Claim:
1. A method for use in an active safety system installed on a host vehicle, comprising the steps of: for each of a plurality of consecutively-arranged target objects in a common path in front of the host vehicle, calculating a time to collision (TTC) between the target object and the host vehicle by emitting and receiving signals underneath one or more of the consecutively-arranged target objects; for each of the plurality of consecutively-arranged target objects in a common path in front of the host vehicle, evaluating the calculated TTC to first determine which of the plurality of consecutively-arranged target objects has the lowest TTC and then to determine if the host vehicle is likely to collide with the target object corresponding to the lowest TTC; and when it is determined that the host vehicle is likely to collide with the target object corresponding to the lowest TTC and that target object is not the closest of the plurality of consecutively-arranged target objects in the common path in front of the host vehicle, triggering one or more collision avoidance measures that are designed to address the target object corresponding to the lowest TTC as opposed to the target object that is the closest of the consecutively-arranged target objects.
