Abstract
PURPOSE: To promote the reliability of an engine on the basis of the reduction of cost, the improvement of transient response, and the reduction of troubles by generating a unit angle interruption on the basis of a unit angle signal of a crank shaft for computing control data thereon.
CONSTITUTION: A microcomputer 50 is provided with a hard or soft-formed onterruption signal generating means ISD to generate interruption signals IS1 and IS2 by the supply of a reference angle signal SS and a unit angle signal US, a computation means ALU to carry on interruption and other computations by the supply of the interruption signals IS1 and IS2, and a read-only memory ROM and a random access memory RAM with various computing procedures written in. An output circuit 60 receives a signal from the microcomputer 50 and supples on/off signals to various controlled apparatuses via signal lines 61W65.
