This paper presents a systematic model for the simulation and analysis of a power-shift transmission that features a dual-clutch design. The paper models the kinematics, dynamics, and control of the transmission for the analysis of powertrain overall performance and shift transient characteristics. The model is implemented in an object-oriented software tool. Analytical formulations and look-up tables are both used for modeling of powertrain components. The vehicle system model is established by integrating the various components and subsystem models according to the transmission power flow and control logic. The input to the simulation model is the vehicle speed-time profile and the output provides the speed follow-up, engine, and clutch operation status for the drive range and shift processes involved. As a numerical example, the model is used for a vehicle equipped with the power-shift transmission to simulate the speed follow-up over a specified drive range and the dynamic transients during shifts.© 2004 American Institute of Physics.
