Comprehensive evaluation method of offroad capability of special electric vehicles

According to the relevant test standards and the characteristics of special electric vehicles, the first-level evaluation indexes are set up as power, trafficability, mass geometric parameters and electric drive parameters, and the second-level indexes are determined based on typical driving conditions. The usability of trafficability index is analyzed, the weights of primary index and secondary index are determined by AHP and CRITIC respectively, and the comprehensive weights are determined by the combination of qualitative analysis and quantitative analysis. The correlation degree of vehicle index is calculated by grey correlation theory, and the vehicle evaluation result is determined by comprehensive weight. A comprehensive evaluation method for off-road capability of special electric vehicles is established by combining subjective and objective methods.
