ABSTRACT:
A system and method for controlling an engine idling speed for an internal combustion engine associated with an electro-continuously variable transmission are disclosed in which when an accelerator pedal is released to carry out an abrupt deceleration of the vehicle during the vehicle run with the transmission gear ratio in a second, third, or overdrive range, an engine fuel is instantaneously supplied in an asynchronous fuel injection mode so that the engine idling speed is temporarily increased and an oil pump revolution speed for changing the gear ratio is increased.
