ABSTRACT:
During a standstill, a prescribed rotation speed N3, which is lower than a prescribed rotation speed N2used during a travel at a low vehicle speed, is set as a minimum rotation speed Nemin (S410), and when a demand for an idle operation has been made (S490), the minimum rotation speed Nemin is set as a target rotation speed Ne* and the value 0 is set as a target torque Te* (S500), whereby an engine is controlled. As a result of this, it is possible to improve the fuel consumption of a vehicle when the engine is operated at idle at standstill compared to a case where the engine is operated at idle at the minimum rotation speed Nemin for which the prescribed rotation speed N2is set regardless of whether or not the vehicle is at a standstill.
