 is formed in the actuator-side extension portion 22 instead of the bolt hole portion 221. The press-fitting hole portion 222 is formed in a rectangular shape so as to penetrate the actuator-side extension portion 22 in the plate thickness direction at an end portion of the actuator-side extension portion 22 opposite to the pedestal portion 21. A connecting portion 72 is formed on the inner wall of the press-fitting hole portion 222 and around the press-fitting hole portion 222. That is, the inner wall of the press-fitting hole portion 222 and the periphery around the press-fitting hole portion 222 in the actuator-side extension portion 22 correspond to the connecting portion 72.

[0049] A connected portion 62 is formed in the pedal-side extension portion 23 instead of the bolt hole portion 231. The connected portion 62 is formed to protrude in a rectangular column shape in the plate thickness direction from the surface of the pedal-side extension portion 23 on the actuator-side extension portion 22 side.

[0050] <3>The connecting portion 72 has a rectangular cross-sectional shape, that is, a non-circular shape, by a plane perpendicular to the plate thickness direction of the actuator-side extension portion 22. The connected portion 62 has a rectangular cross-sectional shape, that is, a non-circular shape, by a plane perpendicular to the plate thickness direction of the pedal-side extension portion 23.

[0051] <5>In this embodiment, the connected portion 62 and the connecting portion 72 are connected by press-fitting.

[0052] More specifically, when assembling the accelerator device 100 and the reaction force applying device 10, the connected portion 62 is press-fitted into the press-fitting hole portion 222, that is, the connecting portion 72. Thereby, the connection between the connected portion 62 and the connecting portion 72 is completed, and the assembly of the accelerator device 100 and the reaction force applying device 10 is completed.

[0053] As described above, <3> the cross-sectional shape of the connected portion 62 is a non-circular shape. The cross-sectional shape of the connecting portion 72 is a non-circular shape. Therefore, the relative rotation between the pedal housing 110 and the actuator housing 20 can be suppressed, and the variation in the relative position between the two can be further reduced.

[0054] Also, <5> in the present embodiment, the connected portion 62 and the connecting portion 72 are connected by press-fitting. Therefore, the connected portion 62 and the connecting portion 72 can be easily connected, and even after the assembly of the accelerator device 100 and the reaction force applying device 10, the connection between the connected portion 62 and the connecting portion 72 is maintained, and the variation in the relative position between the pedal housing 110 and the actuator housing 20 can be reduced over a long period.

[0055] (Third Embodiment) A part of the reaction force applying device and the accelerator device according to the third embodiment is shown in FIGS. 8 and 9. The third embodiment is different from the second embodiment in the configuration of the connected portion and the connecting portion.

[0056] In the present embodiment, a snap-fit hole portion 223 is formed in the actuator side extension portion 22 instead of the press-fitting hole portion 222. The snap-fit hole portion 223 is formed in a rectangular shape so as to penetrate the actuator side extension portion 22 in the plate thickness direction at an end portion of the actuator side extension portion 22 opposite to the pedestal portion 21. A connecting portion 73 is formed on the inner wall of the snap-fit hole portion 223 and around the snap-fit hole portion 223. That is, the inner wall of the snap-fit hole portion 223 and the periphery of the snap-fit hole portion 223 in the actuator side extension portion 22 correspond to the connecting portion 73.

[0057] On the pedal side extension 23, a connected part 63 is formed instead of the connected part 62. The connected part 63 has a connected part main body 631 and an engaging part 632. The connected part main body 631 is formed to project in a rectangular column shape in the plate thickness direction from the surface of the pedal side extension 23 on the actuator side extension 22 side. Two connected part main bodies 631 are formed on the pedal side extension 23. The end of the connected part main body 631 on the side opposite to the pedal side extension 23 is inserted into the snap fit hole part 223 so as to project from the actuator side extension 22.

[0058] The size d1 of the snap fit hole part 223 in the z-axis direction is substantially the same as the size d2 of the connected part main body 631 in the z-axis direction (see Fig. 8). The size d3 of the snap fit hole part 223 in the y-axis direction is larger than the size d4 between the outer walls of the two connected part main bodies 631 that do not face each other in the y-axis direction (see Fig. 9).

[0059] The engaging part 632 is formed integrally with the connected part main body 631 so as to project in a direction away from each other in the y-axis direction from the ends of the two connected part main bodies 631 on the side opposite to the pedal side extension 23. The engaging part 632 has an inclined surface 633 and an engaging surface 634. The inclined surface 633 is formed in a rectangular planar shape so as to be inclined with respect to the xz plane. The engaging surface 634 is formed in a rectangular planar shape so as to be parallel to the yz plane. One end of the inclined surface 633 in the x-axis direction is connected to the connected part main body 631, and the other end of the inclined surface 633 in the x-axis direction is connected to the engaging surface 634. One end of the engaging surface 634 in the y-axis direction is connected to the inclined surface 633, and the other end of the engaging surface 634 in the y-axis direction is connected to the connected part main body 631 (see Fig. 9).

[0060] <3>The cross-sectional shape of the connecting part 73 by a plane perpendicular to the plate thickness direction of the actuator side extension 22 is rectangular, that is, non-circular. The cross-sectional shape of the connected part 63 by a plane perpendicular to the plate thickness direction of the pedal side extension 23 is rectangular, that is, non-circular.

[0061] <6>In this embodiment, the connected part 63 and the connecting part 73 are connected by snap fit.

[0062] More specifically, when assembling the accelerator device 100 and the reaction force applying device 10, the connected portion 63 is inserted into the snap-fit hole portion 223, that is, the connecting portion 73. At this time, for the connected portion 63, the two inclined surfaces 633 slide on the inner wall of the snap-fit hole portion 223, and the ends of the two connected portion main bodies 631 on the side opposite to the pedal side extension portion 23 are deformed so as to approach each other in the y-axis direction. When the actuator side extension portion 22 and the pedal side extension portion 23 come into contact with each other, the deformation of the two connected portion main bodies 631 returns to the original state, and the engaging surface 634 engages with the periphery of the snap-fit hole portion 223 on the surface of the actuator side extension portion 22 opposite to the pedal side extension portion 23, that is, the connecting portion 73. Thereby, the connection between the connected portion 63 and the connecting portion 73 is completed, and the assembly of the accelerator device 100 and the reaction force applying device 10 is completed.

[0063] As described above, <3> the cross-sectional shape of the connected portion 63 is a non-circular shape. The cross-sectional shape of the connecting portion 73 is a non-circular shape. Therefore, similar to the second embodiment, the relative rotation between the pedal housing 110 and the actuator housing 20 can be suppressed, and the variation in the relative position between the two can be further reduced.

[0064] Also, <6> in the present embodiment, the connected portion 63 and the connecting portion 73 are connected by a snap fit. Therefore, the connected portion 63 and the connecting portion 73 can be easily and surely connected, and even after the assembly of the accelerator device 100 and the reaction force applying device 10, the connection between the connected portion 63 and the connecting portion 73 can be maintained, and the variation in the relative position between the pedal housing 110 and the actuator housing 20 can be reduced over a long period.

[0065] (Other Embodiments) In the above-described embodiment, an example is shown in which the lever 40 abuts against the arm 50 that rotates together with the pedal 120 and applies a reaction force to the pedal 120. On the other hand, in other embodiments, for example, without providing the arm 50 on the pedal 120, the lever 40 may directly abut against the pedal 120 and apply a reaction force to the pedal 120.

[0066] In addition, in the second and third embodiments, examples in which one connected portion and one connecting portion are provided respectively were shown. In contrast, <2> in other embodiments, two or more connected portions and two or more connecting portions may be provided respectively. In this case, relative rotation between the pedal housing and the actuator housing can be suppressed, and variations in the relative positions of both can be further reduced.

[0067] In addition, in the second embodiment, an example in which the connected portion and the connecting portion are connected by press-fitting was shown, and in the third embodiment, an example in which the connected portion and the connecting portion are connected by snap-fitting was shown. In contrast, in other embodiments, the connected portion and the connecting portion may be connected by press-fitting and snap-fitting.

[0068] In addition, in the second embodiment, an example in which the cross-sectional shapes of the connected portion and the connecting portion are rectangular was shown. In contrast, <3> in other embodiments, the cross-sectional shapes of the connected portion and the connecting portion may be non-circular shapes such as, for example, an elliptical shape, an oval shape, and a polygonal shape other than a rectangular shape.

[0069] In addition, in other embodiments, the wall surface of the floor panel of the vehicle to which the reaction force applying device and the accelerator device are attached does not have to be formed parallel to the yz plane. That is, the wall surface of the floor panel may be formed at any angle with respect to the vehicle.

[0070] As described above, the present disclosure is not limited to the above-described embodiments, and can be implemented in various forms without departing from the gist thereof.
