[0045] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0046] like Figure 1 The flowchart of the functional safety controllability rating standard optimization method shown in the figure includes:

[0047] Step 1: Obtain controllability test data of different drivers in the standard area and the evaluation area under the same scenario;

[0048] Step 2: Count the proportion of controllable personnel in the standard area and the evaluation area according to the controllability test data;

[0049] Step 3: Based on the known controllability level standards of the standard area, determine the controllability level standards of the assessment area according to the corresponding controllable personnel ratios of the standard area and the assessment area.

[0050] Specifically, first, you can run a simulation scenario on the test platform or a real vehicle scenario on a real vehicle road, and arrange multiple drivers of different types in the evaluation area and the standard area to conduct the test, so as to obtain the controllability test data of multiple drivers in the standard area and the evaluation area under the same test scenario. Then, based on the corresponding controllability test data, it is determined whether different drivers can effectively control the vehicle with the assistance of the vehicle system, and then the proportion of controllable personnel in the standard area and the evaluation area is calculated based on the number of people who can effectively control the vehicle in the evaluation area and the standard area. Finally, by comparing the proportion of controllable personnel in the standard area and the evaluation area, the difference in controllability caused by factors such as the driver's driving level and takeover ability can be determined, and then the controllability level standard of the standard area can be optimized and adjusted to obtain the rating standard applicable to the evaluation area, thereby ensuring the accuracy of subsequent rating results.

[0051] For example, Europe can be used as the standard region and my country can be used as the evaluation region. By comparing the proportion of controllable personnel in Europe with the proportion of controllable personnel in my country, the difference in controllability between the European population and the Chinese population can be determined. By adjusting the European standard that has been used internationally through the obtained controllability difference value, the controllability level standard applicable to my country can be obtained. This avoids the direct use of the European standard, and the impact of the difference in driving level between the European population and the Chinese population on the functional safety controllability rating results.

[0052] In this embodiment, optionally, determining the controllability level standard of the assessment area includes:

[0053] According to the corresponding controllable personnel ratios of the standard area and the assessment area, the controllable ratio difference between the standard area and the assessment area is calculated. The specific calculation formula is as follows:

[0054]

[0055] M1 and M2 are the total number of drivers participating in the test in the standard area and the evaluation area respectively; N1 and N2 are the corresponding number of controllable personnel in the standard area and the evaluation area respectively.

[0056] Based on the standard threshold corresponding to the known controllability standard of the standard area, the controllability level standard of the evaluation area is determined according to the controllable ratio difference value. The specific calculation formula is as follows:

[0057]

[0058] Among them, D1 and D2 are the controllability level standard thresholds corresponding to the standard area. In the European standard, D1 and D2 are 99% and 90% respectively. C1, C2, and C3 are controllability levels.

[0059] like Figure 2 The flowchart of the functional safety controllability rating method shown in the figure includes:

[0060] Step S1, using the above functional safety controllability rating standard optimization method to determine the controllability grade standard of the assessment area;

[0061] Step S2, obtaining controllability test data of multiple drivers of different categories in the evaluation area, and determining the personnel behavior characteristic parameters corresponding to the drivers in the evaluation area through all the controllability test data;

[0062] Step S3: Determine the proportion of controllable personnel corresponding to the vehicle system through the personnel behavior characteristic parameters, and match the proportion of controllable personnel with the controllability level standard of the assessment area to determine the functional safety controllability level of the vehicle system.

[0063] Specifically, first, the above-mentioned functional safety controllability rating standard optimization method can be used to determine the functional safety controllability rating standard applicable to the evaluation area under different test scenarios to ensure the accuracy of subsequent rating results. Then, simulation scenarios can be run on the test platform or real vehicle scenarios can be run on real vehicle roads, and multiple drivers of different categories in the evaluation area can be arranged for testing, such as gender, age, driving level, etc., so as to obtain test data of multiple drivers of different categories operating vehicles under the test scenario.

[0064] By statistically analyzing all the acquired test data, the human behavior characteristic parameters of the driver controlling the vehicle in the assessment area under the corresponding test scenario can be determined. Finally, the controllable personnel ratio of the vehicle system can be determined through the human behavior characteristic parameters, and the obtained controllable personnel ratio can be matched with the functional safety controllability rating standard corresponding to the assessment area to determine the functional safety controllability level of the vehicle.

[0065] In this embodiment, the personnel behavior characteristic parameters may include: vehicle dynamic parameters, relative relationship parameters, driver reaction time and takeover effectiveness.

[0066] Among them, the driver's reaction time includes the time from the occurrence of the fault to the driver's start of risk avoidance operation, which is used to evaluate the reaction ability of different drivers.

[0067] Vehicle dynamic parameters include the position, speed, acceleration and other parameters of the main vehicle, which are used to assist in evaluating whether a hazardous event has occurred in the vehicle.

[0068] Relative relationship parameters include parameters such as relative position and relative speed with other traffic participants, as well as parameters such as relative position with lane lines, which are used to determine whether a vehicle has encountered a hazardous event.

[0069] The effectiveness of the takeover is determined by comprehensively evaluating whether the driver's operation is effective, and is used to determine whether the driver's operation can avoid injuries.

[0070] In this embodiment, optionally, determining the proportion of controllable personnel corresponding to the vehicle system under the control of the driver in the assessment area through the personnel behavior characteristic parameters includes:

[0071] Based on the mapping relationship between the set personnel behavior characteristic parameters and the controllable personnel ratio, the controllable personnel ratio corresponding to the vehicle system is determined according to the personnel behavior characteristic parameters corresponding to the drivers in the assessment area.

[0072] Specifically, after obtaining the personnel behavior characteristic parameters, the mapping relationship between the set personnel behavior characteristic parameters and the controllable personnel ratio can be used to determine the corresponding controllable personnel ratio of the vehicle system under the control of the driver in the assessment area according to the obtained personnel behavior characteristic parameters.

[0075] Classifying all drivers based on the personnel behavior characteristic parameters, and counting the proportion of controllable personnel corresponding to the personnel behavior characteristic parameters of different categories;

[0076] By performing function fitting on the controllable personnel ratios corresponding to all personnel behavior characteristic parameters, a mapping relationship between the personnel behavior characteristic parameters and the controllable personnel ratios is determined.

[0077] Specifically, first, we can obtain multiple controllability test data of different categories of drivers in the evaluation area under the corresponding test scenario as a sample set, and perform feature extraction on all the controllability test data in the sample set, so as to determine the personnel behavior characteristic parameters of different drivers operating the vehicle under the corresponding test scenario. Then, all drivers are classified based on the personnel behavior characteristic parameters, so as to determine the number of drivers and the number of controllable personnel corresponding to different personnel behavior characteristic parameters. According to the corresponding number of drivers and the number of controllable personnel, the proportion of controllable personnel corresponding to different behavior characteristic parameters can be calculated. Finally, the proportion of controllable personnel corresponding to different behavior characteristic parameters is fitted with a function to determine the mapping relationship between the personnel behavior characteristic parameters and the proportion of controllable personnel.

The standard optimization module can determine the controllability differences caused by factors such as the driver's driving level and takeover ability by comparing the proportion of controllable personnel in the standard area and the evaluation area, and then optimize and adjust the controllability level standard of the standard area to obtain the rating standard applicable to the evaluation area, thereby ensuring the accuracy of subsequent rating results.
