1. A method of assisting a driver in avoiding a collision between a host vehicle and an obstacle in a lane of travel, the method comprising the steps of:

  • identifying a collision threat with the obstacle;

    recursively calculating a time-to-collision;

    recursively generating an optimal collision avoidance path to a target lane for avoiding a collision with the forward driven vehicle, wherein recursively generating the optimum collision avoidance path is determined by a processor and is based on a position and a speed of the host vehicle relative to the obstacle and an updated calculated time-to-collision;

    determining whether the driver of the vehicle has initiated a steering maneuver to avoid the obstacle;

    enabling steering assist for maintaining the host vehicle along the optimum collision avoidance path, the steering assist applying a torque by a steering mechanism for producing steering adjustments to assist in guiding the host vehicle along the optimum collision avoidance path to the target lane; and

    recursively adjusting the steering assist torque by the steering mechanism based on a recent updated optimum collision avoidance path.
