Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0037] The vehicle acceleration and braking system provided in the embodiment of the present application is applied to a vehicle. It should be noted here that the vehicle mentioned in the embodiment of the present application may refer to a large car, a small car, a special-purpose vehicle, etc. For example, according to the vehicle model, the vehicle in the embodiment of the present application may refer to a sedan model, an off-road vehicle model, or a multi-purpose vehicle (MPV) or other vehicle models.

[0038] Specifically, the embodiment of the present application provides a vehicle acceleration and braking system, referring to Figure 1 The vehicle acceleration and braking system includes an acceleration component 1, a braking component 2, a displacement component 3 and a pedal feel control component 4, wherein the acceleration component 1 includes an accelerator pedal 11 and an accelerator switch 12; the braking component 2 includes a brake pedal 21 and a brake switch 22; the displacement component 3 is connected to the accelerator pedal 11 and the brake pedal 21, and the displacement component 3 generates an acceleration displacement under the movement of the accelerator pedal 11, or generates a braking displacement under the movement of the brake pedal 21; the pedal feel control component 4 is electrically connected to the accelerator pedal 11 through the accelerator switch 12, the pedal feel control component 4 is electrically connected to the brake pedal 21 through the brake switch 22, and the displacement component 3 is connected to the pedal feel control component 4, and according to the opening and closing information of the accelerator switch 12 and the brake switch 22, the pedal feel control component 4 generates an accelerator pedal feel corresponding to the accelerator pedal 11, or a brake pedal feel corresponding to the brake pedal 21.

[0039] In the vehicle acceleration and braking system provided in the embodiment of the present application, the displacement components 3 are connected to the accelerator pedal 11 and the brake pedal 21. According to the opening and closing information of the accelerator switch 12 and the brake switch 22, the pedal feel control component 4 generates an accelerator pedal feel corresponding to the accelerator pedal 11, or a brake pedal feel corresponding to the brake pedal 21. At this time, the accelerator pedal 11 and the brake pedal 21 only need a set of displacement components 3 and pedal feel control components 4 devices, and then with the opening and closing information of the accelerator switch 12 and the brake switch 22, the driver's acceleration and braking needs can be sensed.

[0040] In the related art, in order to sense the acceleration and braking needs of the driver, it is necessary to set up a set of acceleration displacement component 3 and acceleration pedal feel control component device and a set of braking displacement component 3 and brake pedal feel control component device, that is, to set up two sets of devices to achieve it. However, the present application only needs to set up an acceleration switch 12 and a brake switch 22. According to the opening and closing information of the acceleration switch 12 and the brake switch 22, the accelerator pedal 11 and the brake pedal 21 can sense the acceleration and braking needs of the driver only through a set of displacement component 3 and pedal feel control component 4 devices, thus reducing the development cost.

[0041] The specific process is as follows: when the driver steps on the accelerator pedal 11, the displacement component 3 generates an acceleration displacement under the movement of the accelerator pedal 11. At the same time, according to the opening and closing information of the accelerator switch 12 and the brake switch 22, the pedal feel control component 4 generates an accelerator pedal feel corresponding to the accelerator pedal 11 to sense the driver's acceleration demand. Similarly, when the accelerator steps on the brake pedal 21, the displacement component 3 generates a braking displacement under the movement of the brake pedal 21. At the same time, according to the opening and closing information of the accelerator switch 12 and the brake switch 22, the pedal feel control component 4 generates a brake pedal feel corresponding to the brake pedal 21 to sense the driver's braking demand.

[0042] Here, it should be explained that the accelerator pedal 11 is also called the gas pedal. The accelerator pedal 11 is a mechanical structure. When the driver steps on the accelerator pedal 11, the accelerator pedal 11 can transfer the force of the driver's stepping to the displacement component 3. The principle of transmission can be the lever principle, so that the displacement component 3 produces an accelerated displacement. The accelerator pedal 11 can be a floor-type pedal, that is, the rotating shaft is located at the bottom of the pedal, the driver's sole can be completely stepped on the pedal, and the pedal itself provides a fulcrum, the calf and ankle can easily control the pedal, which improves the accuracy of controlling the pedal under the foot and reduces fatigue. In addition, the accelerator pedal 11 can also be a suspended pedal, that is, the rotating shaft is located at the top of the bracket, the lower side structure is simple, and the stepping is lighter and cost-saving. The embodiment of the present application does not limit the type of the accelerator pedal 11. In an implementable method provided in the embodiment of the present application, the accelerator pedal 11 is a floor-type pedal.

[0043] Similarly, it needs to be explained that the brake pedal 21 is a pedal that limits power. The brake pedal 21 is also a mechanical structure. When the driver steps on the brake pedal 21, the brake pedal 21 can transfer the force stepped on by the driver to the displacement component 3. The principle of transmission can be the lever principle, so that the displacement component 3 produces a braking displacement. Similarly, the brake pedal 21 can be a floor-type pedal, that is, the shaft is located at the bottom of the pedal, the driver's sole can be completely stepped on the pedal, and the pedal itself provides a fulcrum, the calf and ankle can easily control the pedal, which improves the accuracy of the pedal control under the foot and reduces fatigue. In addition, the brake pedal 21 can also be a suspended pedal, that is, the shaft is located at the top of the bracket, the lower side structure is simple, the stepping is lighter and cost-saving. The embodiment of the present application does not limit the type of the brake pedal 21. In order to be consistent with the type of the accelerator pedal 11, in an implementable manner provided in the embodiment of the present application, the brake pedal 21 is a floor-type pedal.

[0044] Specifically, refer to Figure 1 The accelerator switch 12 and the brake switch 22 are used to confirm whether the accelerator pedal 11 and the brake pedal 21 are pressed. Different electrical signals can be generated when the accelerator pedal 11 and the brake pedal 21 are pressed or not. According to the different electrical signals, the pedal feel control component 4 generates an accelerator pedal feel corresponding to the accelerator pedal 11, or a brake pedal feel corresponding to the brake pedal 21.

[0045] In addition, the displacement assembly 3 may include a cylinder body and a piston, the pistons are connected to the accelerator pedal 11 and the brake pedal 21, the cylinder body is formed with a receiving chamber, a liquid is arranged in the receiving chamber, and the piston is slidably connected to the cavity wall of the receiving chamber. When the accelerator pedal 11 is stepped on, the piston generates an acceleration displacement under the movement of the accelerator pedal 11, and when the brake pedal 21 is stepped on, the piston generates a braking displacement under the movement of the brake pedal 21. Here, it should be supplemented that when both the accelerator pedal 11 and the brake pedal 21 are not stepped on, the piston displacement in the master cylinder is 0, that is, the displacement amount is 0, and the pedaling movement (depth) of the accelerator pedal 11 and the brake pedal 21 are both 0.

[0046] Further, refer to Figure 1 The pedal feel control component 4 includes a pedal feel controller 41 and a pedal feel simulator 42. The pedal feel controller 41 is electrically connected to the accelerator pedal 11 through the accelerator switch 12. The pedal feel controller 41 is electrically connected to the brake pedal 21 through the brake switch 22. The pedal feel simulator 42 is connected to the displacement component 3. The pedal feel controller 41 is electrically connected to the pedal feel simulator 42. According to the opening and closing information of the accelerator switch 12 and the brake switch 22, the pedal feel controller 41 controls the pedal feel simulator 42 to adjust to the accelerator pedal feel corresponding to the accelerator pedal 11, or the brake pedal feel corresponding to the brake pedal 21.

[0047] The specific process is as follows: when the driver steps on the accelerator pedal 11, the piston generates an acceleration displacement under the movement of the accelerator pedal 11, and at the same time, according to the opening and closing information of the accelerator switch 12 and the brake switch 22, the pedal feel controller 41 controls the pedal feel simulator 42 to adjust to the accelerator pedal feel corresponding to the accelerator pedal 11. Similarly, when the accelerator steps on the brake pedal 21, the displacement component 3 generates a braking displacement under the movement of the brake pedal 21, and at the same time, according to the opening and closing information of the accelerator switch 12 and the brake switch 22, the pedal feel controller 41 controls the pedal feel simulator 42 to adjust to the brake pedal feel corresponding to the brake pedal 21.

[0048] Here, it should be explained that the role of the pedal feel simulator 42 is to receive the requirements of the pedal feel controller 41 and change the damping to provide different pedal feelings. The role of the pedal feel controller 41 is to obtain the driver's acceleration requirements according to the opening and closing information of the accelerator switch 12 and the brake switch 22, and adjust the pedal feel simulator 42.

[0049] Furthermore, refer to Figure 1 The pedal feel control component 4 includes a displacement sensor 43, which is electrically connected to the pedal feel controller 41. The displacement sensor 43 is connected to the displacement component 3, and is used to obtain the displacement generated by the displacement component 3 and transmit the displacement to the pedal feel controller 41.

[0050] The specific process is as follows: when the driver steps on the accelerator pedal 11, the piston generates an acceleration displacement under the movement of the accelerator pedal 11, and the acceleration displacement is collected by the displacement sensor 43, and the displacement sensor 43 transmits the collected acceleration displacement to the pedal feel controller 41. At the same time, according to the opening and closing information of the accelerator switch 12 and the brake switch 22, the pedal feel controller 41 controls the pedal feel simulator 42 to adjust to the acceleration pedal feel corresponding to the accelerator pedal 11 according to the acceleration displacement collected by the displacement sensor 43. At the same time, the pedal feel controller 41 outputs the movement of the accelerator pedal 11 (such as depth) according to the acceleration displacement collected by the displacement sensor 43. Similarly, when the accelerator driver steps on the brake pedal 21, the displacement component 3 generates a braking displacement under the movement of the brake pedal 21, and the braking displacement is collected by the displacement sensor 43, and the displacement sensor 43 transmits the collected braking displacement to the pedal feel controller 41. At the same time, according to the opening and closing information of the accelerator switch 12 and the brake switch 22, the pedal feel controller 41 controls the pedal feel simulator 42 to adjust to the brake pedal feel corresponding to the brake pedal 21 according to the braking displacement collected by the displacement sensor 43. At the same time, the pedal feel controller 41 outputs the movement of the brake pedal 21 (such as depth) according to the braking displacement collected by the displacement sensor 43.

[0051] Here, it is necessary to explain that, if the displacement sensor 43 is a voltage sensor, the voltage sensor is a sensor that can sense the measured voltage and convert it into a usable input signal, that is, the voltage output by it changes with the change of the piston displacement, and the changed voltage is transmitted to the pedal feel controller 41; if the displacement sensor 43 is a sensor that can sense the measured current and convert it into an input signal, that is, the current output by it changes with the change of the piston displacement, and the changed current is transmitted to the pedal feel controller 41. The embodiment of the present application does not limit the type of the displacement sensor 43.

[0052] In some embodiments provided in the present application, the opening and closing information of the acceleration switch 12 and the brake switch 22 includes three situations: both the acceleration switch 12 and the brake switch 22 are opened, one of the acceleration switch 12 and the brake switch 22 is closed, and the acceleration switch 12 and the brake switch 22 are closed. The situation that one of the acceleration switch 12 and the brake switch 22 is closed includes two situations, only the acceleration switch 12 is closed and the brake switch 22 is closed, that is, four situations.

[0053] The first case is that both the accelerator switch 12 and the brake switch 22 are turned on, that is, the driver does not need to accelerate or brake. At this time, the accelerator pedal 11 and the brake pedal 21 are not depressed, and the accelerator pedal 11 and the brake pedal 21 do not move (depth is 0). At this time, the displacement of the piston is 0.

[0054] The second situation is that the accelerator switch 12 is closed, and the pedal feel control component 4 generates an accelerator pedal feel corresponding to the accelerator pedal 11. The specific process is: when the driver steps on the accelerator pedal 11, the piston generates an acceleration displacement under the movement of the accelerator pedal 11, and the acceleration displacement is collected by the displacement sensor 43, and the displacement sensor 43 transmits the collected acceleration displacement to the pedal feel controller 41. At the same time, the accelerator switch 12 is closed, and the electrical signal of the accelerator pedal 11 is transmitted to the pedal feel controller 41. The pedal feel controller 41 controls the pedal feel simulator 42 to adjust to the acceleration pedal feel corresponding to the accelerator pedal 11 according to the acceleration displacement collected by the displacement sensor 43. At the same time, the pedal feel controller 41 outputs the movement of the accelerator pedal 11 (such as depth) according to the acceleration displacement collected by the displacement sensor 43.

[0055] The third situation is that the brake switch 22 is closed, and the pedal feel control component 4 generates a brake pedal feel corresponding to the brake pedal 21. The specific process is: when the driver steps on the brake pedal 21, the displacement component 3 generates a brake displacement under the movement of the brake pedal 21, and the brake displacement is collected by the displacement sensor 43, and the displacement sensor 43 transmits the collected brake displacement to the pedal feel controller 41. At the same time, the brake switch 22 is closed, and the electrical signal of the brake pedal 21 is transmitted to the pedal feel controller 41. The pedal feel controller 41 controls the pedal feel simulator 42 to adjust to the brake pedal feel corresponding to the brake pedal 21 according to the brake displacement collected by the displacement sensor 43. At the same time, the pedal feel controller 41 outputs the movement (such as depth) of the brake pedal 21 according to the brake displacement collected by the displacement sensor 43.

[0056] The fourth situation is that the accelerator switch 12 and the brake switch 22 are closed. To ensure the driver's safety, the pedal feel control component 4 generates a brake pedal feel corresponding to the brake pedal 21. The specific process is: when the driver steps on the accelerator pedal 11 and the brake pedal 21, and the accelerator switch 12 and the brake switch 22 are both closed, the pedal feel controller 41 only obtains the electrical signal of the brake switch 22 being closed, and the control displacement component 3 only generates a braking displacement under the action of the brake pedal 21, and the braking displacement is collected by the displacement sensor 43, and the displacement sensor 43 transmits the collected braking displacement to the pedal feel controller 41. At the same time, the pedal feel controller 41 only obtains the braking displacement collected by the displacement sensor 43, and controls the pedal feel simulator 42 to adjust to the brake pedal feel corresponding to the brake pedal 21. At the same time, the pedal feel controller 41 outputs the movement (such as depth) of the brake pedal 21 according to the braking displacement collected by the displacement sensor 43.

[0057] Correspondingly, the present application also provides a control method for a vehicle acceleration and braking system to sense the acceleration and braking needs of the driver, referring to Figure 2 , the control method comprises:

[0058] Step S1: In response to the on / off information of the accelerator switch and the brake switch, the pedal feel control component generates an accelerator pedal feel corresponding to the accelerator pedal, or a brake pedal feel corresponding to the brake pedal.

[0059] Further, the on / off information of the accelerator switch and the brake switch includes the accelerator switch being closed or the brake switch being closed and the accelerator switch and the brake switch being closed. In order to clarify how the pedal feel control component generates an accelerator pedal feel corresponding to the accelerator pedal, or a brake pedal feel corresponding to the brake pedal, according to the on / off information of the accelerator switch and the brake switch, step S1 includes steps S11 to S13, referring to Figure 3 , specifically:

[0060] Step S11: In response to the accelerator switch being closed, the pedal feel control component generates an accelerator pedal feel corresponding to the accelerator pedal;

[0061] Step S12: In response to the brake switch being closed, the pedal feel control component generates a brake pedal feel corresponding to the brake pedal;

[0062] Step S13: In response to the accelerator switch and the brake switch being closed, the pedal feel control assembly generates a brake pedal feel corresponding to the brake pedal.

[0063] In step S13, when the accelerator switch and the brake switch are closed, the pedal feel control component assumes that the driver has a braking demand to improve the driver's safety factor.

[0064] Furthermore, the pedal feel control component includes a pedal feel controller and a pedal feel simulator, the pedal feel controller is electrically connected to the accelerator pedal via an accelerator switch, the pedal feel controller is electrically connected to the brake pedal via a brake switch, the pedal feel simulator is connected to the displacement component, and the pedal feel controller is electrically connected to the pedal feel simulator. In step S1, in response to the on / off information of the accelerator switch and the brake switch, the pedal feel control component generates an accelerator pedal feel corresponding to the accelerator pedal, or a brake pedal feel corresponding to the brake pedal, referring to Figure 4 , specifically:

[0065] Step S1: In response to the on / off information of the accelerator switch and the brake switch, the pedal feel controller controls the pedal feel simulator to adjust to the accelerator pedal feel corresponding to the accelerator pedal, or the brake pedal feel corresponding to the brake pedal.

[0066] Similarly, the opening and closing information of the accelerator switch and the brake switch includes the accelerator switch being closed or the brake switch being closed and the accelerator switch and the brake switch being closed. In order to clarify how, according to the opening and closing information of the accelerator switch and the brake switch, the pedal feel controller controls the pedal feel simulator to adjust to the accelerator pedal feel corresponding to the accelerator pedal, or, the brake pedal feel corresponding to the brake pedal, step S1 responds to the opening and closing information of the accelerator switch and the brake switch, and the pedal feel controller controls the pedal feel simulator to adjust to the accelerator pedal feel corresponding to the accelerator pedal, or, the brake pedal feel corresponding to the brake pedal, including steps S11 to S13, refer to Figure 5 , specifically:

[0067] Step S11: In response to the accelerator switch being closed, the pedal feel controller controls the pedal feel simulator to adjust to an accelerator pedal feel corresponding to the accelerator pedal;

[0068] Step S12: in response to the brake switch being closed, the pedal feel controller controls the pedal feel simulator to adjust to a brake pedal feel corresponding to the brake pedal;

[0069] Step S13: In response to the accelerator switch and the brake switch being closed, the pedal feel controller controls the pedal feel simulator to adjust to a brake pedal feel corresponding to the brake pedal.

[0070] Likewise, when the accelerator switch and the brake switch are closed, the pedal feel controller assumes that the driver has a braking demand to improve the driver's safety factor.

[0071] The above is only an implementation method of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
