[0002] With the development of the automotive industry, vehicle comfort has become one of the main factors influencing consumers' car purchase decisions. Ergonomics is an indispensable part of vehicle comfort design. In existing technologies, the design of hood comfort typically involves data-driven design of the hood's dimensions and opening angle during the vehicle design phase. However, this approach lacks verification devices, making it impossible to determine the comfort of hood operation in a real vehicle. Furthermore, unreasonable hood opening height and angle can cause inconvenience for subsequent vehicle maintenance and inspection.

[0005] Optionally, the opening parameters of the hood can be adjusted based on the positional relationship between the calibration area and the comfort zone of the hood, including: If part of the calibration zone is higher than comfort zone 2, or if part of the calibration zone is lower than comfort zone 3, then the position of the hinges and / or the opening angle of the hood should be adjusted.

[0006] Optionally, if the calibration area of ​​the hood is partially higher than the comfort zone 2, the position of the hinges and / or the opening angle of the hood shall be adjusted, including: Adjust the hinge position toward the front bumper and / or reduce the opening angle of the hood.

[0007] Optionally, if a portion of the hood's calibration zone is lower than the comfort zone 3, the hinge position and / or the hood's opening angle may be adjusted, including: Adjust the hinge position toward the windshield and / or increase the opening angle of the hood.

[0008] Optionally, the method also includes: If the entire calibration area is not within the comfort zone 1, a comfort evaluation is performed on the positional relationship between the calibration area and the comfort zone of the hood to obtain the evaluation result. Based on the evaluation results, the opening parameters of the hood were adjusted.

[0009] Optionally, based on the evaluation results, the position of the hinges and / or the opening angle of the hood may be adjusted, including: If the evaluation result is satisfactory, the position of the hinge and the opening angle of the hood remain unchanged. If the evaluation result is unsatisfactory, the position of the hinge and / or the opening angle of the hood will be adjusted.

[0010] Optionally, the inspection area of ​​the hood includes the front end area of ​​the hood and the latches located on the front end area of ​​the hood.

[0012] According to a third aspect of the invention, a vehicle is provided, the vehicle including a vehicle body and a hood mounted on the vehicle body, wherein the aforementioned hood comfort determination method is applied when determining the position of the hood on the vehicle.

[0013] The above-described one or more technical solutions in the embodiments of this specification have at least the following technical effects: This specification provides a method and apparatus for determining hood comfort. The method involves defining a comfort zone for the hood; after opening the hood, determining the positional relationship between a verification zone at the hood's front end and the comfort zone; and then adjusting the hood's opening parameters based on this positional relationship.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] This invention provides a method for determining the comfort of a machine hood, combined with... Figure 1 The flowchart shown illustrates that the method for determining the comfort of the hood includes steps 101 to 103: Step 101: Define the comfort zone of the hood; In this embodiment, the method for determining hood comfort is applicable to the vehicle design and development stage. After the design data for the hood is determined, a comfort model test can be conducted on a test bench to determine whether the position of the hood after opening meets the comfort requirements. To define comfort, this embodiment will define the comfort zone of the hood in conjunction with the vehicle model to be developed.

[0024] It should be explained that the comfort zone of the engine cover is determined based on statistical experiments conducted on a large number of people of different heights for the vehicle model to be developed.

[0025] Combination Figure 2 As shown, the comfort zone comprises three parts, namely Comfort Zone 1, Comfort Zone 2, and Comfort Zone 3, arranged vertically, corresponding to Zones 1, 2, and 3 in the diagram, respectively. Comfort Zone 1 is located between Comfort Zones 2 and 3, in a central position. It is easy to understand that Comfort Zone 1 is the optimal area. Comfort Zone 2 is adjacent to and above Comfort Zone 1, while Comfort Zone 3 is adjacent to and below Comfort Zone 1. Comfort Zones 2 and 3 are considered acceptable recommended areas. It should be noted that different vehicle models, due to differences in body shape, size, etc., may have different comfort zones applicable; this embodiment does not impose limitations on this.

[0026] Step 102: After opening the machine cover, determine the positional relationship between the calibration area at the head end of the machine cover and the comfort area of ​​the machine cover; In this embodiment, after the relevant design data of the hood is determined, a comfort model verification will be performed. During verification, the hood will be opened, and once it opens at the designed angle, its position will be determined. In this embodiment, the area at the front end of the hood is designated as the verification area for comfort verification. The verification area is small, consisting only of the area near the front of the vehicle. The verification area includes the front end of the hood and a latch installed on the front end. The latch is located below the front end of the hood and is fixedly connected to it. The latch is the component that ensures the connection between the hood and the vehicle body when the hood is closed. The latch is located inside the hood compartment. The length of the latch needs to be determined based on the position of the latch. The length of the latch varies depending on the position of the latch.

[0027] When determining the positional relationship between the calibration zone and the comfort zone, it is necessary to first determine the placement of the comfort zone. (Combined with...) Figure 3 As shown, this embodiment creates a vertical cross-section of the vehicle based on the midpoints of the front bumper and rear. A coordinate system is then established within this cross-section, with the horizontal ground line as the X-axis and the perpendicular line from the midpoint of the front bumper to the ground line as the Y-axis. The comfort zone is placed within this cross-section, with the distance between the leftmost edge of the comfort zone and the Y-axis being a preset distance, for example, 200mm. The height of the highest point of the comfort zone from the ground line is fixed, and this height value can be determined based on the height of the target customer group.

[0028] Once the comfort zone is determined, the next step is to determine its positional relationship with the calibration zone. This relationship primarily refers to whether the calibration zone is located within the comfort zone. For example, the calibration zone may be entirely within the comfort zone, or partially higher or lower.

[0029] Step 103: Adjust the opening parameters of the machine cover according to the positional relationship between the calibration area and the comfort zone of the machine cover.

[0030] After determining the positional relationship between the calibration area and the comfort zone of the hood, the opening parameters of the hood can be adjusted based on this relationship. It's important to note that the opening parameters determine the position of the calibration area after the hood is opened. By changing the opening parameters, the position of the calibration area after the hood is opened can be altered. These opening parameters include the position of the hinges and the opening angle of the hood. In other words, the position of the hood on the vehicle primarily depends on the opening angle and the position of the hinges.

[0031] The hinge is the component that connects the hood to the body. The hinge is usually installed on the end of the hood near the windshield.

[0032] It's easy to understand that, all other things being equal, the larger the opening angle of the hood, the higher the calibration zone after the hood is opened; the smaller the opening angle of the hood, the lower the calibration zone after the hood is opened. In actual vehicles, different opening angles can be achieved by adjusting the length of the support rods inside the hood compartment. Alternatively, some vehicles have an automatic hood opening mechanism, where the hood automatically opens to a preset opening angle when opened.

[0033] Additionally, the closer the hinge is to the front bumper, the shorter the hood's length in the X-axis direction; conversely, the closer the hinge is to the windshield, the longer the hood's length in the X-axis direction.

[0034] In this embodiment, to ensure the comfort of operating the machine cover, the positional relationship between the calibration area and the comfort area must meet certain requirements after the cover is opened. If this requirement is met, it indicates that the machine cover design is reasonable; otherwise, it is necessary to discuss the specific circumstances to determine whether the opening parameters of the machine cover need to be adjusted.

[0035] In one optional implementation, referring to the foregoing, the comfort zone is divided into Comfort Zone 1, Comfort Zone 2, and Comfort Zone 3. The positional relationships between the verification zone and Comfort Zones 1, 2, and 3 include the following: The entire verification area is located in Comfort Zone 1; The calibration zone is partially higher than the comfort zone 2; The calibration zone is partially lower than the comfort zone 3; The calibration area was not entirely in comfort zone 1, and some areas were located in comfort zone 2 and / or comfort zone 3.

[0036] Based on the above situations, there are different adjustment strategies for the opening parameters of the hood.

[0037] Specifically, if part of the calibration zone is higher than comfort zone 2, or if part of the calibration zone is lower than comfort zone 3, the position of the hinge and / or the opening angle of the hood shall be adjusted.

[0038] It should be noted that the optimal recommended area for the calibration zone is Comfort Zone 1. A calibration zone in Comfort Zone 2 or Comfort Zone 3 is also acceptable, but whether the opening parameters need adjustment depends on the specific circumstances. However, if the calibration zone exceeds the Comfort Zone, it indicates that the hood's comfort level is insufficient. For example, if the calibration zone is positioned too high, causing part of it to be above or even completely above Comfort Zone 2; or if the calibration zone is positioned too low, causing part of it to be below or even completely below Comfort Zone 3. In this case, the hood's opening parameters must be adjusted, that is, the position of the hinges and / or the opening angle of the hood must be adjusted to bring the calibration zone closer to Comfort Zone 1.

[0039] When making adjustments, if the calibration area of ​​the hood is partially higher than the comfort zone 2, the position of the hinges can be adjusted towards the front bumper, and / or the opening angle of the hood can be reduced.

[0040] For areas where the hood's calibration zone is lower than the comfort zone 3, the hinge position can be adjusted towards the windshield, and / or the hood's opening angle can be increased.

[0041] In terms of hinge position design, if the hinge is located closer to the front bumper, the length of the hinge in the X-axis direction will be shorter, and for the same opening angle, the height of the front hood area will be lower; if the hinge is located closer to the windshield, the length of the hinge in the X-axis direction will be longer, and for the same opening angle, the height of the front hood area will be higher.

[0042] With the hinge position fixed, increasing the opening angle will raise the height of the front section of the hood; decreasing the opening angle will lower the height of the front section of the hood. Based on this principle and in accordance with actual needs, one of the hinge position and the opening angle can be adjusted individually, or both can be adjusted simultaneously.

[0043] Therefore, if the calibration zone is partially higher than the comfort zone, it indicates that the calibration zone needs to be lowered. Based on the above, this can be achieved by adjusting the hinge position towards the front bumper individually, or by reducing the hood opening angle. Alternatively, the hinge position can be adjusted towards the front bumper while simultaneously reducing the hood opening angle.

[0044] Considering that the front area of ​​the hood is curved rather than flat, and similarly, the comfort zone is also defined by curves, in actual design, if the calibration zone is significantly higher than the second comfort zone, or even completely higher, it is generally considered to adjust both the hinge position and the opening angle simultaneously.

[0045] Similarly, if the calibration zone is partially lower than the comfort zone, it indicates that the calibration zone needs to be raised. Based on the above, you can either adjust the hinge position towards the windshield individually, or increase the hood opening angle, or adjust the hinge position towards the windshield while simultaneously increasing the hood opening angle.

[0046] Considering that the front area of ​​the hood is curved rather than flat, the comfort zone is also defined by a curve. Therefore, in actual design, if the calibration zone is significantly lower than the third comfort zone, or even completely lower, it is generally considered to adjust both the hinge position and the opening angle simultaneously.

[0047] In this embodiment, there is another case: if the calibration area is not entirely within the comfort zone, a comfort evaluation is performed on the positional relationship between the calibration area and the comfort zone of the machine cover to obtain the evaluation result. Based on the evaluation results, the position of the hinges and / or the opening angle of the hood will be adjusted.

[0048] It should be noted that Comfort Zone 2 and Comfort Zone 3 are acceptable areas. This means the entire calibration area is within the Comfort Zone, but not entirely within Comfort Zone 1; some areas are in Comfort Zone 2 and / or Comfort Zone 3. For example, the latch might be long, with the front of the hood in Comfort Zone 1 and the latch in Comfort Zone 2; or the front of the hood might be in Comfort Zone 3 and the latch in Comfort Zone 1, etc.

[0049] In situations like the above, a location evaluation is necessary. Location evaluation involves a predetermined number of evaluators assessing the comfort of the enclosure. If the proportion of evaluators who find the enclosure comfortable is greater than a predetermined proportion, the evaluation result is considered satisfactory; conversely, if the proportion is less than or equal to a predetermined proportion, the evaluation result is considered unsatisfactory.

[0050] For example, if the front section of the hood is in comfort zone one and the latch is in comfort zone two, then 200 evaluators of different heights (between 1.5 meters and 1.9 meters) are invited to evaluate the comfort of the hood after it is opened. If 170 of them believe that the hood meets the comfort requirements (e.g., the opening height is appropriate, it does not bump the head, and it is convenient for maintenance operations), then the proportion of people who believe that the hood meets the comfort requirements is 85%, which is greater than the preset proportion of 75%. Therefore, the evaluation result of the comfort of the hood is satisfactory.

[0051] For example, if the front section of the hood is located in comfort zone three and the latch is located in comfort zone one, then 300 evaluators of different heights (between 1.5 meters and 1.9 meters) are invited to evaluate the comfort of the hood after it is opened. If 180 people believe that the hood meets the comfort requirements (e.g., the opening height is appropriate, it does not bump the head, and it is convenient for maintenance operations), then the proportion of people who believe that the hood meets the comfort requirements is 60%, which is less than or equal to the preset proportion of 75%. Therefore, the evaluation result of the comfort of the hood is unsatisfactory.

[0052] Once the evaluation results are obtained, the position of the hinge and / or the opening angle of the hood can be adjusted accordingly. If the evaluation result is satisfactory, the position of the hinge and the opening angle of the hood remain unchanged; if the evaluation result is unsatisfactory, the position of the hinge and / or the opening angle of the hood are adjusted. Specific adjustment methods can be found in the preceding content and will not be repeated here.

[0053] In summary, the method for determining the position of a hood provided in this specification involves defining a comfort zone for the hood; after opening the hood, determining the positional relationship between the verification zone at the front end of the hood and the comfort zone; and then adjusting the opening parameters of the hood based on the positional relationship between the verification zone and the comfort zone. Thus, by defining the comfort zone, the ease of operation of the hood position can be determined during the early design phase. This improves the design efficiency of the hood, enhances comfort, and saves on vehicle development cycle and costs.

[0057] In one alternative implementation, the adjustment module is further configured to: If part of the calibration zone is higher than comfort zone 2, or if part of the calibration zone is lower than comfort zone 3, then the position of the hinges and / or the opening angle of the hood should be adjusted.

[0061] In one alternative implementation, the adjustment module is further configured to: If the evaluation result is satisfactory, the position of the hinge and the opening angle of the hood remain unchanged; If the evaluation result is unsatisfactory, the position of the hinge and / or the opening angle of the hood will be adjusted.

[0062] In summary, the hood position determination device provided in this specification defines a comfort zone for the hood; after opening the hood, it determines the positional relationship between the verification zone at the hood's front end and the comfort zone; then, based on the positional relationship between the verification zone and the comfort zone, it adjusts the hood's opening parameters.
