发明名称 A/D CONVERSION CONTROLLER FOR INTERNAL COMBUSTION ENGINE
摘要 <P>PROBLEM TO BE SOLVED: To provide an A/D conversion controller which reduces processing time required for A/D conversion in a controller that A/D-converts a plurality of analog signals. Ž<P>SOLUTION: A microcomputer containing a plurality of independent A/D converters having the same performance for A/D conversion time is configured to assign a plurality of analog signals to different A/D converters when the analog signals are simultaneously A/D converted at a certain timing, and simultaneously start the A/D converters, so that multiple signals are A/D converted in the time required for one A/D conversion operation, thereby reducing the processing time.
