Title:
CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2023/100294
Kind Code:
A1
Abstract:
A processor (CPU) of a control device (ECU 27) for an internal combustion engine sets, for each rotation speed of the internal combustion engine, at least one crank angle for transient state determination that indicates the timing for determining the transient state of the output value of a flow rate sensor 2 (B1205). The processor sets at least one transient state determination threshold on the basis of the output value of the flow rate sensor 2 (B1207). The processor compares the output value of the flow rate sensor 2 at the crank angle for transient state determination with the transient state determination threshold to determine whether the output value is in a transient state (B1208). When the output value is not in the transient state, the processor corrects the output value of the flow rate sensor 2 in accordance with the pulsation width of the output value of the flow rate sensor 2, and when the output value is in the transient state, the processor limits the correction of the output value of the flow rate sensor (B1210, B1211).
