Abstract
A vehicle environment detection system (3) including a control unit arrangement (8) and at least one sensor arrangement (4) that is arranged to be mounted in an ego vehicle (1) and to provide sensor detections (9, 12) for at least two preceding target vehicles (10, 11). The control unit arrangement (8) is arranged to determine a resulting TTC, time to collision, between the ego vehicle (1) and a closest preceding target vehicle (10), based on an ego velocity (v0) and an ego acceleration (a0) for the ego vehicle (1), a first distance (r1) between the ego vehicle (1) and the closest preceding target vehicle (10), and that target velocity (v1, v2) and corresponding target acceleration (a1, a2) for a preceding target vehicle (10, 11) among the target vehicles (10, 11) that provide a lowest TTC value.
