ABSTRACT:
In an engine torque loss computing section, a pump loss computing section computes a pump torque loss, and a frictional loss computing section computes a frictional torque loss. The pump torque loss and the frictional torque loss are summed to obtain an engine torque loss. Furthermore, a torque loss correction amount computing section computes a torque loss correction amount, and a correction amount changing section changes the torque loss correction amount based on a result of determination of whether fuel cut-off is currently executed. The torque loss correction amount is added to the uncorrected initial engine torque loss to obtain a corrected engine torque loss.
