Method and device for signaling present driving intention of autonomous vehicle to humans by using various v2x-enabled application

Abstract

The invention discloses a method and a device for signaling present driving intention of autonomous vehicle to humans by using various V2X-enabled application. The method enables a driving intentionsignal transmission device to execute following steps of: (a) detecting a pedestrian ahead of the autonomous vehicle using surroundings video images, and determining whether the pedestrian crosses a roadway using a virtual crosswalk; (b) if the pedestrian crosses the roadway, estimating a crosswalking trajectory, corresponding to an expected path of the pedestrian, by referring to a moving trajectory of the pedestrian, setting a driving plan of the autonomous vehicle referring to driving information and the crosswalking trajectory, and allowing the autonomous vehicle to self-drive by the driving plan; and (c) determining whether the pedestrian pays attention to the autonomous vehicle by referring to gaze patterns and, if not, allowing delivery of the driving intention to the pedestrian and / or a nearby driver, via an external display and / or an external speaker.

Description

Technical field [0001] The present invention relates to a method and device for transmitting the current driving intention (Driving Intention) signal of an autonomous driving vehicle to others, and in particular to a method for predicting the crossing trajectory of pedestrians crossing the road of the autonomous driving vehicle (Crosswalking Trajectory) The method and device (METHOD AND Driving Plan) for setting up the driving plan of the autonomous vehicle, and when the pedestrian is not paying attention to the autonomous vehicle, makes the pedestrian recognize the driving intention of the autonomous vehicle through at least one of the external display and the external speaker (METHOD AND DEVICE FOR SIGNALING PRESENTDRIVING INTENTION OF AUTONOMOUS VEHICLE TO HUMANS BY USING VARIOUS V2X-ENABLED APPLICATION). Background technique [0002] Self-driving vehicles use various computing systems to help transport passengers from one location to another. Some autonomous vehicles can obt...

Problems solved by technology

However, in addition to the signal devices that are generally installed on manually driven vehicles (such as turn signals, headlights, high beams, brake lights, reversing lights, and some audible signals (horn, reversing light caller, etc.) ), there is no ability to directly communicate the future actions of the vehicle

Also, in addition to the driver making eye contact, waving, speaking to, or flashing his headlights to the pedestrian, slowing down or stopping at a crosswalk may be enough to give the pedestrian the message that the driver will wait for the pedestrian to cross, but Stopping a vehicle without these drivers giving the signal may not sufficiently reassure pedestrians that it is safe to cross the road
