A method of calculating a collision point between an ego vehicle and a target vehicle and to emergency-brake-assist deceleration using the calculation. The calculation defines areas of collision risk of the ego vehicle, determines movement of the ego and target vehicle, calculates times-to-collision for first and second ego-vehicle intersecting points and a target-vehicle intersecting point to an intersection point. A risk collision point condition establishes that the collision point is inside an ego vehicle area if the first time-to-collision for the first ego-vehicle intersecting point reaching the intersection point is less than a third time-to-collision for the target-intersection point reaching the intersection point, and the second time-to-collision for the second ego-vehicle intersecting point reaching the intersection point is greater than the third time-to-collision for the target intersection point reaching the intersection point. A deceleration level is selected based on the collision points satisfying the risk collision point condition.
