[0002] This application claims priority to U.S. Provisional Patent Application Serial No. 62 / 913,449, filed October 10, 2019, entitled “Combination Pedal Assembly for Autonomous Vehicles,” the entire contents of which are incorporated herein by reference. Technical Field

[0003] This instruction manual generally relates to pedal assemblies, and more specifically to pedal assemblies that move between an autonomous driving position and a retracted position. Background Technology

[0004] Adjustable pedal assemblies for adjusting the position of the accelerator pedal arm, clutch pedal arm, and / or brake arm to suit the vehicle driver are well known in the art. These adjustable pedal assemblies are typically conventional pedal assemblies that provide adjustability of the pedal arms independent of the main pivot point. Each user of a vehicle may have different preferences for the combined pedal positions. However, existing pedal assemblies do not allow the accelerator pedal arm, clutch pedal arm, and / or brake pedal arm to move, so that the floor is not obstructed by the pedal assembly, allowing the user's legs and feet to extend during autonomous driving.

[0005] Therefore, a pedal assembly needs to be configured to move during autonomous driving so that users can use the floorboards without obstruction. Summary of the Invention

[0006] In one embodiment, a pedal assembly is provided. The pedal assembly includes a lower housing, a receiving cavity, and a pedal arm. The lower housing has a upper surface. The receiving cavity is positioned within the lower housing such that at least a portion of the receiving cavity is positioned below the upper surface in a vertical direction relative to the pedal assembly. The pedal arm has a pedal pad. The pedal arm is movable between a retracted position and a used position, wherein in the retracted position, the pedal pad is positioned in the receiving cavity and below the upper surface in a vertical direction relative to the pedal assembly, thereby preventing access to the pedal pad. In the used position, the pedal pad is positioned above the receiving cavity and the upper surface in a vertical direction relative to the pedal assembly, thereby allowing access to the pedal pad.

[0007] In another embodiment, a combined pedal assembly is provided. The combined pedal assembly includes a lower housing, at least one receiving cavity, a first pedal arm, and a second pedal arm. The lower housing has an upper surface. The at least one receiving cavity is positioned within the lower housing such that at least a portion of the at least one receiving cavity is positioned below the upper surface in the vertical direction of the pedal assembly. The first pedal arm has a first pedal pad. The first pedal arm is movable between a retracted position and a use position. The second pedal arm has a second pedal pad. The second pedal arm is movable between a retracted position and a use position. In the retracted position, the first pedal pad and the second pedal pad are positioned in the at least one receiving cavity and below the upper surface in the vertical direction of the pedal assembly, such that access to the first pedal pad and the second pedal pad is prohibited. In the use position, the first pedal pad and the second pedal pad are positioned above the at least one receiving cavity and the upper surface in the vertical direction of the pedal assembly, such that access to the first pedal pad and the second pedal pad is permitted.

[0008] In another embodiment, a pedal assembly is provided. The pedal assembly includes a base plate, a lower housing, a receiving cavity, and a pedal arm. The lower housing is at least partially positioned below the base plate in the vertical direction of the pedal assembly. At least a portion of the receiving cavity is positioned below the base plate in the vertical direction of the pedal assembly. The pedal arm has a pedal pad. The pedal arm is movable between a retracted position and a used position. In the retracted position, the pedal pad is positioned in the receiving cavity and below the base plate in the vertical direction of the pedal assembly, thereby preventing access to the pedal pad. In the used position, the pedal pad is positioned above the receiving cavity and the base plate in the vertical direction of the pedal assembly, thereby allowing access to the pedal pad.

[0025] Embodiments of the present invention relate to a pedal assembly for moving at least one pedal between a use position and a retracted position. The use position is a position where a user can approach the pedals during vehicle operation to allow pivotal movement of the at least one pedal. The retracted position is a position where the at least one pedal is positioned below the vehicle floor and operation by the user is prohibited. Furthermore, when in the use position, at least one pedal can be adjusted between multiple positions to suit the user's needs. The pedal assembly includes an upper housing and an opposing lower housing, and at least one pedal. The at least one pedal may be an accelerator pedal, a brake pedal, and / or a clutch pedal. The at least one pedal includes an elongated member having a pedal pad portion and an opposing pivoting end.

[0026] The pedal pad is configured for user contact, and its pivot end is pivotally coupled to the upper housing such that when the user contacts the pedal pad, the elongated member pivots relative to the upper housing about the pivot end. At least one receiving cavity is disposed within the lower housing below the upper surface and receives the pedal pad for at least one pedal when the pedal assembly is in the retracted position. When the pedal assembly is in the retracted position, the pedal pad is positioned vertically below the upper surface to prevent user contact with the pedal pad. This allows the user to use the base plate without obstruction. In the use position, the pedal pad is positioned above the upper surface of the lower housing to allow the user to contact the pedal pad to pivot or move the elongated member relative to the upper housing.

[0027] This article will describe in more detail the various implementations of the pedal assembly and the operation of the pedal assembly.

[0028] As used herein, the term "longitudinal direction" refers to the front-to-back direction of the pedal assembly (i.e., in...). Figure 1 The coordinate axes depicted in the figure are along the + / -X directions. The term "lateral direction" refers to the lateral axis direction (i.e., in the direction of the lateral axis). Figure 1 The coordinate axes depicted in the diagram are in the + / -Y direction, and are transverse to the longitudinal direction. The term "vertical direction" refers to the up-down direction of the pedal assembly (i.e., in the direction of vertical movement). Figure 1 (The coordinate axes depicted in the figure are in the + / -Z direction). As used herein, "up" or "above" is generally defined in the positive Z direction toward the coordinate axes shown in the figure. "Down" or "below" is generally defined in the negative Z direction toward the coordinate axes shown in the figure.

[0029] First refer to Figures 1 to 5 as well as Figures 8 to 12The pedal assembly 10 is schematically depicted. As discussed in more detail herein, the pedal assembly 10 includes an accelerator pedal assembly 12 and a pedal assembly 14, which are independently pivotable relative to the upper housing 16 and the lower housing 18, and movable between a used position and a retracted position. Although the pedal assembly 10 is shown as a combined pedal assembly, this is not limiting. That is, the pedal assembly 10 may include only a single pedal (i.e., an accelerator pedal, a brake pedal, and / or a clutch pedal). Furthermore, the pedal assembly 10 may include more than two pedals (i.e., an accelerator pedal, a brake pedal, and a clutch pedal).

[0030] As will be understood by those skilled in the art, the upper housing 16 and / or the lower housing 18 are coupled to at least one vehicle component 17 of the vehicle, such as an IP bracket and a fireproof wall. It should be understood that the upper housing 16 is positioned above the lower housing 18 in the vertical direction of the pedal assembly (i.e., in the + / -Z direction). Therefore, the upper housing 16 can be coupled to at least one vehicle component 17, while the lower housing 18 is coupled to another vehicle component. Furthermore, the upper housing 16 and the lower housing 18 can be coupled to each other. The upper housing 16 and the lower housing 18 can be formed from a single component (such as an integral structure) or from multiple components. The upper housing 16 and the lower housing 18 can be coupled together by welding, bolting, or any other known method. Furthermore, the pedal assembly 10 can be configured for any type of vehicle, such as a car, aircraft, ship, etc.

[0031] refer to Figures 1 to 2 , Figures 4 to 5 , Figures 8 to 9 as well as Figures 11 to 12 The upper housing 16 includes a user-facing upper surface 20 and an opposing vehicle-facing surface 22. The user-facing upper surface 20 faces a user located in the vehicle, such as a driver in a driver's seat, while the vehicle-facing surface 22 is adjacent to and / or connected to at least one vehicle component 17, such as a fireproof wall or other component of the vehicle. The upper housing 16 includes a first protrusion 47 in a direction opposite to the vehicle-facing surface 22, which extends from the user-facing upper surface 20 of the upper housing 16 in the longitudinal direction of the pedal assembly (i.e., in the + / -X direction). The first protrusion 47 includes a top wall 26, a pair of opposing side walls 28, and a front wall 30.

[0032] A top wall 26 extends from the user-facing upper surface 20 in the longitudinal direction of the pedal assembly (i.e., in the + / -X direction). A pair of opposing side walls 28 extend downward from opposing lateral edges 27 of the top wall 26 in the vertical direction of the pedal assembly (i.e., in the + / -Z direction). A front wall 30 extends downward from the front edge 31 of the top wall 26 in the vertical direction of the pedal assembly (i.e., in the + / -Z direction). Thus, the front wall 30 connects to the pair of opposing side walls 28 at an abutment 33. A pedal adjustment cavity 24 is formed within the first protrusion 47. That is, the top wall 26, the pair of opposing side walls 28, and the front wall 30 form the pedal adjustment cavity 24, which is a generally hollow internal space within the first protrusion 47. In some embodiments, the surface 22 facing the vehicle may form the rear wall of the pedal adjustment cavity 24. In other embodiments, the pedal adjustment cavity 24 opens rearward.

[0033] In some embodiments, as discussed in more detail herein, the bottom or lower portion of the pedal adjustment cavity 24 is open to allow movement of the pedal arm 32. In other embodiments, the lower wall may be positioned to connect with a pair of opposing side walls 28, a front wall 30, and a user-facing upper surface 20 to close the pedal adjustment cavity 24. Therefore, in this embodiment, as discussed in more detail herein, the lower wall includes a groove or opening to accommodate the pedal arm 32 and its movement.

[0034] Still referencing Figures 1 to 2 , Figures 4 to 5 , Figures 8 to 9 as well as Figures 11 to 12 The upper housing 16 has a pair of opposing sidewalls 28 including a first pair of elongated slots 46. The first pair of elongated slots 46 are spaced apart from each other. In some embodiments, each of the pair of elongated slots 46 extends linearly in the longitudinal direction of the pedal assembly (i.e., in the + / -X direction) between a first end 41a and a second end 41b. In other embodiments, each of the first pair of elongated slots 46 is curved. In some embodiments, the first pair of elongated slots 46 may be oriented at an angle relative to the top wall 26 in a direction downward from the user-facing upper surface 20 in the longitudinal direction of the pedal assembly (i.e., in the + / -X direction) toward the front wall 30. That is, the first end 41a of the first pair of elongated slots 46 is positioned above the second end 41b of the first pair of elongated slots 46 in the vertical direction of the pedal assembly (i.e., in the + / -Z direction), such that the first pair of elongated slots 46 are oriented at an angle.

[0035] In other embodiments, each of the first pair of elongated slots 46 may extend at a 90-degree angle (i.e., linear, without angle) relative to the top wall 26 in a direction toward the front wall 30 along the longitudinal direction of the pedal assembly (i.e., in the + / -X direction) away from the user-facing upper surface 20. That is, the first termination 41a and the second termination 41b of the first pair of elongated slots 46 are similarly positioned in the vertical direction of the pedal assembly (i.e., in the + / -Z direction) such that the orientation of the first pair of elongated slots 46 in the longitudinal direction of the pedal assembly (i.e., in the + / -X direction) is horizontal or linear. As discussed in more detail herein, each of the first pair of elongated slots 46 is configured to receive a first shaft 40 of the pedal assembly 14.

[0036] In some embodiments, the first protrusion 47 is integrally formed with the upper housing 16. That is, the first protrusion 47 and the upper housing 16 are a single structure. In other embodiments, the first protrusion 47 may be coupled to the upper housing 16 by welding, bolting, or any other known method.

[0037] The upper housing 16 also includes a second protrusion 71 in the direction opposite to the vehicle-facing surface 22, which extends from the user-facing upper surface 20 in the longitudinal direction of the pedal assembly (i.e., in the + / -X direction). The second protrusion 71 includes a top surface 71a extending from the user-facing upper surface 20, an opposing bottom surface 71c, and a pair of side surfaces 71b extending between the top surface 71a and the bottom surface 71c and both terminating at a front surface 71d. The front surface 71d faces the user. That is, the front surface 71d is a planar surface extending in the same direction as the user-facing upper surface 20, but the front surface 71d is positioned at the termination of the second protrusion 71. Therefore, the second protrusion 71 extends a length L2 from the user-facing upper surface 20 in the longitudinal direction of the pedal assembly (i.e., in the + / -X direction) and terminates at the front surface 71d, as shown below. Figure 2 As shown in the optimal diagram. The length L2 of the second protrusion 71 is less than the length L1 of the first protrusion 47 extending from the user-facing upper surface 20, as shown in the diagram. Figure 2 The best result is shown in the middle.

[0038] In some embodiments, the protrusion 73 extends from the front surface 71d in the longitudinal direction of the pedal assembly (i.e., in the + / -X direction). In some embodiments, the protrusion 73 may generally be "U-shaped". In other embodiments, the protrusion 73 may be other shapes, such as square, rectangular, triangular, hexagonal, etc. Furthermore, in some embodiments, the protrusion 73 includes a aperture 75. The aperture 75 may be configured to receive fasteners such as bolts and nuts, screws, rivets and / or J-hooks, and may be used to assist in connecting the upper housing 16 to at least one vehicle component 17 of the vehicle. For example, connecting to IP brackets and fireproof walls, or attaching wiring harnesses or other vehicle components to the aperture 75.

[0039] Still referencing Figures 1 to 2 , Figures 4 to 5 , Figures 8 to 9 as well as Figures 11 to 12 The pair of side surfaces 71b of the second protrusion 71 include a second elongated groove 70. The second elongated groove 70 may be arcuate or curved and may be curved in the vertical direction of the pedal assembly (i.e., in the + / - Z direction). That is, the second end portion 77 of the second elongated groove 70 may be located above the first end portion 81 of the second elongated groove 70 in the vertical direction of the pedal assembly (i.e., in the + / - Z direction). In some embodiments, the second elongated groove 70 extends a greater length in the longitudinal direction of the pedal assembly (i.e., in the + / - X direction) than the first pair of elongated grooves 46 extend a greater length in the longitudinal direction of the pedal assembly (i.e., in the + / - X direction).

[0040] In other embodiments, the second elongated slot 70 extends horizontally or linearly in the longitudinal direction of the pedal assembly (i.e., in the + / -X direction). In other embodiments, the second elongated slot 70 may be angled relative to the top surface 71a in a direction downward from the user-facing upper surface 20 along the longitudinal direction of the pedal assembly (i.e., in the + / -X direction) toward the front surface 71d. In other embodiments, the second elongated slot 70 may extend upward or downward from the user-facing upper surface 20 in the vertical direction of the pedal assembly (i.e., in the + / -Z direction) and at a 90-degree (linear, no angle) angle relative to the top surface 71a in the longitudinal direction of the pedal assembly (i.e., in the + / -X direction) toward the front surface 71d. As discussed in more detail herein, the second elongated slot 70 is configured to receive the second shaft 74 of the accelerator pedal assembly 12.

[0041] It should also be understood, as discussed in more detail herein, that the first pair of elongated slots 46 and the second elongated slot 70 extend in the longitudinal direction of the pedal assembly (i.e., in the + / -X direction) by the length required to facilitate movement of both the accelerator pedal assembly 12 and the pedal assembly 14 between the use position and the retracted position, wherein in the retracted position, actuation of the accelerator pedal assembly 12 and the pedal assembly 14 is prohibited.

[0042] In some embodiments, the upper housing 16 and the first protrusion 47 and the second protrusion 71 are made of plastics such as polyetheretherketone, polycarbonate, polystyrene, and polypropylene. In other embodiments, the upper housing 16 and the first protrusion 47 and the second protrusion 71 are made of metals such as aluminum, steel, and magnesium. In further embodiments, the upper housing 16 and the first protrusion 47 and the second protrusion 71 are constructed of a combination of materials including plastics and metals. For example, the upper housing 16 may be made of plastic, and the first protrusion 47 and the second protrusion 71 may be made of metal, wherein the protrusions may be attached to the upper housing 16 by fasteners or chemical attachment.

[0043] In some embodiments, the first protrusion 47 and the second protrusion 71 are integral with the upper housing 16. That is, the first protrusion 47 and the second protrusion 71 are formed as a unified or integral structure with the upper housing 16. In other embodiments, the first protrusion 47 or the second protrusion 71 is an integral structure formed with the upper housing 16, while simultaneously being attached to the upper housing 16. For example, the first protrusion 47 or the second protrusion 71 can be plastic-welded to the upper housing 16, connected by fasteners such as bolts and nuts, screws and rivets, or chemically attached via adhesives and / or epoxy resins. In other embodiments, the first protrusion 47 and the second protrusion 71 are separate components attached to the upper housing 16. For example, each or both of the first protrusion 47 and the second protrusion 71 can be plastic-welded to the upper housing, connected by fasteners such as bolts and nuts, screws, rivets, or chemically attached to the upper housing 16 via adhesives or epoxy resins.

[0044] Now for reference Figures 1 to 5 as well as Figures 8 to 12The lower housing 18 includes an upper surface 93 and at least one receiving cavity 90 positioned below the upper surface 93 in the vertical direction of the pedal assembly (i.e., in the + / -Z direction). Furthermore, the upper surface 93 may be angled and follow the contour of the lower housing 18 such that an upper portion 97a of the upper surface 93 is positioned above a lower portion 97b of the upper surface 93, and such that the upper surface 93 is positioned closer to the user-facing upper surface 20. Additionally, the lower portion 97b may terminate at different heights from the bottom surface 55 of the lower housing 18 in the vertical direction of the pedal assembly (i.e., in the + / -Z direction). As discussed in more detail herein, at least one receiving cavity 90 is configured to receive at least a portion of the pedal assembly 14 and the accelerator pedal assembly 12 when the pedal assembly 10 is in the retracted position.

[0045] Although the lower housing 18 is depicted as having at least one receiving cavity 90 as a pair of receiving cavities 90, this is not limiting. That is, the lower housing 18 may include only a single cavity for receiving a single pedal, a pair of cavities for receiving two pedals, three cavities for receiving three pedals, and so on. For example, the pedal assembly 10 may include a brake pedal, an accelerator pedal, and a clutch pedal, and at least three separate receiving cavities. Furthermore, in some embodiments, a single cavity may receive more than one pedal (i.e., a brake pedal and an accelerator pedal).

[0046] As shown in the figure, one of the at least one receiving cavity 90 corresponds to the pedal assembly 14, while the other of the at least one receiving cavity 90 corresponds to the accelerator pedal assembly 12. In some embodiments, the inner surface 92a of the at least one receiving cavity 90 corresponding to the pedal assembly 14 is angled relative to the upper surface 93 of the lower housing 18. Furthermore, in some embodiments, the inner surface 92a of the at least one receiving cavity 90 corresponding to the pedal assembly 14 includes a plurality of contour portions 94. As discussed in more detail herein, the plurality of contour portions 94 may be shaped to match the curves, angles, bends, etc., of the pedal pad 38 and pedal arm 32 of the pedal assembly 14.

[0047] Furthermore, at least one receiving cavity 90 corresponding to the accelerator pedal assembly 12 includes an inner surface 92b. The at least one receiving cavity 90 corresponding to the accelerator pedal assembly 12 is angled relative to the upper surface 93 of the lower housing 18. In some embodiments, the inner surface 92b of the at least one receiving cavity 90 corresponding to the accelerator pedal assembly 12 is angled and has no profile. In other embodiments, the inner surface 92b of the at least one receiving cavity 90 corresponding to the accelerator pedal assembly 12 includes a profile. It should be understood that, as Figures 8 to 12As best shown and discussed in more detail herein, at least one receiving cavity 90 has a depth in the vertical direction of the pedal assembly (i.e., in the + / -Z direction) from the upper surface 93 of the lower housing 18 and / or from the bottom plate surface 101 of the vehicle's bottom plate 100, allowing at least a portion of the pedal pad 38 and pedal arm 32 of the pedal assembly 14, and at least a portion of the accelerator pedal pad 68 and elongated body portion 60 of the accelerator pedal assembly 12, to retract or move below the bottom plate surface 101 in the vertical direction of the pedal assembly (i.e., in the + / -Z direction) and enter the corresponding at least one receiving cavity 90 in the retracted position. Therefore, when in the retracted position, the driver of the vehicle cannot actuate or move the accelerator pedal assembly 12 and / or the pedal assembly 14. Therefore, the pedal assembly 10 is disabled or prohibited from human use when in the retracted position.

[0048] Now return to the reference Figures 1 to 2 , Figures 4 to 5 , Figures 8 to 9 as well as Figures 11 to 12 In some embodiments, the lower housing 18 also includes a pair of third protrusions 79 spaced apart in the vertical direction of the pedal assembly (i.e., in the + / -Z direction) and extending along the user-facing lower surface 80 of the lower housing 18, respectively. Since the pair of third protrusions 79 are identical, only one of the third protrusions 79 will be described in detail.

[0049] The third protrusion 79 extends outward from the user-facing lower surface 80 along the longitudinal direction of the pedal assembly (i.e., along the + / -X direction) in a direction opposite to the vehicle-facing surface 22. The third protrusion 79 includes a top surface 79a extending from the user-facing lower surface 80, an opposing bottom surface 79c, and a pair of side surfaces 79b extending between the top and bottom surfaces 79a and terminating at a front surface 79d. The front surface 79d faces the user. That is, the front surface 79d is a planar surface extending in the same direction as the user-facing lower surface 80, but it is positioned at the termination of the second protrusion 71. In some embodiments, the top surface 79a extends from the user-facing lower surface 80 by a shorter distance than the pair of side surfaces 79b, such that the third protrusion 79 is generally rectangular. In other embodiments, the third protrusion 79 can be a shape such as a square, triangle, octagon, etc., and can be any regular or irregular shape.

[0050] Still referencing Figures 1 to 2 , Figures 4 to 5 , Figures 8 to 9 as well as Figures 11 to 12The third protrusion 79 has a pair of side surfaces 79b including a third pair of elongated grooves 78. In some embodiments, the third pair of elongated grooves 78 are generally oriented in the vertical direction of the pedal assembly (i.e., in the + / -Z direction). That is, the second end portion 83a of the third pair of elongated grooves 78 may be located above the first end portion 83b of the third pair of elongated grooves 78 in the vertical direction of the pedal assembly (i.e., in the + / -Z direction).

[0051] In other embodiments, the third pair of elongated slots 78 may be angled relative to the top surface 79a in a direction extending downward toward the front surface 71d from the user-facing lower surface 80 along the longitudinal direction of the pedal assembly (i.e., along the + / -X direction) and / or in the opposite direction. In other embodiments, the third pair of elongated slots 78 may extend in an arcuate or curved orientation relative to the top surface 79a. As discussed in more detail herein, the third pair of elongated slots 78 is configured to receive the third shaft 84 of the accelerator pedal assembly 12.

[0052] It should also be understood that, as discussed in more detail herein, the first pair of elongated slots 46, the second pair of elongated slots 70 and the third pair of elongated slots 78 are oriented and have the lengths necessary to facilitate movement of both the accelerator pedal assembly 12 and the pedal assembly 14 between the use position and the retracted position, such that actuation of the accelerator pedal assembly 12 and the pedal assembly 14 is prohibited in the retracted position.

[0053] In some embodiments, the lower housing 18 and the third protrusion 79 comprise plastic materials such as polyetheretherketone, polycarbonate, polystyrene, and polypropylene. In other embodiments, the lower housing 18 and the third protrusion 79 are made of metallic materials such as aluminum, steel, and magnesium. In further embodiments, the lower housing 18 and the third protrusion 79 are constructed from a combination of materials comprising both plastic and metal. For example, the lower housing 18 may be made of plastic, and the pair of third protrusions 79 may be made of metal, wherein the protrusions may be attached to the lower housing 18 by fasteners or chemical attachment.

[0054] In some embodiments, the third protrusion 79 is formed together with the lower housing 18. That is, the third protrusion 79 may be formed together with the lower housing 18 as a unified construction or integral structure. In other embodiments, the third protrusion 79 may be coupled to the lower housing 18 by welding, such as plastic welding, by fasteners such as bolts, screws and rivets, and / or by adhesives such as epoxy resin. In other embodiments, the third protrusion 79 extends from both the user-facing upper surface 20 of the upper housing 16 and the user-facing lower surface 80 of the lower housing 18. That is, the third protrusion 79 extends transversely through both the user-facing upper surface 20 of the housing 16 and the user-facing lower surface 80 of the lower housing 18.

[0055] Return to reference Figure 1 And now refer to Figure 3 In some embodiments, the inner surfaces 92a, 92b of at least one receiving cavity 90 each include at least one position sensor 95a, 95b. In some embodiments, at least one position sensor 95a is configured to determine or detect the presence and / or absence of the pedal pad 38 and pedal arm 32 of the pedal assembly 14 within at least one receiving cavity 90. Furthermore, in some embodiments, at least one position sensor 95b is configured to determine or detect the presence and / or absence of the accelerator pedal pad 68 and elongated body portion 60 of the accelerator pedal assembly 12 within at least one receiving cavity 90. It should be understood that at least one position sensor 95a, 95b may be a laser switch, a proximity switch, a pressure switch, etc. In some embodiments, at least one position sensor 95a, 95b is communicatively coupled to an electronic control unit (ECU) of a vehicle configured to detect the output of at least one position sensor 95a, 95b. In some implementations, the ECU disables the function of the pedal assembly 14 and / or the accelerator pedal assembly 12 when it detects that the pedal assembly 14 and / or the accelerator pedal assembly 12 is in a retracted position (i.e., within at least the receiving cavity 90).

[0056] In other embodiments, the position of the shaft within the elongated slot can be detected by at least one position sensor 95a, 95b to determine the position of the accelerator pedal assembly 12 and / or the pedal assembly 14. For example, at least one position sensor 95a, 95b can be positioned within a first pair of elongated slots 46 to determine the position of the first shaft 40. In other embodiments, at least one position sensor 95a, 95b can be positioned at a first end 41a and a second end 41b of the first pair of elongated slots 46 to determine the position of the first shaft 40. In yet another example, at least one position sensor 95a, 95b can be positioned at a first end 81 and a second end 77 within a second elongated slot 70 to determine the position of the second shaft 74. In yet another example, at least one position sensor 95a, 95b can be positioned at a first end 83a and a second end 83b within a third elongated slot 78 to determine the position of the third shaft 84.

[0057] In other embodiments, the position or revolutions of actuator 54 can be detected by at least one position sensor 95a, 95b to determine the position of accelerator pedal assembly 12 and / or pedal assembly 14. For example, at least one position sensor 95a, 95b can be positioned to detect the revolutions of actuator 54 in order to know whether accelerator pedal assembly 12 and / or pedal assembly 14 is in a retracted position or an active position.

[0058] It should be understood that in any embodiment, at least one position sensor 95a, 95b may be a laser switch, proximity switch, pressure switch, etc. In some embodiments, at least one position sensor 95a, 95b is communicatively coupled to an electronic control unit (ECU) of a vehicle configured to detect the output of at least one position sensor 95a, 95b. In some embodiments, the function of the pedal assembly 14 and / or the accelerator pedal assembly 12 is disabled by the ECU when the ECU detects that the pedal assembly 14 and / or the accelerator pedal assembly 12 is in a retracted position (i.e., within at least the receiving cavity 90).

[0059] Return to reference Figures 1 to 5 And now refer to Figures 6 to 7 The pedal assembly 14 includes a pedal arm 32 and an elongated rod 125. The elongated rod 125 may be a booster input rod. The pedal arm 32 includes an elongated body portion 34, a first hole 128, and a pivot portion 36 positioned adjacent to the upper end portion 34a of the elongated body portion 34. The pivot portion 36 includes a second hole 39. The pedal pad 38 is positioned at the opposite lower end portion 34b of the elongated body portion 34. The second hole 39 of the pivot portion 36 receives a first shaft 40. The first hole 128 is positioned between the upper end portion 34a and the lower end portion 34b and is configured to receive at least a portion of the elongated rod 125.

[0060] The first shaft 40 may be an elongated member, such as a pivot pin having a pair of flanges 43 or caps positioned at each end of the elongated member, and each pair of flanges 43 having a larger diameter than the first shaft 40. Furthermore, one of the pair of flanges 43 or one end of the first shaft 40 may include a locking device, such as a C-clamp or E-clamp that engages in a groove or channel within the first shaft 40.

[0061] The pedal assembly 14 also includes a bushing 37 and a bracket 53. The bracket can generally be U-shaped, but this is not limiting and can include a variety of different shapes, such as V-shaped, square, rectangular, etc. The bracket 53 includes a recess 57 at its front surface 63a that provides a clearance 59 between the bracket 53 and the upper end 34a of the pedal arm 32. The bracket 53 also includes a pair of holes 61 extending in the lateral direction of the pedal assembly (i.e., in the + / - Y direction) and a hole 63b extending through the front surface 63a. The pair of holes 61 receive the bushing 37 and a first shaft 40 within the bushing 37. Therefore, the pair of holes 61, the bushing 37, and the first shaft 40 allow the pivot 36 to move about the pivot axis 42 and in the direction indicated by arrow A1, such as... Figures 5-6As shown in the diagram. That is, the bushing 37 and part of the first shaft extend through the pair of holes 61, supporting the elongated body portion 34 and allowing the pivot portion 36 to move relative to the bracket 53, such that the pedal pad 38 changes orientation in the longitudinal direction of the pedal assembly (i.e., in the + / -X direction) and / or in the vertical direction of the pedal assembly (i.e., in the + / -Z direction).

[0062] The first shaft 40 forms a first pivot shaft 42, which extends in the lateral direction of the pedal assembly (i.e., in the + / - Y direction) to allow movement or rotation of the pedal arm 32 in the use position. That is, when in the use position, the pedal arm 32 pivots or rotates within the upper housing 16 about the first shaft 40 in the direction of arrow A1. Because of this, the first shaft 40 forms the first pivot shaft 42, but remains stationary within the first pair of elongated slots 46 when pressure is applied to and removed from the pedal pad 38 during use. Furthermore, the upper housing 16 directly supports the first shaft 40 within the pair of elongated slots 46.

[0063] For example, when the bushing 37 of the first shaft 40 rotates within the first pair of elongated slots 46 to obtain the desired control input of the vehicle's system, the pedal pad 38 is adapted to be pressed down by the driver to cause the pedal arm 32 to pivot about the first pivot axis 42. It should also be understood that although the pedal pad 38 is formed separately and attached to the pedal arm 32, in some embodiments, the pedal pad 38 may be formed integrally with the pedal arm 32. Referring now to... Figures 8 to 14 As discussed in more detail herein, in the retracted position, a first hole 128 located between the upper end 34a and the lower end 34b forms a retractable shaft 120, wherein the pedal arm 34 moves about the retractable shaft 120 in the direction indicated by arrow A9.

[0064] Now for reference Figures 1 to 7 The upper end portion 34a and the pivot portion 36 are both positioned within the pedal adjustment cavity 24. As discussed in more detail herein, the first shaft 40, along the first pair of elongated slots 46 in the longitudinal direction of the pedal arm (i.e., in the + / -X direction), is as follows... Figure 5 Slide or move in the direction of arrow A2 shown to move the pedal arm 32 and pedal pad 38 between the use position and the retracted position.

[0065] The accelerator pedal assembly 12 includes an accelerator arm 58 and an electronic throttle control (ETC) bracket 64. The accelerator arm 58 has an elongated body 60, a pivot 62 extending from the upper end 60a of the elongated body 60, and an accelerator pedal pad 68 located at the lower end 60b of the elongated body 60. The accelerator pedal assembly 12 also includes an ETC module 66. As discussed in more detail herein, the pivot 62 generally extends below the upper end 60a of the elongated body 60 in the vertical direction of the pedal assembly (i.e., in the + / -Z direction) and is positioned inward to extend between the ETC bracket 64 and the ETC module 66.

[0066] The upper end 60a is connected to a control device via an ETC module 66 for electronic actuation. The ETC module 66 senses the pivotable movement of the accelerator arm 58 and transmits associated electronic signals via a cable or wire connected thereto. The ETC module 66 can be of any suitable type known in the art. It should also be understood that although the accelerator pedal pad 68 is formed separately and attached to the accelerator arm 58, in embodiments, the accelerator pedal pad 68 may be formed integrally with the accelerator arm 58.

[0067] Furthermore, the ETC bracket 64 includes an upper portion 72 and a lower portion 82. The connection between the upper portion 72 of the ETC bracket 64 relative to the second axis 74 and the lower portion 82 of the ETC bracket 64 relative to the third axis 84 helps prevent the ETC bracket 64 from rotating when the accelerator pedal pad 68 is pressed and / or released. The upper end 60a is operatively connected to a control device, such as a vehicle throttle. Therefore, pivoting movement of the pivot portion 62 caused by the direct force applied to the lower end 60b and the accelerator pedal pad 68 or the release of that force causes the upper end 60a to pivot about the pivot axis 67 in the direction of arrow A3, thereby operating the control device in the desired manner.

[0068] Furthermore, a second elongated slot 70 within the second protrusion 71 is configured to engage with the upper portion 72 of the ETC bracket 64 of the accelerator pedal assembly 12 via a second shaft 74. As discussed in more detail herein, the second shaft 74 extends within the second elongated slot 70 in the lateral direction of the pedal assembly (i.e., the + / -Y direction), such that the second elongated slot 70 serves as a guide for movement of the accelerator arm 58 between the use position and the retracted position. Additionally, a third pair of elongated slots 78 within the third protrusion 79 is configured to engage with the lower portion 82 of the ETC bracket 64 of the accelerator pedal assembly 12 via a third shaft 84. As discussed in more detail herein, the third shaft 84 extends within the third pair of elongated slots 78 in the lateral direction of the pedal assembly (i.e., the + / -Y direction), such that the third pair of elongated slots 78 serves as a guide for movement of the accelerator arm 58 between the use position and the retracted position.

[0069] In some embodiments, the second shaft 74 and the third shaft 84 may be elongated members, such as pivot pins, having a pair of flanges or caps positioned at either end or both ends of the elongated member, and the flanges having a correspondingly larger diameter than the second shaft 74 and the third shaft 84. Furthermore, one of the flanges or one end of the second shaft 74 and the third shaft 84 may include locking devices, such as C-clamps and E-clamps correspondingly engaging in grooves or channels within the second shaft 74 and the third shaft 84.

[0070] Now for reference Figures 5 to 7 as well as Figures 12 to 14 The first drive assembly 48 includes, for example, an actuator 54 (such as an electric motor), a first threaded member 50, a third threaded member 122 (such as a lead screw), and a gear 124 for moving the first threaded member 50 along the shaft 56 in the direction of arrow A10. Parts of the actuator 54, the first threaded member 50, the third threaded member 122, and the gear 124 may be at least partially positioned within the pedal adjustment cavity 24 of the upper housing 16. A support member 52 for the first threaded member 50 is provided in the front wall 30 of the upper housing 16, which may be integrally formed in the upper housing 16. The first threaded member 50 is mounted to a bracket 53 through a hole 63b in the front surface 63a and positioned in a recess 57 prior to the gap 59 to extend in the longitudinal direction of the pedal assembly (i.e., in the + / -X direction).

[0071] The third threaded member 122 is an elongated member having a threaded portion adapted to engage with a gear 124 having an external thread, such that the third threaded member 122 and the gear 124 form a worm gear. In some embodiments, the third threaded member 122 is connected to an output member, such as a shaft of actuator 54 and a second actuator. In some embodiments, depending on the requirements of the pedal assembly 10, a suitable gear arrangement may be provided between the actuator 54 and the third threaded member 122 if necessary.

[0072] Gear 124 also includes a bore 130 for receiving a first threaded member 50. The first threaded member 50 can be positioned in the longitudinal direction of the pedal assembly (i.e., in the + / -X direction), perpendicular to a third threaded member 122 oriented in the transverse direction of the pedal assembly (i.e., in the + / -Y direction). The first threaded member 50 includes a plurality of external threads 132. The third threaded member 122 rotates about an axis 134 in the direction indicated by arrow A4, thereby causing the first threaded member 50 to move along an axis 56 in the direction indicated by arrow A10. In some embodiments, gear 124 is molded from a suitable plastic material such as nylon. In other embodiments, gear 124 is formed from a metal such as steel. In some embodiments, the first threaded member 50 and the third threaded member 122 are each formed from a resin such as nylon. In other embodiments, the first threaded member 50 and the third threaded member 122 are formed from a metal such as steel.

[0073] In some embodiments, the actuator 54 is positioned within one of a pair of opposing sidewalls 28 forming the pedal adjustment cavity 24. In other embodiments, it should be understood that the actuator 54 may be positioned anywhere within the pedal assembly 10. The first threaded member 50 is connected to the output member of the actuator 54, such as a shaft, in a known manner. In some embodiments, a suitable gear mechanism is provided between the actuator 54 and the first threaded member 50, depending on the requirements of the pedal assembly 10. Furthermore, in some embodiments, a suitable gear mechanism is provided between the first threaded member 50 and the pivot portion 36 of the pedal arm 32, depending on the requirements of the pedal assembly 10. Additionally, it should be understood that the actuator 54 may alternatively be located at the accelerator pedal assembly 12, and / or the accelerator pedal assembly 12 and the pedal assembly 14 may each have a separate actuator. As discussed in more detail herein, actuator 54 can be connected to suitable control circuitry having operator input devices for selectively operating actuator 54 to position accelerator pedal assembly 12 and pedal assembly 14 at multiple positions within the usage position (e.g., Figures 1 to 5 (as shown in the best position) or positioned in the collapsed position (e.g.) Figures 6 to 10 (As shown in the best example).

[0074] Now for reference Figure 5 and Figure 6The first drive assembly 48 also includes a second threaded member 86, such as a lead screw, which is connected to the actuator 54 in a known manner via a flexible cable 88 or a flexible rod. It should be understood that the flexible cable 88 or flexible rod may be located within a housing, sheath, and / or cover, etc. The second threaded member 86 is an elongated member with a threaded portion adapted to engage with a gear 87 having an external thread, such that the second threaded member 86 and the gear 87 form a worm gear. In some embodiments, the second threaded member 86 is connected to a second output member, such as the shaft of the actuator 54, the second actuator, etc. In some embodiments, depending on the requirements of the pedal assembly 10, a suitable gear arrangement may be provided between the actuator 54 and the second threaded member 86 if necessary.

[0075] Gear 87 also includes a bore 104 for receiving a third threaded member 106. The third threaded member 106 may include a proximal end 110 and an opposing distal end 112. The distal end 112 may be L-shaped, having an opening for receiving a third shaft 84. That is, the third shaft 84 connects or couples the lower portion 82 of the ETC bracket 64 to the distal end 112 of the third threaded member 106. The third threaded member 106 may be positioned vertically to the pedal assembly (i.e., in the + / - Z direction), perpendicular to the second threaded member 86 oriented laterally to the pedal assembly (i.e., in the + / - Y direction). The third threaded member 106 includes a plurality of external threads 108. The bore 104 of gear 87 includes a plurality of internal threads complementary to the plurality of external threads 108 of the third threaded member 106. The second threaded member 86 rotates about the second rotation axis 98 in the direction indicated by arrow A5, causing the gear 87 to rotate about the third rotation axis 99 in the direction indicated by arrow A6, thereby moving the gear 87 along the third threaded member 106 in the direction perpendicular to the pedal assembly (i.e., in the + / -Z direction) in the direction indicated by arrow A11. In some embodiments, the gear 87 is molded from a suitable plastic material such as nylon. In other embodiments, the gear 87 is formed from a metal such as steel.

[0076] As discussed in more detail herein, activation of the second threaded member 86 causes gear 87 to rotate, which moves or rotates about or about the third threaded member 106 in the vertical direction of the pedal assembly (i.e., in the + / -Z direction). As a result, the second shaft 74 moves within the second elongated slot 70 in the direction indicated by arrow A7. As discussed in more detail herein, the third shaft 84 moves within the third pair of elongated slots 78 in the direction indicated by arrow A8.

[0077] In some embodiments, the second threaded member 86 is formed of a resin such as nylon. In other embodiments, the second threaded member 86 is formed of a metal such as steel. In some embodiments, a portion of the second threaded member 86 may be supported by a lower housing 18, which attaches the second threaded member 86 to the lower housing 18 such that it is positioned above the third pair of elongated slots 78 and below the second elongated slot 70 in the vertical direction of the pedal assembly (i.e., in the + / -Z direction). Furthermore, in some embodiments, the third threaded member 106 is formed of a resin such as nylon. In other embodiments, the third threaded member 106 is formed of a metal such as steel. In some embodiments, a portion of the third threaded member 106 may be supported by a lower housing 18, which attaches the third threaded member 106 to the lower housing 18 such that it is positioned after the third pair of elongated slots 78 in the longitudinal direction of the pedal assembly (i.e., in the + / -X direction).

[0078] Now for reference Figure 1 , Figure 6 , Figure 8 and Figure 13 In operation, to move the accelerator pedal assembly 12 to the retracted position, actuator 54 actuates the second threaded member 86 via flexible cable 88. The second threaded member 86 rotates the gear 87, thereby causing the gear 87 to move or rotate in the direction indicated by arrow A11 along the vertical direction of the pedal assembly (i.e., along the + / -Z direction). As a result, the second shaft 74 moves from the first end portion 81 to the second end portion 77 in the direction indicated by arrow A7 within the second elongated slot 70. Simultaneously, the third shaft 84 moves linearly from the first end portion 83b to the second end portion 83a in the vertical direction of the pedal assembly (i.e., the + / -Z direction) indicated by arrow A8 within the third pair of elongated slots 78.

[0079] The movement of the third shaft 84 raises the lower portion 82 of the ETC bracket 64, thereby moving or rotating the accelerator pedal assembly 12. This movement or rotation of the accelerator pedal assembly 12 causes the upper portion 72 of the ETC bracket 64, connected to the second shaft 74 guided by the second elongated slot 70, to move in the longitudinal direction of the pedal assembly (i.e., in the + / -X direction). This movement causes the accelerator pedal pad 68 to move toward the inner surface 92b of at least one receiving cavity 90. The second elongated slot 70 and the third pair of elongated slots 78 together guide the accelerator pedal pad 68 between the use position and the retracted position.

[0080] Still referencing Figure 1 , Figure 6 , Figure 8 and Figure 13In operation, to move the pedal assembly 14 to the retracted position, actuator 54 actuates the third threaded member 122 to move in the direction indicated by arrow A4, and actuates gear 124 to move in the direction indicated by arrow A12, causing the first threaded member 50 to move along shaft 56 in the direction indicated by arrow A10. This rotation or movement causes the first shaft 40 to move from the first end portion 41a to the second end portion 41b in the longitudinal direction of the pedal assembly (i.e., in the + / -X direction) in the direction of arrow A2. It should be understood that when actuator 54 rotates to place the pedal assembly 14 in the retracted position, the rotational movement of the first threaded member 50 also causes the support 53 and pivot portion 36 of the pedal assembly 14 to move away from the user-facing upper surface 20 in the longitudinal direction of the pedal assembly (i.e., in the +X direction), and causes the pedal pad 38 to rotate or move about the retracted shaft 120 toward the inner surface 92a of at least one receiving cavity 90 in the direction indicated by arrow A9. The elongated groove 46 guides the pedal arm 32 between the use position and the retracted position.

[0081] To return the accelerator pedal assembly 12 and / or pedal assembly 14 to a previous position (e.g., from the active position to the retracted position and / or from the retracted position to the active position), actuator 54 rotates to move the third threaded member 122 and / or the second threaded member 86 accordingly in the opposite direction to move the components in the opposite direction as described above. In some embodiments, the user or driver can position the pedal between the active position and the retracted position. In other embodiments, the electronic control unit (ECU) can determine whether the vehicle is in autonomous driving mode and activate actuator 54 to change the position of the pedal. For example, when the vehicle is set to autonomous driving mode, the ECU activates actuator 54 to move the pedal to the retracted position.

[0082] It should be understood that the ECU and pedal assembly 10 can further disable any pedal when in the retracted position and / or when the pedal should be in the retracted position, preventing the user or driver from sufficiently depressing the pedal pad to affect vehicle operation. For example, in some embodiments, the pedal assembly 14 requires a predetermined amount of depressurization before engaging the vehicle's braking system. Therefore, the ECU can intervene when the pedal assembly 14 is not in the retracted position but also not extended to a position sufficient to allow the required predetermined amount of pedal depressurization. In other words, the accelerator pedal assembly 12 is configured to control vehicle acceleration, and the electronic control unit disables acceleration control and / or other controls, such as braking, when the accelerator pedal assembly 12 and / or pedal assembly 14 are in the retracted position or should be in the retracted position.

[0083] Return to reference Figures 1 to 5 as well as Figures 8 to 12In some embodiments, the positions of the accelerator pedal assembly 12 and pedal assembly 14 in the use position can be adjusted by the vehicle operator between multiple adjustable positions in the use position along the longitudinal direction of the pedal assembly (i.e., along the + / -X direction) and along the vertical direction of the pedal assembly (i.e., along the + / -Z direction). Therefore, the first pair of elongated slots 46, the second elongated slot 70, and / or the third pair of elongated slots 78 can be used to provide the movement required for the accelerator pedal assembly 12 and pedal assembly 14 to any desired use position. That is, it should be understood that the accelerator pedal assembly 12 and pedal assembly 14 can be positioned at any desired position between these end positions (i.e., the terminations of the slots). In one embodiment, when the driver engages a control switch activating the actuator 54 to rotate in the desired direction, the positions of the accelerator pedal assembly 12 and pedal assembly 14 can be adjusted in the longitudinal direction of the pedal assembly (i.e., in the + / -X direction) and / or the vertical direction of the pedal assembly (i.e., in the + / -Z direction).

[0084] In other words, it should be understood that when the first shaft 40 is located at the first end portion 41a, the pedal assembly 14 is in the use position. Multiple use positions are defined by the first shaft 40 located between the first end portion 41a and the second end portion 41b. When the first shaft 40 is located at the second end portion 41b, the pedal assembly 14 is in the retracted position, wherein the pedal pad 38 is located in at least one receiving cavity 90.

[0085] When the third shaft 84 is located at the first end portion 83b and the second shaft 74 is located at the first end portion 81, the accelerator pedal assembly 12 is in the use position. Multiple use positions are defined by the third shaft 84 located between the first end portion 83b and the second end portion 83a and the second shaft 74 located between the first end portion 81 and the second end portion 77.

[0086] Therefore, a pedal assembly is disclosed, wherein each pedal is movable between multiple usable and retracted positions, wherein the pedals are unusable in the retracted position. Furthermore, in the retracted position, the pedals of the pedal assembly are positioned below the surface of the lower housing to allow unobstructed leg and foot space in the driver's floor during autonomous driving.

[0087] While specific embodiments have been shown and described herein, it should be understood that various other changes and modifications may be made without departing from the spirit and scope of the claimed subject matter. Furthermore, although various aspects of the claimed subject matter have been described herein, these aspects need not be used in combination. Therefore, the appended claims are intended to cover all such changes and modifications within the scope of the claimed subject matter.
