Abstract
PURPOSE: To make it pissible to greatly reduce the data storage capacity of an engine controller having a searching unit which stores information on control characteristics concerning various kinds of input information necessary for controlling and seaches for the former information.
CONSTITUTION: The rotational frequency x of engine is entered into the controller through an RPM register. A reference fuel injection time y is determined from the rotational frequency x and a value obtained by A/D-converting the flow rate of air applied from an air flow sensor. These data are divided to m1 and m2. The interval between them is divided to 2n1m2 and 2n2m2. The digital values at the intersecions of the division points of the data and the values at the division points are stored. Division points, which sandwich input data, are dtermined. The figure numbers nli, n2j corresponding to the intervals Zn1i, Zn2i between the division points are detemined. The figures and displaced dipending on the fiure numbers to perform interpolation
