Description

Technical Field

[0001] The present invention relates to the field of automobile technology, and more specifically, to a brake pedal assembly, a control method for the brake pedal assembly, and a vehicle. Background Art

[0002] In some related technologies, in actual driving of a vehicle, due to the large differences in the body size of individual drivers, in order to drive the vehicle normally, it is necessary to adjust the position of the internal device of the vehicle (for example, adjust the seat), and the driver's human-machine posture will also be different in different driving modes. However, since the pedal assembly is set with a fixed lever ratio according to the braking performance, pedal feel, booster parameters, etc., that is, the position of the pedal assembly is fixed, which affects the different driving needs of the driver.

[0003] In other related technologies, the adjustment method of the pedal assembly position has the following three situations:

[0004] (1) Non-constant lever ratio adjustment. The non-constant lever ratio adjustment will change the lever ratio of the pedal assembly, which will cause the pedal feel of the pedal assembly to change, affecting the driver's driving experience. If a step-by-step adjustment method is used, the adjustment effect is poor and the development difficulty and manpower are increased.

[0005] (2) Constant lever ratio pedal arm type. The constant lever ratio pedal arm type requires a larger layout space and cannot achieve smooth conversion of the accelerator pedal and brake assembly.

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

[0062] Reference Figure 1-Figure 4 As shown, the brake pedal assembly 100 according to the embodiment of the present invention is used for a vehicle, and the brake pedal assembly 100 can be used to control the braking of the vehicle to ensure driving safety. The brake pedal assembly 100 may include: an adjustment assembly 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, the upper end of the pedal assembly 30 is rotatably connected to the first rotating shaft 22, and the first rotating shaft 22 can be formed as a working rotating shaft of the brake assembly. When the driver steps on the pedal assembly 30, the pedal assembly 30 rotates around the first rotating shaft 22, and the braking control of the vehicle can be achieved, such as deceleration and parking of the vehicle.

[0064] In addition, if Figure 1-Figure 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, the second rotating shaft 23 is located below the first rotating shaft 22, and 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 through the second rotating shaft 23, so that the adjustment body 21 can drive the pedal assembly 30 to move, so that the pedal assembly 30 can be adjusted to adapt to the pedaling habits and leg space requirements of different drivers, ensure the comfort of the pedal assembly 30, and help improve driving comfort and safety.

[0065] Compared with adjusting the pedal assembly 30 by coaxially adjusting the first rotating shaft 22 and the second rotating shaft 23, the first rotating shaft 22 and the second rotating shaft 23 of the present invention are not coaxial, which avoids the problem of uneven conversion of the accelerator pedal and the pedal assembly 30 after adjustment caused by the coaxiality of the first rotating shaft 22 and the second rotating shaft 23, and can meet the adjustment of the pedal assembly 30 with a constant lever ratio, reducing the layout space. At the same time, there is no need to make major changes to the pedal assembly 30, that is, the pedal assembly 30 can adopt a pedal assembly 30 of ordinary size, which can reduce the occupied volume and is conducive to platformization.

[0066] According to the brake pedal assembly 100 of the embodiment of the present invention, the first rotating shaft 22 and the second rotating shaft 23 are 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. 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 through the adjustment body 21 to adapt to the pedaling habits and leg space requirements of different drivers, ensure the comfort of the pedal assembly 30, and avoid the problem of uneven conversion of 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, so as to meet the adjustment of the pedal assembly 30 with a constant lever ratio, while occupying a small volume, being able to reduce the layout space, and being conducive to platformization.

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

[0068] According to some embodiments of the present invention, Figure 1As shown, at least part of the second rotating shaft 23 is formed as a worm gear, and the driving mechanism 40 includes a driving motor 41 and a worm 42. The driving motor 41 is connected to the pedal bracket 10 to fix the driving motor 41. The worm 42 is connected to the output shaft of the driving motor 41, and the worm 42 cooperates with the worm gear. Therefore, the driving motor 41 can drive the worm 42 to rotate through the output shaft, so that the worm gear 42 cooperates to achieve stepless adjustment, which is convenient for meeting different driving needs of the driver and ensures that the adjustment is more stable and accurate. The worm gear 42 cooperates with the self-locking property, which can prevent the pedal assembly 30 from rotating around the second rotating shaft 23 due to other forces, thereby improving the stability and safety of the brake pedal assembly 100. At the same time, it ensures that the structure of the brake pedal assembly 100 is compact, which is conducive to reducing the occupied space.

[0069] In some embodiments of the present invention, Figure 1-Figure 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 are arranged along the thickness direction of the first adjustment plate 211 (for example, Figure 1 The pedal assembly 30 is located between the first adjustment plate 211 and the second adjustment plate 212. The length direction of the first rotating shaft 22 (for example Figure 1 The two ends of the pedal assembly 30 (in the left and right directions shown in the figure) are respectively connected to the first adjustment plate 211 and the second adjustment plate 212, and the second rotating shaft 23 is connected to the first adjustment plate 211, ensuring that the first rotating shaft 22 and the second rotating shaft 23 are reliably connected to the adjustment body 21, thereby providing stable support for the pedal assembly 30, ensuring the stability and reliability of the pedal assembly 30 during the adjustment process, and the structure of the adjustment body 21 is simple, which is convenient for processing and manufacturing, and at the same time can ensure that the structure is compact, which is conducive to achieving lightweight design.

[0070] According to some embodiments of the present invention, Figure 1 As shown, the adjustment assembly 20 further includes a third shaft 24, which is located on a side of the second adjustment plate 212 away from the pedal assembly 30. The length direction of the third shaft 24 (eg Figure 1 One end of the third rotating shaft 24 (in the left and right directions 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 and ensures that the second adjusting plate 212 is reliably fixed, thereby further ensuring that the adjusting body 21 is reliably fixed, and improving the stability and carrying capacity of the adjusting assembly 20.

[0071] In some embodiments of the present invention, Figure 1-Figure 4As shown, a limiting shaft 31 is provided on the pedal assembly 30, and an arc groove 213 with the axis of the first rotating shaft 22 as the center is provided on the adjusting body 21, and the limiting shaft 31 extends into the arc groove 213. Therefore, when the brake pedal assembly 100 is braking, 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 groove 213, so as to prevent the pedal assembly 30 from excessively rotating or deviating from the predetermined position, which is conducive to improving the stability and reliability of the brake pedal assembly 100.

[0072] In some embodiments, the adjustment body 21 includes a first adjustment plate 211 and a second adjustment plate 212. Figure 1 As shown, the width direction (eg Figure 1 A limit shaft 31 is provided on both sides of the first adjustment plate 211 and the second adjustment plate 212, and an arc groove 213 with the axis of the first rotating shaft 22 as the center of the circle is provided. The two limit shafts 31 are respectively extended into the arc grooves 213 located on the same side. Through the cooperation of the two limit shafts 31 and the two arc grooves 213, the two sides of the width direction of the pedal assembly 30 can be limited to avoid the pedal assembly 30 from tilting during movement, thereby ensuring the stability and reliability of the brake pedal assembly 100.

[0073] According to some embodiments of the present invention, Figure 1-Figure 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. Therefore, when the brake pedal assembly 100 is braked, the pedal assembly 30 is stepped on, the adjustment assembly 20 remains stationary, the pedal assembly 30 rotates around the first rotating shaft 22 (for example, counterclockwise), the pedal assembly 30 and the ball cage 51 are pressed against each other and push the ball cage 51, so that the ball cage 51 pushes the booster rod to move, and the normal operation of the brake pedal assembly 100 is achieved. The booster can provide additional assistance, making the braking process easier and faster, and effectively reducing the physical exertion of the driver when stepping on the brake assembly; when the pedal assembly 30 is released, the booster rod transmits force to the ball cage 51, so that the pedal assembly 30 rotates in the opposite direction (for example, clockwise) around the first rotating shaft 22 under the driving action of the ball cage 51, and the pedal assembly 30 is reset.

[0074] In addition, if Figure 1-Figure 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. Therefore, 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 ball cage 51 does not change position with the adjustment of the pedal assembly 30, ensuring that the power-assisting rod remains in a normal swing position, and meeting the swing position requirements of the power-assisting rod.

[0075] In some embodiments of the present invention, Figure 2-Figure 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 is in contact with the inner wall of the slide groove 32, and the ball cage 51 is rotatable relative to the inner wall of the slide groove 32, so that the ball cage 51 and the pedal assembly 30 can be rotatably connected, which facilitates the rotation of the pedal assembly 30 relative to the ball cage 51, so that the pedal assembly 30 can rotate relative to the ball cage 51 smoothly and stably, and the structure is simple, which is convenient for processing and manufacturing, and is conducive to reducing production costs.

[0076] According to some embodiments of the present invention, 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 a direct contact surface between the driver and the pedal arm 301. The pedal pad 302 can provide a comfortable pedaling feeling and good friction. The pedal arm 301 can be used to connect the pedal pad 302 to the adjustment assembly 20, which is convenient for adjusting the position of the pedal pad 302. At the same time, the force of the driver stepping on the pedal pad 302 can be transmitted to the pedal arm 301, and the braking control of the vehicle can be achieved through the pedal arm 301.

[0077] In addition, a pressure sensor is provided on the pedal pad 302, and the pressure sensor can detect whether there is pressure on the pedal pad 302 or the size of the pressure on the pedal pad 302, so as to provide an accurate feedback signal and realize intelligence. For example, when adjusting the pedal assembly 30, the pressure sensor can detect whether the driver steps on the pedal pad 302, so as to remind the driver and prevent the pedal assembly 30 from squeezing the foot, which is beneficial to improving the safety level of the brake pedal assembly 100.

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

[0079] like Figure 5 and Figure 7 As shown, the control method includes:

[0080] Make sure the vehicle is powered on;

[0081] Obtaining angle parameters of the pedal assembly 30 to facilitate subsequent determination of whether the pedal assembly 30 is within a comfortable angle range for the driver;

[0082] Determining that the angle of the pedal assembly 30 is at a non-comfortable angle, for example, the non-comfortable angle may be that the angle of the pedal assembly 30 cannot meet the requirements of the driver's comfortable operating position or the driving mode selected in the control system of the vehicle is different from the current angle of the pedal assembly 30;

[0083] The adjustment assembly 20 is controlled to rotate around the second rotation axis 23 until the angle of the pedal assembly 30 reaches a comfortable target angle parameter, for example, the adjustment assembly 20 is driven to rotate around the second rotation axis 23 by the driving motor 41. Thus, before the driver drives, the pedal assembly 30 can be adjusted to adapt to different pedaling habits and leg space requirements, thereby ensuring the pedaling comfort of the pedal assembly 30, which is conducive to improving driving comfort and safety.

[0084] In some embodiments, when the drive motor 41 drives the adjustment assembly 20 to rotate around the second rotation axis 23, the target angle parameter can be the rotation angle parameter of the drive motor 41 set under different driving modes, or the target angle parameter can be a dedicated rotation angle parameter of the drive motor 41 set by an individual. The angle of the pedal assembly 30 is at a non-comfortable 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 assembly 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 embodiment of the present invention has the above-mentioned beneficial technical effects, the control method of the brake pedal assembly 100 according to the embodiment of the present invention is that the first rotating shaft 22 and the second rotating shaft 23 are 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 through the adjustment body 21 to adapt to the pedaling habits and leg space requirements of different drivers, ensure the comfort of the pedal assembly 30, and avoid the problem of uneven conversion of 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, meet the adjustment of the pedal assembly 30 with a constant lever ratio, and at the same time occupy a small volume, can reduce the layout space, and is conducive to platformization.

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

[0087] Make sure the vehicle is powered off;

[0088] The adjusting assembly 20 is controlled to rotate around the second rotating shaft 23 to move the lower end of the pedal assembly 30 downward until the pedal assembly 30 reaches the lower limit position, for example, the adjusting assembly 20 is driven to rotate around the second rotating shaft 23 by the driving motor 41. Therefore, after the vehicle is powered off, the lower end of the pedal assembly 30 moves downward to meet the avoidance requirement, avoiding the pedal assembly 30 from occupying a large space, facilitating the driver to enter and exit the vehicle or perform other operations, which is conducive to ensuring the intelligence of the brake pedal assembly 100.

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

[0090] Determining whether the pedal assembly 30 is under pressure, for example, by detecting whether pressure is applied via a pressure sensor on the pedal pad 302;

[0091] If yes, a message is sent to remind the user not to step on the pedal assembly 30 until the pressure of the pedal assembly 30 disappears;

[0092] If not, the adjusting assembly 20 is controlled to rotate around the second rotating shaft 23 , for example, the adjusting assembly 20 is driven to rotate around the second rotating shaft 23 by the driving motor 41 to achieve the adjustment demand on the pedal assembly 30 .

[0093] Therefore, before the pedal assembly 30 is adjusted, the driver is reminded not to step on the pedal assembly 30 to avoid squeezing or jamming the driver's feet during the adjustment of the pedal assembly 30, thereby avoiding safety hazards and helping to improve 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 control system of the vehicle, and the drive motor 41 is able to receive the control signal of the control system, so that the drive motor 41 is actuated to realize the control requirements of 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 the comfortable angle of the pedal assembly 30 according to the actual pedaling habits of the driver to meet the required driving requirements; or, the acquisition of the target angle parameter includes direct input, and the target angle parameter is set when the vehicle is produced, which is convenient for the driver to choose. In this way, the adjustment of the pedal assembly 30 can be flexible and personalized, so that the control of the brake pedal assembly 100 can better meet the needs of the driver.

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

[0097] Determining whether the pedal assembly 30 is subjected to pressure, for example, by detecting whether the pedal assembly 30 is subjected to pressure through a pressure sensor on the pedal pad 302;

[0098] If so, the adjusting assembly 20 is controlled to rotate about the second rotating shaft 23 so that the lower end of the pedal assembly 30 moves downward, for example, the adjusting assembly 20 is driven to rotate about the second rotating shaft 23 by the driving motor 41 until the pedal assembly 30 reaches the lower limit position, that is, the driver's foot continues to lightly step on 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 disappears, that is, when the driver's foot reaches a comfortable human-machine posture and does not step on the pedal assembly 30, the adjusting assembly 20 is controlled to rotate about the second rotating shaft 23 so that the lower end of the pedal assembly 30 moves upward until the pedal assembly 30 is under pressure again, that is, the position where the driver's foot steps on the pedal assembly 30, and the target angle parameter is stored;

[0099] If not, the control adjustment assembly 20 is rotated about the second rotating shaft 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 does not step on the pedal assembly 30, so that the pedal assembly 30 reaches the upper limit position, and the target angle parameter is stored; 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, and the pedal assembly 30 is adjusted to contact the driver's foot, and the target angle parameter is stored.

[0100] Therefore, by the above-mentioned method of obtaining the target angle parameters, the target angle parameters of the driver in a comfortable human-machine posture can be accurately obtained, which facilitates the pedal assembly 30 to be adjusted to a comfortable angle, which is beneficial to improving driving comfort and convenience.
