SYSTEM AND METHOD FOR MEASURING TORQUE AND SPEED OF AN AXLE

Methods and systems for estimating an amount of torque that is transferred via a differential ring gear assembly are described. In one example, axial displacement of the differential ring gear assembly is determined and converted into a torque estimate. The torque estimate may be used to verify othe...

More Information
Summary:Methods and systems for estimating an amount of torque that is transferred via a differential ring gear assembly are described. In one example, axial displacement of the differential ring gear assembly is determined and converted into a torque estimate. The torque estimate may be used to verify other powertrain torque estimates or for closed loop torque control.
