APPARATUS FOR DETECTING BIO SIGNAL OF DRIVER

摘要

The present invention relates to an apparatus for detecting a bio signal of a driver which is capable of detecting a bio signal with high accuracy by measuring a bio signal of the driver and a noise using a plurality of electrodes mounted on a steering wheel of a vehicle and detecting a final bio signal by applying an empirical mode decomposition to a result obtained from filtering the bio signal of the driver with the noise. To this end, an apparatus for detecting a bio signal of a driver according to the present invention includes: a bio signal measuring unit mounted on a steering wheel of a vehicle and measuring a radiocardiogram of a driver; a noise measuring unit for measuring a movement noise; an adaptive filter for filtering the bio signal measured by the bio signal measuring unit on the basis of the movement noise measured by the noise measuring unit; a signal decomposition unit for decomposing a signal passing through the adaptive filter for each frequency; and a bio signal detecting unit for combining at least two signals from among signals decomposed by the signal decomposition unit to detect as a bio signal.
