Abstract

The method involves detecting current position data for a vehicle using a position detection system, using this to check whether by driving onto a road (FA1,FA2) at least one predefined driving point (G1,G2) will be passed, whereby the vehicle's direction of travel (R1,2) is determined after it passes a driving point, and checking whether the vehicle is traveling in a direction positively identifying a wrong-way driver. AN Independent claim is also included for the following: a traffic monitoring system.

Description

The invention relates to a method for detecting ghost drivers on at least one Road with a regular direction of travel.

The invention further relates to a traffic monitoring system for the detection of ghost drivers on at least one lane with a regular direction of travel.

In this document, the term ghost driver is understood to mean a vehicle which runs against a regular direction of travel. The recognition of ghost drivers comes of great importance with regard to traffic safety. In connection with the Detection of ghost drivers some solutions have become known.

For example, DE 299 15 718 U1 describes a system of the type mentioned at the beginning, in which in Electronic double direction finder attached to the verge of motorway exits and exits or double sensors are attached. Are these sensors in a vehicle driving through the wrong order, warning elements are activated in this vehicle, e.g. B. flashing headlights, horn, etc. This can both the driver of the wrong Be warned in the direction of the moving vehicle as well as oncoming vehicles.

One disadvantage of this system is that several sensors are required to arrange the driveways, since it is no longer possible if a sensor fails, one perform correct monitoring.

Another system of the type mentioned is disclosed in DE 299 17 764 U1. at the known system, an induction receiver is installed in a vehicle, wherein in Motorway driveways induction loops are provided. Driving a vehicle in wrong Towards the freeway, the induction receiver receives the corresponding one Signals, whereupon the ignition contact in the vehicle is interrupted. The restart The vehicle can only be entered by entering a special code that the police or another control body is known. The disadvantage of this system is among other things, the need to dig induction loops in the street.

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

This object is achieved according to the invention with a method of the type mentioned at the outset solved in that by means of a position determination system current position data of a Vehicle are detected, which is used to check whether when driving onto the road at least one predefined ghost driver point is passed, and after passing this The driving direction of the vehicle is determined based on the position of the ghost driver is then checked whether the vehicle is traveling in a direction that a ghost driver clearly identifies.

It is a merit of the invention without the installation of tools such as Sensors to reliably and efficiently identify ghost drivers along the route guarantee.

In a variant of the invention, when passing at least one ghost driver point and at least one further control point by the vehicle on the basis of the Position data determines the order in which the ghost driver point and the control point drive through, determines whether the vehicle is traveling in a direction that one Clearly identifies ghost drivers.

In a further variant of the invention, when passing at least one ghost driver point based on an orientation determined at a distance after the ghost driver point of the vehicle determines whether the vehicle is traveling in a direction that a ghost driver clearly identifies.

Advantageously, there is at least one ghost driver point in the area of a freeway entrance intended for every regular direction of travel.

Further advantages can be achieved by checking whether the vehicle is a In a first step, passing ghost driver is at least one ghost driver point the orientation of the vehicle is determined at a distance after this point, and in a second step when passing through the at least one further checkpoint the vehicle determines the order in which the ghost driver point and the Be passed through the checkpoint.

In a further preferred embodiment of the invention it is provided that a Alarm signal is generated when the vehicle is recognized as a ghost driver, the Alarm signal shown on the vehicle and / or via a radio network to one Control body assigned receiver or a ghost driver or toll central system can be transmitted and output.

The check whether the vehicle is a ghost driver is advantageously carried out on board the Vehicle and / or in a specially provided vehicle driver ghost driver monitoring center.

Further advantages can be achieved if the position determination system is supported by satellites and / or is a terrestrial system and / or the position determination system is an inertial navigation system.

A traffic monitoring system is particularly suitable for carrying out the method according to the invention of the type mentioned at the outset, which is set up to current position data of a vehicle by means of a position determination system record, and check whether at least one ghost driver point when driving onto the road is passed, and after passing this ghost driver point based on the position data determine the direction of travel of the vehicle and check whether the vehicle drives in a direction that clearly identifies a ghost driver.

In a first variant of the invention, the traffic monitoring system according to the invention set up to pass at least one ghost driver point and at least another control point by the vehicle using the position data the order to determine in which the ghost driver point and the control point pass and check if the vehicle is traveling in a direction that is a ghost driver clearly identifies.

In a further variant of the invention, the traffic monitoring system is set up to when passing at least one ghost driver point using one at a distance after this point determined orientation of the vehicle to determine whether the vehicle drives in a direction that clearly identifies a ghost driver.

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

Additional advantages can be achieved by adding the traffic monitoring system is set up to check whether the vehicle is a ghost driver in a first Step when passing at least one ghost driver point at a distance after it Point to determine the orientation of the vehicle, and in a second step Passing the at least one further checkpoint through the vehicle the order determine in which the ghost driver point and the control point pass become.

Furthermore, the traffic monitoring system can be set up to send an alarm signal generate when the vehicle is traveling in the opposite direction of travel, being above it can also be set up to display the alarm signal on the vehicle and / or via a radio network to a receiver assigned to a control body or to transmit and issue a ghost driver or toll central system.

The traffic monitoring system is advantageously set up to check, whether the vehicle is traveling in a direction that clearly identifies a ghost driver, to be carried out on board the vehicle.

The position determination system is advantageously satellite-based and / or terrestrial, and / or an inertial navigation system.

The invention and further advantages are explained in more detail below with reference to a non-restrictive exemplary embodiment, which is illustrated in the drawing. This shows schematically:

1 shows a traffic monitoring system according to the invention and

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

1, a traffic monitoring system according to the invention is supported by a position determination system, for example the so-called "global positioning system" short "GPS". In the case of the GPS system, a corresponding FAR can be on board a vehicle GPS module can be provided for determining position data. However, the invention is not limited to the GPS. In principle, the method according to the invention can be used and the traffic monitoring system SYS according to the invention also with other known ones Realize position detection systems. For topographically difficult sections of the route So-called "Dedicated Short Range Communication" (short "DSRC") localization systems or inertial navigation systems. The concept of the DSRC see for example also DE 197 50 047 A1. Inertial navigation systems are also in large numbers became known. For example, EP 1 096 230 describes an inertial navigation system for vehicles, which together with a GPS system or in connection can be used with another navigation system to determine the position of a To determine the vehicle. The method according to the invention is also applicable to other satellite and terrestrial positioning systems are transferable.

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

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

According to FIG. 2, two ghost driver points G1, G2 are provided, one of which passes 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, whereby from the control STR can be checked whether the current position of the vehicle FAR with a ghost driver point G1, G2 within the scope of a likewise specified and stored Tolerance matches. Of course, checking whether the vehicle is FAR a ghost driver is also external to the vehicle in a ghost driver monitoring center, not shown here done, with the current position data and orientation of the vehicle FAR are transferred to this ghost driver monitoring center have to. This transmission can take place via a radio network, for example a GSM network.

By defining two "ghost driver points" G1, G2 per ascent OPEN at (half ascent a) including the associated ghost driver orientation 01, 01 is also sufficient Distances g1 from G1 or g2 from G2, only by a ghost driver and only in this Order can be passed (all others are "regular" cases), it is according to the invention possible to trigger a ghost driver report with little effort. at The definition of the orientations O1, O2 at the distances g1, g2 must not be ambiguous occur, i.e. the same value may be in a monitoring area between G1, G2 and the entrance to the main lane itself only occur once, which is caused by a suitable choice of the distances g1, g2 at 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 are shown in FIG Arrows are indicated from additional control points defined on the main lane K1, K2 followed, then another embodiment of the invention is possible, which in the Episode is referred to as "scalar ghost driver detection". Passes through a vehicle FAR means the last point Gi and later a control point Kj with i ≠ j, then means that it is a ghost driver. For passages in the order (last) Gi => Ki are trips in the regular direction. So the system in 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 is FAR not required in this embodiment, referred to as "scalar ghost driver detection", however, this ghost driver report only occurs after passing through the checkpoints Ki, significantly later than in the case of "vectorial ghost driver detection".

According to the invention, the two methods can also be suitably combined in order to to increase reliability: triggers the vectorial process for a ghost driver for some reason no message, then the vehicle can still contact Driving through the checkpoints are recognized as ghost drivers. This procedure is also useful to get information about whether the ghost driver to the warnings from the message obtained according to the vectorial procedure has reacted. If he reacted, he at least stopped or turned over and has returned, then after passing a point Gi at the checkpoint Kj with i ≠ j no longer come around.

The method according to the invention is particularly easy to implement in electronic vehicle toll systems integrate. Electronic vehicle toll systems, one of which Position determination is carried out, regardless of their design provide information about and departure of vehicles to or from a highway section. According to the invention can be made system independent from this information without significant additional effort gain specific direction-dependent parameters that allow statements about whether it is about permissible journeys (namely in the correct direction of travel) or just Ghost journeys (i.e. journeys 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-Orientierungen 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.

The method according to the invention is to be summarized again below. The indices "1" and "2" always refer to the two possible directions of ascent for a complete ascent; in the case of a half-way up one of the two directions is omitted and thus generally 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" ghost driver report method:

• For each ascent, 2 "ghost driver points" G1 and G2 are defined by their coordinates (one can be sufficient for half ascents)
• to each ghost driver point G1 or G2 at a distance g1 or g2 ghost driver orientations O1 or O2 are defined. The ghost driver orientation of a vehicle is only determined if the vehicle has activated the ghost driver monitoring by passing G1 or G2. The ghost driver orientations O1 and O2 are defined so that they can only occur with a ghost driver. If the associated ghost driver orientation O1 or O2 is realized after passing through point G1 or G2 (ie the vehicle assumes this non-regular orientation at a distance g1 or g2), a "vectorial" triggering of a ghost driver message occurs.
• If the vehicle also passes a control point 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 a further "scalar" ghost driver alarm trigger can take place.
• after passing a control point K1 or K2, the orientation determinations O1 can be deleted at a distance g1 from point G1 or O2 at a distance g2 from point G2.
