[0039] L: X-direction distance between the driver's point H and the center point of the central control screen;

[0040] W: Y-direction distance between the driver's point H and the center point of the central control screen;

[0041] H: Z-direction distance between the driver's H point and the center point of the central control screen;

[0042] A: The angle between the central control screen and the XY plane.

[0043] S: Operational convenience evaluation model.

[0044] One or more embodiments of the present invention provide a method for evaluating the convenience of operating a central control screen of an automobile. For a given vehicle model, the method can evaluate the convenience of operating the central control screen for the driver based on the central control screen position design parameters. Furthermore, during the vehicle interior design stage, the setting position of the central control screen can be optimized, and a universal design solution suitable for most drivers can be provided for the vehicle model. Figure 1 As shown, the method comprises the following steps:

[0045] Step 101: Obtain the posture parameters of the central control screen of the vehicle to be tested and the adjustable range of the driver's seat posture;

[0046] Step 102: Determine at least two boundary states of the driver's seat according to the adjustable interval boundary;

[0047] Step 103: Under each boundary state, calculate the distance between point H and the center point of the central control screen in the X direction, Y direction and Z direction;

[0048] Step 104: Evaluate the operational convenience under each boundary state according to the operational convenience evaluation model;

[0049] Step 105: When the operational convenience in each boundary state meets the requirements, it is considered that the central control screen meets the operational convenience requirements.

[0050] The above method simplifies the central control screen calibration process by constructing an operational convenience evaluation model, and can transform repeated manual tests into model-based automatic tests. At the same time, by testing the operational convenience of the driver's seat under boundary conditions (for example, when the driver's seat is furthest forward and up, and when the driver's seat is furthest down and back), the central control screen is considered to meet the operational convenience requirements when the operational convenience requirements are met under all boundary conditions.

[0051] The above method can be used to effectively evaluate the operational convenience of the vehicle's central control screen during the design and development phase, improve the efficiency of engineers, effectively reduce the probability of problems occurring later, and save unnecessary waste for the project.

[0052] In step 101, the central control screen posture parameters include the position of the central control screen and its pitch angle. The driver's seat posture adjustable range includes the adjustable position range in four directions of the seat, and of course, it can also include the adjustable range of the seat back tilt angle.

[0053] In step 102, the at least two boundary states refer to at least two boundary states including when the driver's seat is at its most forward and upward position, and when the driver's seat is at its most downward and backward position. If the seatback is tilted, then at least two boundary states are included: when the driver's seat is at its most forward and upward position with the seatback vertical, and when the driver's seat is at its most downward and backward position with the seatback tilted to the maximum.

[0054] In step 103, the relative position relationship between the driver and the central control screen is the main factor affecting operability. Therefore, in some embodiments, the relative position relationship between the driver and the central control screen is used as a measure and quantified with point H as the reference point. The H point of a passenger car is a reference point that can accurately determine the seat position of the driver or passenger. It is the "span point" of the rotation point connecting the torso and the thigh. When the seat posture is determined, the current H point can be estimated. Figure 2 As shown, L, W and H represent the distances between point H and the center point of the central control screen in the X, Y and Z directions respectively.

[0055] In addition, the tilt angle of the central control screen will affect the driver's field of view of the central control screen, and thus indirectly affect the convenience of operation. Therefore, the angle between the central control screen and the horizontal plane can be further used as an influencing factor, such as Figure 2 As shown, A represents the angle between the central control screen and the horizontal plane.

[0056] In step 104, as a specific implementation, the operation convenience evaluation model S is obtained according to the multiplication relationship of L, W and H. The calculation formula can be:

[0057] S=(L×W×HL min ×W min ×H min ) / (L max ×W max ×H max -L min ×W min ×H min )

[0058] Among them, L min , W min , H min are the minimum values ​​obtained from the test to meet the operability requirements, L max , W max , H max are the maximum values ​​obtained from the test that meet the operability requirements. Based on this, the value range of S is 0-1, and the convenience threshold is set, for example, it can be set to 0.6. When S>0.6, it is considered that the convenience requirement is not met.

[0059] As an example, by investigating the vehicles on the market, we obtained the L, W and H of drivers of different heights for different models and different seat positions, and their scores on operability, based on the convenience of the driver's fingers on the screen when operating the central control screen. By analyzing the contact convenience parameters of the interaction between drivers of different models and the central control screen, we can get the good operability range of each parameter, which is 570-600mm for L, 350-380mm for W, and 340-380mm for H.

[0060] Table 1. Contact convenience parameters for the interaction between the driver and the central control screen of different models

[0061]

[0062]

[0063] As another specific implementation method, the operational convenience evaluation model S takes the distances L, W, H between point H and the center point of the central control screen in the X, Y and Z directions, and the angle A between the central control screen and the horizontal plane as input, divides the convenience score into multiple levels, and takes the convenience level as output, based on neural network training. As an example, the neural network can adopt a multi-layer perceptron (MLP), which is composed of an input layer, multiple hidden layers and an output layer, and the neurons are fully connected; the data enters from the input layer, undergoes nonlinear transformation of the hidden layer, and finally obtains the prediction result in the output layer. L, W, H and A are used as input features, input into the multi-layer perceptron, and trained through a large amount of sample data, so that the model learns the complex nonlinear relationship between these factors and convenience, and outputs the evaluation result of convenience.

[0064] The above method can obtain a large number of training samples by collecting the operating convenience scores of the central control screen from drivers of different heights and different models on the premise that the main driver's seat is adjusted comfortably. Then, based on the main driver's seat posture parameters and the central control screen posture, an operating convenience score can be given, which has a guiding role in the design of the central control screen during the vehicle development stage.

[0065] Although the above convenience evaluation can provide a universal design solution that is suitable for most drivers, it still cannot meet the needs of some drivers, such as height or body proportions that are not covered by the training samples. In view of the fact that many existing car models are equipped with a central control screen with adjustable posture, and the vehicle control system has increasingly powerful analysis functions, the above convenience evaluation method can further adjust the posture of the central control screen or optimize the layout of the application interaction components in the central control screen after the vehicle is put into use, based on the driver's actual height, body proportions and other characteristics, so as to make the driver's operation more comfortable. Specifically, if Figure 4 As shown, the following steps are included:

[0066] Step 401: in response to the adjustment of the driver's seat posture, obtaining the current driver's seat posture parameters and the central control screen posture parameters;

[0067] Step 402: Under the current state of the driver's seat, calculate the distance between point H and the center point of the central control screen in the X direction, Y direction and Z direction;

[0068] Step 403: Evaluate the operational convenience of the driver's seat in the current state according to the operational convenience evaluation model;

[0069] Step 404: determine whether the current operation convenience score meets the set threshold. If so, do not perform any operation. If not, execute step 405.

[0070] Step 405: obtaining an interface envelope touched by fingers of the right hand of the driver when the driver is sitting in the main driving seat and in a relaxed state;

[0071] Step 406: Optimize the layout of the positions of the interactive components on the central control screen according to the interface envelope touched by the fingers of the right hand.

[0072] It can be understood that the threshold value set in step 404 is stricter than the threshold value set in the vehicle development stage above, so that the convenience level for a specific driver can be given more specifically, and then subsequent optimization can be performed.

[0073] Regarding the hand reach area, SAE has formulated relevant standards, which refers to the range of space that a person's hand can easily reach without moving the body in ergonomics. This area is crucial for the layout of the instrument screen. The range of the hand reach area is different for different human bodies. Therefore, in some embodiments, when it is inconvenient for the current driver to operate in a comfortable position suitable for driving (for example, the driver is relatively short), in step 405, the driver is guided to place his right hand on the central control screen when he is sitting in the main driver's seat and in a relaxed state, so as to obtain the coverage of the driver's right palm on the central control screen.

[0074] Taking into account the flexibility of the arm and wrist, the area that can be reached by the right hand is estimated based on the coverage range. As an implementation method, since the size of the central control screen operation area is limited, only the degree of freedom of the driver's wrist can be considered. After obtaining the area covered by the driver's palm, the wrist position can be estimated based on the coverage area, and then the range that can be covered on the central control screen operation area when the driver's palm rotates is obtained with the wrist joint as the rotation center; the central control screen operation area is grid-divided, and the grids are uniquely encoded, the coverage range is converted to screen coordinates, and the grid set that can be covered by the driver's right hand on the central control screen is determined, that is, the finger touch interface envelope.

[0075] As another implementation method, the range that can be covered by the driver's right hand is obtained by guiding the driver's right hand to swipe across the central control screen; the operation area of ​​the central control screen is divided into grids, and the grids are uniquely encoded, and the covered range is converted to screen coordinates to determine the grid set that can be covered by the driver's right hand on the central control screen, that is, the finger touch interface envelope.

[0076] In step 406, the layout of the interactive components on the central control screen is optimized according to the envelope of the finger-touched interface to ensure that the interactive components used frequently are within the reachable range. Specifically, the reachable area is divided into sub-areas according to the operating comfort. Generally speaking, the closer to the driver, the more comfortable the operation; at the same time, the functions in the central control screen are comprehensively scored, sorted according to the comprehensive score, and matched to each sub-area in order from large to small in terms of score, with high scores being preferentially matched to sub-areas with high comfort. Of course, the reasonable number of interactive components can also be determined based on the reachable range first, and then matched to the sub-areas based on the size of the comprehensive score.

[0077] As an example, at set time intervals, the user's operation logs on the central control screen are obtained, and combined with the operation logs, the functions of the central control screen are evaluated, and the evaluation indicators include at least the frequency of use in the current time period, the average usage time, the difficulty of finding, etc. Among them, the difficulty of finding is based on the cumulative number of operations required to obtain the function, and the operations include click operations and sliding operations. The deeper the level of hidden functions and the lower they are in the list, the more difficult it is to obtain, and the lower the score of the difficulty of finding. Based on these evaluation indicators, the functions in the central control screen are comprehensively scored.

[0078] In addition, when the central control screen starts various functions, if the function has interactive components, the position of the interactive components is also checked and optimized according to the area accessible by the driver's right hand. For example, the navigation function has interactive components such as inputting a destination, and the music player function has interactive components such as selecting a playlist.

[0079] The above method first determines the convenience of operating the central control screen for the current driver based on the above evaluation method. When the convenience evaluation result obviously tends to the convenience limit, it is considered that there is still room for adjustment in the operating convenience for the driver. Based on this, by obtaining the reachable range of the driver's right hand, when the interactive component is displayed on the central control screen, it can be ensured that the interactive component is within the reachable range of the driver's right hand.
