Title:
INTERNAL COMBUSTION ENGINE CONTROL DEVICE, AND METHOD FOR CONTROLLING INTERNAL COMBUSTION ENGINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/167903
Kind Code:
A1
Abstract:
An internal combustion engine control device that calculates multiple ignition timings, and that includes: an ignition timing setting unit, which sets multiple estimated ignition timings which are retarded by a knock feedback amount that corresponds individually to each set ignition timing; and an ignition control unit, which performs ignition at the most retarded ignition timing, of the multiple estimated ignition timings. When knocking occurs, the internal combustion engine control device updates the knock feedback amount corresponding to the set ignition timing having the most retarded angle, among the knock feedback amounts corresponding individually to each set ignition timing, so as to be more to the retarded side, and maintains the other knock feedback amounts at their previous values. Furthermore, when knocking does not occur the internal combustion engine control device updates the knock feedback amount corresponding to the estimated ignition timing having the most retarded angle, among the knock feedback amounts corresponding individually to each set ignition timing, so as to be more to the advanced side, and maintains the other knock feedback amounts at their previous values.
