摘要

PROBLEM TO BE SOLVED: To provide a control device capable of discriminating an abnormality a supply source of input data supplied to an ECU from a CPU incorporated in the ECU.

SOLUTION: A control device 100 includes: data output means 22 for outputting first data and outputting second data after the first data; data prediction means 16 for predicting the second data from the first data and outputting it as predicted data; first arithmetic operation means A for performing arithmetic operation on the second data; second arithmetic operation means B for performing arithmetic operation on the predicted data; and comparison means 17 for comparing between a fist output value on which the first arithmetic operation means has performed an arithmetic operation and a second output value on which the second arithmetic operation means has performed an arithmetic operation on the predicted data.
