DE3125161A1 - System for providing motor vehicles with early warning of emergency service vehicles - Google Patents

Abstract

A system for providing motor vehicles with early warning of emergency services vehicles is proposed, which system serves to provide prompt warning to drivers that emergency service vehicles (such as for example fire service, police, emergency medical services, ambulances etc.) are approaching. Above all this is intended to refer to vehicles for whose use special traffic regulations apply, for example higher speed, priority even at a red traffic light. The early warning system comprises a transmission component in the emergency vehicle and a reception and signalling component with audible and/or visual transmission in the motor vehicle. Vehicles performing an emergency function transmit, as well as the customary visual and audible signals, additional pulses or signals which can be received by appropriate devices in the motor vehicle. The received pulses/signals are decoded if necessary, amplified and converted in the motor vehicle into visual and/or audible signals which can be perceived by the driver of the vehicle (and passengers).

Description

State of the art

The invention is based on an early warning system of the genus Main claim.

A warning system is already known, but it is an immediate one there is optical and / or acoustic signaling. This system has the disadvantage that optical signals (e.g. blue light) can only be perceived if they are in possible line of sight of the driver (directly or with a mirror), not but when there are obstacles in between. The acoustic signals (e.g. 3rd Nartinshorn ) can only be perceived if they are stronger and more penetrating than that other noises that surround the driver (such as the engine of one's own vehicle, traffic noise, Music in the vehicle).

Because both signal forms are often not perceived or not perceived in time there are often serious accidents and significant disabilities for emergency vehicles.

It is an added factor that most motor vehicles have radio / cassette recorders installed or in operation and because of the increased noise level that this causes In the vehicle, the signal recording of emergency vehicles is rather random.

Advantages of the Invention The early warning system according to the invention with the Characteristic features of the main claim has the advantage that regardless of eye contact with the emergency vehicle and the noise level the respective driver is exposed by optical and / or acoustic signals in the motor vehicle warns the driver of approaching vehicles in use. You signaling is accordingly in the motor vehicle equipped with an early warning system safe even with radios / cassette recorders in operation and loud street noise, as well as in front of emergency vehicles, which with the previously usual warning system neither optically nor could be perceived acoustically enough, for example, because they came from a cross street approached.

The advantage is that the risk of accidents for motor vehicles as well as for the vehicles in use is considerably reduced.

Another advantage is that the emergency vehicles are less obstructed and can therefore be on the scene faster. This too can possibly reduce damage or be life-saving.

The measures listed in the subclaims are advantageous Further training and improvements to the early warning system specified in the main claim possible.

Exemplary embodiments of the invention are shown in the drawing and explained in more detail in the following description.

Figure 1 shows the function of the early warning system at an intersection, FIG. 2 shows an exemplary embodiment for the transmit, receive and signal part.

Figure 3 shows an example of the direction display (direction, off dez emergency vehicles approach), Figure 4 shows an embodiment for additional Send pulse, the switch-on pulse (2b).

Description of the invention In Figures 1 and 2 is the function of the early warning system in simplified form: Through the transmitter part in the vehicle in the Insert (A) transmit pulses 2a and 2b are sent continuously. This can be done on a a certain frequency that is within the reception range of radio equipment (or a reception area to be expanded) or by other waves / rays that are for the task is suitable.

The transmission pulses are generated by a corresponding receiving and signaling part received - if necessary decoded -, amplified (5) and by the transmission part 6 passed to the loudspeaker 7 and / or optical signal generator 8 on the dashboard.

It is recommended that the optical pulses 8a and possibly also the acoustic pulses 7a the usual and familiar perceptible signals of the Emergency vehicles are similar or identical. This will likely allow a faster Reaction of the power guide to the warning signals.

The optical signal generator 8 can already be connected to acoustic impulses as is the case, for example, with the relays of the direction indicators that are in operation the case is. In addition, there are acoustic impulses or tone sequences at intervals Provided via amplifier 5 and transmission part 6.

In a further embodiment of the invention (Figdurß 3) can optical signaling devices can be differentiated by the flashing one Illuminated symbol in relation to the position of the own vehicle the direction can be seen from which a vehicle is approaching in action (9 and 10).

A second exemplary embodiment is shown in FIG.

An improvement can be that the transmitter 1 at the same time to the transmission pulse 2a for optical and acoustic signaling another in short Sends time intervals as switch-on pulse 2b. This can be used to: - a corresponding Switch on receiver 4, - a radio / cassette recorder in operation to interrupt or weaken in its reproduction to only or for a short time amplifies the warning signal of the To make emergency vehicle audible.

The switch-on pulse and the associated switch-on function must match each other be matched so that the receiving and signal parts in the motor vehicle only switch on at a certain distance from the emergency vehicle. (e.g. 2-300 meters) The switch-on pulse can, if necessary, happen in the same way as it is currently happens in the case of traffic information from broadcasters.

Claims (5)

A N S P R Ü C H E 1. Early warning system for vehicles in front of vehicles in use, which is based on the fact that transmission pulses from a transmitting part A in the emergency vehicle or transmit signals are sent out by receiving and signal parts in motor vehicles received, possibly decoded, amplified (5) and into optical (8a) and / or acoustic (7a) Pulses (tones) are transmitted. The visually and acoustically perceptible signals or impulses transmitted transmission impulses of the emergency vehicles are used for the early and safe warning of approaching vehicles in action (e.g. police, fire brigade). 2. early warning system according to claim 1, characterized in that by the disorder of each functioning visitor symbol indicates the direction of the approaching one Emergency vehicle is recognizable to the position of one's own motor vehicle. (Design example Fig. 3) 5 early warning system according to claim 1 and 2, characterized in that not only transmission pulses for optical and acoustic signaling (2a), but also as Switch-on pulse (2b). This contains switch-on types in accordance with the usual forms for Activation of traffic information or others. 4. PrUiiwarnsystem according to claim 3, by the switch-on pulses (2b) Receiving parts switched on in the motor vehicle or devices in operation (Radio; cassette recorder etc) for better perception of acoustic impulses (7a) and / or reception of the transmission pulses 2a, their amplification, transmission, etc., switched will. 5. early warning system according to claim 1 to 4, characterized in that the optical signal generator (8) is already connected to the acoustic signal (independent of the acoustic impulses (7a) that are received and amplified), e.g. through P0 Relay, comparable to the acoustic signal of the direction indicators.
