New energy automobile operation safety performance evaluation system construction method

The invention discloses an operation safety evaluation system construction method based on new energy automobile whole-automobile data, and the method comprises the steps: carrying out the abnormal data screening of data generated in an automobile operation process through a DBSCAN algorithm, and then carrying out the standardization of the data; classifying the data in the operation process of the new energy vehicle according to the safety category, calculating the weight of each data index for safety performance evaluation, and selecting a plurality of indexes with the maximum weight as characteristic indexes for evaluating the safety performance; using a Bayesian network to establish a new energy vehicle operation safety performance evaluation model, using data of passing faulty vehicles to verify accuracy of model evaluation, and correcting the model to improve precision of model evaluation. According to the method, the data generated in the vehicle operation process is collected, the new energy vehicle w
