内燃機関の制御装置およびそれを搭載する車両
Document Type and Number:
Japanese Patent JP5668842
Kind Code:
B2
Abstract:
An ECU (300) for controlling an engine (160) counts the continued period of stopping the engine (160) in a low-temperature environment. The ECU (300) sets the idle rotational speed at a first idle rotational speed when the stopped period is below a predetermined threshold value, and at a second idle rotational speed higher than the first idle rotational speed when the stopped period exceeds the reference value. Accordingly, resonance at the driving force transmission system during idle operation can be prevented even in the case where a mount employed for attaching the engine (160) to the vehicle is hardened as a result of undergoing a low-temperature environment for a long period of time, and the resonant rotational speed of the driving force transmission system including the engine (160) varies.
