VEHICLE AND ON-VEHICLE DRIVE DEVICE

Document Type and Number:

WIPO Patent Application WO/2008/062665

Kind Code:

A1

Abstract:

When a torque exceeding a predetermined value is outputted from a motor for a predetermined time while a vehicle is in the stop state while outputting a corresponding torque Tmr based on the accelerator open decree Acc, a torque instruction Tm2* is set so as to reduce the torque from the motor (MG2) by using a torque reduction ratio Rd2 set in accordance with the accelerator open degree Acc (initial accelerator open degree Acci) in the stop state and the corresponding torque Tmr (steps S370, S380). When the phase where the motor current is concentrated is switched (step S330), a torque instruction Tm2* is set so as to increase the torque from the motor (MG2) by using the torque increase ratio Ri set according to the accelerator open degree Acc in the stop state (steps S450, S460).
