EP1347425B1 - Method for the detection of vehicles driving against the traffic on motorways - Google Patents

Description

The invention relates to a method for detecting ghost drivers on at least one Roadway with a regular direction of travel, using a position detection system current position data of a vehicle are detected, on the basis of which it is checked whether when driving onto the road at least one predefined point, as a ghost point driver is called, is happening.

Furthermore, the invention relates to a traffic monitoring system for detecting ghost drivers on at least one lane with a regular direction of travel, which is set up by means of a position detection system current position data of a Vehicle to capture, and to check if driving on the road at least a predefined point, which is passed as a ghost driver point.

The term "ghost rider" is understood in this document to mean a vehicle which drives against a regular direction. The recognition of Ghost drivers comes a great importance in terms of traffic safety. In connection with the Recognition of Ghost drivers, some solutions have become known.

JP 07 260500 A describes a method or a system of the type mentioned. In this method, at intersections a turn in a wrong direction be determined. This is done using an angle between the current direction and the direction of travel associated with a one-way determines whether a vehicle is in the Concept is to go against a one-way. The disadvantage of this method is especially that it is not suitable for more complex topographical situations, such as motorway ramps there is the angle between the current direction of travel and one of the driveway permanently changing the assigned travel direction, resulting in incorrect results may have.

DE 299 15 718 U1 also describes a system for detecting ghost drivers which mounted in side strips of motorway exits or departures electronic Double or double sensors are attached. Are these sensors from a Drive through vehicle in the wrong order, so in this vehicle warning elements activated, z. B. flashing headlights, horn etc. This allows both the driver of in the wrong direction driving vehicle as well as oncoming vehicles warned become.

The disadvantage of this system is that it requires several sensors to arrange the driveways, as it is no longer possible in case of failure of a sensor, a to carry out correct supervision.

Another system for Geisterfahrererkennung is disclosed in DE 299 17 764 U1. at the known system is built into a vehicle, an induction receiver, wherein in Motorway entrances induction loops are provided. Drives a vehicle in wrong Direction of the highway, the induction receiver receives corresponding Signals, whereupon the ignition contact in the vehicle is interrupted. The restarting the vehicle can only by entering a special code, which of the police or another controlling body. The disadvantage of this system among other things, the need to dig in induction loops in the street.

It is therefore an object of the invention to provide a way which overcomes the disadvantages of overcomes known traffic surveillance systems.

This object is achieved by a method of the type mentioned in the invention solved by passing at least one further predefined, as a checkpoint designated point, by the vehicle on the basis of the position data certain order in which the ghost driver point and the checkpoint pass through be determined, whether the vehicle is driving in a direction that a ghost rider clearly identifies.

It is a merit of the invention without an installation of tools such as Sensors, on the route to a safe and efficient detection of ghost drivers guarantee.

In a variant of the invention, when passing at least one ghost driver point on the basis of an orientation determined at a distance from the ghost driving point Vehicle determines whether the vehicle is driving in a direction that uniquely identifies a ghost driver features.

Advantageously, at least one ghost driver point is in the area of a motorway ramp intended for each regular direction of travel.

Further advantages can be achieved by checking whether the vehicle is on Ghost driver is, in a first step when passing at least one Ghost Driver point at a distance after this point, the orientation of the vehicle is determined, and in a second step in passing the at least one further control point by the vehicle is ascertained the order in which the ghost driving point and the Checkpoint be passed.

In a further preferred embodiment of the invention, it is provided that a Alarm signal is generated when the vehicle is detected as a ghost driver, the Alarm signal displayed on the vehicle and / or a radio network to a Control body associated receiver or a Geisterfahrer- or toll system can be transmitted and issued.

Conveniently, the check is made whether the vehicle is a ghost rider aboard the Vehicle and / or in a specially provided external vehicle Geisterfahrerüberwachungszentrum.

Further advantages can be achieved by the position-finding system being satellite-supported and / or a terrestrial system and / or the position-finding system is an inertial navigation system.

For carrying out the method according to the invention, a traffic monitoring system is particularly suitable of the aforementioned type, which is adapted to, at Passing at least one further predefined point, called a checkpoint, by the vehicle, based on the position data to determine the order in which the Geisteifahrerpunkt and the checkpoint are driven through, as well as out of order the driving direction of the Ghost Driver Point and the Control Point Vehicle to determine.

In a variant of the invention, the traffic monitoring system is adapted to Passing at least one Ghost Driver Point on the basis of one at a distance determined by this point orientation of the vehicle to determine whether the vehicle in driving a direction that uniquely identifies a ghost rider.

Advantageously, at least one ghost driver point is in the area of a motorway ramp provided for each of the regular driving directions.

Further advantages can be achieved by the traffic monitoring system is set up to check whether the vehicle is a ghost driver, in a first Step by passing at least one Ghost Driver point at a distance after this Point to determine the orientation of the vehicle, and in a second step Passing the at least one further control point by the vehicle, the order determine where the Ghost Driver Point and Control Point pass become.

Furthermore, the traffic monitoring system may be configured to send an alarm signal generate when the vehicle is driving in the opposite direction, with it above may be configured to display the alarm signal on the vehicle and / or via a radio network to a recipient assigned to a control body or to transmit and output a ghost driver or toll central system.

Advantageously, the traffic monitoring system is set up to perform the verification, whether the vehicle is driving in a direction that uniquely identifies a ghost rider, on board the vehicle.

Conveniently, the position-finding system is satellite-based, and / or terrestrial, and / or an inertial navigation system.

The invention together with further advantages will be explained below with reference to a non-limiting embodiment, which is illustrated in the drawing. In this show schematically:

Fig. 1 shows an inventive traffic monitoring system and

Fig. 2 shows a sequence of the method according to the invention.

According to Fig. 1, an inventive traffic surveillance system is supported by a position-finding system, for example the so-called "Global Positioning System" short "GPS". In the case of the GPS system, on board a vehicle FAR a corresponding GPS module for determining position data to be provided. However, the invention is not limited to the GPS. In principle, the inventive method can be and the traffic monitoring system SYS according to the invention also with other known Realize position detection systems. For topographically difficult sections For example, so-called "Dedicated Short Range Communication" (short "DSRC") localization systems or inertial navigation systems. To the concept of the DSRC see, for example, DE 197 50 047 A1. Also inertial navigation systems are in large number became known. For example, EP 1 096 230 describes an inertial navigation system for vehicles, which together with a GPS system or in conjunction with another navigation system can be used to change the position of a Vehicle to determine. Likewise, the method according to the invention is applicable to other satellite and terrestrial positioning systems.

The direction of travel FRR of the vehicle FAR can be determined by the position determination system based on the temporal change in position of the vehicle FAR in a known per se can be determined - from successive positions of the vehicle FAR can be the Direction FRR, d. H. the current orientation of the vehicle FAR, clearly determine.

The calculation of the orientations of the vehicle FAR on the basis of the position data can be made in a control STR, for example a suitably programmed microprocessor, an arranged on board the vehicle FAR positioning unit PEH done. The Control STR may for this purpose be set up by the position detection system to receive time reference signals via a communication unit SEE and to calculate the position data from this. In the case of the GPS system, this orientation information becomes obtained together with the position data in the positioning unit PEH and made available. This case is hereafter without limitation of generality provided.

According to FIG. 2, two ghost driving points G1, G2 are provided, whose passing one Can trigger ghost driver detection. The coordinates of the Ghost Driver points G1, G2 are stored in a memory device of the positioning unit PEH, wherein The control STR can be checked to see if the current position of the vehicle FAR with a ghost point G1, G2 in the context of a likewise predetermined and stored Tolerance matches. Of course, checking if the vehicle is FAR a ghost driver is also outside the vehicle in a Geisterfahrerüberwachungszentrum not shown here take place, the current position data and the orientation of the vehicle FAR be transmitted to this ghost rider monitoring center have to. This transmission can take place via a radio network, for example a GSM network.

By definition of two "ghost driving points" G1, G2 per driveway UP (for semi-driveways also satisfies one) including associated Geisterfahrerorientierung O1, O1 in predetermined G1 or g2 G2 distances, only from a ghost rider and only in this Order can be passed (all others are "regular" cases), it is according to the invention with a small effort possible to trigger a ghost driver message. at The definitions of the orientations O1, O2 in the distances g1, g2 must not be ambiguous occur, i. the same value may be set in a monitoring area between G1, G2 and the entrance to the main road itself only occur once, which is caused by a suitable choice of the distances g1, g2 in which the orientations O1, O2 are measured, can be guaranteed. The following is the ghost driver detection just described referred to as "vectorial ghost driver detection".

Are the points G1, G2 in the regular direction of travel RF1, RF2, which in Fig. 2 through Arrows is indicated by defined on the main roadway additional control points K1, K2 followed, then another embodiment of the invention is possible, which in the Sequence is called "scalar ghost driver detection". Passes namely a vehicle FAR first the last point Gi and later a checkpoint Kj with i? J, then means that it is a ghost driver. For transits in the order (last) Gi => Ki are regular trips. Thus, the system can in the case i? j recognize that it is a ghost driver and the corresponding Trigger messages. A calculation of the orientations O1, O2 of the vehicle FAR is not required in this embodiment called "scalar ghost driver detection" However, this Geisterfahrer message takes place only after passing through the checkpoints Ki, so much later than in the case of the "vectorial ghost driver detection".

According to the invention, the two methods can also be conveniently combined to to increase reliability: triggers the vectorial procedure of a ghost driver any reason no message, then the vehicle can still Passing the checkpoints are recognized as ghost drivers. This procedure is beyond that also makes sense to get information about whether the ghost driver on the warnings from the message obtained by the vectorial procedure has reacted. Did he react, so at least he stopped or did he turn around and has driven back, then he should after passing a point Gi at the checkpoint Kj I can not even come up with i? j.

The inventive method is particularly simple in electronic vehicle toll systems integrate. Electronic vehicle toll systems, in which a Position determination, regardless of their design, provide information about the and departure of vehicles to or from a highway section. According to the invention can be derived from this information system-independent without significant overhead gain concrete directional parameters that allow statements about whether it to allowable (ie in the correct direction of travel) trips or just around Ghost rides (i.e., rides in the wrong direction).

• zu jeder Auffahrt werden 2 "Geisterfahrerpunkte" G1 und G2 durch ihre Koordinaten definiert (bei Halbauffahrten kann auch einer genügen)
• zu jedem Geisterfahrerpunkt G1 bzw. G2 werden in einem Abstand g1 bzw. g2 Geisterfahrer-Orientiemngen O1 bzw. O2 definiert. Eine Ermittlung der Geisterfahrer-Orientierung eines Fahrzeuges erfolgt nur, wenn das Fahrzeug die Geisterfahrerüberwachung durch Passieren von G1 bzw. G2 "scharf" gemacht hat. Die Geisterfahrer-Orientierungen O1 bzw. O2 sind so definiert, dass sie nur bei einem Geisterfahrer auftreten können. Wird nach Durchfahren des Punktes G1 bzw. G2 die zugehörige Geisterfahrer-Orientierung O1 bzw. O2 realisiert (nimmt also das Fahrzeug im Abstand g1 bzw. g2 diese nicht reguläre Orientierung ein), erfolgt eine "vektorielle" Auslösung einer Geisterfahrermeldung.
• Passiert das Fahrzeug nach vorherigem Durchfahren von G1 bzw. G2 auch noch einen Kontrollpunkt K2 bzw. K1, dann ist daran erkennbar (i≠j), dass es in der falschen Richtung fährt und es kann eine weitere "skalare" Geisterfahreralarmauslösung erfolgen.
• nach dem Passieren eines Kontrollpunktes K1 bzw. K2 können die Orientierungsermittlungen O1 im Abstand g1 vom Punkt G1 bzw. O2 im Abstand g2 vom Punkt G2 gelöscht werden.

In the following, the inventive method will be summarized again. The indices "1" and "2" always refer to the two possible directions of approach for a complete driveway; in a half-drive one of the two directions and thus one of the two points Gi, one of the two distances gi and one of the orientations Oi; however, two control points K1 and K2 must always be defined in order to be able to use the "scalar" operator signal message procedure:

• For each driveway, two "ghost riders points" G1 and G2 are defined by their coordinates (with half-rides one can also be enough)
• Ghost driver orientations O1 and O2 are defined at a distance g1 and g2, respectively, for each ghost driving point G1 or G2. A determination of the Geisterfahrer orientation of a vehicle takes place only if the vehicle has the Geisterfahrerüberwachung by passing G1 or G2 "sharp" made. The Ghost Driver Orientations O1 and O2 are defined so that they can occur only in a ghost driver. If, after passing through the point G1 or G2, the associated ghost-driver orientation O1 or O2 is realized (ie if the vehicle takes up this non-regular orientation at a distance g1 or g2), a "vectorial" triggering of a ghost driver message takes place.
• If the vehicle also passes a checkpoint K2 or K1 after passing through G1 or G2, then it can be seen (i ≠ j) that it is traveling in the wrong direction and another "scalar" ghost driver alarm triggering can take place.
• After passing a checkpoint K1 or K2, the orientation determinations O1 can be deleted at a distance g1 from the point G1 or O2 at a distance g2 from the point G2.
