US 11,900,795 B2 · Pedestrian device and traffic safety assistance method

Abstract

The present invention relates to a pedestrian device and a traffic safety assistance method which can effectively and properly support pedestrian's safety confirmation by utilizing vehicle-to-pedestrian communications and an AR device. A pedestrian device of the present invention includes: an ITS communication device 21 (pedestrian-vehicle communication device) configured to perform vehicle-to-pedestrian communications with an in-vehicle terminal 2; a processor 32 configured to determine if there is a risk of collision based on information transmitted to and received from the in-vehicle device, and control provision of an alert to a user of the pedestrian device; and an AR display 26 for displaying a virtual object overlaid on a real space which can be seen by the user, wherein the processor controls display of the virtual object (virtual terminal) on the AR display as an alert operation to provide an alert to the user.

Dependent claims

A pedestrian device comprising:

a pedestrian-vehicle communication device for exchanging information with an in-vehicle device mounted in a vehicle via vehicle-to-pedestrian communications;
an AR display for displaying a virtual object(s) overlaid on a real space which can be seen by a user of the pedestrian device;
and
a processor configured to:
determine if there is a risk of collision with the vehicle based on the information transmitted to and received from the in-vehicle device;
and
when determining that there is a risk of collision, control display of the virtual object(s) on the AR display as an alert operation to provide an alert to the user, wherein the display of the virtual object(s) on the AR display comprises simulated images of the user and the vehicle, showing stepwise representation of a collision scene in which the user and the vehicle gradually approach each other and finally collide.

4 more elements

A traffic safety assistance method for exchanging information between a pedestrian device and an in-vehicle device to support safety of a pedestrian and a vehicle, the traffic safety assistance method comprising:

determining, by the pedestrian device, if there is a risk of collision between the vehicle and the pedestrian based on information transmitted to and received from the in-vehicle device, and
when determining that there is a risk of collision, controlling, by the pedestrian device, display of a virtual object on an AR display, wherein the AR display displays the virtual object overlaid on a real space which can be seen by the pedestrian which is a user of the pedestrian device, wherein the AR display displays simulated images of the pedestrian and the vehicle, showing stepwise representation of a collision scene in which the pedestrian and the vehicle gradually approach each other and finally collide.
