DD209152A1 - SUSPENSION SYSTEM FOR VEHICLES - Google Patents

Abstract

The invention relates to a warning system, which ensures the required safety distance in vehicles, preferably motor vehicles when driving in the dark. According to the invention, this is achieved by arranging light-sensitive electronic components at the rear of the vehicle, which impart an electrical impulse via an electronic threshold value switch to an electrical power switch upon striking the light beam of the following traffic, which switches on a warning light which is likewise arranged at the rear. By means of a potentiometer, the sensitivity level is regulated according to the respective required safety distance.

Auffahrwarnsystem for vehicles Field of application of the invention

The invention relates to a warning system which guarantees the required safety distance in vehicles, preferably motor vehicles, when driving during darkness.

Characteristic of the known technical solutions

In the known technical solutions is essentially a radar warning system the necessary information on safety f ^ \ uniform spacing and possibly signals displayed. Thus, it is known that a radar beam makes azimuthal movements and sends information to a receiver when hitting an obstacle. The obstacle itself must be provided with reflective layers. Furthermore, it is known that at the rear of the vehicle signal transmitter and at the bow of! Tachfolgeverkehrs ultrasonic signal generator bzv /. Receiver are installed. The distance display is carried out in follow-up traffic.

Also known is an optical and acoustic warning when exceeding a predetermined distance by means of ultrasonic transmitter / ultrasonic receiver.

It is also known an electronic distance automatic for driving vehicles, where a test beam detects the preceding vehicle and the beam reflected from the preceding vehicle is transmitted via a computer system to an engine control system. These known warning systems are in their mode of operation more effective, but have the significant disadvantage that they are very expensive in their production and maintenance. In addition, there is a disadvantage in that the signal transmitter or signal receiver must be attached as accessories to the vehicle.

Object of the invention

The invention aims to provide a simple and cost-effective in its technical scope warning system, which warns vehicles when driving in the dark before driving on a vehicle in front.

Explanation of the essence of the invention

The invention is based on the object, to avoid AuffahrUnfallen when driving in the dark to create a 7 / arnsystem, which indicates your vehicle ahead of a subsequent vehicle when this falls below the required safety distance .. According to the invention this is achieved in that the rear end of the vehicle in front photosensitive components are arranged, on which the light beam of the Fachfo! vehicle meets, whereby a 7 / arnleuchte is operated via a previously known circuit, which is also located at the rear end of the vehicle in front. Arnleuchte can be adopted by the existing on the vehicle taillights or by an additional JTebelschlußleuchte or by an additionally arranged warning light · It is possible, connected to the circuit and arranged on the dashboard control lamp as a control for the funct In order to tune the required safety distance according to the journeys within built-up areas, on highways or trunk roads or other influencing factors, such as levers, a potentiometer is arranged to the known circuit with which the sensitivity threshold of the electronic threshold switch is regulated accordingly · To simplify the design of the system, it is possible to arrange the photosensitive electronic component within the taillights on the vehicle or within the additional Tiarnleuchten.

The accompanying drawing shows the preceding vehicle 4 with its rear end 1 and an additionally arranged warning light 2 and the following vehicle 5 2iit with the lights 3. Correspondingly required safety distance is the driver of the vehicle 4 via a potentiometer set the sensitivity threshold of the electronic threshold switch. When approaching the vehicle 5 to the vehicle 4, the light beam of the vehicle 5 hits - ^u £ the photosensitive elsk-

tronische Bauelement 6. Upon reaching a certain set by the potentiometer light value is given by the photosensitive electronic component 6, an electrical pulse on the electronic threshold value switch to an electrical circuit breaker, which turns on the warning light 2. Only when falling below the set light value, the warning light 2 is switched off again by the voltage drop across the photosensitive electronic component 6.

The advantage of the invention is the cost-effective design of the warning system and its high efficiency. Compared to known, similarly acting systems, such as radar, radio or Doppler effect, there is no transmitter, since this puncture is taken over by the illumination device of the follower vehicle. The already in circulation vehicles can be easily retrofitted.
