Article Preview

An active differential is introduced with its basic structure and working principle, it consists of a couple of slip clutches for torque transfer and some planetary gears which generate the differential speeds of the slip clutches. A mathematical model of active differential dynamics is developed and it is used for a theoretical analysis of torque transfer and energy loss. Modeling and simulation of the active differential are carried out by using MATLAB/Simulink, the results demonstrate that active differential generates the direct yaw moment by torque transfer between right and left tires and is possible to improve the overall performance of vehicle dynamics properties.
