Abstract

The invention relates to a method for forming a tramline for sections of high traffic, in particular in a traffic jam, wherein in the section of the track the tram line (17) for passing at least one emergency vehicle (19) is formed in traffic obstructions. In a method in which the formation of the alley proceeds in an ordered manner, a first vehicle (1, 7) detects the subsequent emergency vehicle (19) or an oncoming vehicle based on vehicle sensors and initiates an evasive movement, wherein information about the recognition the emergency vehicle (19) or the oncoming vehicle is successively forwarded from one vehicle (1, 7) to the next vehicle (3, 9) and the information is accompanied by an indication of the initiated evasive movement of the information transmitting vehicle (1, 7), on the basis of which the information receiving vehicle (3, 9) derives its own evasive movement.

Description

The invention relates to a method for forming a driving lane in sections of high traffic volume, in particular in a traffic jam, wherein in the section the lane is formed for passing at least one emergency vehicle in traffic.

From the DE 10 2012 211 568 A1 A method of forming a rescue lane is known in which accident information is sent from the injured vehicle after an accident, which is received by a vehicle closest to the accident vehicle via a communication interface, the vehicle receiving the accident information executing an accident response measure and the information via the accident response measure simultaneously to a plurality of vehicles and additionally or alternatively to a network, so that the plurality of vehicles forms an escape route.

Once a high volume of traffic, e.g. on highways or on construction sites and accidents, the likelihood of a traffic jam increases. Rescue vehicles have to pass the traffic jam and make their way through the traffic jam. Here, the evasive maneuvers of the vehicles, which are to form the rescue lane, done uncoordinated, which is why the rescue vehicle advances only very slowly.

The object of the invention is to provide a method for forming a tram, in which emergency vehicles can get to the accident center of gravity quickly and without much disability.

The invention results from the features of the independent claims. Advantageous developments and refinements are the subject of the dependent claims. Other features, applications and advantages of the invention will become apparent from the following description, as well as the explanation of embodiments of the invention, which are illustrated in the figures.

The object is achieved with a method in that a first vehicle using on-board sensors detects the subsequent emergency vehicle or an oncoming vehicle and initiates an evasive movement, wherein information about the detection of the emergency vehicle or the oncoming vehicle is successively forwarded from one vehicle to the next and the information is attached an indication of the initiated evasive movement of the vehicle emitting the information, on the basis of which the information receiving vehicle derives its own evasive movement. This has the advantage that a route for rescue vehicles and oncoming vehicles is cleared by a fleet evasive movement, in which the information is passed from one vehicle to another. This fleet evasive movement is triggered by a vehicle which detects the situation first. Thus, an uncoordinated evasion, which often happens too late or too slow, bypassed. Rescue vehicles arrive at their destination faster and the evasive maneuver becomes less dangerous, preventing secondary accidents.

In one embodiment, the first vehicle forwards information about the recognition of the emergency vehicle or the oncoming vehicle and the initiated evasive movement to the immediately next second vehicle, which performs the evasive movement corresponding to the first vehicle depending on its local position to the first vehicle and to a immediately following next third vehicle forwards the information about the detection of the emergency vehicle or the oncoming vehicle and the compensation movement of the second vehicle. This results in an orderly and fast provision of the tram.

Advantageously, the information between the vehicles is forwarded through a car-to-car communication. In such a car-to-car communication, each vehicle has a communication interface with which signals from another vehicle can be received and sent to another vehicle. This allows a direct and fast connection between the vehicles.

In an alternative, the information between the vehicles is transmitted by acoustic and / or optical signals. Such acoustic signals are generated by the vehicle horn, while optical signals are realized by the flashing or hazard warning lights. Since these systems are included in each vehicle, the corresponding information can be forwarded without problems from vehicle to vehicle.

In one variant, the second vehicle detects its local position to the first vehicle with at least one vehicle-own sensor. As a result, it is possible to dispense with additional sensors for realizing the method, which reduces the costs for carrying out the method.

In a development, the second vehicle performs depending on its position first vehicle, the same evasive movement as the first vehicle when the information-issuing vehicle is in front of or behind the vehicle receiving the information and a contrary evasive movement when the information-emitting vehicle is adjacent to the information-receiving vehicle. This ensures that secondary accidents are reliably prevented by driving due to various reactions during evasive maneuvers.

In one embodiment, the evasive movement of the vehicles is automatically generated upon receipt of the message. This is advantageously done by driver assistance systems that evaluate the information of the previous vehicle and initiate the evasive movement according to an evasive strategy. A partially, fully or fully automatic driver assistance system uses image and detection systems, such as a camera, a radar sensor, a lidar sensor or an ultrasonic sensor for estimating the environment, in particular for determining whether there is sufficient space for an evasive movement. In this case, existing parking assistance systems that have such sensors can be used, in which the process only has to be initialized or the driver must be supported or the driver only has to monitor or the driver no longer has to act.

In an alternative, the evasive movement of the vehicles is performed manually, after receiving the information automatically a steering proposal is generated. About this steering proposal, the driver of the vehicle receives an indication in which direction he should advantageously move his vehicle, so that the corresponding driving lane forms between the vehicles.

In one embodiment, the steering proposal is generated via a slight steering torque in a predetermined direction of travel. Thus, the driver receives a haptic information about the steering wheel, in which direction he should strike the steering wheel. Alternatively or additionally, the information can also take the form of a visual stimulus, such as an arrow

Advantageously, a GPS sensor and / or a radar sensor and / or a lidar sensor are used as vehicle-specific sensors for detecting the emergency vehicle or the oncoming vehicle or the local position for the information-emitting vehicle.

Alternatively, an e-call signal of one of the crashed vehicles serves as a signal for informing the vehicles about the accident. The signal received by the vehicles results in a visual, audible and / or haptic request to generate an emergency lane and initiates an evasion maneuver in the vehicle by orienting it with its sensor system on the vehicle in front. Thus, all vehicles follow the behavior of the first vehicle. This first vehicle has received the same visual, acoustic and / or haptic request, wherein the person driving in the first vehicle allows the formation of an emergency lane.

Further advantages, features and details will become apparent from the following description in which - where appropriate, with reference to the drawings - at least one embodiment is described in detail. Described and / or illustrated features may form the subject of the invention itself or in any meaningful combination, optionally also independent of the claims, and in particular may also be the subject of one or more separate application / s. The same, similar and / or functionally identical parts are provided with the same reference numerals.

It shows:

1 an embodiment of the inventive method.

In 1 an embodiment of the method according to the invention is shown in which vehicles 1 . 3 . 5 . 7 . 9 . 11 On a two-lane highway in a traffic jam, as the highway due to an accident from the vehicles 13 . 15 is blocked. An emergency vehicle 19 in the form of an ambulance needed a tram 17 through the vehicles to get to the accident site ( 1a ).

The vehicles 1 and 7 take the emergency vehicle 19 first by means of on-board sensors true, the on-board sensors represent, for example, a microphone that detects the ambient noise or a communication interface for a car-to-car communication, in which the emergency vehicle 19 gives out an information that it needs space. The vehicles 1 and 7 initiate an evasive movement, whereby the vehicle 1 in the direction of travel to the left to the roadside and the vehicle 7 moved to the right. At the same time the vehicle communicates 1 the warning message that an emergency vehicle 19 through want and his evasive movement to the vehicle standing in front of him 3 , This vehicle 3 detected with a GPS sensor, in which direction the vehicle 1 has evaded and makes according to a specified evasion strategy, an equal evasive movement to the emergency vehicle 19 pass. The vehicle 3 gives the appropriate Information to the vehicle 5 from standing in front of him and at the same time telling him next to the warning message, in which direction it will perform an evasive movement ( 1b ). The same thing is done by the vehicle 7 which is attached to the vehicle in front of him 9 also passes on the warning information and the information about the direction of the evasive movement. Also the vehicle 11 determines his position to the vehicle 9 , which has forwarded the warning information to them and performs an evasive movement. Because of this coordinated, column-like evasion of the vehicles involved 1 . 3 . 5 . 7 . 9 . 11 it will, as in 1c shown, allows a rescue lane 17 for the emergency vehicle 19 to accomplish.

The prescribed procedure does not only work for traffic jams 1 . 3 . 5 . 7 . 9 . 11 in which the rescue vehicle 19 approaching from behind, but it is also functional when moving vehicles, unplanned approaching a vehicle from the front or the side. In the case of a "ghost driver", a "wrong-way driver" or animals or people on the road, it is thus possible to avoid a large number of vehicles without problems. In an accident, the vehicles can also dodge swirling vehicle parts in this fleet movement. In addition, cross-traffic can also be stopped, warned or otherwise influenced by car-to-car communication. An operating and display concept for "ghost driver" and rescue vehicles in the vehicle indicates the direction of the "ghost driver" and proposes a fallback position and an avoidance direction.

If there is no easy avoidance due to the traffic situation due to a dense and halting traffic, the road condition and / or road construction possible, the information is transported from vehicle to vehicle until a vehicle is able to implement the alternative. Due to the first evasive maneuver now offers the opportunity for other vehicles to evade, and the initiation of the entire fleet movement has begun.

Although the invention has been further illustrated and explained in detail by way of preferred embodiments, the invention is not limited by the disclosed examples, and other variations can be derived therefrom by those skilled in the art without departing from the scope of the invention. It is therefore clear that a multitude of possible variations exists. It is also to be understood that exemplified embodiments are really only examples that are not to be construed in any way as limiting the scope, applicability, or configuration of the invention. Rather, the foregoing description and description of the figures enable one skilled in the art to practice the exemplary embodiments, and those of skill in the knowledge of the disclosed inventive concept may make various changes, for example as to the function or arrangement of individual elements recited in an exemplary embodiment, without Protection area defined by the claims and their legal equivalents, such as further explanations in the description.
