US 10,833,737 B2 · Method and apparatus for controlling multi-antenna of vehicle in autonomous driving system

Abstract

A method of controlling a multi-antenna of a reception terminal in an autonomous driving system (Automated Vehicle & Highway Systems) acquires directional information of the multi-antenna installed to receive a V2X message in the reception terminal, sets a danger expectation direction, receives the V2X message, determines a first transmission direction of the V2X message based on the directional information, and preferentially processes a V2X signal transmitted in the danger expectation direction through a preferential queue, thereby being able to prevent danger occurrence. One or more of an autonomous vehicle, a user terminal, and a server of the present disclosure may be associated with an artificial intelligence module, a drone ((Unmanned Aerial Vehicle, UAV), a robot, an AR (Augmented Reality) device, a VR (Virtual Reality) device, a device associated with 5G services, etc.

Dependent claims

A method of controlling a multi-antenna of a reception terminal in an autonomous driving system (Automated Vehicle & Highway Systems), the method comprising:

acquiring directional information of the multi-antenna installed to receive a V2X message in the reception terminal;
setting a danger expectation direction indicating the direction in which an object, which requires attention, is positioned, through first sensing information or map information;
receiving the V2X message and determining a first transmission direction of the V2X message based on the directional information;
en-queuing the V2X message to a queue mapped to the first transmission direction;
and
de-queuing the V2X message based on a preference value set in the queue,
wherein the multi-antenna includes a first antenna and a second antenna directed in a direction symmetric to the first antenna, the first transmission direction is determined based on a signal intensity difference value of the V2X message received at the first antenna and the second antenna, and the preference value is based on the danger expectation direction.
