US 12,024,175 B2 · Vehicle system for detection of oncoming vehicles

Abstract

A vehicle environment detection system in an ego vehicle, including a sensor arrangement and a main control unit is arranged to detect and track at least one oncoming vehicle, and to determine whether the ego vehicle has entered a curve. The main control unit is arranged to determine a common curve with a radius, along which common curve the ego vehicle is assumed to travel, determine a measured oncome direction of the oncoming vehicle on the common curve, corresponding to an oncome angle, determine a difference angle between the measured oncome direction and an oncome direction corresponding to if the oncoming vehicle would be moving along the common curve, compare the difference angle with a threshold angle, and to determine that the oncoming vehicle is crossing if the difference angle exceeds the threshold angle.

Dependent claims

An oncoming vehicle detection system adapted to be mounted to an ego vehicle, the oncoming vehicle detection system being configured to:

determine that an oncoming vehicle and the ego vehicle are concurrently present on a curved portion of a road;
and
determine, in response thereto:
a calculated oncome direction of the oncoming vehicle relative to the curved portion of the road;
a measured oncome direction of the oncoming vehicle based on at least one measurement of the oncoming vehicle by a vehicle environment sensor of the oncoming vehicle detection system;
and
whether a difference between the calculated oncome direction and the measured oncome direction is indicative of the oncoming vehicle being crossing traffic.
