BACKGROUND OF THE INVENTION
In many rear-end collisions between vehicles, an extra distance of a fraction of a yard could have prevented the collision impact and the injury. This extra distance is lost at the beginning of the emergency stop, when the following driver fails to recognize the severity of the deceleration of the vehicle ahead. The following driver is wasting a precious second before initiating the full emergency braking capability of the vehicle. An early, clear, specific, and instinctively understood warning signal, based on the actual deceleration of the vehicle utilizing the Brake-Lights in combination with the Reverse-Lights, provides such a warning.
BRIEF SUMMARY OF THE INVENTION
An emergency-stop warning unit and a method for the control thereof, serve for reducing the severity and chance of rear-end collisions. The invention utilizes a deceleration or collision impact sensor, and a vehicle electric power-source, to turn on the white Reverse-Light upon high deceleration of the vehicle, for a period sufficient to put the following driver on notice of an emergency condition.
