DIAGNOSTIC DEVICE AND DIAGNOSTIC METHOD

摘要

PROBLEM TO BE SOLVED: To improve the entire failure detection rate by performing failure detection without depending on an output of a processing part and performing failure detection of a comparing part for performing the failure detection without limiting execution timing.

SOLUTION: This diagnostic device is provided with the comparing part for detecting a failure of processing parts by comparing two pieces of output information output from duplicated two processing parts, a failure information injecting part for injecting pseudo failure information so that the comparing part may detect the processing parts have a failure into the comparing part, and a failure determination part for performing failure determination of the comparing part by using a detection result of the comparing part to which the pseudo failure information is injected.
