Abstract
A method for engine control under an entire driving range of a vehicle based on control timing prediction implemented in the vehicle is provided, which may reduce a start angle error calculated at a calculation time prior to an operation time when actual injection and ignition is performed by grasping a tooth period change tendency for a tooth period of a current time that injector/igniter drivers of an engine control unit read from an engine position management driver and calculating a start angle of fuel injection and ignition through prediction of the tooth period to match an actual operation time. In particular, since the prediction of the tooth period to match the actual operation time is based on a change tendency of the tooth period stored up to the current time, the injection and ignition time effectively reflects an engine operation situation in which an engine RPM is changed.
