Description

Method for coordinating movement of vehicles forming a convoy

technical field

The invention relates to a method for coordinating the movement of vehicles forming a platoon.

Background technique

It is well known that vehicles, especially motor vehicles, form a convoy to protect at least one of them, said one vehicle being the main vehicle for transporting eg VIPs (Very Important Persons) such as politicians or celebrities. Primary vehicles are protected by other vehicles called secondary vehicles. The task of the secondary vehicle is, for example, to isolate other vehicles from the primary vehicle so that safe transport of VIPs can be achieved. For example, a secondary vehicle is used to block the intersection while the primary vehicle is crossing the intersection. The main task is to avoid a complete stop of the convoy. To this end, the vehicles perform several driving maneuvers in which the vehicles can move at different speeds relative to each other.

Contents of the invention

technical problem to be solved

It is an object of the invention to provide a method that can facilitate the execution of such driving maneuvers in a fast, simple and safe manner.

This object is solved by a method having the features of patent claim 1 . Advantageous embodiments with advantageous developments are indicated in other patent claims.

Technical solutions

The invention relates to a method for coordinating the movement of vehicles forming a convoy, in particular motor vehicles, wherein one vehicle is a primary vehicle to be protected by other vehicles acting as secondary vehicles of the convoy. In the method, telematics data are received by the vehicle via a wireless data connection, the telematics data comprising position data representing the respective position of the vehicle. Furthermore, the telematics data comprise movement data representing at least one driving maneuver to be performed by the vehicle. By providing the vehicle with telematics data wirelessly, it is possible to provide the vehicle with up-to-date, in particular real-time, data while the vehicle is moving. The driving maneuver can thus be carried out in a particularly easy, fast and safe manner by the driver of the vehicle on the basis of the received data. Since information data are provided to the individual vehicles and thus to the individual drivers, the respective positions of the vehicles, in particular relative to each other, can be taken into account when starting and executing the driving maneuver.

Undesired vehicle positions such as excessive distances between the vehicles can thus be avoided, so that the primary vehicle can be protected particularly effectively by the secondary vehicle.

In an advantageous embodiment of the invention, the driving maneuvers of the fleet indicated by the movement data are schematically displayed on at least one respective display unit of each vehicle. In other words, the respective display of the vehicle can schematically display the driving maneuver on the basis of the received telematics data, so that the driving maneuver is communicated to the respective driver. For example, the driving maneuver is shown schematically in such a way that the display unit displays individual symbols representing the vehicles of the fleet, which symbols move relative to one another in order to illustrate the driving maneuver, ie its course.

In a more advantageous embodiment of the invention, the telematics data comprise object data representative of at least one object in the surroundings of the vehicle fleet. The driver can thus perform a driving maneuver based on this target, so that, for example, a collision between the convoy and the target can be avoided. In addition, the main vehicle can be effectively protected from the damage of the target.

Preferably, the object is detected by at least one object detection system of the vehicle. For example, an object detection system includes at least one sensor by means of which an object can be detected. The vehicle can thus be supplied with up-to-date, in particular real-time object data, so that driving maneuvers can be carried out based on objects detected in the surroundings of the convoy.

In a further advantageous embodiment of the invention, the vehicle receives traffic data in which the current traffic situation of the vehicle is represented. Thus, the driver can, for example, adapt the speed and movement of the vehicle to the prevailing traffic situation when performing a driving maneuver.

In a more advantageous embodiment of the invention, the telematics data are provided by at least one database to which the vehicle is wirelessly connected via a wireless data connection. Therefore, the latest real-time data can be provided to the vehicle. Furthermore, the vehicles share the same information base from which the driving maneuvers can be carried out.

In a more advantageous embodiment of the invention, the information data are exchanged wirelessly between wireless data connections. This means that vehicles share their information so that all vehicles in the fleet have the same information base on which to perform driving maneuvers.

Preferably, the telematics data are exchanged directly between the vehicles via a wireless vehicle-to-vehicle data link. This means that telematics data are not transmitted from one of the vehicles to the other vehicles via an intermediate server, but rather from eg one of the vehicles directly to the other vehicles of the fleet, without redirection of the telematics data via an external server. As a result, up-to-date, in particular real-time, data can be provided to the vehicle particularly quickly, so that the primary vehicle can be protected particularly effectively and robustly.

Further advantages, features and details of the invention result from the following description of preferred embodiments and the drawings. Features and feature combinations mentioned above in the description as well as features and feature combinations mentioned in the following description of the figures and/or shown individually in the figures can be used not only in the respectively shown combination but also in the Any other combination or application alone without departing from the scope of the present invention.

detailed description

In the drawings, the same elements or elements having the same function are denoted by the same reference numerals.

FIG. 1 shows in a schematic top view three vehicles 10 , 12 and 14 traveling along a road 16 , the vehicles 10 , 12 and 14 forming a convoy 18 , wherein the vehicles 10 , 12 and 14 and thus the convoy 18 are in the direction of the directional arrow 20 Move in the indicated direction. Currently, the vehicles 10, 12 and 14 are moving straight ahead.

The vehicles 10 , 12 and 14 perform a first driving maneuver in which the vehicles 10 , 12 , 14 configured as motor vehicles travel at least substantially constant distances d1 and d2 each and to each other. This means that during said first driving maneuver, the vehicles 10, 12 and 14 move in such a way that the distance d1 between the vehicle 10 and the vehicle 12 and the distance d2 between the vehicle 12 and the vehicle 14 are in the first driving maneuver remains at least approximately constant. The first drive maneuver is also known as traditional front and rear protection while driving straight at high speed.

In the fleet 18, the vehicle 12 is the main vehicle, also referred to as a VIP vehicle, since a very important person (VIP) is carried in the vehicle 12 . For example, very important people are celebrities or politicians who are protected from targets and other traffic participants. It can be seen from FIG. 1 that the distance d1 corresponds substantially to the length of at least two vehicles 10 and the distance d2 corresponds to the length of three vehicles 14 .

The other vehicles 10 and 14 are so-called secondary vehicles by which vehicle 12 and thus the VIP are protected. Among other things, a driving maneuver is performed to effectively and effectively protect the vehicle 12 while traveling along the road 16 .

In order to carry out the first driving maneuver in a fast, safe and simple manner, the first driving maneuver is carried out on the basis of a method of coordinating the movement of the vehicles 10 , 12 and 14 during said driving maneuver. In the method, telematics data are received by the vehicles 10, 12 and 14 via a wireless data connection, the telematics data comprising position data representing the respective positions of the vehicles 10, 12 and 14 and representing at least Movement data for the first driving maneuver.

For example, at least some of the received telematics data is displayed via the respective displays of the vehicles 10, 12, 14 to schematically illustrate the first driving maneuver such that the first driving maneuver is visually communicated to the respective displays of the vehicles 10, 12, 14. respective drivers. Each driver thus knows, for example, the position of other vehicles 10 , 12 and 14 relative to their own vehicle 10 , 12 and 14 , so that the driver can precisely execute the first driving maneuver based on the received telematics data. For example, the telematics data is provided by an external server having a database of telematics data stored therein, wherein the telematics data is wirelessly transmitted to and received by the vehicles 10 , 12 and 14 .

Additionally or alternatively, at least one of the vehicles 10 , 12 and 14 may provide telematics data that is wirelessly transmitted to each of the other vehicles 10 , 12 and 14 . Preferably, vehicles 10 , 12 and 14 exchange information data directly via a wireless vehicle-to-vehicle data connection, ie a wireless vehicle-to-vehicle data connection. Accordingly, telematics data is up to date and may be received by vehicles 10, 12, and 14 in at least substantially real time. Since individual drivers can perform driving maneuvers based on the latest information data, collisions between the vehicles 10, 12, and 14, and collisions between objects such as other traffic participants and the vehicles 10, 12, 14 can be avoided, such that Primary vehicles can be protected particularly strongly and effectively.

FIG. 2 shows a fleet 18 that includes not only secondary vehicles in the form of vehicles 10 and 14 and a primary vehicle in the form of vehicle 12 , but also secondary vehicles 22 , 24 and 26 . In FIG. 2 , the second driving maneuver is performed by the vehicle fleet 18 . The second travel maneuver is also referred to as a left turn barrier because, in the second travel maneuver, the convoy 18 turns left at the intersection 28 while protecting the primary vehicle (vehicle 12 ).

In a first step S1 of the second driving maneuver, the convoy 18 approaches the intersection 28 while driving straight ahead at high speed. In a second step S2 a left turn is made in such a way that the vehicles 10 , 14 and 24 block the opening of the roads 16 , 30 and 32 to the intersection 28 , wherein the vehicles 10 , 14 and 24 are moving slowly. Additionally, vehicles 22 and 12 are turning left at high speed while vehicle 22 is moving in front of vehicle 12 . Additionally, vehicle 26 is moving at high speed behind vehicle 12 and making a left turn, protecting the rear of the primary vehicle.

In a third step S3 , the vehicles 10 , 14 and 24 are accelerated such that the vehicle 10 moves between the vehicle 12 and the vehicle 22 and the vehicle 26 moves between the vehicle 10 and the vehicle 12 .

In the fourth step S4 , the left turn is completed, and the convoy 18 moves along the road 34 in the sequence shown in FIG. 2 , wherein the convoy 18 travels in a straight line at high speed. The idea behind the second driving maneuver is to protect the primary vehicle and keep it in the convoy 18 without being exposed to other traffic participants. The second driving maneuver is performed based on the received telematics data, so that the drivers of the vehicles 10, 12, 14, 24 and 26 can quickly and easily find their respective positions in the fleet 18, so that the fleet 18 in the fourth step S4 have their desired order. In other words, the position data is used to generate the correct and desired order of the fleet 18 .

FIG. 3 shows a third driving maneuver which is likewise carried out based on the method. The third driving maneuver is also referred to as a VIP-U-turn, in which the motorcade 18 makes a U-turn on the road 16 .

In a first step S1 , the convoy 18 travels straight ahead at high speed on the road 16 with the main vehicle protected by the vehicle 10 facing forward. Additionally, vehicle 12 is laterally protected by vehicle 14 . Additionally, vehicles 24 and 26 serve to protect vehicle 12 laterally and rearwardly. Also, a separation 36 exists between the vehicle 12 and the vehicle 26 .

In the second step S2, the vehicles 10 and 14 turn left, the vehicles 24 and 26 stop temporarily, and the main vehicle (vehicle 12) moves backward.

In a third step S3, the vehicles 10 and 14 are temporarily stopped to block the road 16 towards the front. Vehicle 26 is stationary and vehicle 24 is moving rearward in front of the primary vehicle, which forms a U-turn.

In a fourth step S4, the vehicles 10, 12, 14, 24 and 26 are moved in such a way that the convoy 18 has the form that the convoy 18 had in the first step S1, wherein, in a fourth step S4, the vehicle 24 is in the vehicle 10 , vehicle 26 is in the position of vehicle 14 , vehicle 14 is in the position of vehicle 24 , and vehicle 10 is in the position of vehicle 26 , such that a gap 36 now exists between vehicle 12 and vehicle 10 moving behind vehicle 12 . As can be seen from FIGS. 1 to 3 , the movement of vehicles 10 , 12 , 14 , 24 and 26 , especially during the second and third driving maneuvers, can be complex. However, since the vehicles 10, 12, 14, 24 and 26 receive telematics data, which can be transmitted, for example, visually and/or tactilely and/or acoustically to the respective driver, the driver can quickly and easily carry out the respective driving maneuver, and find their respective positions in convoy 18. In other words, by providing the vehicles 10 , 12 , 14 , 24 and 26 with information data, the drivers are not disoriented so that they can carry out their respective driving maneuvers without errors.
