The present disclosure relates to a vehicle environment detection system (3) comprising 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 vehicle environment detection system (3) is arranged to acquire an ego velocity (v) and an ego acceleration (a) for the ego vehicle (1), and, by means of said sensor detections (9, 12), to determine vehicle data comprising:- corresponding distances (r, r) between the ego vehicle (1) and said preceding target vehicles (10, 11); and- corresponding target velocity (v, v) and target acceleration (a, a) for each of said preceding target vehicles (10, 11).The control unit arrangement (8) is arranged to determine a corresponding TTC (time to collision) between at least two different pairs of said vehicles (1, 10, 11), and to determine if any determined TTC falls below at least one threshold value.
