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 structure and control logic. 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 standard EPA drive range and the wide open throttle position performance.
