    摘要： An engine powertrain control device is configured to reduce data amounts of characteristics of a torque converter and realize torque estimation with high accuracy. A device detects or computes rotating speeds of input and output shafts of the torque converter. A device computes a ratio (speed ratio) between the rotating speed of the input shaft and the rotating speed of the output shaft of the torque converter. A device stores data of a pump capacity coefficient and torque ratio product of the torque converter and computes a value of the product corresponding to a value of the speed ratio computed above, and a device is provided for computing an output shaft torque of the torque converter by using the value of the computed product.
