Title:
見通し外シナリオでの車両間ミリ波通信
Document Type and Number:
Japanese Patent JP6677327
Kind Code:
B2
Abstract:
The disclosure includes embodiments for performing beam alignment for non-line of sight (NLOS) scenarios. The method includes receiving, at a first vehicle, one or more wireless messages that include vehicle data, wherein the vehicle data describes a second vehicle position, a second vehicle speed, and a second vehicle heading. The method also includes determining sensor data. The method also includes determining an NLOS path based on the vehicle data and the sensor data so that the NLOS path avoids a potential blockage. The method also includes determining whether the NLOS path is predicted to succeed based on a beam transmission percentage satisfying a threshold percentage. The method also includes responsive to the NLOS path being predicted to succeed, performing beam alignment between the first vehicle and the second vehicle based on the NLOS path before the potential blockage is predicted to occur.
