Title:
INERTIAL SENSOR
Document Type and Number:
WIPO Patent Application WO/2012/124358
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a high precision inertial sensor having fewer delays. An inertial sensor (1) of the present invention has: an acceleration detection element (2) for detecting the acceleration of at least one axle of a vehicle; a first filter (6) for limiting an acceleration detection signal to a first band; a second filter (7) for limiting the acceleration detection signal to a second band; a vehicle control quantity calculator (8) for calculating a vehicle control quantity (GXC) based on the acceleration detection signal limited to the second band; and a sensor signal output unit (9) for outputting the acceleration detection signal limited to the first band and the vehicle control quantity.
