Abstract
An ECU executes the step Sof detecting an intake air amount QA and an ignition timing IT, the step Sof calculating an estimated engine torque TE from QA and IT, the step Sof detecting the engine rotation speed NE and the turbine rotation speed NT, the step Sof calculating the speed ratio E of the torque converterthe step Sof calculating a torque capacity C from the speed ratio, the step Sof calculating a reference torque TP() from the torque capacity C, the step Scorrecting the reference torque TP() into TP based on a map, the step Ssetting TE as the estimated engine torque if TP is greater than TE, and the step Ssetting TP as the estimated engine torque if TP is not greater than TE.
