Description

The invention relates to the field of ensuring road safety of vehicles and can be used to notify the driver with information about the parameters of the movement of vehicles surrounding him, which will help to avoid an emergency on road sections outside settlements.

A known method for preventing collisions of vehicles, described in (RU2676854 C2, IPC B60W 30/08; G08G 1/00, publ. the direction of the vehicle; by means of a computing device, on the basis of the corresponding signals read from the outputs of the light signaling sensors, determine the state of the vehicle control signals; carrying out the transmission of the relevant data through the transmitter of radio signals and their reception by the receiver of radio signals using smartphones; at the same time, by means of a computing device, they build a layout of vehicles transmitting their coordinates in a given spatial area and display the layout of vehicles on an indicator; moreover, if necessary, when receiving signals from other vehicles, signals are generated that warn the driver about dangerous traffic situations.

A feature of the functional implementation of this method is that in each individual smartphone that is used on a vehicle, a satellite navigation signal receiver, a radio signal receiver, a computing device and a radio signal transmitter are structurally placed.

The disadvantage of this method is a decrease in road safety due to untimely warning of the driver about dangerous traffic situations, due to the peculiarity of the functional implementation of this method.

With such a functional implementation of this method, a smartphone that is used on a vehicle actually multitasks, processing in real time a large amount of data on a plurality of vehicles. Such a multitasking mode of this smartphone causes its high workload in general and, as a result, leads to an increased risk of failure in the exchange of data between vehicles. As a consequence, a failure in the exchange of data between vehicles leads to an untimely warning of the driver about dangerous traffic situations.

In addition, such a multitasking mode of this smartphone also causes a high workload of the computing device in particular and, as a result, leads to a decrease in its computing speed and computing power. The decrease in the speed of computing and the computing power of the computing device also leads to an untimely warning of the driver about dangerous traffic situations.

A known method for preventing traffic accidents is described in (RU2711835 C1, IPC B60R 21/00; B60Q 1/00; G01S 19/48; G08G 1/00; G08G 1/09; G06Q 10/06, publ. 01/22/2020 ), including receiving from the user through a remote computer device information about the user, containing the location and current time; storing in a database accident-related data on one or more types of data; selectively extracting from the database a portion of the accident-related data corresponding to the user's specified location; selectively generating, by the notification processor, a notification for the specified location based on the selectively extracted portion of the accident-related data, the notification containing the cause of one or more accidents at the given location or recommendations for preventing a potential accident at the given location.

The disadvantage of this known method is also a decrease in road safety due to untimely warning of the driver about dangerous traffic situations due to high processor load in general and low database performance in particular when processing a large data array.

There is an interactive method for collecting information about the traffic situation and prompt notification of its participants, described in (RU87820 U1, IPC G08G 1/00, publ. from a remote server, an updated version of the road situation map, track the position of a road user using GPS signals; at the same time, when the car passes a road event, an event data packet is formed that identifies the type of event and the point of the event, determined by the module of the GPS/GLONASS satellite navigation system, and transmits it via a cell phone packet data channel to a remote server located in the global information network ; and on the side of the remote server, the incoming event signal is checked for reliability and, after statistical processing, the event is placed in the roadmap plan; when approaching the appropriate place, sound signals are given to the client, notifying the latter, and thereby warns the driver about the upcoming features of the route.

As a result of the implementation of this method, the road user is only notified of the approach to the location of the traffic accident (CTA).

The closest technical solution (prototype) to the claimed invention is a method for preventing collisions of vehicles on road sections outside settlements, described in (CN106960604 A, IPC G08G1 / 01; G08G1 / 0967; G08G1 / 16, publ. , which consists in the fact that a data packet is formed for each i-th road user, including the current coordinates (x _ij , y _ij ) of the vehicle of each i-th road user on the j-th road section outside settlements, obtained by the corresponding receiver of satellite navigation signals, and identifying the number of the cellular communication device of each i-th road user with access to the Internet; a data stream containing the generated data packets of N road users, including the current coordinates (x _Nj , y _Nj ) of vehicles of N road users on the j-th section of the road outside settlements and identifying the numbers of the corresponding cellular communication devices of N road users , in real time via the Internet, transmitting to a remote server configured to send in real time via the Internet to the corresponding cellular communication device of the i-th road user an alarm signal generated in the process of analytical processing of the received data stream; in the process of analytical processing of the received data stream on the side of the mentioned remote server _{, the current speed υ ij and the} direction movement of the vehicle of each i-th road user on the j-th section of the road outside settlements; in the process of analytical processing of the received data stream on the side of the said remote server, the current speed υ _ij of each i-th road user is compared with a given speed υ _back of traffic on the j-th section of the road outside settlements; if the current speed υ _ij of the i-th road user on the j-th section of the road outside the settlements exceeds the specified speed _υ of the road traffic on the j-th section of the road outside the settlements, then to the corresponding cellular communication device of the i-th participant traffic in real time via the Internet, a generated alarm is sent containing the corresponding emergency code, triggering on board the corresponding vehicle of the i-th road user the reproduction of an early warning sound signal about an emergency situation that has arisen due to the excess of the corresponding vehicle of the i-th speed mode road user on the j-th section of the road outside settlements.

As a result, with such a functional implementation of the prototype, the road user is only notified about exceeding the speed limit on road sections outside settlements.

However, according to statistics, the occurrence of an emergency on road sections outside settlements is caused not only by the vehicle exceeding the speed limit on road sections outside settlements, but also by insufficient or limited visibility in front of a vehicle moving on a road section in various weather conditions.

In addition, the risk of an emergency increases in the event of a pre-accident conflict road traffic situation between the vehicles of road users that has developed as a result of their non-observance of the safety distance, but at the same time is characterized by the technical ability of road users to prevent an emergency. situation.

According to statistics, the untimely warning of an emergency situation that arose as a result of the formation of a pre-accident conflict road traffic situation between the vehicles of road users is fraught with the following types of road traffic accidents (RTA):

• passing collision: occurs in case of formation of a pre-accident conflict road traffic situation between the vehicles of road users moving on a road section in the passing direction;

• Oncoming collision: occurs in case of formation of a pre-accident conflict road traffic situation between the vehicles of road users moving on a section of the road in the opposite direction;

• Collision at the crossroads of unequal roads: occurs in the event of a pre-accident conflict road traffic situation between the vehicles of road users, one of which is moving along the main road, and the other is leaving the secondary road for the main one.

Thus, the general disadvantage of the method and prototype known from RU87820 is a small set of capabilities for notifying a road user about the occurrence of various emergency situations on road sections outside settlements, which reduces the effectiveness of the road user notification function as a measure to improve road safety on the road. road sections outside built-up areas.

After that, the received package of cartographic data is recorded and stored in the corresponding database in the data storage subsystem 142.

At step 205 of receiving the data stream on the side of the remote server 14 of the claimed method 200 from the storage 152 of traffic safety data, the block 141 of receiving the data stream in real time via the Internet network 13 receives a data packet about the current indicators of the state of traffic safety on the j-th section of the road outside settlements, which is then recorded and stored in the appropriate database in the data storage subsystem 142.

In addition, at step 205 of receiving a data stream on the side of a remote server 14 of the claimed method 200, from the meteorological data storage 153 of the unit 141 of receiving a data stream in real time via the Internet network 13, it receives a packet of weather data on the j-th section of traffic outside settlements , which is then recorded and stored in an appropriate database in the storage subsystem 142.

Then the claimed method 200 proceeds to step 210 of analytical processing of the received data stream on the side of the mentioned remote server 14, on which, according to the change in time of the current coordinates (x _ij ,y _ij ) of the vehicle of each i-th road user on the j-th section of the road outside settlements, by means of subsystem 143 for analytical processing of the received data stream, it is possible to determine the current speed υ _ij and the direction of movement of the vehicle 10 of each i-th road user on the j-th section of the road outside settlements.

The current speed υ _ij and the direction of movement of the vehicle 10 of each i-th road user on the j-th section of the road outside the settlements, obtained at step 210 of analytical processing of the received data stream on the side of the remote server 14 of the claimed method 200, are recorded in the appropriate database in the storage subsystem 142.

After that, the claimed method 200 proceeds to step 215 of analytical processing of the received data stream on the side of the remote server 14, which provides for comparing the calculated current speed υ _ij of each i-th road user with a given speed υ _back of traffic on the j-th section of the road outside settlements, the value of which is stored in the corresponding database in the data storage subsystem 142.

If the current speed υ _ij of the i-th road user on the j-th section of the road outside the settlements exceeds the specified speed υ _back of traffic on the j-th section of the road outside the settlements, then the execution of the claimed method 200 proceeds to the step 220 of sending alarm to the vehicle 10, otherwise - to step 225 analytical processing of the received data stream.

At step 220 of sending an alarm signal to the vehicle 10 of the claimed method 200 from a remote server 14 in real time via the Internet network 13, it is planned to send the alarm signal generated during analytical processing of the received data stream containing the corresponding emergency code to the corresponding cellular communication device 101 i-th road user.

If the condition for generating an alarm signal, expressed by formula (1), is met, at step 220 of sending an alarm signal to the vehicle 10 of the claimed method 200, by means of the subsystem 143 of analytical processing of the received stream of the remote server 14, an alarm signal is generated containing an emergency code that has arisen due to exceeding by the corresponding vehicle of the i-th road user of the speed limit on the j-th section of the road outside the settlements.

In a particular embodiment of the claimed method 200, at step 220 of sending an alarm signal to the vehicle 10 by means of the generated alarm signal sending unit 144, before sending the generated alarm signal in real time via the Internet network 13 to the corresponding cellular communication device 101 of the i-th road user, containing the corresponding emergency code, its encryption is provided.

In a private embodiment of the claimed method 200, this step first provides for receiving in real time via the Internet network 13 by means of the GSM module 105 of the cellular communication device 101 of the i-th road user a generated and encrypted alarm signal containing the corresponding emergency code, and then - decryption of the received alarm signal containing the corresponding emergency code by means of the processor 106. The decrypted code of the corresponding emergency situation is sent to the audio-video subsystem 107 of the corresponding cellular communication device 101.

If the condition for generating an alarm signal expressed by formula (1) is met, at the step of receiving the generated alarm signal by the corresponding cellular communication device 101 of the claimed method 200, the code of the corresponding emergency situation through the audio-video subsystem 107 starts on board the corresponding vehicle 10 of the i-th road user movement playback of an early warning sound signal about an emergency situation that arose as a result of the corresponding vehicle 10 exceeding the i-th road user speed limit on the j-th section of the road outside settlements.

Playing an early warning sound signal for exceeding the speed limit provides a warning of the corresponding emergency situation on the j-th section of the road outside the settlements.

At step 225 of the analytical processing of the received data stream on the side of the mentioned remote server 14 of the claimed method 200, it is provided for the simultaneous determination of the average coefficient of adhesion υ _ij of the tires of the vehicle 10 of the i-th road user with the road surface of the j-th section of the road outside settlements and the visibility distance S _{j view} on the j-th section of the road outside settlements.

As seen in FIG. 4-6, the visibility distance S _{j view} on the j-th section of the road outside the settlements is the minimum required distance at which a road user must see the road in front of him in order to notice obstacles and avoid them in a timely manner.

The visibility distance S _jview on the j-th section of the road outside the settlements is determined on the basis of the analytical processing of the received data on weather conditions on the j-th section of the road outside the settlements.

To determine the visibility distance S _{j view} on the j-th section of the road outside the settlements, the subsystem 143 for analytical processing of the received data stream refers to the corresponding tabular data (see table 1) stored in the corresponding database in the data storage subsystem 142 of the remote server 14.

Table 1 shows the general road visibility conditions under various weather conditions described in (Table of road visibility conditions general Transport and vehicles Reference tables [online] [retrieved 2021-07-15] Retrieved from <https://infotables.ru/avtomobili/ 1103-usloviya-vidimosti-dorogi-tablitsa#hcq=SuTPdDs>).

The average friction coefficient υ _ij tires of the vehicle 10 of the i-th road user with a road surface of the j-th section of the road outside the settlements is determined based on the analytical processing of the obtained data on weather conditions on the j-th section of the road outside the settlements, taking into account the type of road coatings on the j-th section of the road outside settlements.

To determine the average coefficient of adhesion υ _ij tires of the vehicle 10 of the i-th road user with the road surface of the j-th section of the road outside the settlements, the subsystem 143 for analytical processing of the received data stream refers to the corresponding tabular data (see table 2) stored in the corresponding database in the data storage subsystem 142 of the remote server 14.

Table 2 shows the reference values of the coefficient of adhesion of tires of public vehicles, taking into account weather conditions and taking into account the type of road surface, described in (Vakhlamov V.K. Cars: performance properties: a textbook for university students - M .: Publishing Center "Academy", 2006, p. 38).

The average friction coefficient ϕ _ij of the tires of the vehicle 10 of the i-th road user with the road surface of the j-th section of the road outside the settlements and the visibility distance S _{j view} on the j-th section of the road outside the settlements obtained at step 225 of the analytical processing of the received flow data on the side of the remote server 14 of the claimed method 200 is written to the appropriate database in the data storage subsystem 142.

Then the execution of the claimed method 200 proceeds to step 230 of generating an interactive traffic map on road sections outside settlements.

At step 230 of generating an interactive road map on road sections outside populated areas of the claimed method 200, visualization of the generated interactive road map on the j-th road section outside populated areas, stored in the corresponding database in the data storage subsystem 142 of the remote server 14, is provided by means of the subsystem data display 145.

The generated interactive traffic map on the j-th section of the road outside the settlements, visualized by the data display subsystem 145 of the remote server 14, reflects the type of road surface on the j-th section of the road outside the settlements, the relief of the j-th section of the road outside the settlements, detailing relevant technical means of organizing traffic on the j-th section of the road outside the settlements, the visibility distance S _{j view} on the j-th section of the road outside the settlements, current coordinates (x _Nj , y _Nj ) and directions of movement of vehicles N road users on j th section of the road outside settlements.

Then the execution of the claimed method 200 proceeds to step 235 of analytical processing of the received data stream on the side of the remote server 14, on which, based on the relevant current indicators of the state of road safety, it is provided to identify the J-th emergency zone on the generated interactive traffic map on the j-th a section of the road outside the settlements, visualized by means of the data display subsystem 145 of the remote server 14.

On the generated interactive map of traffic on the j-th section of the road outside the settlements, visualized by the data display subsystem 145 of the remote server 14, the J-th emergency zone on the j-th section of the road outside the settlements is a section of the road outside the settlements ( see Fig. 4-6), in which, according to the relevant indicators of the state of road safety for the current period, three or more accidents were committed, regardless of their type, as a result of which road users (people) were killed or injured.

At the same time, the value of the J-th emergency zone does not exceed 1000 meters from the location of the accident on the j-th section of the road outside settlements.

If on the generated interactive traffic map on the j-th section of the road outside the settlements, on the basis of the corresponding current indicators of the state of road safety, the J-th emergency zone is detected, then the execution of the claimed method 200 proceeds to step 240 of analytical processing of the received flow data on the side of the said remote server 14, otherwise it returns to step 205 of receiving the data stream by the remote server 14, where the received data stream is updated.

At step 240 of analytical processing of the received data stream on the side of the mentioned remote server 14 of the claimed method 200 by means of the subsystem 143 of analytical processing of the received data stream based on the current coordinates (x _Nj , y _Nj ) of vehicles 10 N road users on the j-th section of the road outside settlements, first, the number of vehicles of 10 road users located in the identified J-th emergency zone on the j-th section of the road outside the settlements is counted, and then the vehicles of 10 road users located in the identified J-th emergency zone, in pairs.

Then, at step 240 of analytical processing of the received data stream on the side of the mentioned remote server 14 of the claimed method 200, for each k-th pair of vehicles of road users located in the J-th emergency zone, by means of the subsystem 143 of analytical processing of the received data stream, it is provided determination of the corresponding actual distance S _kJact and minimum safety distance S _kJmin .

The actual distance S _kJact and the minimum safe distance S _kJmin for the k-th pair of vehicles of road users located in the J-th emergency zone are determined depending on the situation identified on the generated interactive traffic map on the j-th section of the road outside the settlements, rendered by the display subsystem 145 of the remote server 14, namely:

• type 1 situation: the corresponding vehicles of 10 road users in the k-th pair of vehicles of road users located in the J-th emergency zone are moving in the same direction on the j-th section of the road outside settlements (see Fig. . 4);
