    摘要： In an idling-stop cancellation control apparatus of a vehicle driving system of an idling-stop control device equipped 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, a controller is configured to execute, based on engine speed, idling-stop cancellation control by which the vehicle driving system is put into an output torque state suited for vehicle-driving operation, when a hydraulic pressure sensor system provided for detecting a hydraulic pressure used for shift control of the transmission is failed. The controller is further configured to execute, based on the hydraulic pressure, idling-stop cancellation control by which the vehicle driving system is put into an output torque state suited for vehicle-driving operation, when the hydraulic pressure sensor system is unfailed.

    摘要： A continuously variable transmission includes a variator (20) capable of varying a speed ratio continuously, and a subtransmission mechanism (30) provided in series with the variator (20). When an actual through speed ratio passes a predetermined mode switch speed ratio, a transmission controller (12) performs a coordinated shift in which a gear position of the subtransmission mechanism (30) is changed and a speed ratio of the variator (20) is varied in an opposite direction to a speed ratio variation direction of the subtransmission mechanism (30). When the rapid deceleration is determined to be underway, the transmission controller (12) decreases a speed ratio variation amount of the variator (20) in the direction of a High side accompanied by a downshift of the subtransmission mechanism (30) compared with the coordinated shift.
