PROBLEM TO BE SOLVED: To provide a method for more accurately determining a torque transmitted via a torque transmission path formed along a shaft of a vehicle. SOLUTION: A rotary position signal is produced by a first rotation speed sensor 18 at a first section of the torque transmission path 10, and a rotary position signal is produced by a second rotation speed sensor 20 at a second section of the torque transmission path. At a point in time when a known torque is transmitted along the torque transmission path, a first rotary position signal relevant information is determined by referring to the instantaneously generated rotational position signals. The determined first rotary position signal relevant information serves as an offset value. Subsequently, second rotary position signal relevant information is determined by referring to the instantaneously generated rotary position signals. Transmission torque is calculated based on at least the offset value and the second rotary position signal relevant information. COPYRIGHT: (C)2008,JPO&INPIT
