Description

Technical Field

[0001] This invention relates to the field of automotive technology, and more specifically, to a brake pedal assembly, a control method for the brake pedal assembly, and a vehicle. Background Technology

[0002] In some related technologies, during actual vehicle operation, due to significant differences in individual driver physiques, the positions of internal vehicle components (such as adjusting the seat) need to be adjusted for normal driving. Furthermore, the driver's posture varies depending on the driving mode. However, because the pedal assembly is set with a fixed leverage ratio based on braking performance, pedal feel, and booster parameters—meaning its position is fixed—it affects the driver's different driving needs.

[0003] In other related technologies, the adjustment of the pedal assembly position can be categorized into three types:

[0004] (1) Non-constant lever ratio adjustment. Non-constant lever ratio adjustment will change the lever ratio of the pedal assembly, which will cause changes in the pedal feel of the pedal assembly, affecting the driver's driving experience. Moreover, if a stepped adjustable method is used, the adjustment effect will be poor, and the development difficulty and manpower will be increased.

[0005] (2) Constant lever ratio adjustable pedal arm type. The constant lever ratio adjustable pedal arm type requires a large layout space and cannot achieve smooth switching between the accelerator pedal and the brake assembly.

[0006] (3) Pedal arm telescopic and multi-link pedal arm adjustment. The structure of the pedal arm telescopic and multi-link pedal arm adjustment is complex and occupies a large volume. Summary of the Invention

[0058] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0060] In the description of this invention, "first feature" and "second feature" may include one or more of the features, "multiple" means two or more, "above" or "below" the second feature may include the first and second features being in direct contact, or the first and second features being in contact through another feature between them, and "above," "over," and "on top" the second feature may include the first feature being directly above or diagonally above the second feature, or simply indicate that the first feature is at a higher horizontal level than the second feature.

[0061] The brake pedal assembly 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0062] Reference Figures 1-4 As shown, the brake pedal assembly 100 according to an embodiment of the present invention is used in a vehicle, and the brake pedal assembly 100 enables braking control of the vehicle to ensure driving safety. The brake pedal assembly 100 may include an adjustment component 20 and a pedal assembly 30.

[0063] Specifically, the adjustment assembly 20 includes an adjustment body 21 and a first rotating shaft 22. The first rotating shaft 22 is connected to the adjustment body 21, and the upper end of the pedal assembly 30 is rotatably connected to the first rotating shaft 22. The first rotating shaft 22 can serve as the working rotation axis of the braking assembly. When the driver depresses the pedal assembly 30, the pedal assembly 30 rotates around the first rotating shaft 22, enabling braking control of the vehicle, such as deceleration and stopping of the vehicle.

[0064] In addition, such as Figures 1-3 As shown, the adjustment assembly 20 also includes a pedal bracket 10 and a second rotating shaft 23. The second rotating shaft 23 is connected to the adjustment body 21 and is located below the first rotating shaft 22. The second rotating shaft 23 is rotatably connected to the pedal bracket 10. Therefore, the adjustment body 21 can rotate relative to the pedal bracket 10 via the second rotating shaft 23, allowing the adjustment body 21 to drive the pedal assembly 30 to move. This enables the pedal assembly 30 to be adjusted to adapt to different drivers' pedaling habits and legroom requirements, ensuring the comfort of the pedal assembly 30 and improving driving comfort and safety.

[0065] Compared to adjusting the pedal assembly 30 by having the first rotating shaft 22 and the second rotating shaft 23 coaxial, the first rotating shaft 22 and the second rotating shaft 23 of the present invention are not coaxial. This avoids the problem that the coaxial first rotating shaft 22 and the second rotating shaft 23 can easily lead to uneven switching between the accelerator pedal and the pedal assembly 30 after adjustment. It can also meet the adjustment of the pedal assembly 30 with a constant lever ratio, reduce the arrangement space, and at the same time, there is no need to make major changes to the pedal assembly 30. That is, the pedal assembly 30 can be a standard-sized pedal assembly 30, which can reduce the volume occupied and is conducive to platformization.

[0066] According to an embodiment of the present invention, the brake pedal assembly 100 is connected to the adjustment body 21 via a first rotating shaft 22 and a second rotating shaft 23. The second rotating shaft 23 is located below the first rotating shaft 22 and is rotatably connected to the pedal bracket 10. The upper end of the pedal assembly 30 is rotatably connected to the first rotating shaft 22, so that the pedal assembly 30 can be adjusted by the adjustment body 21 to adapt to the different driving habits and leg space requirements of different drivers, ensuring the comfort of the pedal assembly 30. It can also avoid the problem that the coaxiality of the first rotating shaft 22 and the second rotating shaft 23 can easily lead to uneven switching between the accelerator pedal and the pedal assembly 30 after adjustment, satisfying the adjustment of the pedal assembly 30 with a constant lever ratio. At the same time, it occupies a small volume, which can reduce the layout space and is conducive to platformization.

[0067] In some embodiments of the present invention, such as Figure 1 As shown, the brake pedal assembly 100 also includes a drive mechanism 40, which is connected to the pedal bracket 10. The drive mechanism 40 can drive the adjustment component 20 to rotate around the second rotating shaft 23, thereby realizing the automatic adjustment function of the brake pedal assembly 100, making adjustment more convenient, improving driving convenience, and realizing intelligent control.

[0068] According to some embodiments of the present invention, such as Figure 1As shown, at least a portion of the second rotating shaft 23 is formed as a worm gear. The drive mechanism 40 includes a drive motor 41 and a worm 42. The drive motor 41 is connected to the pedal bracket 10 to fix the drive motor 41. The worm 42 is connected to the output shaft of the drive motor 41 and engages with the worm gear. Thus, the drive motor 41 can drive the worm 42 to rotate through the output shaft, enabling stepless adjustment of the worm gear 42 to meet different driving needs of the driver, ensuring smoother and more precise adjustment. Furthermore, the worm gear 42 engagement has self-locking properties, preventing the pedal assembly 30 from rotating around the second rotating shaft 23 due to other forces, thus improving the stability and safety of the brake pedal assembly 100. At the same time, it ensures a compact structure for the brake pedal assembly 100, reducing space occupation.

[0069] In some embodiments of the present invention, such as Figures 1-3 As shown, the adjustment body 21 includes a first adjustment plate 211 and a second adjustment plate 212, the first adjustment plate 211 and the second adjustment plate 212 being aligned along the thickness direction of the first adjustment plate 211 (e.g., Figure 1 The pedal assembly 30 is positioned between the first adjusting plate 211 and the second adjusting plate 212, and the first rotating shaft 22 is positioned along its length (e.g., in the left-right direction). Figure 1 The first adjusting plate 211 and the second adjusting plate 212 are connected to the two ends of the second rotating shaft 23 (in the left and right directions shown in the figure), respectively. The second rotating shaft 23 is connected to the first adjusting plate 211 to ensure that the first rotating shaft 22 and the second rotating shaft 23 are reliably connected to the adjusting body 21. This provides stable support for the pedal assembly 30, ensuring the stability and reliability of the pedal assembly 30 during the adjustment process. The adjusting body 21 has a simple structure, is easy to process and manufacture, and can ensure a compact structure, which is conducive to achieving lightweight design.

[0070] According to some embodiments of the present invention, such as Figure 1 As shown, the adjustment assembly 20 also includes a third rotating shaft 24, which is located on the side of the second adjustment plate 212 away from the pedal assembly 30. The length direction of the third rotating shaft 24 (e.g.) Figure 1 One end of the third rotating shaft 24 (in the left-right direction shown in the figure) is connected to the second adjusting plate 212, and the other end of the third rotating shaft 24 in the length direction is rotatably connected to the pedal bracket 10. The third rotating shaft 24 is coaxial with the second rotating shaft 23. The third rotating shaft 24 can be connected to the second adjusting plate 212 and the pedal bracket 10, which adds a support point to the adjusting assembly 20, ensuring that the second adjusting plate 212 is fixed and reliable, thereby further ensuring the fixed reliability of the adjusting body 21 and improving the stability and load-bearing capacity of the adjusting assembly 20.

[0071] In some embodiments of the present invention, such as Figures 1-4As shown, the pedal assembly 30 is provided with a limiting shaft 31, and the adjusting body 21 is provided with an arc-shaped groove 213 centered on the axis of the first rotating shaft 22. The limiting shaft 31 extends into the arc-shaped groove 213. Thus, when the brake pedal assembly 100 brakes, that is, when the pedal assembly 30 rotates around the first rotating shaft 22, the adjusting body 21 can limit the rotation of the pedal assembly 30 through the cooperation of the limiting shaft 31 and the arc-shaped groove 213, preventing the pedal assembly 30 from rotating excessively or deviating from the predetermined position, which helps to improve the stability and reliability of the brake pedal assembly 100.

[0072] In some embodiments where the adjusting body 21 includes a first adjusting plate 211 and a second adjusting plate 212, such as Figure 1 As shown, the pedal assembly 30 in the width direction (e.g.) Figure 1 Limiting shafts 31 are provided on both sides of the pedal assembly 30 (shown in the left and right directions). The first adjusting plate 211 and the second adjusting plate 212 are each provided with an arc-shaped groove 213 centered on the axis of the first rotating shaft 22. The two limiting shafts 31 extend into the arc-shaped groove 213 on the same side. Through the cooperation of the two limiting shafts 31 and the two arc-shaped grooves 213, the two sides of the width direction of the pedal assembly 30 can be limited to prevent the pedal assembly 30 from tilting and ensure the stability and reliability of the brake pedal assembly 100.

[0073] According to some embodiments of the present invention, such as Figures 1-4 As shown, the brake pedal assembly 100 also includes a booster, which includes a ball cage 51 and a booster rod. One end of the booster rod is rotatably connected to the ball cage 51, and the ball cage 51 is connected to the pedal assembly 30. Thus, when the brake pedal assembly 100 is engaged, the pedal assembly 30 is pressed down, the adjusting component 20 remains stationary, and the pedal assembly 30 rotates around the first pivot 22 (e.g., counterclockwise). The pedal assembly 30 and the ball cage 51 press against each other and push the ball cage 51, causing the ball cage 51 to push the booster rod to move, thus enabling the brake pedal assembly 100 to function normally. The booster provides additional assistance, making the braking process easier and faster, effectively reducing the physical exertion of the driver when pressing the brake assembly. When the pedal assembly 30 is released, the booster rod transmits force to the ball cage 51, causing the pedal assembly 30 to rotate in the opposite direction (e.g., clockwise) around the first pivot 22 under the driving action of the ball cage 51, thus resetting the pedal assembly 30.

[0074] In addition, such as Figures 1-4As shown, the ball cage 51 is rotatably connected to the pedal assembly 30, and the ball cage 51 is located below the first rotating shaft 22. Thus, when the pedal assembly 30 is adjusted, that is, when the adjustment body 21 rotates relative to the pedal bracket 10 through the second rotating shaft 23, the pedal assembly 30 can rotate relative to the ball cage 51, thereby ensuring that the position of the ball cage 51 does not change with the adjustment of the pedal assembly 30, ensuring that the assist rod remains in the normal swing position and meets the swing position requirements of the assist rod.

[0075] In some embodiments of the present invention, such as Figures 2-4 As shown, the pedal assembly 30 is provided with a slide groove 32. The inner wall of the slide groove 32 is an arc-shaped surface. The outer peripheral wall of the ball cage 51 fits against the inner wall of the slide groove 32, and the ball cage 51 can rotate relative to the inner wall of the slide groove 32. This enables the ball cage 51 to be rotatably connected to the pedal assembly 30, which facilitates the rotation of the pedal assembly 30 relative to the ball cage 51. This makes the rotation of the pedal assembly 30 relative to the ball cage 51 smooth and stable. The structure is simple, easy to process and manufacture, and helps to reduce production costs.

[0076] According to some embodiments of the present invention, such as Figure 1 and Figure 4 As shown, the pedal assembly 30 includes a pedal arm 301 and a pedal pad 302. The upper end of the pedal arm 301 is rotatably connected to the first rotating shaft 22, and the pedal pad 302 is connected to the lower end of the pedal arm 301. The pedal pad 302 is the direct contact surface between the driver and the pedal arm 301. The pedal pad 302 can provide a comfortable pedaling feel and good friction. The pedal arm 301 can connect the pedal pad 302 to the adjustment assembly 20, which facilitates the adjustment of the position of the pedal pad 302. At the same time, the force of the driver pressing the pedal pad 302 can be transmitted to the pedal arm 301, and the pedal arm 301 can realize the braking control of the vehicle.

[0077] Furthermore, a pressure sensor is installed on the pedal pad 302. This sensor can detect whether there is pressure on the pedal pad 302 or the magnitude of the pressure, providing accurate feedback signals and enabling intelligent operation. For example, when adjusting the pedal assembly 30, the pressure sensor can detect whether the driver is pressing the pedal pad 302, prompting the driver to be alerted and preventing the pedal assembly 30 from pressing against the foot, thus improving the safety level of the brake pedal assembly 100.

[0078] The control method of the brake pedal assembly 100 according to an embodiment of the present invention, wherein the brake pedal assembly 100 is the brake pedal assembly 100 according to an embodiment of the present invention.

[0079] like Figure 5 and Figure 7 As shown, the control methods include:

[0080] Confirm that the vehicle is powered on;

[0081] Obtaining the angle parameters of the pedal assembly 30 facilitates subsequent determination of whether the pedal assembly 30 is within the driver's comfortable angle range;

[0082] The angle of the pedal assembly 30 is determined to be an uncomfortable angle. For example, an uncomfortable angle may be that the angle of the pedal assembly 30 does not meet the driver's need for a comfortable operating position or that the driving mode selected in the vehicle's control system is different from the current angle of the pedal assembly 30.

[0083] The control adjustment component 20 rotates around the second pivot 23 until the angle of the pedal assembly 30 reaches a comfortable target angle parameter. For example, the adjustment component 20 can be driven to rotate around the second pivot 23 by the drive motor 41. Thus, before the driver starts driving, the pedal assembly 30 can be adjusted to adapt to different pedaling habits and legroom requirements, ensuring the pedal assembly 30's pedaling comfort and improving driving comfort and safety.

[0084] In some embodiments, when the drive motor 41 drives the adjustment component 20 to rotate around the second rotating shaft 23, the target angle parameter can be the rotation angle parameter of the drive motor 41 set in different driving modes, or the target angle parameter can be the rotation angle parameter of the dedicated drive motor 41 set by an individual. The angle of the pedal component 30 is in an uncomfortable angle because the current rotation angle of the drive motor 41 is different from the target angle parameter. By controlling the rotation angle of the drive motor 41, the angle of the pedal component 30 can reach the target angle parameter, making the adjustment simpler and more convenient, and facilitating stepless adjustment.

[0085] Since the brake pedal assembly 100 according to the embodiments of the present invention has the above-mentioned beneficial technical effects, the control method of the brake pedal assembly 100 according to the embodiments of the present invention, through the first rotating shaft 22 and the second rotating shaft 23 both connected to the adjustment body 21, the second rotating shaft 23 is located below the first rotating shaft 22, the second rotating shaft 23 is rotatably connected to the pedal bracket 10, and the upper end of the pedal assembly 30 is rotatably connected to the first rotating shaft 22, so that the pedal assembly 30 can be adjusted by the adjustment body 21 to adapt to the different driving habits and leg space requirements, ensuring the comfort of the pedal assembly 30, and avoiding the problem that the coaxiality of the first rotating shaft 22 and the second rotating shaft 23 can easily lead to uneven switching between the accelerator pedal and the pedal assembly 30 after adjustment, satisfying the adjustment of the pedal assembly 30 with a constant lever ratio, while occupying a small volume, reducing the layout space, and facilitating platformization.

[0086] In some embodiments of the present invention, such as Figure 6 As shown, the control method for the brake pedal assembly 100 also includes:

[0087] Confirm that the vehicle is powered off;

[0088] The control adjustment component 20 rotates around the second rotating shaft 23 to move the lower end of the pedal assembly 30 downward until the pedal assembly 30 reaches its lower limit position. For example, the adjustment component 20 can be driven to rotate around the second rotating shaft 23 by the drive motor 41. Thus, after the vehicle is powered off, the downward movement of the lower end of the pedal assembly 30 can meet the need for obstacle avoidance, prevent the pedal assembly 30 from occupying too much space, facilitate the driver's entry and exit from the vehicle or other operations, and help ensure the intelligence of the brake pedal assembly 100.

[0089] According to some embodiments of the present invention, such as Figures 5-7 As shown, before the control adjustment assembly 20 rotates around the second rotating shaft 23, it also includes:

[0090] Determine whether the pedal assembly 30 is under pressure, for example, by detecting whether it is under pressure using a pressure sensor on the pedal pad 302;

[0091] If so, issue a warning not to step on the pedal assembly 30 until the pressure on the pedal assembly 30 is released;

[0092] If not, the adjustment component 20 is controlled to rotate around the second rotating shaft 23. For example, the adjustment component 20 is driven to rotate around the second rotating shaft 23 by the drive motor 41 to achieve the adjustment requirements of the pedal assembly 30.

[0093] Therefore, before adjusting the pedal assembly 30, the driver is reminded not to step on the pedal assembly 30 to avoid squeezing or jamming the driver's foot during the adjustment process, thus avoiding safety hazards and improving the safety level of the brake pedal assembly 100.

[0094] In some embodiments where the drive motor 41 drives the adjustment assembly 20 to rotate around the second rotating shaft 23, when the pressure sensor on the pedal pad 302 detects pressure, the pressure sensor sends a signal to the vehicle's control system. The drive motor 41 can receive the control signal from the control system, causing the drive motor 41 to actuate and fulfill the control requirements for the drive motor 41.

[0095] In some embodiments of the present invention, the acquisition of the target angle parameter includes self-adjustment, which can determine a comfortable angle of the pedal assembly 30 according to the driver's actual pedaling habits to meet the required driving requirements; or, the acquisition of the target angle parameter includes direct input, whereby the target angle parameter is set during vehicle production for easy selection by the driver. Thus, the adjustment of the pedal assembly 30 becomes flexible and personalized, making the control of the brake pedal assembly 100 more in line with the driver's needs.

[0096] According to some embodiments of the present invention, such as Figure 8As shown, when acquiring the target angle parameters includes self-adjustment, the control method includes:

[0097] Determine whether the pedal assembly 30 is under pressure, for example, by detecting whether it is under pressure using a pressure sensor on the pedal pad 302;

[0098] If so, the control adjustment component 20 rotates around the second rotating shaft 23 to move the lower end of the pedal assembly 30 downward. For example, the drive motor 41 drives the adjustment component 20 to rotate around the second rotating shaft 23 until the pedal assembly 30 reaches the lower limit position, that is, the driver's foot continuously and lightly presses the pedal assembly 30, so that the pedal assembly 30 reaches the lower limit position, and the target angle parameter is stored; or, after the pressure on the pedal assembly 30 is removed, that is, when the driver's foot reaches a comfortable human-machine posture and does not press the pedal assembly 30, the control adjustment component 20 rotates around the second rotating shaft 23 to move the lower end of the pedal assembly 30 upward until the pedal assembly 30 is subjected to pressure again, that is, the position where the driver's foot presses the pedal assembly 30, and the target angle parameter is stored.

[0099] If not, the control adjustment component 20 rotates around the second pivot 23 to move the lower end of the pedal assembly 30 upward until the pedal assembly 30 reaches the upper limit position, that is, the driver's foot is not pressing the pedal assembly 30, so that the pedal assembly 30 reaches the upper limit position and stores the target angle parameter; or, the pedal assembly 30 is in a position where pressure is applied, that is, the driver's foot is in a comfortable human-machine posture, the pedal assembly 30 is adjusted to contact the driver's foot, and the target angle parameter is stored.

[0100] Therefore, by obtaining the target angle parameters in the above-mentioned way, the target angle parameters of the driver in a comfortable human-machine posture can be accurately obtained, which makes it easier to adjust the pedal assembly 30 to a comfortable angle, thus improving driving comfort and convenience.

[0101] The vehicle according to an embodiment of the present invention includes a brake pedal assembly 100 according to an embodiment of the present invention. Since the brake pedal assembly 100 according to an embodiment of the present invention has the aforementioned beneficial technical effects, the vehicle according to an embodiment of the present invention, with both a first rotating shaft 22 and a second rotating shaft 23 connected to an adjustment body 21, the second rotating shaft 23 located below the first rotating shaft 22, and rotatably connected to a pedal bracket 10, and the upper end of the pedal assembly 30 rotatably connected to the first rotating shaft 22, allows the pedal assembly 30 to be adjusted via the adjustment body 21 to adapt to different drivers' pedaling habits and legroom requirements, ensuring the comfort of the pedal assembly 30. It also avoids the problem of uneven transition between the accelerator pedal and the pedal assembly 30 after adjustment due to the coaxiality of the first rotating shaft 22 and the second rotating shaft 23, satisfying the adjustment of the pedal assembly 30 with a constant lever ratio, while occupying a small volume, reducing layout space, and facilitating platformization.

[0102] In some embodiments, the vehicle includes a front bulkhead, and the pedal bracket 10 is fixed to the front bulkhead to ensure that the pedal bracket 10 is reliably fixed on the vehicle, facilitates assembly, and ensures a compact structure.

[0103] The brake pedal assembly 100 according to embodiments of the present invention, along with other components and operations of the vehicle, are known to those skilled in the art and will not be described in detail here.
