PROBLEM TO BE SOLVED: To detect a driver's biological information using a non-contact sensor without being affected by a noise signal generated by the vibration of a vehicle.SOLUTION: A biological information detection device for a vehicle includes: a first non-contact detection unit having a first transmission part for transmitting an electromagnetic wave from a back side of an occupant, a first reception part for receiving the electromagnetic wave reflected from the occupant, and a first synthesis part for synthesizing the transmitted electromagnetic wave and the received electromagnetic wave; a second non-contact detection unit having a second transmission part for transmitting an electromagnetic wave to the occupant from a breast side, a second reception part for receiving the electromagnetic wave reflected from the occupant, and a second synthesis part for synthesizing the transmitted electromagnetic wave and the received electromagnetic wave; and a processing unit having an addition part for adding a signal output from the first non-contact detection unit and a signal output from the second non-contact detection unit, and a processing part for processing the added signals and acquiring information on the occupant's respiration frequency and heart rate.SELECTED DRAWING: Figure 1 |
