Abstract
A target output shaft torque tTo is computed based on an accelerator pedal depression amount APS and a vehicle speed VSP, a torque ratio T is computed based on an input shaft rotation speed and a speed ratio factor E of a IVT ( ), a target torque tTe of an engine ( ) is computed from the target out shaft torque tTo and torque ratio T, and control is performed so that the torque generated by the engine ( ) is the target torque tTe. At the same time, the target input shaft rotation speed tNin of the IVT ( ) is calculated based on a vehicle running state, and control is performed so that the input shaft rotation speed Nin and target input shaft rotation speed tNin of the IVT coincide.
