Title: Torque detecting apparatus
Inventor: MUNETOU TAKASHIGE
IPC: G01L3/10
Filed: 1991-09-30
Abstract: PURPOSE:To detect a torque highly accurately in a low output region by changing the output characteristics of a torque detecting apparatus in response to the output of an engine. CONSTITUTION:The voltage of a torque signal is determined based on a correlation line B when the output of an engine is in a low-output region and based on a correlation line A when the engine output exceeds the low-output region. The voltage is outputted into a line-voltage adjusting means 10 of an automatic change gear with an output-characteristic selecting means 8 of a torque detecting apparatus. When the engine output is low and a turbine-shaft torque (a) is a low value Ts, the torque signal voltage (b) based on the correlation line A is outputted into the means 10. When an error of V is generated in the output voltage by some cause and the detected torque error  TA is generated, a large error is generated in the adjustment of the line voltage. On the contrary, when the torque signal voltage based on the correlation line B is outputted into the line-voltage adjusting means as the output of the detector torque signal, the detected torque error for the error  V of the output voltage becomes  TB. Thus, the detecting accuracy of the torque detecting apparatus in the low-output region of the engine is enhanced.
