Abstract
A grip sensor includes: a plurality of capacitive detectors which are disposed in a grip of a steering wheel of a vehicle, and output values which vary according to whether a human body is in contact; and a controller which determines, at a preset timing, a reference value to be subtracted from the values output from the plurality of capacitive detectors, to determine whether the human body is in contact, wherein the controller identifies, from among values output from the plurality of capacitive detectors at the preset timing, one or more values each having an absolute value smaller than a first threshold, and determines, as the reference value, one of the one or more values identified or an average of the one or more values identified.
