Problems solved by technology

Therefore, there is a problem that it is impossible to give a strong stimulus when the degree of deviation is small when it is intended to give a strong stimulus when suddenly falling into a state of inattention or excitement, or when falling into a state of inattention or excitement frequently. Stimulate

Embodiment approach 1

[0026] figure 1 It is a configuration diagram showing the configurations of the driving assistance device 100 and the driving assistance system 1000 in the first embodiment.

[0027] exist figure 1 Among them, the driving assistance system 1000 includes a driving assistance device 100, a driver state detection device 200, a vehicle state information acquisition device 300, a vehicle peripheral information acquisition device 400, and a stimulus output device 500. The driving assistance device 100 includes an acquisition unit 1, a stimulus determination part 2, storage part 3 and stimulation output control part 4. A specific configuration of the driving assistance device 100 will be described later.

[0028] The driver state detection device 200 monitors the state of the driver and detects the biological information of the driver. For example, it is a camera that detects information indicating the driver's sweat, pupil size, color, expression, and line of sight by taking pictu...

Embodiment approach 2

[0108] Next, Embodiment 2 of the present invention will be described.

[0109] Descriptions of the same configuration and operations as those in Embodiment 1 are omitted.

[0110] Figure 9 It is a configuration diagram showing the configurations of the driving assistance device 100 and the driving assistance system 1000 in the second embodiment.

[0111] In Embodiment 1, the acquiring unit 1 acquires the time rate of change of the level of wakefulness as time change information, and the greater the absolute value of the time rate of change of the level of wakefulness, the stimulus determining unit 2 determines a stimulus with a higher intensity as the corresponding stimulus. The stimulus given by the driver. In contrast, in Embodiment 2, the acquisition unit 10 acquires the transition probability of the driver's waking state as time change information, and the greater the transition probability acquired by the acquisition unit 10, the stimulus determination unit 20 determin...

Abstract

Provided is a driving assistance device that assists in providing a more appropriate stimulus to a driver. A driving assistance device is provided with: an acquisition unit that acquires time change information indicating a time change in the awake state of a driver; and a stimulus determination unit that determines, as a stimulus to be given to the driver, a stimulus having a higher intensity as the larger the absolute value of the time change indicated by the time change information acquired by the acquisition unit.

Description

technical field [0001] The present invention relates to a driving support device. Background technique [0002] When driving a vehicle or a ship, it is expected that the driver is not in a dazed state of inattention or in a state of restless excitement, but in a proper state of wakefulness (proper state). In recent years, a driving support device has been proposed for constantly monitoring the driver's state and outputting a stimulus corresponding to the driver's state, thereby maintaining and guiding the driver in an appropriate state. [0003] For example, in Patent Document 1, it is described that the amount of sympathetic nerve activity and the amount of parasympathetic nerve activity are calculated based on the fluctuation of the heartbeat interval, and the stimulation is output based on whether the calculated amount of sympathetic nerve activity and the amount of parasympathetic nerve activity are above a reference value. , so that the driver's sympathetic nerve activ...
