Detailed Implementation

[0020] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0021] like Figures 1 to 3 As shown, an exemplary embodiment of this disclosure provides a vehicle braking system, including a brake pedal arm 2 and a brake pedal 1 rotatably disposed on the brake pedal arm 2. The vehicle braking system also includes a lifting adjustment mechanism 3 and a horizontal adjustment mechanism 4, wherein the lifting adjustment mechanism 3 is used to drive the brake pedal arm 2 to move in the vehicle height direction, and the horizontal adjustment mechanism 4 is used to drive the brake pedal arm 2 to move in the vehicle longitudinal direction.

[0022] The driver's body type, such as height and build, affects the position of the steering wheel and its tilt angle relative to the vertical plane, as well as the position of the seat in the front-to-back direction and / or the position of the seat in the height direction of the vehicle. That is, the driver usually adjusts the position and angle of the seat and steering wheel according to his own body type. Different contact positions between the driver's foot and the brake pedal 1 can cause the brake pedal 1 to be too high or too low, too far forward or too far back, etc., affecting the driver's comfort when pressing the brake pedal 1, and even posing a safety hazard.

[0023] Furthermore, the position and angle of the brake pedal 1, under different dynamic driving habits of the driver, such as the force or frequency with which the driver presses the brake pedal 1, will also affect the driver's comfort when pressing the brake pedal 1. In addition, different driving scenarios may result in different vehicle speeds. For example, when driving at high speeds, a slightly lowered brake pedal 1 allows the driver to apply braking force more easily, while in city driving, a slightly higher brake pedal 1 is more conducive to frequent braking.

[0024] Therefore, the position of the brake pedal 1 in the vehicle height direction and the front-rear direction affects the driver's comfort and safety when braking.

[0025] To address this technical issue, the vehicle braking system provided in this disclosure, by setting up a lifting adjustment mechanism 3 and a horizontal adjustment mechanism 4, can adjust the position of the brake pedal arm 2 and thus the brake pedal 1 in the vehicle height direction and the longitudinal direction, thereby adjusting the brake pedal 1 to the most comfortable position for the driver, improving the comfort experience during driving, and avoiding operation delays caused by unsuitable pedal position, thus reducing safety hazards.

[0026] The drive mechanism can adaptively adjust the position of the brake pedal 1 based on driver posture information, brake pedal operation information, and vehicle motion status information. The driver can also actively adjust it according to their own needs, which will be described in detail later.

[0027] This disclosure does not limit the specific form of the lifting adjustment mechanism 3 and the horizontal adjustment mechanism 4. Any structure or method that can adjust the brake pedal arm 2 in the vehicle height direction and the front-rear direction can be applied to this disclosure.

[0028] In some possible implementations, such as Figure 1As shown, the lifting adjustment mechanism 3 includes a lifting adjustment motor 31 and a lifting adjustment bracket 32. The lifting adjustment bracket 32 ​​is movably mounted on the base 6. The brake pedal arm 2 is connected to the lifting adjustment bracket 32. The output end of the lifting adjustment motor 31 is provided with a lifting adjustment gear 33, and the lifting adjustment bracket 32 ​​is provided with a lifting adjustment rack 34 that meshes with the lifting adjustment gear 33. The base 6 can be fixedly mounted on the vehicle chassis. Utilizing the stable and high-precision characteristics of gear and rack transmission helps ensure the accuracy of lifting adjustment and adapts to the needs of drivers of different heights.

[0029] The base 6 may be equipped with a lifting slide rail 61 extending along the vehicle height direction. The lifting adjustment motor 31 is fixedly mounted on the lifting slide rail 61, and the lifting adjustment bracket 32 ​​is at least partially slidably mounted within the lifting slide rail 61. By providing the lifting slide rail 61 extending along the vehicle height direction on the base 6, the lifting and lowering movement of the lifting adjustment bracket 32 ​​can be guided, avoiding problems such as lateral deviation, swaying, or jamming during the movement of the lifting adjustment bracket 32, thus ensuring the reliability of the lifting adjustment.

[0030] In some possible implementations, refer to Figure 1 The horizontal adjustment mechanism 4 includes a horizontal adjustment motor 41 and a horizontal adjustment bracket 42. The horizontal adjustment motor 41 is fixedly mounted on the lifting adjustment bracket 32, and the horizontal adjustment bracket 42 is horizontally movable on the lifting adjustment bracket 32. The brake pedal arm 2 is connected to the horizontal adjustment bracket 42. The output end of the horizontal adjustment motor 41 is provided with a horizontal adjustment gear 43, and the horizontal adjustment bracket 42 is provided with a horizontal adjustment rack 44 that meshes with the horizontal adjustment gear 43.

[0031] The horizontal adjustment bracket 42 is horizontally movable on the lifting adjustment bracket 32. Combined with the gear and rack transmission driven by the horizontal adjustment motor 41, it can not only achieve precise adjustment of the brake pedal arm 2 along the front and rear direction of the vehicle, but also form a coordinated movement with the lifting adjustment bracket 32. That is, when the lifting adjustment mechanism 3 adjusts the height, the horizontal adjustment bracket 42 and the brake pedal arm 2 can rise and fall synchronously with the lifting adjustment bracket 32, without affecting the horizontal adjustment during the lifting process.

[0032] The horizontal adjustment bracket 42, the vertical adjustment bracket 32, and the base 6 are stacked sequentially in the vehicle height direction. This helps to make full use of the space in the vehicle height direction and avoids encroaching on the vehicle's lateral space, thereby optimizing the interior space layout.

[0033] In some possible implementations, the lifting and adjusting bracket 32 ​​includes a first vertical section 321 and a first horizontal section 322. For example, the lifting and adjusting bracket 32 ​​can be constructed in a T-shape. The first vertical section 321 is vertically and flexibly mounted on the base 6, and the lifting and adjusting rack 34 is mounted on the first vertical section 321. The lifting and adjusting bracket 32 ​​includes a horizontal slide rail 3221 that slides with the horizontal adjusting bracket 42, and the horizontal slide rail 3221 is mounted on the first horizontal section 322. Constructing the lifting and adjusting bracket 32 ​​to include the first vertical section 321 and the first horizontal section 322 allows for the integration of multiple functions into a single component, helping to reduce the number of parts used in the vehicle braking system. Specifically, the first vertical section 321 cooperates with the base 6 to achieve lifting and lowering, providing structural support for the lifting and adjusting mechanism 3; the first horizontal section 322, through the horizontal slide rail 3221, provides motion guidance for the horizontal movement of the horizontal adjusting bracket 42, preventing problems such as lateral deviation, swaying, or jamming during the movement of the horizontal adjusting bracket 42, and ensuring the reliability of the lifting and adjusting operation.

[0034] In some other possible embodiments, the horizontal adjustment bracket 42 includes a second vertical section 421 and a second horizontal section 422 fixedly connected to the second vertical section 421. The second horizontal section 422 is parallel to the first horizontal section 322 and slidably engages with a horizontal slide rail 3221. The second vertical section 421 is parallel to the first vertical section 321, with one end connected to the second horizontal section 422 and the other end connected to the brake pedal arm 2. The horizontal adjustment bracket 42, including the second vertical section 421 and the second horizontal section 422, further enhances the integration of the braking system components. The second horizontal section 422, being parallel to the first horizontal section 322 and slidably engaged with the horizontal slide rail 3221, provides stable guidance. The second vertical section 421, being parallel to the first vertical section 321 and with both ends connected to the second horizontal section 422 and the brake pedal arm 2 respectively, ensures stable force transmission and maintains structural harmony.

[0035] In some possible implementations, such as Figure 1As shown, the vehicle braking system may further include an angle adjustment mechanism 5, which drives the brake pedal 1 to tilt back and forth relative to a vertical plane. The angle adjustment mechanism 5 includes an angle adjustment motor 51, with an angle adjustment drive gear 52 at its output end. The brake pedal 1 is equipped with an angle adjustment driven gear 53 that meshes with the angle adjustment drive gear 52. The angle adjustment motor 51 drives the angle adjustment drive gear 52 to rotate coaxially around its output end, thereby driving the angle adjustment driven gear 53 to rotate circumferentially around the angle adjustment drive gear 52, thus adjusting the angle of the brake pedal 1. The angle adjustment drive gear 52 can be detachably mounted on the output end of the angle adjustment motor 51, or it can be integrally formed on the output end of the angle adjustment motor 51. Similarly, the angle adjustment driven gear 53 can be integrally formed on the brake pedal 1.

[0036] In some possible implementations, such as Figure 2 and Figure 3 As shown, the vehicle braking system also includes sensors 7, which include at least one of a steering wheel position sensor 71, a seat position sensor 72, a pedal pressure sensor 73, and a speed sensor 74. Sensors 7 are connected to the height adjustment mechanism 3, the leveling adjustment mechanism 4, and the angle adjustment mechanism 5. These sensors 7 can be used individually or in combination, and by integrating the monitoring results, the accuracy of control can be improved.

[0037] Based on the driver's different body types, dynamic driving habits, and vehicle speed, different driver posture information, brake pedal operation information, and vehicle motion status information will be generated. The lifting adjustment mechanism 3, the leveling adjustment mechanism 4, and the angle adjustment mechanism 5 can adaptively drive the brake pedal 1 to a comfortable position and angle for the driver based on this information, improving the driving experience and helping to avoid operation delays caused by uncomfortable pedal positions, thereby reducing safety hazards.

[0038] The adaptive function here can be understood as dynamically and in real-time adjusting the brake pedal 1 based on the information obtained by sensor 7. This adjustment of the brake pedal 1 can occur both during vehicle startup and during vehicle operation. Furthermore, the information obtained by sensor 7 is transmitted to the controller, which then transmits it to the lifting adjustment mechanism 3, the leveling adjustment mechanism 4, and the angle adjustment mechanism 5. The controller can be either a vehicle-wide controller or a separate controller configured for the actuation of the brake pedal 1; this disclosure does not impose any limitations on this.

[0039] The steering wheel position sensor 71 is used to acquire driver posture information, including the position of the steering wheel in the vehicle's longitudinal direction and / or the tilt angle of the steering wheel relative to a vertical plane. The steering wheel position sensor 71 can be, for example, an inertial measurement unit (IMU) or other attitude and tilt sensors. The steering wheel position sensor 71 can be mounted on the steering wheel or the vehicle chassis.

[0040] Driver posture information can also be obtained through the seat position sensor 72, including the seat's position in the fore-and-aft direction and / or the seat's position in the height direction of the vehicle. The seat position sensor 72 can be directly mounted on the seat or mounted on the vehicle chassis. The seat position sensor 72 can be a variety of displacement sensors, such as laser or cable sensors.

[0041] Operation of the brake pedal 1 may include the force applied to the brake pedal 1 and / or the frequency of applying the brake pedal 1. In some possible embodiments, a pedal pressure sensor 73 is used to acquire brake pedal operation information, including the force applied to the brake pedal 1 and / or the frequency of applying the brake pedal 1. The pedal pressure sensor 73 may be a mechanical switch or an electronic switch. The pedal pressure sensor 73 may be disposed on the brake pedal 1.

[0042] Vehicle motion state information can be, for example, the vehicle's speed or acceleration during travel. Vehicle acceleration can be used to monitor whether the vehicle is braking. In some possible implementations, a speed sensor 74 is used to acquire vehicle motion state information, including the vehicle's speed and / or acceleration. The speed sensor 74 can be located at the wheel, for example, as an inertial measurement unit.

[0043] In addition to using sensor 7 to adaptively adjust the position and angle of brake pedal 1, in some possible implementations, such as... Figure 3 As shown, the vehicle braking system also includes a central control panel 8, which is used for users to manually control the connection between the lifting adjustment mechanism 3, the leveling adjustment mechanism 4, and the angle adjustment mechanism 5. That is, the lifting adjustment mechanism 3, the leveling adjustment mechanism 4, and the angle adjustment mechanism 5 can also actively adjust the position and angle of the brake pedal 1 according to the driver's operation of the central control panel 8, or form a supplement to the adaptive adjustment.
