[0035] Combine the following Figure 1-Figure 4 The drive-by-wire pedal 10 , the automatic driving system and the vehicle according to the embodiment of the present invention are described in detail.

[0036] Reference Figure 1-Figure 4As shown, according to an embodiment of the present invention, the wire-controlled pedal 10 includes: a pedal 1, a connecting member 2, an angle adjustment mechanism 3, a position adjustment mechanism 4, a height adjustment mechanism 5 and a detection device 6. The pedal 1 has a tread surface 11, the connecting member 2 has a first connection end 21 and a second connection end 22, the first connection end 21 is rotatably connected to the pedal 1 around a first axis L1, the angle adjustment mechanism 3 is connected between the connecting member 2 and the pedal 1, the angle adjustment mechanism 3 is used to drive the pedal 1 to rotate around the first axis L1 relative to the connecting member 2, the position adjustment mechanism 4 is suitable for being installed on the floor of the vehicle, the second connection end 22 is rotatably connected to the position adjustment mechanism 4 around the second axis L2, the position adjustment mechanism 4 is used to drive the connecting member 2 to move along the first direction, the height adjustment mechanism 5 is connected between the connecting member 2 and the position adjustment mechanism 4, the height adjustment mechanism 5 is used to drive the connecting member 2 to rotate around the second axis L2 relative to the position adjustment mechanism 4, the detection device 6 is used to detect the pressure value applied to the tread surface 11, and send the pressure value information to the ECU of the vehicle, wherein the first axis L1 is parallel to the second axis L2, and the first direction is perpendicular to the first axis L1.

[0037] It should be noted that the wire-controlled pedal 10 can be applied to vehicles. The wire-controlled pedal 10 can be a vehicle brake pedal. The tread surface 11 of the pedal 1 can be stepped on by the driver. When the driver steps on the tread surface 11, the detection device 6 can detect the pressure value of the tread surface 11 and send the pressure value information to the vehicle's ECU. The ECU can control the vehicle to generate corresponding braking force according to the pressure value, thereby realizing the vehicle's wire-controlled braking. For example, the greater the pedaling force, the greater the pressure on the tread surface 11, and the greater the braking force generated by the ECU controlling the vehicle.

[0038] It can be understood that the angle adjustment mechanism 3 can adjust the angle of the tread surface 11, the position adjustment mechanism 4 can adjust the position of the tread surface 11 in the front and rear direction of the vehicle, and the height adjustment mechanism 5 can adjust the height of the tread surface 11. The driver can adjust the angle, front and rear position and height of the tread surface 11 according to his or her own needs, and the wire-controlled pedal 10 can realize the folding and storage function, which can optimize the foot space and help improve the driver's driving experience.

[0039] Specifically, the first axis L1 and the second axis L2 are both parallel to the tread surface 11, both extend in the left-right direction of the vehicle, and are parallel to the floor of the vehicle. When the angle adjustment mechanism 3 drives the pedal 1 to rotate around the first axis L1 relative to the connecting member 2, the angle between the tread surface 11 and the floor of the vehicle will change, thereby adjusting the angle of the tread surface 11.

[0040] The first direction can be the front-to-back direction of the vehicle. When the position adjustment mechanism 4 drives the connecting member 2 to move along the first direction, the connecting member 2 can drive the angle adjustment mechanism 3 to move along the first direction, and the angle adjustment mechanism 3 can drive the pedal 1 to move along the first direction, thereby adjusting the position of the tread surface 11 in the front-to-back direction of the vehicle.

[0041] When the height adjustment mechanism 5 drives the connecting member 2 to rotate around the second axis L2 relative to the position adjustment mechanism 4, the second connecting end 22 of the connecting member 2 rotates around the second axis L2 and the first connecting end 21 revolves around the second axis L2 to adjust the height of the first connecting end 21. The first connecting end 21 can drive the angle adjustment mechanism 3 and the pedal 1 as a whole to rise and fall in the up and down directions, thereby adjusting the height of the tread surface 11.

[0042] Reference Figure 3 As shown, when the angle adjustment mechanism 3 drives the pedal 1 to rotate counterclockwise ( Figure 3 The height adjustment mechanism 5 drives the connecting member 2 to rotate clockwise (in the direction of a) around the second axis L2. Figure 3 When the control-by-wire pedal 10 is rotated in the middle and b directions, the angles α and β can be reduced respectively, so that the folding and storage function of the control-by-wire pedal 10 can be realized, the height of the control-by-wire pedal 10 can be lowered, and the space occupied by the control-by-wire pedal 10 in the up and down directions can be reduced, thereby optimizing the foot space and improving the driver's driving experience.

[0043] In this embodiment, the mechanical mechanism of the wire-controlled pedal 10 does not need to be directly connected to the vehicle's brake system, and can achieve decoupling braking, so as to realize the folding and storage function, facilitate operation, and reduce the noise caused by friction and vibration of the mechanical mechanism. In addition, when the vehicle is in the automatic driving mode, the wire-controlled pedal 10 can be folded and stored to optimize the foot space, which is conducive to improving the driver's driving experience.

[0044] The wire-controlled pedal 10 according to the embodiment of the present invention can realize wire-controlled braking. Its angle adjustment mechanism 3 can adjust the angle of the tread surface 11, the position adjustment mechanism 4 can adjust the position of the tread surface 11 in the front and rear directions of the vehicle, and the height adjustment mechanism 5 can adjust the height of the tread surface 11. The driver can adjust the angle, front and rear position and height of the tread surface 11 according to his or her own needs. The wire-controlled pedal 10 can realize the folding and storage function, which can optimize the foot space and help improve the driver's driving experience.

[0045] In some embodiments of the present invention, reference Figure 4As shown, the angle adjustment mechanism 3 includes: a first rotating component 31 and a first driving component 32. The first rotating component 31 is rotatably connected to the first connecting end 21 around the first axis L1. The first rotating component 31 is also fixedly connected to the pedal 1. The first driving component 32 is fixedly connected to the connecting member 2. The first driving component 32 is used to drive the first rotating component 31 to rotate around the first axis L1.

[0046] It is understandable that when the first driving assembly 32 drives the first rotating assembly 31 to rotate around the first axis L1, since the first rotating assembly 31 is fixedly connected to the pedal 1, the first rotating assembly 31 can drive the pedal 1 to rotate synchronously around the first axis L1, thereby adjusting the angle of the tread surface 11.

[0047] In other embodiments of the present invention not shown in the figures, the angle adjustment mechanism 3 can be an electric telescopic rod, one end of the electric telescopic rod is fixedly connected to the connecting member 2, and the other end of the electric telescopic rod is rotatably connected to the pedal 1. The extension or shortening of the electric telescopic rod can drive the pedal 1 to rotate around the first axis L1 relative to the connecting member 2, thereby adjusting the angle of the pedal 1.

[0048] In some embodiments of the present invention, reference Figure 1 , Figure 2 and Figure 4 As shown, the first rotating component 31 includes: a first shaft tube 311 and a first tooth plate 312, the first shaft tube 311 is rotatably connected to the first connecting end 21 around the first axis L1, both axial ends of the first shaft tube 311 are fixedly connected to the pedal 1, the first tooth plate 312 is fixedly connected to the first shaft tube 311, and the first driving component 32 includes: a first motor 321 and a first gear 322, the first motor 321 is fixedly connected to the connecting member 2, the first motor 321 has a first output shaft, the first gear 322 is fixedly arranged on the first output shaft, and the first gear 322 is meshed with the first tooth plate 312.

[0049] Among them, the first connecting end 21 can be provided with a bearing, and the first shaft tube 311 is inserted into the bearing to achieve a rotatable connection with the first connecting end 21 around the first axis L1. Both ends of the axis of the first shaft tube 311 can be fixedly connected to the pedal 1 by pins, the first tooth plate 312 and the first shaft tube 311 can be fixedly connected by pins, the first motor 321 can be fixedly connected to the connecting member 2 by screws, and the first gear 322 can be fixedly connected to the first output shaft of the first motor 321 by a fixing key.

[0050] It can be understood that when the first output shaft of the first motor 321 rotates, the first output shaft can drive the first gear 322 to rotate, and the first gear 322 can drive the first tooth plate 312 to rotate around the first axis L1. Since the first tooth plate 312 is fixedly connected to the first shaft tube 311, and the first shaft tube 311 is fixedly connected to the pedal 1, the first tooth plate 312 can drive the first shaft tube 311 to rotate around the first axis L1, and the first shaft tube 311 can drive the pedal 1 to rotate around the first axis L1, thereby adjusting the angle of the tread surface 11. The angle adjustment mechanism 3 has a compact structure and can save space. Through the meshing transmission of the first gear 322 and the first tooth plate 312, it is easy to realize the folding and storage of the wire-controlled pedal 10, and a larger folding angle can be achieved. After the wire-controlled pedal 10 is folded, a large space can be saved.

[0051] In the embodiments shown in other figures of the present invention, the first rotating component 31 includes: a rotating shaft and a first adjusting gear, the first adjusting gear is sleeved on the rotating shaft and fixedly connected to the rotating shaft, the rotating shaft is fixedly connected to the pedal 1, and the first driving member 32 includes: a first driving motor and a first driving gear, the output shaft of the first driving motor is fixedly connected to the first driving gear, the first driving motor is fixedly connected to the connecting member 2, the first driving gear is meshed with the first adjusting gear, when the output shaft of the first driving motor rotates, the output shaft can drive the first driving gear to rotate, the first driving gear can drive the first adjusting gear to rotate, and the first adjusting gear can drive the rotating shaft and the pedal 1 to rotate as a whole, so as to adjust the angle of the tread surface 11.

[0052] In some embodiments of the present invention, reference Figure 1 , Figure 2 and Figure 4 As shown, the height adjustment mechanism 5 includes: a second rotating component 51 and a second driving component 52. The second rotating component 51 is fixedly connected to the position adjustment mechanism 4. The second rotating component 51 is also rotatably connected to the second connecting end 22 around the second axis L2. The second driving component 52 is fixedly connected to the connecting member 2. The second driving component 52 is used to drive the connecting member 2 to rotate around the second axis L2 relative to the second rotating component 51.

[0053] It can be understood that when the second driving component 52 drives the connecting member 2 to rotate around the second axis L2 relative to the second rotating component 51, the second connecting end 22 rotates around the second axis L2 and the first connecting end 21 revolves around the second axis L2 to adjust the height of the first connecting end 21, so that the first connecting end 21 can drive the angle adjustment mechanism 3 and the pedal 1 as a whole to rise and fall in the up and down directions, thereby adjusting the height of the tread surface 11.

[0054] In other embodiments of the present invention not shown in the figures, the height adjustment mechanism 5 can be an electric telescopic rod, one end of which is fixedly connected to the position adjustment mechanism 4, and the other end of the electric telescopic rod is rotatably connected to the connecting member 2. The extension or shortening of the electric telescopic rod can drive the connecting member 2 to rotate around the second axis L2 relative to the position adjustment mechanism 4 to adjust the height of the first connecting end 21. The first connecting end 21 can drive the angle adjustment mechanism 3 and the pedal 1 as a whole to rise and fall in the up and down directions, thereby adjusting the height of the tread surface 11.

[0055] In some embodiments of the present invention, reference Figure 1 , Figure 2 and Figure 4 As shown, the second rotating component 51 includes: a second shaft tube 511 and a second gear plate 512, the second shaft tube 511 is fixedly connected to the position adjustment mechanism 4, the second shaft tube 511 is also rotatably connected to the second connecting end 22 around the second axis L2, the second gear plate 512 is fixedly connected to the second shaft tube 511, and the second driving component 52 includes: a second motor 521 and a second gear 522, the second motor 521 is fixedly connected to the connecting member 2, the second motor 521 has a second output shaft, the second gear 522 is fixedly arranged on the second output shaft, and the second gear 522 is meshed with the second gear plate 512.

[0056] Among them, the second shaft tube 511 can be fixedly connected to the position adjustment mechanism 4 by a pin, the second connecting end 22 can be provided with a bearing, the second shaft tube 511 is passed through the bearing to achieve a rotatable connection with the second connecting end 22 around the second axis L2, the second gear plate 512 can be fixedly connected to the second shaft tube 511 by a pin, the second motor 521 can be fixedly connected to the connecting member 2 by a screw, and the second gear 522 can be fixedly connected to the second output shaft of the second motor 521 by a fixing key.

[0057] It can be understood that when the second output shaft of the second motor 521 rotates, the second output shaft can drive the second gear 522 to rotate synchronously. Since the second gear 522 is meshed with the second tooth plate 512, the second gear 522 rotates relative to the second tooth plate 512 around the second axis L2. The second gear 522 can drive the second motor 521 and the connecting member 2 to rotate synchronously around the second axis L2 as a whole, so that the first connecting end 21 of the connecting member 2 revolves around the second axis L2, and the height of the first connecting end 21 is adjusted. The first connecting end 21 can drive the angle adjustment mechanism 3 and the pedal 1 as a whole to move up and down in the vertical direction, thereby adjusting the height of the tread surface 11. The height adjustment mechanism 5 has a compact structure and can save space. Through the meshing transmission of the second gear 522 and the second tooth plate 512, it is easy to realize the folding and storage of the wire-controlled pedal 10, and a larger folding angle can be achieved. After the wire-controlled pedal 10 is folded, a large space can be saved.

[0058] In other embodiments of the present invention not shown in the figures, the second rotating component 51 includes: a fixed shaft and a second adjusting gear, the second adjusting gear is sleeved on the fixed shaft and fixedly connected to the fixed shaft, the fixed shaft is fixedly connected to the position adjustment mechanism 4, the second driving component 52 includes: a second driving motor and a second driving gear, the output shaft of the second driving motor is fixedly connected to the second driving gear, the second driving motor is fixedly connected to the connecting member 2, the second driving gear is meshed with the second adjusting gear, when the output shaft of the second driving motor rotates, the output shaft can drive the second driving gear to rotate, the second driving gear can rotate around the second axis L2 relative to the second adjusting gear, the second adjusting gear can drive the second driving motor to rotate, so that the second driving motor can drive the connecting member 2 to rotate, and the second connecting end 22 of the connecting member 2 can drive the angle adjustment mechanism 3 and the pedal 1 to rise and fall as a whole, so as to adjust the height of the treading surface 11.

[0059] In some embodiments of the present invention, reference Figure 1 , Figure 2 and Figure 4 As shown, the position adjustment mechanism 4 includes: a guide rail 41, a nut seat 42, a screw rod 43, a third gear 44, a slider 45 and a third motor 46. The guide rail 41 is suitable for being fixedly connected to the floor, and the guide rail 41 extends along a first direction. The nut seat 42 is fixedly connected to the guide rail 41, the screw rod 43 is threadedly matched with the nut seat 42, and the axial direction of the screw rod 43 is parallel to the first direction. The third gear 44 is fixed to the screw rod 43, and the slider 45 is connected to the second shaft tube 511. In the first direction, the slider 45 is slidably matched with the guide rail 41, and the slider 45 is limitedly matched with the third gear 44. The third motor 46 is fixed to the slider 45, and the third motor 46 is transmission connected to the third gear 44.

[0060] It can be understood that the third motor 46 can drive the third gear 44 to rotate. When the third gear 44 rotates, the third gear 44 can drive the screw rod 43 to rotate synchronously. Since the screw rod 43 is threadedly matched with the nut seat 42, the screw rod 43 can move in the first direction relative to the nut seat 42 when it rotates. The screw rod 43 can drive the third gear 44 fixed on the screw rod 43 to move synchronously in the first direction. Since the slider 45 is limitedly matched with the third gear 44 and the slider 45 is connected to the second shaft tube 511, the third gear 44 can drive the slider 45 to move in the first direction, the slider 45 can drive the second shaft tube 511 to move in the first direction, the second shaft tube 511 can drive the connecting member 2 to move in the first direction, and the connecting member 2 can drive the angle adjustment mechanism 3 and the pedal 1 as a whole to move in the first direction, thereby adjusting the position of the tread surface 11 in the front and rear direction of the vehicle.

[0061] Specifically, since the third motor 46 is fixed to the slider 45, the overall structure of the wire-controlled pedal 10 is compact, which is conducive to saving space. When the slider 45 moves along the first direction, the slider 45 can drive the third motor 46 to move synchronously, and the transmission connection between the third motor 46 and the third gear 44 can be maintained, which is conducive to stably adjusting the front and rear position of the pedal surface 11.

[0062] In other embodiments of the present invention, the position adjustment mechanism 4 can be a cylinder, which includes a cylinder body and a piston rod. The piston rod extends along a first direction, the cylinder body can be fixedly connected to the floor of the vehicle, and the piston rod can be fixedly connected to the second shaft tube 511. The movement of the piston rod relative to the cylinder body along the first direction can drive the second shaft tube 511 to move along the first direction, so that the second shaft tube 511 can drive the connecting member 2 to move along the first direction, and the connecting member 2 can drive the angle adjustment mechanism 3 and the pedal 1 as a whole to move along the first direction, thereby adjusting the position of the tread surface 11 in the front and rear direction of the vehicle.

[0063] In some embodiments of the present invention, reference Figure 1 , Figure 2 and Figure 4 As shown, the position adjustment mechanism 4 also includes: a first support rod 47, one end of the first support rod 47 is rotatably connected to the slider 45 around the third axis L3, and the other end of the first support rod 47 is fixedly connected to the second shaft tube 511, and the wire-controlled pedal 10 also includes: a second support rod 7, one end of the second support rod 7 is rotatably connected to the slider 45 around the fourth axis L4, and the other end of the second support rod 7 is rotatably connected to the connecting member 2 around the fifth axis L5, wherein the second axis L2, the third axis L3, the fourth axis L4 and the fifth axis L5 are parallel, and in the first direction, the first support rod 47 and the second support rod 7 are spaced apart.

[0064] It can be understood that the first support rod 47 and the second support rod 7 can support the overall structure composed of the connecting member 2, the angle adjustment mechanism 3 and the pedal 1 at different positions respectively, so as to provide reliable support for the pedal 1 when the driver steps on the treading surface 11 of the pedal 1, avoid the pedal 1 from shaking, ensure the stability of the pedal 1, and facilitate the detection device 6 to accurately detect the pressure value of the treading surface 11, and the first support rod 47, the slider 45, the second support rod 7 and the connecting member 2 can form a four-bar linkage mechanism, which is convenient for the wire-controlled pedal 10 to be folded.

[0065] In some embodiments of the present invention, the detection device 6 includes: a pressure sensor and a calibration sensor. The pressure sensor is arranged on the tread surface 11. The pressure sensor is used to detect the pressure value of the tread surface 11 and send the pressure value information to the ECU. The calibration sensor is used to indirectly detect the pressure value of the tread surface 11 to obtain calibration information and send the calibration information to the ECU. The ECU can verify whether the pressure value detected by the pressure sensor is accurate according to the calibration information sent by the calibration sensor.

[0066] It can be understood that when the pressure value detected by the calibration sensor is consistent with the pressure value detected by the pressure sensor, it indicates that the pressure value detected by the pressure sensor is accurate. The ECU can accurately control the braking force of the vehicle according to the pressure value detected by the pressure sensor, that is, control the vehicle to produce the corresponding deceleration.

[0067] When the pressure value detected by the calibration sensor is inconsistent with the pressure value detected by the pressure sensor, or when one of the signals of the calibration sensor and the pressure sensor is lost, it is impossible to determine whether the pressure value detected by the pressure sensor is accurate. The ECU will report an error after continuous detection for a specified time (3ms~5ms), and the vehicle's instrument can warn the driver to slow down and stop. The driver can slow down and stop by stepping on pedal 1. At this time, since the ECU cannot determine whether the pressure value detected by the pressure sensor is accurate, the ECU can control the vehicle to slow down and stop with a fixed braking force. The driver can also turn on the vehicle's automatic driving mode and control the vehicle to park safely on the roadside through automatic driving.

[0068] Among them, the pressure sensor can be a capacitive sensor, and the verification sensor can be a strain gauge sensor. When the driver steps on the tread surface 11, the pressure sensor can directly detect the pressure value of the tread surface 11 through the change of its own capacitance. The verification sensor can be arranged on the side of the pedal 1 away from the tread surface 11, and the pressure exerted on the tread surface 11 can be transmitted to the side of the pedal 1 away from the tread surface 11. The verification sensor can indirectly detect the pressure value exerted on the tread surface 11 by detecting the deformation amount of the side of the pedal 1 away from the tread surface 11. The verification sensor can also be arranged on the second shaft tube 511. The pressure exerted on the pedal 1 can be transmitted to the second shaft tube 511. The verification sensor can indirectly detect the pressure value exerted on the tread surface 11 by detecting the deformation amount of the second shaft tube 511.

[0069] In some embodiments of the present invention, there are two connecting members 2, and the two connecting members 2 are spaced apart in the left-right direction. The two connecting members 2 can jointly support the angle adjustment mechanism 3 and the pedal 1 as a whole to provide reliable support for the pedal 1, avoid shaking of the pedal 1, ensure the stability of the pedal 1, and facilitate the detection device 6 to accurately detect the pressure value of the tread surface 11.

[0070] In some embodiments of the present invention, reference Figure 1 , Figure 2 and Figure 4 As shown, the slider 45 includes a first sub-slider 451, a second sub-slider 452, a third sub-slider 453 and a fourth sub-slider 454. The second sub-slider 452, the third sub-slider 453 and the fourth sub-slider 454 are all connected to the first sub-slider 451. The first sub-slider 451 can be constructed as a rectangular tube structure. The first sub-slider 451 is arranged in the guide rail 41 and slides with the guide rail 41 along the first direction. The screw rod 43 is penetrated by the first sub-slider 451, and the first sub-slider 451 is limited in the first direction with the third gear 44. When the third gear 44 rotates, the third gear 44 and the screw rod 43 rotate synchronously as a whole, and the screw rod 43 and the third gear 44 move as a whole along the first direction. Since the first sub-slider 451 and the third gear 44 are limited in the first direction, the third gear 44 can drive the first sub-slider 451 to move synchronously along the first direction, so that the first sub-slider 451 can drive the second sub-slider 452, the third sub-slider 453 and the fourth sub-slider 454 to move synchronously along the first direction.

[0071] The third motor 46 is fixed to the second sub-slider 452, and the fourth gear 461 is connected to the output shaft of the third motor 46, and the fourth gear 461 is transmission connected to the third gear 44. In the first direction, the third sub-slider 453 and the fourth sub-slider 454 are spaced apart on both sides of the second sub-slider 452, the first support rod 47 is connected to the third sub-slider 453, and the second support rod 7 is connected to the fourth sub-slider 454. The third sub-slider 453 can be connected to the second shaft tube 511 through the first support rod 47, so as to realize the indirect connection between the second shaft tube 511 and the slider 45, and the third sub-slider 453 and the fourth sub-slider 454 are both constructed as "U"-shaped plates, which is beneficial to improving the structural strength of the third sub-slider 453 and the fourth sub-slider 454.

[0072] The guide rail 41, the nut seat 42, the screw rod 43, the third gear 44, the first sub-slider 451, the third sub-slider 453 and the fourth sub-slider 454 can together form a slide rail and slide block mechanism, referring to Figure 1 and Figure 2 As shown, there are two slide rail slider mechanisms, which are spaced apart in the left-right direction, and the second sub-slider 452 is simultaneously connected to the first sub-slider 451 of the two slide rail slider mechanisms. The two slide rail slider mechanisms can jointly support the height adjustment mechanism 5, the angle adjustment mechanism 3 and the pedal 1 as a whole, so as to provide reliable support for the pedal 1, avoid shaking of the pedal 1, ensure the stability of the pedal 1, and facilitate the detection device 6 to accurately detect the pressure value of the tread surface 11.

[0073] In some embodiments of the present invention, the first motor 321 of the angle adjustment mechanism 3, the third motor 46 of the position adjustment mechanism 4 and the second motor 521 of the height adjustment mechanism 5 are all connected to the vehicle's ECU for communication, and the vehicle's center console has control buttons for respectively adjusting the angle, front and rear position and height of the tread surface 11, and are all connected to the ECU for communication.

[0074] When the driver needs to adjust the angle position of the tread surface 11, he can press the control button for adjusting the angle position of the tread surface 11 when the vehicle is stationary. After the ECU recognizes that the control button has been pressed, the ECU can send a control signal to the first motor 321 to control the operation of the first motor 321 to adjust the angle position of the tread surface 11. The ECU has a memory function and can record the adjusted angle position of the tread surface 11 so that the driver can directly adjust it to that specific position the next time he drives the vehicle.

[0075] When the driver needs to adjust the front and rear position of the tread surface 11, he can press the control button for adjusting the front and rear position of the tread surface 11 when the vehicle is stationary. After the ECU recognizes that the control button has been pressed, the ECU can send a control signal to the third motor 46 to control the operation of the third motor 46 to adjust the front and rear position of the tread surface 11. The ECU has a memory function, which can record the front and rear position of the tread surface 11 after adjustment, so that the driver can directly adjust to this specific position the next time he drives the vehicle.

[0076] When the driver needs to adjust the height of the tread surface 11, he can press the control button for adjusting the height of the tread surface 11 when the vehicle is stationary. After the ECU recognizes that the control button has been pressed, the ECU can send a control signal to the second motor 521 to control the operation of the second motor 521 to adjust the height of the tread surface 11. The ECU has a memory function, which can record the height of the tread surface 11 after adjustment, so that the driver can directly adjust it to that specific position the next time he drives the vehicle.

[0077] Specifically, the vehicle's center console has a reset button, which is communicated with the ECU. The next time the driver drives the vehicle, he can press the reset button. After the ECU recognizes that the control button is pressed, the ECU can simultaneously send a control signal to the first motor 321, the third motor 46 and the second motor 521 to adjust the tread surface 11 to the recorded position. The driver does not need to adjust the angle, front and rear position and height of the tread surface 11 separately again, which is beneficial to improving the driver's driving experience.

[0078] In some embodiments of the present invention, the position adjustment of pedal 1 can be combined with the gear position and driving mode of the vehicle. Specifically, when the vehicle is set to P gear or locked and the driver leaves, pedal 1 can be directly folded and retracted or automatically adjusted to a custom position. When the vehicle is started and awakened, pedal 1 can be automatically unfolded to the recorded usage position. When the vehicle driving mode is set to comfort or sport, different pedal 1 positions and angles can be adjusted to match different mode requirements. When the vehicle is set to automatic driving mode, pedal 1 can be directly folded and retracted to optimize foot space. When the vehicle is set to manual driving mode, pedal 1 can be redeployed to the recorded usage position.

[0079] According to the wire-controlled pedal 10 of the embodiment of the present invention, electrical components (pressure sensor, calibration sensor) and chips (ECU) are used to realize wire-controlled braking of the vehicle, which can reduce mechanical structure connections. The angle, front and rear position and height of the tread surface 11 can be electrically adjusted by using the angle adjustment mechanism 3, the position adjustment mechanism 4 and the height adjustment mechanism 5, respectively. The position can be freely adjusted according to the driver's needs. In this embodiment, the wire-controlled pedal 10 can be arranged on the bottom surface of the cockpit and has a small size. The wire-controlled pedal 10 can increase the space of the cockpit without sacrificing driving comfort, and the driver's riding experience can be improved through customized adjustment.
