Abstract
Description
Technical Field
[0001] The present application relates to the technical field of vehicle-mounted equipment, and in particular to a seat, a seat control method, a smart cockpit and a terminal. Background Art
[0002] In passenger vehicles, the position and posture of the seats can be adjusted to enhance the riding experience. For the driver, a reasonable sitting posture is also related to driving safety. For example, the front and rear adjustment function of the seat can give the legs a reasonable operating space. For another example, the seat back can be adjusted to tilt to ensure a comfortable ride without affecting operation. Some vehicles are also equipped with zero-gravity seats. The seat back, seat cushion and other parts of the zero-gravity seat can be adjusted to make the zero-gravity seat fit the human body curve better. The occupants can lie flat or half-lying on the zero-gravity seat to ensure the user's comfort to the greatest extent.
[0003] However, while the seat adjustment function brings comfort, it also brings more dangers. For example, during the seat adjustment process, the seat is prone to pinching people, threatening the personal safety of the occupants. Summary of the invention
[0004] The present application provides a seat, a seat control method, an intelligent cockpit and a terminal, which can avoid accidents in which people are squeezed and injured due to seat adjustment, and improve the riding comfort and safety of seat occupants.
[0005] In a first aspect, the present application provides a seat, comprising a seat body, a mounting portion and a first pressure sensing module, wherein the mounting portion is fixedly connected to the seat body, the first pressure sensing module is arranged on the mounting portion, the first pressure sensing module comprises a plurality of thin film pressure sensing units, the plurality of thin film pressure sensing units are distributed on a side of the mounting portion facing a seat back of the seat, and the first pressure sensing module is used to collect pressure data.
[0006] In the present application, by setting a first pressure sensing module on the seat back, the pressure data at the seat back can be monitored, so as to better understand whether the passenger behind the seat is squeezed by the seat, thereby improving the comprehensiveness and pertinence of the seat design and improving the riding safety of the occupants.
[0007] Furthermore, by utilizing the thin and light characteristics of the thin film pressure sensing unit and installing it on the mounting part of the seat back, the pressure data can be accurately obtained without affecting the aesthetics of the seat and improving riding safety. For example, when the rear passengers are squeezed, the thin film pressure sensing unit will not cause discomfort to the passengers as hard shell pressure sensors do due to its very thin thickness, and hard shell pressure sensors are prone to aggravate the secondary damage caused by squeezing to the passengers.
[0008] In a possible implementation manner of the first aspect, the mounting portion includes a first plane facing a side of the chair back, and the first pressure sensing module is mounted on the first plane.
[0009] This design allows the first pressure sensing module to be closer to the seat back, allowing it to better sense the squeezing of the rear passengers by the seat and improve safety.
[0010] In another possible implementation of the first aspect, the seat further includes a cover, the cover is used to wrap the seat, and the first pressure sensing module is sandwiched between the mounting portion and the cover.
[0011] This embodiment wraps the seat with a cover, which can increase the aesthetics and cleanliness of the seat. At the same time, the first pressure sensor module is clamped between the mounting portion and the cover, which can better protect the first pressure sensor module and make it less susceptible to damage. Moreover, due to the soft texture of the cover, the normal operation of the first pressure sensor module is not affected.
[0012] In another possible implementation of the first aspect, a groove is provided on the first plane, and the first pressure sensing module is disposed in the groove.
[0013] This can improve the aesthetics and surface smoothness of the seat, as well as the assembly stability and assembly accuracy of the first pressure sensing module. In particular, the seats in the vehicle are often in a bumpy and shaking environment, and the provision of the groove can better fix the first pressure sensing module, making it difficult to move or fall off.
[0014] In yet another possible implementation of the first aspect, a plurality of thin film pressure sensing units are evenly distributed on the mounting portion.
[0015] Evenly distributed multiple thin film pressure sensing units can more comprehensively monitor the pressure data at the seat back, which is beneficial to improving the riding safety of rear passengers and the comprehensiveness of pressure data acquisition, and avoiding unexpected squeezing accidents caused by the lack of thin film pressure sensing units.
[0016] In another possible implementation manner of the first aspect, the plurality of thin film pressure sensing units are strip-shaped, and the plurality of thin film pressure sensing units are arranged in parallel along the first direction on a side of the mounting portion facing the chair back.
[0017] The multiple strip-shaped thin film pressure sensing units in this embodiment can reduce the cost while ensuring the accuracy of obtaining pressure data.
[0018] In another possible implementation manner of the first aspect, the plurality of thin film pressure sensing units are in a strip shape, and the plurality of thin film pressure sensing units are staggeredly arranged on the mounting portion.
[0019] In this embodiment, the multiple thin film pressure sensing units arranged in an interlaced manner can further improve the accuracy of obtaining pressure data, as well as improve the riding comfort and safety of rear passengers.
[0020] In another possible implementation manner of the first aspect, the plurality of thin film pressure sensing units are block-shaped, and the plurality of thin film pressure sensing units are arranged in rows and columns in a matrix form on the mounting portion.
[0021] Considering that the pressure area of the occupant in a special sitting posture is small and not easy to be detected, in this embodiment, a plurality of block-shaped thin film pressure sensing units are arranged in rows and columns in a matrix form on the mounting portion to more comprehensively monitor the pressure data.
[0022] In another possible implementation of the first aspect, the first pressure sensing module includes one or more pressure pads, and the pressure pads include a flexible base material and at least two thin film pressure sensing units integrated in the flexible base material and arranged in rows and columns in a matrix form.
[0023] The above-mentioned implementation can add a flexible base material on the basis of the thin film pressure sensing unit to avoid the situation where the accuracy of the thin film pressure sensing unit decreases due to wear during use, and such a setting can further reduce the safety risk of rear passengers being injured when being squeezed.
[0024] In yet another possible implementation of the first aspect, the first pressure sensing module includes a plurality of pressure pads, and the plurality of pressure pads are staggeredly arranged on a side of the mounting portion facing the seat back.
[0025] In another possible implementation of the first aspect, the seat includes a seat body, a seat controller, and a seat adjustment motor, the seat adjustment motor is used to control the seat body to move, and the seat controller is connected to the first pressure sensing module to control the seat adjustment motor to implement an anti-pinch operation. This implementation improves the process of the anti-pinch operation through the seat controller.
[0026] In another possible implementation of the first aspect, the seat body also includes a seat armrest, a leg rest and a foot rest, and the surfaces of the seat armrest, the leg rest and the foot rest that are in contact with the occupant are respectively provided with a second pressure sensing module, a third pressure sensing module and a fourth pressure sensing module, and the second pressure sensing module, the third pressure sensing module and the fourth pressure sensing module are all used to collect pressure data to realize anti-pinch operation.
[0027] This embodiment improves the robustness of the anti-pinch operation by disposing a second pressure sensing module, a third pressure sensing module and a fourth pressure sensing module at the seat armrest, leg rest, foot rest and other positions, so as to solve the problem of personal injury to passengers caused by seat squeezing in different scenarios.
[0028] In another possible implementation of the first aspect, the seat controller is connected to the second pressure sensing module, the third pressure sensing module and the fourth pressure sensing module respectively to implement anti-pinch operations at corresponding positions.
[0029] In a second aspect, the present application provides a seat control method, which is applied to a vehicle, wherein the vehicle includes a first seat and a second seat, the first seat is arranged in the front row of the second seat, and a first pressure sensing module is arranged on the side of the first seat facing the second seat. The method includes: when the target seat moves, receiving first pressure data collected from the first pressure sensing module, wherein the target seat includes the first seat or the second seat, and the first pressure data includes a first pressure value; obtaining an identification result of an object on the second seat; determining an anti-pinch trigger condition based on the identification result, the anti-pinch trigger condition including that the first pressure value is greater than or equal to a first threshold value; and performing an anti-pinch operation when the first pressure data meets the anti-pinch trigger condition.
[0030] In a possible implementation, the occupants of the rear seats are prevented from being squeezed by limiting the movable distance of the front seats, but this undoubtedly limits the adjustable space of the front seats and sacrifices the riding comfort of the front seat passengers. Through the method of the embodiment of the present application, when the target seat moves, the first pressure sensing module set on the side of the first seat facing the second seat obtains pressure data to sense the occupants of the second seat being squeezed by the first seat, thereby determining whether to perform an anti-pinch operation. Therefore, the embodiment of the present application can avoid the occurrence of safety accidents caused by the front seats squeezing the occupants of the rear seats during movement, and can ensure the adjustable space of the front seats.
[0031] Due to the different physiques and pressure tolerance of passengers, if the anti-pinch triggering conditions are fixed, passengers in the rear seats may still be injured during the squeezing process. However, through the embodiment of the present application, the recognition result of the object on the second seat can be obtained when the target seat moves, and the anti-pinch triggering conditions can be determined based on the recognition results. This means that there are differences in the anti-pinch triggering conditions corresponding to different passengers, so as to ensure that no passenger will be injured during the squeezing process.
[0032] In a possible implementation manner of the second aspect, the anti-pinch operation includes at least one of the following operations: controlling the target seat to stop moving, controlling the target seat to move in the opposite direction, and controlling the backrest of the first seat to adjust forward.
[0033] This embodiment can achieve anti-pinch operation by controlling the target seat to stop moving, move in the opposite direction or adjust the backrest forward, thereby improving the riding safety and riding comfort of the passengers.
[0034] In another possible implementation of the second aspect, controlling the target seat to move in the opposite direction includes: controlling the target seat to move 10% of the movement mileage in the opposite direction, and the movement mileage includes the total mileage of the target seat moving from the starting position to the current position.
[0035] This embodiment prevents the front seats from continuously squeezing the rear passengers by controlling the target seat to move a certain distance (such as 10% of the movement mileage) in the opposite direction.
[0036] In another possible implementation of the second aspect, controlling the target seat to move in the opposite direction includes: controlling the target seat to move in the opposite direction until the first pressure data does not satisfy the anti-pinch trigger condition.
[0037] This embodiment continuously controls the target seat to move in the opposite direction until the first pressure data does not meet the anti-pinch triggering condition, so as to effectively ensure the safety and comfort of the passengers.
[0038] In yet another possible implementation of the second aspect, controlling the backrest of the first seat to adjust forward includes: controlling the backrest of the first seat to adjust forward until the first pressure data does not satisfy the anti-pinch triggering condition.
[0039] In another possible implementation of the second aspect, the vehicle also includes a vision sensor to obtain a recognition result of the object on the second seat, including: receiving the recognition result of the object on the second seat, the recognition result of the object on the second seat is related to data collected by the vision sensor, and the recognition result includes the category of the object on the second seat; when the category of the object on the second seat includes an occupant, identifying the age group of the occupant on the second seat based on second pressure data sent by a pressure sensor on the second seat.
[0040] In the embodiment of the present application, considering the differences in the ability of passengers with different physical conditions to withstand pressure, the combination of visual sensors and pressure sensors can more accurately identify the type of objects on the second seat and the age of the passengers, thereby more comprehensively evaluating the ability of the passengers to withstand pressure and improving the accuracy of the anti-pinch function. Furthermore, by distinguishing the age groups of the passengers, the comprehensiveness of the anti-pinch function is improved.
[0041] In yet another possible implementation of the second aspect, determining an anti-pinch triggering condition according to the recognition result includes:
[0042] The anti-pinch triggering condition is determined based on the recognition result and the age group of the occupant in the second seat.
[0043] In another possible implementation of the second aspect, the first pressure data also includes a pressure area, and the anti-pinch triggering condition includes satisfying one or more of the following conditions: Condition 1, the first pressure value is greater than or equal to a first threshold, Condition 2, the pressure area is greater than or equal to a second threshold.
[0044] By taking the pressure area factor into consideration, this embodiment can more comprehensively monitor the contact between the rear passengers and the front seats, thereby more accurately determining the anti-pinch triggering conditions and improving the riding safety and comfort of the rear passengers.
[0045] In yet another possible implementation of the second aspect, the first pressure data further includes distribution of the pressurized area, and the anti-pinch triggering condition includes a condition related to the distribution of the pressurized area.
[0046] By considering the distribution factors of the pressure area, the comprehensiveness of the anti-pinch function can be improved. For example, if there are objects placed on the rear seats in addition to the passengers, the objects and the passengers may be squeezed by the front seats at the same time, causing the first pressure data to be inconsistent with the estimate. Therefore, by considering the distribution factors of the pressure area, the anti-pinch function can be avoided from being affected by the objects.
[0047] The contact between the occupant and the seat can be monitored in greater detail, allowing for more accurate determination of anti-pinch triggering conditions, improving occupant safety and comfort.
[0048] In another possible implementation of the second aspect, the anti-pinch triggering conditions include one or more of the following conditions: Condition 1, the first pressure value is greater than or equal to the first threshold, Condition 2, the pressure area is greater than or equal to the second threshold, Condition 3, the distribution of the pressure area meets the preset distribution conditions.
[0049] By comprehensively considering factors such as the first pressure value, the pressure area and the distribution of the pressure area, the anti-pinch triggering conditions can be determined more accurately and comprehensively.
[0050] In another possible implementation of the second aspect, before receiving the first pressure data collected from the first pressure sensing module, the method also includes: controlling the first pressure sensing module to collect data under preset collection conditions, wherein the preset collection conditions include one or more of the first seat moving backward, the backrest of the first seat adjusting backward, or the second seat moving forward.
[0051] In this implementation, there is no need to turn on the first pressure sensing module in real time. Instead, the data collection function is turned on under preset collection conditions, thereby reducing energy consumption and saving costs.
[0052] In another possible implementation of the second aspect, the method further includes: outputting first indication information to prompt the user why the anti-pinch operation is performed. By outputting the first indication information to prompt the user why the anti-pinch operation is performed, the user can be better helped to understand the usage of the seat, so that the user can take corresponding measures in time.
[0053] In a third aspect, an embodiment of the present application provides a seat control device, which includes a seat control device, a processing unit and a control unit. The seat control device is used to implement the method described in the second aspect or any possible implementation method of the second aspect.
[0054] In a fourth aspect, an embodiment of the present application provides a seat controller, which includes a processor and a memory; a computer program is stored in the memory; when the processor executes the computer program, the seat controller executes any method described in the second aspect.
[0055] It should be noted that the processor included in the control device described in the fourth aspect above may be a processor specifically used to execute these methods (for convenience of distinction, referred to as a dedicated processor), or a processor that executes these methods by calling a computer program, such as a general-purpose processor. Optionally, at least one processor may include both a dedicated processor and a general-purpose processor.
[0056] Optionally, the computer program may be stored in a memory. Exemplarily, the memory may be a non-transitory memory, such as a read-only memory (ROM), which may be integrated with the processor on the same device or may be separately provided on different devices. The embodiment of the present application does not limit the type of memory and the configuration of the memory and the processor.
[0057] In a possible implementation manner, the at least one memory is located outside the seat controller.
[0058] In yet another possible implementation, the at least one memory is located within the seat controller.
[0059] In another possible implementation, part of the at least one memory is located inside the seat controller, and another part of the memory is located outside the seat controller.
[0060] In the present application, the processor and the memory may also be integrated into one device, that is, the processor and the memory may also be integrated together.
[0061] In a fifth aspect, an embodiment of the present application provides a smart cockpit, which includes a first seat and a second seat, the first seat includes the seat described in the first aspect or any possible embodiment of the first aspect, and the first seat and / or the second seat includes a seat controller as described in the fourth aspect.
[0062] In one possible design, the smart cockpit also includes a visual sensor, and a pressure sensor is integrated into the second seat.

[0087] In passenger vehicles, the position and posture of the seats can be adjusted to enhance the riding experience. For the driver, a reasonable sitting posture is also related to driving safety. For example, the front and rear adjustment function of the seat can give the legs a reasonable operating space. For another example, the seat back can be adjusted to tilt to ensure a comfortable ride without affecting operation. Some vehicles are also equipped with zero-gravity seats. The seat back, seat cushion and other parts of the zero-gravity seat can be adjusted to make the zero-gravity seat fit the human body curve better. The occupants can lie flat or half-lying on the zero-gravity seat to ensure the user's comfort to the greatest extent.
[0088] However, while the seat adjustment function brings comfort, it also brings more dangers. For example, during the seat adjustment process, it is easy for the seat to pinch the occupants, especially when there are many rows of seats, which can easily cause accidents such as squeezing the occupants and causing injuries. Figure 1A The figure is a schematic diagram of a use scenario of a vehicle in the prior art, wherein the vehicle 100 includes a first seat 101 relatively arranged in the front row and a second seat 102 relatively arranged in the back row, and the first seat 101 and / or the second seat 102 have the ability to be adjusted or moved by a motor. Taking the adjustment capability of the first seat 101 as an example, during the movement / adjustment process, the first seat 101 may occupy the back row space of the vehicle 100, squeezing the occupant of the second seat 102, thereby affecting the riding safety and riding comfort of the occupant of the second seat 102.
[0089] In addition, the seats of some vehicles are automatically adjusted. For example, some models support one-key automated seat control solutions such as "one-key queen co-pilot" and "one-key zero gravity", which makes it easier for the seats to squeeze the rear passengers, threatening the personal safety of the passengers. Consider a possible situation. The first seat 101 enters the "one-key zero gravity" mode and needs to fold down the seat back. At this time, the passenger of the second seat 102 is located in the adjustment space of the "one-key zero gravity" mode. Since the "one-key zero gravity" mode automatically controls the movement of the seat, it is very likely that the passenger on the second seat 102 will be piled up. Consider another possible situation. The first seat 101 has been adjusted to a position close to the rear seat. At this time, the passenger of the second seat 102 activates the "zero gravity" mode, and the seat cushion may be adjusted forward, causing the passenger of the second seat 102 to be squeezed.
[0090] In view of this, the embodiments of the present application provide a seat, a seat control method, a smart cockpit and a terminal, which can avoid accidents in which people are squeezed and injured due to seat adjustment, and improve the riding comfort and safety of seat occupants.
[0091] The following takes a vehicle as an example to introduce a terminal provided by an embodiment of the present application. It should be noted that in addition to vehicles, the present application can be applied to other terminals with seats, such as ships, airplanes, or manned equipment, etc., and the vehicle is only used as an example for description here.
[0092] See also Figure 1B , Figure 1B A schematic diagram of a vehicle usage scenario provided in an embodiment of the present application. Figure 1B As shown, the vehicle 100 includes a first seat 101 , a seat controller 1012 , a second seat 102 and a first pressure sensing module 103 .
[0093] The first seat 101 is a seat relatively arranged in the front row, for example, arranged in the front row of the second seat 102. Correspondingly, the second seat 102 is arranged in the rear row of the first seat 101. The first seat 101 is used for the front row passengers of the vehicle 100 to sit, and the second seat 102 is used for the rear row passengers of the vehicle 100 to sit. The first seat 101 is located in front of the second seat 102. Figure 1B In the vehicle with two rows of seats shown, the first seat 101 is a passenger seat of the vehicle 100, and the second seat 102 is a seat behind the passenger seat of the vehicle 100. In some possible implementations, the first seat 101 may also be a main driver's seat (i.e., a driver's seat) of the vehicle 100, and correspondingly, the second seat 102 is a seat behind the main driver's seat of the vehicle 100.
[0094] It should be understood that the two rows and two columns of seats herein are only examples, and the present application is also applicable to other vehicles with more than one row of seats, and / or other vehicles with more or fewer columns of seats. For example, if the vehicle 100 is a vehicle with three rows of seats or even more seats, the first seat 101 can be any seat in the vehicle 100 except the last row of seats, and the second seat 102 is the seat behind the first seat 101.
[0095] In the vehicle 100, the first seat 101 and / or the second seat 102 have the ability to be adjusted or moved by a motor, and the above-mentioned movement or adjustment includes: forward and backward movement of the seat body, forward and backward adjustment of the seat back, forward and backward movement or up and down adjustment of the seat footrest, forward and backward movement or up and down adjustment of the seat leg rest, etc.
[0096] In the embodiment of the present application, a first pressure sensing module 103 is provided on the first seat 101. The first pressure sensing module 103 is provided on the side of the seat back plate of the first seat 101 facing the direction of the second seat, so as to sense whether the seat is squeezing the occupant of the second seat 102 during the movement / adjustment process. As a possible implementation, when it is sensed that the occupant of the second seat 102 is squeezed during the seat adjustment process, the movement of the seat is stopped in time to make room for the occupant of the second seat 102 in the rear row, thereby improving the riding safety and riding comfort of the occupant of the second seat.
[0097] In some solutions, the first seat 101 and the first pressure sensing module 103 may be integrated, for example, the first pressure sensing module 103 is disposed in the first seat 101. In some solutions, the first pressure sensing module 103 may be separately disposed and then fixed to the first seat by a connector or a fixing member.
[0098] The vehicle 100 includes a seat controller 1012, which is a device with computing capabilities. The seat controller 1012 can control the movement of the seat, for example, the movement of the first seat 101 and the second seat 102. The control here may include one or more of controlling the start and stop of the movement, controlling the distance of the movement, controlling the direction of the movement, and controlling the position of the movement. As a possible implementation, the seat controller 1012 can receive the pressure data from the first pressure sensing module 103, and determine whether there is a situation where the occupant of the second seat 102 is squeezed during the seat adjustment process based on the pressure data of the first pressure sensing module 103. When the seat controller 1012 senses that there is a situation where the occupant of the second seat 102 is squeezed during the seat adjustment process, the seat controller 1012 can stop the movement of the seat in time. For a specific introduction, please refer to the introduction of the method embodiment, which will not be described one by one here.
[0099] Optionally, the seat controller 1012 can be integrated into the seat, for example, integrated into the first seat 101 or the second seat 102. In some other possible schemes, the seat controller 1012 can be separately provided from the seat. For example, the seat controller 1012 is one or more of a domain controller (DC), a vehicle integrated / integration unit (VIU), a data center (such as an intelligent driving platform MDC), etc. Exemplarily, the domain controller is, for example, a cockpit domain controller (CDC). In some embodiments of the present application, the seat controller is integrated into the seat as an example for explanation. It should be understood that the present application also applies to the case where the seat controller set is separately provided from the seat.
[0100] In some possible implementations, a pressure sensor 104 is provided on the second seat 102 to sense whether a passenger is sitting on the second seat 102, so as to assist in controlling the seat adjustment function. Furthermore, the pressure sensor 104 can also be used to sense the weight range of the passenger on the second seat 102, thereby facilitating the determination of the age group of the passenger on the second seat 102. The pressure sensor 104 can be provided at a position such as the seat bottom or seat surface of the second seat 102, which is not strictly limited here. The above-mentioned seat surface is the surface of the second seat 102 that contacts the passenger / user during the sitting process.
[0101] In the above embodiment, the data of the pressure sensor 104 can be used to determine whether there is an occupant sitting on the second seat 102, and / or determine the age of the occupant on the second seat 102, so as to assist in determining whether to perform the anti-pinch operation and improve the user experience. Furthermore, the age of the occupant on the second seat 102 can also be used as the trigger threshold of the anti-pinch operation to improve the riding safety and riding comfort of the occupant on the second seat.
[0102] In some possible situations, the data collected by the pressure sensor 104 can be provided to the aforementioned seat controller for seat control.
[0103] In some possible implementations, the vehicle 100 further includes a visual sensor 105, including but not limited to one or more of a UWB radar, a millimeter wave radar, or a vehicle-mounted camera. The visual sensor 105 can collect information about an object sitting on the second seat 102 to facilitate identification of the object on the second seat 102. The objects here include inanimate objects and animate objects, such as human passengers or pets. Optionally, the visual sensor 105 can have object recognition capabilities and can identify objects. Alternatively, the visual sensor 105 can provide the collected information to a device with object recognition capabilities for object recognition.
[0104] In the above embodiment, the object recognition result on the second seat 102 can be used to determine whether there is a passenger sitting on the second seat 102, thereby facilitating the auxiliary determination of whether to perform the anti-pinch operation and improving the user experience.
[0105] Optionally, there are many possible designs for the location of the vision sensor 105. Several possible designs are exemplarily introduced below:
[0106] In one possible design, the visual sensor 105 may be disposed inside the cabin of the vehicle 100. Figure 1B As shown, the vehicle-mounted camera in the visual sensor 105 can be set above the cabin and can capture images in the direction of the second seat.
[0107] In yet another possible design, the vision sensor 105 may be disposed in the headrest of the first seat 101 so as to capture images toward the rear of the first seat 101 .
[0108] In another possible design, the visual sensor 105 can be set on the upper part of the instrument panel (IP) platform, or on the top of the cabin above the IP platform, and capture the image toward the rear of the first seat 101.
[0109] In another possible design, the visual sensor 105 can be arranged outside the cabin, for example, at the position of the left and right rearview mirrors of the vehicle, to collect images of objects entering the cabin for identification. Currently, the aforementioned several locations of the visual sensor 105 are only examples, and there may be other possible designs in the specific implementation process.
[0110] The overall structure of the vehicle is introduced above, and the seat provided in the embodiment of the present application is introduced below.
[0111] Figure 2 A schematic diagram of a seat provided in an embodiment of the present application, wherein the first seat 101 includes a seat body 1014, a mounting portion 1011 and a first pressure sensing module 103. Furthermore, the first seat 101 may also include one or more of a headrest, an armrest, a leg rest, a foot rest, or a neck rest. Among them:
[0112] The seat body 1014 may include a seat plate and a seat back plate. The mounting portion 1011 may be fixedly connected to the seat body 1014, and the first pressure sensing module 103 may be mounted thereon. Exemplarily, the mounting portion may be disposed at a seat back plate, or at an armrest, a leg rest, a foot rest, a headrest, or the like.
[0113] Combine the following Figure 2 , the mounting portion 1011 is exemplarily introduced as a mounting portion arranged at the seat back plate position. In one possible implementation, the mounting portion 1011 is separately arranged from the seat back plate of the first seat 101. Further, the mounting portion 1011 can be fixed to the seat back plate of the first seat 101 by a connecting member, and exemplarily, the connecting member can be a fastener such as a pin or a screw. In another possible implementation, the mounting portion 1011 is the seat back plate of the first seat 101. In other words, the first pressure sensing module 103 can be directly mounted on the seat back plate of the seat 101.
[0114] The first pressure sensing module 103 is disposed on the mounting portion 1011 for collecting pressure data. Optionally, the first pressure sensing module 103 can be connected to the mounting portion 1011 by, for example, fastener connection, gluing, or snap-on fixing, etc., and the connection method is not strictly limited here.
[0115] exist Figure 2 In the seat shown, the present application can collect the pressure conditions on the seat surface by setting a first pressure sensing module 103 on the seat. These pressure conditions can indicate whether the seat is squeezed by an object, thereby sensing the situation in which the front seats in the cabin squeeze the rear passengers, which helps to assist in determining whether to perform anti-pinch operations and improve user experience.
[0116] Understandably, in Figure 2 In the embodiment, the mounting portion 1011 is in the form of a rectangular parallelepiped, and in order to meet the needs of different scenarios, the mounting portion 1011 may be in other shapes such as a cylindrical shape, an irregular shape, etc. In some possible cases, the shape of the mounting portion 1011 should not affect the smoothness of the surface of the first seat 101. In other words, the surface of the mounting portion 1011 is smooth, so that no protrusions are formed on the seat surface. In the subsequent figures, the mounting portion 1011 is shown in the form of a rectangular parallelepiped.
[0117] The following is an exemplary introduction to the installation method of the first pressure sensing module 103 on the installation portion 1011:
[0118] Installation method 1, see Figure 3 The mounting portion 1011 includes a first plane 10111 facing one side of the seat back, and the first pressure sensing module 103 is mounted on the first plane 10111. In this way, the first pressure sensing module 103 arranged on the first plane 10111 can detect pressure data. When the seat is squeezed by an object, the pressure data will present certain characteristics (for example, greater than a certain value, or a change in the pressure value is detected in a certain area), so that it is easy to control the control to achieve anti-pinch.
[0119] Furthermore, the first pressure sensing module 103 covers the entire first plane 10111, improving the surface flatness. In this case, the first pressure sensing module 103 is arranged on the first plane 10111, and the side of the first pressure sensing module 103 used to sense pressure faces the side opposite to the contact surface of the first plane 10111. In order to improve the flatness and aesthetics of the seat surface, in some possible embodiments, the area of the first pressure sensing module 103 is adapted to the area of the backrest of the first seat 101. For example, the area of the pressure-bearing surface of the first pressure sensing module 103 is equal to the area of the surface of the mounting portion 1011 facing the first pressure sensing module 103.
[0120] Installation method 2, the installation portion 1011 includes a first plane 10111 facing the side of the chair back, the first plane 10111 is provided with a groove, and the first pressure sensing module 103 is arranged in the groove. Figure 4 and Figure 5 , Figure 4 A schematic diagram of a mounting portion provided in an embodiment of the present application, Figure 5 A cross-sectional view of a mounting portion provided in an embodiment of the present application. The mounting portion 1011 includes a first plane 10111, and the first plane 10111 is a surface of the mounting portion 1011 facing the chair back. A groove 10112 is provided on the first plane 10111, and the groove 10112 is used to accommodate the first pressure sensing module 103. In some cases, the arrangement and direction of the groove 10112 are consistent with the arrangement and direction of the first pressure sensing module 103.
[0121] In one possible scenario, since the first plane 10111 is the surface on the first seat 101 that easily contacts the occupant on the second seat 102, in order to ensure the aesthetics and smoothness of the seat, the first plane 10111 may be composed of one plane or multiple planes, or may be a curved surface.
[0122] In order to fully detect the area covered by the backrest of the first seat 101 , in some possible solutions, the first pressure sensing module 103 includes a plurality of thin film pressure sensing units, which are distributed on the side of the mounting portion 1011 facing the backrest of the first seat 101 .
[0123] The thin film pressure sensing unit is a device for measuring pressure, which is usually composed of adhesive, carbon paste, gasket, tail and silver conductor. In addition, the thin film pressure sensing unit can be divided into a one-dimensional pressure sensing unit, a two-dimensional pressure sensing unit, a three-dimensional single-point pressure sensing unit and a three-dimensional multi-point pressure sensing unit. A one-dimensional single-point pressure sensing unit can only sense force in one direction, a two-dimensional single-point pressure sensing unit can sense force in two directions, a three-dimensional single-point pressure sensing unit can sense force in three directions, and a three-dimensional multi-point pressure sensing unit can sense force in multiple directions at the same time. In an embodiment of the present application, the thin film pressure sensing unit is any of the above-mentioned thin film pressure sensing units that can sense the force in the direction of the rear seats after being set.
[0124] See also Figure 6 , Figure 6 A front view of a thin film pressure sensing unit provided in an embodiment of the present application, Figure 6 The thin film pressure sensing unit 1031 is strip-shaped, which indicates that the outer contour of the pressure-bearing surface of the thin film pressure sensing unit 1031 is rectangular. The pressure-bearing surface of the thin film pressure sensing unit faces the back side of the seat, and is used to collect the pressure data on the back side of the seat.
[0125] The thickness of the thin film pressure sensing unit 1031 can be adjusted according to actual application requirements, but is usually in the range of several hundred nanometers to several tens of micrometers. In order to ensure the sensitivity of the sensor without affecting the aesthetics of the seat, in some possible implementations, the thickness of the thin film pressure sensing unit 1031 is between 0.05 millimeters (mm) and 0.5 mm.
[0126] In order to enable the first pressure sensing module 103 to accurately sense the pressure data caused by the occupant on the second seat 102, in some possible implementations, the length of the thin film pressure sensing unit 1031 in the second direction is 160 mm, and the width of the thin film pressure sensing unit 1031 in the first direction is 13.1 mm. Optionally, the length of the thin film pressure sensing unit 1031 in the second direction may also be 250 mm, and the width of the thin film pressure sensing unit 1031 in the first direction may also be 15 mm.
[0127] In some cases, the thin film pressure sensing unit includes a wire harness 10311, and the wire harness 10311 is used to connect with other devices, including a seat controller and / or a seat adjustment motor. Optionally, the wire harness 10311 or a part of the wire harness 10311 is arranged on the mounting portion 1011, and accordingly, the wire harness 10311 can be built into the mounting portion 1011. In this case, the mounting portion 1011 is provided with a accommodating cavity corresponding to the wire harness 10311. In addition, the wire harness 10311 can also be arranged in the groove 10112 of the mounting portion 1011. In this case, the shape of the groove 10112 needs to be adaptively modified. For example, an area for accommodating the wire harness 10311 is provided in the groove 10112, or the groove 10112 is provided with an extension portion to arrange the wire harness 10311.
[0128] In a possible implementation, a plurality of thin film pressure sensing units are evenly distributed on the mounting portion 1011. Exemplarily, the plurality of thin film pressure sensing units are disposed at the middle and upper portion of the backrest of the first seat 101. In another exemplary embodiment, the plurality of thin film pressure sensing units are disposed at the position where the legs of the occupant of the second seat 102 may touch in a normal sitting position.
[0129] As an implementation example of uniform distribution, multiple thin film pressure sensing units can be laid out at a specific interval, such as between 5 cm and 10 cm, and this interval can be adjusted according to actual needs.
[0130] Furthermore, a plurality of thin film pressure sensing units are evenly distributed on the first plane of the mounting portion. Figure 7 , Figure 7A front view of a thin film pressure sensing unit provided in an embodiment of the present application installed on a mounting portion, wherein the mounting portion 1011 includes a first plane 10111, and the thin film pressure sensing unit 1031 is installed on the first plane 10111. Figure 7 The normal viewing direction is the direction perpendicular to the first plane, Figure 7 The first plane 10111 in the figure is evenly arranged with a plurality of thin film pressure sensing units 1031. The plurality of thin film pressure sensing units 1031 are arranged in parallel and at equal intervals along the first direction on the side of the mounting portion 1011 facing the chair back. The plurality of thin film pressure sensing units 1031 are distributed at equal intervals. In actual applications, due to the existence of design and installation errors, the error of the intervals of the plurality of thin film pressure sensing units 1031 is about 10%.
[0131] Optionally, the first plane 10111 on the mounting portion 1011 is not provided with the groove 10112 . In this case, the plurality of thin film pressure sensing units 1031 are arranged on the first plane 10111 .
[0132] Optionally, a first plane 10111 on the mounting portion 1011 is provided with grooves 10112 , and the plurality of thin film pressure sensing units 1031 are respectively disposed in the grooves 10112 on the first plane 10111 of the mounting portion 1011 .
[0133] Further, in Figure 7 In the embodiment, a plurality of thin film pressure sensing units 1031 are distributed at equal intervals along a first direction, and the intervals between the thin film pressure sensing units 1031 are preferably 20 mm; the intervals account for 3.85% of the total width of the chair back / mounting portion.
[0134] In order to save costs and maximize the sensor sensing efficiency, the area of the pressure-bearing surface of a single thin film pressure sensing unit 1031 accounts for 10.15% of the first plane 10111 .
[0135] Further, in Figure 7 In the embodiment, the first pressure sensing module includes five thin film pressure sensing units 1031. In this case, the first seat 101 senses the squeezed state of the occupant of the second seat 102 through the five thin film pressure sensing units 1031. Of course, the present application adopts five thin film pressure sensing units 1031 to ensure a balance between cost and sensor sensing efficiency. In different implementation scenarios, the number of thin film pressure sensing units 1031 may be more or less, but it is understandable that the more the number of thin film pressure sensing units 1031, the higher the sensor sensing efficiency, the larger the perceptible area, and the more accurate the sensing of the position where the backlog is generated, the higher the corresponding cost, and vice versa.
[0136] In a possible implementation, the mounting portion 1011 further includes a second plane facing the bottom of the seat, and the first pressure sensing module 103 further includes one or more thin film pressure sensing units 1031 laid on the second plane, and the one or more thin film pressure sensing units 1031 laid on the second plane are used to sense whether the seat squeezes the feet of the rear passengers during the movement. Optionally, the mounting portion 1011 can be set at the back of the seat, or the mounting portion can be set at the bottom of the seat plate of the seat.
[0137] See also Figure 8 , Figure 8 A front view of another thin film pressure sensing unit provided in an embodiment of the present application installed on a mounting portion, Figure 8 The thin film pressure sensing unit 1031 is in a strip shape. In this case, the first pressure sensing module 103 may include a plurality of thin film pressure sensing units 1031 equidistantly distributed along the first direction, and a plurality of thin film pressure sensing units 1031 equidistantly distributed along the second direction. Figure 8 In the embodiment, the thin film pressure sensing units 1031 are staggeredly arranged on the first plane 10111 on the mounting portion 1011 to obtain a larger sensing area.
[0138] In one possible implementation, see Fig. 9 , Fig. 9 A front view of another thin film pressure sensing unit provided in an embodiment of the present application installed on a mounting portion. Fig. 9 The plurality of thin film pressure sensing units 1031 are block-shaped, and the outer contour of the pressure-bearing surface of the plurality of thin film pressure sensing units 1031 is square. The area of the pressure-bearing surface of the thin film pressure sensing unit 1031 in this embodiment is smaller than that of the strip-shaped thin film pressure sensing unit 1031.
[0139] Fig. 9 The multiple thin film pressure sensing units 1031 are arranged in a matrix form on the first plane 10111 of the mounting portion 1011. The multiple thin film pressure sensing units 1031 are arranged in multiple columns vertically and multiple rows horizontally. The thin film pressure sensing units 1031 in each column are distributed at equal intervals, and the thin film pressure sensing units 1031 in each row are distributed at equal intervals. Optionally, the spacing between two adjacent thin film pressure sensing units 1031 in the same row or the same column is equal, and the spacing between each thin film pressure sensing unit 1031 and the adjacent thin film pressure sensing unit 1031 in the first direction is 8 mm, and the spacing between each thin film pressure sensing unit 1031 and the adjacent thin film pressure sensing unit 1031 in the second direction is 8 mm.
[0140] In some possible embodiments, in order to more accurately detect the usage status of the seat, especially the sitting posture and position of the occupant, the area of the pressure surface of the block-shaped film pressure sensing unit can be relatively small, for example 25 square millimeters. This can save costs while sensing the pressure area of the occupant on the second seat 102 and its own pressure area.
[0141] In a possible implementation, the width and length of the block-shaped thin film pressure sensing unit 1031 are equal, both of which are 10 mm. Of course, in different implementations, the width and length of the block-shaped thin film pressure sensing unit 1031 may not be equal, and may also be other values.
[0142] Apart from Fig. 9 In addition to the block-shaped thin film pressure sensing unit 1031 shown, the thin film pressure sensing unit 1031 may also be in other shapes, such as diamond, circle, etc. The specific implementation method shall be subject to the actual situation. It is worth noting that no matter what shape the thin film pressure sensing unit 1031 is, the spacing between them is Fig.10 In the same or similar case, the thin film pressure sensing units 1031 are still evenly distributed on the mounting portion 1011 in a matrix shape.
[0143] In some possible implementations, in order to improve the use efficiency of the thin film pressure sensing unit 1031, the thin film pressure sensing unit 1031 can be arranged in the middle and upper part of the backrest of the first seat 101, and in the position where the legs of the occupant of the second seat 102 may touch in a normal sitting position, see Fig.10 , Fig.10 A front view of another thin film pressure sensing unit provided in an embodiment of the present application installed on a mounting portion.
[0144] Fig.10 The thin film pressure sensor unit is arranged in the position where the legs of the rear passengers may touch the position when they are in a normal sitting position.
[0145] It should be noted that the block-shaped thin film pressure sensing unit 1031 in this embodiment can be arranged on the first plane 10111 or in the groove 10112 of the mounting portion 1011 .
[0146] In a possible implementation, the first pressure sensing module 103 includes a thin film pressure sensing unit 1031 . The thin film pressure sensing unit 1031 is block-shaped and covers the first plane 10111 of the mounting portion 1011 .
[0147] In a possible implementation, in order to reduce the pressure feeling of the occupant on the second seat 102 when being squeezed by the first seat and improve comfort, this implementation proposes a pressure pad, see Fig.11 , Fig.11 A schematic diagram of a pressure pad provided in an embodiment of the present application, in Fig.11 In the embodiment, the pressure pad 1032 includes a flexible base material 1033 and a plurality of thin film pressure sensing units 1031 integrated in the flexible base material 1033 and arranged in rows and columns in a matrix form. The plurality of thin film pressure sensing units 1031 are connected to each other by wire harnesses 10311 respectively. In the present embodiment, the thin film pressure sensing units 1031 arranged along the first direction are connected to each other, and the wire harnesses 10311 of the plurality of thin film pressure sensing units 1031 in the same row are integrated into one bundle.
[0148] In a possible implementation, the first pressure sensing module 103 may include one or more pressure pads 1032 . The one or more pressure pads 1032 may be disposed on the first plane 10111 of the mounting portion 1011 , or may be disposed in the groove 10112 of the mounting portion 1011 .
[0149] In a possible implementation, the first pressure sensing module 103 includes a plurality of pressure pads 1032, see Fig.12 , Fig.12 This is a front view of a pressure pad provided in an embodiment of the present application installed on a mounting portion, wherein a plurality of pressure pads 1032 are staggeredly arranged on a side of the mounting portion 1011 facing the seat back to more comprehensively detect the sitting posture of the occupant on the second seat 102 .
[0150] In a possible embodiment, the headrest, leg rest, foot rest and armrest of the first seat 101 are also provided with a mounting portion 1011. The first pressure sensing module 103 can be set on the mounting portion 1011 located at the headrest. The first pressure sensing module 103 is distributed on the side of the mounting portion 1011 facing the seat back. The first pressure sensing module 103 in this embodiment is used to collect pressure data to determine whether the backrest or headrest of the first seat 101 squeezes the riding space of the rear passengers during the adjustment process, so as to realize anti-pinch operation.
[0151] Further, the first pressure sensing module 103 is disposed on a side of the mounting portion 1011 that may be pressed against a seat occupant, and correspondingly, the side that may be pressed against a seat occupant is a first plane 10111 .
[0152] In some possible implementations, the IP platform glove box, the door switch, the side of the door facing the inside of the vehicle 100 and other locations that may squeeze the user are all provided with pressure sensing modules, further enriching the possible realization of the anti-pinch function. The pressure sensing module may also include multiple thin film sensing units, and the arrangement of the thin film sensing units is as shown in FIG. Figures 7 to 11 One or more arrangements in .
[0153] In a possible implementation, the first seat 101 further includes a seat control motor. Fig.13 The first seat 101 may also include a seat adjustment motor 1013 for controlling the forward and backward movement of the seat body 1014. The seat controller 1012 is connected to the seat adjustment motor 1013. When the pressure data changes and causes squeezing of the rear passengers, the seat controller 1012 controls the seat adjustment motor 1013 to implement an anti-pinch operation.
[0154] In a possible implementation, the first seat 101 further includes a seat controller. Fig.13 The seat controller 1012 is used to obtain the pressure data output by the film pressure sensing unit 1031, and perform anti-pinch operation according to the data. The seat controller 1012 can be an independent electronic device or an integrated module, and its size and shape can be designed according to actual needs. In the embodiment, we select a microcontroller with wireless communication function as the seat controller.
[0155] In a possible implementation, since the thin film pressure sensing unit 1031 is relatively soft and has limited strength, in order to ensure that the thin film pressure sensing unit 1031 can work properly and avoid the durability of the thin film pressure sensing unit 1031 being affected and being damaged by misuse by users, it is not directly arranged on the seat surface. The first seat 101 also includes a cover, which is used to wrap the seat. For details, please refer to Fig.14 and Fig.15 , Fig.14 This is a schematic diagram of a face cover wrapping installation portion provided in an embodiment of the present application. Fig.15 This is a cross-sectional view of a mask wrapping the mounting portion provided in an embodiment of the present application, wherein the first pressure sensing module 103 is sandwiched between the mounting portion 1011 and the mask 1015. Fig.14 In the embodiment, the first pressure sensing module 103 is disposed in the groove 10112 on the mounting portion 1011 , and the outer surface of the first pressure sensing module 103 facing the face cover 1015 is in contact with the face cover 1015 .
[0156] In a possible embodiment, the seat also includes a seat armrest, a leg rest, and a foot rest. The surfaces of the seat armrest, leg rest, and foot rest that are in contact with the occupant are respectively provided with a second pressure sensing module, a third pressure sensing module, and a fourth pressure sensing module. The third pressure sensor, the fourth pressure sensor, and the fifth pressure sensor are all used to collect pressure data to implement anti-pinch operations at corresponding positions. For example, when the seat armrest is rotating, the third pressure sensor arranged on the surface of the seat armrest that is in contact with the occupant senses that the occupant's hand is squeezed and transmits the data to the seat controller 1012 in real time. The seat controller 1012 implements the anti-pinch operation by adjusting the adjustment motor corresponding to the seat armrest.
[0157] Optionally, the seat controller 1012 is connected to the second pressure sensing module, the third pressure sensing module and the fourth pressure sensing module to implement anti-pinch operations at corresponding positions.
[0158] In this embodiment, in addition to the seat adjustment motor 1013 for controlling the movement of the seat body 1014, the first seat 101 also includes an adjustment motor for controlling the adjustment / movement of the seat armrests, leg rests, and foot rests, and the adjustment motor is connected to the seat controller 1012.
[0159] See also Fig.16 , Fig.16 A flow chart of a seat control method provided in an embodiment of the present application is shown in FIG. Optionally, the method is applied to a vehicle, which may be Figure 1B The vehicle comprises a first seat and a second seat, the first seat is arranged in front of the second seat, and a first pressure sensing module is arranged on a side of the first seat facing the second seat, wherein the first seat can be Figure 3 or Fig.13 The execution subject of this method is the seat controller. Fig.16 The control method shown includes steps S1601 to S1604. It should be understood that the above step sequence is for the convenience of description and is not intended to limit the execution to the above sequence in specific implementation. This application does not limit the execution sequence, execution time, execution number, etc. of the above steps. Among them, steps S1601 to S1604 are as follows:
[0160] Step S1601: When the target seat moves, the seat controller receives first pressure data collected from the first pressure sensing module.
[0161] The seat controller is a device with computing and control capabilities. For example, the seat controller can be Figure 1B The seat controller 1012 shown, or the seat controller can be Fig.13 Seat controller 1012 is shown.
[0162] Optionally, the seat controller may be arranged in the first seat, wherein the first seat is a seat arranged relatively in the front row. A second seat is also arranged behind the first seat, and the first seat and the second seat may be included in the passenger-carrying terminal. Figure 1B The first seat may be a front seat in the vehicle 100 (ie, the first seat 101 ), and the second seat may be a rear seat in the vehicle 100 (ie, the second seat 102 ).
[0163] The target seat includes the first seat or the second seat. The target seat can perform a variety of movements, and four possible situations are listed below as examples, as follows:
[0164] In case one, the target seat is the first seat, and the target seat movement is that the body of the first seat moves backward.
[0165] In case 2, the target seat is the first seat, and the target seat movement is the rearward adjustment of the backrest of the first seat.
[0166] In case three, the target seat is the second seat, and the target seat movement is that the body of the second seat moves toward the first seat.
[0167] In case four, the target seat is the second seat, and the target seat movement is that the footrest of the second seat is adjusted forward.
[0168] The first pressure sensing module is arranged on the side of the first seat facing the second seat, and is used to collect the first pressure data between the occupant or object on the second seat and the pressure surface of the first pressure sensing module. The first pressure data may include one or more of the pressure value, pressure area, pressure region or distribution of pressure region (or position of pressure region), etc. The following are introduced respectively:
[0169] 1) Pressure value (or first pressure value), which is used to indicate the magnitude of pressure. In some embodiments, the first pressure value represents the value of pressure collected by the first pressure sensing module when the target seat moves.
[0170] 2) Pressure area: In some solutions, the pressure area is used to determine whether the first seat is squeezing the occupant of the second seat, rather than other objects, to improve the accuracy of the anti-pinch operation.
[0171] 3) Pressure area. The pressure area represents the specific location of the area where the first pressure value collected by the first pressure sensing module is not 0. The pressure area also includes the distribution of the pressure area. The distribution of the pressure area represents the distribution of the area where the first pressure value collected by the first pressure sensing module is not 0 on the pressure surface of the first pressure sensing module. The role of the pressure area or the distribution of the pressure area is similar to that of the pressure area, and is also used to determine whether the first seat causes compression to the occupant of the second seat.
[0172] In some possible implementations, the pressurized area or the distribution of the pressurized area can be determined by the corresponding position of the first pressure value provided by the first pressure sensing module, or by the preset installation position or number of the thin film pressure sensing units belonging to different positions in the first pressure sensing module that provides the first pressure value.
[0173] 4) Pressure change rate. The pressure change rate is generally related to the speed of seat movement. Therefore, the pressure change rate in this embodiment includes one or more fixed values. In addition, the pressure change rate is also related to the sitting posture or items of the occupant on the second seat. For example, when the occupant on the second seat feels squeezed by the front seat, he or she may take defensive actions, such as using his or her legs to support the back of the front seat, which means that the occupant feels uncomfortable due to being squeezed. In this case, the pressure change rate is also affected by the force of the occupant on the second seat on the front seat. Specifically, the pressure change rate will undergo nonlinear changes after human intervention.
[0174] In some possible implementations, when the pressure change rate changes nonlinearly, it can be determined that the occupant of the second seat is squeezed and feels uncomfortable.
[0175] In some possible implementations, the above data may be used alone or in combination, for example, combining the first pressure value, the pressure area, the pressure region or the distribution of the pressure region as a criterion for determining whether the occupant of the second seat is squeezed.
[0176] The first pressure sensing module is not always in working state. In one possible implementation, the first pressure sensing module operates under preset collection conditions, and the preset collection conditions include one or more of the first seat moving backward, the backrest of the first seat adjusting backward, or the second seat moving forward. In other words, for the first pressure sensing module arranged on the front seat, when the first pressure sensing module itself or the rear seat is in motion, it can enter the working state to collect data. Furthermore, when the preset collection conditions are not met, the first pressure sensing module can be in a dormant state or a power-off state, thereby reducing the power consumption of the entire vehicle and extending its service life.
[0177] In a possible implementation, the pressure sensing module can be controlled by the seat controller to enter a working state or a dormant state. For example, under a preset collection condition, the seat controller controls the first pressure sensing module to collect data and responds to receiving the first pressure data collected by the first pressure sensing module.
[0178] In some possible implementations, the seat controller may include a receiver, a communication port or a communication unit, and the above step S1601 may be implemented by the receiver, the communication port or the communication unit in the seat controller.
[0179] Step S1602: The seat controller obtains the recognition result of the object on the second seat.
[0180] The recognition result is used to indicate the object (including living objects) placed or sitting on the second seat. The object can be an article, a pet, or an occupant. The article is an inanimate object, such as a safety seat. The pet can be, for example, a cat, a dog, etc. Of course, the recognition result may be any combination of the above-mentioned articles, pets, and occupants. For example, a child is sitting in a safety seat placed on the second seat. In this case, the recognition result includes the article and the occupant.
[0181] Several possible implementation methods for obtaining the recognition result are listed below.
[0182] Implementation method 1: The recognition result is determined by a visual sensor in the vehicle, and the visual sensor includes one or more of a UWB radar, a millimeter wave radar, and a vehicle-mounted camera. Further, the recognition result can be determined based on the information related to the occupant collected by the visual sensor, and the information related to the occupant includes: one or more of the video of the occupant, the image of the occupant, the point cloud data of the occupant, and the infrared data of the occupant.
[0183] In the aforementioned embodiment, the recognition result may be sent directly by the visual sensor, or the visual sensor may send information associated with the items on the second seat to the seat controller, and the seat controller may determine the recognition result based on the information associated with the items on the second seat.
[0184] Implementation 2: The recognition result may be determined by the data processing device based on the information collected by the visual sensor. As a possible implementation, the data processing device determines the object on the second seat based on the video or image collected by the image sensor. The above determination process includes determining the category of the object on the second seat, and the category includes one or more of items, pets, or passengers. The data processing device here is used to exemplarily describe a device with data processing capabilities. In a specific implementation, it may be a seat controller, a domain controller, or an intelligent driving controller, etc., which is not limited here.
[0185] Implementation method 3: The recognition result is determined by the second pressure data collected by the pressure sensor provided on the second seat, or is determined comprehensively by the second pressure data and the data collected by the vision system sensor.
[0186] Exemplarily, the visual system sensor in the vehicle is turned on in real time, and when the second seat is identified as occupied, the visual system sensor sends the recognition result of the object on the second seat to the seat controller. In some schemes, this scheme can be implemented when the seat is identified as occupied. If the first seat is not identified as occupied, the method stops executing.
[0187] The above implementations are only examples, and the specific implementation process may include more ways to obtain the recognition result of the object on the second seat. The above implementations may also be combined without being mutually exclusive.
[0188] In a possible implementation, when the recognition result includes the occupant, the recognition result also includes the age group of the occupant. The age group of the occupant may be determined based on the second pressure sensor on the second seat, or may be determined based on the vision sensor, or may be determined based on the second pressure sensor and the vision sensor in combination.
[0189] In the case where the age group of the occupant is determined based on the second pressure sensor on the second seat, the seat controller / seat control device determines the age group of the occupant based on the second pressure value in the second pressure data collected by the second pressure sensor. It can be understood that different age groups correspond to different second pressure values. Of course, in addition to the second pressure value, other data collected by the second pressure sensor can also be used to determine the age group of the occupant, such as the pressure area or pressure surface.
[0190] In the case where the age group of the occupant is determined based on the visual sensor, the seat controller / seat control device determines the age group of the occupant on the second seat based on the information related to the object placed or seated on the second seat collected by the visual sensor. In order to further improve the accuracy of the anti-pinch triggering condition and avoid errors in the judgment of the age group of the occupant due to the influence of the objects and / or pets placed on the second seat, the seat controller / seat control device determines the age group of the occupant on the second seat based on the facial information and / or body information of the occupant on the second seat collected by the visual sensor. The facial information and / or body information is used to determine the feature points or feature values between the pre-stored facial information and / or body information belonging to different age groups, and then the age group of the occupant on the second seat is determined based on the feature points or feature values.
[0191] As a possible implementation, when the age group of the occupant is determined comprehensively based on the second pressure sensor and the visual sensor, the seat controller / seat control device first determines the preliminary result of the age group of the occupant on the second seat based on the second pressure value collected by the second pressure sensor, and then determines whether the preliminary result is accurate based on the information related to the occupant collected by the visual sensor, and then obtains the final result.
[0192] It can be understood that the above method of determining the age group of the occupants is exemplary, and in practical applications, other methods besides this can also be used to determine the age group of the occupants.
[0193] In one possible implementation, the age group of the occupant is determined by controlling the visual sensor and / or the second pressure sensor to collect information related to the occupant after the seat controller receives the recognition result including the occupant. It may also be received from other devices with recognition capabilities, such as a vehicle integrated unit.
[0194] In a possible implementation manner, the recognition result further includes the gender of the occupant, specifically, the gender of the occupant is determined based on a visual sensor.
[0195] Step S1603: The seat controller determines the anti-pinch triggering condition according to the recognition result.
[0196] The anti-pinch triggering condition includes that the first pressure value is greater than or equal to the first threshold value, which means that the anti-pinch operation is performed when the first pressure value collected by the first pressure sensing module is greater than the first threshold value.
[0197] In a possible implementation manner, when the first pressure data collected by the first pressure sensing module also includes the pressure area, the anti-pinch triggering condition includes satisfying one or more of the following conditions:
[0198] Condition 1: the first pressure value is greater than or equal to the first threshold;
[0199] Condition 2: the pressure area is greater than or equal to the second threshold.
[0200] Optionally, the above conditions can be connected by "or" or "and". Taking the "or" connection as an example, when at least one of condition 1 and condition 2 is met, it is considered that the anti-pinch trigger condition is met. Taking the "and" connection as an example, when both condition 1 and condition 2 are met, it is considered that the anti-pinch trigger condition is met.
[0201] In a possible implementation manner, when the first pressure data collected by the first pressure sensing module also includes the distribution of the pressure-bearing area, the anti-pinch triggering condition includes one or more of the following conditions:
[0202] Condition 1: the first pressure value is greater than or equal to the first threshold;
[0203] Condition 2: the pressure area is greater than or equal to the second threshold;
[0204] Condition 3: The distribution of the compressed area meets the preset distribution conditions.
[0205] In practical applications, the above three conditions can be used as anti-pinch triggering conditions individually, simultaneously, or in combination. The following lists seven possible situations as examples.
[0206] In case 1, condition 1 is used alone as the anti-pinch trigger condition.
[0207] In case 2, condition 2 is used alone as the anti-pinch trigger condition.
[0208] Case three: condition 3 is used alone as the anti-pinch trigger condition.
[0209] Case 4: Condition 1 and Condition 2 are used as anti-pinch triggering conditions. In this case, Condition 1 and Condition 2 can be used as judgment criteria for triggering the anti-pinch operation at the same time. For example, when the first pressure value is greater than or equal to the first threshold value, and the pressure area is greater than or equal to the second threshold value, it is determined to perform the anti-pinch operation.
[0210] Furthermore, conditions 1 and 2 are triggered successively to serve as the judgment criteria for triggering the anti-pinch operation. For example, when the first pressure value is greater than or equal to the first threshold, it is judged whether the pressure area is greater than or equal to the second threshold. If the pressure area is greater than or equal to the second threshold, it is not necessary for the first pressure value to be greater than or equal to the first threshold, and the anti-pinch operation is also determined to be executed. In this way, the problem of the change of sitting posture of the occupant of the second seat when being squeezed by the first seat is solved. The following is an exemplary explanation of the problem of changing sitting posture. For example, the knee of the occupant of the second seat is squeezed by the first seat. At this time, the first pressure value collected by the first pressure sensing module is greater than or equal to the first threshold, but the pressure area is less than the second threshold, and the anti-pinch triggering condition is not met; accordingly, the occupant of the second seat avoids the movement of the first seat, resulting in the pressure area collected by the first pressure sensing module being greater than or equal to the second threshold, but the first pressure value is less than the first threshold. In this case, it is still determined to execute the anti-pinch operation.
[0211] In case 5, condition 1 and condition 3 are used as the anti-pinch triggering conditions. Similar to case 4, condition 1 and condition 3 can be used as the judgment criteria for triggering the anti-pinch operation at the same time, or they can be triggered one after another as the judgment criteria for triggering the anti-pinch operation.
[0212] Case 6: Condition 2 and Condition 3 are used as the anti-pinch triggering conditions. Similar to Case 4, Condition 2 and Condition 3 can be used as the judgment criteria for triggering the anti-pinch operation at the same time, or they can be triggered one after another as the judgment criteria for triggering the anti-pinch operation.
[0213] Case 7: Condition 1, Condition 2 and Condition 3 are used as anti-pinch triggering conditions. Similar to Case 4, Condition 1, Condition 2 and Condition 3 can be used as the judgment criteria for triggering the anti-pinch operation at the same time, or they can be triggered one after another as the judgment criteria for triggering the anti-pinch operation.
[0214] In a possible implementation, the anti-pinch triggering condition includes that the pressure change rate does not conform to the preset linear change law, which means that the anti-pinch operation is performed when the pressure change rate does not conform to the preset linear change law. Specifically, when the first seat squeezes the inanimate object on the second seat, the pressure change rate is generally linear or has a value of 0, while when the first seat squeezes the living object on the second seat, the living object will have more violent defensive movements or struggling movements when it feels uncomfortable under the squeezing. In this case, the pressure change rate does not conform to the preset linear change law. This implementation can improve the comprehensiveness of the anti-pinch function.
[0215] In a possible implementation manner, when the first pressure data collected by the first pressure sensing module also includes the pressure change rate, the anti-pinch triggering condition includes satisfying one or more of the following conditions:
[0216] Condition 1: the first pressure value is greater than or equal to the first threshold;
[0217] Condition 2: the pressure area is greater than or equal to the second threshold;
[0218] Condition 3: the distribution of the pressure area meets the preset distribution conditions;
[0219] Condition 4: The pressure change rate does not conform to the preset linear change law.
[0220] In a possible implementation, the seat controller / seat control device determines the anti-pinch triggering condition according to the recognition result and the age group of the occupant on the second seat. This means that the first threshold, the second threshold, and the preset distribution condition applied in the above implementation can be determined according to the age group of the occupant. The first threshold is used as an example below, and the second threshold and the preset distribution condition are similar to the value logic of the first threshold.
[0221] For example, the age range of the occupants can be divided into {0-10}, {10-20}, {20-30}, ..., {60 and above}, where the unit of the above numbers is years. The first threshold corresponding to {0-10} is 50 Newtons (N), and the first threshold corresponding to {20-30} is 180N.
[0222] In a possible implementation, since the categories of occupants can be roughly divided into children, adults and the elderly, for example, {0-10}, {10-20} are children, {60 and above} are the elderly, and the rest are adults, considering that the ability of occupants in the same category to withstand stress is relatively similar, and the ability to withstand stress changes adaptively with age, the difference between the first thresholds corresponding to different age groups in the same category of occupants changes linearly, for example, the first thresholds corresponding to adults of {20-30}, {30-40}, {40-50}, and {50-60} are 180N, 190N, 200N, and 210N, respectively, and the difference between the first thresholds corresponding to different age groups in the same category of occupants is 10N, which falls within the category of linear change.
[0223] Furthermore, considering that different categories of occupants have different abilities to withstand stress, for example, the ability of children and the elderly to withstand stress is much different from that of adults, the difference between the first thresholds corresponding to different categories of occupants is nonlinear, and the first threshold corresponding to children and the elderly is lower than the first threshold corresponding to adults.
[0224] In a possible implementation, since the gender of the occupants can be divided into male and female, there are differences in the first thresholds corresponding to male occupants and female occupants, and the first threshold for male occupants is higher than the first threshold for female occupants.
[0225] In one possible implementation, since the occupant's ability to withstand pressure varies in different sitting postures, in order to improve the recognition robustness of the anti-pinch operation, the first threshold value is taken as multiple values. The specific value is determined according to the first pressure value collected by the first pressure sensing module when the same occupant is squeezed by the first seat at the same movement mileage in different sitting postures. For example, occupant A feels uncomfortable when being squeezed by the first seat at a certain movement mileage in the first sitting posture, and the first pressure value collected by the first pressure sensing module is the first value. When occupant A is squeezed by the first seat at the same movement mileage in the first sitting posture, the first pressure value collected by the first pressure sensing module is the second value. And so on, multiple values are obtained. In this case, the value of the first threshold includes multiple values such as the first value and the second value.
[0226] Furthermore, in order to improve the riding comfort of rear passengers, the value of the first threshold is the lowest value among the above multiple values.
[0227] Furthermore, different sitting postures correspond to different first thresholds. When the occupant on the second seat contacts the backrest of the second seat, the current sitting posture of the occupant on the second seat is determined based on the relevant information collected by the visual sensor, and then the first threshold is determined based on the current sitting posture. It can be understood that the second threshold and the preset distribution condition can also be determined based on the sitting posture of the occupant on the second seat.
[0228] In a possible embodiment, when the categories of objects include occupants and items, the value of the first threshold is related to the items on the second seat, such as a child seat. When the child seat is placed on the seat, there is a protruding portion partially facing the front seat. However, due to changes in the sitting posture of the occupants, the protruding portion may or may not affect the first pressure data collected by the first pressure sensing module. However, considering the randomness of the occupants when riding, the corresponding first threshold is determined based on the protruding portion and the occupant distribution, which represents that the first pressure value collected by the first pressure sensing module is greater than or equal to the first threshold corresponding to the protruding portion, and / or the first pressure value collected by the first pressure sensing module is greater than or equal to the first threshold corresponding to the occupant, and it is determined to perform an anti-pinch operation.
[0229] The above numerical values are exemplary only. The numerical values used in the specific implementation process are determined according to actual conditions and are not limited here.
[0230] It should be noted that the above-mentioned embodiments can be combined arbitrarily. Accordingly, when combined, the first threshold, the second threshold and the preset distribution condition need to simultaneously meet the requirements of the combined embodiments. For example, if the recognition result on the second seat includes occupants and objects, the first threshold is determined based on the items on the second seat and the age group of the occupants, and then the anti-pinch trigger condition is determined.
[0231] Step S1604: When the first pressure data meets the anti-pinch triggering condition, the seat controller performs an anti-pinch operation.
[0232] The anti-pinch operation is used to stop or reduce the squeezing damage to the occupants caused by the seat movement. The possible implementation methods of the anti-pinch operation are listed below as examples. In some schemes, the anti-pinch operation includes at least one of the following operations: controlling the target seat to stop moving, controlling the target seat to move in the opposite direction, and controlling the backrest of the first seat to adjust forward.
[0233] In some possible implementations, the anti-pinch operation can be implemented by sending a second instruction message to the seat adjustment motor to instruct the seat adjustment motor to perform the anti-pinch operation. Optionally, the second instruction message includes a motor drive signal, and the motor drive signal is used to instruct the seat adjustment motor to adjust a corresponding mileage to implement the anti-pinch operation.
[0234] In a possible implementation, controlling the target seat to stop moving represents controlling the target seat to stop the ongoing movement / adjustment action, including stopping the forward and backward movement of the target seat, and / or the forward and backward adjustment of the backrest of the target seat.
[0235] In a possible implementation manner, controlling the target seat to move in the opposite direction includes: controlling the target seat to move 10% of the movement range in the opposite direction to prevent further damage to the squeezed occupant.
[0236] The opposite direction mentioned above represents the opposite direction of the movement direction of the target seat before the anti-pinch triggering condition is met;
[0237] In some solutions of the above embodiments, controlling the target seat to move in the opposite direction includes controlling the first seat to move in the opposite direction. Fig.17 , Fig.17 A schematic diagram of a first seat moving backward provided in an embodiment of the present application. Fig.17 The current movement direction of the first seat is indicated in Fig.17 The first seat in the example is moving toward the rear of the seat, but if the first seat squeezes the occupant of the second seat when moving backward, the corresponding anti-pinch operation includes controlling the first seat to move in the opposite direction. In other words, the corresponding anti-pinch operation includes controlling the first seat to move forward. Correspondingly, the current movement direction of the first seat can also be forward, so the corresponding first pressure sensing module can be set at the seat cushion / leg support of the first seat to sense whether the forward movement of the first seat squeezes the occupant of the first seat, thereby controlling the first seat to move backward by 10%.
[0238] In the implementation mode of the present application, the movement mileage includes the total mileage of the target seat from the starting position to the current position, see Fig.18 , Fig.18 A schematic diagram of exercise mileage provided in an embodiment of the present application. Fig.18 The first seat in the figure starts from a starting position and moves toward the second seat. In the current position, the backrest of the first seat squeezes the occupant of the second seat. The first pressure data collected by the first pressure sensing module meets the anti-pinch trigger condition. In this process, the distance between the starting position and the current position is the movement mileage.
[0239] Optionally, the movement mileage also includes the total mileage of the target seat moving from the starting position to the target position, and the target position represents the position to which the seat is expected to move when the seat is "started with one button".
[0240] In some solutions, controlling the target seat to move in the opposite direction also includes controlling the second seat to move in the opposite direction, for example, controlling the second seat to move backward. During the forward movement of the second seat, an occupant sitting above the ground may be squeezed. When the first pressure data meets the anti-pinch trigger condition, the second seat is controlled to move backward by 10% of the movement mileage.
[0241] In another optional embodiment, controlling the target seat to move in the opposite direction includes: controlling the target seat to move in the opposite direction until the first pressure data does not satisfy the anti-pinch trigger condition. There are multiple situations in which the first pressure data does not satisfy the anti-pinch trigger adjustment, and the situation in which the first pressure data only includes the first pressure value is used as an example. The anti-pinch trigger condition corresponding to the first pressure value is that the first pressure value is greater than or equal to the first threshold value. Correspondingly, when the first pressure value is less than the first threshold value, the first pressure data does not satisfy the anti-pinch trigger condition, and there is no need to continue controlling the target seat to move in the opposite direction.
[0242] In this optional embodiment, the backrest of the first seat has an adjustment function. In the process of controlling the backrest of the first seat to adjust backward, the first seat may squeeze the occupant on the second seat. Correspondingly, the anti-pinch operation includes controlling the backrest of the first seat to adjust forward.
[0243] Further, controlling the backrest of the first seat to adjust forward includes: controlling the backrest of the first seat to adjust forward until the first pressure data does not meet the anti-pinch triggering condition.
[0244] In a possible embodiment, the first seat also includes a seat armrest, a leg rest and a foot rest. The surfaces of the seat armrest, the leg rest and the foot rest that are in contact with the occupant are respectively provided with a second pressure sensing module, a third pressure sensing module and a fourth pressure sensing module. The third pressure sensor, the fourth pressure sensor and the fifth pressure sensor are all used to collect pressure data to implement anti-pinch operations at corresponding positions. For example, when the seat armrest is rotating, the third pressure sensor arranged on the surface of the seat armrest that is in contact with the occupant senses that the occupant's hand is squeezed and transmits the data to the seat controller in real time. The seat controller implements the anti-pinch operation by adjusting the adjustment motor corresponding to the seat armrest. In this case, the anti-pinch operation is similar to the anti-pinch operation related to the first pressure sensing module.
[0245] In a possible implementation, when the anti-pinch operation is performed, first indication information is output to prompt the user the reason for performing the anti-pinch operation.
[0246] In one possible design, the above-mentioned vehicle can trigger reminders such as voice, light, electricity, vibration prompts, or display screens. For example, the vehicle may include modules that control outputs such as display processors, audio processors, and vibration processors (or the vehicle is connected to modules that control outputs), and the vehicle can output reminder signals to users through the above modules. Taking the display processor as an example, the reminder signal can trigger the display processor to present reminder signals, early warning information, etc. For example, the head up display (HUD) system in the vehicle can output a first reminder signal, which is used to remind the driver that the seat has been prohibited from continuing to expand / restore with one button. For another example, the above-mentioned first reminder signal can be presented by a vibration controller in the vehicle cabin area, and the user in the cabin can feel the vibration prompt.
[0247] Optionally, in some solutions, the above implementation is implemented when the seat is deployed and / or restored with one key. At this time, the reminder signal can also inform the user of the reason for prohibiting the seat from continuing to deploy / restore with one key. For example, the user is informed of the reason for stopping the one-key deployment of the seat through one or more prompting methods such as text display, voice broadcast, or vibration position prompt.
[0248] In the embodiment of the present application, the front, rear, left, right, up and down directions are defined based on the vehicle. The front and rear direction is the front and rear direction when the vehicle is moving forward, the left and right direction is the left and right direction of the vehicle, and the up and down direction is the up and down direction of the vehicle. Moreover, these directions are consistent with the front, rear, left, right, up and down directions of the driver. In addition, although the seat may have a variety of states or postures, unless otherwise specified, the directions of the seat or its components described herein refer to the directions in a state where the seat occupant faces forward and the seat backrest is approximately upright relative to the seat cushion.
