DETAILED DESCRIPTION

[0017] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are some but not all of the embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present disclosure.

[0018] In addition, the term "and / or" herein is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the front and rear associated objects.

[0019] Figure 1 A flowchart of a vehicle-based head injury adjustment method 100 according to an embodiment of the present disclosure is shown. The method 100 can include: Step 110, obtaining an acceleration when a head collides with a specific part of a vehicle at a preset speed; The acceleration when the head collides with the specific part of the vehicle at the preset speed is a simulated acceleration, which can be input in software.

[0020] The specific part of the vehicle can include one or more, such as Figure 2 As shown, it can be an A area or a B area or a C area or a D area of a vehicle cover, and the acceleration can be an acceleration in three directions of x, y and z with the center of the head impact position as the center, i.e. the acceleration in x, y and z directions, wherein the x direction is the length direction of the vehicle head, the y direction is the transverse direction of the vehicle head, and the z direction is the vertical direction.

[0021] Of course, when calculating the head injury index, the accelerations in the three directions can be synthesized, and the synthesized acceleration can be used for calculation.

[0022] Step 120, calculating a head injury index of the head caused by the specific part of the vehicle when colliding according to the acceleration; the head injury index is a HIC value, Head Injury Criterion.

[0023] Step 130, determining whether the head injury index is within a target injury index range; Step 140, if the head injury index is not in the target injury index range (i.e. higher than the upper limit of the target injury index range), adjust the acceleration so that the head injury index is in the target injury index range.

[0024] When the acceleration of the head hitting the specific part of the vehicle at a preset speed is obtained, the head injury index caused by the specific part of the vehicle to the head when hitting can be calculated according to the acceleration, and then it is judged whether the head injury index is in the target injury index range. If the head injury index is not in the target injury index range, it means that the head injury index is too large, so the acceleration can be adjusted so that the head injury index is in the target injury index range. In this way, the maximum acceleration that can not cause substantial damage to the head can be determined, and then the structure of the vehicle can be improved according to the acceleration. In this way, the head injury index can be controlled to effectively protect the head of the pedestrian in the collision.

[0025] In some embodiments, the specific part of the vehicle includes a plurality of specific parts. Correspondingly, the target injury index range includes a plurality of injury index ranges, wherein each injury index range corresponds to each specific part one by one. The acceleration of the head hitting the specific part of the vehicle at a preset speed includes: The acceleration of the head hitting each specific part of the vehicle at a preset speed is obtained. If the head injury index is not in the target injury index range, the acceleration is adjusted so that the head injury index is in the target injury index range, including: If the head injury index is not in the target injury index range, the acceleration is adjusted so that the head injury index is in the target injury index range, including:

[0026] The acceleration is different when hitting different positions, the head injury index is different, and the target injury index range is also different. Therefore, the acceleration of the head hitting each specific part of the vehicle at a preset speed can be obtained, and then if the head injury index is not in the target injury index range, the acceleration is increased or decreased so that the head injury index is in the target injury index range. In this way, the acceleration of different specific parts is adjusted respectively, and the structure of different specific parts of the vehicle is adjusted respectively.

[0027] In some embodiments, the method further includes: When adjusting the acceleration, record the increase or decrease of the acceleration when the head injury index is in the target injury index range corresponding to each specific part. Based on the initial value of the acceleration and the magnitude of its increase or decrease, determine the final value of the acceleration that will bring the head injury index within the range of each injury index corresponding to each specific site. The final value of acceleration = the initial value of acceleration + the increase in acceleration, or, The final value of acceleration = the initial value of acceleration - the decrease in acceleration.

[0028] The specific parts are stored in correspondence with the final value of the acceleration.

[0029] By storing the corresponding values ​​of acceleration for each specific part, it is easy to adjust the vehicle's structural design based on the acceleration at that specific location. For example, the structure of the inner and outer panels of the vehicle's front hood can be changed. Specifically, the shape of the outer panel can be changed, and the strength of the inner panel can be changed. If the inner panel is too strong, a hole can be drilled; if it is too weak, a bracket can be added.

[0030] In some embodiments, obtaining the acceleration when the head impacts a specific part of the vehicle at a preset speed includes: Obtain the peak value of the acceleration when the head impacts a specific part of the vehicle at a preset speed; The peak value is the maximum value. Of course, there can be multiple peak values; in this case, the peak value may differ depending on the specific area of ​​the vehicle. For example, in an impact... Figure 2 In region D as shown, the first peak among multiple peaks is obtained, and the impact is as follows: Figure 2 For regions A, B, and C shown, the second peak among multiple peaks is obtained.

[0031] The step of calculating the head injury index of a specific part of the vehicle on the head during an impact, based on the acceleration, includes: Based on the peak value of the acceleration and the duration of the peak value of the acceleration, a head injury index is calculated for a specific part of the vehicle during an impact.

[0032] Head injury indicators Where a is the resultant acceleration (g) in the three directions; It is a time interval (ms) between the start and end of the impact, that is, the duration of the peak acceleration.

[0033] In some embodiments, when the peak value of the acceleration includes multiple values, the peak value of the acceleration is obtained according to the region to which the specific part of the vehicle belongs.

[0034] When there are multiple peak acceleration values, increasing or decreasing the magnitude of acceleration may require simultaneously adjusting multiple acceleration values ​​to reduce the head injury index and bring it within the target injury index range. For example: Simulated head impact Figure 2 After entering region A, the original HIC is 1067, and the current head protection performance score is 0.5. By increasing the first acceleration peak and decreasing the second acceleration peak, the HIC value can be adjusted to 988, and the current head protection performance score is 0.75, thus improving the pedestrian head protection score in region A.

[0035] In some embodiments, the target damage index range varies depending on the head shape.

[0036] For example, the target injury index range corresponding to the head shape of adults is different from that corresponding to the head shape of children.

[0037] In some embodiments, the method further includes: Calculate the current head protection performance score based on the head injury index; Different head injury indicators correspond to different head protection performance scores. Therefore, based on this correspondence, the current head protection performance score under the given head injury indicator can be calculated.

[0038] The current head protection performance score is inversely proportional to the head injury index; that is, the lower the head injury index, the higher the current head protection performance score.

[0039] Obtain multiple head protection performance score ranges; The target head protection performance score interval to which the current head protection performance score belongs is determined from the plurality of head protection performance score intervals; The target head protection performance score range is highlighted with different colors.

[0040] After determining the target head protection performance score range to which the current head protection performance score belongs from the multiple head protection performance score ranges, the target head protection performance score range can be highlighted with different colors to provide sufficient reminders for different head protection performance score ranges.

However, those skilled in the art should understand that this disclosure is not limited to the described order of actions, because according to this disclosure, some steps can be performed in other orders or simultaneously.
