Modeling and simulation for the dynamic analysis of an electronically controlled torque coupling

Abstract Controllable AWD coupling systems are applied for optimizing vehicle traction capability and dynamic performance by adequately distributing the torque between the front and the rear axles according to the driving condition. With its linearity, compactness and low power consumption, JTEKT Intelligent Torque Controlled Coupling (ITCC) features a high performance to power consumption ratio. A 5-dof model of an ITCC is proposed for satisfying the requirements on further insight on the internal dynamics and the interaction with the vehicle driveline. The model is validated against experimental data followed by static and dynamic analyses. The results obtained justify the development of evolved coupling modeling for a better understanding of the internal motion of the coupling and the interaction with the driveline dynamics.
