[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] In one embodiment, Figure 1 As shown, a method for determining the damage standard of a vehicle transmission component is provided. This embodiment takes the method applied to a terminal as an example. It can be understood that the method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0043] S110. Determine the total amount of sample damage to sample transmission components of different sample vehicles during a test operation period; wherein the different sample vehicles belong to the same vehicle category.

[0044] Among them, the vehicle category can be understood as a classification system that divides vehicles into different types according to the static configuration attributes of the vehicle. The static configuration attributes may include at least one of the origin, brand, vehicle platform, vehicle line, emission type, fuel type, drive form, engine model, transmission component model and rear axle speed ratio. The transmission component model may include at least one of the gearbox model and drive axle model. It should be noted that technicians can select the corresponding static configuration attributes according to actual needs, and this application does not impose any restrictions on the type and quantity of the selected static configuration attributes. The sample transmission component may include at least one of a gearbox, a drive axle, etc.

[0045] Among them, the test operation period can be understood as a damage test on the sample transmission component within a set time length. The total sample damage amount represents the total amount of damage accumulated after the sample transmission component has undergone a damage test for a set time length. Among them, the damage test can be a fatigue test, which refers to applying repeated or periodic loads to the sample transmission component within a set time length to determine the gradually accumulated damage value of the sample transmission component. The set time length can be set by technical personnel according to needs or experience, or determined through a large number of experiments, and this application does not impose any restrictions on this.

[0046] In an optional embodiment, the total amount of sample damage to sample transmission components of different sample vehicles during a test operation period is determined, including: for each sample transmission component, obtaining test data of the sample transmission component at each test time point during the test operation period; for each test time point, determining the damage value of the sample transmission component at the corresponding test time point based on the test data corresponding to the test time point; and determining the total amount of sample damage to the corresponding sample transmission component during the test operation period based on the damage values ​​corresponding to all test time points during the test operation period.

[0047] Wherein, the test data includes the input speed, input torque and SN (Stress-Number of Cycles Curve) curve coefficient of the sample transmission component at the corresponding test time point. The SN curve is used to describe the fatigue performance of the material under cyclic stress or cyclic strain. The SN curve coefficient is used to represent the relevant parameters between stress and life. Exemplarily, the sample transmission component can be a gearbox, and the test data includes the gearbox input speed, gearbox input torque and the corresponding SN curve coefficient at the corresponding test time point. Exemplarily, the sample transmission component can be a drive axle, and the test data includes the drive axle input speed, drive axle input torque and the corresponding SN curve coefficient at the corresponding test time point.

[0048] Among them, the damage value of the sample transmission component at the corresponding test time point can be determined based on the test data corresponding to the test time point and the Miner damage theorem. The damage values ​​of the sample transmission components at all test time points are summed to obtain the total sample damage during the test operation period.

[0049] In an optional embodiment, the damage value of the sample transmission component at the corresponding test time point can be calculated by the following formula:

[0050] ;

[0051] Wherein, S represents the damage value of the sample transmission component at the corresponding test time point; T represents the input torque of the sample transmission component; N represents the input speed of the sample transmission component, that is, the number of rotations of the sample transmission component input in one second; Indicates the SN curve coefficient.

[0052] S120. Based on the total amount of damage of each sample, determine at least one damage level interval corresponding to the transmission component of the sample; each damage level interval corresponds to a damage level.

[0053] The number of damage level intervals can be set by technicians according to needs or experience, or determined through a large number of experiments, and this application does not impose any limitation on this. For example, four damage level intervals can be set, that is, four damage levels can be set.

[0054] In an optional embodiment, at least one damage level interval corresponding to the sample transmission component may be determined based on the distribution of the total amount of damage of each sample.

[0055] S130. For each damage level interval, determine the standard range of the target object to be evaluated at the corresponding damage level based on the numerical range of the total amount of sample damage within the damage level interval; wherein the target object includes the target transmission component of the target vehicle; the target vehicle and the sample vehicle belong to the same vehicle category; and the target transmission component and the sample transmission component belong to the same component category.

[0056] In an optional embodiment, the numerical range of the total amount of sample damage within the damage level interval may be used as a standard range for evaluating the target object at the corresponding damage level.

[0057] In the embodiment of the present application, by determining the total amount of sample damage of sample transmission components of different sample vehicles during the test operation period, an original reference is provided for determining the damage standard. At the same time, since the different sample vehicles belong to the same vehicle category, the total amount of sample damage corresponding to each sample transmission component is ensured to have high comparability and reference. By determining at least one damage level interval corresponding to the sample transmission component based on the total amount of damage of each sample, the standard range of the evaluation target object at the corresponding damage level is determined for each damage level interval according to the numerical range of the total amount of sample damage within the damage level interval. It provides an objective and accurate standard for the damage assessment of transmission components, and the evaluation process does not need to introduce subjective judgment of the evaluator.

[0058] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment, in which the steps for determining the damage level interval are refined.

[0059] See also Figure 2 The steps for determining the damage level range shown include:

[0060] S210, determining the distribution data of the total damage amount of each sample under the target mathematical distribution.

[0061] Among them, the target mathematical distribution is the probability distribution, which is a mathematical function used to describe the regularity of the values ​​of random variables.

[0062] In an optional embodiment, the target mathematical distribution is determined by the following steps: determining at least one preset mathematical distribution; for each preset mathematical distribution, determining the P value and KS statistic of the total sample damage corresponding to each sample vehicle under the preset mathematical distribution; from the preset mathematical distributions corresponding to the P values ​​less than the preset values, selecting the preset mathematical distribution with the smallest corresponding KS statistic as the target mathematical distribution.

[0063] Among them, the P value and KS statistic can be understood as statistical parameters used to evaluate the statistical relationship or difference between sample data and overall data, or between different sample data. The P value is used to characterize the probability of obtaining a result equal to or more extreme than the current observation through random sampling under the condition that the null hypothesis is true. If the P value is less than the preset value, the corresponding preset mathematical distribution can be considered to be significant. It should be noted that the preset value can be set by technicians according to needs or experience, or determined through a large number of experiments, and this application does not impose any restrictions on this. In particular, the preset value can be set to 0.05. The smaller the KS (Kolmogorov-Smirnov) statistic, the more it matches the preset mathematical distribution with the sample data.

[0064] The preset mathematical distribution may include at least one of normal distribution, Poisson distribution, Weibull distribution, lognormal distribution, exponential distribution, uniform distribution, gamma distribution and chi-square distribution.

[0065] S220, dividing the distribution data into intervals to obtain at least one damage level interval corresponding to the sample transmission component.

[0066] In an optional embodiment, the distribution data is divided into intervals to obtain at least one damage level interval corresponding to the sample transmission component, including: obtaining the total amount of sample damage located at at least one preset quantile position from the distribution data; and determining at least one damage level interval based on the total amount of sample damage at each preset quantile position.

[0067] Optionally, the total sample damage amount at each preset quantile position, the minimum sample damage amount and the maximum sample damage amount in the distribution data can be used as the boundaries of the level interval, thereby dividing the corresponding number of damage level intervals.

[0068] Among them, the number and specific values ​​of the preset quantiles can be set by the technicians according to needs or experience, or determined through a large number of experiments, and this application does not impose any restrictions on this. In particular, there are three preset quantiles, namely the 25th quantile, the 50th quantile and the 70th quantile. The total amount of sample damage corresponding to the minimum sample damage amount to the 25th quantile is taken as the first damage level interval, and the damage level is level one; the total amount of sample damage corresponding to the 25th quantile to the total amount of sample damage corresponding to the 50th quantile is taken as the second damage level interval, and the damage level is level two; the total amount of sample damage corresponding to the 50th quantile to the total amount of sample damage corresponding to the 70th quantile is taken as the third damage level interval, and the damage level is level three; the total amount of sample damage corresponding to the 70th quantile to the maximum sample damage is taken as the fourth damage level interval, and the damage level is level four. Among them, the larger the damage level, the higher the degree of damage to the transmission component, and the worse the evaluation.

[0069] In the embodiment of the present application, by determining the distribution data of the total damage amount of each sample under the target mathematical distribution and dividing the distribution data into intervals, the damage level intervals obtained based on this can more objectively and accurately reflect the damage level of the transmission component.

[0070] The above process mainly involves a method for determining the damage standard of a vehicle transmission component. In one embodiment, Figure 3 As shown, a damage assessment method for a vehicle transmission component is provided, the method comprising:

[0071] S310: Determine the target total amount of damage to the transmission component to be evaluated in the target vehicle during the evaluation operation period.

[0072] S320: Obtain the vehicle category of the target vehicle.

[0073] S330: Obtain the standard range of each damage level interval of the transmission component to be evaluated under the vehicle category.

[0074] S340. Determine the target damage level interval to which the target total damage amount belongs based on the standard range of each damage level interval.

[0075] S350: Evaluate the transmission component to be evaluated to a damage level corresponding to the target damage level range.

[0076] The standard range is determined based on the above-mentioned method for determining the damage standard of vehicle transmission components. The target vehicle can be understood as a vehicle that needs to be assessed for damage. In particular, the target vehicle can be a used vehicle.

[0077] It can be understood that based on the above-mentioned method for determining the damage standard of vehicle transmission components, the standard ranges of each damage level interval of different target transmission components under different vehicle categories can be determined. Therefore, when evaluating the transmission components to be evaluated in the target vehicle, it is only necessary to find the standard ranges of each damage level interval that matches the vehicle category of the target vehicle and the type of transmission components to be evaluated, so as to determine the target damage level interval to which the target total amount of damage belongs and the corresponding damage level.

[0078] In an optional embodiment, the length of the evaluation operation period and the time length of the test operation period may be different. In this case, the standard range of the target damage level interval may be corrected according to the ratio of the time length of the evaluation operation period to the time length of the test operation period. In another optional embodiment, the length of the evaluation operation period and the time length of the test operation period may be the same, so as to directly determine the target damage level interval to which the target damage amount belongs.

[0079] In an optional embodiment, the damage standard determination method further includes: obtaining the damage level of each transmission component to be evaluated in the target vehicle; and evaluating the vehicle condition of the target vehicle according to the damage level of each transmission component to be evaluated.

[0080] The type and quantity of each transmission component to be evaluated can be set based on actual needs, and this application does not impose any restrictions on the type and quantity of each transmission component to be evaluated. In particular, each transmission component to be evaluated includes a gearbox and a drive axle.

[0081] Among them, the damage level of each transmission component to be evaluated can reflect the condition of the target vehicle to a certain extent, and provide a reliable basis for evaluating the condition of the target vehicle.

[0082] In an embodiment of the present application, by obtaining the standard range of each damage level interval of the transmission component to be evaluated under the vehicle category of the target vehicle, and based on the standard range of each damage level interval, the target damage level interval to which the target total amount of damage belongs is determined, thereby being able to objectively and accurately determine the damage level of the transmission component to be evaluated without introducing the subjective judgment of the evaluator.

[0083] Based on the technical solutions of the above-mentioned embodiments, the present application also provides an optional embodiment, in which another specific implementation method of the method for determining the damage standard of vehicle transmission components is provided.

[0084] See also Figure 4 Another method for determining the damage standard of a vehicle transmission component shown includes:

[0085] S410. Determine the total amount of sample damage to sample transmission components of different sample vehicles during a test operation period; wherein the different sample vehicles belong to the same vehicle category.

[0086] S420. Determine at least one preset mathematical distribution.

[0087] S430. For each preset mathematical distribution, determine the P value and KS statistic of the total amount of sample damage corresponding to each sample vehicle under the preset mathematical distribution.

[0088] S440. From the preset mathematical distributions corresponding to P values ​​less than the preset value, select the preset mathematical distribution with the smallest corresponding KS statistic as the target mathematical distribution.

[0089] S450, determining the distribution data of the total damage amount of each sample under the target mathematical distribution.

[0090] S460. Obtain the total amount of sample damage located at at least one preset quantile position from the distribution data.

[0091] S470. Determine at least one damage level interval based on the total amount of sample damage at each preset quantile position; each damage level interval corresponds to a damage level.

[0092] S480. For each damage level interval, determine the standard range of the target object to be evaluated at the corresponding damage level based on the numerical range of the total amount of sample damage within the damage level interval; wherein the target object includes the target transmission component of the target vehicle; the target vehicle and the sample vehicle belong to the same vehicle category; and the target transmission component and the sample transmission component belong to the same component category.

[0093] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
