[0030] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] The embodiment of the present invention provides an electronic accelerator pedal with a footrest mode, as shown in the attached Figure 1 As shown, the electronic accelerator pedal comprises a pedal surface 1, a pedal base 2, a locking device and a driving device; the pedal surface 1 and the pedal base 2 are hinged;

[0032] The locking device is connected to the pedal base 2, and the locking device can move relative to the pedal base 2 toward or away from the pedal surface 1;

[0033] The locking device is also connected to the driving device, and the driving device is fixed on the pedal base 2;

[0034] The driving device is used to drive the locking device to move to the pedal surface 1 to lock the pedal surface 1 when the vehicle enters the automatic driving mode; when the vehicle exits the automatic driving mode, the driving locking device moves away from the pedal surface 1 to unlock the pedal surface 1.

[0035] In the embodiment of the present invention, one end of the pedal surface 1 is hinged to the pedal base 2 through the pedal shaft; the locking device is located near the other end of the pedal surface. When the pedal surface 1 is not locked by the locking device and is in the unlocked state, the pedal surface 1 can rotate around the pedal shaft by stepping on it, thereby outputting a voltage signal to adjust the vehicle speed; when the pedal surface 1 is in the locked state, the pedal surface 1 will no longer rotate even if a force is applied, that is, the vehicle speed cannot be adjusted. The locking device is arranged near the other end of the pedal surface, which can ensure the locking effect and locking stability of the locking device on the pedal surface.

[0036] In the embodiment of the present invention, the position of the pedal surface when it is not under pressure is set as the initial position of the pedal surface. When the pedal surface is at the initial position, the output voltage of the electronic accelerator pedal is 0, and the vehicle speed is not adjusted.

[0037] In an embodiment of the present invention, a locking device is set between the pedal surface 1 and the pedal base 2, and one end of the locking device is connected to the driving device; when the pedal surface is in the initial position, the other end of the locking device can move to contact the pedal surface 1, so that the pedal surface 1 cannot rotate, thereby locking the pedal surface 1.

[0038] like Figure 2 As shown, in an embodiment of the present invention, a locking device is arranged between the pedal surface 1 and the pedal base 2. When the vehicle is in the automatic driving mode, the locking device is controlled to move to contact the pedal surface 1, so that the pedal surface 1 can be supported and the position of the pedal surface 1 can be locked, thereby realizing the footrest mode of the electronic accelerator pedal.

[0039] In an embodiment of the present invention, one end of the locking device is limited to be connected to the driving device, and the other end of the locking device is set to a ball head; when the locking device locks the position of the pedal surface, the locking device makes spherical contact with the pedal surface through the ball head, thereby improving the stability and reliability of the use of the electronic throttle pedal while ensuring the locking effect of the locking device on the pedal surface.

[0040] In the embodiment of the present invention, the locking device is also connected to the guide structure, and a guide groove is provided on the pedal base 2; the guide structure is connected to the guide groove, and the guide structure can move along the guide groove. By providing the guide structure and the guide groove, the locking device can be guided during the movement of the locking device, and when the locking device locks the pedal surface, the side of the locking device can be supported, thereby improving the stability and reliability of locking the pedal surface.

[0041] As an embodiment, the locking device is an adjusting nut 5; the driving device includes an adjusting bolt 4 and a power device, the power device is connected to the pedal base 2, and the adjusting bolt 4 is connected to the power device; the adjusting nut 5 is threadedly connected to the adjusting bolt 4; the power device can drive the adjusting bolt 4 to rotate, and the adjusting bolt 4 drives the adjusting nut 2 to move towards or away from the pedal surface 1.

[0042] Preferably, the power device selects a drive motor 3, one end of the adjustment bolt 4 is connected to the motor output shaft of the drive motor 3, one end of the adjustment nut 5 is threadedly connected to the adjustment bolt 4, and the other end of the adjustment nut 5 is configured as a ball head for contacting the pedal surface 1.

[0043] When the driving motor 3 rotates clockwise, it can drive the adjusting nut 5 to move along the axial direction of the adjusting nut 5 toward the pedal surface 1; when the driving motor 3 rotates counterclockwise, it can drive the adjusting nut 5 to move along the axial direction of the adjusting nut 5 toward the pedal surface 1. The moving distance of the adjusting nut 5 is controlled by controlling the number of rotations of the driving motor.

[0044] Two guide plates are arranged on the outer wall of the adjusting nut 5, and the two guide plates are arranged symmetrically, and the guide plates are used as guiding structures; two mutually symmetrical guide grooves are arranged on the corresponding pedal base 2, and the two guide plates are placed in the two guide grooves correspondingly to provide guidance for the movement of the adjusting nut 5.

[0045] In order to facilitate accurate control of the moving distance of the locking device, the locking device can accurately move to the pedal surface each time and accurately lock the pedal surface. It is stipulated that each time the pedal surface is unlocked, the driving device drives the locking device back to the initial position, such as Figure 3 As shown, when the locking device is in the initial position, the driver can step on the pedal surface to rotate the pedal surface and output a corresponding voltage value to control the vehicle speed. At this time, the electronic accelerator pedal is in the acceleration pedal mode.

[0046] The embodiment of the present invention connects the driving device to the controller;

[0047] The controller is used to control the driving device to drive the locking device to move to the pedal surface to lock the pedal surface when the vehicle enters the automatic driving mode; when the vehicle exits the automatic driving mode, the controller drives the locking device to move away from the pedal surface to the initial position to unlock the pedal surface.

[0048] Preferably, the controller is used to determine that the vehicle is in automatic driving mode upon receiving a signal to start the automatic driving mode of the vehicle; and is used to determine that the vehicle is exiting the automatic driving mode upon receiving a signal to exit the automatic driving mode of the vehicle.

[0049] The electronic accelerator pedal with a footrest mode disclosed in this embodiment can automatically identify whether the vehicle is in or out of the automatic driving mode. When entering or exiting the automatic driving mode, the driving device is controlled to push the locking device to move in a direction close to or away from the pedal surface, and the pedal surface is locked or unlocked, thereby realizing the switching of the electronic accelerator pedal between the accelerator pedal mode and the footrest mode. When the vehicle is in the automatic driving mode, the electronic accelerator pedal is switched to the footrest mode, allowing the right foot to rest, and the vehicle speed will not be controlled, thereby ensuring the stability of the automatic driving; when the vehicle exits the automatic driving mode, the electronic accelerator pedal is switched to the accelerator pedal mode, and the driver controls the vehicle speed by stepping on the accelerator pedal.

[0050] The embodiment of the present invention further provides a control method of an electronic accelerator pedal with a footrest mode, comprising:

[0051] When the vehicle is in automatic driving mode, the driving device drives the locking device to move to the pedal surface to lock the pedal surface;

[0052] When the vehicle exits the automatic driving mode, the driving device drives the locking device to move away from the pedal surface to unlock the pedal surface.

[0053] Those of ordinary skill in the art will appreciate that the units and algorithm steps of each example described in conjunction with this embodiment can be implemented in electronic hardware or a combination of computer software and electronic hardware. Whether these functions are performed in hardware or software depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of this application.

[0054] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
