Abstract
PURPOSE: To attain a high controllability of an electronic engine controlling apparatus comprising a central processing unit for processing digital operation, independently of changes in the operational condition of engine, by dividing the engine controlling content into several tasks, and determining the task starting period according to the influence to engine controllability exerted by the processing function.
CONSTITUTION: When CPU102 is started, initializing program 204, monitoring program 206 and background job 208 are exected. As the background job 208 for example, taks like calculation of the exhaust gas recirculating rate are performed. When an interruption factor IRQ is produced during execution of the task, IRQ- factor analyzing program 224 is executed. This program is composed of program 226 for processing interruption by completion of ADC1, program 228 for processing interruption by completion of ADC2, program 230 for processing interruption by passing of a prescribed time period, program 232 for processing interruption by engine stop, etc., and gives start demands to respective tasks required for starting the tasks.
