A Review of Research on Start-up Judder of Vehicles

Abstract:

This paper discussed the research status and development trend of the dynamical problem of start-up judder of vehicles. First， the transmission system model of vehicles was used as a simulation platform to reproduce the problem， which focuses on the components closely related to the start-up conditions， including clutch operating characteristics， friction characteristics， and engine models. Then， in view of the start-up judder， the research contents and methods of start-up judder mechanics were discussed from the perspective of experimental research， generation mechanism， and suppression measures. Finally， based on the existing research results and their deficiencies， the focuses and difficulties of the research on start-up judder were pointed out， which provides references and suggestions for further research.
