METHOD AND APPARATUS TO DETERMINE TORQUE IN A POWERTRAIN SYSTEM |
摘要 |
A method for monitoring torque in a gear train includes coincidentally determining angles of rotation of first and second rotationally coupled members of the gear train. Each of the members employs a respective rotational position sensor. Each of said angles of rotation are determined based upon times corresponding to a last signal pulse, a next-to-last signal pulse, and a total quantity of signal pulses generated by the respective rotational position sensor during a current sampling interval. A twist angle corresponding to a difference between the angles of rotation of the first and second rotationally coupled members of the gear train is determined, and torque corresponding to the twist angle is calculated.
