Abstract:
1. An on-board warning apparatus comprising: an inattentive time measuring device that measures a duration of an inattentive state of a driver; a dozing time measuring device that measures a duration of a dozing state of the driver; a first warning output device that warns the driver when the measured inattentive time exceeds a first predetermined period of time; and a second warning output device that warns the driver when the measured dozing time exceeds a second predetermined period of time, wherein the first predetermined time is shorter than the second predetermined period of time, and wherein the on-board warning device is configured such that the duration of the inattentive state from the time when the inattentive time measuring device starts to detect the inattentive state until the first warning output device starts to warn the driver by outputting an inattentive warning is shorter than the duration of the dozing state from the time when the dozing time measuring device starts to detect the dozing state until the second warning output device starts to warn the driver by outputting a dozing warning.
