摘要： A heartbeat rate detection apparatus and method which can accurately detect a heartbeat of a driver by simultaneously detecting a heartbeat rate of the driver with an infrared sensor, and detecting a heartbeat rate of the driver from a potential difference due to pulsation between both hands with a potencial type heartbeat sensor, comparing the the heartbeat rate detected by the infrared type heartbeat sensor with the heartbeat rate detected by the potential type heartbeat sensor, and selects one as an effective heartbeat rate.

摘要： An apparatus and method for a driver of a vehicle in which a level of awareness of the driver is determined, and compared with a reference value to determine a decrease in awareness. A warning is generated when driver awareness is low. The driver responds by terminating the warning. The reference value of the awareness determination means is corrected according to a response time of the driver to the warning.
