Abstract
An inertia detection device includes one set of gyro sensors for detecting an angular velocity of a detection target object along a same direction, the gyro sensors arranged in a same physical quantity range, in which sensor movement is detectable as a same physical quantity. When an abnormality affecting an output signal of one of the gyro sensors is caused, based on an observation that a difference of magnitudes of the output signals from normal and abnormal gyro sensors is different from a difference of magnitudes of the output signals from two normal gyro sensors, such an abnormality of one of the gyro sensors is determinable by a comparison between the output signals, without using an estimated value thereof.
