전자식 4WD 성능평가 TOOL 개발

Sports Utility Vehicle (SUV) is growing in popularity in these days. Four wheel drive (4WD) system on SUVs require optimal torque distribution to improve powerful traction as well as handling stability. In the same time, driveline NVH and durability must be considered. In order to satisfy this requirement, optimal torque control strategy researched and proved by developing analytical measuring tool. This paper also shows various case studies with data analysis concerned with 4WD development issue. By using 4WD performance analysis tool, test and tuning was carried out efficiently as well as quickly.
