VEHICLE DRIVE DEVICE AND VEHICLE DRIVE METHOD

摘要

When an accelerator pedal of a vehicle which is being driven is released from being pressed down, an automatic transmission device is up-shifted. Based on the engine RPM and the transmission ratios of the automatic transmission before the up-shift and the automatic transmission after the up-shift, a prediction is made of the engine RPM immediately after the up-shift of the automatic transmission. If it is predicted that fuel recovery will be carried out immediately after the up-shift, the fuel recovery is carried out in the inertia phase of the automatic transmission.
