US Patent 10011277 Vehicle collision avoidance

A path of a target object is predicted. A path of a non-moving host vehicle is predicted based on at least one of a predetermined host vehicle acceleration and a predetermined host vehicle speed. A threat number for the target is determined based at least in part on the predicted path of the host vehicle, the threat number indicating a probability of a collision between the target and the host vehicle. A brake is actuated when the threat number is above a threat number threshold.
