Abstract
A method and system for autonomous collision avoidance in multiple obstacle scenarios. A forward collision avoidance system detects obstacles in front of a vehicle hosting the system and estimates a position, a velocity and an acceleration of each of the obstacles. The maneuvers which the vehicle is capable of performing that will lead to a collision with each respective obstacle are evaluated separately. The union of maneuvers which will lead to collision with any one of the obstacles is formed. The set of maneuvers which the vehicle is capable of performing through which collision with any of the obstacles may be avoided is established, and the set used for deciding how to avoid or mitigate collision with any one of the obstacles. Finally, a collision avoidance maneuver based on the decision is executed autonomously.
