1. A method for determining potential collision with another vehicle by a vehicle equipped with a vision system, said method comprising:

  • providing, at the equipped vehicle, a vision sensor comprising a camera having at least one million photosensing elements;

    providing, at the equipped vehicle, at least one non-vision sensor comprising at least one radar sensor or at least one lidar sensor;

    capturing, using said camera, image data of an exterior environment ahead of the equipped vehicle;

    determining presence of a leading vehicle ahead of the equipped vehicle;

    when the leading vehicle is determined to be present ahead of the equipped vehicle, determining, via processing by an image processor of image data captured by said camera, that a brake light of the leading vehicle is illuminated;

    determining distance to the leading vehicle;

    determining relative velocity between the equipped vehicle and the leading vehicle;

    determining a time to collision to the leading vehicle based at least in part on the determined distance to the leading vehicle and the determined relative velocity between the equipped vehicle and the leading vehicle;

    determining a braking level of the equipped vehicle to mitigate collision of the equipped vehicle with the leading vehicle;

    employing a weighting factor when determining the braking level of the equipped vehicle to mitigate collision of the equipped vehicle with the leading vehicle; and

    adjusting the weighting factor responsive at least in part to determining, via processing of image data captured by said camera, that the brake light of the leading vehicle ceases to be illuminated.
