Abstract
In a bio-information detecting apparatus, whether detection of heartbeats by a steering wheel sensor is possible is judged. When it is judged that the detection by the steering wheel sensor is impossible, whether detection of heartbeats by an installed-in-seat sensor is possible is judged. In this judgment, a judgment based on an output from an acceleration sensor and a judgment based on a heart-rate fluctuation range obtained from an output from the steering wheel sensor are executed.

17. A bio-information detecting apparatus that is installed in a moving object operated by an operator, and that detects bio-information on a mental and physical state of the operator, the bio-information detecting apparatus comprising:
-
a first sensor that includes at least a pair of electrodes and that detects a first heartbeat based on potential difference between potential values measured at portions of a body of the operator that directly contact the electrodes; and
a second sensor that detects a second heartbeat by detecting vibration of a surface of the body, the vibration associated with a heartbeat, wherein the bio-information detecting apparatus judges, when the first sensor is impossible to detect the first heartbeat, whether the second heartbeat is reliable. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A bio-information detecting apparatus that is installed in a moving object operated by an operator, and that detects bio-information on a mental and physical state of the operator, the bio-information detecting apparatus comprising:
-
a first sensor that includes at least a pair of electrodes and that detects a first breath rate based on potential difference between potential values measured at portions of a body of the operator that directly contact the electrodes; and
a second sensor or an image sensor that detects a second breath rate by detecting vibration of a surface of the body, the vibration associated with breathing, wherein the bio-information detecting apparatus judges, when the first sensor is impossible to detect the first breath rate, whether the second breath rate is reliable. - View Dependent Claims (32)
