A method for monitoring physiological status of a vehicle driver is performed by a monitoring device connected to a physiological sensor and comprises steps of: (a) establishing a personal physiological database comprising steps of: periodically sensing the vehicle driver via the physiological sensor to obtain the physiological signals within an initial duration; obtaining a mean value and a standard deviation based on the physiological signals; and obtaining a tolerance range based on the mean value and the standard deviation, such that the personal physiological database stores the tolerance range; (b) sensing the vehicle driver via the physiological sensor to obtain at least one instant physiological signal after the initial duration; and (c) determining whether the at least one instant physiological signal is out of the tolerance range, such that an alarm is outputted when the at least one instant physiological signal is out of the tolerance range.

A physiological signal processing method for filtering noise generated by a physiological signal processing system is performed by a physiological signal processing system having a sensing device and a filtering device in connection with the sensing device. The method comprises steps of synchronously receiving a physiological signal and a vibrational signal detected by the sensing device, performing a noise determination algorithm to acquire information in multiple time periods with noises occurring in corresponding time periods according to the vibrational signal, performing a physiological signal filtering algorithm to filter the noises in corresponding time periods of the physiological signal and compensate the filtered physiological signal, and estimating a physiological parameter according to a result of the signal compensation to generate the physiological parameter with accuracy.

The present invention discloses a driver's fatigue detection system and method. The system comprises a vital sign detection device generating at least one personal vital sign value; a storage device storing a linear statistic equation; a processor electrically connected with the vital sign detection device and the storage device; and a display device electrically connected with the processor. The processor receives the personal vital sign value, retrieves the linear statistic equation, substitutes the personal vital sign value into the linear statistic equation to generate a predictive vehicle deviation value, and determines whether the predictive vehicle deviation value is over a preset vehicle deviation value. If yes, the processor generates an alert signal to the display device to present an alert image. The present invention determines whether the stability of the driver is decreasing according to his physiological status and reminds the driver to avoid a traffic accident beforehand.
