To detect the phase difference period After the gear and the phase difference period of the light source passing through the gear are detected by the optical sensor, the operating torque value converted into an electrical signal at the input processing interface of the TCU is calculated as a relative torque value which is calculated by comparing with the initial torque value. Torque measuring device of automatic transmission vehicle and torque using the TCU which executes the hydraulic control valve, shift control valve A and B, and damper clutch control valve by comparing the safety limit torque value and commanding accurate torque control. The invention relates to a measuring method.
