Abstract:
The main aim of researchers, to prevent the spinning and drifting of vehicle, is to monitor the yaw stability control strategy. The yaw stability control system is incorporated with active torque distribution. A lot of work is done on torque distribution between right and left wheels using active differential to distribute torque to each drive wheel. Control algorithm based on different control strategies were used for torque distribution. In this study, active torque distribution strategy is incorporated via central transfer case between front and rear axle. A 4WD vehicle is used with 50-50 torque ratio amongst front and rear axle. The controlling parameter is the understeer and oversteer behavior of the vehicle. A combined slip model approach used by Burckhardt is used for a 10 DOF vehicle modeling using MATLAB. The simulated results will be compared against a multibody nonlinear simulation software i.e. CarSim. For implementation, J-turn test and Double Lane Change (DLC) were used.
