Application of improved radar chart evaluation method on evaluation of automobile comprehensive performances

The qualitative and quantitative evaluations of the automobile comprehensive performance were performed using the radar chart comprehensive evaluation method. The dynamic performance, the fuel economy, the driving safety, the handling stability and the ride comfort were chosen as the evaluation indexes, a reasonable evaluation system was established. The evaluation indexes of 4 automobiles were normalized to eliminate the impacts of their dimensions and dimensional units. The comprehensive performances of the 4 automobiles were evaluated using method of improved radar chart which is characterized by the result uniqueness. The weights of the evaluated performances were anlyzed by the analytic hierarchy process to make the evaluated results more comprehensive and reasonable.
