DRIVER MONITORING DEVICE, DRIVER MONITORING SYSTEM AND DRIVER MONITORING METHOD

摘要

The purpose of the present invention is to provide a driver monitoring device which outputs a determination result about whether or not a warning was effective for the driver. This driver monitoring device controls a warning device so as to output a warning to the driver of a vehicle on the basis of the state of the driver. The driver monitoring device includes a driver state detection unit, a warning effect determination unit and a warning information output unit. The driver state detection unit detects the state of the driver. The warning effect determination unit determines whether or not the warning outputted from the warning device on the basis of the driver's state was effective for the driver on the basis of change in the driver's state before and after the warning or change in the driver's driving operation of the vehicle after the warning. The warning information output unit outputs the determination result from the warning effect determination unit. On the basis of the determination result, warnings to the driver are changed to another warning different from the warning already outputted.
