Abstract:
1. An inertial sensor comprising: an acceleration detecting element that detects a longitudinal acceleration of a vehicle and a lateral acceleration of the vehicle; a first filter that limits a detection signal of the longitudinal acceleration and a detection signal of the lateral acceleration to a first band; a second filter that limits the detection signal of the lateral acceleration to a second band that has a higher cut-off frequency than the first band; a vehicle control variable calculation section that calculates a vehicle control variable of the vehicle on the basis of the detection signal of the lateral acceleration limited to the second band by the second filter and a lateral jerk that is a differential value of the lateral acceleration; and a sensor signal output section that outputs the detection signal of the longitudinal acceleration and the detection signal of the lateral acceleration to an electronic control unit, both outputted detection signals being limited to the first band by the first filter, and outputs the vehicle control variable calculated by the vehicle control variable calculation section to the electronic control unit.
