WARNING SIGNALS FOR MOTOR VEHICLES ON GROUND COMMUNICATIONS

Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warning signal for a motor vehicle on a road

BACKGROUND OF THE INVENTION

Collision accidents often occur when motor vehicles are driven in columns, particularly in poor visibility caused by natural conditions, such as fog, rain or snow. Pursuant to the legislation on the roadworthiness of vehicles, each motor vehicle must be equipped with the prescribed lighting, stop lamps, hazard warning lights and the intensive rear fog lamp. However, the unfavorable development of traffic accidents proves that the current state of warning elements with which motor vehicles are equipped for road traffic is insufficient in critical conditions.

To solve this problem, a number of inventions and utility models have been proposed which are mainly concerned with the improvement of vehicle warning devices. Thus, the solution according to the patent application 1999-65 discloses an automatic signaling device of a motor

Solution according to MS. Patent Application 2000-24 proposes a vehicle warning device comprising a warning light switch provided with a deceleration sensor, which is further connected to the direction indicators and the horn.

These solutions involve increasing the intensity and speeding up the connection of existing signal lights. Another solution is proposed in MS. utility model 13022: It is the use of wireless connection of road users by radio frequency broadcasting. The prerequisite is that the means of transport involved in road traffic are equipped with a receiver which receives a radio, acoustic or light signal from a transmitter located stationary in places dangerous for transit. The disadvantage of this solution is the necessity to have practically all vehicles equipped with the receiver and difficult positioning of stationary transmitters.

These disadvantages are overcome by the invention described below.

SUMMARY OF THE INVENTION

The essence of the proposed technical solution is a signaling system consisting of at least a radio receiver connected to a direct current source, preferably a vehicle battery 6 V, 12 V or 24 V receiving traffic and warning signals and from a transmitter located in or near the vehicle, transmitting the signals to motor vehicles within a few hundred meters of the transmitter.

The present invention may also include a transmitter in the form of a destruction sensor located in the front of the vehicle.

The present invention will only function as a recipient of warning signals emitted by a radio placed on another vehicle or a stationary radio placed at a suitable location on the road. The technical solution without its own radio will be mobile, easily portable and can be plugged into a power source such as a plug plugged into a mounting lamp socket.

The warning signal is preferably represented by a buzzer and a red indicator located in the driver's field of vision. If the equipment includes a transmitter, vehicle drivers traveling in both directions are informed of the emergency and have sufficient time to react by slowing down the road and increasing their attention. A vehicle that leaves the Transmitter Range Zone will no longer receive warning signals.

The production and assembly of the signaling device according to the invention can be carried out by the manufacturers of the means of transport, the assembly itself can also be carried out by authorized repair shops, service centers or technical inspection stations.

·· · · ·

The present invention can also be applied across the board to further reduce the number of traffic accidents. It is clear that the application and importance of the proposed warning system for reducing the number of traffic accidents is directly proportional to the number of means of transport equipped with this system, but also to the number of transmitters emitting warning signals at the right time and place. Therefore, the proposal includes a recommendation to install a system involving a transmitter in police, fire brigade and emergency services. Activating the system could ensure that the beacon with which these visuals are mandatory is switched on. This means that the vehicles of these emergency services can emit warning signals and slow down the movement of vehicles in the critical area and on the critical road section in the daily professional activities of their crews. The signaling could be supplemented by an acoustic signal indicating the critical point with the road number and km distance. The proposed system conceived in this way could lead to increased safety of vehicles passing through the section and safety of police officers, firefighters and emergency services. The proposal also recommends the installation of warning transmitters on unprotected railway crossings where the activation of the alarm would be connected to the alternating red warning lights. Drivers who would use the alarm even in the form of a receiver with signaling elements would be within a few hundred meters of

DETAILED DESCRIPTION OF THE INVENTION

Example 1

The motor vehicle is equipped with a receiver 2 located in the driver's compartment and in the front of the destruction part the motor vehicle has a transmitter 1 in the form of a destructive sensor installed, the transmitter 1 and receiver 2 being connected to a direct current source. V, 12 V or 24 V. In the driver's compartment of the vehicle there is an acoustic signaling 3, most often represented by a buzzer, and a light signaling 4, usually represented by a red indicator light. In the event of a vehicle crash, the destruction sensor acts as an alarm signal transmitter 1 within a radius of several hundred meters. The signal is captured mainly by its own motor driver receiver 2, which activates the acoustic signaling 3 and the light signaling 4 of its own vehicle, but the signal is also received by the receivers 2 passing by or near stationary motor vehicles and operating their acoustic signaling 3 and light signaling 2 The emitted warning signal operates within a radius of about 300 m and a vehicle that leaves the transmitter's range zone stops receiving the radio signal and its protective system goes into a standstill.

Example 2

The motor vehicle is equipped with a transmitter J, a receiver 2, an acoustic signaling 3 and a light signaling 4 as in example 1. All the above devices are located in the driver's compartment, a red indicator in his field of vision. The transmitter 1 is adjusted to respond to sudden deceleration from the direction of travel of the motor vehicle. Methods of such adjustment are described, for example, in the prior art description. The decisive factor here is not the speed of the driver's reaction, but the fact that the warning signal immediately alerts vehicles traveling in both directions within a radius of about 300 m, so that they usually have enough time to react to the signaling, slow down and increase attention or stop. At the same time, the warning signal can affect the reaction of the drivers of the whole motor vehicle column.

Example 3

However, the motor vehicle does not have its own transmitter 1 but has other warning elements in the driver's compartment, ie a receiver 2, an acoustic signaling 3 and a light signaling 4. Such a set of elements is very mobile, can be carried and used in any means of transport as long as it corresponds to the required battery voltage, ie 6V, 12V or 24V. sockets for a mounting lamp or cigarette lighters.
