INTERNAL COMBUSTION ENGINE CONTROL DEVICE

The problem addressed by the present invention is to prevent the occurrence of engine stoppage even during a shifting operation in an internal combustion engine control device that is a so-called cooperative control device automatically controlling the internal combustion engine and a transmission, and that performs feedback control of the rotational frequency of the internal combustion engine with respect to the idling rotational frequency and when the vehicle is performing creep travel. The control device (5) is provided with a control means (6) that alters the lower limit value for the amount of feedback control in accordance with the engagement state of a clutch (3).
