[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] The pedal assembly 10 according to an embodiment of the present invention will be described below with reference to the drawings.

[0033] Reference Figure 1 and Figure 2, the pedal assembly 10 according to the embodiment of the first aspect of the present invention comprises: a driver's floor 1, a pressure sensor and a control module, the driver's floor 1 has a brake pedaling area 11, the pressure sensor is arranged in the brake pedaling area 11, the pressure sensor is used to detect the pressure value of the brake pedaling area 11, the control module is connected to the pressure sensor, and the control module is used to brake the vehicle 100 according to the pressure value detected by the pressure sensor. For example, the control module can control the braking system of the vehicle 100 to brake the vehicle 100 when it is confirmed that the pressure value change exceeds the pressure value of 5N in the natural state, and the control module can also control the braking system of the vehicle 100 to brake the vehicle 100 when it is confirmed that the pressure value changes by 2N in 200ms.

[0034] By setting a brake pedal area 11 on the driver's seat floor 1 and setting a pressure sensor in the brake pedal area 11, the vehicle 100 can be braked through pressure changes, thereby realizing a braking method without pedal travel. Compared with the solution of setting an independent brake pedal on the driver's seat floor 1 for braking, this can avoid the risk of foreign objects falling between the pedal and the driver's seat floor 1 and causing the pedal to be unable to be stepped on, so that the vehicle 100 can be braked reliably, effectively ensuring the braking safety of the vehicle 100.

[0035] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, the brake pedal area 11 is raised toward the driving position of the vehicle 100. That is, the brake pedal area is raised from the driving position floor 1, which makes it easier for the user to identify the brake pedal area 11 and accurately step on the brake pedal area.

[0036] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, the surface of the brake pedal area 11 facing the driving position of the vehicle 100 is a pedal surface 12, and the angle between the normal direction of the pedal surface 12 and the length direction of the vehicle 100 is greater than or equal to 25° and less than or equal to 35°. That is, when the vehicle 100 is placed horizontally, the angle between the pedal surface 12 and the horizontal plane is greater than or equal to 25° and less than or equal to 35°. For example, the angle between the normal direction of the pedal surface 12 and the length direction of the vehicle 100 can be 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, or 35°.

[0037] When the user sits in the driver's seat and places his feet on the tread surface 12, the tread surface 12 can fit the sole of the user's foot more closely, so that the angle between the user's foot and calf is more labor-saving, meeting the user's requirements for high-quality riding experience. At the same time, the tread surface 12 is set to be at a certain angle with the horizontal plane. When foreign objects (for example, foreign objects can be water cups, mobile phones or wallets) fall onto the driver's seat floor 1, the foreign objects can be prevented from staying on the tread surface 12, so that the user can more reliably control the vehicle 100 to brake through the tread surface 12, thereby improving the safety performance of the vehicle 100.

[0038] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, the pressure sensor is disposed on the side of the brake pedal area 11 facing the cab of the vehicle 100, that is, the pressure sensor is disposed on the pedal surface 12. In this way, the pressure sensor can more sensitively and directly detect the force applied by the user in the brake pedal area 11, so that the detection result is more accurate, and the control module can react more sensitively to the pressure value detected by the pressure sensor to brake the vehicle 100, so that the vehicle 100 can brake more quickly and reliably, thereby improving the reliability of the vehicle 100 and improving the safety performance of the vehicle 100.

[0039] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, the driver's floor 1 can be elastically deformed in the brake pedaling area 11, and the pressure sensor is arranged on the side of the brake pedaling area 11 away from the cab of the vehicle 100. This can reduce the risk of the pressure sensor being damaged by long-term pedaling, so that the wiring harness of the pressure sensor can be arranged outside the cab, reducing the risk of the wiring harness of the pressure sensor being damaged, improving the reliability of the pressure sensor, extending the service life of the pressure sensor, and improving the reliability of the vehicle 100.

[0040] Reference Figure 2 According to a braking method according to an embodiment of the second aspect of the present invention, a vehicle 100 is braked using a pedal assembly 10 according to an embodiment of the first aspect of the present invention, and the braking method includes:

[0041] Recording the initial pressure value F1 when the driver initially steps on the brake pedal area 11;

[0042] Detecting the dynamic pressure value F2 when the brake pedal area 11 is subsequently stepped on;

[0043] Confirm that the difference between the dynamic pressure value F2 and the initial pressure value F1 is greater than or equal to the fluctuation value F3;

[0044] The vehicle 100 is braked.

[0045] When the user sits in the driving seat and places his feet on the tread surface 12, the initial pressure value F1 when the user initially steps on the brake pedal area 11 is recorded, and then the dynamic pressure value F2 when the brake pedal area 11 is subsequently stepped on is continuously detected. When the difference between the dynamic pressure value F2 and the initial pressure value F1 is less than the fluctuation value F3, the control system determines that the force applied by the user to the brake pedal area 11 is within the fluctuation range under the natural placement state, and does not brake the vehicle 100; when the difference between the dynamic pressure value F2 and the initial pressure value F1 is greater than or equal to the fluctuation value F3, the control system determines that the force applied by the user to the brake pedal area 11 exceeds the fluctuation range under the natural placement state, and determines that the user has applied a braking signal to the vehicle 100, and the control module controls the braking system of the vehicle 100 to brake the vehicle 100.

[0046] The difference between the dynamic pressure value F2 and the initial pressure value F1 is greater than or equal to the fluctuation value F3, including two situations: the dynamic pressure value F2 is greater than the initial pressure value F1 and the dynamic pressure value F2 is less than the initial pressure value F1; it should be understood that when the dynamic pressure value F2 is greater than the initial pressure value F1, it is the effect of the user applying force to the brake pedal area 11; when the dynamic pressure value F2 is less than the initial pressure value F1, it is the pressure value reduction caused by the user's foot leaving the brake pedal area 11, so that the vehicle 100 can be braked after the driver leaves the vehicle.

[0047] By using the pedal assembly 10 to brake the vehicle 100, the vehicle 100 can be braked by pressure changes, and a braking method without pedal travel can be realized, so that the vehicle 100 can be braked reliably, and the braking safety of the vehicle 100 can be effectively ensured;

[0048] At the same time, by confirming that the difference between the dynamic pressure value F2 and the initial pressure value F1 is greater than or equal to the fluctuation value F3, the vehicle 100 is braked. When the user applies light force to the brake pedal area 11 or moves slightly away from the brake pedal area 11, the vehicle 100 may not be braked, so that the user's foot can be placed in the brake pedal area 11 in a relatively relaxed manner, avoiding long-term force application on the brake pedal area 11 to cause user fatigue, thereby improving the overall performance of the vehicle 100; at the same time, this can reduce the risk of braking of the vehicle 100 due to changes in the force applied by the user to the brake pedal area 11 due to vibration of the vehicle 100, so that the vehicle 100 can be reliably braked using the above-mentioned braking method.

[0049] According to the braking method of the present invention, the vehicle 100 is braked by utilizing the pedal assembly 10, and the braking of the vehicle 100 can be achieved through pressure changes, thereby realizing a braking method without pedal travel, so that the vehicle 100 can be braked reliably, and the braking safety of the vehicle 100 can be effectively guaranteed, so that the user's feet can be placed in the brake pedal area 11 in a relatively relaxed manner, avoiding long-term force application on the brake pedal area 11 to cause user fatigue, thereby improving the overall performance of the vehicle 100.

[0050] Reference Figure 2 According to some embodiments of the present invention, before recording the initial pressure value when the driver initially steps on the brake pedaling area 11, the braking method further includes:

[0051] Confirm that the pressure value when the driver steps on the brake pedal area 11 is within a preset initial range; wherein the preset initial range is the pressure value range when drivers of different heights and weights put their feet on the brake pedal area 11 in a natural state. For example, the preset initial range can be collected in advance and stored in the control module.

[0052] When the user sits in the driving seat and places his feet on the tread surface 12, the pressure value of the driver when stepping on the brake pedal area 11 is detected. When the detected pressure value of the driver when stepping on the brake pedal area 11 is not within the preset initial range, it is judged as an abnormal driving state, and the control module does not perform braking operations on the vehicle 100 and does not activate the driving function of the vehicle 100; when the detected pressure value of the driver when stepping on the brake pedal area 11 is within the preset initial range, it is judged that the driver is in a normal driving state, and the pressure value is recorded as the initial pressure value F1.

[0053] In this way, the control module can generate different initial pressure values ​​F1 according to the height and weight of each driver. When a taller and heavier driver brakes the vehicle 100, it is not necessary to control the force to be smaller, so the taller and heavier driver does not need to precisely control the force applied; when a shorter and lighter driver brakes the vehicle 100, it is not necessary to apply a larger force to the brake pedal, so the shorter and lighter driver can save more effort when braking the vehicle 100, thereby enabling the vehicle 100 to achieve personalized braking matching and meet the user's demand for high-quality pedaling experience.

[0054] Reference Figure 2 According to some embodiments of the present invention, before braking the vehicle 100, the braking method further includes:

[0055] Confirm that the increase value F4 of the dynamic pressure value F2 in the preset time period T is greater than or equal to the preset difference value F5;

[0056] The preset difference value F5 is smaller than the fluctuation value F2. For example, the preset difference value F5 may be 2N.

[0057] When the difference between the dynamic pressure value F2 and the initial pressure value F1 is less than the fluctuation value F3, and when the increase value F4 of the dynamic pressure value F2 in the preset time period T is less than the preset difference F5, the control system determines that the force applied by the user to the brake pedal area 11 is within the fluctuation range in the natural placement state, and does not brake the vehicle 100; when the difference between the dynamic pressure value F2 and the initial pressure value F1 is less than the fluctuation value F3, and when the increase value F4 of the dynamic pressure value F2 in the preset time period T is greater than or equal to the preset difference F5, the control system determines that the rate of change of the force applied by the user to the brake pedal area 11 exceeds the rate of change of the fluctuation in the natural placement state, the control system determines that the user has applied a braking signal to the vehicle 100, and the control module controls the braking system of the vehicle 100 to brake the vehicle 100.

[0058] By detecting whether the increase value F4 of the dynamic pressure value F2 in the preset time period T is greater than or equal to the preset difference F5, it is determined whether the vehicle 100 needs to be braked. When a foreign object falls and hits the brake pedal area 11, the risk of the vehicle 100 being braked due to the instantaneous change of the force generated by the dynamic pressure value F2 caused by the falling of the foreign object can be reduced. The risk of the vehicle 100 being braked due to the change of the force applied by the user to the brake pedal area 11 due to the vibration of the vehicle 100 can be reduced, thereby improving the reliability of the vehicle 100.

[0059] In this way, whether the driver needs to brake the vehicle 100 can be judged by the change rate of the dynamic pressure value F2, and when it is confirmed that the driver needs to brake the vehicle 100, the vehicle 100 can be braked in time, thereby improving the response rate of the braking system and improving the overall performance of the vehicle 100.

[0060] Reference Figure 2According to some embodiments of the present invention, the preset time period is greater than or equal to 100ms and less than or equal to 300ms; for example, the preset time period may be 100ms, 110ms, 120ms, 130ms, 140ms, 150ms, 160ms, 170ms, 180ms, 190ms, 200ms, 210ms, 220ms, 230ms, 240ms, 250ms, 260ms, 270ms, 280ms, 290ms, or 300ms. The longer the preset time period is, the more effectively it can filter out the instantaneous change in the force generated by the dynamic pressure value F2 due to the falling of foreign objects, and the more effectively it can filter out the change in the force applied by the user to the brake pedal area 11 due to the vibration of the vehicle 100, and the more reliably the braking method can analyze whether the user needs to brake the vehicle 100; the shorter the preset time period is, the shorter the analysis time of the braking method in analyzing whether the user needs to brake the vehicle 100, and the more timely the vehicle 100 can be braked when it is necessary to brake the vehicle 100.

[0061] By setting the preset time period to be greater than or equal to 100ms and less than or equal to 300ms, the instantaneous change in the force generated by the dynamic pressure value F2 due to the falling of foreign objects and the change in the force applied by the user to the brake pedal area 11 due to the vibration of the vehicle 100 can be effectively filtered out, so that the braking method can quickly and reliably analyze whether the user needs to brake the vehicle 100, and reliably brake the vehicle 100 when braking is required.

[0062] Reference Figure 1-Figure 2 The vehicle 100 according to the third embodiment of the present invention comprises: the pedal assembly 10 according to the second embodiment of the present invention. For example, the vehicle 100 may be a car.

[0063] According to the vehicle 100 of the present invention, through the above-mentioned pedal assembly 10, the vehicle 100 can be braked through pressure changes, realizing a braking method without pedal travel, so that the vehicle 100 can be braked reliably and the braking safety of the vehicle 100 is effectively guaranteed.
