Embodiment approach 1

[0039] figure 1 It is a functional block diagram showing the configuration of the risk information collection device 100 according to Embodiment 1 of the present invention. Such as figure 1 As shown, the hazard information collection device 100 includes a travel information acquisition unit 101 for acquiring vehicle travel information, a dangerous state degree calculation unit 102, a visually recognizable object determination unit 103, a passenger information acquisition unit 104, and a risk causing cause candidate setting unit. 106 . The risk-inducing cause determination unit 107 and the risk-inducing cause output unit 108 .

[0040] The traveling information acquiring unit 101 acquires traveling information which is a vehicle state quantity indicating the traveling state of the vehicle, and outputs it to the dangerous state degree calculating unit 102 . The running information of the vehicle includes speed, acceleration, braking information, steering angle information, acc...

Embodiment approach 2

[0104] Figure 8 It is a functional block diagram showing the configuration of the risk information collection device 200 according to Embodiment 2 of the present invention. Figure 8 The shown hazard information collection device 200 has figure 1 In addition to the configuration of the danger information collection device 100 according to Embodiment 1 shown, a danger association information database 105 is provided. In addition, in Figure 8 in, about and use figure 1 The same configurations of the danger information collection device 100 described above are denoted by the same reference numerals, and redundant descriptions are omitted.

[0105] The danger association information database 105 stores information that associates danger for each passenger information. That is, when the passenger information is words uttered by the passenger, words associated with danger are stored. Examples of words associated with danger include "didn't see", "very dangerous", and "barely"...

Abstract

The present invention relates to a risk information collection device comprising: a risk state degree computation unit for computing a risk state degree of a travel state of a vehicle on the basis oftravel information of the vehicle; a viewed object identification unit for combining viewpoint information of the driver of the vehicle with object information of the periphery of the vehicle, identifying a label of a viewed object of the driver, and treating same as a viewed object candidate; a passenger information acquisition unit for acquiring passenger information including at least words uttered by passengers; a risk instigation factor candidate setting unit for setting, on the basis of the passenger information acquired by the passenger information acquisition unit, a risk instigation factor candidate for identifying a risk instigation factor; and a risk instigation factor identification unit for identifying the risk instigation factor on the basis of the risk state degree, the viewed object candidate, and the risk instigation factor candidate. If the risk state degree is greater than or equal to a threshold, the risk instigation factor identification unit verifies the association between the viewed object candidate and the risk instigation factor candidate, and if the viewed object candidate and the risk instigation factor candidate are associated, identifies the risk instigation factor candidate as the risk instigation factor.

Description

technical field [0001] The invention relates to a danger information collection device for collecting danger information of vehicles running on roads. Background technique [0002] When a vehicle is running on a road, a driver or a passenger may physically feel a "near miss" as a scene that feels a danger directly related to a traffic accident. Another example is that by collecting and organizing "dangerous signs" information, creating a map showing areas where traffic accidents occur, and sharing the map to prevent traffic accidents. However, in the past, consultation was used to collect "dangerous" information, and it took time and effort to sort out and input consultation results. Therefore, in Patent Documents 1 and 2, a method of automatically collecting "dangerous sign" information from travel information is proposed.
