[0065] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0066] Existing technologies lack a systematic and quantitative assessment method to evaluate whether the viewing angle and overall field of view of the information displayed in a Head-Up Display (HUD) affect the driver's operation. To address this technical problem, this invention performs a test task on the HUD and acquires test data during the test. This test data includes behavioral data, time information, and display data from the projection screen. First evaluation information input for the test task is then acquired. Based on the test data and the first evaluation information, second evaluation information is determined for the HUD operation in a preset simulated scenario. This allows for a systematic evaluation of the information displayed by the HUD using both test data and subjective evaluation information.

[0067] Reference Figure 1 The diagram illustrates a flowchart of a head-up display evaluation method according to an embodiment of the present invention. This method is applied to a server connected to a driving simulator and a projection screen. Specifically, the method may include the following steps:

[0068] In this invention, the head-up display (HUD) can be evaluated before being installed in a vehicle. This evaluation requires setting up an evaluation scenario, which can be conducted in a dimly lit and open space. This evaluation scenario may include a server, a driving simulator, and a projection screen, and may also include a computer terminal. Figure 2The diagram illustrates an evaluation scenario provided by an embodiment of the present invention. A computer terminal 1 is connected to a server 3, a driving simulator 2 is connected to the server, a projection screen 4 is connected to the server, and 5 represents the test numbers displayed on the projection screen. The computer terminal can be used by the evaluator to select the simulation scenario and input data. The simulation device can include a steering wheel, accelerator, clutch, and brake pedal with multiple buttons. The server can store multiple preset simulation scenarios and can also acquire and process relevant data. The preset simulation scenarios can be designed based on the driving software VTD (Virtual Test Drive). Each simulation scenario can have a corresponding test task. The projection screen is used to project the simulation scenarios.

[0069] Different scenarios can be designed in the simulation environment according to requirements. For example... Figure 3 The diagram illustrates a simulated road scenario provided by an embodiment of the present invention. The road is designed as a two-way four-lane road with a width of 3.5 meters on each side, spanning 50 km and consisting of 7 curves: 3 left turns and 4 right turns, all with the same curvature. After the road design is completed, scenery, vehicle shapes, and traffic flow can be designed along both sides of the road in the simulation scenario, making the simulation scenario more realistic. To make the evaluation results more accurate, various simulation scenarios can be designed, including: scenarios with traffic flow, no traffic flow, speed limit, no speed limit, daytime, and various combinations thereof. For example, simulation scenario one is a daytime scenario with traffic flow and a speed limit.

[0070] Step 101: Invoke the projection screen to perform head-up display in a preset simulated scenario, and execute a test task for the head-up display through the simulated driving device.

[0071] In this embodiment of the invention, after the evaluation scenario is set up, the evaluator can start evaluating the head-up display. At this time, the server can call the projection screen to display the simulated scenario on the projection screen. The evaluator can perform test tasks for the head-up display through the driving simulator. The test tasks can include multiple test tasks corresponding to multiple preset simulated scenarios. After one test task is completed, the next test task continues until all test tasks are completed.

[0072] Step 102: Obtain test data during the test task; the test data includes: behavioral data, time information, and display data of the projection screen.

[0073] In this embodiment of the invention, the evaluator can obtain test data corresponding to the test task during the execution of the test task. The test data may include behavioral data, time information, and display data of the projection screen.

[0074] Step 103: Obtain the first evaluation information for the test task input of the head-up display.

[0075] In this embodiment of the invention, after the test task is completed, a first evaluation of the test task input for the head-up display can be obtained, and the first evaluation can be input by the evaluator through the aforementioned computer terminal.

[0076] Step 104: Based on the test data and the first evaluation information, determine the second evaluation information for head-up display in the preset simulation scenario.

[0077] In this embodiment of the invention, after obtaining the first evaluation information, a second evaluation can be determined based on the obtained test data and the first evaluation information for head-up display in a preset simulated scenario.

[0078] In this embodiment of the invention, a head-up display is performed in a preset simulated scenario using a projection screen, and a test task for the head-up display is executed using a driving simulator. Test data is acquired during the test task, including behavioral data, time information, and display data from the projection screen. First evaluation information for the test task input of the head-up display is acquired. Based on the test data and the first evaluation information, second evaluation information for the head-up display in the preset simulated scenario is determined. Therefore, when evaluating the head-up display, a systematic evaluation is performed based on the test data and the subjective first evaluation information, making the evaluation results more standardized.

[0079] Reference Figure 4 The diagram illustrates a flowchart of another head-up display evaluation method provided by an embodiment of the present invention. This method is applied to a server connected to a driving simulator and a projection screen. Specifically, the method may include the following steps:

[0080] Step 401: Invoke the projection screen to perform head-up display in a preset simulated scenario, and execute a test task for the head-up display through the simulated driving device.

[0081] In this embodiment of the invention, step 401 is the same as step 101 described above, and will not be repeated here.

[0082] Step 402: During the test task, test numbers are randomly displayed on the projection screen, and the first time sub-information and coordinate information corresponding to the test numbers are recorded.

[0083] In this embodiment of the invention, during the testing task, test numbers can be randomly displayed on the projection screen, and the first time sub-information and coordinate information corresponding to the occurrence of the test numbers can be recorded. The test numbers can be labeled when they appear for subsequent statistical processing. For example, during the evaluation process, the evaluator can randomly display test numbers "6" and "9". When a test number appears, the first time sub-information and coordinate information corresponding to the test number are recorded simultaneously, and the test numbers can be labeled to form corresponding data information. For example, the test number labeled 1 is "6", the corresponding time is 10 seconds, and the corresponding coordinate information is (0,1). The coordinate information is based on the display coordinate information of the projection screen.

[0084] Step 403: Obtain the input number when the test number appears, as well as the second time sub-information and behavior data corresponding to the input number.

[0085] In this embodiment of the invention, when test numbers are randomly displayed on the projection screen, the evaluator can input the corresponding input numbers. In this invention, the steering wheel of the driving simulator can be equipped with multiple physical buttons, which can be used to input numbers. For example, the steering wheel of the driving simulator has two physical buttons, one corresponding to the number "6" and the other to the number "9". When the test number "6" randomly appears on the projection screen, the user can press the physical button corresponding to the number "6" to complete the input. While inputting numbers, the second time sub-information and behavioral data corresponding to the input numbers can be acquired simultaneously. The behavioral data can include: driving speed, acceleration, position offset, steering wheel angle, brake pedal angle, and accelerator pedal position.

[0086] Step 404: After the test task is completed, obtain the first evaluation sub-information and the second evaluation sub-information for the coordinate information input to display the test numbers.

[0087] In this embodiment of the invention, after the test task is completed, the evaluator can evaluate the coordinate information of the displayed test numbers, and this evaluation may include a score. The evaluator can input first evaluation sub-information and second evaluation sub-information through a computer terminal, thereby enabling the server to obtain the first evaluation sub-information and the second evaluation sub-information. The first evaluation sub-information may be evaluation information regarding the perceptibility of the coordinate information, and the second evaluation sub-information may be evaluation information regarding the suitability of the coordinate information.

[0088] Step 405: Based on the behavioral data, determine the behavioral index corresponding to the behavioral data.

[0089] In this embodiment of the invention, the server obtains the first evaluation sub-information and the second evaluation sub-information, and can determine the behavior index corresponding to the behavior data based on the obtained behavior data.

[0090] In one example, the behavior index can be determined as follows: based on a first preset scoring standard and behavior data, a first score corresponding to the behavior data is determined; based on the first score, a behavior index corresponding to the behavior data is determined. Specifically: driving speed, acceleration, position offset, steering wheel angle, brake pedal angle, and accelerator pedal position in the behavior data can be scored based on the preset scoring standard to obtain their respective first scores. Then, the behavior index corresponding to the behavior data is determined through the relationship between the first scores and a first preset function. For example, if the first scores for driving speed, acceleration, position offset, steering wheel angle, brake pedal angle, and accelerator pedal position are all 0.1, and the first preset function is to calculate the behavior index corresponding to the behavior data by summing the scores of all scoring objects and dividing by the number of scoring objects, then the behavior index corresponding to the behavior data can be calculated as 0.1. The specific formula for the first preset function is not specifically limited here and can be set according to the actual evaluation.

[0091] Step 406: Determine the corresponding visual index based on the first time sub-information corresponding to the test number, the second time sub-information corresponding to the input number, the test number, and the input number.

[0092] In this embodiment of the invention, after determining the behavioral index, the corresponding visual index can be determined based on the first time sub-information corresponding to the test number, the second time sub-information corresponding to the input number, the test number, and the input number.

[0093] In one example, the visual index can be determined as follows: Reaction time is determined by displaying the first time sub-information corresponding to the test number and the second time sub-information corresponding to the input number; accuracy is determined using the test number and the input number; based on a second preset scoring standard, reaction time, and accuracy, a second score corresponding to the reaction time and a third score corresponding to the accuracy are determined; and the corresponding visual index is determined based on the second and third scores. For example, if the reaction time is determined to be 0.5 seconds and the accuracy is 80%, the second preset scoring standard is that a second score of 0.2 is given when the reaction time is less than or equal to 0.5 seconds, and a third score of 0.1 is given when the accuracy is greater than or equal to 80%. After obtaining the second and third scores, the corresponding visual index can be calculated based on the second and third scores and a second preset function. For example, if the second preset function is the sum of the second and third scores as the visual index, then the visual index can be calculated to be 0.3. The specific formula for the second preset function is not specifically limited in this invention and can be set according to the actual evaluation.

[0094] Step 407: Determine the corresponding evaluation index based on the first evaluation sub-information and the second evaluation sub-information.

[0095] In this embodiment of the invention, after determining the visual index, the corresponding evaluation index can be determined based on the first evaluation sub-information and the second evaluation sub-information. Specifically, the evaluation index can be determined as follows: based on the third preset scoring standard, the first evaluation sub-information, and the second evaluation sub-information, determine the score corresponding to the first evaluation sub-information and the score corresponding to the second evaluation sub-information; then, based on the third preset function, the score corresponding to the first evaluation sub-information, and the score corresponding to the second evaluation sub-information, calculate the corresponding evaluation index. The specific formula for the third preset function is not specifically limited in this invention and can be set according to the actual evaluation process.

[0096] Step 408: Based on the behavior index, the visual index, and the evaluation index, determine the second evaluation information for head-up display in the preset simulation scenario.

[0097] In this embodiment of the invention, after determining the behavior index, visual index, and evaluation index, a second evaluation information for head-up display in a preset simulated scenario can be determined based on the behavior index, visual index, and evaluation index.

[0098] In one example, the second evaluation information for head-up display in a preset simulation scenario can be determined as follows: based on the behavioral index, visual index, and evaluation index, a fourth score for head-up display in the preset simulation scenario is determined; according to the fourth score and the preset evaluation table, the corresponding second evaluation information is output. When determining the fourth score for head-up display in the preset simulation scenario, it can be calculated according to the following formula (1):

[0099] Y = a1(1-D) + a2(1-R) ​​+ a3(1-C) Formula (1)

[0100] Wherein, Y is the fourth score for head-up display in a preset simulated scenario, a1 to a3 represent the weights of the corresponding indices, D is the behavioral index, R is the visual index, and C is the evaluation index. The specific numerical values ​​for the weights in this invention are not specifically limited here and can be set according to the actual evaluation.

[0101] After obtaining the fourth score for head-up display in the preset simulation scenario, the corresponding evaluation information can be determined in Table (1) below, and the evaluation information can be output.

[0102]

[0103] Table (1)

[0104] For example, if the fourth score for head-up display (HUD) in a preset simulated scenario is determined to be 0.9, then based on the fourth score and the preset evaluation table, the corresponding evaluation information can be determined as follows: "HUD has high usability in the preset simulated scenario; information presentation does not affect driving behavior, does not interfere with the driver's visual perception, and can quickly and timely deliver information to the driver; the driver has a high evaluation of the overall perceptibility and appropriateness of the information presentation perspective." This evaluation information is then output. This completes the evaluation of HUD in the preset simulated scenario. During the evaluation, a systematic assessment of HUD can be conducted using test data and subjective evaluation information.
