Description

Technical Field

[0001] The present invention relates to the technical field of intelligent adjustment of automobile seats, and in particular to an automatic adjustment system and method for front and rear seats of a multi-seat automobile, and a vehicle. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] With the development of smart cars, seat adjustment has become more intelligent and technological. At present, there are more and more models of multi-seat cars equipped with electric seats in the first, second and third rows, which provides more options for seat adjustment, and can provide the best riding experience for different numbers of passengers and different body shapes, adapting to different riding needs and scenarios. The layout of the seats is more flexible and changeable, which can enhance the technological sense of the whole vehicle and make it more intelligent.

[0004] However, most of the electric seats in smart cars currently still need to be adjusted manually. For example, when you need to adjust the front and rear space of the current seat, you still need to manually turn on the seat adjustment switch to adjust the front and rear position of the current seat, and even need to manually adjust the position of the seats in front and behind the current seat. The entire adjustment process is cumbersome and inefficient, and there are safety hazards during driving. Moreover, when the main driver changes, the seat still needs to be readjusted in the four directions of front, back, up and down. When multiple passengers change, all seats also need to be readjusted. This adjustment process is complicated and cumbersome. In addition, passengers still need to manually adjust the seat to a suitable angle for rest.

[0005] Although existing smart cars have applied technology for automatically adjusting seats based on identifying the body shapes of drivers and passengers, the current automatic seat adjustments are all performed on the seats in which the drivers and passengers are seated, that is, the adjustment process is performed for each single seat separately, and it is impossible to achieve automatic adjustment of all seats in the entire vehicle interior space, and manual adjustment of the positions of the front and rear seats of the current seat is still required. Summary of the invention

[0006] To address the deficiencies of the above-mentioned prior art, the present invention provides a system, method and vehicle for automatic adjustment of the front and rear seats of a multi-seat automobile. By monitoring the status of the driver and passengers in the vehicle and combining the actual situation of the vehicle, the front and rear positions of all seats in the entire interior space of the vehicle are automatically adjusted, the interior space layout is optimized, a more spacious activity space is provided for the driver and passengers, and the driving and riding comfort is improved.

In addition, it should also be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0052] Embodiment 1

[0053] This embodiment provides an automatic adjustment system for the front and rear seats of a multi-seat vehicle, which aims to realize intelligent adjustment of the positions of all seats in the vehicle without manual operation by passengers through a multi-module system algorithm, optimize the spatial layout of the seats in the vehicle, and provide a more comfortable riding environment for passengers. Figure 1 As shown, it includes a driver monitoring system 101, an occupant monitoring system 102, a seat belt controller 103, a vehicle controller 104, a multimedia host controller 201, a multimedia central control screen 202 (also referred to as a large screen), a driver's seat controller 301, a passenger seat controller 302, a second row left seat controller 303, a second row right seat controller 304, a third row left seat controller 305, and a third row right seat controller 306, wherein:

[0054] (1) Driver monitoring system (DMS), which is used to identify and obtain the physical characteristics and seating posture of the front driver in real time.

[0055] (2) Occupancy Monitoring System (OMS), which is used to identify and obtain in real time the number of all occupants, their seating positions, and each occupant’s physical characteristics, seating posture, and seating time.

[0056] The above-mentioned driver monitoring system DMS and occupant monitoring system OMS are both existing systems. Among them, DMS uses the camera inside the car to capture the physical characteristics video of the front driver, and determines the driver's physical characteristics (such as height, leg length, foot length, shoulder width, weight, etc.), and sitting posture (such as upper and lower limb posture and upper and lower limb activity space, etc.) after analyzing the video; while OMS uses the camera inside the car to capture the physical characteristics video of the occupants, and determines the occupants' physical characteristics and sitting posture after analyzing the video, and extracts the number of all occupants, seating positions and seating times.

[0057] In this embodiment, the physical characteristics include height, leg length, foot length, shoulder width, weight, etc. The information of height, leg length, foot length, shoulder width, etc. can be extracted and obtained through the vehicle-mounted camera combined with the image recognition algorithm, and the weight information can be obtained through the pressure sensor set on the driver's seat; the sitting posture includes the upper and lower limbs posture and the upper and lower limbs activity space, etc., which can be extracted and obtained through the vehicle-mounted camera combined with the image recognition algorithm.

[0058] Furthermore, the driver monitoring system 101 and the passenger monitoring system 102 are both electrically connected to the multimedia host controller 201 , and can transmit the identified and acquired information such as body features and seating posture to the multimedia host controller 201 .

[0059] (3) A seat belt controller, used to detect the seat belt plugging and unplugging status signal. Specifically, the seat belt controller 103 is electrically connected to the multimedia host controller 201, and sends the seat belt plugging and unplugging status signal to the multimedia host controller 201 via a CAN signal.

[0060] (4) Vehicle controller, used to detect the vehicle gear position signal. Specifically, the vehicle controller 104 is electrically connected to the multimedia host controller 201, and sends the vehicle gear position signal to the multimedia host controller 201 via a CAN signal.

[0061] (5) A multimedia central control screen, which is used to pop up the seat automatic adjustment switch option and generate the seat automatic adjustment switch signal. Specifically, the multimedia central control screen 202 is a touch screen, which is electrically connected to the multimedia host controller 201, and the multimedia central control screen 202 integrates the on / off control of all the seat automatic adjustment options in the vehicle, can display all the seat automatic adjustment switch options in the vehicle, and generate the seat automatic adjustment switch signal according to the user's touch selection, and then send the generated signal to the multimedia host controller 201.

[0062] (6) A multimedia host controller, which is used to generate corresponding adjustment instructions for each seat based on the physical characteristics and seating posture of the front driver, the seat belt insertion and removal status signal, the vehicle gear position signal, the automatic adjustment switch signal of the driver and passenger seats, the number of all passengers and the seating positions, as well as the physical characteristics, seating posture, and seating time of each passenger.

[0063] In the above system proposed in this embodiment, the driver monitoring system and the passenger monitoring system are used to identify the number of all drivers and passengers, the seat positions, the physical characteristics and the seat posture of each driver and passenger in the front row video and the second and third row videos, and transmit the identified information to the multimedia host controller as the main controller. The controller combines the seat belt plug-in status signal of the seat belt controller, the vehicle gear position signal of the vehicle controller, the main driver seat automatic adjustment switch signal of the multimedia central control screen, and the seat automatic adjustment switch signal fed back by each seat controller to generate a seat adjustment instruction, and then controls the front and rear position of each seat according to the adjustment instruction, so that the driver and passengers have the best riding space. Among them, it is limited that the front driver seat is prohibited from adjustment when it is not in P gear, and the main driver seat can not only be adjusted forward and backward, but also adjusted in height, so that the driver can quickly find the best driving position.

[0064] As an implementation method, the occupant monitoring system OMS can also identify and obtain the behavioral status of non-driving seat occupants. When it is identified that the non-driving seat occupant is resting or sleeping (for example, if it is detected that the passenger closes his eyes for more than a set time, it is considered that the passenger has entered a sleeping state), the signal is transmitted to the multimedia host controller 201 via a CAN signal. The multimedia host controller 201 generates an adjustment instruction to control the automatic adjustment of the passenger's seat back forward and backward, leg support, lumbar support, etc., so that the passenger has a more comfortable sitting posture.

[0065] (7) A seat controller, used to detect and generate an automatic adjustment switch signal for a passenger seat, and to adjust the position of the corresponding seat in the vehicle according to the seat adjustment command.

[0066] Specifically, the seat controller is electrically connected to the multimedia host controller 201, and the seat controller is electrically connected to the seat automatic adjustment button set on the corresponding seat. The user triggers the automatic adjustment of the seat by pressing the button. At this time, the seat controller detects and generates an automatic adjustment switch signal for the passenger seat, and transmits the signal to the multimedia host controller. The multimedia host controller determines whether to turn on the automatic adjustment function of the current seat based on the automatic adjustment switch signal for the passenger seat sent by the seat controller and the automatic adjustment switch signal for the seat sent by the multimedia central control screen, combined with the preset priority. In this embodiment, the priority of the automatic adjustment switch signal for the seat sent by the preset multimedia central control screen is higher than the automatic adjustment switch signal for the passenger seat sent by the seat controller.

[0067] Furthermore, each seat in a multi-seater car is provided with a corresponding seat controller, which includes a driver's seat controller and a passenger seat controller, wherein the seat adjustment instructions include seat height and front and back, seat back front and back, and lumbar support up and down and front and back adjustment instructions. According to the seat adjustment instructions, the driver's seat controller adjusts the front and back position and height position of the corresponding driver's seat, and the passenger seat controller adjusts the front and back position of the corresponding passenger seat.

[0068] like Figure 1 As shown, in this embodiment, taking a vehicle with three rows of seats as an example, a corresponding seat controller is set for each seat in each row, including a driver's seat controller 301, a passenger seat controller 302, a second row left seat controller 303, a second row right seat controller 304, a third row left seat controller 305, and a third row right seat controller 306, which automatically adjusts by receiving seat adjustment instructions issued by the multimedia host controller 201.

[0069] Embodiment 2

[0070] Based on the automatic adjustment system for front and rear seats of a multi-seat vehicle proposed in the first embodiment, this embodiment provides an automatic adjustment method for front and rear seats of a multi-seat vehicle, such as Figure 2 As shown, the specific steps include:

[0071] Step S1, after the driver gets into the vehicle and starts the vehicle, the physical characteristics and sitting posture of the front driver are identified and obtained in real time; wherein the physical characteristics include height, leg length, foot length, shoulder width, weight, etc., and the sitting posture includes the posture of upper and lower limbs and the activity space of upper and lower limbs, etc.;

[0072] Step S2, real-time monitoring of the driver's seat belt plug-in status signal and the vehicle gear position signal;

[0073] Step S3, generating a driver's seat forward and backward, height automatic adjustment instruction according to the front driver's physical characteristics and sitting posture, the driver's seat belt plug-in status signal, and the vehicle gear position signal, and then controlling the driver's seat controller according to the instruction to adjust the forward and backward, height position of the driver's seat in the vehicle;

[0074] Step S4: When passengers get on the bus and take their seats, the number of passengers, seat positions, and physical characteristics, seat posture, and seat time of all passengers are identified and obtained in real time;

[0075] Step S5: Generate a passenger seat forward and backward adjustment instruction based on the number of all passengers, seating positions, physical characteristics and seating posture of each passenger, combined with the passenger seat belt insertion and removal status signal, and control the passenger seat controller according to the instruction to adjust the forward and backward position of the passenger seat in the vehicle.

[0076] Specifically, in the above step S3, the multimedia host controller 201 may generate a driver's seat front and rear and height adjustment instruction, including:

[0077] S3.1. Obtain the front driver's physical characteristics, seating posture, vehicle gear position signal, and driver's seat belt insertion and removal status signal.

[0078] S3.2, determine whether the vehicle gear position signal and the driver's seat belt plug-in status signal meet the first setting condition, if so, control the multimedia central control screen to pop up the driver's seat automatic adjustment option to generate the driver's seat automatic adjustment switch signal. Among them, the first setting condition is: the vehicle gear position signal is P gear, and the driver's seat belt plug-in status signal is in the correct insertion state.

[0079] S3.3. Make a judgment based on the driver seat automatic adjustment switch signal. When the driver seat automatic adjustment switch signal is on, generate front and rear and height adjustment instructions for the driver seat position based on the front driver's body characteristics and sitting posture; conversely, when the driver seat automatic adjustment switch signal is off, stop the driver seat automatic adjustment function.

[0080] Specifically, the front driver monitoring system 101 can capture a video of the front driver's behavior, and by analyzing the front video, extract the driver's body characteristics such as height and leg length and sitting postures such as upper and lower limb postures and upper and lower limb activity space in the video. The multimedia host controller 201 pre-stores the optimal seat positions corresponding to a variety of body characteristics and sitting postures. The extracted body characteristics and sitting postures can be matched with the pre-stored body characteristics and sitting postures, and the optimal seat position can be determined based on the matching results. Then, based on the current seat position and the optimal seat position, the front and rear and height adjustment instructions of the main driver's seat position are generated and the main driver's seat is automatically adjusted accordingly.

[0081] In the above step S5, the multimedia host controller generates a passenger seat front and rear adjustment instruction, including:

[0082] S5.1. Obtain the number of all passengers, seat positions, physical characteristics, seat posture, seat time of each passenger, and seat belt insertion and removal status signals.

[0083] S5.2, determine whether the passenger seat belt plug-in status signal and the seating time meet the second setting condition. If so, control the multimedia audio system to make a voice announcement, and detect and generate the passenger seat automatic adjustment switch signal in real time. The second setting condition is: the passenger seat belt plug-in status signal is in the correct insertion state, and the seating time exceeds the preset time.

[0084] In this embodiment, for a vehicle with three rows of seats, the driver's seat is located on the left side of the first row, and each seat is provided with a corresponding seat controller and a corresponding seat automatic adjustment button. When the multimedia audio system broadcasts a voice reminder to the passenger that the seat automatic adjustment function can be selected, the seat automatic adjustment button is pressed within a set time (such as 30 seconds). At this time, the seat controller detects and generates a passenger seat automatic adjustment switch signal, thereby triggering the subsequent automatic adjustment of the seat forward and backward. Among them, the seat controller includes the driver's seat controller and the passenger seat controller. The above adjustment is only applicable to the passenger seat controller to avoid the safety risks caused by the driver adjusting the seat while driving.

[0085] like Figure 3 As shown, the multimedia central control screen 202 can also integrate the on and off control of all automatic adjustment options of seats in the vehicle. The automatic adjustment function of each seat can be turned on and off individually through the multimedia central control screen, and automatic seat adjustment switch signals for the driver and passengers are generated. This control has a higher priority than the control performed by the passengers through the seat adjustment buttons.

[0086] S5.3. Make a judgment based on the passenger seat automatic adjustment switch signal. When the passenger seat automatic adjustment switch signal is on, generate a fore-and-aft adjustment instruction for the passenger seat position based on the number of all passengers, the seating position, and the physical characteristics and seating posture of each passenger. Conversely, when the passenger seat automatic adjustment switch signal is off, stop the passenger seat automatic adjustment function.

[0087] Specifically, the occupant monitoring system 102 can capture the behavior video of all occupants in the vehicle, and by analyzing the video, extract the number of all occupants, seating positions, and the physical characteristics and seating posture of each occupant in the video. Similarly, the multimedia host controller 201 pre-stores the optimal vehicle seat positions corresponding to various situations with different numbers of occupants, seating positions, and different physical characteristics and seating postures of the occupants. This can be used to match the extracted information to determine the optimal vehicle seat position, and then generate fore and aft adjustment instructions for the vehicle seat position based on the current vehicle seat position and the optimal vehicle seat position, and automatically adjust the corresponding seats.

[0088] Take a vehicle with three rows of seats as an example. Figure 4 As shown in the figure, the adjustment strategy for adjusting the front and rear seats of the vehicle to the optimal space is: first, when there is someone in the main driver's seat, the front and rear and height positions of the main driver's seat are automatically adjusted according to the main driver's seat adjustment instructions; then, according to the passenger seat adjustment instructions, the front and rear positions of the passenger seats are adjusted. The adjustment process includes:

[0089] (1) When a passenger sits in the left side of the second row, the left side seats of the second and third rows, except the driver's seat, will automatically adjust backwards; then, if a passenger sits in the right side of the second row, the right side seats of the first row will automatically adjust forwards, and the right side seats of the second and third rows will automatically adjust backwards;

[0090] (2) When a passenger sits on the left side of the third row, the left side seats in the second row, except for the driver's seat, will automatically adjust forward and the left side seats in the third row will automatically adjust backward. After that, if a passenger sits on the right side of the third row, the right side seats in the first and second rows will automatically adjust forward and the right side seats in the third row will automatically adjust backward.

[0091] The above adjustment process is only an example of several situations, and the automatic adjustment of the seat position of the entire vehicle can be carried out according to specific circumstances.

[0092] As another implementation method, the occupant monitoring system OMS can also identify and obtain the behavioral status of non-driving passengers. When it is identified that the non-driving passenger falls asleep, the signal is transmitted to the multimedia host controller via CAN. The multimedia host controller generates an adjustment instruction to control the automatic adjustment of the passenger's seat back, leg support, lumbar support, etc., so that the passenger has a more comfortable sitting posture.

[0093] Through the above method, it is possible to ensure that the driver's legs have appropriate stretching space according to the body shape of different drivers, avoid leg fatigue and numbness during long-term driving, and the automatic adjustment of the seat height can allow the driver to obtain a good field of vision, better observe the road conditions, and improve driving safety. The automatic adjustment of the seat can effectively enhance human-computer interaction and improve work efficiency, and adjustment is prohibited in non-P gears, which can effectively improve driving safety; when it is recognized that a passenger in a non-driving position is preparing to sleep, the automatic adjustment of the backrest, leg support, lumbar support, etc. can be controlled to make the passenger have a more comfortable sitting posture. By automatically adjusting the seat, human-computer interaction is further enhanced and work efficiency is improved; when it is recognized which positions have people, the front and rear distance of the seats of the entire vehicle can be automatically adjusted to provide each passenger with a more comfortable riding space, which can effectively enhance human-computer interaction, improve work efficiency, and enhance the sense of technology of the entire vehicle.
