Description

Technical field

The technical solution of the method and the device for the warning transmission of cars falls into the field of transport technology, mainly road safety and vehicle signaling devices.

Prior art

The current state of information of drivers about the warning signal is not ensured:

• Vehicles with the right of way of driving warn other road users with an audible and light signal.

Efficiency problem: the ability to register warning signals in the vehicle cab coming from the exterior is reduced and the interior noise (audio systems, hands-free kits) is increased.

• securing railway crossings without barriers - light and sound signaling.

Efficiency problem: at level crossings without barriers due to inattention - human or weather factor.

• ensuring the signaling of a stationary vehicle forming an obstacle on the road with a warning triangle

Efficiency problem: incorrect positioning or failure to place a warning triangle, late sighting of an obstacle on a road caused by weather conditions, inattention or incorrect driving in heavy traffic, in particular on a motorway, expressway or 1st class road.

The essence of the technical solution

The method and device for warning transmission of cars is a technical solution to the problem of timely informing the driver that a vehicle with the right of way, or a train at a railway crossing without barriers or approaching a road forming an obstacle on the road is approaching it.

Warning signals from a car warning device shall be automatically transmitted by vehicles with right of way after the activation of a traffic light, or a light crossing device, or the transmission of a warning signal shall be automatically triggered on any vehicle when the direction indicator warning lights are triggered in a normal vehicle. warning triangle.

In another ordinary vehicle, by receiving a warning signal from a car alert device, the device recognizes the type of danger, such as the distance, a light and 3 seconds later an audible signal alerts the driver to the danger as well as the distance from it, disconnecting audio systems or muting sound handsfree phone set.

The shortcomings described in the prior art are eliminated by the method and device for warning car transmission as follows:

• the driver of any vehicle equipped with a car warning device will be much more familiar with incoming right-of-way vehicles with right-of-way signaling on before he can notice such vehicles visually and acoustically, also by disconnecting the audio system, and by muting the handsfree sound of the telephone set, as well as by indicating whether the right-of-way vehicle is approaching or receding.

• the driver of any vehicle equipped with a car warning device will be much more familiar with the incoming train passing through the barrier-free level crossing before he could notice such visual and audible signaling, also by disconnecting the audio system and muting the handsfree phone sound. as well as indicating whether it is approaching or receding to such a crossing.

• The driver of any vehicle equipped with a vehicle warning device will be very familiar with the vehicle constituting an obstacle on the road before he can visually notice such an obstacle, as well as by indicating whether he is bringing such a vehicle closer or further away.

The condition for the best functioning of the method for car alert transmission is the transmission and reception of a signal between the individual devices of the system on the same frequency throughout the world. It is therefore necessary that the method and equipment for car warning broadcasting be adopted uniformly throughout the world, in order to avoid complications when vehicles are moving in other countries where other frequencies would be chosen for the same type of broadcasting or other means used. technical solutions.

In order to increase the efficiency and effectiveness of the automobile warning transmission method, three different frequencies are proposed, the transmission of which is in different frequency bands, in order to achieve the highest efficiency of the automobile warning transmission method and device under changing topographic, morphological as well as weather conditions. These frequencies are:

S K 64-2019 U1

1. 917.3-918.9MHz

2. 169.4-169.475 MHz

3. 24.050-24.075 GHz

The technical solution does not provide detailed diagrams of car warning devices, as these devices will be able to be developed by several companies after registration in the system to ensure a wider variety of devices from several manufacturers, different levels of comfort of displaying output signals as well as integration into other vehicle systems depending on from the price of the device.

The car warning device must be switched on and off when the vehicle's engine is switched off, and it is possible to activate the hazard warning lights in such a state so as not to interrupt the transmission if the vehicle is an obstacle on the road and the driver leaves such a vehicle unattended.

Examples of embodiments

Device for warning transmission of cars according to picture no. 1 consists of basic components, namely connection to the power supply 5 located in the vehicle, backup power supply 4, which serves to power the device in case of failure of the power supply located in the vehicle, receiver 2 to receive signals from other car alarm devices, input for antenna 6 for receiving a warning signal, the control unit 1 ensures the functionality of the device, evaluates and determines the type of signal coming from other car warning devices and subsequently controls output 7 vehicle traffic light forming an obstacle on the road, output 8 audible warning signal delay by 3 seconds, output 9 traffic light warning of incoming train, output 10 traffic light warning of incoming vehicles with right of way, converter 13 transforms the signal from receiver 2 to control unit 1 and from control unit 1 to transmitter 3. Output 7 provides light signaling u which draws attention to vehicles forming an obstacle on the road. Output 9 provides a light signal which warns of an incoming train at a level crossing without barriers, which has a warning red light indicating the passage of the train through the level crossing. The output 10 provides a traffic light which warns of a right-of-way vehicle which has a right-of-way warning light. Output 8 provides an audible signal for all types of warning transmission and will be delayed by 3 seconds compared to the light signal due to the non-creation of shock situations for the driver. The audible and visual signals of the car alert device shall be located in the cab of the vehicle and shall ensure that the driver can clearly and quickly identify the type of alert transmit, how far away the car alert transmitter is or is approaching or moving away from it. him. Input 11 for activating the warning transmission if the vehicle is an obstacle on the road, this input is activated by triggering the hazard warning lights marked in the normal vehicle as a warning triangle button or is activated in a vehicle with right of way after triggering the driving priority warning light used in such a vehicle like a lighthouse. Antenna output 12 for transmitting a warning signal to other car warning devices.

The method for warning transmission of cars is shown in Figure no. 2. The traffic priority AP vehicle automatically transmits a signal 21 from the car warning device when the traffic priority warning light is triggered. A conventional vehicle A2 transmits a signal 22 from a car warning device when the warning turn signal lights are indicated in a conventional vehicle as a warning triangle button in the event that it forms an obstacle on the road. A conventional vehicle A1 moving on a road receives a signal 21 to a car warning device from a traffic-driving vehicle AP or receives a signal 22 from a conventional vehicle A2 when the hazard warning lights indicated in a conventional vehicle as a warning triangle button are triggered, or receives a signal 23. , which is activated by triggering a red traffic light on the ZP device at the level crossing without barriers. By receiving a warning signal from a car warning device, the device recognizes the type of danger, the distance, the light and, 3 seconds later, an audible signal to the driver of the danger as well as the distance from it, disconnecting the audio systems or mute. handsfreet phone set.
