Abstract
CO2 reduction is becoming one of the primary responsibilities for manufacturers. There is an urgent requirement to meet the conflicting demand of fuel economy and other vehicle performance. In order to meet the demand, the energy analysis of the whole vehicle for the optimization is becoming indispensable. In this study, multi-domain simulation using IEEE and IEC standardized Hardware Description Language was applied to the whole vehicle model and validated. The result was agreed to measured data. The accuracy of the fuel consumption was 1.1% errors for 3.5L V6 AT vehicle and 1.4% errors for Hybrid Vehicle at the LA#4 driving pattern. The multi-domain simulation is effective for discussing vehicle performance at planning stage. The simulation can be embedded real software. It is also effective as a SILS (Software In The Loop Simulation) for system control developing stsge.
