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 (). When this is the case. The main control unit () is arranged to, determine an ego direction () along which the ego vehicle () travels with a corresponding ego direction angle (γ) with respect to a predetermined axis (x), determine a measured oncoming direction () of the tracked oncoming vehicle () with a corresponding oncoming angle (θ) with respect to the predetermined axis (x) during a plurality of radar cycles, determine a difference angle (δ) between the measured oncoming direction () and the ego direction (), and compare the difference angle (δ) with a threshold angle (θ), and to determine that the oncoming vehicle () is crossing if the difference angle (δ) exceeds the threshold angle (θ).
