Collision Avoidance System
First Claim
1. A method for avoiding a collision between a host vehicle and an intruder vehicle comprising the steps of:
- detecting an intruder vehicle within a predetermined region around the host vehicle and collecting data on the intruder vehicle position over time;
predicting a projected path of the intruder vehicle using a quadratic extrapolation of the intruder vehicle position data;
assigning a protection region around the host vehicle, and determining if the intruder vehicle projected path will intercept the host vehicle protection region and thereby determining if there will be a conflict.

Abstract
A method for avoiding a collision and a collision avoidance system for a host vehicle comprising detecting means adapted to detect an intruder vehicle within a predetermined region around the host vehicle and collect data on the intruder vehicle; means for predicting a projected path of the intruder vehicle in the host vehicle reference frame; means for determining a protection region around the host vehicle, and conflict determining means adapted to determine if the intruder vehicle projected path will intercept the host vehicle protection region and thereby determine if conflict exists between the host vehicle and the intruder vehicle.
