Dry dual clutches are widely used in automotive transmissions because of its reliability and efficiency in energy transmission with low fuel consumption and reduction of pollutant emissions.A prerequisite to attain these goals is the adoption of a good clutch model and the design of a robust control strategy.In this paper,based on the literatures at home and abroad,the development status and technical difficulties of clutch modeling and control strategies are summarized.The dual-clutch transmission(DCT)actuator architectures as well as the start and shift dynamics models are analyzed.The start and shift control strategies and methods for DCT at home and abroad are explored,and the advantages and disadvantages of different control methods are compared.Finally,some topics of interest for future research are presented.
