no. 1 approach

[0058] figure 1 It is an overall configuration diagram of the traffic safety assistance system according to the first embodiment.

[0059] This traffic safety assistance system is used to assist pedestrians and vehicles in traffic safety, and includes a pedestrian terminal 1 (pedestrian device) and a vehicle-mounted terminal 2 (vehicle-mounted device).

[0060] ITS communication (pedestrian-vehicle communication) is performed between the pedestrian terminal 1 and the vehicle-mounted terminal 2 . This ITS communication is wireless communication using a frequency band (eg, 700 MHz band or 5.8 GHz band) used in a safe driving support wireless system using ITS (Intelligent Transport System: advanced road traffic system).

[0061] The pedestrian terminal 1 is held by pedestrians. In the pedestrian terminal 1, messages including location information are sent and received between the pedestrian terminal 1 and the vehicle-mounted terminal 2 through ITS communication (inter-vehicle c...

no. 2 approach

[0103] Next, a second embodiment will be described. In addition, points not particularly mentioned here are the same as the aforementioned embodiments. Figure 6 It is an explanatory diagram showing the state of AR display in the pedestrian terminal 1 according to the second embodiment.

[0104] In the present embodiment, AR display is performed using a marker image 41 representing a collision point, that is, a predicted collision point between a pedestrian and a vehicle, as a virtual object. As a result, the pedestrian can recognize the point where the collision with the vehicle will occur.

[0105] In addition, in this embodiment, the simulated image 42 of the pedestrian and the simulated image 43 of the vehicle are used as virtual objects to perform AR display. A condition in which vehicles approach and eventually collide. Thereby, the pedestrian can recognize a situation in which a collision with the vehicle may occur.

[0106] In addition, in this embodiment, the poin...

no. 3 approach

[0117] Next, a third embodiment will be described. In addition, points not particularly mentioned here are the same as the aforementioned embodiments. Figure 9 It is an overall configuration diagram of the traffic safety assistance system according to the third embodiment.

[0118] In the aforementioned embodiments, information is exchanged between the pedestrian terminal 1 and the vehicle-mounted terminal 2 through ITS communication (inter-vehicle communication for pedestrians), thereby assisting in confirming the safety of pedestrians. In this embodiment, when the user of the pedestrian terminal 1 acts as When the driver of the vehicle boards the vehicle, the pedestrian terminal 1 worn by the driver changes to the vehicle-mounted terminal mode to operate as the vehicle-mounted terminal 2, and exchanges information with the pedestrian terminals 1 held by surrounding pedestrians through ITS communication , to assist the safe driving of the driver of the vehicle.

Abstract

[Problem] To enable the confirmation of the safety of a pedestrian to be effectively or suitably aided by using a pedestrian-to-vehicle communication and an AR device. [Solution] The pedestrian device is provided with: an ITS communication unit 21 (pedestrian-to-vehicle communication unit) which performs a pedestrian-to-vehicle communication with an on-vehicle device 2; a processor 32 which decides on a risk of collision on the basis of information transmitted and received with the on-vehicle terminal, and controls an attention attracting operation for a user of an own vehicle; and an AR display 26 which overlappingly displays a virtual object in the real space viewed from the user, wherein, as the attention attracting operation, the processor controls to display a virtual object (virtual terminal) by means of the AR display in response to the risk of collision.

Description

technical field [0001] The present disclosure relates to a pedestrian device and a traffic safety assisting method that assist the safety of pedestrians and vehicles by exchanging information between the pedestrian device and the vehicle-mounted device through inter-pedestrian-vehicle communication. Background technique [0002] In recent years, the danger of walking while using portable devices such as smartphones and music players has become a problem. When walking while using a portable device, attention to the surroundings will be reduced, and sufficient safety confirmation cannot be performed. Therefore, pedestrians often fail to notice the dangerous situation and cause accidents. [0003] In addition, various technologies for realizing AR (Augmented Reality) have been proposed in the past. This AR technology is used to superimpose and display virtual objects on the real space that can be seen from the perspective of the characters, and can effectively assist the vario...
