It is known that the shift processes of the four types of clutch-to-clutch shifts can theoretically be divided into two phases which are torque phase and inertia phase, but the execution orders are different. Two virtual clutch controllers are designed with the same eight states which include all control processes for these shifts. An equivalent method is proposed so that AT can be controlled just like DCT by adopting the torque ratios of oncoming clutch and offgoing clutch of each gear. The powertrain system model and the shift controller are established on Matlab/Simulink platform. The clutch-to-clutch shift processes have been studied based on the virtual clutch controller by software-in-the-loop simulations. Some typical problems in the clutch-to-clutch shift control are discussed and several control methods are compared to solve these problems.
At the request of the Publisher, the following articles have been retracted. The Advances in Mechanical Engineering Editorial Office became aware that the peer review process organised by the Guest Editors of the Special Collections Advanced Control and Analysis of Mechatronics Systems with Modelling Uncertainty and Advanced Control of Robotics and Mechatronics Systems with Nonlinearity and Modelling Uncertainty 2016 did not meet the journal's usual rigorous standards of peer review. Due to this, all articles in these Special Collections were re-reviewed by a new set of independent referees.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
