[0052] The pedal assembly and the driving assembly are respectively connected to the elastic assembly;

[0053] The drive assembly controls the elastic assembly to deform, so as to adjust the feedback force transmitted to the pedal assembly by the elastic assembly when the pedal assembly drives the elastic assembly to extend and retract. In an embodiment of the present application, specifically, the pedal assembly can be connected to one end of the elastic assembly, and the drive assembly can be connected to the other end of the elastic assembly. When the pedal assembly is subjected to the same degree of stepping, the pedal assembly drives one end of the elastic assembly to move, and the elastic assembly is deformed. At this time, the drive assembly adjusts the other end of the elastic assembly to extend and retract, so that the elastic assembly can generate the required degree of feedback force, so that the drive assembly can be set to generate different moving distances of the other end of the elastic assembly for different vehicle models, so as to generate different extension amounts, thereby generating different feedback forces transmitted to the pedal assembly. Thus, it can be applied to different vehicle models to give users different degrees of pedal feel, so that the elastic assembly can be universal for different vehicle models, thereby improving the compatibility of the vehicle pedal system.

[0054] Optionally, in an embodiment of the present application, the driving assembly includes a first limit member 13, and the elastic assembly includes a second limit member 31 and an elastic member 32; the elastic member 32 includes a first end and a second end that are set apart from each other, the second limit member 31 is connected to the first end, and the second limit member 31 is engaged with the pedal assembly, and the first limit member 13 is connected to the second end; the pedal assembly drives the second limit member 31 to move, the second limit member 31 drives the first end of the elastic member 32 to extend and retract, and the first limit member 13 drives the second end of the elastic member 32 to move, so that the elastic member 32 is deformed to adjust the feedback force transmitted to the pedal assembly by the elastic member 32 when the pedal assembly drives the first end of the elastic member 32 to extend and retract through the second limit member 31. In this way, the pedal assembly drives the elastic assembly through the second stopper 31, so that when the pedal assembly is stepped on, the first end of the elastic member 32 is driven to expand and contract through the second stopper 31 to generate deformation, and then the second end of the elastic member 32 is driven to expand and contract through the first stopper 13 to adjust the deformation of the elastic member 32, thereby adjusting the pedal feel fed back to the pedal assembly by the elastic member 32. For example, the elastic member 32 can be a spring, or a spring, etc., and the specific type of the elastic member 32 is not limited in the embodiment of the present application.

[0055] In the embodiment of the present application, specifically, the pedal assembly is engaged with the second stopper 31, and the pedal assembly is subjected to the downward pedal force movement, which can drive the second stopper 31 to move upward in the vertical direction, and the second stopper 31 is connected to the first end of the elastic member 32, driving the elastic member 32 to move upward to contract and produce deformation. At this time, the first stopper 13 of the drive assembly can move downward, and the first stopper 13 is connected to the second end of the elastic member 32, which can drive the second end of the elastic member 32 to move downward to further increase the contraction amount and deformation amount, thereby increasing the feedback force of the elastic member 32 fed back to the pedal assembly. In addition, the first stopper 13 of the drive assembly can also move upward, driving the second end of the elastic member 32 to move upward to reduce the contraction amount and deformation amount, thereby reducing the feedback force of the elastic member 32 fed back to the pedal assembly, which can be set according to actual needs, and the embodiment of the present application is not limited to this.

[0056] Optionally, in the embodiment of the present application, the driving assembly further includes a driver 10 and a transmission assembly, the driver 10 is connected to the transmission assembly, and the first stopper 13 is connected to the transmission assembly; the driver 10 drives the transmission assembly to move, and the transmission assembly drives the first stopper 13 to move, so as to drive the second end of the elastic assembly to move. In this way, the driver 10 provides a relatively stable and reliable driving force, and the driving force of the driver 10 is transmitted to the elastic assembly through the transmission assembly, so as to achieve the first stopper 13 to adjust the expansion and contraction amount of the elastic member 32.

[0057] In some optional embodiments of the present application, the transmission assembly includes a rotating shaft 11 and a first gear 12; the rotating shaft 11 is passed through the driver 10 and connected to the output end of the driver 10, the first gear 12 is sleeved on the rotating shaft 11, one end of the first stopper 13 is meshed with the first gear 12, and the other end of the first stopper 13 is connected to the second end of the elastic assembly; the driver 10 drives the first gear 12 to rotate, and the first gear 12 drives the first stopper 13 to move. In this way, a relatively stable and reliable transmission of power is achieved through the first gear 12 and the first stopper 13, so that the driving force of the driver 10 is stably transmitted to the elastic assembly, the first gear 12 rotates to drive the first stopper 13 to move, and the first stopper 13 is used to adjust the expansion and contraction amount of the elastic member 32.

[0058] Specifically, in the embodiment of the present application, the first stopper 13 is engaged with the first gear 12, and the first stopper 13 can extend in the vertical direction. The rotation of the first gear 12 drives the first stopper 13 to move, and the rotational motion of the first gear 12 can be converted into a linear motion in the vertical direction. For example, the driver 10 can be a motor, and the motor is powered on to rotate to provide a driving force, driving the first gear 12 to rotate. In addition, the driver 10 can also be a cylinder, etc., and the embodiment of the present application does not limit the specific type of the driver 10.

[0059] Optionally, in the embodiment of the present application, the first limit member 13 is a limit rod, one end of the limit rod is provided with a first rack, the first rack is meshed with the first gear 12, and the other end of the limit rod is connected to the second end of the elastic component. In this way, the meshing action between the limit rod and the first gear 12 is achieved through the first rack, the structure is relatively compact, and the first limit member 13 and the first gear 12 have a higher force transmission efficiency, and the transmission is relatively stable.

[0060] In an embodiment of the present application, optionally, the pedal assembly includes a pedal 21, a rotating shaft 22 and a second gear 24; the pedal 21 is connected to the rotating shaft 22, the second gear 24 is sleeved on the rotating shaft 22, and the second gear 24 is connected to the second limiting member 31; the pedal 21 drives the rotating shaft 22 to rotate, the rotating shaft 22 drives the second gear 24 to rotate, and the second gear 24 drives the second limiting member 31 to move, so that the second limiting member 31 drives the second end of the elastic member 32 to extend and retract. In this way, when the pedal 21 is stepped on by the driver, the pedal 21 drives the rotating shaft 22 to rotate around the axis of the rotating shaft 22, and the second gear 24 is sleeved on the rotating shaft 22, that is, the second gear 24 rotates coaxially with the rotating shaft 22, and the second limit member 31 is connected to the second gear 24, so that the second gear 24 drives the second limit member 31 to move in the vertical direction, so that the second limit member 31 drives the elastic member 32 to perform telescopic movement, and the elastic member 32 generates feedback force, and transmits the feedback force to the pedal 21 through the second gear 24 and the rotating shaft 22, so that the driver gets a pedal feel.

[0061] Specifically, in the embodiment of the present application, the second limit member 31 is engaged with the second gear 24, and the second limit member 31 can extend in the vertical direction. The rotation of the second gear 24 drives the second limit member 31 to move, and the rotational motion of the second gear 24 can be converted into linear motion in the vertical direction.

[0062] Optionally, in the embodiment of the present application, the vehicle pedal system further includes a fixing frame 23, which is connected to the pedal assembly to fix the pedal assembly. In this way, the pedal assembly has good stability, and the pedal 21 is prevented from shaking easily when being stepped on, resulting in poor structural stability. Specifically, the rotating shaft 22 of the pedal assembly can be connected to the fixing frame 23, and then the pedal 21 is connected to the rotating shaft 22, which has good stability and facilitates the reasonable layout of various components.

[0063] For example, in the embodiment of the present application, the rotating shaft 22 may include a sleeve and a fixed shaft, the sleeve is provided with a hollow cavity, the fixed shaft is passed through the hollow cavity and is rotatably connected to the sleeve. Bearings may be provided at both ends of the sleeve, the fixed shaft is passed through the bearings and is press-fitted with the bearings, and both ends of the fixed shaft are fixedly connected to the fixed frame 23. The pedal 21 is connected to the sleeve, and the sleeve is driven to rotate relative to the fixed shaft when the pedal 21 is stepped on.

[0064] Elastic member 32 Elastic member 32 Specifically, in the embodiment of the present application, the second limiting member 31 is a limiting column, and a second rack is provided on the outer side of the limiting column, and the second rack is meshed with the second gear 24. In this way, the meshing of the limiting column and the second gear 24 is achieved through the second rack, the structure is relatively compact, and the limiting column and the second gear 24 have a higher force transmission efficiency, and the transmission is relatively stable.

[0065] Optionally, in the embodiment of the present application, the vehicle pedal system further includes a controller, the driver 10 is electrically connected to the controller, and the controller controls the driver 10 to drive the first gear 12 to rotate. In this way, the driver 10 can be controlled by the controller to improve the control accuracy, so that the driver 10 drives the first gear 12 to rotate to a desired position. For example, in the embodiment of the present application, the controller can be an on-board computer (Electronic Control Unit, ECU), or a microprocessor (Micro Control Unit, MCU), etc. The embodiment of the present application does not limit the specific type of the controller.

[0066] In the embodiment of the present application, the vehicle pedal system may further include a first induction member 25 and a displacement sensor 26, wherein the first induction member 25 is connected to the elastic component, the displacement sensor 26 is connected to the fixing frame 23, and the displacement sensor 26 is arranged opposite to the first induction member 25; when the driver 10 drives the elastic component to extend and retract, the first induction member 25 moves along the extension and retraction direction of the elastic component, and the displacement sensor 26 is used to detect the displacement generated by the first induction member 25; the controller is electrically connected to the displacement sensor 26, and the controller is used to issue a braking instruction and control the driver 10 to drive the first gear 12 to rotate based on the displacement detected by the displacement sensor 26. In this way, the elastic component performs an extension and retraction movement, driving the first induction member 25 to move, and the displacement generated by the first induction member 25 is detected by the displacement sensor 26 to obtain the compression or elongation generated by the extension and retraction of the spring component, and the feedback force generated by the spring component is obtained based on the compression or elongation. Furthermore, the controller issues a braking command through the displacement detected by the displacement sensor 26 to achieve vehicle hydraulic braking, and the controller can control the driver 10 to drive the first gear 12 to rotate to the required position according to the different requirements of different vehicle models through the displacement detected by the displacement sensor 26, so as to adjust the elastic component to generate the required feedback force through the first limit member 13.

[0067] In the embodiment of the present application, since the first sensing member 25 moves along the expansion and contraction direction of the elastic component, the expansion and contraction change of the elastic component is a linear change, so the displacement change of the first sensing member 25 detected by the displacement sensor 26 is also a linear displacement change, and then the controller can issue a linear braking command based on the linear displacement change. Therefore, the controller can implement the braking command through the same control logic curve, such as the same quadratic equation, which greatly reduces the logical operation amount of the vehicle pedal system, reduces the data storage and operation pressure of the vehicle pedal system, and improves the working efficiency of the vehicle pedal system.

[0068] Compared with the existing related art, the detector detects changes according to the rotation angle of the pedal 21, which are usually nonlinear changes, that is, the detector is triggered to send a braking command to the controller only when the pedal 21 is rotated to a certain angle. For example, when the pedal 21 is rotated to 30°, 45° or 60°, the detector is triggered to send a braking command to the controller. Correspondingly, the controller needs to set corresponding control logic when the pedal 21 is rotated to 30°, 45° or 60°, for example, it needs to be set as a cubic equation, or three equations are set to implement different braking commands respectively, so that the vehicle pedal system has a large amount of logical operations, which makes the data storage and operation pressure of the vehicle pedal system large, and the working efficiency is low.

[0069] For example, in the embodiment of the present application, the first sensing member 25 may be a ferromagnetic member or an electromagnetic member, and the displacement sensor 26 may detect the displacement of the ferromagnetic member or the electromagnetic member through the change of the magnetic field generated by the movement of the ferromagnetic member or the electromagnetic member. The shape of the first sensing member 25 may be rectangular, square, or circular, etc., and the embodiment of the present application may not limit the specific type and shape of the first sensing member 25.

[0070] In the embodiment of the present application, for example, the displacement sensor 26 may be provided with a Hall sensing element and a conditioning chip that are electrically connected to each other. The Hall sensing element can convert the magnetic field change generated by the first sensing member 25 moving with the second limiting member 31 into an electrical signal. The conditioning chip can convert the above electrical signal into an analog signal or a digital signal, and then send the analog signal or digital signal to the controller.

[0071] Optionally, in the embodiment of the present application, the vehicle pedal system further includes an angle sensor 14 and a second sensor 15, wherein the angle sensor 14 is electrically connected to the controller; the second sensor 15 is connected to the rotating shaft 11, the angle sensor 14 is connected to the fixing frame 23, and the angle sensor 14 is arranged corresponding to the second sensor 15, and the angle sensor 14 is used to detect the rotation angle of the second sensor 15 and feed back the rotation angle to the controller. In this way, the driver 10 generates a driving force to drive the rotating shaft 11 to rotate, and the rotating shaft 11 drives the second sensor 15 to rotate. Since the first gear 12 is also connected to the rotating shaft 11, the second sensor 15 rotates coaxially with the first gear 12, and the angle sensor 14 obtains the rotation angle of the first gear 12 by detecting the rotation angle of the second sensor 15. Therefore, the angle sensor 14 sends the rotation angle to the controller, and the controller can confirm the actual rotation angle of the first gear 12 driven by the driver 10 according to the rotation angle fed back by the angle sensor 14, and facilitate timely adjustment.

[0072] For example, in an embodiment of the present application, the second sensing element 15 can be connected to an end of the rotating shaft 11 away from the first gear 12 to avoid mutual interference between the second sensing element 15 and the first gear 12. The angle sensor 14 can be arranged at the tail end of the driver 10, so that the second sensing element 15 and the angle sensor 14 have a better alignment effect, thereby improving the detection accuracy of the angle sensor 14 on the second sensing element 15.

[0073] In the embodiment of the present application, for example, the second sensing member 15 can be a ferromagnetic member or an electromagnetic member, and the angle sensor 14 can detect the rotation angle of the ferromagnetic member or the electromagnetic member through the change of the magnetic field generated by the movement of the ferromagnetic member or the electromagnetic member. The shape of the second sensing member 15 can be circular, elliptical or rectangular, etc., and the embodiment of the present application may not limit the specific type and shape of the second sensing member 15.

[0074] Optionally, in the embodiment of the present application, the vehicle pedal system further includes a brake light, which is electrically connected to the controller; the displacement of the second stopper 31 is provided with a preset threshold value, and when the displacement sensor 26 detects that the displacement of the second stopper 31 is within the preset threshold value, the controller controls the brake light to light up. In this way, the trampling depth of the pedal 21 can be obtained through the displacement of the second stopper 31. When the trampling depth of the pedal 21 reaches a certain threshold value, that is, when the displacement of the second stopper 31 is within the preset threshold value, the displacement sensor 26 can send an instruction to the controller to light up the brake light, so that the controller controls the brake light to light up, and the brake alarm is issued to indicate the current running state of the vehicle. Compared with the existing related art, a brake switch is usually provided on the pedal 21, and the brake switch is electrically connected to the controller. In the embodiment of the present application, the function of lighting up the brake light can be realized without providing a separate brake light. And the displacement change detection of the second stopper 31 by the displacement sensor 26 has good accuracy.

[0075] For example, in the embodiment of the present application, the preset threshold value of the displacement of the second limiting member 31 may be 5-30 mm or 10-50 mm, etc., and may be set according to actual needs, and the embodiment of the present application may not limit this.

[0076] In the embodiment of the present application, the vehicle pedal system may further include a pressure sensor 27, which is connected to the pedal 21 and is electrically connected to the controller; when the pressure sensor 27 detects that the pressure on the pedal 21 is greater than a preset pressure, the controller issues a braking command. In this way, when the pedal 21 is stuck due to foreign matter or other reasons, and it cannot drive the shaft 22 to rotate, the pressure sensor 27 detects that the pressure on the pedal 21 is greater than a preset pressure, and it can be determined that the user has issued a braking demand, and the controller can still issue a braking command to control the vehicle to brake, further improving driving safety.

[0077] For example, in the embodiment of the present application, the preset pressure of the pressure on the pedal 21 detected by the pressure sensor 27 can be 10N, 20N, 30N or 50N, etc., which can be set according to actual needs, and the embodiment of the present application is not limited to this.

[0078] In some optional embodiments of the present application, the pedal 21 includes a pedal arm, a support seat 212 and a pedal body 213; the pedal arm is connected to the rotating shaft 22, the support seat 212 is connected to one end of the pedal arm away from the rotating shaft 22, the pedal body 213 is connected to the support seat 212, and the pressure sensor 27 is connected between the support seat 212 and the pedal body 213. In this way, the pedal 21 is connected to the rotating shaft 22 through the pedal arm, the pedal body 213 is provided with a relatively stable support through the support seat 212, and the pedal body 213 receives the driver's stepping action. For example, the pedal body 213 can produce a small movement toward the support seat 212, so that the pressure sensor 27 has a relatively good pressure detection effect. The pressure sensor 27 is connected between the support seat 212 and the pedal body 213 to avoid the pressure sensor 27 being externalized, so that the pressure sensor 27 is not easily damaged by friction, etc., and the service life of the pressure sensor 27 is extended.

[0079] Specifically, in the embodiment of the present application, the pressure sensor 27 is provided with a sensing diaphragm assembly and a conditioning chip which are electrically connected to each other. The sensing diaphragm assembly can convert the received force signal into an electrical signal, and the conditioning chip can convert the electrical signal into a linear digital signal and send the numerical signal to the controller.

[0080] Optionally, in the embodiment of the present application, the vehicle pedal system further includes a limit frame 33, which is connected to the fixed frame 23; the inner wall of the limit frame 33 is provided with a slide rail, and the second limit member 31 is slidably connected to the slide rail in the vertical direction. In this way, the sliding direction of the second limit member 31 is limited by the limit frame 33, and the second limit member 31 is also protected to a certain extent. For example, the slide rail can be extended in the vertical direction, and the second limit member 31 can slide in the vertical direction along the slide rail, driving the elastic member 32 to perform telescopic movement in the vertical direction to generate feedback force.

[0081] In the embodiment of the present application, optionally, the second stopper 31 is provided with a hollow cavity, the first stopper 13 is passed through the hollow cavity, and the first stopper 13 can slide relative to the second stopper 31. In this way, the second stopper 31 can be integrated with the first stopper 13, and there is no need to provide space for the second stopper 31 and the first stopper 13 respectively, which saves the space occupied by the first stopper 13 and improves the space utilization rate.

[0082] For example, in the embodiment of the present application, a support plate may be provided at one end of the first limit member 13, and the support plate is connected to the other end of the elastic member 32, so that the first limit member 13 can better drive the elastic member 32 to perform telescopic movement through the support plate.

[0083] In summary, the vehicle pedal system described in the embodiment of the present application can at least include the following advantages:

[0084] In an embodiment of the present application, the vehicle pedal system includes: a pedal assembly, an elastic assembly and a drive assembly; the pedal assembly and the drive assembly are respectively connected to the elastic assembly; the drive assembly controls the elastic assembly to produce deformation, so as to adjust the feedback force transmitted to the pedal assembly by the elastic assembly when the pedal assembly drives the elastic assembly to extend and retract. In this way, when the pedal assembly is stepped on, the pedal assembly drives the elastic assembly to move, and the elastic assembly is deformed. At this time, the elastic assembly is adjusted to extend and retract by the drive assembly, so that the elastic assembly can generate the required degree of feedback force, so that the drive assembly can be set to drive the elastic assembly to produce different moving distances for different vehicle models, so as to produce different extension amounts, thereby generating different feedback forces transmitted to the pedal assembly. As a result, it can be applied to different vehicle models to give users different degrees of pedal feel, so that the elastic assembly can be universal for different vehicle models, thereby improving the compatibility of the vehicle pedal system.

[0085] An embodiment of the present application also provides a vehicle, which includes the vehicle pedal system.

[0086] For example, in the embodiments of the present application, the vehicles may include compact cars, medium-sized cars, three-box cars, trucks, trailers, CDVs (Car Derived Vans), MPVs (multi-Purpose Vehicles), SUVs (Sport Utility Vehicles), etc. The embodiments of the present application may not limit the specific types of the vehicles.
