GRIPPING-DETECTION DEVICE

摘要

A gripping-detection device includes a first electrode and a second electrode provided on a steering wheel of a vehicle; a heartbeat detection unit that detects the heartbeat of a driver that is in contact with the first electrode and the second electrode based on a voltage pattern obtained from the first electrode and the second electrode; a first sensor and a second sensor that detect an electrostatic capacitance in the steering wheel; and a gripping state determination unit that determines a gripping state of the steering wheel of the driver based on the electrostatic capacitance detected by the electrostatic capacitance detection unit and a voltage pattern of the first electrode and the second electrode detected by the heartbeat detection unit.

1. A gripping-detection device comprising:
a pair of electrodes provided to a steering wheel of a vehicle, each of the pair of electrodes being arranged on the steering wheel to be in contact with one of driver's hands; a heartbeat detection unit that detects a heartbeat of a driver that is in contact with the pair of electrodes based on a voltage pattern obtained from the pair of electrodes; an electrostatic capacitance detection unit that is provided to the steering wheel in a vicinity of the pair of electrodes to detect an electrostatic capacitance; and a gripping state determination unit configured to determine a gripping state of the driver's hands with respect to the steering wheel based on the electrostatic capacitance detected by the electrostatic capacitance detection unit and a voltage pattern of the pair of electrodes detected by the heartbeat detection unit.
