Method and device for establishing motor vehicle state comprehensive assessment system

Abstract

The invention discloses a method and device for establishing a motor vehicle state comprehensive assessment system. The method comprises the steps of determining operating state indexes of all set function modules of motor vehicles; extracting the public factors of the operating state indexes according to a factor analysis method, carrying out classification on the operating state indexes with the public factors as a standard, and establishing an initial motor vehicle state comprehensive assessment index system; screening the operating state indexes corresponding to all the public factors in the initial motor vehicle state comprehensive assessment index system according to stepwise regression analysis; establishing the motor vehicle state comprehensive assessment index system according to the screened operating state indexes corresponding to all the public factors. Thus, reasonable assessment can be carried out on the integral state of the motor vehicles.

Description

technical field [0001] The invention relates to the field of motor vehicles, in particular to a method and device for establishing a comprehensive evaluation system for motor vehicle status. Background technique [0002] As people pay more attention to environmental protection, motor vehicles powered by clean energy are more and more sought after by people. They have incomparable advantages in energy saving and emission reduction compared to fuel vehicles. Countries around the world have introduced various policies and measures to encourage new With the development of energy vehicles and related industries, the popularity of new energy vehicles has continued to increase. [0003] At present, motor vehicle status evaluation is divided into single index evaluation and comprehensive evaluation. Single evaluation is the process of quantifying a state characteristic of a motor vehicle to obtain an evaluation value, and the evaluation result is the index value; comprehensive evalu...
