Description

The The invention relates to a method for releasing or blocking a Area for a vehicle, an arrangement for release or blocking an area for a vehicle, a computer program and a computer program product.

State of the art

To the Preventing the passage of certain areas or areas in road traffic are conspicuous road markings, For example, white horizontal stripes on the road, or prohibition signs intended. These facilities only show the driver visually that a certain area may not be used. Other ways to prevent the danger are appropriate obstacles and therefore twill that the driver does not enable a specific area with his vehicle to drive. Examples of such physical closures are bollards or stones, the u. a. Walkways of streets separate.

in the Road traffic also become so-called variable message signs used, which are designed by providing a optical signal lanes, z. B. access roads of Cities to release in certain directions.

From the publication JP 2003/256993 a method for securing a route of a special or emergency vehicle is known. In this case, information about the planned route is sent to a control center by the special or emergency vehicle. This information is in turn forwarded from the control center and can be received by conventional vehicles. If a conventional vehicle should cross the planned route, its driver can be warned.

A similar process is in the document US 6,700,504 described. In this case, a route to be traveled by an emergency vehicle is calculated with the aid of a navigation system. Information about the calculated route is transmitted directly to other road users.

The publication KR 2003/096891 discloses a method in which emergency vehicles provide wireless communication information to other vehicles over an operational route.

In contrast, according to the in the document US 2006/244633 A1 Prior art disclosed a driver of a special or emergency vehicle on the positions of other, conventional vehicle information along its route and possibly warned.

A method for evacuating vehicles from a danger area is the subject of the document US 2007/198168 A1 , Here, the vehicles are located via signal exchange. A route for performing the evacuation is determined based on a home position of a vehicle.

A method for operating a system that includes automatically moving vehicles is from the document JP 11/143537 known. These vehicles are intended for the transport of goods in a factory or a department store. Each vehicle has a unit that indicates whether the vehicle is in standby mode. If a first vehicle should be in stand-by mode, it may move out of the way of another vehicle so as not to obstruct it.

Disclosure of the invention

The The invention relates to a method for releasing or blocking a Area for a vehicle in which one in the vehicle arranged control device wirelessly transmitted data The data informs if the area is released or is locked.

By Use of the data, the information about whether the area or an area is enabled or disabled, will clearly indicate if the area with the vehicle may be driven or not. This is done in the context of the procedure by a virtual marking of the area using the data. The data provided in the process is typical machine readable. A blocking or release of the area can at any time done dynamically. The corresponding information can the Control device and thus indirectly the driver of the vehicle be provided so that changed to a possibly abruptly Situation with regard to trafficability of the area can.

The mentioned data can u. a. from a communication module an infrastructure facility are transmitted, wherein the infrastructure facility data on whether the lane to lock or release, typically from at least one central Device, eg. A traffic control center, are provided. A blocking of the area may be dependent on an event, if the area passes through at least one device that has a higher Having priority to using the area as the vehicle respectively.

In one variant of the method, the area usually becomes a lane in traffic Depending on the direction of travel, it is enabled or disabled. This may mean that the area and thus the lane for vehicles that are designed as special vehicles, is released or locked. If the lane is cleared for at least one device designed as a special vehicle, the area for conventional vehicles can be locked. If the area is not used by the special vehicle, this can be released for the conventional vehicles. In one variant, the area or lane can be enabled or disabled depending on a time of day. Alternatively or additionally, the lane can be released or blocked depending on a traffic volume.

In a further embodiment of the invention can as a range Block area to be released or blocked. At a Locked area can also be a section of a Road and thus a part of public road traffic act. The procedure can, however, also for areas or Areas outside the traffic be applied. As a blocking area can, for example, a place or Walkway beside a road and / or also an area of a Land, for example, an airport, locked or released become. With the invention can u. a. on a parking or holding ban be noted for the area.

ever according to use case can be a certain area for which the procedure is carried out as a lane or as Sperrfläche be designated. The area can be dependent of whether the area is covered by a device, for example a special vehicle, that in the case of an airport be designed as an airplane can, is used, released or blocked.

to Further implementation of the procedure may be the driver of the vehicle the control device visually and / or acoustically pointed out be whether the area is released for his vehicle or Is blocked. In this case, the control device has a suitable one optical and / or acoustic display or information module on which is trained, the driver on one for the area respectively to point out the prevailing situation. It is also possible, that the control device with a described display or Hint module at least cooperates.

The Control device may alternatively or additionally with cooperate with at least one drive module of the vehicle, wherein a journey or onward journey taking into account the If the area is enabled or disabled, allowed or is prevented, wherein the at least one drive module of the Control device is affected. This also means that driving commands of the Driver who, by operating at least one control module, For example, the steering wheel or a pedal for braking, clutching or Gas input can be designed to be provided, influenced can be. In this way, movement commands, d. H. Steering commands, brake commands or throttle commands at least tlw. modified and possibly suppressed, so that in the context of the process an intervention in an operation of the vehicle provided by the driver is made.

There the one to the locked or released areas in a variant data provided by the method are machine-readable, information, including this data, collected by the control body and for the suppression and / or influence of the display or notification module be used so that the driver of the vehicle over a locked or released area is informed. It is also possible, usually machine-readable Data for influencing and / or influencing the operating module and / or drive module of the vehicle to use. Thus, under Considering the data an active intervention in one Operation of the vehicle to be made, for example, a driving a locked area is prevented.

If the vehicle has a communication module can be monitored with the method whether an area locked to the vehicle, of which Vehicle is driven. In such a case, the control device by sending a message or a warning Failure to comply with the terms of use of the area become.

By The infrastructure facility can be used for certain vehicles locked area sensory monitored and checked be whether the requirements for a use of the range of users or Drivers of vehicles are implemented. If an area that should be locked, yet is used, which means that the Driver drives the area with his vehicle or that the driver turns off his vehicle in the area can from the infrastructure facility sent warning information to the control facility will. In addition, a central facility, eg. a traffic control center to be notified about that a vehicle is illegally staying in the area. So can possibly additional measures be taken, the other users, d. H. Road users or Vehicles that point out that surface in the area Area illegally detains a vehicle. It can furthermore measures are taken to remove the vehicle become.

The inventive arrangement for free Giving or blocking an area for a vehicle has at least one communication module, wherein this at least one communication module is adapted to wirelessly communicate data indicating whether the area is enabled or disabled and to provide a control device of the vehicle.

The at least one communication module can be carried out a communication to receive and / or provide the data and accordingly send or transmit. The arrangement can be at least a communication module for an infrastructure facility formed, which is adapted for wireless transmission of the data is. The at least one for the infrastructure facility provided communication module, however, can also be trained be to receive data. Alternatively or additionally the arrangement is arranged in the control device of a vehicle Communication module, which is adapted to the data to receive and / or to send.

In a variant is the control device in the vehicle to do so configured to interact with at least one drive module of the vehicle and a ride on and / or to the area under consideration the circumstance, whether the area is enabled or disabled by To allow influencing the at least one drive module or to prevent and thus active in an operating sequence of the vehicle intervene.

Alternatively or In addition, this information on blocked or open spaces also in the control device of the vehicle be filed. In this case, information about areas, which are defined as a restricted or open space, in the control device saved.

If that with the control device or a corresponding system equipped vehicle drives a restricted area, may be a warning to the driver and / or other road users be issued. A map representation of the different free ones or locked areas or zones is also conceivable. In a Another embodiment, the vehicle by the control device also automatically stopped and / or released in a for driving Be led area.

at a possible implementation of the invention may be to the driver when driving on restricted areas an indication or a warning be issued. Alternatively or in addition to a A warning is sent to the infrastructure facility, if a vehicle equipped with the control device the Sperrfläche travels. By one in one Variant of the invention provided use of the control device or a control and / or regulating device, which in the Vehicle is arranged and with at least one drive module of the Vehicle interacts, driving on restricted areas be actively prevented.

With The invention can be expensive conversions on roads and / or driveways, bspw. Bollards, markings, etc. are avoided. In addition, the restricted areas can be variable and possibly dynamically designed, this is, for example, for an apron of an airport. In addition, in comparison to a use of physical obstacles, eg. B. bollards, when active Preventing the passage of the restricted area on the vehicle no damage caused because the vehicle is usually by the control device when attempting to enter the restricted area is stopped regularly.

There in the context of the invention, a virtual and no physical or physical blocking of an area, for example a surface is still available, it is still possible to for special vehicles, eg of emergency services, such as fire brigade, Police or ambulance, a permission to drive on restricted areas granted.

existing Systems with physical obstacles and / or visual prohibition signs may be supplemented with embodiments of the invention.

at Non-use of lanes designed as special lanes are, through the corresponding special vehicles are the special lanes or lanes as needed in one direction at certain times for the use of conventional vehicles released by a traffic control center. Thus offers an implementation the procedure a supplement and / or alternative to variable message signs, include the adjustable lights or traffic lights and visually show which lane is currently free or in which direction Is blocked.

With The invention is u. a. possible on expensive variable message signs, like, for example, traffic lights, to do without. Furthermore, a flexible Adjustment of trained as lanes areas at the prevailing Traffic flow possible. So can be in employment in the morning as areas three lanes into and out of town a track will be released out of town, then in the evening the reverse rule provided. Consequently, better utilization the traffic area are realized, since no special lanes unused stay.

In Design are lanes designed as special lanes, z. B. bus lanes, taxi lanes, motorway side strips, etc. of a Traffic control center via I2C (infrastructure-to-car) communication, providing a wireless exchange of data or information between the infrastructure and at least one vehicle, temporarily released or locked. The release can be automatic if no authorized special purpose vehicle, d. H. Bus, train, Taxi, etc., the lane needed. The position or location of this Special vehicles can communicate via C2X communication, i. H. through communication between a vehicle and any one be monitored by the traffic control center. The location may determine when to release a lane or close. Likewise, the functionality of variable message signs to enable or direction for lanes completely through the C2X communication, for an exchange of data between vehicles as well Vehicles and infrastructure facilities is replaced become. With existing C2X equipment for vehicles, with which the C2X communication can be executed the costs for variable message signs are saved.

In A vehicle is usually a suitable option to display the information provided in the process or data available, this may be a head-up display, to display information in a field of view of a farmer is formed, a screen, etc. act.

A further possibility for implementing the method exists in that the traffic control center informs about the special vehicles uses the possibly existing variable message signs head for. This can be public tracks be temporarily locked for special vehicles.

The Invention allows reserved lanes, z. B. Bus lanes, taxi lanes, motorway side strips, etc., or lanes generally as needed for one of the two Directions by using the I2C communication temporarily and flexible release.

at An airport can, for example, be an aircraft route (Runway) are blocked by applying the invention as an area, resulting in a significant increase in security level concerning accidents with vehicles and rolling Airplanes can be reached. By providing variable Travel routes as shared areas is a more efficient utilization the runway and apron of the airport for service vehicles possible. This allows faster loading and / or unloading and services are performed on the aircraft, thereby there is a time and cost savings. One as a control center trained infrastructure facility can in a variant of the Procedure to be informed when a vehicle prohibited in a restricted zone or restricted area.

To an embodiment of the method, the control device of the vehicle, for example, by satellite-based position determination (GPS) to determine their own position and this with the transmitted or stored coordinates to a prohibited zone or area to compare. Such restricted zones can z. B. in one Map display. Leave the vehicle a permitted zone or area and travels a restricted zone, the driver is warned appropriately. About that In addition, an automatic intervention in a vehicle guidance the driver under the influence of at least one drive module and / or operating module of the vehicle. So can the vehicle be forcibly stopped or over an active steering in the allowed zone.

Regarding Example of application of the invention for areas At an airport, the control center may use certain sections of the runway, Apron or a taxiway for service vehicles release temporarily or dynamically. If all vehicles equipped with the control device or a comparable system are, the control center can assume that no vehicle located in the restricted area. If a vehicle still in a should be located locked zone, the control center is about it provided a hint. Alternatively or additionally with a vehicle intervention under the influence of at least one Drive module and / or at least one operating module of the vehicle prevents the restricted zone from being traveled.

The Invention allows previously defined and / or also to mark variably definable restricted areas or restricted zones and the control device of a vehicle and indicate the driver to warn if necessary. An interaction of the control device with various vehicle drive devices and thus at least a drive module, for example, the brake and / or steering, also allows an active prevention of the passage of the restricted areas. This can be high costs for towing or Fines are avoided and, moreover, the obstruction of rescue and emergency services.

One possible application is the general road traffic, where different barriers areas, fire driveways, unloading zones, etc. can be marked as areas. Due to the necessary nationwide infrastructure is an application of the invention in smaller closed traffic systems, ie in non-public road traffic, conceivable because, inter alia, the infrastructure facilities are easier to install there. In such traffic systems are often areas as very large drivable areas available, which may differ from conventional roads. For example. At airports, vehicles may only move on assigned areas. In this case, routes of various service vehicles (buses, baggage vehicles, so-called "Follow Me" vehicles, tank vehicles, towing or towing vehicles, etc.) can intersect within certain areas and there is a much higher risk of collision than in conventional, orderly road traffic. This is usually the case when airplanes also move in the areas. By means of a blocking or release of typically passable surfaces or areas provided in the context of the invention, said collision risk can be reduced. The data provided for blocking or releasing can be standardized with regard to their format, so that the data can be received and used by many road users or vehicles.

The described arrangement is adapted to all Perform steps of the presented method. there Individual steps of this procedure can also be done by individuals Components of the arrangement are performed.

Farther can functions of the arrangement or functions of individual Components of the arrangement can be implemented as steps of the method. Besides, it is possible that steps of the procedure as functions of individual components of the arrangement or as functions the arrangement can be realized.

The Invention further relates to a computer program with program code means, to perform all the steps of a described method, if the computer program on a computer or equivalent Arithmetic unit, in particular in an inventive Arrangement, is executed.

The Computer program product according to the invention with program code means, which are stored on a computer-readable medium, is to perform all steps of a described Process trained when the computer program on a computer or a corresponding computing unit, in particular in an inventive Arrangement, is executed.
