Description

The invention relates to the field of vehicle control and can be used to display the route of movement of any vehicle, preferably land and rail transport, for example, in real time on the user's computer display, or in the form of a graphical report on the movement of the vehicle in print.

There is a method of providing cartographic information to a user through a navigation device, cartographic information corresponds to the field of view, including selecting the desired destination and displaying cartographic information, including a route to the desired destination, ground level and at least one icon raised above ground level at least one icon represents an object within the field of view [Application for invention RU 2010149280, IPC G06F 3/00, filing date 02.05.2008].

A known method of graphically displaying a route of a road network comprising forming a model electronic speed map of a road network of a settlement, which is entered into the computer memory of a central station. A road graph is created on the indicated map. Next, the optimal route is determined taking into account the specified parameters of the electronic speed map of the settlement’s road network, received by the subscriber from the central station with the possibility of visualizing on the user’s screen these routes on the indicated map and displaying the current position of the vehicle [Patent for invention RU 2377658, IPC G08G 1 / 0969, G01C 21/34, filing date 11/14/2008].

As a prototype, a method for graphically displaying a vehicle route was chosen, which consists in forming a vehicle route on an electronic map of the road network contained in the server’s memory, indicating the path value of the entire route and displaying it for the user. At the same time, the coordinates of the vehicle’s position on the vehicle’s travel route are continuously collected from the satellite communications device installed on the vehicle to the server, using the server performing the algorithmic process, the vehicle’s position on the vehicle’s travel route is determined and displayed for the user [Patent US 7231297, IPC G09B 29/00, G01C 21/26, G01C 21/34, G08G 1/123, G01C 21/32, G01C 21/00, G08G 1/0969, G09B 29/10, filing date 4.03. 2005].

The disadvantage of the prototype method is the inconvenience of finding information and its control about the position of the vehicle and the time interval relative to other vehicles moving along the same route, or control points located on the route.

The technical task is to create a way to graphically display the route of the vehicle, which allows to expand the possibilities of making logistics decisions, to provide the ability to quickly track the position of the vehicle relative to the position of control points located on the route and the total length of the route and the time interval of the vehicle from the starting point of the route to control points and end points of the route.

The technical result is the expansion of the possibilities of making logistics decisions while providing the ability to quickly track the position of the vehicle relative to the position of control points located on the route and the total length of the route and the time interval of the vehicle from the starting point of the route to the control points and the end point of the route.

Online tracking of the position and time in the vehicle’s journey allows you to increase the speed of decision-making by the user on the management of vehicles on the route.

The essence of the proposed method is as follows.

A method for graphically displaying a vehicle driving route is to form a vehicle driving route on an electronic map of the road network contained in the server’s memory indicating the path length of the entire driving route and the coordinates of the starting and ending points of the vehicle’s driving route and control points. In this case, the vehicle coordinates are collected on the server along the movement route from the device for collecting and transmitting the coordinates of the vehicle’s position installed on the vehicle. In contrast to the prototype, the route of the route is represented by the server in the form of a straight line of the route, which is displayed to the user on a computer display configured to interact with the server, or in printed form, marked on it with the start and end points of the route, control points and more by means of the server performing the algorithmic process, using the collected coordinates of the vehicle position, determine the position of the vehicle on a straight line of the route and display it for ELSE thus measure the time intervals traveled by the vehicle, a route from the starting point to each check point and an end point of the route, respectively, and display them to the user.

Thus, the inventive method allows you to expand the possibilities of making logistic decisions while providing the ability to quickly track the position of the vehicle relative to the position of control points located on the route of movement and the total length of the route and the time interval from the starting point of the route to the control points and the end point of the route.

Expanding the possibilities of making logistics decisions lies in the fact that the speed of making logistics decisions by the user and tracking results is increased. For example, if a vehicle that is located at a large distance from the control point is displayed on the user's computer screen, while the vehicle’s travel time is long, the user decides to speed up the vehicle.

Operational tracking of the vehicle’s position relative to the control points, the start and end points of the route located on the route is provided by increasing the speed of estimating the distance between objects on the route and the relative position between them. This is achieved by presenting the vehicle route in the form of a straight line of the route, which shows the position of the vehicle. Thus, it is visually much easier to estimate the distance between the vehicle and the control point, the start and end points of the route, respectively, when their positions are located on the straight line of the route, and not on the route of the vehicle shown on the map (initial view before being presented as straight route lines).

Operational tracking of the time interval between the vehicle and the control points located on the route, the starting and ending points of the route of movement is ensured by measuring the time intervals traveled by the vehicle, from the starting point of the route to each control point and end point of the route, respectively, and displaying them for user.

The path length of the entire travel route represents the distance from the start point to the end point of the travel route. The starting and ending points of the driving route limit the route of the vehicle and can be displayed to the user in the form of points, a list of vehicles located at the starting or ending points of the driving route, respectively, or of a different kind.

The collection of coordinates of the position of the vehicle on the route can be made in real time.

The control points can be the estimated stops of the vehicle along the route, intersections, shops, level crossings or other objects that control the position of the vehicle along the route of the vehicle.

Initially, a model electronic map of the road network is preliminarily formed in the server’s memory, for example, using navigation systems including specialized navigation programs.

A device for collecting and transmitting vehicle position coordinates is intended for determining vehicle position coordinates by satellite and transmitting the collected information via a wireless channel to a server. As a wireless communication channel, a satellite communication channel, GSM, Wi-fi or another wireless communication channel can be used. As a device for collecting and transmitting vehicle position coordinates, an automobile radio transceiver can be used.

The server can be made in the form of a separate computer or, for example, in the form of software installed on a computer user. The server is designed to collect vehicle position coordinates, process them and perform tasks on constructing a straight line of the route and through the implementation of the algorithmic process of determining the position of the vehicle on a straight line of the route.

In order to enable the operational tracking of the position of the vehicle relative to the position of other vehicles moving along the same route, collect on the server coordinates of the position of more than one vehicle on the route from devices for collecting and transmitting coordinates of the position of the vehicle, each of which is installed on the appropriate vehicle. Moreover, through the server performing the algorithmic process, the position of each vehicle on the straight line of the route is determined by the collected coordinates of the position of each vehicle and displayed for the user, then the position of the vehicle relative to the position of other vehicles is compared, and the time intervals covered by each vehicle are measured means, from the start point of the route to each control point and end point of the route, and display x to the user. This allows you to further expand the possibilities of making logistics decisions.

Preferably additionally measure the time intervals between vehicles moving along the same route. This allows you to further expand the possibilities of making logistics decisions due to the ability to quickly monitor the time interval of the movement of vehicles relative to the movement of other vehicles.

Additionally, in order to provide the ability to quickly track the position of the vehicle relative to another vehicle moving in the opposite direction, form the route of movement of the vehicle moving in the opposite direction on an electronic map of the road network contained in the server’s memory indicating the path length of the entire route of the vehicle moving in the opposite direction, and coordinates of the position of the starting and ending points of the route of movement of the transport means moving in the opposite direction, and the coordinates of the position of control points on the route of the vehicle moving in the opposite direction. By means of the server, the route of the vehicle moving in the opposite direction is represented in the form of a straight line of the return route, which is displayed to the user on a computer display configured to interact with the server, or in printed form together, preferably under a straight line with the mark on the straight line of the route of the reverse movement of the starting and ending points of the route of movement of a vehicle moving in the opposite direction, and control ny points. At the same time, the coordinates of the position of the vehicle moving in the opposite direction are collected from the server from the device for collecting and transmitting the coordinates of the position of the vehicle installed on the vehicle moving in the opposite direction, and then through the server that performs the algorithmic process according to the collected position coordinates the vehicle moving in the opposite direction, determine the position of the vehicle moving in the opposite direction, on straight a clear line of the reverse movement route and display it for the user, while measuring the time intervals traveled by the vehicle moving in the opposite direction, from the starting point of the route of movement of the vehicle moving in the opposite direction to each control point and end point of the route of movement of the vehicle, moving in the opposite direction, respectively, and display them for the user.

In this case, the coordinates of the position of the starting point of the route of movement of the vehicle may coincide with the coordinates of the position of the end point of the route of movement of the vehicle moving in the opposite direction. The coordinates of the position of the end point of the vehicle movement route may coincide with the coordinates of the position of the starting point of the route of movement of the vehicle moving in the opposite direction. The route of the vehicle may coincide with the route of the vehicle moving in the opposite direction, or may be different.

In order to enable the operational tracking of the position of the vehicle relative to the position of the vehicle moving in the opposite direction, after displaying the vehicle moving in the opposite direction, on a straight line of the return route, respectively, the position of the vehicle relative to the position of the vehicle moving in the opposite direction is additionally compared . This allows you to further expand the possibilities of making logistics decisions.

The position of the vehicle or the vehicle moving in the opposite direction on a straight line of the route or a straight line of the route of the return movement is determined using the algorithmic process performed by the server, for example, as follows.

The vehicle route on the electronic map of the road network is divided, for example, into segments or polygons, while the server stores the coordinates of the position of the start and end points of each segment or the coordinates of the positions of the start and end sides of each polygon. Preferably, the greatest accuracy of tracking the position of the vehicle on the route of movement is observed when the route of the vehicle is divided into segments, the smaller the length of the segments, the greater the accuracy of tracking the position of the vehicle, preferably the route of the vehicle is divided into segments from 10 to 150 m long.

If the vehicle’s route on the electronic map of the road network is divided into segments, the user sets the parking range within which the starting point of the route of movement is located, or the area of the starting point of the route of the vehicle, representing a circle preferably with a diameter of 20-100 m, or another area the starting point of the route, intended to determine the moment when the vehicle started moving along the route and save it on the server.

Next, check the location of the vehicle inside the landfill or the area of the starting point of the route. Then calculate the corresponding distance between the coordinates of the vehicle position and the coordinates of the starting point of the route. If the distance between the coordinates of the vehicle’s position and the coordinates of the starting point of the segment, the end point of which is the nearest end point of the segment, is greater than the length of the segment whose end point is the nearest end point of the segment, conclude that the vehicle is moving away from the nearest end point segment. If the distance between the coordinates of the vehicle’s position and the coordinates of the starting point of the segment, the end point of which is the nearest end point of the segment, is less than the length of the segment whose end point is the nearest end point of the segment, conclude that the vehicle is approaching the nearest end point segment. Then, the fraction of the distance traveled is calculated by calculating the ratio of the distance from the coordinates of the vehicle’s position to the starting point of the movement route to the length of the entire route of movement by summing the corresponding lengths of the segments traveled by the vehicle and parts of the route segments. Then, depending on the fraction of the distance traveled, the position of the vehicle on the straight line of the route is determined.

In order to track the convergence of the vehicle from the direction of travel of the vehicle or moving in the opposite direction, from the route of movement of the vehicle moving in the opposite direction, calculate the corresponding distance between the coordinates of the position of the vehicle or vehicle moving in the opposite direction and the coordinates of the position the closest starting or ending point of the line segment. If the distance between the coordinates of the position of the vehicle or vehicle moving in the opposite direction, and the coordinates of the position of the nearest starting or ending point is greater than the length of the segment having a large length, conclude that the vehicle or vehicle moving in the opposite direction , left the route of movement or the route of movement of a vehicle moving in the opposite direction, respectively, and stop displaying it on a straight line and the straight line of the route or the route of reverse movement, respectively.

The above algorithm allows you to most accurately determine the position of the vehicle on the route of the vehicle.

The algorithm for determining the position of the vehicle on a straight line of the route when dividing the route into polygons is similar to the algorithm for determining the position of the vehicle in a straight line of the route when dividing the route into segments, except that the position of the vehicle relative to the sides of the landfill is determined.

The position of the vehicle on the straight line of the return route can be determined in a similar way.

Also, the position of the vehicle on the straight line of the route can be determined, for example, by means of an algorithmic process, which consists in tracking the distance traveled by the vehicle from the starting point of the route by means of a server collecting information from a device for collecting and transmitting coordinates of the vehicle, and then, depending on the fraction of the distance traveled, the position of the vehicle on the straight line of the route is determined.

The time that the vehicle has traveled to each control point can be defined as the time that the vehicle has traveled to the end point of the leg of the route closest to the control point.

In order to quickly monitor compliance by a vehicle with a user-defined traffic schedule, in addition to the server’s memory for at least one control point, the time for which the vehicle must reach the control point can be set. If the vehicle has not reached the control point or has reached the specified time ahead of the specified time, then information is displayed to the user that the vehicle is late or in a hurry, respectively, for example, by tinting the vehicle, for example, in red or green, respectively, or as a text message.

The display of the position of the vehicle on a straight line of a route or a straight line of a return route for a user, respectively, can be accomplished by displaying on a computer display a user configured to interact, for example, by wire or wireless, or displaying it in a graphical report in print form by using a printer connected to a computer or otherwise.

The distance between the position coordinates of any points is calculated, for example, using the following formula:

$$\mathrm{BUT},B=R\ast ArcCos\left(Sin\left(\frac{\pi \ast \mathrm{one}\ast A_3}{180}\right)\ast Sin\left(\frac{\pi \ast \mathrm{one}<figure-callout\; id="3"\; label="\ast \; C"\; filenames="00000005.png,00000006.png"\; state="\{\{state\}\}">\ast \; </figure-callout>C_{}{}_3}{180}\right)+Cos\left(\frac{\pi \ast \mathrm{one}\ast A_3}{180}\right)\ast Cos\left(\frac{\pi \ast \mathrm{one}<figure-callout\; id="3"\; label="\ast \; C"\; filenames="00000005.png,00000006.png"\; state="\{\{state\}\}">\ast \; </figure-callout>C_{}{}_3}{180}\right)\ast Cos\left(ABS\left(\frac{\pi \ast \mathrm{one}\ast {\mathrm{<figure-callout\; id="3"\; label="D"\; filenames="00000005.png,00000006.png"\; state="\{\{state\}\}">D</figure-callout>}}_3}{\frac{180-\pi \ast \mathrm{one}\ast {\mathrm{<figure-callout\; id="3"\; label="B"\; filenames="00000005.png,00000006.png"\; state="\{\{state\}\}">B</figure-callout>}}_3}{180}}\right)\right)\right)$$

This allows you to 20-30 times increase the efficiency of making a logistic decision by the user regarding the regulation of the road situation, for example, about changing the vehicle speed.

The results of the experiments showed that the representation of the vehicle’s route in the form of a straight line of the route on which the vehicle’s position is shown makes it possible to increase the speed of distance estimation by 4–5 times and increase the speed of estimation of time intervals between objects on the route by 20–30 times: between vehicle, control points, the starting point of the route, the end point of the route and the relative position between them. Thus, the claimed method allows 20-30 times to increase the efficiency of making a logistic decision by the user regarding the regulation of the road situation, thereby expanding the possibilities of making logistic decisions.
