Vehicle shift quality evaluation is the basis of integrated control for shift quality. To overcome the shortcomings of traditional subjective evaluation method for vehicle shift quality, a new approach to shift quality subjective evaluation based on fuzzy logic and evidence theory is proposed in this paper.

To achieve the shift quality evaluation effectively, reasonably and timely, a new model to evaluate shift quality based on evidence theory and fuzzy neural network (FNN) is proposed in the paper. A method combining subjective evaluation and objective evaluation is adopted. Subjective evaluation provided by various drivers is aggregated by means of evidence(More)
Modern manual transmissions are equipped with synchronizer systems for better and more comfortable shifting performance. In this paper the typical structure of manual transmission assemble for heavy-duty vehicle is firstly introduced with emphasis on the power flow of 3<sup>rd</sup> gear. Then the components of the synchronizer are introduced and the(More)
