Title:
INTERNAL COMBUSTION ENGINE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2018172994
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To further reduce processing load in controlling an internal combustion engine while maintaining determination accuracy for occurrence of anomaly of the internal combustion engine.SOLUTION: In an internal combustion engine control device 10, a sampling interval change part 36 calculates a cylinder internal pressure rising rate DP based on cylinder internal pressure Pi and a crank angle CA and, when the calculated cylinder internal pressure rising rate DP goes out from a predetermined pressure change rate range (AL≤DP≤AH) in a range of the predetermined crank angle CA, shortens a sampling interval for a cylinder internal pressure signal at a sampling part 34.SELECTED DRAWING: Figure 1
