Research on driving cycles of hybrid tracked vehicle based on principal component analysis

Due to the complex and changeable road conditions of tracked vehicle, there was not specific study of driving cycles of hybrid tracked vehicles at home and abroad. Based on the test data of the previous generation of hybrid tracked vehicle samples driving on all kinds of roads for about 1 000 km during the test, this paper selected the representative roads of tracked vehicles as the typical pavement for the construction of driving cycles and used the principal component analysis method to construct appropriate driving cycles with shorter time series. Finally, it verified the correctness and rationality of the developed driving cycles through simulation.
