Abstract
Secure failure diagnosis of a brake switch is enabled with a simple configuration. Inconsistency detection is performed for output signals from two brake switchesandprovided such that an operation condition of a brake pedalmay be detected (S), and when inconsistency is detected, after a certain time has passed from the relevant detection point, inconsistency detection is newly performed for output signals from the two brake switchesand(S), and when inconsistency is detected again, a determination counter performs count of a predetermined incremental value, those operation being periodically repeated (S), and when a count value reaches a predetermined value α after the determination counter performs the count, the two brake switchesandare determined to be failed (Sand S).
