Active driveline torque-management systems

This article reviews various individual wheel torque control technologies for active automotive safety systems. The use of active drive torque-management for vehicle stability control is a relatively new technology that is still being developed by researchers and automotive manufacturers. Current approaches and effects in various types of devices and drivelines were discussed. Control strategies for cornering performance and vehicle yaw and roll stability related to active torque-management systems were investigated. Three major types of ADTM devices, namely, center couplings, ELSDs, and torque-vectoring systems, were described, and the models, control system design, and limitations of each were discussed.
