Abstract: A system and method for providing mechanical time dilation by pre-braking a vehicle in the event there is a collision threat so as to reduce or eliminate the need for full automatic braking if the collision becomes imminent. The system calculates a time dilation deceleration to either maintain a time to collision at a previous value before the calculation or at a predetermined value. The system also estimates a projected closing speed of the vehicle to the object at a distance that would require full automatic braking to prevent a collision. The system then determines whether the time dilation deceleration is greater than a decelerating threshold and, if so, provides automatic vehicle braking at the threshold until the vehicle comes to a full stop. If the time dilation deceleration is not greater than the threshold, then the system provides automatic braking to decelerate the vehicle at the time dilation deceleration.
