Title: Radar-operated vehicle safety assurance system

Abstract: A radar-operated vehicle safety assurance system includes a radar device which detects the vehicle relative speed or range to an object. A safety limit value of the detected operating parameter is computed by means of a safety range detection or safety speed detection circuit as a function of a detected operating parameter. A visual indicator is provided which visually indicates the difference between the detected value and the computed safety limit value to allow the vehicle driver to become continuously aware of the marginal conditions of the vehicle in relation to the safety limit.
