Vehicle engine shaft torque sensing procedure corrects micro mechanical magneto elastic coil torque sensor measurement with zero torque stored reference values

摘要

A vehicle engine shaft (1) torque sensing procedure has a micro mechanical magneto elastic coil torque sensor (4, 5) in the bearing (2) shell and subtracts (6) a stored angle (3) dependent zero torque reference signal from the measured value : Independent claims are included for a sensor unit using the procedures.
