ComparisononSec@on1



ComparisononSec@on2



1.  Possibility of virtual test driving tool applied for fuel consumption sensitive analysis was demonstrate.

2.  On suburban road, which is free from traffic condition, driving behavior has effect on the fuel consumption, and on highway, vehicle velocity has effect on the fuel consumption.

1.  It means that fundamentally character is estimated perfectly

3.  Difference of speed profile on virtual and real test driving causes a disagreement of validation in conparison between them.

4.  Modeling of traffic condition/profile is required for higher accurate simulation for RDE.
