DE4203930A1 - Radio controlled mobile warning system for motor vehicle - has short range channels for receiving warning of hazard conditions with transmitter for relaying signals - Google Patents

Abstract

The radio controlled mobile unit provides information regarding travelling conditions, such as fog, accidents, traffic jams. The unit has a receiver and a transmitter operating with three channels. One channel operates at 1,000 m range and another at 600 m range and responds to hazard signals in that area. A third channel has a 1,200 m range and allows received signals indicating danger conditions to be relayed to the transmitting stage to warn other road users. Keys on a front panel allow direction of track to be indicated.

Description

The invention is intended for the ongoing information of truck and car Drivers on the traffic on the road ahead Distance and resulting dangers in fog, rain, Slippery road and poor visibility while driving on car railways, serve federal and other traffic roads and accidents, especially to avoid mass collisions.

To accomplish this task, the device is included

• - a combined "receiving and transmitting part", which in two of separate from each other, each with switching and control elements equipped "function" to be selected by pressing a button Areas "across three pairs of channels with staggered coverage converts inaudible radio waves into light signals and through the range selection during operation automatically for each because of the direction of travel, as well as for the opposite traffic, directional, not mutually disturbing Builds "information flows",
• - a radio-controlled, externally visible "light signal system" for information traffic not equipped with the device Attendees,
• - An "Infor. equipped with lighting and switching elements mations- und Betriebsspult "within the motor vehicle, to Emp Catching and forwarding received signals to subsequent drivers witness,
• - one manually. if necessary, in the event of a rear-end collision using a vibrating contact automatically triggered "warning and emergency Warning system ",
• - a few steps between the window pane and the upper frame easy to attach or remove the driver's seat door, So mobile, can be dismantled and free of complex control systems, designed.

"Receiving and transmitting device" are, as mentioned, optionally by means of Switch to operate in two functional areas, namely in CB radio equipment with quartz - equipped channels.

Their range is staggered and limited, with the following Be interpretation:

Channel 1

"Remote information frequency" approx. 1000 m range, reduced speed due to Danger from emerging traffic density, wetness, smoothness, stop and go - "white parking light" with translucent traffic Sign "danger point" on signal system and "white LED" at the "information and operations desk".

Channel 2

"Near information frequency" approx. 600 m range, severely reduced speed due to considerably be impaired visibility due to fog, breakdown or accident Vehicles. Recommendation: - "Do not overtake!" - "white flashing light with traffic sign" danger point " on signal system and "yellow LED" on the "information and Operating console ".

Channel 3

"Warning" and "emergency warning frequency" approx. 1200 m range Danger of collision with standstill and traffic jam, obstacle on the road, mass accident; - "Extreme caution required" - "red flashing light" on signaling system and "information and control panel", channels 1 and 2 switched off.
Channel 3 is switched through from the receiver to the transmitter, the emergency call is automatically forwarded as long as it is not interrupted by pressing the emergency button.

Overlap when your own vehicle approaches one critical traffic situation the information frequencies of the Ka channels 1 and 2, a relay switches immediately to the near frequency, namely the higher "danger level" in order.

The received from the system and forwarded with light signals The traffic information is not an instruction, it is only an instruction Notifications that all road users to traffic-appropriate Behavior and caution when driving your vehicles to allow personal and property damage to yourself and others avoid.

That is why every road user drives independently. He does not have to stop, he may overtake if he does so after the considers the given traffic situation to be justifiable.

The information and warning signs go out when the vehicle in front Traffic becomes fluid again, the fault location has been passed and your own vehicle is increasingly moving away from the scene away.

Sender and receiver are at ease and ready to choose "N O" or "S W" button indicates this.

If a vehicle is moving from south to north with departure to the east, the driver presses the " N O" button for functional area 1. On the return trip to the south, he selects function area 2 with the " S W" button, it is located in Oncoming traffic.

On a trip from west to east, he also selects the functi onsbereich 1 by pressing the "N o". Oncoming traffic on the opposite lane is ready to receive and radio in function area 2, activated with the "S W " button, because it is heading west.

The functional area that is switched on by the Device displayed, for area 1 by a white identifier lights up on the receiver housing above the driver's door, during operation of functional area 2 by two blue optical indicators on the transmitter housing.

When changing the direction of travel and changing the route, you can after threading into the flow of traffic to both sender and Receiver of the preceding vehicles as well as those of the Inform oncoming traffic which functional area in the direction of travel is to be operated.

Claims (2)

In the features of construction, technical equipment and functional association of all components which are combined to form a whole in the division of tasks, be they as function carriers for the outside,

• - combined receiving and transmitting unit with special equipment and integrated light signal system - or the interior,
• - Information and control panel with switching and control elements -

to assign the vehicle to be equipped with the device, a self-contained, to be guided with light signals in the form of the internationally known traffic signs and warning notices, according to the loose communication system, characterized in that

• - it allows a constant exchange of information about the state, development, hindrance and endangerment of the traffic ahead and the traffic following behind at a reasonable distance on the road route used, which one follows, without radio reception and traffic-related announcements affect.
• - The operation of the system, optionally in two separate functional areas of the receiving and transmitting device, due to their purpose-specific equipment, for the direction of travel as well as for oncoming traffic, directional, mutually non-interfering information flows,
• - The selected functional area is displayed for the purpose of self-control and for the information of third parties entering the traffic by beacons which flare in two different colors, clearly visible, on the receiving or transmitting device as soon as you press the selection button,
• - the device is provided with remote and local information and a manually or automatically operated emergency warning frequency,
• Occupants of other vehicles that are not equipped with the device can participate in the transmitted information via the light signal system integrated in the outdoor device,
• the device is mobile, ie can be placed on the window in the car between the window and the upper window frame of the driver's seat door, and in this arrangement does not impair the driver's eyesight, hearing and action,
• - The information is generated on site and allows the follow-up traffic to adapt the driving behavior to the current situation in order to avoid accidents.
