Description

Technical Field

[0001] The present application relates to the field of seat technology, and in particular to a seat control system, method, controller, medium, program product and vehicle. Background Art

[0002] With the development of society, cars have become more and more popular as a means of transportation for people's daily travel. Seats are important components of cars. When people go out to drive or ride, they need to sit on seats. However, since people's body characteristics such as weight and appearance vary from person to person, the same seat is usually adjusted to a posture that suits them when people of different weights and appearances sit on it.

[0003] Most existing memory seats achieve automatic adjustment through passive adjustment, such as by sending commands from a mobile device to retrieve seat memory information or by using memory adjustment buttons. This adjustment method is inconvenient and lacks intelligence. Furthermore, most existing memory seats utilize Hall effect sensors with rigid structures. However, these sensors exhibit variability in output at different temperatures and are susceptible to electromagnetic interference. Furthermore, their rigid structure makes significant deformation difficult, limiting their usefulness. Significant sensor deformation can also damage the seat's internal electronic components.

[0041] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is particularly noted that the following embodiments are only used to illustrate the present application and do not limit the scope of the present application. Similarly, the following embodiments are only some embodiments of the present application and not all embodiments. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of such features. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise specifically defined. All directional indications in the embodiments of this application (such as up, down, left, right, front, back...) are only used to explain the relative positional relationship, movement, etc. between the components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. A process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0043] Reference herein to an "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it refer to independent or alternative embodiments that are mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0044] See also Figure 1 , Figure 1This is a structural schematic diagram of the first embodiment of the seat control system for a vehicle provided in this application. The seat control system 100 in this embodiment includes a flexible sensor module 120, a data processing and storage module 130 and a drive module 140 arranged on the supporting part of the seat 110.

[0045] The flexible sensor module 120 is used to collect the occupant's current pressure signal. The data processing and storage module 130 is connected to the flexible sensor module 120 and matches the occupant's current pressure signal with preset seat posture parameters. The drive module 140 is connected to the data processing and storage module 130 and adjusts the seat's posture based on the matched seat posture parameters.

[0046] It can be understood that the seat control system provided in this application can automatically match the seat posture parameters through the occupant's weight signal without the user's active operation, thereby improving the user's riding comfort and reducing the tediousness of manual seat adjustment, thereby improving the convenience of vehicle use.

[0047] Furthermore, in an embodiment of the present application, the seat 110 includes a cushion area and a backrest area, and the cushion area and the backrest area are respectively installed with a flexible sensor module 120, and the flexible sensor module 120 of the present application includes a plurality of flexible sensors, which are evenly distributed in the cushion area, the backrest area and the headrest area of the seat 110, and can be 2, 4, 6... etc., and the present application does not limit the specific quantity. Among them, the flexible sensor module 120 in the cushion area is used to collect the current pressure signal of the occupant's buttocks, and the flexible sensor module 120 in the backrest area is used to collect the current pressure signal of the occupant's back. In other embodiments, the headrest area can also be installed with a flexible sensor module 120 to collect the current pressure signal of the occupant's head to assist in the judgment of the pressure signals of the cushion area and the backrest area. It can be understood that through this multi-point distributed layout, the weight of the occupant can be identified more accurately.

[0048] Specifically, the flexible sensor in the flexible sensor module 120 of the present application is a flexible piezoresistive strain gauge sensor. It can change the conductive pathway within the flexible sensor by applying pressure from the human body, inducing a change in current, thereby generating a differential signal. Specifically, the flexible sensor module 120 of the present application serves as the primary monitoring device for changes in human weight. It converts the human weight signal into a current signal. Specifically, a rated voltage is applied to generate a stable current. When an occupant enters a seat, they apply pressure to the seat cushion and backrest, causing the conductive pathway within the flexible sensor to change, increasing resistance. The current signal representing the measured occupant's weight is obtained by calculating the formula I = U / R. Conventional Hall sensors generate differential signals by varying the strength of the magnetic field, creating a difference in the Hall voltage across the semiconductor. However, Hall sensors exhibit temperature variability and are susceptible to electromagnetic interference. Therefore, compared to conventional Hall sensors, the use of a flexible sensor in this embodiment not only avoids the temperature variability and susceptibility to electromagnetic interference, but also prevents damage to the electronic components within the device due to the rigid structure of the Hall sensor.

[0049] Furthermore, the data processing and storage module 130 of the present application is pre-configured with at least one set of seat posture parameters and corresponding preset pressure characteristic information. The seat posture parameters include at least one or a combination of the following: the fore-and-aft slide distance of the seat, the seatback tilt angle, and the seat height. The preset pressure characteristic information includes a preset pressure signal and a preset pressure characteristic value.

[0050] Optionally, when it is determined that the current pressure signal matches the preset seat posture parameters, the data processing and storage module 130 generates a seat adjustment instruction based on the matching preset seat posture parameters and gives it to the drive module 140. The drive module 140 can further adjust the current posture of the seat according to the adjustment instruction, such as adjusting the seat height, the inclination of the backrest, the amount of movement of the seat forward, backward, left and right, etc., so that the current sitting posture of the seat is more suitable for the occupant and the ride is more comfortable.

[0051] Compared with the prior art, there is no need for passengers to manually adjust the seat, which improves the convenience of seat adjustment and makes the seat control system 100 in this embodiment more intelligent.

[0052] It will be appreciated that the present application implements vehicle start assist monitoring by setting threshold pressure information representing occupant weight information. Specifically, the preset pressure characteristic information in the data processing and storage module 130 includes a preset pressure signal and a preset pressure characteristic value, and the preset pressure signal also includes a threshold pressure signal. By setting the threshold pressure signal, vehicle users can be monitored to prevent underage driving and non-owner driving of the vehicle.

[0053] The following describes this application solution in conjunction with specific application scenarios:

[0054] 1. Underage Driving Warning

[0055] When a occupant sits in the seat, the flexible sensor module 120 receives the current pressure signal generated by the occupant, which includes the occupant's current hip pressure signal and current back pressure signal. Both the current hip pressure signal and the current back pressure signal reflect the occupant's weight information. Therefore, for a family vehicle, the user can use the weight of a minor in the family (e.g., 40 kg) as a reference to set a threshold pressure signal corresponding to the weight information and store it in the data processing and storage module 130. When a minor sits in the driver's seat, the flexible sensor module 120 in the seat cushion area receives the current hip pressure signal and compares it with the threshold hip pressure signal stored in the data processing and storage module 130. If the hip pressure signal is less than the threshold, indicating that the occupant's current weight is less than the threshold weight, the occupant is a minor. At this point, the data processing and storage module 130 generates a vehicle lock command, preventing the vehicle from starting, thereby preventing dangerous driving behavior by minors.

[0056] In actual applications, when the occupant's current pressure signal is less than the threshold pressure signal, the data processing and storage module 130 can also send a reminder message to the car owner's mobile terminal to warn the car owner of underage driving.

[0057] 2. Non-driver intentional driving reminder

[0058] Furthermore, as described above, when the current pressure signal is greater than or equal to the threshold pressure signal, although it indicates that the occupant is not a minor and will not engage in dangerous driving behavior by a minor, the occupant may still be driving without the vehicle owner's authorization. Therefore, in this case, further confirmation is required, which is divided into the following situations:

[0059] (1) The data processing and storage module 130 further processes the current pressure signal to obtain the current pressure characteristic value, and further matches the current pressure characteristic value with the preset pressure characteristic value. If they match, the data processing and storage module 130 calls the seat posture parameter corresponding to the preset pressure characteristic value information to generate a seat adjustment instruction to the drive module 140, so that the seat drive module adjusts the seat to the preset position based on the adjustment instruction.

[0060] (2) When the current pressure signal is greater than or equal to the threshold pressure signal, and the sum of the number of mismatches between the current pressure signal and the preset pressure signal and the number of mismatches between the current pressure characteristic value and the preset pressure characteristic value is greater than or equal to the preset matching threshold, the data processing and storage module generates the vehicle owner confirmation information.

[0061] (3) When the total matching degree formed by the matching degree of each parameter of the current pressure signal with the corresponding parameter of the preset pressure signal, and the matching degree of each parameter in the current pressure characteristic value with the corresponding parameter in the preset pressure characteristic value is less than or equal to the preset matching ratio, the data processing and storage module generates the vehicle owner confirmation information.

[0062] In other words, when the current pressure signal is greater than or equal to the threshold pressure signal, while underage driving can be ruled out, further determination is needed based on the aforementioned parameters to determine whether the vehicle was driven by someone other than the driver. If this is not the driver's intention, the data processing and storage module 130 will generate an owner confirmation message, which will send a vehicle abnormality message to the owner's pre-set mobile terminal, restricting vehicle start. Of course, if the vehicle still needs to be started (requiring additional verification), a vehicle abnormality reminder message will be sent to the owner.

[0063] In this way, by detecting the weight signal of the occupant through the flexible sensor module arranged on the seat, and by setting the matching number or matching degree between the current pressure signal and the preset pressure signal, the current pressure characteristic value and the preset pressure characteristic value, it is possible to avoid the situation where a person who is not authorized by the owner drives the vehicle, thereby improving driving safety.

[0064] Please combine Figure 2 Describe the application scheme in detail, Figure 2 This is a flow chart of an embodiment of signal processing of a vehicle seat control system of the present application.

[0065] Optionally, the current pressure signal in the present application includes: a current hip pressure signal and a current back pressure signal, and the current pressure characteristic value processed by the data processing and storage module 130 includes:

[0066] a first ratio of the current back pressure signal to the current hip pressure signal; a second ratio of the first ratio to the current back pressure signal; and a third ratio of the first ratio to the current hip pressure signal.

[0067] Correspondingly, the preset pressure signals stored in the data processing and storage module 130 include a preset buttocks pressure signal and a preset back pressure signal, wherein the preset pressure characteristic values include:

[0068] A first preset ratio of the preset back pressure signal to the preset hip pressure signal; a second preset ratio of the first preset ratio to the preset back pressure signal; and a third preset ratio of the first preset ratio to the preset hip pressure signal.

[0069] Combine Figure 2 In the specific application scenario, the current pressure signal includes the current hip pressure signal A2 and the current back pressure signal B2, and the current pressure characteristic values include:

[0070] A first ratio X2 of the current back pressure signal B2 to the current hip pressure signal A2, ie, X2 = B2 / A2;

[0071] a second ratio Y2 of the first ratio X2 to the current back pressure signal B2, i.e., Y2 = X2 / B2;

[0072] A third ratio Z2 of the first ratio X2 to the current hip pressure signal A2, ie, Z2 = X2 / A2.

[0073] The preset pressure signals include a preset buttocks pressure signal A1 and a preset back pressure signal B1. The preset pressure characteristic values include:

[0074] a first preset ratio X1 of the preset back pressure signal B1 to the preset hip pressure signal A1, ie, X1 = B1 / A1;

[0075] a second preset ratio Y1 of the first preset ratio X1 to the preset back pressure signal B1, ie, Y1 = X1 / B1;

[0076] A third preset ratio Z1 of the first preset ratio X1 to the preset buttocks pressure signal A1 is Z1 = X1 / A1.

[0077] First, the current hip pressure signal A2 and the current back pressure signal B2 are collected by multiple flexible sensor modules 120 in the seat cushion area of the seat 110, and the data processing and storage module 130 calculates the ratio of the current hip pressure signal A2 to the current back pressure signal B2 as the first ratio X2, the ratio of the first ratio X2 to the current hip pressure signal A2 is calculated as the second ratio Y2, and the ratio of the first ratio X2 to the current back pressure signal B2 is calculated as the third ratio Z2.

[0078] To prevent dangerous driving behavior by minors, the current hip pressure signal A2 can be compared solely with a preset hip pressure signal A1. If the current hip pressure signal A2 is less than the preset hip pressure signal A1 (the preset hip pressure signal corresponding to the threshold weight), the driver is determined to be a minor and engaging in dangerous driving behavior, and the vehicle cannot be started. At this point, the judgment result can be further modified by comparing the current back pressure signal B2 with the preset back pressure signal B1 (the preset back pressure signal corresponding to the threshold weight). If the current back pressure signal B2 is less than the preset back pressure signal B1, the driver is further confirmed to be underage.

[0079] After ruling out underage driving, it is necessary to further determine whether the vehicle is being used by an authorized person. Specifically, the current hip pressure signal A2 and the current back pressure signal B2 generated when a non-owner's occupant or driver enters the seat are processed by the data processing and storage module 130 to obtain a first ratio X2, a second ratio Y2, and a third ratio Z2, respectively. These signals are then matched against a preset hip pressure signal A1, a preset back pressure signal B1, the first preset ratio X1, the second preset ratio Y1, and the third preset ratio Z1. If the number of mismatches is greater than or equal to a preset matching threshold, the driver is deemed to be driving the vehicle without their prior authorization. In the embodiment of the present application, the preset matching threshold is set to 4, that is, the current hip pressure signal A2 and the current back pressure signal B2, the first ratio X2, the second ratio Y2 and the third ratio Z2, respectively, with the preset hip pressure signal A1, the preset back pressure signal B1, the first preset ratio X1, the second preset ratio Y1 and the third preset ratio Z1, when the number of unmatched groups is greater than or equal to 4, it will be judged as not the driver's intention to drive the vehicle. At this time, the owner's confirmation information and the weight abnormality signal are sent to the owner's mobile device terminal as a warning.

[0080] In other embodiments of the present application, the degree of matching between various parameters can also be used to confirm whether the driver is driving unintentionally. Specifically, when the current pressure signal is greater than or equal to the threshold pressure signal, the current pressure signal is greater than or equal to the threshold pressure signal, and the total matching degree formed by the matching degree of each parameter of the current pressure signal with the corresponding parameters of the preset pressure signal, and the matching degree of each parameter in the current pressure characteristic value with the corresponding parameters of the preset pressure characteristic value, is less than or equal to the preset matching ratio, the data processing and storage module 130 generates the vehicle owner confirmation information.

[0081] Specifically, if it is judged that the total matching degree between the parameters corresponding to the above-mentioned current pressure signal (current hip pressure signal and current back pressure signal) and the current pressure characteristic value (first ratio, second ratio, third ratio) and the preset pressure signal (preset hip pressure signal and preset back pressure signal) and the pressure characteristic value (first preset ratio, second preset ratio, third preset ratio) is less than or equal to the preset matching ratio, for example, when it is 5% in this application, it is determined to be an act of driving without the authorization of the vehicle owner. At this time, an abnormal weight signal will be sent to the vehicle owner's mobile device terminal as a warning, and the vehicle start restriction function will be triggered.

[0082] Conversely, if the number of correct matches of the above signals is greater than or equal to the preset number of matching groups (e.g., greater than or equal to 4 groups) or the matching degree is greater than the preset matching ratio, it indicates that the current pressure signal and the current pressure characteristic value match the preset pressure signal and the preset pressure characteristic value, respectively. After a successful match, the data processing and storage module 130 generates seat adjustment instructions based on the matched seat posture parameters and sends them to the seat drive module. The drive module can further adjust the current seat posture according to the adjustment instructions, such as adjusting the seat height, backrest tilt, and seat movement, so that the current seat position information is more suitable for the occupant, making the ride more comfortable without the need for manual adjustment by the occupant.

[0083] The seat control system provided in the present application monitors the current pressure signal of the occupant's weight in real time through a flexible sensor module arranged on the seat, and then matches the current pressure signal with preset seat posture parameters, so that the seat can automatically adjust the current posture information based on the matching result. There is no need for the occupant to automatically adjust the seat, thereby improving the user's riding comfort and reducing the tediousness of manual seat adjustment, thereby improving the convenience of vehicle use.

[0084] In addition, in another implementation scenario of the present application, if the seat posture is adjusted by someone else, when the occupant wants to restore the original seat posture parameters, he or she only needs to enter the seat 110. The flexible sensor module 120 will collect the front hip pressure signal and the current back pressure signal. The data processing and storage module 130 will calculate the first ratio X2, the second ratio Y2, and the third ratio Z2, and match the above signals with the preset signals. After the match is correct, the data processing and storage module 130 sends a seat adjustment instruction to the drive module 140, and the seat is automatically adjusted to the initial position without sending instructions to the physical or virtual button. In other words, the seat control system of the present application can quickly match the occupant's weight signal when the occupant enters the seat, triggering the seat memory function.

[0085] Please combine Figure 3 , Figure 3 This is a structural schematic block diagram of another embodiment of the seat control system of the present application. In this embodiment, the seat control system 100 also includes a trigger control module 150 connected to the data processing and storage module 130, which is used to receive user instructions and trigger the data processing and storage module 130 to call pre-stored seat posture parameters.

[0086] In a specific application scenario of the present application, the trigger control module 150 is a virtual button set on the central control screen. The memory seat posture is called up through the virtual button on the central control screen to increase the optional options.

[0087] The trigger control module of the present application can be applied in the following scenarios, such as changes in road conditions, such as from highway to mountain (unpaved road) to highway. When facing changes in road conditions, such as when driving at highway, the seat can be in a normal posture. However, if it reaches an unpaved road in the mountains, in order to obtain a better driving vision, the seat posture may be adjusted, such as temporarily adjusting the backrest angle, the front and rear distance of the seat, etc. However, after this journey is over, if the occupant wants to restore to the original seat posture, he can actively trigger it through the virtual button on the central control screen, so that the data processing and storage module 130 calls the pre-stored seat posture parameters, so that the seat quickly returns to the preset posture.

[0088] Optionally, the trigger control module 150 of the present application can also be a seat button set on the side of the seat body. After the occupant adjusts the seat through the seat adjustment button, the data processing and storage module 130 records and stores the posture information corresponding to the position of the seat 110, such as the height position information of the seat 110, the inclination angle information of the backrest, etc., and uses this information as the preset seat posture parameters.

[0089] In addition, when the driver or passenger uses the vehicle for the first time, it is also necessary to collect the preset pressure signal and pressure characteristic value of the authorized driver or passenger and associate them with the corresponding seat posture parameters. Specifically, the flexible sensor module 120 also collects the preset pressure signal of the occupant, and the seat button is used to accept the adjustment operation of the occupant to make the seat 110 assume the preset posture. The data processing and storage module 130 uses the posture parameters corresponding to the preset posture as the preset seat posture parameters and associates them with the preset pressure signal of the occupant collected by the flexible sensor module 120. In this way, the weight information of all authorized personnel in the vehicle can be bound to the corresponding seat parameters. In this way, as long as the driver or passenger takes a seat, the corresponding seat posture parameters can be automatically identified and matched based on the weight, triggering automatic seat adjustment, that is, passive triggering, without the need for manual operation by the occupant.

[0090] In the embodiments of this application, a combination of passive and active triggering modes enables rapid switching between different memory positions to meet personalized needs. In passive triggering mode, after the user takes a seat, the system automatically identifies and quickly returns to the preset seat position based on flexible sensors, eliminating the need for manual operation and achieving "senseless adjustment." This is particularly suitable for daily high-frequency use scenarios, saving adjustment time. Active triggering mode gives users the freedom to choose independently. In scenarios such as multiple people sharing a vehicle or requiring temporary adjustments, users can quickly switch between different memory positions using virtual or physical buttons on the central control panel to meet personalized needs.

[0091] Furthermore, the two triggering methods complement each other, preventing functional inactivity due to a single trigger failure. If the passive triggering mode temporarily fails due to sensor failure or signal interference, the user can still complete seat adjustment through active triggering. Conversely, if the active triggering module fails (such as a button failure), passive triggering can still maintain basic automatic seat adjustment functionality, ensuring system stability.

[0092] Please combine Figure 4 , Figure 4 This is a structural schematic block diagram of another embodiment of the seat control system of the present application. In this embodiment, the seat control system 100 further includes a seat belt detection module 160 that is communicatively connected to the information processing module. The seat belt detection module 160 is used to monitor the use of the seat belt based on the current pressure signal of the occupant and the vehicle speed.

[0093] In the present application, the seat belt detection module 160 may include a seat belt 161 and a seat belt buckle state sensor 162. The seat belt buckle state sensor 162 is used to detect the use state of the seat belt 161. In the present application, the data processing and storage module 130 generates a reminder message when it is obtained that the current driving speed of the vehicle is greater than or equal to the threshold speed and the seat belt buckle state sensor 162 detects that the seat belt 161 is in an unused state.

[0094] Please further combine Figure 5 5 is a schematic block diagram of an embodiment of seatbelt usage status detection according to the present application. Optionally, after the vehicle starts, an occupant enters the seat, causing a change in current in the flexible sensor module 120 on the seat 110. This means that the flexible sensor collects the occupant's current pressure signal and transmits it to the data processing and storage module 130. In this embodiment, the flexible sensor can be used to detect in real time whether an occupant is seated. If there is an occupant in the front row, the data processing and storage module 130 further obtains the vehicle's current speed. If the vehicle's current speed is greater than or equal to a threshold speed, such as 20 km / h, the vehicle is considered to be in motion, and the seatbelt reminder function is activated. At this point, the data processing and storage module 130, in conjunction with the seatbelt buckle status sensor 162, detects the feedback signal indicating the seatbelt usage status of the seatbelt 161 and determines whether the occupant is wearing a seatbelt. If it is detected that the occupant is not wearing a seatbelt and the vehicle is in motion, the data processing and storage module 130 generates a reminder, such as an audible or visual warning signal (dashboard indicator light, buzzer alarm, etc.) to remind the occupant to fasten their seatbelt.

[0095] It can be understood that this embodiment uses the flexible sensor on the seat body to sense the presence of the front seat occupant during vehicle driving, and further combines the seat belt buckle sensor to monitor the usage status of the seat belt, thereby realizing intelligent monitoring of the occupant's seat belt usage status and effectively improving driving safety.

[0096] Please further combine Figure 6 , Figure 6 This is a structural schematic diagram of another embodiment of the seat control system of this application, as shown in FIG. Figure 6 The seat control system 100 of the present application further includes a voice control module 170 for collecting the occupant's voice instructions and controlling the data processing and storage module 130 to call pre-stored seat posture parameters.

[0097] Optionally, during driving, the driver does not need to take his hands off the steering wheel or his eyes off the road, and can complete seat adjustment only through voice commands, such as "adjust the seat back a little straighter". After receiving the command, the voice control module 170 sends the command to the data processing and storage module 130. The data processing and storage module 130 calls the seat posture parameters that match the voice command, thereby realizing automatic adjustment of the seat, greatly reducing the risk of distraction caused by manual operation, and effectively improving driving safety. At the same time, voice control does not require precise touch buttons, which is more friendly to elderly users and users with limited mobility, further enhancing the convenience of operation.
