1. A system for determining a following behavior for an autonomous vehicle relative to a cut-in vehicle for use in the autonomous vehicle comprising:
an onboard controls system comprising:
a speed control component that monitors and controls speed, acceleration and deceleration of the autonomous vehicle and determines a following behavior when a cut-in vehicle cuts in front of the autonomous vehicle;
an object sensing component that detects the cut-in vehicle moving into a path of the autonomous vehicle and communicates detection of the cut-in vehicle to the speed control component;
an external speed detection component that detects speed data of the cut-in vehicle and communicates the speed data to the speed control component,
wherein the speed control component determines an amount of deceleration necessary for the autonomous vehicle based on a recovery time gap, distance between the autonomous vehicle and the cut-in vehicle, the speed of the cut-in vehicle relative to the autonomous vehicle speed, and time to collision.
