Title:

ELECTROSTATIC CAPACITY SENSOR AND GRIP DETECTION DEVICE

Document Type and Number:

WIPO Patent Application WO/2015/119285

Kind Code:

A1

Abstract:

A grip detection device that comprises: an electrostatic capacity sensor (2) that is installed on a rim (11) of a steering wheel (1); and a determination unit (3) that detects gripping of the steering wheel on the basis of sensing results from the electrostatic capacity sensor (2). The electrostatic capacity sensor (2) is configured from a plurality of oblong electrode units (2a-2f) that are provided along the circumferential direction of the rim so as to be parallel and that extend along the direction in which the rim extends. Among the plurality of electrode units (2a-2f), at least two electrode units are commonly connected, and at least one electrode unit that is not commonly connected to the two commonly connected electrode units is arranged between the two commonly connected electrode units. The determination unit determines that a driver has gripped the steering wheel when contact by a human body is sensed by each of at least two electrode units that are not commonly connected to each other.
