[0057] Example 1

[0058] like Figure 1 As shown, in the first embodiment of the present invention, the invention provides the following technical solution: a method for evaluating shift performance, the method comprising:

[0059] S1. Obtain the vehicle's shift performance parameters and call the corresponding standard rating database based on the shift performance parameters;

[0060] Specifically, the shifting performance parameters include static selection force value, shifting force value, disengagement force value, static selection force feel, shifting force feel, disengagement force feel, static shifting travel, static shifting travel feel, dynamic shifting impulse, dynamic secondary impact, dynamic shifting feel, and other shifting feel;

[0061] Among them, the static gear selection force, gear shifting force, and gear disengagement force are specifically the friction, smoothness of the gear shifting process, gentleness of the gear shifting end, and loudness of the gear shifting sound; the static gear shifting stroke is specifically the gear position clarity, gear position accuracy after engaging, ability to shift at an angle, and ergonomics of the gear shift lever; the dynamic gear shifting feel is specifically the gear shifting smoothness; and other gear shifting feel is specifically the sucking sensation and play.

[0062] Understandably, the aforementioned shifting performance parameters can all be obtained through vehicle testing after the vehicle design and production are completed.

[0063] S2. Determine the scoring position of the shift performance parameter in the corresponding standard scoring database, and determine the evaluation score of the shift performance parameter based on the scoring position;

[0064] like Figure 2 As shown, step S2 includes:

[0065] S21. Arrange the first performance index in the standard scoring database according to its size to obtain the sorting database;

[0066] Specifically, each shift performance parameter has a corresponding standard rating database. The standard rating database stores the specific evaluation indicators for that shift performance parameter, such as the static shift force value, which can be between 10N and 20N. Therefore, the first performance indicator is each value between 10N and 20N.

[0067] S22. Assign scores to the second performance index in the permutation database to obtain the evaluation score corresponding to the second performance index;

[0068] Specifically, after arranging the first performance indicators according to their size, the second performance indicators are obtained. Each performance indicator can be assigned a score, which ranges from 0 to 10. The corresponding second performance indicators are then assigned the corresponding evaluation score according to their size order.

[0069] S23. Determine the superiority / inferiority judgment logic of the permutation database, and calculate the score position of the shift performance parameter in the permutation database based on the superiority / inferiority judgment logic;

[0070] Specifically, since the second performance indicators are arranged in descending order, their corresponding evaluation scores are also arranged in descending order. However, the value of different second performance indicators is not necessarily better the larger it is. Therefore, there are first and second good / bad judgment logics. When the first good / bad judgment logic is met, it indicates that the larger the value of the second performance indicator, the better the performance. When the second good / bad judgment logic is met, it indicates that the smaller the value of the second performance indicator, the better the performance.

[0071] like Figure 3 As shown, step S23 includes:

[0072] S231. When the arrangement database meets the first superiority / inferiority judgment logic, then the scoring position... for:

[0073] ;

[0074] S232. When the permutation database conforms to the second superiority / inferiority judgment logic, the scoring position is... for:

[0075] ;

[0076] In the formula, The number of second performance indicators. As the second performance indicator, These are the parameters for shift performance.

[0077] S24. Determine the evaluation score of the shift performance parameter based on the scoring position and the score to be evaluated;

[0078] Specifically, after obtaining the scoring position, the evaluation score of the shift performance parameter can be obtained based on the corresponding score to be evaluated. Each shift performance parameter needs to go through the above step S2 to obtain the evaluation score corresponding to each shift performance parameter.

[0079] It is worth noting that, for ease of understanding, this embodiment introduces specific shifting performance parameters and their corresponding evaluation scores, as detailed in Table 1:

[0080] Table 1

[0081]

[0082] S3. Determine whether the evaluation scores of the shift performance parameters are all greater than the preset standard scores;

[0083] Specifically, after obtaining the corresponding evaluation score, it is necessary to determine whether there are any shift performance parameters with evaluation scores lower than the preset standard score. In this embodiment, the evaluation score ranges from 0 to 10 points, while the preset standard score is 6 points.

[0084] S4. If the evaluation scores of the shift performance parameters are all greater than the preset standard scores, then the evaluation scores of the shift performance parameters are weighted and analyzed to obtain a shift score, and a first score report is output.

[0085] Specifically, when the evaluation scores of the shift performance parameters are all greater than the preset standard scores, it indicates that the shift performance parameters are basically qualified. Since there are multiple evaluation scores, they need to be weighted and analyzed to obtain the final shift score. Then, the first score report indicating that the shift performance is qualified is output, and the degree of excellence of the shift performance is judged based on the size of the final shift score.

[0086] Step S4 includes:

[0087] The shift performance parameters are weighted and analyzed using a first preset formula to obtain a shift score.

[0088] ;

[0089] In the formula, For gear shifting scores, The number of shift performance parameters, For the first Each parameter weight, No. Each assessment score;

[0090] It is worth noting that, for ease of understanding, this embodiment introduces shift performance parameters and their corresponding weights, as detailed in Table 2:

[0091] Table 2

[0092]

[0093] As shown in Table 2, each shift performance parameter has a corresponding parameter weight, and the final shift score is 7.6 points.

[0094] S5. If the evaluation scores of the shift performance parameters are not all greater than the preset standard scores, then output a second scoring report.

[0095] Specifically, if the evaluation scores of the shift performance parameters are not all greater than the preset standard scores, it indicates that there is at least one unqualified parameter among the shift performance parameters. Therefore, there is no need to perform weighted analysis. It is only necessary to select the lowest evaluation score as the final shift score, and finally output a second score report indicating unqualified performance.

[0096] The advantage of this embodiment is that: This application obtains the shift performance parameters of a vehicle, calls the corresponding standard scoring database based on the shift performance parameters, determines the scoring position of the shift performance parameters in the corresponding standard scoring database, and determines the evaluation score of the shift performance parameters based on the scoring position. Then, it determines whether the evaluation scores of the shift performance parameters are all greater than the preset standard score. If the evaluation scores of the shift performance parameters are all greater than the preset standard score, a weighted analysis is performed on the evaluation scores of the shift performance parameters to obtain a shift score, and a first scoring report is output. If the evaluation scores of the shift performance parameters are not all greater than the preset standard score, a second scoring report is output. This invention uses a complete set of methods for rating shift performance. By comparing the input shift performance parameters with the data in the standard scoring database to obtain the evaluation score, and then weighting the evaluation scores to output the final shift score, the accuracy of shift performance evaluation is improved, and the efficiency of vehicle shift performance testing is increased.
