<P>PROBLEM TO BE SOLVED: To provide an electronic control device that can detect an anomaly in an A/D converter and can also detect an anomaly in a reference voltage for A/D conversion. <P>SOLUTION: Main microcomputer anomaly determination means 14 checks whether or not a voltage value of Vcc based on digital data 11a from a main microcomputer A/D converter 11 is at least at a threshold 13a to make an anomaly determination for the main microcomputer A/D converter 11 and Vref. Sub microcomputer anomaly determination means 24 checks whether or not a voltage value of Vcc based on digital data 21a from a sub microcomputer A/D converter 21 is at least at a threshold 23a to make an anomaly determination for the sub microcomputer A/D converter 21 and Vref. Anomaly identification means 15 identifies an anomalous section by using the anomaly determination results of both main microcomputer anomaly determination means 14 and sub microcomputer anomaly determination means 24. <P>COPYRIGHT: (C)2012,JPO&INPIT |
