Abstract
A magnetic torque sensing device having a torque transferring member with a magnetoelastically active region. The magnetoelastically active region has oppositely polarized magnetically conditioned regions with initial directions of magnetization that are perpendicular to the sensitive directions of magnetic field sensor pairs placed proximate to the magnetically active region. Magnetic field sensors are specially positioned in relation to the torque-transferring member to accurately measure torque while providing improved RSU performance and reducing the detrimental effects of compassing. The torque sensing devices are incorporated on vehicle drive train components, including differential components, transfer case components, transmission components, and others, including on power transmission shafts, half-shafts, and wheels, and output signals representing characteristics of the vehicle are processed in algorithms to provide useful output information for controlling actions of the vehicle.
