Referring to fig. 1 and 2, a first aspect of the present application provides a footpad 100 comprising an upper pad 1 and a lower pad 2. The base pad 2 and the upper pad 1 are stacked and in contact with the lower surface 12 of the base pad 2. The upper pad 1 further comprises an aperture 13 through its upper and lower surfaces 11, 12. The base pad 2 includes a receiving portion 21 recessed from the surface of the base pad 2 adjacent to the upper pad 1, the receiving portion 21 communicating with the aperture 13. Thus, dirt such as sediment and water on the surface of the upper mat 1 can enter the accommodating part 21 of the bottom mat 2 through the orifice 13, so that the dirt is prevented from remaining on the upper mat 1, and the appearance and the cleanliness of the foot mat 100 are prevented from being affected.

Referring to fig. 3, the increased number of apertures 13 facilitates the entry of dirt present on the upper surface 11 of the upper pad 1 into the receptacle 21. In addition, the upper pad 1 further includes a non-slip protrusion 15 provided on the upper surface 11, thereby increasing the friction between the sole of the user and the upper pad 1, and avoiding the situation that the sole of the user is wet or the upper surface 11 of the upper pad 1 is watery to cause slipping, affecting the user experience, or even causing injury to the user. Cleats 15 may also be provided on lower surface 12 to increase friction between upper mat 1 and base mat 2, avoiding relative sliding of upper mat 1 and base mat 2. The stud 15 is shown as triangular in shape, but it should be understood that the stud 15 may be of any shape and the application is not limited thereto. The stud 15 may extend 1-2 mm upwardly from the upper surface 11 to ensure a slip-resistant effect.

The upper pad 1 may further include a brush 14, where the brush 14 can help scrape dirt existing on the sole of the user, so that the dirt on the sole can enter the hole 13, and prevent the dirt from spreading when the user moves on the foot pad 100, thereby increasing the area of pollution. The brush 14 may be a fibrous brush 14 protruding upward from the upper surface 11, or may be a fibrous filament loop, as the application is not limited in this regard.

The foot pad 100 of the present application includes a dust suction motor 3 and a controller (not shown), which is electrically connected to the dust suction motor 3 for controlling the on or off of the dust suction motor 3. The base pad 2 includes a dust suction hole 22 and a dust suction duct (not shown): the dust suction hole 22 is provided at a side wall 23 of the accommodating portion 21, and the dust suction duct communicates with the accommodating portion 21 through the dust suction hole 22. The dust suction motor 3 communicates with the dust suction duct so as to communicate with the dust suction hole 22 and the accommodating portion 21 through the dust suction duct. When the controller controls the dust collection motor 3 to be turned on, the dust collection motor 3 can suck particulate matters such as dust, sand and the like in the accommodating part 21 into the dust collection pipeline, so that the cleaning of the foot pad 100 is kept, and the particulate matters are prevented from being lifted into the air when the foot pad 100 is vibrated or trampled. Thus, the foot pad 100 can complete the dust removal operation without the subsequent steps of taking out the foot pad 100 for brushing, so that the cleanliness of the foot pad 100 can be maintained in daily use, the artificial cleaning requirement and the cleaning frequency of the foot pad 100 can be reduced, and the user can avoid the trouble of cleaning the foot pad 100 regularly.

In some embodiments, the suction motor 3 may be used not only to adsorb particulate matter in the receptacle 21, but also to dry liquids present in the receptacle 21, since the suction generated by the suction motor 3 when in operation causes air to circulate in the receptacle 21. When the liquid exists in the sole of the user and enters the accommodating portion 21, the dust suction motor 3 can dry the liquid, thereby avoiding the problems of bacteria growth, mold and the like caused by the liquid remaining in the closed space of the vehicle for a long time.

Furthermore, the dust collection motor 3 and the accommodating part 21 are connected through the dust collection pipeline, so that the dust collection motor 3 is flexibly arranged, the dust collection motor 3 can be arranged at any suitable position, and then the communication between the dust collection motor 3 and the accommodating part 21 is realized through the pipeline arrangement.

In some embodiments, the footpad 100 includes a dust storage bin (not shown) connected to a dust extraction conduit that enables cleaning of the footpad 100 by drawing particulate matter from the receptacle 21 into the dust storage bin, which may be periodically emptied by a subsequent user to ensure proper operation of the dust extraction function of the footpad 100.

In other embodiments, the footpad 100 may further comprise a dust exhaust conduit 4. One end of the dust exhaust pipe 4 is connected with the dust suction motor 3, and the other end is communicated with the external space of the foot pad 100. By arranging the dust exhaust pipeline 4, the particulate matters sucked into the dust exhaust pipeline can be timely discharged out of the foot pad 100, the subsequent treatment of the particulate matters collected by the dust exhaust motor 3 by a user is not needed, and the frequency of participation of the user in cleaning is further reduced.

Referring to fig. 4 and 5, in some embodiments, the base mat 2 includes a spacer 25 and a plurality of receiving units 26. The accommodation unit 26 is provided in the accommodation portion 21. The spacers 25 space apart adjacent two receiving units 26. By providing the spacer 25, support can be provided for the upper pad 1 covering the upper pad 1 of the accommodating portion 21 in the third direction Z, so that the user can have a better contact feeling when stepping on the foot pad 100, the foot is prevented from sinking into the accommodating portion 21 when stepping on the upper pad 1 above the accommodating portion 21, and the upper pad 1 is deformed and tilted.

In some embodiments, the upper pad 1 is disposed in the receiving portion 21 and covers the receiving portion 21. The lower surface 12 of the upper pad 1 abuts the spacer 25. Thus, even if the user steps on any region of the upper mat 1, dirt on the upper surface 11 of the upper mat 1 can enter the accommodating part 21 through the orifice 13, and the need of manual brushing due to the sanitary dead angle of the upper mat 1 is avoided.

In some embodiments, the base pad 2 includes a plurality of dust extraction holes 22. The dust collection holes 22 are provided on the side wall 23 of the accommodating portion 21 perpendicular to the extending direction of the accommodating units 26, and the plurality of dust collection holes 22 are in one-to-one correspondence with the plurality of accommodating units 26. The suction duct communicates with a plurality of suction holes 22. Taking the embodiment shown in fig. 3 and 4 as an example, the accommodating unit 26 extends in the first direction X, and thus the dust suction hole 22 is provided at a sidewall 23 of the accommodating portion 21 perpendicular to the first direction X. Naturally, the accommodating unit 26 may be disposed along the second direction Y, and the dust suction hole 22 is disposed at a sidewall 23 of the accommodating portion 21 perpendicular to the second direction Y, which is not limited by the present application. By arranging the dust collection holes 22 in each containing unit 26 correspondingly, the dust collection motor 3 can clean dust substances in each containing unit 26, keep each containing unit 26 clean and avoid sanitary dead angles.

It is easy to understand that each dust suction hole 22 corresponds to a dust suction pipe, and a plurality of dust suction pipes can be independent from each other and respectively connected with the dust suction motor 3. Or a plurality of dust suction pipes may be integrated into one main dust suction pipe, which is connected to the dust suction motor 3, and the present application is not limited thereto.

In embodiments in which the plurality of suction ducts are independent of one another, the suction motor 3 may be configured with different winds for different suction ducts. For example, the center area of the footpad 100 is typically a tread area that is higher in tread frequency than, for example, the tread frequency at the edge of the footpad 100. If each dust collection pipeline has the same wind power, the wind power is too high at the accommodating unit 26 with less dust, so that energy consumption is wasted; in the case of the dust-rich accommodating unit 26, the wind may not be sufficient to efficiently perform dust collection. Therefore, the wind power of the dust suction duct corresponding to the accommodation unit 26 at the center of the foot pad 100 can be made larger than that of the other accommodation units 26, so that dust suction can be performed more pertinently while energy consumption can be reduced.

Referring to fig. 5-7 in combination, in some embodiments, the base pad 2 further includes a fluid aperture 27 disposed in the sidewall 23 of the receptacle 21. The footpad 100 further includes a first fluid reservoir 6, a second fluid reservoir 5, and a water pump 7. The water pump 7 is connected to the first fluid reservoir 6 and the second fluid reservoir 5, respectively. The first fluid storage portion 6 communicates with the accommodating portion 21 through the fluid hole 27 for storing unused fluid. The second fluid reservoir 5 communicates with the receiving portion 21 through a fluid hole 27 for storing contaminated fluid. The water pump 7 is electrically connected to a controller that can control the on and off of the water pump 7, and the operation mode of the water pump 7.

The footpad 100 includes a water-filled mode and a water-imbibed mode: when the foot pad 100 is in the water filling mode, the controller controls the water pump 7 to pump fluid from the first fluid reservoir 6 into the receptacle 21 through the fluid holes 27; when the footpad 100 is in the water-absorbing mode, the controller controls the water pump 7 to pump fluid from the receptacle 21 into the second fluid reservoir 5.

By this arrangement, the foot pad 100 can be automatically washed, and the dust, sewage, or the like remaining in the housing portion 21 can be further discharged out of the base pad 2 without manually washing, thereby further reducing the frequency of manually washing the foot pad 100. And because the foot pad 100 can be flushed independently, the enthusiasm and the frequency of flushing the foot pad 100 by a user are improved, so that the cleanliness and the cleanliness of the foot pad 100 are improved, and the health of the user is prevented from being influenced by bacterial breeding.

In addition, the foot pad 100 of the present application stores unused fluid and contaminated fluid separately, so that the liquid for each washing of the foot pad 100 is clean, thereby ensuring the cleanliness and sanitation of the washing.

The first fluid storage part 6 may contain clean tap water or fluid to which additives such as disinfectant and detergent are added, and the present application is not limited. By adding additives such as disinfectant to the fluid, the disinfection function can be achieved during the flushing process, further avoiding the growth of bacteria, mold and the like, and improving the sanitation level of the foot pad 100.

In some embodiments, the footpad 100 includes a drain conduit 8. One end of the drain pipe 8 is connected to the second fluid reservoir 5, and the other end communicates with the outer space of the foot pad 100. In this way, the foot pad 100 can automatically discharge the fluid in the second fluid storage portion 5 each time the foot pad 100 is flushed, or discharge the contaminated fluid when the volume of the contaminated fluid reaches the volume of the second fluid storage portion 5, without the need for the user to empty the second fluid storage portion 5, thereby further improving the degree of automation of the cleaning of the foot pad 100.

In the embodiment in which the plurality of spacers 25 and the plurality of containing units 26 are provided in the containing portion 21, the number of the fluid holes 27 includes a plurality, the fluid holes 27 are provided on the side wall 23 of the containing portion 21 perpendicular to the extending direction of the containing units 26, and the plurality of the fluid holes 27 are in one-to-one correspondence with the plurality of containing units 26, so that flushing of each containing unit 26 can be achieved. Furthermore, since the presence of the spacer 25 reduces the liquid volume of the accommodating portion 21 compared to a solution without the spacer 25 and the accommodating unit 26, the amount of liquid required to fill the entire accommodating portion 21 is reduced, and thus the liquid requirement for flushing the accommodating portion 21 is reduced, thereby reducing the cost of flushing the footpad 100 and the frequency of replenishing the fluid in the first fluid store.

Referring specifically to fig. 5, in the embodiment in which the upper mat 1 is disposed on the receiving portion 21 and covers the receiving portion 21, the height H1 of the sidewall 23 of the receiving portion 21 is greater than the sum of the thickness H2 of the upper mat 1 and the height H3 of the spacer 25, so that when the water pump 7 injects fluid into the receiving portion 21, the fluid can submerge the upper mat 1 without overflowing the receiving portion 21, thereby achieving synchronous cleaning of the upper mat 1, and further improving the cleanliness and hygiene of the foot mat 100.

Indeed, in embodiments in which the water pump 7 is not provided, it is also possible to set the height H1 of the side wall 23 of the housing 21 to be greater than or equal to the sum of the thickness H2 of the upper mat 1 and the height H3 of the spacer 25, thereby enabling the upper mat 1 to be fixed in the housing 21 in the first direction X and the second direction Y, avoiding the relative movement of the upper mat 1 and the base mat 2.

In some embodiments, the foot pad 100 includes only the suction motor 3, in which case the foot pad 100 is capable of performing only a suction function. In other embodiments, the footpad 100 only includes the water pump 7, and the footpad 100 is only capable of performing a flushing function. In the preferred embodiment, however, the foot pad 100 includes both the suction motor 3 and the water pump 7 to perform both the suction and irrigation functions, maximizing the degree of automation of the cleaning of the foot pad 100.

Referring to fig. 7, in the embodiment in which the foot pad 100 includes both the suction motor 3 and the water pump 7, in order to prevent the waste of fluid caused by the fluid flowing out of the accommodating portion 21 through the suction holes 22 when the water pump 7 injects the fluid into the accommodating portion 21, the foot pad 100 further includes a baffle 9 and a baffle motor (not shown), and the baffle 9 is disposed in the suction duct 28; the baffle motor is electrically connected with the controller and the baffle 9 respectively. When the controller controls the water pump 7 to inject fluid into the accommodating portion 21, the controller controls the barrier motor to operate, and the state of the barrier 9 is as shown in (a) of fig. 7. The baffle motor keeps the baffle 9 parallel to the flow cross section of the suction duct 28, and at this time, even if the fluid reaches the suction duct 28, the fluid is blocked by the baffle 9, and it is difficult to further flow through the suction duct 28. When the controller controls the dust suction motor 3 to operate, the controller turns off the control of the motor, and the shutter 9 is in an unstressed state at this time, so that when there is wind flowing in the dust suction duct 28, the shutter 9 pivots away about the rotation shaft 91 so that the dust suction duct 28 becomes in a flowable state, and the state of the shutter 9 is as shown in (b) of fig. 7.

In order for the baffle 9 to be able to effectively block the passage of fluid, in some embodiments the baffle 9 has the same shape and area as the flow cross-section of the suction duct 28, so that when the baffle motor is in operation, the baffle 9 seals the flow cross-section of the suction duct 28 as much as possible, blocking the passage of fluid.

In some embodiments, in order to further improve the sealing performance of the baffle 9, a sealing member may be provided at the edge where the baffle 9 contacts the inner wall of the dust suction pipe 28, for example, a rubber ring or the like is provided around the baffle 9, which is not limited by the present application.

In some embodiments, the fluid hole 27 and the dust suction hole 22 are provided at the opposite side walls 23 of the receiving part 21, respectively, so that the structure can be simplified. In addition, in the embodiment provided with the accommodating unit 26, the fluid hole 27 and the dust collection hole 22 are arranged opposite to each other, so that the flow area of the fluid hole 27 and the dust collection hole 22 is as close to the sectional area of the accommodating unit 26 as possible, and the dust collection efficiency and the flushing efficiency are improved.

Further, it is easily understood that if the lower edge of the dust collection hole 22 in the third direction Z is higher than the bottom wall 24 of the accommodating portion 21, there is a stepped position at the side wall 23 where the dust collection hole 22 is provided, and dust in the accommodating portion 21 is easily accumulated at the stepped position to be difficult to enter into the dust collection hole 22, forming a sanitary dead angle. If the lower edge of the dust suction hole 22 in the third direction Z is lower than the bottom wall 24 of the accommodating portion 21, the effective dust suction area is smaller than the flow area of the dust suction hole 22, reducing the dust suction efficiency. Therefore, referring to fig. 5, in the embodiment of the present application, the lower edge of the dust collection hole 22 in the third direction Z is flush with the bottom wall 24 of the accommodating portion 21. Similarly, the lower edge of the fluid hole 27 in the third direction Z may be flush with the bottom wall 24 of the accommodating portion 21, and will not be described here.

Referring to fig. 8, a second aspect of the present application provides a vehicle 200 comprising a footpad 100 as in any of the previous embodiments and a vehicle 200 control unit 210. Because the parts such as the water pump 7, the dust collection motor 3, the first fluid storage part 6, the second fluid storage part 5 and the like of the foot pad 100 are all connected with the accommodating part 21 of the foot pad 100 through pipelines, a person skilled in the art can flexibly set the positions of the water pump 7, the dust collection motor 3, the first fluid storage part 6, the second fluid storage part 5 of the foot pad 100 in the vehicle 200 according to actual demands and spaces, so that the structures such as the water pump 7, the dust collection motor 3 and the like are prevented from being intuitively seen by a user, and the aesthetic property of the vehicle 200 is influenced.

It should be noted that the vehicle may be an automobile, a passenger car, and a train for carrying personnel; trucks for carrying cargo, and the like, the application is not limited. And in the embodiment shown in the drawings, the arrangement positions of the water pump 7, the dust collection motor 3, the second fluid storage section 5 and the foot pad 100 are given as examples and not limitations, the foot pad 100 may be arranged under any seat in the vehicle 200, and the structures of the water pump 7, the dust collection motor 3 and the like may be arranged at any position in the vehicle 200, and the present application is not limited thereto.

Referring to fig. 9, a third aspect of the present application provides a self-cleaning method of a footpad, which can be applied to the footpad of the foregoing embodiments.

In step 301, the running state of the vehicle is acquired.

In this embodiment, the running state includes a running state, a braking state, so that an appropriate cleaning mode can be activated for different running states of the vehicle.

In step 302, it is determined whether the running state of the vehicle satisfies a preset condition, and if so, the foot pad is controlled to start a corresponding cleaning mode. In this way, it is possible to avoid that an improper cleaning mode is turned on when it is not desired or proper, thereby causing interference to a user or an error in the cleaning mode.

In one embodiment, the vehicle control unit determines whether the vehicle is in a driving state, and if so, controls the foot pad to open the dust collection mode. The dust collection mode is used for adsorbing particulate matters such as dust, sand and the like in the foot pad. Through the arrangement, in the running process of the vehicle, the foot pad keeps continuously absorbing dust, so that the dust absorbing function is completed in the running process, a user does not need to vacate time specially to absorb dust, and the cleaning efficiency and the use convenience are improved. Meanwhile, as the mechanical structure of the vehicle generates noise in the running process of the automobile, the sound generated during dust collection of the foot pad can be almost ignored, and the influence on driving is avoided.

In an embodiment, the vehicle control unit may further determine whether the vehicle is in a driving state, if not, control the foot pad to close the dust collection mode. Therefore, the foot pad can fully and automatically open and close the dust collection function without human intervention. Moreover, since the user may stay in the vehicle for a long time even when the vehicle is not started, such as waiting for an equal time or resting, turning off the dust collection mode at this time can avoid causing undesirable noise to the user.

In another embodiment, the vehicle control unit may also control the foot pad to turn off the dust collection mode after the dust collection mode has been continued for a while. For example, after the dust collection mode has been continued for five minutes, the dust collection mode is turned off. Therefore, as the particulate matters are not newly added in the foot pad after the dust collection mode is operated for a period of time, the cleanliness and the sanitation of the foot pad are not improved even if dust collection is continued, and the energy consumption can be avoided by setting the duration of the dust collection mode.

In some embodiments, the vehicle control unit may further record the number of times the vehicle is in a driving state, and after the number of times reaches a preset value, control the foot pad to start the dust collection mode. For example, when the vehicle is in the tenth driving state, the foot pad turns on the dust collection mode. Therefore, the dust collection mode can be prevented from being started in each driving process, and possible energy waste is avoided.

In other embodiments, the vehicle control unit may further determine whether the sound volume db in the vehicle cabin is greater than a preset value, and if so, control the foot pad to turn on the dust collection mode. Therefore, when the sound volume decibel in the cockpit is smaller than the preset value, the vehicle control unit defaults that the user is in a resting state or needs a quiet environment, and the foot pad is controlled to be closed in a dust collection mode, so that the quiet environment is provided for the user, and the cleaning intelligence of the foot pad is improved.

In another embodiment, the vehicle control unit determines whether it receives a cleaning command and whether the vehicle is in a braking state, if so, controls the foot pad to turn on the flush mode. The flush mode is used to flush the footpad. The braking state refers to a state in which the vehicle running speed is zero, i.e., a state in which it remains stationary. Where the vehicle may be in an ignition or flameout condition, the application is not limited. Because the liquid is required to be used in the flushing process, when the vehicle is in a braking state, the flushing mode is started, so that the liquid can be prevented from overflowing in the moving process of the vehicle, and further the pollution of the inner space of the vehicle cab is caused, or the body or clothes of a user are wetted. And the opening of the flushing mode requires the user to send a cleaning instruction, for example, a corresponding cleaning button on the vehicle is pressed, so that the user can ensure that the vehicle stops on a flat road surface and then the flushing mode is started, not only can the liquid in the foot pad be prevented from overflowing when the vehicle stops on an inclined plane, but also the flushing at unexpected time of the user and the interference to the user caused, for example, the user adjusts the vehicle to a braking state and hopes to rest in the vehicle, can be avoided.

In some embodiments, the flush pattern may include a water filling step and a water pumping step. The water injection step is as follows: liquid in the fluid reservoir of the vehicle is captured and injected into the footpad. The water pumping step is as follows: liquid in the foot pad is pumped out. The pumping step may pump fluid from the footpad into the fluid reservoir or may be direct to the exclusion of the vehicle, as the application is not limited. The water injection step and the water pumping step can be circulated for a plurality of times, so that the multiple flow of liquid and the impact of the liquid on the bottom wall and the side wall of the foot pad are realized in a limited foot pad space, and the flushing effect is simulated. In addition, in embodiments where the water filling step and the water pumping step are cycled multiple times, only a portion of the liquid in the footpad may be pumped out in multiple water pumping steps, so that the interior space of the footpad may be filled with a lesser amount of liquid in the next water filling step; and all liquid in the foot pad is pumped out in the last water pumping step, so that the residual liquid amount of the foot pad is minimized, the foot pad is easier to dry, and the problems that the foot pad is wet and bacteria, mould and the like are bred due to the fact that the residual liquid is more are avoided. For example, if the flush pattern includes four water injection steps and four water pumping steps, then the first, second and third water pumping steps each pump only a portion of the fluid in the footpad, and the fourth water pumping step pumps all of the fluid in the footpad.

Because the water filling step of the flushing mode of the foot pad needs to be obtained from the fluid storage part, in some embodiments, when the fluid in the fluid storage part is insufficient to complete one water filling step, or the fluid is insufficient during the water filling step, the vehicle control unit can control the vehicle to send out an alarm sound to report errors, or display a sign of insufficient fluid on the instrument panel or the vehicle-mounted television, so as to remind a user that the flushing mode cannot normally run. The warning sound may be a specific sound different from other warning sounds in the vehicle, thereby alerting the user that the cause of the error is due to an insufficient amount of liquid in the fluid reservoir so that the user can timely replenish the liquid.

In some embodiments, when the washing mode is started by the foot pad, and when the vehicle control unit judges that the vehicle is in a running state, if the washing mode is in the water injection step, the water injection step is stopped to enter the last water pumping step, and the washing mode of the foot pad is closed after the water pumping step is finished, so that water in the foot pad is prevented from overflowing when the vehicle is running; if the flushing mode is in the water pumping step, the current water pumping step is continuously completed, and then the flushing mode of the foot pad is closed, so that the situation that the flushing mode enters the next water injection step to cause overflow of liquid in the running process is avoided.

The number of water filling steps and water pumping steps can be set as desired by those skilled in the art, for example, the flushing mode can be cycled once, twice, or even ten water filling steps and water pumping steps, and the application is not limited. In some embodiments, the vehicle control unit may also control the footpad to turn on the air-dry mode after the end of the last water-pumping step, e.g., when the flush mode includes ten water-filling steps and ten water-pumping steps, the air-dry mode is turned on after the end of the tenth water-pumping step. The air-dry mode is used to air-dry the footpad. Through setting up the air-dry mode, can accelerate the dry progress of callus on sole, avoid being difficult to air-dry by oneself and lead to moist, peculiar smell, breeding the bacterium scheduling problem in the airtight space of vehicle. Furthermore, the duration of the air drying mode may be set as desired by those skilled in the art, for example, ten seconds, twenty seconds, one minute, etc., and the present application is not limited thereto.

In some embodiments, the vehicle control unit may further determine whether the humidity of the position of the foot pad is greater than a preset value, and if so, control the foot pad to open the air-drying mode, so that the air-drying mode can be intelligently opened when the air-drying is not thorough due to a greater ambient humidity and the like, and thus dryness of the foot pad is maintained. Similarly, the air-drying mode may also be default for a period of time, such as ten seconds, twenty seconds, one minute, etc., and the application is not limited.

Further, the vehicle control unit may control the foot pad to close the cleaning mode after the air-dry mode is ended. For example, if the duration of the air-dry mode is one minute, the vehicle control unit turns off the cleaning mode of the foot pad one minute after turning on the air-dry mode, so that the energy consumption of the vehicle can be saved, and meanwhile, the noise generated when the foot pad is operated for a long time in the vehicle braking state can be avoided to cause the interference to the user.

In some embodiments, after controlling the foot pad to close the cleaning mode, the vehicle control unit may also control the vehicle to make a sound, thereby prompting the user that the cleaning mode has ended, and the vehicle may be started and driven normally.

In addition, in the embodiment where the foot pad includes both the dust collection mode and the flushing mode, the vehicle control unit may control the foot pad to automatically turn on the flushing mode of the foot pad when the vehicle is in a braking state and is maintained for a preset time after a certain number of dust collection modes are performed. For example, after the foot pad performs the dust collection mode twice, the vehicle control unit automatically starts the washing mode of the foot pad as long as the vehicle control unit determines that the vehicle is in a braking state and is kept for three minutes. Therefore, the foot pad can automatically complete a dust collection mode and a flushing mode, and the foot pad can be kept in a clean state for a long time without human intervention. Meanwhile, the vehicle is in a braking state and is kept for a period of time, and then the flushing mode is started, so that the phenomenon that the foot pad is started by mistake when the vehicle gets on or off a traffic light or a passenger gets on or off the vehicle for a short time can be avoided.

It will be appreciated that in embodiments where the footpad is provided with both a dust extraction function and a flushing function, the self-cleaning method of the footpad may include the steps of the embodiments described above corresponding to the flushing function and the flushing function, and the application is not limited thereto.

To describe the technical solution of the present application in detail, as shown in fig. 10, the self-cleaning method of the foot pad may include:

In step 401, an operating state of the vehicle is acquired.

In this embodiment, the operating conditions include a braking condition and a driving condition, so that an appropriate cleaning mode can be activated for different operating conditions of the vehicle. When the running speed of the vehicle is greater than zero, the vehicle is in a running state. When the form speed of the vehicle is zero, the vehicle is in a braking state. The vehicle may be in an ignition state or a flameout state when the vehicle is in a braking state, and the present application is not limited.

In step 402, it is determined whether the running state of the vehicle is in a driving state, and if so, the foot pad is controlled to be turned on in the dust collection mode.

The dust collection mode is used for adsorbing particulate matters in the foot pad, so that the condition that the particulate matters exist in the foot pad to grow bacteria or dust is raised due to the fact that a user steps on the foot pad is avoided. In this embodiment, when the vehicle is in a running state, the foot pad keeps continuously sucking dust, the dust sucking function is completed in the running process of the vehicle, the user does not need to make special time for sucking dust, and the cleaning efficiency and the convenience of use are improved.

In step 403, it is determined whether the vehicle is in a driving state, if not, the foot pad is controlled to close the dust collection mode.

In this embodiment, the foot pad can be fully automatically turned on and off for the dust extraction function without human intervention. Moreover, because the user may stay in the vehicle for a long time even when the vehicle is not started, such as waiting for a person or rest, the dust collection mode is turned off at this time, so that undesirable noise to the user can be avoided, and the cleaning intelligence of the foot pad is improved.

In step 404, it is determined whether a cleaning command is received and whether the running state of the vehicle is in a braking state, if so, the foot pad is controlled to be in a flush mode.

The user in flush mode cleans the footpad. When the vehicle is in a flush mode, the vehicle control unit controls the footpad to take fluid from a fluid reservoir in the vehicle and to inject fluid into the footpad and then withdraw the fluid, thereby simulating the effect of the fluid flush. In this embodiment, the activation of the flushing mode when the vehicle is in a braked state can avoid that the vehicle causes spillage of liquid during movement, which in turn causes contamination of the interior space of the vehicle cabin, or wets the user's body or clothing. And the opening of the flushing mode requires the user to send a cleaning instruction, so that the user can start the flushing mode again when the vehicle is ensured to stop on a flat road surface, liquid overflow caused by the inclined state of the vehicle in the flushing process is avoided, and meanwhile, the foot pad can be prevented from flushing at an unexpected time of the user, so that the influence on the user is caused, for example, the user adjusts the vehicle to a braking state and hopes to rest in the vehicle.

In step 405, control of the footbed turns on the air-dry mode.

The air-dry mode is used to dry the footpad. In this embodiment, open the air-dry mode after the scour mode, can accelerate the dry progress of callus on the sole, avoid being difficult to air-dry by oneself and lead to moist, peculiar smell, breeding the scheduling problem of bacterium in the confined space of vehicle.

In step 406, control turns off the footbed in the air-dry mode.

In this embodiment, the cleaning mode of the foot pad is turned off after the air-dry mode is ended, so that energy consumption of the vehicle can be saved, and meanwhile, noise generated when the foot pad is operated for a long time in a vehicle braking state can be prevented from causing interference to a user.

It should be noted that, the dust collection mode and the flushing mode are started in no sequence, the vehicle control unit can start the corresponding cleaning mode according to the running state of the vehicle, for example, when the vehicle is in a braking state and the vehicle control unit receives a cleaning instruction, the flushing mode is started; after the flushing mode is finished, the vehicle control unit judges that the vehicle is in a running state, and at the moment, the dust collection mode is started, and the application is not limited.
