Analysis of hybrid transit bus performance test

This paper mainly discussed the performance test of the sample hybrid electrical bus on the dynamometer test bench for analyzing the driving ability and the fuel economy. And the fuel economy conversion method of the conventional bus was introduced according to the characteristics of the hybrid electrical vehicle (HEV). In addition, in order to further improve the performance of HEV, the new control strategy was presented on the basis of the primary control algorithm. Finally the bench tests were performed for the diverse drive cycles. The test results show that the hybrid bus can indeed save fuel considerably in diverse drive cycles compared with the similar conventional bus. In particular, in the Beijing city drive cycle the fuel can be saved 30% more than the conventional one, which fully shows the superiority of HEV.
