Abstract:

Taking the vehicle's handling and stability performance targets as research object,the theory of multi-variate statistical analysis was used to find the relationship of the targets each other.Several new handling targets are rebuilt sorted by their importance based on the idea of decreasing dimension,and then the vehicle's handling centesimal system score was get by the objective weighting method.The results show that it's available to evaluate the vehicle's handling performance using fewer targets and the weighting score.

Key words: vehicle engineering, principal component analysis(PCA), factor analysis, handling performance target, objective weighting
