CONTACT DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/095478
Kind Code:
A1
Abstract:
The plurality of openings (44) are disposed in the housing along the outer shape of the housing on a further outer side than the disposition region of the ultrasonic transducers (21) when viewed in a direction perpendicular to the main surface. A determination unit determines, by means of the contact detection circuit, whether an operator makes contact with the steering wheel, and determines, by means of the voltage decrease detection circuit, whether the operator is putting pressure on the steering wheel, and whether the operator grips the steering wheel. Accordingly, the operation detection device can appropriately detect the contact state of the operator with the steering wheel.
