Vehicle drive force control device

摘要

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 (100), a target torque tTe of an engine (101) 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 (101) is the target torque tTe. At the same time, the target input shaft rotation speed tNin of the IVT (100) 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.
