AI Technical Summary
Technical Problem
Existing driver heartbeat signal measurement devices can only detect heart rate and lack the capability to detect a driver's sweating state.
Method used
A steering wheel detection device equipped with first heart rate detection, first sweat detection, and reference electrodes positioned on the rim of the steering wheel, along with heart rate and sweat detection circuits, allows for simultaneous detection of heart rate and sweating state.
Benefits of technology
The device effectively detects both heart rate and sweating state of the driver, enabling estimation of driver emotions and facilitating adaptive vehicle systems based on these biometric inputs.

Abstract
The present invention provides a steering wheel detection device capable of detecting the driver's heart rate and sweating status. [Solution] The steering wheel detection device 3 comprises a first heart rate detection electrode 11, a first sweat detection electrode 12, a first heart rate and sweat detection combined electrode 13, and a reference electrode 14, all positioned on the rim 20 of the steering wheel 2. The first heart rate detection electrode 11 is positioned on the right or left side of the rim 20, the first heart rate and sweat detection combined electrode 13 is positioned on the left or right side of the rim 20 opposite to the first heart rate detection electrode 11, the first sweat detection electrode 12 is positioned adjacent to the first heart rate and sweat detection combined electrode 13 so as not to come into contact with it, and the reference electrode 14 is positioned on at least one of the right and left sides of the rim 20, and is positioned so as not to come into contact with the first heart rate detection electrode 11, the first sweat detection electrode 12, and the first heart rate and sweat detection combined electrode 13.
