1. A method for collision avoidance using automated braking and steering comprising:

  • determining an actual distance to an obstacle in a path of a vehicle;

    determining a relative velocity between said obstacle and said vehicle;

    determining a first distance sufficient to avoid collision by braking only;

    determining a second distance sufficient to avoid collision by combined braking and steering around said obstacle;

    applying braking if at least one of, said first distance exceeds said actual distance and said first distance is within a selected threshold of said actual distance; and

    if said actual distance exceeds said second distance and a lane change is permitted, applying steering control to affect a lane change.
