Technical Field

[0001] This invention relates to the technical field of sub-instrument control, and more particularly to a sub-instrument and its control system and method. Background Technology

[0002] The secondary dashboard is a functional and decorative box located between the driver's and front passenger's seats, fixed to the floor. To improve the convenience of storage in the secondary dashboard, it is currently controlled to move along the length of the vehicle via sliding rails. Due to the legroom limitations of third-row passengers, the movement of the secondary dashboard is usually set to slide back and forth between the first and second rows. Because of this limited movement, the secondary dashboard cannot reach or partially reaches the reachable and comfortable area of ​​the first and third rows, making it difficult for passengers to retrieve items.

[0003] Therefore, improving the accuracy of the movement control of the sub-instrument panel is a technical problem that urgently needs to be solved. Summary of the Invention

[0023] Secondly, embodiments of the present invention also provide a control method for a sub-instrument panel, the method comprising:

[0024] Receive movement commands for the secondary dashboard;

[0025] The target user's sitting posture image is obtained based on the movement command, where the target user is the user who is picking up or placing an object on the sub-dashboard.

[0026] Determine the target user's comfort zone data for retrieving or placing items based on the sitting posture image;

[0027] Based on comfort zone data, the secondary instrument panel is moved along the length of the vehicle to move the storage compartment of the secondary instrument panel to a first target position in the length direction.

[0028] In one optional embodiment, determining the target user's comfort zone data for retrieving or placing objects based on the sitting posture image includes:

[0029] Determine the target user's sitting height based on the sitting posture image;

[0042] The sub-dashboard control system of the present invention includes a camera terminal, a controller, and a first drive component. The camera terminal receives movement commands from the sub-dashboard and captures an image of the target user's sitting posture based on the movement commands, outputting the image to the controller. The controller determines comfort zone data for the target user to retrieve or place items based on the posture image. Based on the comfort zone data, the first drive component is enabled to drive the sub-dashboard to move along the length of the vehicle, moving the storage compartment of the sub-dashboard to a first target position in the length direction, facilitating the target user to retrieve or place items in the storage compartment in a comfortable posture. The control system no longer relies on traditional user controls to determine the target position of the sub-dashboard movement. By recognizing the target user's sitting posture image, the target position can be more closely matched to the user's posture when retrieving or placing items, thereby improving the accuracy of the sub-dashboard movement control and providing better comfort for the user when retrieving or placing items from the storage compartment of the sub-dashboard.

Detailed Implementation

[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the protection scope of the embodiments of the present invention.

[0051] This invention provides a control system for a secondary instrument panel, comprising a camera terminal, a controller, and a first drive component. Please refer to... Figure 1 , Figure 1 This is a schematic diagram of the sub-instrument panel, with the first drive component 1 located at the bottom of the sub-instrument panel.

[0052] The camera terminal receives movement commands from the passenger dashboard. These commands can be triggered by a button press by the target user (the user retrieving or placing an item on the dashboard); or they can be triggered by the target user's body language or voice control. Receiving a movement command indicates that the passenger dashboard needs to be moved. To ensure accuracy, the camera terminal captures and outputs an image of the target user's sitting posture based on the movement command. The camera terminal can be an in-vehicle camera, such as one mounted on the rearview mirror. Upon receiving the movement command, the in-vehicle camera identifies the target user who triggered the command, captures an image of the user when their posture is correct, and outputs the image to a preset controller.

[0053] The controller can be the vehicle's central control system or a separate controller that controls the movement of the secondary instrument panel; its ability to control the secondary instrument panel is sufficient and is not specifically limited. The controller's first input is connected to the output of the imaging terminal. The controller receives images of the user's sitting posture and determines the comfort zone data for retrieving or placing items based on these images. The comfort zone data represents the location of the storage compartment in the secondary instrument panel when the user is in a comfortable posture. This comfort zone data can be determined through simulation software and verification with real users. Please refer to [link to relevant documentation]. Figure 2 , Figure 2The region J shown is the comfort zone (or comfort envelope region) represented by the comfort zone data. It should be noted that when determining the comfort zone data, the target user's sitting height can be identified based on the sitting posture image. The target user's height data can be determined from the sitting posture height, and the corresponding comfort zone data can be determined from the height data. The controller outputs the comfort data to the first drive component.

[0054] The first drive assembly can be a telescopic mechanism composed of hydraulic cylinders or pneumatic cylinders; it can also be a linear drive mechanism composed of a first track 9, a screw, a drive motor, a position sensor, etc. The control end of the first drive assembly is connected to the first output end of the controller. When the first drive assembly is a telescopic mechanism, its control end is the control end of the solenoid valve; when the first drive assembly is a linear drive mechanism, its control end is the power supply end of the drive motor. The first drive assembly is used to drive the sub-instrument panel to move along the length of the vehicle, allowing it to move from the middle of the first row where the driver is located to the middle of the second row. After receiving comfort zone data, the first drive assembly drives the sub-instrument panel to move along the length of the vehicle, moving the storage box 12 of the sub-instrument panel to the first target position in the length direction. The first drive assembly can be configured with an independent drive controller, which outputs drive pulses to the drive motor based on the comfort zone data and the current position, or it can directly determine the first target position to be moved to based on the comfort zone data. The first target position can be the initial position of an item entering the comfort zone in the horizontal direction, or it can output a prompt message after entering the comfort zone, and the storage box 12 can be stopped at any position in the comfort zone along the length of the vehicle by the target user.

[0055] In practical applications, due to the user's sitting posture, the storage box is positioned relatively low relative to the user's arm level, forcing the user to hunch over to retrieve or place items. This posture also affects the ease of operation. Therefore, please continue reading... Figure 1 In one specific implementation, the control system further includes a height sensor 2 and a second drive component 3.

[0056] A height sensor 2 is installed inside the storage compartment 12. This height sensor can be an infrared altimeter or a height-measuring radar, capable of measuring the height of items inside the storage compartment 12. The output of the height sensor is connected to the second input of the controller. The height sensor measures the height of items inside the storage compartment 12 and outputs the result to the controller. The controller also updates the comfort zone data based on the item height. The updated comfort zone data must at least include the horizontal height of the comfort zone when retrieving items. A second drive assembly is installed inside the storage compartment 12. This second drive assembly can also be configured as a telescopic mechanism or a linear drive mechanism. A tray 11 for carrying items is mounted on the mechanism. When configured as a linear drive mechanism, a second rail 10 needs to be installed vertically in the storage compartment 12 to guide the tray 11 during vertical movement. The control end of the second drive assembly is connected to the second output of the controller. The second drive assembly receives the updated comfort zone data and drives the sub-dashboard to move along the vehicle's height direction, moving the storage compartment 12 of the sub-dashboard to a second target position in the height direction. Similarly, the second target location can be the initial position of the item when it enters the comfort zone in the vertical direction, or any position in the comfort zone determined by the target user.

[0057] It should be noted that when items are raised and lowered based on the second drive component, the height can also be monitored by a height sensor to prevent items in the storage box from getting stuck due to excessive height.

[0058] In practical applications, some vehicles have three rows of seats. To prevent the sub-dashboard from interfering with the legs of third-row passengers during movement, the sub-dashboard can only be moved to the middle of the second-row seats. When users retrieve or place items through the storage compartment, they may be limited by the sub-dashboard's travel distance along the vehicle's length, causing inconvenience. Based on this, in one specific embodiment, the control system also includes a third drive component 4.

[0059] The third drive component 4 is disposed within the storage box 12. This third drive component can be configured as a conveyor belt mechanism, with the conveyor belt covering the tray. Items are placed on the conveyor belt, and the movement of the items is achieved by a motor driving the conveyor belt to rotate. The control terminal of the third drive component is connected to the third output terminal of the controller. The third drive component is used to drive the items in the storage box to continue moving along the length of the vehicle when the first drive component has not moved the items in the storage box to the first target position, thereby moving the items in the storage box to the first target position. It can be understood that the current position of the item on the tray can be detected by a height sensor. After the first drive component reaches its travel or control endpoint during movement, the third drive component can be controlled to move the item closer to the target user based on the detected current position. Alternatively, the third drive component can be directly controlled to move the item based on user input.

[0060] In practical applications, the user's body posture when picking up an item is related to the item's weight. For example, when picking up a heavier item, it is necessary to get closer to the item. Based on this, in one specific implementation, the control system also includes a weighing sensor 5.

[0061] A load cell 5 is installed inside the storage compartment 12. The output of the load cell is connected to the third input of the controller. The load cell is used to weigh the items inside the storage compartment and output the weight data. The controller is also used to update the comfort zone data based on the weight data. Please continue reading. Figure 1 For applications where a tray 11 is installed inside the storage compartment, a weighing sensor can be installed at the bottom of the tray 11 to weigh the items on it and output the weight data to the controller. The controller updates the comfort zone data based on the weight data to bring the items closer to the target user when controlling the movement of items in the sub-dashboard or storage compartment. In other words, the movement control of the first and second drive components needs to be determined based on the weight data.

[0062] It should be noted that when the second drive component includes a drive motor, the weight data can also be determined based on the operating current of the drive motor. For example, a calibration experiment can be conducted based on items of different weights and operating currents to obtain the correspondence between item weight and operating current. When the drive motor is running, the item weight can be determined based on its current current in the correspondence.

[0063] In practical applications, if the storage box is designed as an open structure, dust accumulation inside the box will occur. Therefore, in one specific implementation, the system further includes a roller shutter 6, a roller shutter switch, and a fourth drive assembly 7.

[0064] The roller shutter 6 can be made of flexible plastic. An outer protective plate 8 is installed on the sub-dashboard to form an opening for retrieving or placing items. The roller shutter is positioned on the opening of the storage compartment. A roller shutter switch outputs the opening and closing signal of the roller shutter. The roller shutter switch can be located on the door or sub-dashboard, allowing the user to control the movement of the roller shutter. The fourth drive assembly 7 is located inside the storage compartment and can be configured as a drive motor and multiple pulleys. One end of the roller shutter is fixedly connected to the output shaft of the drive motor. The roller shutter is laid on the opening of the compartment via multiple pulleys. The control terminal of the fourth drive assembly is connected to the output terminal of the roller shutter switch. The fourth drive assembly is used to drive the roller shutter to open or close the opening of the compartment. The movement of the roller shutter is achieved by the forward and reverse rotation of the drive motor. It can be understood that by setting up a roller shutter, dust can be reduced from entering the storage compartment, protecting the items and accessories inside from dust; at the same time, it improves the privacy of the placed items.

[0065] Based on the same inventive concept as the sub-instrument panel control system, this embodiment of the invention also provides a sub-instrument panel control method, which can be applied to the control terminal of the control system to control the movement of the sub-instrument panel. The control terminal can be the vehicle central control unit or a controller that independently controls the sub-instrument panel. Please refer to... Figure 3 , Figure 3 This is a flowchart of the control method. The control method specifically includes:

[0066] S11, Receive movement instructions for the sub-dashboard.

[0067] Specifically, the movement command can be triggered based on the target user's need to retrieve or place items, such as by triggering a preset switch on the car door to output the movement command; it can also be triggered based on body movements or voice control, and after the controller receives the movement command, it proceeds to step S12.

[0068] S12. Obtain the sitting posture image of the target user according to the movement command, wherein the target user is the user who picks up or places an object on the sub-dashboard.

[0069] Specifically, the sitting posture image can be obtained by taking a picture of the target user through a camera terminal set up in the vehicle. For example, the sitting position of the target user can be determined based on the movement command, and the image of the sitting position can be extracted from the captured image to obtain the sitting posture image. After obtaining the sitting posture image, proceed to step S13.

[0070] S13. Determine the comfort zone data for the target user to pick up or place items based on the sitting posture image.

[0071] Specifically, the sitting posture image can determine the target user's sitting height, thereby obtaining data such as the target user's height. People of different heights have corresponding comfort zones when picking up or placing objects, and corresponding comfort zone data can be defined based on these comfort zones. It can be understood that the data zone data can represent the location data of an area or the location data of a fixed position; there are no specific restrictions here, as long as it makes it more convenient for the target user to pick up or place objects.

[0072] For example, determining the comfort zone data for a target user to retrieve or place objects based on a sitting posture image includes:

[0073] The first step is to determine the target user's sitting height based on the sitting posture image. Please refer to [link / reference]. Figure 4-1 In the diagram, H1 represents the sitting height, which can be determined by the height of the target user's head in the sitting image. For example, a calibration experiment can be conducted between the head height of the sitting image and the sitting height to obtain the correspondence between the two. The sitting height can then be determined by using the head height of the current sitting image within this correspondence. After obtaining the sitting height, proceed to the next step.

[0074] The second step involves determining the comfort zone data based on the sitting posture height using a pre-defined data lookup table. This table establishes a correspondence between sitting posture height and comfort zone data. This table can be determined through simulation and actual verification experiments, allowing the corresponding comfort zone data to be identified based on the sitting posture height.

[0075] In practical applications, since the target users may have a wide range of heights, the heights of users selected based on experiments may not be universally applicable, potentially leading to inaccuracies in the data in the correspondence table. Therefore, in one specific implementation, before determining the comfort zone data based on sitting height in a preset data lookup table, the method further includes:

[0076] The first step is to obtain the sitting height of multiple users and the weight of multiple items in the storage compartment. The sitting height of multiple users can be selected based on actual needs. For example, based on the vehicle's usage scenario, the height of the covered users can be taken at preset intervals to obtain multiple sitting heights. Similarly, the weight of multiple items can be obtained by weighing various items that might be placed on the dashboard, based on the vehicle's usage scenario.

[0077] The second step involves obtaining an arm dataset for each sitting height based on multiple sitting posture heights and limb proportions. This arm dataset includes at least forearm length, upper arm length, shoulder joint angle, and elbow joint angle. Limb proportions characterize the relationship between human sitting height and arm dimensions, and can be represented by proportion coefficients that characterize the relationship between each sitting height and forearm length, upper arm length, shoulder joint angle, and elbow joint angle. Please refer to [link to relevant documentation]. Figure 4-1 and 4-2 The shoulder joint angle is the angle between the front-to-back direction of the body and the upper arm, denoted as C; the elbow joint angle is the angle between the forearm and the upper arm, denoted as D. Human height H can be calculated based on body proportions: H = H1 / 0.533.

[0078] Upper arm length L1 = 0.244H = 0.457H1; Forearm length L2 = 0.217H = 0.407H1.

[0079] If H≥170, shoulder point positioning: shoulder point positioning according to X=0.089H=0.167H1; Y=0.111H=0.208H1; Z=0.345H=0.657H1.

[0080] If H < 170, the shoulder point is located as follows: X = 0.067H = 0.124H1; Y = 0.1065H = 0.2H1; Z = 0.345H = 0.657H1.

[0081] X, Y, and Z are lengths calculated based on shoulder point positions. The shoulder joint angle and elbow joint angle are calculated using trigonometric functions to form multiple arm datasets. After obtaining the arm dataset for each sitting height, proceed to the next step.

[0082] The third step involves inputting multiple arm datasets and multiple item weights into a preset comfort rating equation to obtain multiple corresponding rating results. The comfort rating equation can be derived by quantitatively fitting a rating based on comfort. For example, multiple weight coefficients can be set, with each data point in the arm dataset and each item weight corresponding to a weight coefficient, to calculate multiple corresponding rating results. The rating results characterize the comfort level of the user when picking up or placing items.

[0083] For example, multiple arm datasets and multiple item weights are input into a preset comfort rating equation to obtain multiple corresponding rating results, including:

[0084] The first scoring result f(A,C,M) is obtained according to the formula f(A,C,M)=13.9-λ1×A-λ2×C-λ3×M, where A is the upper arm length, C is the shoulder joint angle, M is the weight of the item, λ1 is the first preset coefficient, λ2 is the second preset coefficient, and λ3 is the third preset coefficient. λ1, λ2, and λ3 can be freely set according to actual needs. For example, if λ1 is selected within the preset range of 0.005-0.08, it can be set to 0.006; if λ2 is selected within the preset range of 0.02-0.025, it can be set to 0.022; and if λ3 is selected within the preset range of 0.6-0.7, it can be set to 0.656.

[0085] According to the formula f(B,D,M)=λ4×B-λ5×D-λ6×M-3.4, the second scoring result f(B,D,M) is obtained, where B is the forearm length, D is the elbow joint angle, λ4 is the fourth preset coefficient, λ5 is the fifth preset coefficient, and λ6 is the sixth preset coefficient. Similarly, λ4, λ5, and λ6 can be freely set according to actual needs. For example, if λ4 is selected within the preset range of 0.03-0.04, it can be set to 0.035; if λ5 is selected within the preset range of 0.015-0.02, it can be set to 0.018; and if λ6 is selected within the preset range of 0.6-0.7, it can be set to 0.666.

[0086] It should be noted that, to reduce redundancy in data calculation, preset intervals can be set for upper arm length A, forearm length B, shoulder joint angle C, and elbow joint angle D. For example, 30≤A≤155, 110≤B≤155, 30≤C≤130, and 85≤D≤155 can be set. Based on the above method, the comfort score corresponding to the arm dataset and the weight of the item can be calculated. After obtaining the score, proceed to the next step.

[0087] The fourth step is to define the storage compartment location data corresponding to scores below the scoring threshold as comfort zone data. Comfort scoring standards can be set; for example, a score of 0-2 indicates very comfortable, 3-4 indicates moderately comfortable, 4-6 indicates uncomfortable but within an acceptable range, and 6-8 indicates very uncomfortable and unacceptable. The scoring threshold can be set to 4; scores below the threshold indicate good operational comfort, and the corresponding storage compartment location data is defined as comfort zone data.

[0088] Step 5: Generate a data lookup table based on the data for each comfort zone and the sitting height for each comfort zone. There is a correspondence between the comfort zone data and the sitting height, so they can be mapped one-to-one to generate a data lookup table. The comfort zone data for the target user to retrieve or place objects is determined using the sitting posture image and the data lookup table. After obtaining the comfort zone data, proceed to step S14.

[0089] S14. Drive the sub-instrument panel along the length of the vehicle based on the comfort zone data to move the storage box of the sub-instrument panel to the first target position in the length direction.

[0090] Specifically, based on comfort zone data, drive commands are output to the first drive component, causing the sub-instrument panel to move along the length of the vehicle. The sub-instrument panel gradually approaches the target user, and once it reaches the position corresponding to the comfort zone data, the first target position can be determined. Alternatively, after entering the area corresponding to the comfort zone data, the instrument panel can stop at the first target position based on the target user's control.

[0091] Based on the same inventive concept as the sub-instrument control system, embodiments of the present invention also provide a sub-instrument, which includes any of the control systems.

[0092] The technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0093] The secondary instrument panel control system includes a camera terminal, a controller, and a first drive assembly. The camera terminal receives movement commands from the secondary instrument panel, captures images of the target user's seating posture based on these commands, and outputs the images to the controller. The controller determines comfort zone data for the target user to retrieve or place items based on the posture images. Based on this comfort zone data, the first drive assembly is enabled to move the secondary instrument panel along the length of the vehicle, moving the storage compartment to a first target position along the length, allowing the target user to retrieve or place items comfortably. The control system no longer relies on traditional user input to control the target position of the secondary instrument panel. By recognizing the target user's seating posture, the target position can be more closely matched to the user's posture when retrieving or placing items, thus improving the accuracy of the secondary instrument panel movement control and providing greater comfort for the user when retrieving or placing items from the storage compartment.

Furthermore, the present invention can take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, etc.) containing computer-usable program code.
