Rail vehicles are of many types, such as locomotives, passenger cars, trucks, motor train units and urban rail vehicles as mentioned above. There are different sets of evaluation indices for different vehicle types.
However, in general, basic evaluation indexes are concentrated on devices and functions such as a vehicle body, a bogie, a diesel engine, traction, control, hitch, braking, and on-vehicle electrical equipment.
In the present embodiment, each evaluation index corresponds to a different status level. E.g., the status ratings are poor, medium, good, and good. Generally, the number and content of the state levels corresponding to each evaluation index are the same.
And performing performance tests (such as running, equipment maintenance and the like) on the target vehicle within a recent period of time, collecting test data in the test process, and then obtaining a performance test score corresponding to each evaluation index in the evaluation index set according to the test data. The performance test score may be determined by a technician by analyzing the test data based on experience, or by substantially analyzing the test data and comparing it to standard information (e.g., curves, ranges).

And after the comprehensive evaluation matrix is obtained, determining an evaluation result vector according to the comprehensive evaluation matrix. In this regard, the purpose of the comprehensive evaluation matrix is to evaluate the state of the target vehicle. For this reason, the comprehensive evaluation matrix needs to perform certain calculation transformation to obtain an evaluation result vector.
In the embodiment of the present invention, the weights of different evaluation indexes may be different for the vehicle. Therefore, calculation can be carried out according to the weights of different evaluation indexes and the comprehensive evaluation matrix to obtain a required evaluation result vector. Namely, the comprehensive evaluation matrix is weighted to obtain the evaluation result vector.
After the evaluation result vector is obtained, the evaluation result vector has the effect of directly or further evaluating the state of the vehicle, for which purpose the overall state of the target vehicle is determined from the evaluation result vector.

merging the membership degree vectors corresponding to each evaluation index to obtain a comprehensive evaluation matrix;
wherein the state-level criterion table includes a criterion value for each state level.
In this regard, the above steps are explained below with specific examples:
the selected evaluation index of the vehicle was the braking state, and the performance test score of the braking state was 80. The state rank criterion table includes criterion values 60, 70, and 90 for each state rank of the braking state.
At this time, the performance test score 80 of the braking state is calculated with each standard value to obtain membership degrees corresponding to different state grades.
For example, a state rank with a standard value of 60 has a degree of membership of:
the degree of membership of the state class with the standard value of 70 is:
the membership of the state class with the standard value of 90 is:
according to the embodiment, the membership degree vectors corresponding to each evaluation index are combined to obtain the comprehensive evaluation matrix, so that the comprehensive evaluation matrix is combined with the membership conditions of different state grades under multiple indexes, the indexes are closer to the actual test condition, and the subsequent accurate evaluation of the comprehensive state of the target vehicle is facilitated.
