4륜구동 차량의 구동토크 배분이 조종 안정성에 미치는 영향

This paper presents a vehicle dynamics model with detailed drive train model to analyse handling performance of 4WD Vehicle vehicle with varying torque distribution. The functional suspension model was used to derive a full vehicle dynamics model with kinematic and compliance characteristics of suspensions. The drive train is modeled with front, rear and center differential gears and soft flexibility. A wheel dynamics model with tire relaxation effects was used for more realistic simulation. Several simulation results of 4WD vehicles demonstrate the effectiveness of current model to evaluate torque distribution effects on handling performance.
