Description

Technical Field

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

[0002] With the continuous development of vehicle technology and the further improvement of people's demand for riding comfort, zero-gravity seats are installed in vehicles to improve the riding comfort of passengers. When the zero-gravity seat is in zero-gravity mode, the seat can make the passengers present a nearly lying sitting posture, so that the spine is naturally relaxed, and the pressure on the body is dispersed and balanced as much as possible, reducing muscle wear and tear, ensuring constant blood flow, and creating a relaxed feeling of weightlessness, which makes the passengers feel energetic even after a long drive.

[0003] However, in order to ensure the safety of passengers, existing safety protection measures control the zero-gravity mode of the zero-gravity seat in a turned-off state during the driving of the vehicle. Passengers cannot use the zero-gravity mode to improve riding comfort, which reduces the passengers' riding experience. Summary of the invention

[0004] In view of the above, the embodiments of the present application provide a seat control method, a controller, a seat control system and a vehicle. During the driving of the vehicle, the passengers can also turn on the zero-gravity mode of the zero-gravity seat, which improves the passengers' riding experience and ensures the safety of the passengers.

[0005] An embodiment of the present application provides a seat control method, which is applied to a vehicle, wherein the vehicle includes a zero-gravity seat, and the method includes: during the driving of the vehicle, if the zero-gravity seat is in the zero-gravity mode and there is a passenger sitting in the zero-gravity seat, detecting whether there is an obstacle within a preset range of the vehicle, wherein when the zero-gravity seat is in the zero-gravity mode, the passenger sitting in the zero-gravity seat is in a weightless state; when it is detected that there is the obstacle within the preset range of the vehicle, determining whether there is a safety risk in the vehicle; when the safety risk exists between the vehicle and the obstacle, adjusting the working mode of the zero-gravity seat from the zero-gravity mode to the safety mode, wherein when the zero-gravity seat is in the safety mode, the passenger sitting in the zero-gravity seat is in a non-weightless state.

[0006] Compared with the related art, the embodiments of the present application have at least the following advantages: During the driving process of the vehicle, if the zero-gravity seat is in zero-gravity mode and there are passengers in the zero-gravity seat, detect whether there are obstacles within the preset range of the vehicle. When an obstacle is detected within the preset range of the vehicle, in order to avoid collision damage to passengers in the zero-gravity seat when a safety accident occurs between the obstacle and the vehicle, it is necessary to determine whether the vehicle has a safety risk. When it is determined that there is a safety risk to the vehicle, it indicates that there may be a safety accident between the vehicle and the obstacle, and a collision may occur between the obstacle and the vehicle, resulting in damage to the passengers. In order to ensure the personal safety of the passengers, the zero-gravity seat is adjusted from zero-gravity mode to safety mode, thereby minimizing collision damage to the passengers as much as possible. At the same time, passengers can also use the zero-gravity mode during the driving of the vehicle, which improves the passengers' riding experience.

[0007] In some possible implementations, determining whether the vehicle presents a safety risk includes: obtaining a collision probability and an expected collision time between the vehicle and the obstacle; when the collision probability is greater than a preset probability threshold and the expected collision time is less than a preset time threshold, obtaining the current driving speed of the vehicle and an expected collision overlap rate between the vehicle and the obstacle, the expected collision overlap rate being a ratio between an expected collision width and a vehicle width of the vehicle, the expected collision width being a width value of a collision surface when a collision is expected to occur between the vehicle and the obstacle; determining whether the vehicle presents the safety risk based on the driving speed and the expected collision overlap rate.

[0008] In some possible implementations, determining whether the vehicle has the safety risk based on the driving speed and the expected collision overlap rate includes: detecting whether the driving speed is greater than or equal to a preset vehicle speed threshold and whether the expected collision overlap rate is greater than or equal to a preset overlap threshold; when it is detected that the driving speed is greater than or equal to the preset vehicle speed threshold and the expected collision overlap rate is greater than or equal to the preset overlap threshold, determining that the vehicle has the safety risk.

[0009] In some possible implementations, after detecting whether the driving speed is greater than or equal to a preset vehicle speed threshold and whether the expected collision overlap rate is greater than or equal to a preset overlap threshold, it also includes: when it is detected that the driving speed is less than the preset vehicle speed threshold and the expected collision overlap rate is greater than or equal to the preset overlap threshold, obtaining the relative speed between the vehicle and the obstacle; detecting whether the relative speed is greater than or equal to a preset relative speed threshold; and determining that the vehicle has the safety risk when it is detected that the relative speed is greater than or equal to the preset relative speed threshold.

[0010] In some possible implementations, obtaining the estimated collision time between the vehicle and the obstacle includes: obtaining a relative distance and a relative speed between the vehicle and the obstacle; and using a ratio of the relative distance to the relative speed as the estimated collision time.

[0011] In some possible implementations, the zero-gravity seat includes a backrest frame, which is used to support the upper body of the occupant; when the zero-gravity seat is in the safety mode, a first angle between the backrest frame and the ground is within a first preset range, and the first preset range is greater than or equal to 30° and less than or equal to 52°.

[0012] In some possible implementations, the zero-gravity seat also includes a seat cushion frame, which is used to support the lower body of the occupant; when the zero-gravity seat is in the safety mode, a second angle between the seat cushion frame and the ground is within a second preset range, and the second preset range is greater than or equal to 10° and less than or equal to 25°. A second aspect of the present application discloses a controller, which includes a processor and a memory, wherein the memory is used to store instructions, and the processor is used to call the instructions in the memory so that the controller executes the seat control method as described above.

[0013] A third aspect of the present application discloses a seat control system, including a zero-gravity seat and the controller as described above.

[0014] A fourth aspect of the present application discloses a vehicle, comprising the seat control system as described above.

[0015] It can be understood that the controller of the second aspect, the seat control system of the third aspect and the vehicle of the fourth aspect provided above all correspond to the method of the first aspect. Therefore, the beneficial effects that can be achieved can refer to the beneficial effects in the corresponding methods provided above and will not be repeated here.

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

[0025] With the continuous development of vehicle technology and the further improvement of people's demand for riding comfort, zero-gravity seats are installed in vehicles to improve the riding comfort of passengers. When the zero-gravity seat is in zero-gravity mode, the seat can make the passengers present a nearly lying sitting posture, so that the spine is naturally relaxed, and the pressure on the body is dispersed and balanced as much as possible, reducing muscle wear and tear, ensuring constant blood flow, and creating a relaxed feeling of weightlessness, which makes the passengers feel energetic even after a long drive.

[0026] However, in order to ensure the safety of passengers, the existing safety protection measures are to turn off the zero-gravity mode of the zero-gravity seat during the driving process of the vehicle, and passengers cannot use the zero-gravity mode to improve riding comfort, which reduces the passengers' riding experience. Alternatively, the vehicle can only be controlled to drive at a low speed, and the zero-gravity mode of the zero-gravity seat cannot be used when the vehicle is driving at a high speed.

[0027] Based on this, the embodiment of the present application provides a seat control method, which is applied to a seat control system. The seat control system can be configured in a vehicle, and the vehicle can include a new energy vehicle, a fuel vehicle, an engineering vehicle, etc. The present application does not limit the type of vehicle.

[0028] like Figure 1 As shown, the seat control system includes a controller 100 and a zero-gravity seat 200. The controller 100 and the zero-gravity seat 200 are connected wirelessly or wired, and the controller 100 is used to control the opening and closing of the zero-gravity mode of the zero-gravity seat 200.

[0029] Specifically, the seat control method is applied to the controller 100. In this embodiment, the controller 100 may include a processor and a memory. The memory is used to store one or more computer programs. The one or more computer programs are configured to be executed by the processor. The one or more computer programs include instructions, and the above instructions can be used to implement the seat control method in the controller.

[0030] In this embodiment, the zero gravity chair 200 includes a backrest frame 21, a backrest driving member 22, a cushion frame 23 and a cushion driving member 24. The backrest frame 21 is rotatably connected to the cushion frame 23. The backrest driving member 22 is located inside the backrest frame 21. The backrest driving member 22 is driven to connect to the backrest frame 21, and the backrest driving member 22 is used to drive the first angle between the backrest frame 21 and the ground, and the backrest frame 21 is used to support the upper body of the occupant. The cushion driving member 24 is located inside the cushion frame 23. The cushion driving member 24 is driven to connect to the cushion frame 23, and the cushion driving member 24 is used to drive the second angle between the cushion frame 23 and the ground, and the cushion frame 23 is used to support the lower body of the occupant. Among them, the backrest driving component 22 and the seat cushion driving component 24 are both driving motors. In other embodiments, the backrest driving component 22 and the seat cushion driving component 24 can also be driving components other than driving motors. For example, the backrest driving component 22 and the seat cushion driving component 24 can also be inflatable devices. The types of the backrest driving component 22 and the seat cushion driving component 24 can be the same or different, and the present application does not limit this.

[0031] Please refer to Figure 2 , is a flow chart of a seat control method provided in an embodiment of the present application. The seat control method comprises the following steps: Step 101: During the driving process of the vehicle, if the zero-gravity seat is in the zero-gravity mode and there is a passenger in the zero-gravity seat, detect whether there is an obstacle within a preset range of the vehicle.

[0032] In this embodiment, a first acquisition component may be provided in the vehicle, and an image or video containing the zero-gravity seat 200 may be acquired through the first acquisition component, and the image or video may be processed to determine whether there is an occupant in the zero-gravity seat 200. The first acquisition component may be a camera or a camera head. Alternatively, a seat sensor may be provided in the zero-gravity seat 200, and the seat sensor may be used to detect whether there is an occupant in the zero-gravity seat 200. The seat sensor may be a pressure sensor or a seat belt reminder. The present application does not limit the types of the first acquisition component and the seat sensor.

[0033] In some embodiments, if the zero gravity mode of the zero gravity chair 200 is in the on state, it indicates that the zero gravity chair 200 is in the zero gravity mode. Wherein, when the zero gravity chair 200 is in the zero gravity mode, the occupant sitting in the zero gravity chair 200 is in a weightless state. If the zero gravity mode of the zero gravity chair 200 is in the off state, it indicates that the zero gravity chair 200 is in a non-zero gravity mode.

[0034] Further, it is detected whether there is an obstacle within the preset range of the vehicle, wherein a second acquisition component can be set on the vehicle, and the surrounding environment information of the vehicle is collected by the second acquisition component, and whether there is an obstacle within the preset range of the vehicle is determined based on the surrounding environment information. The second acquisition component can be a camera or a radar, and this application does not limit it.

[0035] The preset range may be a circular range formed by taking the vehicle as the center and the preset length as the radius, or a quadrilateral range formed by taking the vehicle as the center and the preset length and preset width. The preset length may be 5 meters or 6 meters, and the preset width may be 3 meters or 4 meters. The present application does not limit the specific values ​​of the preset length and preset width and the specific shape of the preset range. That is to say, in other embodiments, the shape of the preset range may also be a triangle, a pentagon, or an irregular shape, etc.

[0036] Step 102: When an obstacle is detected within a preset range of the vehicle, determine whether the vehicle has a safety risk.

[0037] In this embodiment, the specific steps of determining whether the vehicle has a safety risk include: Obtain the collision probability and expected collision time between the vehicle and the obstacle. When the collision probability is greater than the preset probability threshold and the expected collision time is less than the preset time threshold, obtain the current driving speed of the vehicle and the expected collision overlap rate between the vehicle and the obstacle. The expected collision overlap rate is the ratio between the expected collision width and the vehicle width of the vehicle. The expected collision width is the width of the collision surface when a collision is expected between the vehicle and the obstacle. Based on the driving speed and the expected collision overlap rate, determine whether the vehicle poses a safety risk. Among them, the preset probability threshold may be 65%, 70% or 75%, and the preset time threshold may be 2s, 2.5s or 3s. The present application does not limit the specific values ​​of the preset probability threshold and the preset time threshold.

[0038] In this embodiment, the step of obtaining the estimated collision time between the vehicle and the obstacle includes: obtaining the relative distance and relative speed between the vehicle and the obstacle, and taking the ratio of the relative distance and the relative speed as the estimated collision time.

[0039] In this embodiment, the collision probability between the vehicle and the obstacle can be directly obtained from other systems in the vehicle. For example, the other system may be an intelligent driving system. This application does not limit the method of obtaining the collision probability.

[0040] Further, based on the driving speed and the expected collision overlap rate, the step of determining whether the vehicle has a safety risk includes: Detect whether the driving speed is greater than or equal to the preset speed threshold and whether the predicted collision overlap rate is greater than or equal to the preset overlap threshold. When it is detected that the driving speed is greater than or equal to the preset speed threshold and the predicted collision overlap rate is greater than or equal to the preset overlap threshold, it indicates that the current speed of the vehicle is fast, the predicted collision area between the vehicle and the obstacle is large, and it is determined that the vehicle has a safety risk. Among them, the preset speed threshold can be 35km / h or 40km / h, and the preset overlap threshold can be 25%, 28% or 30%. This application does not limit the specific values ​​of the preset speed threshold and the preset overlap threshold.

[0041] When it is detected that the driving speed is less than the preset vehicle speed threshold and the expected collision overlap rate is greater than or equal to the preset overlap threshold, the relative speed between the vehicle and the obstacle is obtained. Whether the relative speed is greater than or equal to the preset relative speed threshold is detected. When it is detected that the relative speed is greater than or equal to the preset relative speed threshold, it is determined that the vehicle has a safety risk. When it is detected that the relative speed is less than the preset relative speed threshold, it is determined that the vehicle does not have a safety risk.

[0042] In another embodiment, based on the driving speed and the expected collision overlap rate, the step of determining whether the vehicle has a safety risk may further include: The relative speed between the vehicle and the obstacle is obtained, and it is detected whether the relative speed is greater than or equal to a preset relative speed threshold and whether the expected collision overlap rate is greater than or equal to a preset overlap threshold. When it is detected that the relative speed is greater than or equal to the preset relative speed threshold and the expected collision overlap rate is greater than or equal to the preset overlap threshold, it indicates that the relative speed is fast, the predicted collision area between the vehicle and the obstacle is large, and it is determined that the vehicle has a safety risk. When it is detected that the relative speed is less than the preset relative speed threshold and the expected collision overlap rate is greater than or equal to the preset overlap threshold, it is detected whether the driving speed is greater than or equal to the preset vehicle speed threshold. When it is detected that the driving speed is greater than or equal to the preset vehicle speed threshold, it indicates that the current vehicle speed of the vehicle is fast, and it is determined that the vehicle has a safety risk. When it is detected that the driving speed is less than the preset vehicle speed threshold, it indicates that the current vehicle speed and the speed of the obstacle are both slow, and it is determined that the vehicle does not have a safety risk.

[0043] In this embodiment, the driving speed, relative speed and expected collision overlap rate are all detected, and through the detection results, it can be accurately determined whether the vehicle has a safety risk.

[0044] Step 103: When there is a safety risk to the vehicle, adjust the working mode of the zero-gravity seat from the zero-gravity mode to the safety mode.

[0045] In some embodiments, when the zero-gravity chair 200 is in a safety mode, the occupant sitting in the zero-gravity chair 200 is in a non-weightless state. For example, when the zero-gravity chair 200 is in a safety mode, the occupant sitting in the zero-gravity chair 200 is in a semi-reclining state or a sitting state. Specifically, in this embodiment, when the zero-gravity chair 200 is in a safety mode, the controller 100 controls the backrest drive 22 to drive the backrest frame 21 to rotate relative to the cushion frame 23, so that the first angle between the backrest frame 21 and the ground is within a first preset range, and the first preset range is greater than or equal to 30° and less than or equal to 52°. For example, the first angle can be 30°, 32°, 35°, 38°, 40°, 45° and 50°. The controller 100 controls the cushion drive 24 to drive the cushion frame 23 to rotate relative to the backrest frame 21, so that the second angle between the cushion frame 23 and the ground is within a second preset range, and the second preset range is greater than or equal to 10° and less than or equal to 25°. For example, the second angle can be 12°, 15°, 18°, 20° and 23°. The present application does not limit the specific values ​​of the first angle and the second angle, which can be set according to actual circumstances.

[0046] It should be noted that the setting of the first preset range and the second preset range, on the one hand, when the zero-gravity seat 200 is adjusted from the zero-gravity mode to the safety mode, so that the occupant is adjusted from the weightless state to the non-weightless state, the angle range of the backrest frame 21 and the seat cushion frame 23 is small, and the occupant will not feel obvious discomfort during the adjustment. On the other hand, when a collision occurs between the vehicle and an obstacle, the occupant in the non-weightless state can be protected by the airbag to the maximum extent, so that the collision damage to the occupant when the vehicle and the obstacle collide can be reduced as much as possible.

[0047] In other embodiments, when the zero-gravity chair 200 is in the safety mode, the occupant sitting in the zero-gravity chair 200 may also be placed in a sitting position. When the zero-gravity chair 200 is in the safety mode, the present application does not restrict the position of the occupant sitting in the zero-gravity chair 200.

[0048] Compared with the related art, the embodiments of the present application have at least the following advantages: During the driving process of the vehicle, if the zero-gravity seat is in zero-gravity mode and there are passengers in the zero-gravity seat, detect whether there are obstacles within the preset range of the vehicle. When an obstacle is detected within the preset range of the vehicle, in order to avoid collision damage to passengers in the zero-gravity seat when a safety accident occurs between the obstacle and the vehicle, it is necessary to determine whether the vehicle has a safety risk. When it is determined that there is a safety risk to the vehicle, it indicates that there may be a safety accident between the vehicle and the obstacle, and a collision may occur between the obstacle and the vehicle, resulting in damage to the passengers. In order to ensure the personal safety of the passengers, the zero-gravity seat is adjusted from zero-gravity mode to safety mode, thereby minimizing collision damage to the passengers as much as possible. At the same time, passengers can also use the zero-gravity mode during the driving of the vehicle, which improves the passengers' riding experience.

[0049] Please refer to Figure 3 , is an interactive schematic diagram of a seat control system provided in an embodiment of the present application. The specific contents are as follows: Step S1: During the driving process of the vehicle, if the zero-gravity seat is in the zero-gravity mode and there is a passenger sitting in the zero-gravity seat, the controller detects whether there is an obstacle within a preset range of the vehicle.

[0050] In this embodiment, a first acquisition component may be provided in the vehicle, and an image or video containing the zero-gravity seat 200 may be acquired through the first acquisition component, and the image or video may be processed to determine whether there is an occupant in the zero-gravity seat 200. The first acquisition component may be a camera or a camera head. Alternatively, a seat sensor may be provided in the zero-gravity seat 200, and the seat sensor may be used to detect whether there is an occupant in the zero-gravity seat 200. The seat sensor may be a pressure sensor or a seat belt reminder. The present application does not limit the types of the first acquisition component and the seat sensor.

[0051] In some embodiments, if the zero gravity mode of the zero gravity chair 200 is in the on state, it indicates that the zero gravity chair 200 is in the zero gravity mode. Wherein, when the zero gravity chair 200 is in the zero gravity mode, the occupant sitting in the zero gravity chair 200 is in a weightless state. If the zero gravity mode of the zero gravity chair 200 is in the off state, it indicates that the zero gravity chair 200 is in a non-zero gravity mode.

[0052] Further, it is detected whether there is an obstacle within the preset range of the vehicle, wherein a second acquisition component can be set on the vehicle, and the surrounding environment information of the vehicle is collected by the second acquisition component, and whether there is an obstacle within the preset range of the vehicle is determined based on the surrounding environment information. The second acquisition component can be a camera or a radar, and this application does not limit it.

[0053] The preset range may be a circular range formed by taking the vehicle as the center and the preset length as the radius, or a quadrilateral range formed by taking the vehicle as the center and the preset length and preset width. The preset length may be 5 meters or 6 meters, and the preset width may be 3 meters or 4 meters. The present application does not limit the specific values ​​of the preset length and preset width and the specific shape of the preset range. That is to say, in other embodiments, the shape of the preset range may also be a triangle, a pentagon, or an irregular shape, etc.

[0054] Step S2: When the controller detects an obstacle within a preset range of the vehicle, it determines whether the vehicle has a safety risk.

[0055] The specific steps for determining whether a vehicle has a safety risk are described in detail above and will not be repeated here.

[0056] Step S3: When there is a safety risk to the vehicle, the controller sends a safety adjustment instruction to the zero-gravity seat.

[0057] In some embodiments, the safety adjustment instruction is used to adjust the working mode of the zero-gravity seat 200 from the zero-gravity mode to the safety mode to reduce collision damage to the occupants when the vehicle collides with an obstacle.

[0058] Step S4: The zero-gravity chair adjusts its working mode from the zero-gravity mode to the safety mode.

[0059] In this embodiment, after receiving the safety adjustment instruction, the zero-gravity chair 200 controls the backrest drive 22 to drive the backrest frame 21 to rotate relative to the cushion frame 23, so that the first angle between the backrest frame 21 and the ground is within a first preset range, and the first preset range is greater than or equal to 30° and less than or equal to 52°. For example, the first angle can be 30°, 32°, 35°, 38°, 40°, 45° and 50°. And, the zero-gravity chair 200 controls the cushion drive 24 to drive the cushion frame 23 to rotate relative to the backrest frame 21, so that the second angle between the cushion frame 23 and the ground is within a second preset range, and the second preset range is greater than or equal to 10° and less than or equal to 25°. For example, the second angle can be 12°, 15°, 18°, 20° and 23°. The present application does not limit the specific values ​​of the first angle and the second angle, and they can be set according to actual conditions.

[0060] Compared with the related art, this embodiment has at least the following advantages: During the driving process of the vehicle, if the zero-gravity seat is in zero-gravity mode and there are passengers in the zero-gravity seat, detect whether there are obstacles within the preset range of the vehicle. When an obstacle is detected within the preset range of the vehicle, in order to avoid collision damage to passengers in the zero-gravity seat when a safety accident occurs between the obstacle and the vehicle, it is necessary to determine whether the vehicle has a safety risk. When it is determined that there is a safety risk to the vehicle, it indicates that there may be a safety accident between the vehicle and the obstacle, and a collision may occur between the obstacle and the vehicle, resulting in damage to the passengers. In order to ensure the personal safety of the passengers, the zero-gravity seat is adjusted from zero-gravity mode to safety mode, thereby minimizing collision damage to the passengers as much as possible. At the same time, passengers can also use the zero-gravity mode during the driving of the vehicle, which improves the passengers' riding experience.

The memory may store instructions or data that the processor has just used or is cyclically used. If the processor needs to use the instruction or data again, it may be directly called from the memory.

[0066] In some embodiments, the memory may include a high-speed random access memory and may also include a non-volatile memory, such as a hard disk, a memory, a plug-in hard disk, a Smart Media Card (SMC), a Secure Digital (SD) card, a flash card (Flash Card), at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.
