Document Type and Number:
WIPO Patent Application WO/2019/181293
Kind Code:
A1
Abstract:
Provided is an internal combustion engine control device that favorably ignites an air-fuel mixture to improve ignition performance and fuel performance. The internal combustion engine control device controls an internal combustion engine provided with an ignition coil and an ignition plug and is provided with: a target supply energy calculation unit that calculates an energy amount required to ignite an air-fuel mixture supplied to a combustion chamber of the internal combustion engine on the basis of an operation condition of the internal combustion engine or a physical quantity related to ignition of the ignition plug; a current waveform generation unit that generates, in accordance with the energy amount, current waveform data related to the waveform of a current supplied to the ignition plug; and a power control unit that controls power supplied to the ignition plug in accordance with the current waveform data.
