Abstract:
1. An idling-stop cancellation control apparatus of a vehicle driving system of an automotive vehicle capable of running by a power produced by an engine and transmitted via a transmission whose shift is controlled by a hydraulic pressure produced by an engine-driven oil pump during operation of the engine, comprising: a hydraulic pressure sensor provided for detecting a hydraulic pressure used for shift control of the transmission; and an idling-stop control device configured to execute idling-stop operation by which the engine is automatically stopped when a predetermined condition is satisfied under a state where a stop of the vehicle has been decided, and also configured to inhibit the idling-stop operation to restart the engine when the predetermined condition becomes unsatisfied, the idling-stop control device comprising: a normal idling-stop cancellation control section configured to execute idling-stop cancellation control by which the vehicle driving system is put into a state suited for vehicle-driving operation, when a detected value of the hydraulic pressure sensor becomes greater than or equal to a predetermined pressure value; and an emergency idling-stop cancellation control section configured to execute idling-stop cancellation control of the vehicle driving system regardless of the detected value of the hydraulic pressure sensor, when a speed of the engine becomes greater than or equal to a first engine-speed threshold value.
