To improve the test and evaluation technology system for fuel cell buses and effectively ensure their widespread applications, a comprehensive performance evaluation method for the power train of fuel cell buses is proposed, which combines the combination weighting method and subjective scoring method. First, a comprehensive performance evaluation system for the powertrain of fuel cell buses is constructed, and the test methods for each index are given. Then, the analytic hierarchy process and coefficient of variation are used to determine the subjective and objective weights of evaluation indexes, and the combination weighting method based on the game theory is used to obtain the comprehensive weights. On this basis, the subjective scoring method is used to score the test results of vehicles to be evaluated. At last, the comprehensive scores are obtained by weighted calculation with the comprehensive weight, which are further rated. The calculation result of an example shows that the comprehensive weight combining the subjective and objective weights over-comes the limitation of calculating the weight by only one single method and makes the evaluation results more objective and accurate, thus verifying the scientific nature and rationality of the evaluation system and method.
