Abstract
An object of the invention is to provide an inertial sensor with small delay and high accuracy. An inertial sensorincludes an acceleration detecting elementthat detects an acceleration of at least one axis of a vehicle; a first filterthat limits a detection signal of the acceleration to a first band; a second filterthat limits a detection signal of the acceleration to a second band; a vehicle control variable calculation sectionthat calculates a vehicle control variable Gon the basis of the detection signal of the acceleration limited to the second band; and a sensor signal output sectionthat outputs the detection signal of the acceleration limited to the first band and the vehicle control variable.
