Abstract: Global transport application (GTA) is a common expression to define transport missions for development, sales and aftermarket processes. To achieve a light weight and low-cost powershifting transmission for the targeted heavy vehicle applications, GTA was used in the development of the I-Shift Dual Clutch (I-Shift DC). Using a well-defined transport mission enables relevant modelling and simulation for performance assessment. This paper outlines the methods and shows some examples of technical implications. Firstly, the results from real world measurements in one specific scenario are presented. This shows the difference between a single clutch (SC) and dual clutch (DC) transmission for heavy-duty vehicles. Secondly, a full vehicle simulation model is built to extend the results to longer transport missions. The measurement results are used to parametrise and calibrate the model. Finally, the calibrated model is used to evaluate the performance in detail by using GTA to select appropriate transport missions for simulation.
