Systems and methods for providing relative lane assignment of objects at distances from the vehicle

Abstract

A system for a vehicle operating on a road includes a vehicle placement module that references, based on a geographic position of the vehicle, a road mapping database to identify a selected lane of the road where the vehicle is located. A lane assignment module (i) receives information indicating identification of an object in the road and (ii) determines a relative lane of the object with respect to the selected lane. A curvature plotting module determines a curvature line of the selected lane. An object placement module (i) determines a first distance value representing a shortest distance between the object and the curvature line and (ii) determines whether the relative lane of the object is the selected lane based on the first distance value and a lane width value. An alert generation module selectively generates an alert signal in response to the object being in the selected lane.

Description

INTRODUCTION[0001]The information provided in this section is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.[0002]The present disclosure relates to vehicular sensing of surrounding objects and more particularly to systems and methods for identifying objects in the roadway on which the vehicle is operating.[0003]A vehicle may include one or more sensors to identify objects (for example, other vehicles) in front of or to the rear of the vehicle. The sensors may include, for example, a camera, a laser sensor, and / or a radar sensor. The sensors may identify objects and determine an angle and distance between the vehicle and the objects. The sensors may also identify lane markings on the ...

AI Technical Summary

Benefits of technology

The patent describes a system for a vehicle that uses a road mapping database to identify the vehicle's location on the road and the lane in which it is located. The system uses information from a camera, laser, or radar to detect objects in the road and determine their location and velocity. The system can generate an alert to the driver or a braking system based on the object's location and its distance to the vehicle. The technical effect of this system is to improve safety and efficiency for vehicles operating on the road by identifying and responding to objects in real-time, reducing the risk of collisions and improving overall driving experience.

Problems solved by technology

If an object is in the same lane as the vehicle and the distance between the object and the vehicle is decreasing, there may be a collision risk.
