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

[0003] With the development of intelligent automobiles, seat adjustment is more intelligent and technological. At present, more and more vehicle models are equipped with electric seats for the first, second and third rows of seats, which provides more options for front and rear seat adjustment, can provide the best riding experience for different numbers of passengers and different body types of passengers, adapt to different riding needs and scenarios, and the layout of the seats is more flexible and variable, which can improve the technological sense of the whole vehicle and make it more intelligent.

[0004] However, most of the electric seats in current intelligent automobiles still need to be adjusted manually. For example, when the front and rear space of the current seat needs to be adjusted, the seat adjustment switch still needs to be manually turned on to adjust the front and rear position of the current seat, and even the position of the seat in front of the current seat needs to be manually adjusted. The whole adjustment process is complicated and inefficient, and there is a safety hazard during driving. Moreover, when the driver changes, the front and rear and four directions of the seat need to be adjusted again, and when multiple passengers change, all the seats need to be adjusted again, which is a complicated and tedious process. In addition, the passengers still need to manually adjust the seat to the appropriate angle for rest.

[0005] Although there are technologies in current intelligent automobiles that automatically adjust the seat according to the identification of the body size of the driver and passengers, the current automatic adjustment of the seat is only for the seat where the driver and passengers sit, i.e. the adjustment process is for each single seat, which cannot realize the automatic adjustment of all seats in the whole vehicle space, and still needs to manually adjust the position of the front and rear seats of the current seat.

[0052] Embodiment One

[0053] The present embodiment provides a multi-seat vehicle front and rear seat automatic adjustment system, which aims to realize intelligent adjustment of the positions of all seats in the vehicle without manual operation through a multi-module system algorithm, optimize the spatial layout of the seats in the vehicle, and provide a more comfortable riding environment for the passengers. The automatic adjustment system proposed in the present embodiment, as shown in Figure 1 Fig. 1, includes a driver monitoring system 101, a passenger monitoring system 102, a seat belt controller 103, a vehicle controller 104, a multimedia host controller 201, a multimedia center screen 202 (also referred to as a large screen), a main driver seat controller 301, a co-driver 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), used for real-time identification and acquisition of the physical characteristics and seating posture of the front-row driver.

[0055] (2) Occupancy Monitoring System (OMS), used for real-time identification and acquisition of the number of passengers, seating positions, and physical characteristics, seating posture, and seating time of each passenger.

[0056] The driver monitoring system DMS and the occupant monitoring system OMS are both existing systems. The DMS captures the video of the physical features of the driver in the front row through the in-vehicle camera, determines the physical features (such as height, leg length, foot length, shoulder width, weight, etc.) and the seating posture (such as the posture of the upper and lower limbs and the activity space of the upper and lower limbs, etc.) of the driver after analyzing the video; and the OMS captures the video of the physical features of the occupants through the in-vehicle camera, determines the physical features and the seating posture of the occupants after analyzing the video, and extracts the number, seating position and seating time of all the occupants.

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

[0058] Further, the driver monitoring system 101 and the occupant monitoring system 102 are electrically connected with the multimedia host controller 201, and can transmit the information of the recognized and obtained physical features and seating posture to the multimedia host controller 201.

[0059] (3) The seat belt controller is used for detecting the seat belt plug-in state signal. Specifically, the seat belt controller 103 is electrically connected with the multimedia host controller 201, and sends the seat belt plug-in state signal to the multimedia host controller 201 through the CAN signal.

[0060] (4) The vehicle controller is used for detecting the vehicle gear signal. Specifically, the vehicle controller 104 is electrically connected with the multimedia host controller 201, and sends the vehicle gear signal to the multimedia host controller 201 through the CAN signal.

[0061] (5) The multimedia center control screen is used for popping up the seat automatic adjustment switch options and generating the seat automatic adjustment switch signal. Specifically, the multimedia center control screen 202 is a touch screen, which is electrically connected with the multimedia host controller 201, and the multimedia center control screen 202 is integrated with the on-off control of all seat automatic adjustment options in the vehicle, can display all seat automatic adjustment switch options in the vehicle, and generate the seat automatic adjustment switch signal according to the touch selection of the user, and then send the generated signal to the multimedia host controller 201.

[0062] (6) A multimedia host controller for generating a corresponding adjustment instruction for each seat according to the body features and seating posture of the front driver, the seat belt plug-in state signal, the vehicle gear signal, the automatic adjustment switch signal of the driver and passenger seats, the number and seating position of all passengers, and the body features, seating posture, and seating time of each passenger.

[0063] In the above system, the driver monitoring system and the passenger monitoring system are used to identify the number, seating position, body features, and seating posture of each passenger in the front 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 state signal of the seat belt controller, the vehicle gear signal of the vehicle controller, the automatic adjustment switch signal of the driver seat of the multimedia center screen, and the automatic adjustment switch signal of each seat controller to generate a seat adjustment instruction, and controls the front and rear positions of each seat according to the adjustment instruction to provide the driver and passengers with the best seating space. In this embodiment, the front driver seat is prohibited from being adjusted in the non-P gear, and the driver seat can be adjusted in the front and rear positions as well as the height, which can quickly find the best driving position for the driver.

[0064] As an implementation manner, the passenger monitoring system OMS can also identify and obtain the behavior state of the passenger in the non-driving position. When it is identified that the passenger in the non-driving position is resting or sleeping (e.g., it is detected that the passenger closes his eyes for more than a set time, and it is considered that the passenger enters a sleeping state), the signal is transmitted to the multimedia host controller 201 through the CAN signal, the multimedia host controller 201 generates an adjustment instruction, and controls the automatic adjustment of the passenger seat back, leg support, waist support, etc., to make the passenger have a more comfortable sitting posture.

[0065] (7) A seat controller for detecting and generating a passenger seat automatic adjustment switch signal, and adjusting the position of the corresponding seat in the vehicle according to the seat adjustment instruction.

[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 arranged 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 a passenger seat automatic adjustment switch signal, and transmits the signal to the multimedia host controller. The multimedia host controller judges whether to start the automatic adjustment function of the current seat according to the passenger seat automatic adjustment switch signal sent by the seat controller and the seat automatic adjustment switch signal sent by the multimedia center screen in combination with the preset priority. In this embodiment, the priority of the seat automatic adjustment switch signal sent by the multimedia center screen is higher than that of the passenger seat automatic adjustment switch signal sent by the seat controller.

[0067] Furthermore, each seat in the multi-seat vehicle is equipped with a corresponding seat controller, which includes a driver's seat controller and a passenger seat controller. The seat adjustment commands include adjustments for seat height and fore-aft position, seat back fore-aft position, and lumbar support height and fore-aft position. According to the seat adjustment commands, the driver's seat controller adjusts the fore-aft and height positions of the corresponding driver's seat, and the passenger seat controller adjusts the fore-aft 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 driver's seat controller 301, passenger seat controller 302, second-row left seat controller 303, second-row right seat controller 304, third-row left seat controller 305, and third-row right seat controller 306. These controllers automatically adjust the seats by receiving seat adjustment commands from the multimedia host controller 201.

[0069] Example 2

[0070] Based on the multi-seat car front and rear seat automatic adjustment system proposed in Embodiment 1 above, this embodiment provides a method for automatic adjustment of the front and rear seats of a multi-seat car, such as... Figure 2 As shown, the specific steps include:

[0071] Step S1: After the driver gets into the car and starts the vehicle, the body characteristics and sitting posture of the driver in the front row are identified and obtained in real time. Among them, the body characteristics include height, leg length, foot length, shoulder width, weight, etc., and the sitting posture includes upper and lower limb posture and upper and lower limb movement space, etc.

[0072] Step S2: Real-time monitoring of the driver's seatbelt insertion / removal status signal and the vehicle's gear position signal;

[0073] Step S3: Based on the body characteristics and sitting posture of the front driver, the driver's seat belt insertion / removal status signal, and the vehicle gear position signal, generate automatic adjustment commands for the fore-aft and height of the driver's seat, and then control the driver's seat controller according to the commands to adjust the fore-aft and height position of the driver's seat in the vehicle.

[0074] Step S4: After passengers board the vehicle and take their seats, the number of passengers, their seating positions, and the physical characteristics, sitting posture, and sitting time of each passenger are identified and obtained in real time.

[0075] Step S5: Based on the number of all occupants, their seating positions, and the physical characteristics and seating posture of each occupant, combined with the seat belt insertion / removal status signal, generate a command to adjust the fore-and-aft position of the occupant seat. Control the occupant seat controller according to the command to adjust the fore-and-aft position of the occupant seat in the vehicle.

[0076] Specifically, in the step S3, the multimedia host controller 201 can generate the front-rear and height-adjustment instructions of the driver's seat, including:

[0077] S3.1, obtaining the body features and seating posture of the front driver, and the gear signal and the driver's seatbelt insertion state signal.

[0078] S3.2, judging whether the gear signal and the driver's seatbelt insertion state signal meet the first set condition, if yes, controlling the multimedia center screen to pop up the driver's seat automatic adjustment option to generate the driver's seat automatic adjustment switch signal. The first set condition is that the gear signal is P gear and the driver's seatbelt insertion state signal is the correct insertion state.

[0079] S3.3, judging according to the driver's seat automatic adjustment switch signal, when the driver's seat automatic adjustment switch signal is on, generating the front-rear and height-adjustment instructions of the driver's seat according to the body features and seating posture of the front driver; otherwise, when the driver's seat automatic adjustment switch signal is off, stopping the driver's seat automatic adjustment function.

[0080] Specifically, the front driver monitoring system 101 can shoot the behavior video of the front driver, extract the body features such as height and leg length and the seating posture such as upper and lower limb posture and activity space of the driver in the video by analyzing the front video, and the multimedia host controller 201 pre-stores the optimal seat position corresponding to various body features and seating postures, so as to match the extracted body features and seating posture with the pre-stored body features and seating posture, determine the optimal seat position according to the matching result, and generate the front-rear and height-adjustment instructions of the driver's seat according to the current seat position and the optimal seat position, and automatically adjust the driver's seat accordingly.

[0081] In the step S5, the multimedia host controller generates the front-rear adjustment instructions of the passenger seat, including:

[0082] S5.1, obtaining the number of passengers, seating positions, body features, seating posture, and seating time of each passenger, and the passenger seatbelt insertion state signal.

[0083] S5.2, judging whether the passenger seatbelt insertion state signal and the seating time meet the second set condition, if yes, controlling the multimedia audio to perform voice broadcast, and detecting and generating the passenger seat automatic adjustment switch signal in real time. The second set condition is that the passenger seatbelt insertion state signal is 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 prompts the passengers to select the seat automatic adjustment function through voice broadcast, the seat automatic adjustment button is pressed within a set time (e.g., 30 seconds). At this time, the seat controller detects and generates a passenger seat automatic adjustment switch signal, which triggers the subsequent automatic adjustment of the front and rear positions of the seat. The seat controller includes a driver's seat controller and a passenger seat controller. The above adjustment is only applicable to the passenger seat controller, avoiding the safety risks caused by the driver's seat adjustment during driving.

[0085] As shown in Figure 3 , the multimedia center screen 202 can also integrate the on-off control of all seat automatic adjustment options in the vehicle. The automatic adjustment function of each seat can be turned on or off through the multimedia center screen to generate the seat automatic adjustment switch signal of the driver and the passengers. The priority of this control is higher than the control by the passengers through the seat adjustment button.

[0086] S5.3, according to the passenger seat automatic adjustment switch signal, when the passenger seat automatic adjustment switch signal is on, the front and rear adjustment instructions of the passenger seat position are generated according to the number of passengers, the seating position, and the body characteristics and seating posture of each passenger. Conversely, when the passenger seat automatic adjustment switch signal is off, the passenger seat automatic adjustment function is stopped.

[0087] Specifically, the passenger monitoring system 102 can capture the behavior video of all passengers in the vehicle. By analyzing the video, the number of passengers, the seating position, and the body characteristics and seating posture of each passenger in the video are extracted. Similarly, the multimedia host controller 201 pre-stores the optimal vehicle seat position corresponding to different passenger numbers, seating positions, and different body characteristics and seating postures of passengers in various situations. In this way, the optimal vehicle seat position can be determined by matching the extracted information. Then, according to the current vehicle seat position and the optimal vehicle seat position, the front and rear adjustment instructions of the vehicle seat position are generated and the corresponding seat is automatically adjusted.

[0088] For example, for a vehicle with three rows of seats, as shown in Figure 4 , the adjustment strategy for adjusting the vehicle seat to the best space is as follows: first, in the case where the driver's seat is occupied, the front and rear positions of the driver's seat are automatically adjusted according to the driver's seat adjustment instructions; then, the front and rear positions of the passenger seat are adjusted according to the passenger seat adjustment instructions. The adjustment process includes:

[0089] (1) When a passenger sits on the left side of the second row, the left seats of the second and third rows, except for the driver's seat, will automatically adjust backward; then, when a passenger sits on the right side of the second row, the right seats of the first row will automatically adjust forward, and the right seats of the second and third rows will automatically adjust backward.

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

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

[0092] As another implementation, the Occupant Monitoring System (OMS) can also identify and acquire the behavioral status of occupants in non-driving positions. When it is detected that a passenger in a non-driving position has entered a sleep state, the signal is transmitted to the multimedia host controller via CAN. The multimedia host controller generates adjustment commands to automatically adjust the passenger's seat backrest, leg rest, lumbar support, etc., so that the passenger has a more comfortable sitting posture.

[0093] The above methods ensure that drivers have adequate legroom based on their body size, preventing leg fatigue and numbness during long drives. Automatic seat height adjustment provides drivers with good visibility, allowing for better road observation and improved driving safety. Automatic seat adjustment also enhances human-machine interaction and improves work efficiency. Furthermore, the restriction on seat adjustment (except when in Park) further improves driving safety. When a passenger in a non-driving position is detected as preparing to sleep, the system automatically adjusts the backrest, leg rest, and lumbar support to provide a more comfortable seating position. This automatic seat adjustment further enhances human-machine interaction and improves work efficiency. Finally, when occupants are identified, the system automatically adjusts the fore-and-aft distance of all seats, providing a more comfortable seating space for every passenger. This effectively enhances human-machine interaction, improves work efficiency, and elevates the overall technological feel of the vehicle.
