PROBLEM TO BE SOLVED: To provide an awakening maintenance support apparatus that executes awakening maintenance support such as warning more properly, by referring to the user's awakening effort, as a parameter of a viewpoint different from the user's awakening decrease.SOLUTION: An awakening decrease A and an awakening effort E increase (phase F1). Furthermore, the awakening decrease A increases and the awakening effort E decreases, and ultimately reaches a doze or a state close thereto (phase F2). Alternatively, the awakening decrease A gradually decreases from such an extremely strong awakening decrease state, and the awakening effort E increases (phase F3). Then, the awakening decrease A decreases to some extent below, and also the awakening effort E decreases (phase F4). Also, the whole area taking the awakening decrease A in a horizontal axis and the awakening effort E in a longitudinal axis is divided into four areas A1 to A4 by setting threshold values in the awakening decrease A and the awakening effort E. The present invention is configured to select a support method according to at least one of the phases and areas. |
