  • Torque sensing system having torque sensor, method for determining an amount of torque, and steering system
    Patent number: 8347739
    Abstract: A torque sensing system, a torque sensor, a method for determining an amount of torque, and a steering system are provided. The method includes generating a first output signal utilizing a first plurality of piezo-electric transducers disposed between a first plurality of tooth portions of a first hub portion and a second plurality of tooth portions of a second hub portion when the first hub portion is rotated in a first direction relative to the second hub portion. The transducers are electrically coupled in series with one another. The method further includes filtering the first output signal to obtain a first filtered signal and amplifying the first filtered signal to obtain a first amplified signal. The method further includes determining a first torque value indicative of a first amount of torque applied to an input shaft based on the first amplified signal.
