<P>PROBLEM TO BE SOLVED: To eliminate shock resulted from fuel recovery during pedal release and up-shift in the vehicle. <P>SOLUTION: When an accelerator pedal of the vehicle which is being driven is released from being pressed down, an automatic transmission device is up-shifted. Based on the engine rotation speed and the transmission ratios of the automatic transmission before the up-shift and after the up-shift, a prediction is made of the engine rotation speed 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. <P>COPYRIGHT: (C)2013,JPO&INPIT |
