Abstract
Various sensor signals of an engine are A/D-converted by an A/D converter of a sub-microcomputer by an A/D conversion request from a main microcomputer. The A/D conversion is executed a plurality of times within one packet for important parameters in the various sensor signals in the A/D conversion request timing per constant time with a longer time interval than a time required for the A/D conversion by an A/D conversion request timing asynchronous to the A/D conversion request. Thereby, normal ones among a plurality of A/D-converted values A/D-converted by the A/D conversion request of the main microcomputer even if the preceding A/D conversion request is issued asynchronously to the A/D conversion request of the main microcomputer.
