Abstract

A method for diagnosing a failure in a sensor module includes: a first diagnosis step of diagnosing that when a comparison result between a first angular velocity based on an output signal of a first sensor element detecting an angular velocity around a first axis and a second angular velocity based on an output signal of a second sensor element detecting an angular velocity around the first axis satisfies a first standard, the first sensor element and the second sensor element are normal; and a second diagnosis step of performing failure diagnosis of the first sensor element using the first angular velocity signal or the second angular velocity signal and an acceleration signal based on an output signal of a third sensor element detecting an acceleration in a second-axis direction when the comparison result does not satisfy the first standard.
