Driver abnormality sign detection method and device are provided that are capable of detecting an abnormality sign of a driver while realizing both of high responsiveness and high reliability.A driver abnormality sign detection method includes a step B of estimating a heartbeat interval BI of a driver based on heartbeats detected by a driver camera, a step C of acquiring time-series data of the heartbeat interval of the driver in a predetermined time period, a step D of standardizing the time-series data of the heartbeat interval, a step E of calculating a probability PA that the standardized heartbeat interval falls within a predetermined range (A region), which has zero as a center, in the time-series data of the standardized heartbeat interval CG-Blz, and a step F of determining that a sign of an abnormality of the driver is detected in a case where the probability PA is greater than a predetermined abnormality sign threshold value TA.
