Description

Technical Field

[0001] The invention relates to the field of cockpit design, and in particular to a method and system for controlling the eye position adjustment of a driver. Background Art

[0002] The driver's sitting posture plays a key role in the driving process. Whether on the road or in the sky, an incorrect sitting posture may have a serious impact on driving safety, affecting the driver's accuracy in manipulating the vehicle and affecting the ability to respond to emergency situations. For vehicle drivers, sitting too forward may result in the driver being unable to effectively see the instrument panel and the surrounding environment, while sitting too backward may reduce the accuracy of control over the pedals and steering wheel. For flight pilots, sitting too forward may cause the pilot to lose internal vision and have difficulty operating the central control console and side handles, while sitting too backward will result in poor accessibility to the switches in the hood and instrument area, and reduced force to operate the side stick.

[0003] Vehicle and aircraft manufacturers often use ergonomic principles to design cockpits and seats. The Design Eye Point (DEP) is a key concept in vehicle and aircraft cockpit design. The Design Eye Point is a reference point based on the position of the pilot's eyes when the pilot is in a relaxed state. This reference point is used to ensure that the pilot can clearly see the instruments and equipment used for navigation, control and monitoring in a normal posture and line of sight, while also having an adequate field of view when observing the external environment. In addition, the Design Eye Point ensures that the pilot can maintain an optimal viewing angle to provide effective visual reference during critical operations.

[0004] In addition, pilot fatigue from prolonged sitting has been a long-standing problem in the industry. In particular, in the aviation industry, in the event of extreme weather and delays, the pilot's working time on the aircraft may exceed the 14 hours stipulated in relevant regulations. Flight missions are repetitive and arduous, and pilots are generally stressed. Under the premise of meeting safety requirements, comfort and functionality are increasingly becoming key factors in the design of driver seats.

[0005] Therefore, there is an urgent need for a method that can provide a prepared seat position to make the driver's eye position at the eye position design point while providing comfort for the driver. Summary of the invention

[0025] The specific embodiments described below in conjunction with the accompanying drawings are intended as descriptions of various configurations and are not intended to represent the only configurations in which the concepts described herein may be practiced. This specific embodiment includes specific details to provide a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details.

[0026] Based on this teaching, it will be appreciated by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure, whether it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects described can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods practiced using other structures, functionality, or structures and functionality that are supplementary to or different from the various aspects of the present disclosure described.

[0027] Although specific aspects are described herein, numerous variations and permutations of these aspects fall within the scope of the present disclosure. Although some benefits and advantages of preferred aspects are mentioned, the scope of the present disclosure is not intended to be limited to specific benefits, uses or objectives. The specific embodiments and the accompanying drawings merely illustrate the present disclosure rather than limit the present disclosure, and the scope of the present disclosure is defined by the attached claims and their equivalent technical solutions.

[0028] The driver's sitting posture plays a key role in the driving process. For the driver, sitting too far forward or too far back may have a serious impact on driving safety. Vehicle and aircraft manufacturers usually use ergonomic principles to design cockpits and seats. The design eye point is a key concept in the cockpit design of vehicles and aircraft. The design eye point is a reference point set according to the position of the driver's eyes in a relaxed state. This reference point is used to ensure that the driver can clearly see the instruments and equipment used for navigation, control and monitoring in a normal posture and line of sight, while also having sufficient field of view when observing the external environment. In addition, the design eye point also ensures that the driver can maintain the best viewing angle to provide effective visual reference during critical operations.

[0029] Currently, three-ball eye positioners are used in the aviation field to help pilots accurately locate the designed eye position. As an example, Figure 1The design eye position (e.g., reference eye point) of each flight, navigation (e.g., navigation display (NAVIGATION DISPLAY, ND)) and power unit instrument (e.g., primary flight display (PFD)) in the aircraft cabin for the pilot to see clearly for use is shown. At present, the three-ball eye positioner can help the pilot adjust the seat to the best position so as to obtain the best field of view and operating efficiency during the flight. Assuming that after the pilot sits on the seat, the actual eye position of the pilot moves in a vertical plane as the seat is adjusted, and the range of movement is constrained by the adjustment range of the seat. The design eye position is the intersection of the extension line of the two reference balls of the three-ball eye positioner and the vertical plane. However, this two-point one-line positioning method may cause inaccurate positioning due to the non-standard sitting posture of the driver, thereby affecting the driver's field of view, control and display panel recognition efficiency during the flight. In addition, under the premise of meeting the requirements of safety strength, comfort and functionality are also becoming more and more key factors in the design of driver seats.

[0030] In order to solve one or more of the above technical problems, the present disclosure proposes a method and system for controlling the eye position adjustment of the driver. According to the system of the present disclosure, a body scanning unit can be used to perform a multi-dimensional scan of the pilot's body to obtain the pilot's body parameters and an eyeball monitoring unit can be used to monitor the eyeball position to obtain the pilot's eyeball position, and then the seat position is intelligently adjusted based on the eye position and body parameters to automatically align the eyeball position with the designed eye position. At the same time, the driver can fine-tune the seat position according to his or her own sitting habits to take into account the driver's personalized sitting posture. In addition, the system of the present disclosure can also determine whether the fine-tuned seat position exceeds the eye position safety range, and issue a warning if the fine-tuned seat position exceeds the eye position safety range to ensure driving safety. In addition, the system of the present disclosure can also associate the last adjusted seat position that meets the eye position safety range with a specific driver and store the driver's eye position, body parameters and fine-tuned seat position together in a database for subsequent calls.

[0031] For ease of description, the present disclosure is described below using an aircraft (e.g., airplane) as an example of a vehicle. Those skilled in the art will appreciate that the method and system for controlling the eye position adjustment of a driver according to the present disclosure can be applied to various types of vehicles without departing from the scope of the present disclosure. In the following description of the present disclosure, aircraft and airplane can be used interchangeably, and driver and pilot can also be used interchangeably. The present disclosure is further described below in conjunction with specific embodiments and accompanying drawings, but the protection scope of the present disclosure should not be limited thereto.

[0032] Figure 2FIG. 2 shows a block diagram of a system 200 for controlling eye position adjustment of a pilot according to an embodiment of the present disclosure. Figure 2 As shown, the system 200 for controlling the eye position adjustment of a pilot may include: a processor 205 , a body scanning unit 210 coupled to the processor 205 , an eyeball monitoring unit 215 coupled to the processor 205 , and a seat adjustment mechanism 220 coupled to the processor 205 .

[0033] In one embodiment, the body scanning unit 210 may be configured to scan the body parameters of the pilot and transmit the body parameters to the processor 205 . Figure 3 FIG. 2 shows an example of a body scanning unit 210 according to an embodiment of the present disclosure. Figure 3 As shown, the body scanning unit 210 may include a standing scanning unit and a sitting scanning unit. In some cases, the body parameters may include standing body parameters, sitting body parameters and posture assessment parameters. When the pilot performs security check before boarding the aircraft, the body scanning unit is used to complete the scanning of the standing and sitting postures. For example, the body scanning unit may be installed in the security inspection device before the crew board the aircraft, including but not limited to the security inspection door, security inspection scanner, etc. In some cases, the body scanning unit 210 may read various body parameters of the pilot, such as but not limited to head size, eyeball position, height, upper limb length, elbow height, full arm length, upper arm length, armpit point height, hip width, shoulder width, shoulder peak elbow distance, forearm plus hand function forward extension, calf plus foot height, arm knee distance, sitting eye height, sitting shoulder height, sitting elbow height, sitting depth, etc. As a preferred example, the body scanning unit 210 uses a camera combined with radio frequency and microwave technologies to identify and multi-dimensionally scan various body appearance parameters. After completing the scan, the body scanning unit 210 transmits the scanned body parameters to the processor 205 (and the database).

[0034] In one embodiment, the eye monitoring unit 215 may be configured to scan the eye position of the pilot and transmit the eye position to the processor 205. The eye monitoring unit 215 may be used to identify the eye position of the pilot in the current seat position. Figure 4 FIG. 2 shows a schematic diagram of the installation of the eye monitoring unit 215 according to an embodiment of the present disclosure. Figure 4As shown, the eye monitoring unit 215 can be installed on the sun visor plate directly in front of the pilot's seat. In some cases, the eye monitoring unit 215 can compare the current eye position with the designed eye position to determine whether the eye position meets the eye position safety range. For example, if the pilot adjusts the seat and causes it to deviate from the designed eye position, the eye monitoring unit 215 can flash a red light to prompt the pilot to adjust the sitting posture until the pilot's eyes are aligned with the designed eye position. The eye monitoring unit 215 can flash a green light and disappear after flashing for 5 seconds. In some alternative situations, the eye monitoring unit 215 can transmit the front eye position to the processor 205 for the processor 205 to compare with the designed eye position. As an example, the eye monitoring unit 215 can identify the pilot's eye position through a camera combined with technologies such as radio frequency and microwaves. As a preferred example, the eye monitoring unit 215 can identify the center point (X) of the pilot's two eye positions. A ,Y A ,Z A ) and the designed eye site (X B ,Y B ,Z B ) for comparison.

[0035] In one embodiment, the seat adjustment mechanism 220 may be configured to adjust the seat according to the seat adjustment instruction received from the processor 205. In one example, the seat adjustment instruction may include the seat position recommended by the processor 205 according to the eye position and body parameters of the pilot, and the seat adjustment mechanism 220 may be configured to adjust the seat according to the recommended seat position. In another example, the seat adjustment instruction may include the seat adjustment instruction converted from the manual adjustment instruction manually input by the pilot received from the processor 205, and the seat adjustment mechanism 220 may be configured to adjust the seat according to the seat adjustment instruction. Alternatively, the seat adjustment mechanism 220 may be configured to receive the manual adjustment instruction manually input by the pilot and adjust the seat according to the manual adjustment instruction. In an alternative example, the seat adjustment mechanism 220 may also be configured to transmit the manual adjustment instruction to the processor 205. In some cases, the seat adjustment mechanism 220 may be an actuator located in the seat to realize intelligent adjustment and manual adjustment of the seat. The seat adjustment mechanism 220 may include a plurality of electric drive devices and a position feedback sensor capable of sensing the position of the seat and feeding back the position signal to the processor 205 to ensure that the seat stops at the correct position. In some cases, the seat adjustment mechanism can adjust the seat fore-aft position, the height, depth and inclination of the seat surface, the inclination of the seat back, the arch and height of the lumbar support, the fore-aft position and height of the headrest, etc. In some preferred cases, the manual adjustment function is provided on both sides of the seat (e.g., the seat bowl). In one example, the manual adjustment function can be integrated into the seat adjustment mechanism 220 or the processor 205.

[0036] In one embodiment, the processor 205 may be configured to: recommend a seat position according to the pilot's eye position and body parameters, receive a correction amount for fine-tuning the seat position based on the recommended seat position by the pilot and fine-tune the seat position based on the correction amount, determine whether the eye position after fine-tuning the seat position exceeds the safe eye position range, and issue an eye position over-limit warning in response to determining that the eye position after fine-tuning the seat position by the pilot exceeds the safe eye position range. For example, the processor 205 may be configured to receive the correction amount of the seat position input by the pilot from the seat adjustment mechanism 220. Alternatively, the processor 205 may be configured to receive the correction amount of the seat position input by the pilot. In some cases, the correction amount may include, but is not limited to, one or more of the following: the adjustment amount of the fore-and-aft position of the seat, the adjustment amount of the height, depth or inclination of the seat surface, the adjustment amount of the inclination of the seat back, the adjustment amount of the arch or height of the lumbar support, or the adjustment amount of the fore-and-aft position and height of the headrest, etc. In one example, the safe eye position range may be customized. For example, the safe eye position range may vary with different aircraft models. In some cases, the safe eye position range may include: a spatial range with a radius less than 35 mm centered on the optimal eye position, such as but not limited to 30 mm, 25 mm, 20 mm, 15 mm or 10 mm. In some cases, determining whether the eye position after fine-tuning the seat position exceeds the safe eye position range may include: comparing the coordinates (x, y, z) of the eye position after fine-tuning the seat position with the coordinates (x min ~x max ,y min ~y max ,z min ~z max) for comparison; and in response to determining that the coordinates on any axis of the eye position exceed the safe eye position range, determining that the eye position of the pilot after fine-tuning the seat position exceeds the safe eye position range. In one example, the processor 205 may be further configured to: after issuing the eye position over-limit warning: reset the seat to the recommended seat position; re-receive the correction amount of the pilot to fine-tune the seat position based on the recommended seat position and fine-tune the seat position based on the correction amount; determine whether the eye position after fine-tuning the seat position exceeds the safe eye position range; and in response to determining that the eye position of the pilot after fine-tuning the seat position exceeds the safe eye position range, issue an eye position over-limit warning. In one example, the system 200 for controlling the eye position adjustment of the pilot may further include: a database (not shown in the drawings). Alternatively, the processor 205 may be further configured to: in response to determining that the eye position of the pilot after fine-tuning the seat position is within the safe eye position range, associate the fine-tuned seat position with the pilot and store the pilot's eye position, body parameters and the fine-tuned seat position together in the database for subsequent retrieval. In one example, the database may record the pilot, the pilot's body parameters, the recommended seat position, and the final seat position obtained after fine-tuning the eye position within the safe eye position range for each flight. In a preferred example, the processor 205 may be further configured to: obtain the pilot's vision parameters; and optimize the recommended seat position based on the pilot's vision parameters, eye position, body parameters and the fine-tuned seat position. Preferably, the database may further record the pilot's vision parameters and body parameters. As the pilot sample size in the database continues to increase, the system 200 for controlling the pilot's eye position adjustment may continuously optimize the seat position recommendation model based on various parameters to make the recommended seat position more accurate.

[0037] In addition, the system 200 for controlling the eye position adjustment of the pilot can also provide a relaxing massage service during the cruising stage and provide one-key removal and other functions in emergency situations. Generally speaking, airlines require that pilots must always be in a position where they can directly control the aircraft when flying, and only when one crew member maintains control of the aircraft can the other crew member perform other activities (that is, during the flight, there must always be a flight crew member operating / monitoring the aircraft). Therefore, under the premise of meeting flight safety, a massage service can be provided to a crew member during the cruising stage. In some cases, the system 200 for controlling the eye position adjustment of the pilot can optionally include a massage unit. For example, the massage unit can receive the pilot's body parameters scanned by the body scanning unit, automatically adjust the position of the massage module corresponding to the pilot's neck, shoulders, and waist, and adapt to the pilot's body curve to provide customized massage services. The pilot can also issue massage instructions during the cruising stage, including setting the strength, massage position, etc. For another example, when a pilot is disabled, the other pilot in the two-person pilot system can move the disabled pilot's seat out with one key, including laying the seat back flat and moving the seat out to the farthest rear from the dashboard.

[0038] Figure 5 A flow chart of a method 500 for controlling the eye position adjustment of a driver according to an embodiment of the present disclosure is shown. For example, the method for controlling the eye position adjustment of a driver may be performed by a system 200 for controlling the eye position adjustment of a driver. The method 500 for controlling the eye position adjustment of a driver may include the following steps.

[0039] In step 505 , the system 200 for controlling the eye position adjustment of the driver may scan the eye position of the driver.

[0040] In step 510, the system 200 for controlling the eye position adjustment of the driver may scan the driver's body parameters. In one example, the body parameters may include standing body parameters, sitting body parameters, and posture assessment parameters.

[0041] At step 515 , the system 200 for controlling the driver's eye position adjustment may recommend a seat position based on the driver's eye position and body parameters.

[0042] In step 520, the system 200 for controlling the driver's eye position adjustment may receive the driver's correction amount for fine-tuning the seat position based on the recommended seat position and fine-tune the seat position based on the correction amount. In one example, the correction amount may include, but is not limited to, one or more of the following: an adjustment amount of the fore-and-aft position of the seat, an adjustment amount of the height, depth or inclination of the seat surface, an adjustment amount of the inclination of the seat back, an adjustment amount of the arch or height of the lumbar support, or an adjustment amount of the fore-and-aft position and height of the headrest, etc.

[0043] In step 525, the system 200 for controlling the driver's eye position adjustment may determine whether the eye position after fine-tuning the seat position exceeds the safe eye position range. In one example, the safe eye position range may include: a spatial range with a radius less than 35 mm centered on the optimal eye position, such as but not limited to 30 mm, 25 mm, 20 mm, 15 mm, or 10 mm. In one example, determining whether the eye position after fine-tuning the seat position exceeds the safe eye position range includes: comparing the coordinates (x, y, z) of the eye position after fine-tuning the seat position with the coordinates (x, y, z) of the safe eye position range. min ~x max ,y min ~y max ,z min ~z max ) for comparison; and in response to determining that the coordinates on any axis of the eye position exceed the safe eye position range, determining that the eye position of the driver after fine-tuning the seat position exceeds the safe eye position range.

[0044] In step 530, the system 200 for controlling the driver's eye position adjustment may issue an eye position limit-out warning in response to determining that the driver's eye position after fine-tuning the seat position exceeds the safe eye position range. In one example, after issuing the eye position limit-out warning, the system 200 for controlling the driver's eye position adjustment may further reset the seat to the recommended seat position; and re-receive the correction amount of the driver's fine-tuning the seat position based on the recommended seat position.
