VERIFICATION DEVICE OF VEHICLE CONTROLLER

摘要

PROBLEM TO BE SOLVED: To provide a verification device which is capable of correctly verifying many models of vehicle controllers different in a fault diagnosis threshold by correcting a verification pattern (a test pattern).SOLUTION: It is determined whether a prescribed test pattern for diagnosis read from an HILS body satisfies a condition or not. If it does not satisfy the condition, a test pattern of a diagnosis section (a correction section) is corrected on the basis of a fault diagnosis threshold (a ROM value) read from an ECU (a vehicle controller), and the corrected test pattern is used to verify whether a diagnostic function of the ECU is correct or not.
