4WD의 최적 토크 분배 비 계산

Abstract

A transfer case is a main device of 4WD. It must optimally distribute torque to front wheels and rear wheels according to various driving conditions to reduce tire slip. Optimally distributing torque between front and rear wheel is very important to improve driving performance. This research shows that basic torque distribution ratio depends on mass center. We designed a transfer case controller considering mass center and longitudinal acceleration, which shows good driving performance at accelerated cornering.
