ABSTRACT:
An electronic control apparatus for an internal combustion engine having engine parameter data sensors, an input/output unit, actuators and a data processing unit carries out a prescribed scenario for starting the engine. The starting sequence begins with the operation of a starting subsystem having a switch the state of which controls the operation of the starter motor. The starter motor is caused to be engaged and a set of initialization procedures are carried out by the data processing unit and input/output unit in dependence upon the state of the switch in the starting subsystem. These initializing procedures include engine operation control calculations as well as system preset steps. During this time, prescribed interrupts which would otherwise be delivered to the data processing unit from the input/output unit are inhibited. However, once the engine has been started, the interrupt inhibit is removed and the system operates under normal conditions.
