US 2019/0100200 A1 · TRAVEL LANE IDENTIFICATION WITHOUT ROAD CURVATURE DATA

Abstract

One or more dynamic trailing objects can be detected in an external environment of a vehicle. Position data of the dynamic trailing object(s) can be acquired. It can be determined whether a current position of one of the trailing objects is at substantially the same longitudinal position as a previous position of the ego vehicle. If the current position of the dynamic trailing object is at substantially the same longitudinal position as a previous position of the ego vehicle, a lateral offset between the current position of the trailing object and the previous position of the ego vehicle can be determined. The lateral offset can be used to identify a current travel lane of the ego vehicle, determine lane crossings, and/or determine travel lane probability distributions.

Dependent claims

A method of identifying a current travel lane for an ego vehicle traveling on a road, the method comprising:

acquiring position data of a dynamic trailing object;
determining whether a current position of the dynamic trailing object is at substantially the same longitudinal position as a previous position of the ego vehicle;
and
responsive to determining that the current position of the dynamic trailing object is at substantially the same longitudinal position as a previous position of the ego vehicle, determining a lateral offset between the current position of the dynamic trailing object and the previous position of the ego vehicle.

1 more element

A system for identifying a current travel lane for an ego vehicle on a road, the system comprising:

one or more sensors configured to acquire position data of a dynamic trailing object in an external environment of the ego vehicle;
and
one or more processors operatively connected to the one or more sensors, the one or more processors being programmed to initiate executable operations comprising:
determine whether a current position of the dynamic trailing object is at substantially the same longitudinal position as a previous position of the ego vehicle;
and
responsive to determining that the current position of the dynamic trailing object is at substantially the same longitudinal position as a previous position of the ego vehicle, determining a lateral offset between the current position of the dynamic trailing object and the previous position of the ego vehicle.
