[0023] First, the application scenario of this application is explained. The technical solution of this application is applicable to the layout design of the vehicle's central control screen. There are two main forms of vehicle central control screens. One is an independent type, that is, the central control, instrument and other devices each have their own independent screens. The other is a through-type, that is, the instrument cluster, central control, co-pilot screen, etc. share a screen that runs through the entire dashboard. This application is mainly applicable to independent central control screens.

[0024] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0025] Figure 1 This is a flow chart of a method for determining the position of a vehicle central control screen provided in an embodiment of the present application. Figure 1As shown, an embodiment of the present application provides a method for determining the position of a vehicle central control screen, including:

[0026] S1. Determine a plurality of driver human body models of different heights.

[0027] During the initial development phase, the driver mannequin parameters must be confirmed. Based on the human body layout specifications, the front seat reference point (SgRP) is determined. Using Ramsis, human models with height coverage of 5%, 50%, and 95% are created, respectively, according to the domestic adult human dimensions specified in GB / T 10000-2023. These serve as different driver mannequins. The driver mannequin includes dimensional parameters such as height, arm length, leg length, and shoulder width. The SgRP, a key indicator of seat position and typically the center point of the seat, ensures accurate distances and angles between the driver mannequin and vehicle components.

[0028] S2. For each driver human body model, based on the driver human body model, determine the corresponding vehicle central control screen position set according to preset verification rules.

[0029] Here, for three different driver body models with height coverage of 5%, 50% and 95%, the first vehicle central control screen position set, the second vehicle central control screen position set and the third vehicle central control screen position set can be determined respectively.

[0030] The preset verification rules here include verification of multiple aspects such as hand reach, field of view and reflection verification.

[0031] S3. Determine a final position set of the vehicle central control screen based on the vehicle central control screen position sets corresponding to all driver human body models.

[0032] In step S3, the final position set of the vehicle central control screen can be determined based on the intersection of the first vehicle central control screen position set, the second vehicle central control screen position set, and the third vehicle central control screen position set. The position set here can be an area box or discrete coordinate points.

[0033] In this way, by using the human body model to confirm the hand-reach space, field of view and reflection verification, the position of the central control screen is optimized, making the position of the central control screen in the vehicle more reasonable, suitable for a wide range of people, and improving the comfort and convenience of the driver in using the central control screen.

[0034] In a specific embodiment of the present application, for each driver human body model, the vehicle central control screen position set corresponding to the driver human body model is determined by the following method:

[0035] First, determine the vehicle's central control screen and its surrounding components. Define the size of the central control screen, as well as the size and location of the surrounding components. The central control screen can be either horizontally or vertically oriented, and can be 10.1 inches or 12.3 inches. Surrounding components can include the instrument panel, air vents, or other physical buttons.

[0036] The driver's human body model is adjusted to a driving posture and the seat angle parameters are adjusted. Specifically, the established human body model point H is constrained to the seat point R, the model posture is adjusted to a sitting posture suitable for driving, and the seat back angle A40-1 parameter is determined.

[0037] Based on the human body model, extract the central eye point, seat parameters, center console dimensions, and surrounding components to confirm layout requirements. When describing layout requirements, the center console must not interfere with other components and must meet minimum clearance requirements. The center of the center console must align with Y0.

[0038] Figure 2 This is a flow chart of the steps for determining the position set of a vehicle central control screen provided in an embodiment of the present application. Figure 2 As shown, for each driver human body model, the corresponding vehicle central control screen position set can be verified through the following steps:

[0039] S20: Determine a first position set of the vehicle central control screen based on the hand reach of the driver's human body model.

[0040] When checking the reach range, it is necessary to confirm that the reach range of each human body model can cover more than 95% of the entire central control screen. Specifically, based on the reach range of the driver human body model, the steps of determining the first position set of the vehicle central control screen include:

[0041] The maximum and minimum hand reach interfaces corresponding to the driver human body model are determined. The overlapping interface between the maximum and minimum hand reach interfaces is determined. The layout positions of the vehicle's central control screen are updated to identify all layout positions where the overlapping interface covers an area greater than a first preset percentage of the vehicle's central control screen, and these positions are defined as a first position set. The first preset percentage is 95%.

[0042] S21. Determine a second position set of the vehicle central control screen based on the visual range of the driver human body model and the first position set of the vehicle central control screen.

[0043] When verifying the visual range, the steering wheel's occlusion of the central control screen is limited to the lower left corner of the central control screen, the screen cannot be disconnected, and the occlusion cannot exceed 5% of the entire screen. Based on the visual range of the driver's human body model and the first position set of the vehicle's central control screen, the steps of determining the second position set of the vehicle's central control screen include:

[0044] The layout positions of the vehicle central control screen are updated based on the first position set to determine all layout positions that satisfy the requirement that the steering wheel blocks the vehicle central control screen by less than a second preset ratio, and determine them as the second position set. The second preset ratio is 5%.

[0045] S22. Based on the screen reflection range of the driver human body model and the second position set of the vehicle central control screen, determine a third position set of the vehicle central control screen as the vehicle central control screen position set corresponding to the driver human body model.

[0046] When checking the reflection analysis, requirements should be made for the height and angle of the central control screen so that the reflection area formed by the light entering from each windshield accounts for less than or equal to 2% of the entire screen. Based on the screen reflection range of the driver human body model and the second position set of the vehicle central control screen, the steps of determining the third position set of the vehicle central control screen include:

[0047] The layout positions of the vehicle central control screen are updated based on the second position set to determine all layout positions where the area of ​​the reflective area corresponding to the target window covering the area of ​​the vehicle central control screen is less than a third preset ratio, as a third position set. The third preset ratio is 2%.

[0048] For the preliminarily arranged central control screen, in addition to meeting the basic layout requirements, reach range, and visual range, after reflection analysis, it should be ensured that the right side tilt angle of the central control screen also meets the comfort requirements as much as possible to facilitate the co-pilot to view and operate. After the evaluators verify the physical model, the feasibility of the layout plan is confirmed. After the preliminary layout data of the central control screen passes the above verification, the third position set can be determined as the corresponding first vehicle central control screen position set.
