ABSTRACT |
This paper presents the vehicle handling performance improvement by means of transfer case and torque vectoring system. The focus is on the agility and stability during handling situation. Transfer case can control the torque distribution ratio between the front and rear axles. The left and right torque vectoring system of the rear axle is a device that can control both the torque flow amount and its direction between the right and left wheels. The controller for lateral dynamics was applied by using a sliding mode control method and a commercial dynamic analysis tool was used for the vehicle performance simulation. |
