ENGINE OUTPUT TORQUE MONITOR DEVICE, VEHICLE CONTROL DEVICE, AND ENGINE OUTPUT TORQUE MONITOR METHOD

摘要

PROBLEM TO BE SOLVED: To improve output torque estimation accuracy, when output torque of an engine is in the vicinity of zero.;SOLUTION: An engine output torque monitor device of the present invention comprises: an output torque calculating part 50 calculating an output torque estimation value of the engine by using indices indicating an engine operational statuses; a correction amount calculation part 52 calculating an output torque correction amount from the output torque estimation value calculated with a state where the engine output torque is estimated to be zero; and an output torque correction calculation part 54 correcting the output torque estimation value, which is calculated by the output torque calculation part, by using the output torque correction amount.;COPYRIGHT: (C)2008,JPO&INPIT
