Practical application of Optimization Technique to model-based vehicle development

This proceeding presents the design of thermal system strategy at the early stage of vehicle development where a practical simulation approach is investigated. The simulation is characterized by optimization technique for sensitivity analysis and model identification. By identifying four parameters, the thermal model could express complicated powertrain warm-up behavior. The simulation can predict heat flow from heat source to heat sink relating to the powertrain, as well as fluid temperature and fuel consumption.
