Description

The present invention relates to a vehicle device according to the preamble of claim 1, a system according to the preamble of claim 10, a roadside device according to the preamble of claim 13 and method according to the preamble of claim 14.

For the purposes of toll collection in electronic toll collection systems, vehicles, so-called on-board units (OBU), are used today in vehicles, in particular in trucks.
These vehicle devices may be of the self-locating type and may include a position determining device which determines a position of the vehicle at a plurality of consecutive times, the positions determined by the vehicle device based on the determined positions by the vehicle device or by a central device located outside and away from the vehicle receives, is determined in the course of a comparison of positions with map data, whether the vehicle has traveled on a toll section. They may also be of the externally located type and comprise a vehicle-side communication device transmitting information about the identity of the vehicle device and / or the vehicle to a road-side communication device of a road-side survey device, which transmits this information with an identifier representative of a route section. the vehicle has passed in the course of the passage at the roadside communication device linked.
Instead of a position-determining device, self-locating type vehicle devices may also include a vehicle-side communication device which receives from a road-side communication device of a road-side survey device the identifier of a route section that the vehicle passes in the course of passage at the road-side communication device.
In each case of a specific, linked or received toll section depends on the toll section and optionally depending on predetermined, so-called toll-relevant vehicle data of the vehicle, such as the emission class, the vehicle weight, the number of axles, etc., a toll fee determined and this by Billing to a user of the vehicle and / or charged by debiting an account of a user of the vehicle.

In addition to the toll collection process, electronic toll collection systems have at least one "enforcement" process. For this purpose, both the vehicle devices of the self-locating type and those of the externally located type are equipped with a vehicle-side communication device which - if available - can be provided by the vehicle-side communication device that is used for toll collection. In the control process, a control device of the toll system located outside and outside the toll vehicle communicates with the vehicle-side communication device of the vehicle device by means of a control communication device and requests at least operating capability information from the vehicle device that affirms or unites the operability of the vehicle device. In addition, the vehicle device may be requested by the control device to transmit its identifier to the control device, the license plate and toll-relevant vehicle data of the toll vehicle to which it is associated, as well as data on the last communication with a roadside surveyor or the last determined section of the route.

There are various types of control devices: hand-held devices for stationary control of a stationary vehicle in the context of a stand control, control vehicles for mobile control of a moving vehicle (for example in the context of an overtaking process) and roadside control devices for stationary control of a moving vehicle (for example, the road spanning several arranged transversely to the direction of travel, each associated with a lane communication facilities).
The described road-side surveyors and road-side controllers can be grouped together under the concept of the roadside facility, or "beacon", on the basis of the roadside communications facilities that each comprise.

The vehicle-side communication device and the road-side communication device are preferably of the short-range communication type, allowing communication over at least 10 meters and up to 1000 meters between the vehicle-side communication device and the road-side communication device by radio or optical communication, preferably in the infrared region is. In particular, the short-distance communication according to a standard for short-distance communication, such as WAVE, W-LAN or DSRC (dedicated short-range communication). A standard for 5.8 GHz microwave frequency DSRC communication is EN 12253, for example.

A transaction is a sequence of program steps whose execution is triggered by a specific event and which ends with a defined result.
A communication transaction between a first and a second communication partner may in particular comprise the steps of data transmission and data reception. In particular, it includes the entire information exchange between the first and second communication partners necessary to arrive at the result of the transaction. Trigger of a communication transaction, for example, be the receipt of a sent by the first communication partner request signal by the second communication partner to perform the transaction. A result of a communication transaction may be, for example, that the first communication partner receives a requested by the request signal information from the second communication partner. At the conclusion of the communication transaction, for example, the first communication partner confirms by a message to the second communication partner that he has received the requested information.

In the case of the participation of a road-side surveyor in the toll collection is called a 'toll transaction as a special case of a communication transaction when in the vehicle device and / or the roadside survey device as a result of data exchange between the vehicle device and the roadside survey device by means of their respective communication devices (in particular DSRC). Communication devices) at least one assignment of a traveled route section (for example, its identifier) to the vehicle (for example, its characteristics) takes place. Equivalent mappings, such as a toll to the vehicle device (eg, its serial number or mobile number) or to a user (eg, its customer number) are also the result of such a toll transaction. Such a toll transaction is described by way of example in the form of the CARDME transaction in Annex B of the standard DIN EN ISO 14906, the contents of which are expressly referred to in the context of the present description.

In the case of participation of a control device in the control is called a control transaction as a special case of communication transaction, if at least the information in the roadside control device as a result of data exchange between the vehicle device and the roadside control device by means of their respective communication devices (in particular DSRC communication devices) which has requested the roadside control device of the vehicle equipment.

In general, any transaction in which a roadside facility is involved with a roadside communication facility may also talk about a bakery transaction.

Both in the survey case and in the control case, the vehicle facility can inform about the successful or unsuccessful execution of the transaction and / or be informed, for example by an acknowledgment message ("receipt"), and register the transaction as performed or not performed based on this information.

Having said this, the problem of repeatedly executing a transaction occurs when, after performing a first transaction between the vehicle device and a roadside device, a second transaction occurs between the same vehicle device and the same roadside device, for example, because the vehicle is after performing the first Transaction did not move fast enough out of the communication area with the roadside facility.
In the case of a toll transaction, this would mean that a toll will again be charged to the vehicle for the same section of the route. Although such a double entry may be reversed by a time comparison of timestamps associated with the respective transaction, for example by deleting the transaction result of the second transaction, if the time difference between the second timestamp of the second transaction and the first timestamp of the first transaction is a predetermined maximum time difference, does not exceed. However, with larger time differences, such as may occur in the event of a jam holding the vehicle in the communication area with the roadside device for more than one hour, the problem arises that the predetermined maximum time difference can not be increased beyond the time period. a vehicle needs at best, after a first passage of the communication area with the roadside facility to re-enter this communication area in the course of a second passage.

To remedy this problem, the inventor has taken on the task of further developing a vehicle device according to the preamble of claim 1, a system according to the preamble of claim 10, a roadside device according to the preamble of claim 13 and a method according to the preamble of claim 14 that in particular the already mentioned double booking is avoided.

Advantageous developments are the subject of dependent claims, with advantageous developments and features of embodiments of independent claims and their effects and advantages as transferable to other independent claims apply, as far as this is possible without contradiction and technically feasible.

According to a first aspect of the invention, a vehicle device is provided for carrying out at least one transaction by means of or in communication with a roadside device, wherein the vehicle device is adapted to detect a first location information, performing a first transaction by means of or as a result of communication with a first roadside means to detect at least a second location information, to allow the performance of a second transaction subsequent to the first transaction when the location information difference between the first location information and the second location information exceeds a predetermined difference amount, and to perform a second transaction subsequent in time to the first transaction not allow if the location information difference between the first location information and the second location information has a predetermined Un the amount of the difference.

By choosing a correspondingly large difference in a system having a vehicle device according to the invention and a first roadside device, it is thus advantageously possible to avoid a second transaction taking place within a first communication zone of the first roadside device by means of or as a result of communication of the vehicle device with the first roadside device , Preferably, the difference is greater than the length of the first communication zone of the first roadside device in the flow direction of intended traffic of vehicles, at least one of which has the vehicle device according to the invention. Preferably, in a system comprising the in-vehicle device according to the invention, a first roadside device and at least one second roadside device, the difference is smaller than the distance of a second roadside device next in the traffic flow direction of the first roadside device to the first roadside device. For example, the difference is greater than 50 meters and less than 2000 meters. Nonetheless, in a system including the in-vehicle device, a first roadside device, a second roadside device, and at least a third roadside device, the difference amount may be larger than the distance of a second roadside device next in the traffic flow direction of the first roadside device to the first roadside device and smaller be the distance of a third roadside device overflowing in the traffic flow direction of the first roadside device. Thus, a transaction can be selectively avoided in interaction with the second roadside device arranged between the first and third roadside devices.

The detection of location information by the vehicle device according to the invention comprises both the determination of a position as absolute location information by the vehicle device, for example by means of a GNSS position determination device comprised by the vehicle device on the basis of received signals from satellites of a Global Navigation Satellite System (GNSS), as well as the determination of a path length as a relative location information by the vehicle device, for example by means of a Weglängenmesseinrichtung included in the vehicle device, as well as the receipt of a location information or position of a roadside device by means of a communication device of the vehicle device, a position of the roadside device is considered as sufficiently accurate to the position of the vehicle device accordingly ,
The reception of a position is particularly important in cases in which due to shading effects - for example in a tunnel - in the absence of received GNSS signals, the determination of a position is not possible. So can - for example, at a distance of some 10 to a few 100 meters in a tunnel at the Tunnel ceiling or wall beacons each emitting their position repeatedly at intervals of a few milliseconds.
On the other hand, the roadside device with which the vehicle device communicates for carrying out the transaction can also send its location within the scope of a signal sent to the vehicle device (for example the request signal) which the vehicle device receives and records as a separate position.

Thus, on the one hand, the vehicle device according to the invention may comprise a position determination device, the first and second location information may be absolute location information in the form of first and second positions, and the vehicle device according to the invention may be configured to receive the first position and the second position from the position determination device or by means of the position determination device determine to allow the execution of the second transaction when the distance between the second position and the first position exceeds a predetermined first limit distance and not to permit the execution of the second transaction when the distance between the second position and the first position exceeds the predetermined first Limit distance does not exceed.
Such a vehicle device does not necessarily have to include a path length measuring device.
Such a vehicle device may include a GNSS position determination device that is configured to receive navigation signals from navigation satellites of a global navigation satellite system (GNSS) and to determine positions based on the received navigation signals, wherein the vehicle device is configured to transmit the first and the second position from the GNSS device. Position determining device to receive or to determine by means of the position determination device.

On the other hand, the vehicle device according to the invention may comprise a path length measuring device, the first and second location information may be relative location information in the form of first and second path lengths, and the vehicle device may be configured to receive the first path length and the second path length from the path length measuring device or to determine it by means of the path length measuring device to allow the execution of the second transaction when the difference between the second path length and the first path length exceeds a predetermined first limit difference, and not to permit the execution of the second transaction if the difference between the second path length and the first path length does not satisfy the predetermined first limit difference exceeds. Such a vehicle device does not necessarily have to include a position-determining device.

On the other hand, the in-vehicle device according to the present invention may be configured to receive the first location information from the first roadside facility, receive the second location information from the first roadside facility, or from a second roadside facility to allow the second transaction to be performed if the second location information does not coincide the first location information, and not to allow the execution of the second transaction when the second location information matches the first location information. Such a vehicle device does not necessarily comprise a position determination device or a path length measurement device.

In particular, the location information difference between the first location information and the second location information, as well as the predetermined difference amount, is an amount, i. H. positive, value. To this extent, the location information difference can also be referred to as location information difference amount.

The predetermined difference amount can be fixed. Preferably it is greater than 50 meters and less than 2000 meters. For example, it is 250 meters.
The predetermined difference amount can each be stored in the vehicle device linked to a beacon geo object, which determines the vehicle device by comparison with a position detected in connection with the execution of the first transaction (for example the first location information in the form of a first position). Thus, a device-specific difference amount is available for each road-side device, which is determined in each case as a function of the transaction by the vehicle device as a predetermined difference amount.
The predetermined difference amount may be stored in the roadside device and sent by the roadside device and received by the vehicle device as part of a communication signal, in particular as part of an acknowledgment signal on the successful completion of the transaction. Also, there is a facility-individual difference amount for each street-side device, which is determined in each case as a function of the transaction by the vehicle device as a predetermined difference amount.

In particular, at least the first roadside device of a system comprising the vehicle device according to the invention and a first roadside device is designed as a road bridge spanning a first roadside communication device (in particular a first roadside DSRC communication device) for transaction-related communication with a communication device (in particular a DSRC) DSRC communication device on the vehicle side) of the vehicle device or on which a first roadside communication device for transaction-related communication with a communication device (in particular a vehicle-side DSRC communication device) of the vehicle device is mounted.
Optionally, the second roadside device of a system including the vehicle device according to the invention, the first roadside device, and at least one second roadside device is configured as a second bridge bridging the road, the second roadside communication device (in particular a second DSRC roadside communication device) being transaction-dependent Communication with a communication device (in particular a vehicle-side DSRC communication device) comprises the vehicle device or to which a second roadside communication device (in particular a second roadside DSRC communication device) for transaction-related communication with a communication device (in particular a vehicle-side DSRC communication device) of the vehicle device is mounted.

Alternatively, in particular, at least the first roadside device of a system comprising the vehicle device according to the invention and a first roadside device is configured as a first pillar arranged at a distance of one to 20 meters beside the road, comprising a first roadside communication device (in particular a first DSRC roadside communication device ) for transaction-related communication with a communication device (in particular a vehicle-side DSRC communication device) of Vehicle device comprises or at the one of the first roadside communication device (in particular a first roadside DSRC communication device) for transaction-related communication with a communication device (in particular a vehicle-side DSRC communication device) of the vehicle device is attached.
Optionally, the second road-side device of a system comprising the vehicle device according to the invention, the first roadside device and at least one second roadside device is also configured as a second pillar arranged at a distance of one to 20 meters next to the road, comprising a second roadside communication device (in particular a second road-side DSRC communication device) for transaction-dependent communication with a communication device (in particular a vehicle-side DSRC communication device) of the vehicle device or at the second roadside communication device (in particular a second roadside DSRC communication device) for transactional communication with that of a communication device (in particular a vehicle-mounted DSRC communication device).

The difference between a transaction carried out by means of a communication between a vehicle device and a roadside device, and a transaction made as a result of communication between a vehicle device and a roadside device, is that in a transaction performed by means of a transaction Communication between a vehicle device and a roadside device is carried out, at least a certain communication between the vehicle device and a roadside device is sufficient condition for the execution of the transaction in the sense that the reception of data transmitted by means of the particular communication is already considered a transaction During a transaction that is performed as a result of communication between a vehicle device and a roadside device, at least one particular communication zwis the vehicle facility and a roadside facility is only a necessary condition for carrying out the transaction in the sense that in addition to receiving data transmitted by the communication of at least one of the two communication partners, vehicle facility or roadside facility, perform at least one processing step on the received data must, so that it comes to the completion of the transaction.

Under a communication between a vehicle device and a roadside device can be understood both the unidirectional communication in which the roadside device only transmits and the vehicle device only receives or only transmits the vehicle device and the roadside device only receives, as well as any communication of bidirectional communication, in which both the roadside device sends and receives and transmits and receives the in-vehicle device.
In particular, the communication may consist of the transmission of a single message as part of a single communication signal. In such a message, therefore, all the information is included in the form of all the data that the receiver needs in order for the transaction to be valid or to be performed upon receipt of the communication signal by the receiver. For example, this communication is formed by the transmission and reception of an initialization signal that the roadside device sends and receives the vehicle device or transmits the vehicle device and receives the roadside device. Alternatively, the communication may involve the transmission of multiple messages as part of multiple communication signals which are sent from the vehicle device to the roadside device and received by the roadside device and sent by the roadside device and received by the vehicle device.
Such communication may be initialized by the transmission of an initialization signal by the vehicle device or by the roadside device.
The vehicle device according to the invention is preferably designed to transmit and / or to receive the communication with a road-side device forming or initializing initialization signals.

Preferably, the in-vehicle device according to the invention is arranged to allow the first transaction to be carried out by, by or through first communication with a first roadside facility for performing the first transaction, allowing the second transaction subsequent in time to the first transaction to be performed by or as a result of communicating with the first roadside device or second roadside device to perform the second transaction and not allowing the second transaction to be timed following the first transaction by neither using nor following communication with the first roadside to avoid the second transaction Device or a second roadside device for performing the second transaction contributes.
For example, such a vehicle device may be configured to send and / or receive the communication with a roadside device forming or initializing initialization signals.
For example, such a vehicle device may be configured to contribute to the execution of the first transaction by transmitting a first initialization signal or by receiving a first initialization signal transmitted from the first roadside device or by receiving and processing a first initialization signal transmitted by the first roadside device by transmitting a second initialization signal or by receiving a second initialization signal transmitted from the first roadside device or a second roadside device, or by receiving and processing a second initialization signal transmitted from the first roadside device or a second roadside device to perform the second Transaction, and by the omission of the transmission of a second initialization signal or by the Unterdrüc ken of receiving a second initialization signal transmitted from the first roadside device or a second roadside device or by omitting the processing of a second initialization signal sent from the first roadside device or a second roadside device and received by the vehicle device to prevent the second transaction from being performed.
Similarly, such a vehicle device may be configured to transmit a first information signal due to the receipt of a first initialization signal or a first response signal on a transmitted first initialization signal, to allow the second transaction to be performed by sending a second initialization signal or by receiving a second initialization signal second initialization signal sends a second information signal, and not to allow the execution of a second transaction, by not sending a second initialization signal sends, sends no second information signal and / or suppresses the reception of a second initialization signal or its processing.

A vehicle device according to the invention can also be configured to receive request signals from roadside devices, to contribute to the execution of the second transaction by transmitting a first information signal as a result of the receipt of a first request signal or a first response signal for a transmitted first initialization signal to carry out the first transaction; by sending a second information signal as a result of receiving a second request signal, and not allowing a second transaction to be carried out by not sending a second information signal and / or by suppressing the receipt of a second request signal or its processing.
Alternatively, the invented vehicle device may be configured to transmit presence signals, to contribute to the transmission of a first information signal as a result of receiving a first response signal on a transmitted first request signal for performing the first transaction, to allow the second transaction to be performed by sending a second initialization signal and not to allow a second transaction to be performed by not sending a second initialization signal.

For example, this detection time is a second detection time, which is temporally downstream of a first detection time of the first location information.
A detected location information is then used according to the invention as the first location information if it is included by determining its difference to the second location information in the decision whether a second transaction is allowed or not.
The first communication signal may be a first initialization signal that transmits the in-vehicle device or the first roadside device without previously receiving another communication signal from the first roadside device or vehicle device from which the first initialization signal is received. Alternatively, the first communication signal may be a first response signal that the vehicle device transmits in response to a first initialization signal transmitted by the first roadside device received by the vehicle device, or the first roadside device in response to a vehicle device sent by the first one roadside device receives received first initialization signal. Alternatively, the first communication signal may be a first acknowledgment signal that the vehicle device receives from the first roadside device or the first roadside device from the vehicle device without thereafter sending another communication signal to the first roadside device or the vehicle device.

For example, the first detection time is preceded by a second detection time at which the second location information is detected.

Detected location information is then used according to the invention as second location information if it is included in the decision as to whether a second transaction is to be admitted or not by determining its difference from the first location information.
The first communication signal may be a first initialization signal that transmits the in-vehicle device or the first roadside device without previously receiving another communication signal from the first roadside device or vehicle device from which the first initialization signal is received. Alternatively, the first communication signal may be a first response signal that the vehicle device transmits in response to a first initialization signal transmitted by the first roadside device received by the vehicle device, or the first roadside device in response to a vehicle device sent by the first one roadside device receives received first initialization signal. Alternatively, the first communication signal may be a first acknowledgment signal that the vehicle device receives from the first roadside device or the first roadside device from the vehicle device without thereafter sending another communication signal to the first roadside device or the vehicle device.

Preferably, the in-vehicle device according to the invention is designed to send at least one first communication signal to the first roadside device or to receive it from the first roadside device at the first roadside device for performing the first transaction, at a plurality of a first detection time point of the detection Following the first location information, detection times each to capture at least one location information and use of the multiple, recorded after the first detection time, location information detected location information as second location information, the detection time a second communication time of the upcoming broadcast or receiving a second communication signal by the vehicle device in time immediately preceding or whose location information difference to the first location information exceeds the predetermined difference amount tet.
The first communication signal may be a first initialization signal that transmits the in-vehicle device or the first roadside device without previously receiving another communication signal from the first roadside device or vehicle device from which the first initialization signal is received.

The invented vehicle device is preferably designed to register the execution of the first transaction and to carry out the detection of a second location information as a result of the registration of the execution of the first transaction. For example, the in-vehicle device may be configured to register the execution of the first transaction in the first roadside device by receiving a first acknowledgment signal from the first roadside device about the successful receipt of the information previously given to the first roadside device by the in-vehicle device sent the first transaction.
Particularly preferably, the vehicle device according to the invention is designed to register the execution of the first transaction at a first registration time, which precedes a second detection time of the second location information, and to carry out the detection of a second location information as a result of the registration of the execution of the first transaction.

Preferably, the invented vehicle device is designed to register the execution of the first transaction at a registration time and to not allow a second transaction during a predetermined prohibition period after the registration time of the first toll transaction. Preferably, the duration of the prohibition period is greater than 1 second and less than the travel time that a vehicle at least needs to maintain the speed limit to from the first communication area of the first roadside device in the second communication area of the second roadside device immediately following in the direction of travel on the road or re-enter the first communication area of the first roadside facility on the shortest regular path, depending on which of the two routes takes less travel time.

Preferably, the vehicle device according to the invention is designed to detect a plurality of second location information and to permit the execution of a second transaction subsequent to the first transaction when the location information difference between the first location information and a certain number of second location information exceeds a predetermined difference and the execution of one of the first transaction temporally subsequent second transaction, if the location information difference between the first location information and a certain number of second location information does not exceed a predetermined difference amount.
Thus, particularly in the case where the location information is absolute positions provided by a GNSS position determining means of the vehicle device, the reliability of the decision to perform or not to perform a second transaction can be increased. Because even at a standstill, the GNSS position determination has a larger position error than motion, and such a measure precludes that a single, due to a very large position error random difference exceeding the position difference of a second position to the first position leads to an unjustified second transaction. Preferably, the predetermined number is greater than two and less than ten. Particularly preferred is the predetermined number three, four or five.
The vehicle device according to the invention is particularly preferably designed to detect a plurality of second location information and to permit the execution of a second transaction subsequent to the first transaction if the location information difference between the first location information and a specific number of second location information acquired within a predetermined time frame exceeds a predetermined difference. and not allowing the execution of a second transaction subsequent to the first transaction if the location information difference between the first location information and a certain number of second location information acquired within a predetermined time frame does not exceed a predetermined difference. Thus, the reliability of the decision to perform or not to perform a second transaction can be further increased. Preferably, the predetermined number is greater than two and less than ten. Particularly preferred is the predetermined number three; four or five. Preferably, the predetermined time frame is greater than two seconds and less than ten seconds.

Thus, the reliability of the decision to perform or not to perform a second transaction can be further increased. Preferably, the predetermined number is greater than two and less than ten. Particularly preferred is the predetermined number three, four or five.

It can be said that a detected location information always applies as the first location information according to the invention if it is included in the decision as to whether a second transaction is to be permitted or not by determining its difference from the second location information.
Likewise, detected location information always applies as second location information according to the invention if it is included in the decision as to whether a second transaction is to be admitted or not by determining its difference from the first location information.

Preferably, the vehicle device according to the invention is designed to detect, as second location information, one of a plurality of location information acquired temporally following the acquisition of the first location information whose location information difference from the first location information is greater than the predetermined difference amount, if the location information difference of at least one of the plurality of acquired location information to the first location information is greater than the predetermined difference amount, and as second location information one of a plurality of detection of the temporally subsequent to first location information to detect detected location information when the location information difference from none of the plurality of acquired location information to the first location information is greater than the predetermined difference amount.
In particular, this embodiment relates to a vehicle device according to the invention comprising a position determination device, wherein the first and second location information are absolute location information in the form of first and second positions, and wherein the vehicle device is configured to receive the first position and the second position from the position determination device by means of
Determine position determining device.
In particular, it can be provided that by such a vehicle device stored in the vehicle device second location information whose location information difference to the first location information is greater than the predetermined difference, not by a subsequent to the stored second location information, detected location information whose location information difference to the first location information is not larger than the predetermined difference amount, is replaced.
Such a configuration of the vehicle device according to the invention advantageously ensures that a second transaction is enabled not only with a device other than the first roadside device but also with the first roadside device when the vehicle with the vehicle device moves after the vehicle once removed far enough from the first roadside facility.
For it may well be that a vehicle that carries the vehicle device according to the invention, after passing the first roadside device of a first section of a road leaves this road, without a first section of the section following second section of this road to drive on which a second roadside device is arranged, and ascends in the course of a turning maneuver in the opposite direction or after passing through a loop off the said road in the original direction again on the first stretch. In this case, upon re-passage of the vehicle device of the first roadside device, the location information difference of a second location information related to the first location information acquired in the vicinity of the first roadside device would not necessarily be greater than the predetermined difference amount unless it had been determined that the second location information would be one the one of a plurality of, after the detection of the first location information temporally subsequent, to acquire detected location information whose location information difference from the first location information is greater than the predetermined difference, when the location information difference of at least one of the plurality of detected location information to the first location information is greater than the predetermined difference amount ,

In particular, such a vehicle device according to the invention can be further developed to acquire as second location information that of the plurality of location information acquired subsequently from the first location information, which was last acquired temporally from the plurality of acquired location information, if the location information difference from none of the plurality of acquired location information to the first location information is greater than the predetermined difference. For example, it can be provided that a previously recorded location information stored as second location information in the vehicle device is overwritten by a location information subsequently acquired by such a vehicle device if neither the location information previously acquired nor the subsequently determined location information has a location information difference which is greater as the difference amount, and a second location information previously acquired as second location information stored in the vehicle device, the Location information difference to the first location information exceeds the difference, is not overwritten by subsequently detected location information whose location information difference to the first location information is not greater than the difference amount.
Alternatively, regardless of whether at least one or none of the plurality of location information acquired subsequent to the detection of the first location information has a location information difference from the first location information larger than the predetermined difference amount, the vehicle device may be further developed as second location information of the plurality of location information acquired subsequent to the first location information whose location information difference from the first location information of the plurality of acquired location information has the largest location information difference from the first location information. By way of example, provision may be made for such previously-recorded location information to be overwritten by a location information acquired subsequently as second location information in the vehicle device if the subsequently acquired location information relating to the first location information has a location information difference that is greater than the location information difference, the previously acquired location information to the first location information, and a previously acquired location information stored as second location information in the vehicle device is not overwritten by a subsequently detected location information when the subsequently detected location information to the first location information has a location information difference that is not greater than the location information difference that the previously acquired location information has relative to the first location information.
Thus, this type of such in-vehicle device is always advantageously the one of all location information acquired since the acquisition of the first location information as stored second location information whose location information difference to the first location information is the largest of all location information acquired since the first location information was acquired. Detected location information whose location information differences from the first location information are smaller than the last stored second location information can then not replace this last stored location information, such that upon reentry into the communication area of the first roadside facility after leaving it, a second, this time second, transaction intended.

In particular, the in-vehicle device according to the invention is arranged to allow the first device to perform the first transaction in an active mode of operation of the vehicle device in which the vehicle device is configured to allow at least one transaction as a result of performing the first transaction from the active mode of operation to a passive mode of operation Change vehicle equipment in which the vehicle device is configured to not allow transaction, as a result of a determination that the difference between the second location information and the first location information exceeds a predetermined threshold to switch back from the passive mode of operation to the active mode of operation and in to allow the latter to perform the second transaction and, in the passive mode of operation, failing to determine that the difference between the second location information and the first second location information exceeds a predetermined threshold remain and in this no execution of the second transaction to admit.
In particular, such a vehicle device is configured in the active mode of operation to allow at least one transaction by the vehicle device to perform a transaction by transmitting a vehicle-side communication signal, by receiving a road-side communication signal, or by processing a received road-side communication signal.

In particular, such a vehicle device is designed in the passive mode of operation to not allow the second transaction following the first transaction.
Specifically, such a vehicle device is configured in the passive mode of operation not to allow a transaction in which the vehicle device in the passive mode of operation transmits no vehicle-side communication signal, suppresses the reception of any possibly transmitted road-side communication signal, or does not perform transaction-generating processing of a roadside communication signal received by the vehicle device.

Identical or equal components of different figures are provided with the same reference numerals.

Fig. 1a 1 schematically shows a first embodiment of a self-locating type vehicle device 30, which is identical to the structure, but not the embodiment, in the first and third exemplary embodiments, comprising a vehicle device 10 with a vehicle-mounted processor 11 and a DSRC communication module 20 and a displacement sensor 16b (for example an odometer, a odometer, a odometer or an odometer) includes, which are coupled with the vehicle device 10 data technology. Datentechnical couplings between data coupled with each other components are in Fig. 1 illustrated by continuous connecting lines between the coupled components. They can be realized by interfaces, connecting lines or wireless communication means (eg bluetooth). The on-vehicle processor 11 is configured to send data to the DSRC communication module processor 21 of the DSRC communication module 20 by executing a computer program loaded in the working memory 17b from the data RAM 17a and to receive data from him. Accordingly, by executing a computer program stored in the DSRC communication module data RAM 27a, the DSRC communication module processor 21 is configured to receive and send data to and from the vehicle processor 11. A GNSS position determining device 12 receives signals from unillustrated satellites of a Global Navigation Satellite System (GNSS), such as GPS, through its GNSS receiving antenna 12b and determines its provisional position from the received satellite signals by means of its GNSS receiver 12a - and thus the provisional position of a vehicle 40 (see Fig. 2a, 2b . 3a, 3b ), from which the vehicle device 30 is carried. The determined provisional position is further advanced by the processor 11 based on heading change values provided by a gyroscope 16a of the on-vehicle device and relative path length values of a distance traveled in a particular time frame provided by the travel encoder 16b Position more precise final position (hereinafter referred to only as "position") processed in the course of a known as a coupling location method.
In an alternative embodiment variant, the signals of the gyroscope 16a and the displacement transducer 16b may be directed to the GNSS position determination device 12 instead of the processor 11, the GNSS position determination device 12 performing the coupling location and providing the coupled position to the vehicle-mounted processor 11.
The position determination by the processor 11 and / or the GNSS position determining device 12 is repeated - for example, every second - in particular in the course of the movement of the vehicle 40 by the vehicle device 30th
Alternatively or cumulatively, a position determination can be carried out by the processor 11 in a manner known per se on the basis of the spectrum of cell identifications received by the mobile radio antenna from the base stations of a mobile radio network by a mobile transceiver 13 encompassed by the vehicle device 10. Nevertheless, position determination by means of the GNSS position determination device 12 is preferred for reasons of position accuracy.

The on-vehicle processor 11 is coupled to a security module 18 formed as a stand alone data processing unit (eg, a so-called smart card) having at least one autonomous control module 18a and memory area 18b, the autonomous control module 18a being configured to request one Output of data from the memory area 18b and / or the modification or recording of data in the memory area 18b to perform only against authentication. The authentication procedure can be carried out by analyzing a digital signature by means of a public key stored by the signer in the memory area 18b of the security module 18.

Instead of the security module 18, a cryptographic data memory (not shown) may be provided, in which the processor 11 can store data encrypted only with appropriate authentication and can read out in a decrypting manner.
The vehicle device 10 has a battery 19a for the power supply, in particular a rechargeable battery (for example an accumulator), and a power connection 19, via which both the vehicle device 10 can be supplied with power from the vehicle electrical system alternatively to the battery 19a. If the battery 19a is designed as an accumulator, it can be recharged via the power connection 19. The DSRC communication module 20 is also supplied with power via the interface between the vehicle device 10 and the DSRC communication module 20.

A vehicle identifier of the vehicle 40 is stored in the memory area 18b of the security module 18 or cryptographic data memory in the form of the vehicle license plate, which is encompassed by at least one vehicle license plate of the vehicle 40. Alternatively or optionally, the vehicle identifier may be stored in the data RAM 17a.
Furthermore, an axle class and a pollutant class, the combination of which forms a vehicle class, are stored in the memory area 18b of the security module 18. Together with the vehicle identifier, this data forms a set of vehicle data.
An initial registration or change of the vehicle identification, the axle class and / or the emission class can be effected by the user by sending corresponding data and instructions to the processor 11 via a user interface, not shown (Bluetooth interface, USB interface, keyboard or touch-sensitive display device) the vehicle device transmitted.
It can also be effected by a central data processing device, not shown, located outside and away from the vehicle 40, to which the user has previously transmitted the data of the initial registration or modification, by the central data processing device a corresponding instruction for initial registration or modification of the vehicle identification, the axle class and / or the vehicle class via a mobile network to the vehicle device 30 which receives this instruction together with the new data by means of a mobile radio transceiver 13 via the mobile antenna 13b and processed by the vehicle-mounted processor 11. The encrypted storage of the vehicle identifier, the axle class and / or the pollutant class in the memory area 18b of the security module 18 or in the cryptographic data memory can be initiated by means of appropriate instructions by the vehicle-mounted processor 11.
After having stored this vehicle data in the security module 18, the vehicle processor 11 transmits it to the DSRC communication module 20, whose DSRC communication module processor 21 receives the vehicle data and stores it in a DSRC communication module main memory 27b. Alternatively or cumulatively, the vehicle data may also be stored in the DSRC communication module data RAM 27a.

The DSRC communication module 20 is spaced apart from the vehicle apparatus 10 on the inside of the windshield of the vehicle 40 so that the DSRC transceiver 23 by means of its DSRC transmitting and receiving means 23 b with a roadside first DSRC communication device located outside the vehicle 40 61a of a first roadside device 60a (see Fig. 2a and Fig. 3a ) or with a second roadside DSRC communication device 61b of a second roadside device 60b (see FIG Fig. 2b ) one can communicate. A DSRC communication carrier is microwave in the frequency range of 5.8 GHz. Alternatively or cumulatively, infrared radiation (eg 850 nm) is possible as the DSRC communication carrier. In particular, the DSRC transmitting and receiving means 23b may be formed in several parts and a transmitting means (transmitting antenna in the case of microwave DSRC communication, IR light emitting diode (IR LED) in the case of infrared DSRC communication) and a receiving means (receiving antenna in Cases of microwave DSRC communication, IR photodiode (IR-PD) in the case of infrared DSRC communication).

The processor 11 detects - as already mentioned - every second a position of the vehicle 40 and processes the detected position data of these positions for the purpose of collecting a vehicle-related toll, which is to be collected for the use of a section of the track by the vehicle 30, based on the detected position data is identifiable.
In the course of a decentralized toll calculation, the vehicle-mounted processor 11 compares thereto position data of one or more detected positions with geographical elements (so-called toll geo-objects) of a digital map to which a respective identifier of a route section is assigned by means of a toll collection program running in memory 17b. If there is sufficient geographical agreement of the acquired position data with a specific geographical element, the route section whose identifier is associated with the particular geographic element is recognized as being traveled. Subsequently, the vehicle-mounted processor 11 determines a toll charge based on the identifier of the section of road identified as traveled, which depends on the axle class and the pollutant class of the vehicle 30.
In this respect, axle class and pollutant class are toll-relevant data of the in-vehicle equipment, because they determine the amount of the toll charge and insofar influence the processing of the position data on a vehicle-related toll fee.
Subsequently, the central processor 11 instructs the mobile radio transceiver 13 to send the determined toll charge together with the vehicle identifier via a mobile radio network to a central data processing device (not shown) of a toll collection system. The central data processing device assigns the toll fee to a user account on the basis of the vehicle identifier, from which the toll fee is deducted by a data processing device of a bank (not shown) from the account of the toll operator.
Alternatively or cumulatively to the decentralized toll charge determination by the vehicle device 30, a central toll charge determination is possible, to which the vehicle device transmits the detected positions together with the vehicle data by means of the mobile radio transceiver 13 to a central data processing device (not shown) remote from the vehicle 40 same or similar as in the case of the decentralized toll calculation described the toll fee determined.

The vehicle device 30 is designed to carry out the steps of the method according to the invention by the vehicle device 10 and the DSRC communication module 20 interacting.

Fig. 1b schematically shows a used in the second embodiment, a third-kind vehicle device 30 in the form of a DSRC communication module 20, which can optionally be used instead of the first embodiment for carrying out the method according to the invention and a DSRC communication module processor 21 connected to a DSRC communication module data read-write memory 27a, DSRC communication module working memory 27b, DSRC communication module signaling means 25, a DSRC transceiver 23 having a DSRC transmitting and receiving means 23b, a DSRC communication module GNSS position determining means 22 having a DSRC communication module GNSS receiving antenna 22b and being coupled to a battery 29a for power supply.
The above-mentioned vehicle data are transmitted via a DSRC transceiver 23 to the DSRC communication module 20 via a DSRC communication equipment (not shown) and from the DSRC communication module processor 21 in the DSRC communication module data write-read memory 27a saved.
Alternatively, the vehicle data may be input via an input interface (keyboard, touch-sensitive display device), not shown, of the DSRC communication module 20.
The DSRC communication module data read / write memory 27a also stores a computer program product which comprises instructions for carrying out the method according to the invention and, when executed by the DSRC communication module processor 21, forms the DSRC communication module 20 according to the invention.

An in Fig. 1c shown alternative embodiment of the DRSC communication module 20 formed vehicle device 30 is used in the third embodiment and differs from the in Fig. 1 b shown DSRC communication module 20 in that it has no DSRC communication module GNSS position determining means 22; instead, the alternative embodiment receives the first position from the first DSRC roadside communication device 61a and the second position 61b - in the event of a second transaction - from the DSRC second roadside communication device 61b via the DSRC transceiver 23.

The vehicle devices 30 of the FIGS. 1a . 1b and 1c communicate in the first, second and third embodiments according to a first signal flow diagram of Fig. 9a with the roadside devices 60a and 60b. At this time, the roadside devices 60a and 60b send initialization signals in the form of request signals 91a / 91b every 10 milliseconds, one of which is received by the DSRC communication module 20 of the vehicle device 30 when the vehicle 40 on the road 50 enters the respective one Communication area 62a or 62b occurs.
If the vehicle device 30 is designed to allow the transaction to be carried out, it sends a response signal in the form of an information signal 94a / 94b, with which the roadside device 60a or 60b can request the required information (control information in the case of a control transaction, identification information in the event of a toll transaction). provides. If the roadside device 60a or 60b has received this information, it sends an acknowledgment signal 97a / 97b, the reception of which evaluates the vehicle device 30 as proof of the successful execution of the transaction.
Optionally, one or more further signals can be sent and received between the communication partners between the request signal 91a / 91b and the information signal 94a / 94b.
If, for example, the BST (beacon service table) is sent by the roadside device 60a and 60b in an initialization phase according to a DIN EN ISO 14906 CARDME transaction as the request signal 91a / 91b, it will initially be provided by the vehicle device with its VST in the initialization phase (vehicle service table) answered. In a subsequent presentation phase, the roadside device 60a or 60b then sends its concrete information request in a request signal 93a / 93b, which is answered by the vehicle device in the presentation phase by the transmission of the information signal 94a / 94b.

The vehicle device 30 of the FIG. 1a communicates in the fourth embodiment according to a second signal flow diagram of Fig. 9b with the roadside devices 60a or 60b. At this time, when the vehicle device 30 is configured to allow the transaction to be performed, the DSRC communication module 20 sends presence signals 92a / 92b every 10 milliseconds, one of which is then received by the roadside device 60a or 60b, if the Vehicle 40 on the road 50 enters the respective communication area 62a or 62b.
In this case, the roadside device 60a or 60b sends a response signal in the form of a request signal 93a / 93b requesting specific information from the vehicle device.
If the vehicle device 30 is designed to allow the transaction to be carried out, it in turn sends a response signal in the form of an information signal 94a / 94b, with which the roadside device 60a or 60b receives the requested information (control information in the case of a control transaction, identification information in the event of a toll transaction ). If the roadside device 60a or 60b has received this information, it sends an acknowledgment signal 97a / 97b, the reception of which evaluates the vehicle device 30 as proof of the successful execution of the transaction.

In the following, when the vehicle device 30 is generally referred to, both the first embodiment (vehicle device 10 coupled to a DSRC communication module 20) and the second embodiment (DSRC communication module 20) may be meant, if referring to the vehicle device 10 or one of its components does not necessarily indicate that only the first embodiment is meant.

For the first, second and third embodiments shows Fig. 2a a traffic flowing at a first traffic situation at a first time in which there is a first transaction by a communication between a vehicle-side DSRC communication module 20 of a vehicle device 30 according to the first or second embodiment of a vehicle 40 and a first DSRC-side communication device 61a at a first roadside means 60a in the form of a first bridge 60a spanning the road 50 transversely to the direction of travel in the area of a first DSRC communication zone 62a of the first DSRC-communication device 61a.

For the first, second and third embodiments shows Fig. 2b a, compared to the first time by a time interval .DELTA.t of, for example, 1 minute, in which the vehicle 40 has moved out of the first DSRC communication zone 62a of the first DSRC-side communication device 61a, time-delayed, second time of the first traffic situation flowing traffic in which it to a second transaction by a communication between the on-vehicle DSRC communication module 20 of the vehicle device 30 according to the first or second embodiment of the vehicle 40 and a second DSRC side communication device 61b on a second roadside device 60b in the form of a cross-directional road 50 second bridge 60b in the area of a second DSRC communication zone 62b of the second DSRC roadside communication device 61b, the second bridge 60b being spaced from the first bridge 60a in the direction of travel by a distance ΔL of 2 kilometers ,

The first roadside device 60a is in Fig. 2a, Fig. 2b . Fig. 3a and Fig. 3b arranged at / over a first stretch of road 50.
The second roadside device 60b is in Fig. 2a and Fig. 2b arranged on / over a second stretch of the road 50, which connects in the direction of travel of the vehicle 40 directly to the first route section, wherein the interface between the first stretch and the second stretch is formed as a node (not shown) on which the vehicle 40 the Road 50 can leave without driving on the second stretch. A node-forming exit from the road 50 is spaced one kilometer from the first roadside device 60a in the direction of travel. From here, the vehicle 40 can again drive onto the road 50 and drive the first route section in the opposite direction, whereby it again enters a communication area of the opposite lane (not shown) of the first roadside device 60a, or via a parallel path (not shown) off the road 50 come to a driveway in the direction of travel of the first link section to re-enter the first communication area 61a of the first roadside device 60a.

For the first, second and third embodiments shows Fig. 3a a second traffic situation of stagnant traffic at a first time, in which there is a first transaction by a communication between a vehicle-side DSRC communication module 20 of a vehicle device 30 according to the first or second embodiment and a first roadside DSRC communication device 61a at a first roadside device 60a in the form of a first bridge 60a spanning the road 50 transversely to the direction of travel in the region of a first DSRC communication zone 62a of the first DSRC communication device 61a on the road.

For the first, second and third embodiments shows Fig. 3b a, compared to the first time by a time interval .DELTA.t of, for example, 1 minute, in which the vehicle 40 has not moved out of the first DSRC communication zone 62a of the first DSRC-side communication device 61a, time-delayed, second time of the second traffic situation stagnant traffic, in there is no second transaction through communication between the on-vehicle DSRC communication module 20 of the vehicle device 30 according to the first or second embodiment of the vehicle 40 and the first DSRC roadside communication device 61a on the first roadside device 60a in the form of the road 50 across The direction-spanning second bridge 60b comes in the area of the first DSRC communication zone 62a of the first DSRC-communication device 61a.

In the first, second, third, and sixth embodiments, it is the DSRC roadside communication devices 61a and 61b that repetitively issue request signals every 10 milliseconds to communicate with a vehicle-side DSRC communication module 20 of a possibly approaching vehicle 40.

In the fourth embodiment, it is the vehicle-side communication module 20 of the vehicle 40 that repeats the presence signals 92a or 92b repeatedly every 10 milliseconds Fig. 9b to communicate with a DSRC roadside communication device 61a or 61b in whose DSRC communication zone 62a or 62b the vehicle 40 is entering on its journey.

While the FIG. 3a insofar as the traffic situation of the fourth exemplary embodiment is reproduced, the FIGS. 2a and 2b for adapting traffic flowing in a traffic situation corresponding to the fourth exemplary embodiment in such a way that Fig. 2a does not reflect broadcasting activity of the second DSRC roadside communication device 61b and Fig. 2b does not reflect broadcasting activity of the first DSRC roadside communication device 61a. The Fig. 3b would be adapted to represent a traffic situations stagnating traffic according to the fourth embodiment in such a way that Fig. 3b does not reflect broadcasting activity of the first stream side DSRC communication device 61a.

In the fifth embodiment, the vehicle-side DSRC communication module 20 of the vehicle 40 does not send an information signal to the roadside device 60a or 60b, with which it would provide the roadside device 60a or 60b with identification information for tolling or control information for control. Instead, the roadside device 60a or 60b transmits, as part of a roadside information signal 95a or 95b, its identification information, which the DSRC communication module 30 processes for tolling.
Such a transaction may be done without a response signal from the DSRC communication module 20 so that the communication between the on-road device 60a or 60b and the vehicle device 30 may remain unidirectional. In the Fig. 2a, Fig. 2b and Fig. 3a In this case, no transmission activity of the DSRC communication module 20 would be noted. If the DSRC communication module 20 optionally sends an acknowledgment signal 96a or 96 in response to the reception and processing of the information signal from the roadside device 60a or 60b to the roadside device 60a or 60b, then FIGS. 2a, 2b and 3a in this case, the situation of the transmission activity of the DSRC communication module 20 correctly.

FIRST EMBODIMENT

The inventive method, the vehicle device according to the invention and the system according to the invention according to the first embodiment will be described with reference to the in Fig. 4 illustrated method steps, the vehicle device 30 of Fig. 1a performs, in conjunction with the Fig. 2a, Fig. 2b . Fig. 3a, Fig. 3b and Fig. 9a explained.
In this embodiment, the DSRC communication module 20 serves, upon request by means of a request signal 91a / 91b (eg BST, beacon service table) from a roadside device 60a / 60b, to provide the roadside device with control information in an information signal 94a / 94b to transfer. As such, the roadside devices 60a and 60b are control devices. A control transaction performed in the communication between the roadside device 60a / 60b and the vehicle device 30 starts with the receipt of the request signal 91a / 91b of the roadside device 60a / 60b in the vehicle device 30 and includes receiving the control information of the vehicle device 30 in the vehicle roadside device 60a / 60b as part of the information signal 94a / 94b.
In order for the vehicle device 30 to register the successful execution of the control transaction, the roadside device 60a / 60b sends an acknowledgment signal 97a / 97b to the vehicle device 30 after having received the control information.

The control transaction ends with the receipt of the acknowledgment signal 97a / 97b of the roadside device 60a / 60b in the vehicle device 30.
The duration of the control transaction is typically 100 milliseconds. Control transactions with durations up to 90 milliseconds shorter or up to 100 milliseconds longer are also possible.

Based on a status description of the vehicle device 30 included in the control information, an unillustrated processor of the on-road device 60a / 60b can judge whether the vehicle device 30 is operable. Optionally, the processor of the road-side device 60a / 60b can judge whether the vehicle device functions as intended by means of an identifier of the route section last collected by the vehicle device 30, optionally contained in the requested control information. Optionally, the processor may judge the roadside device 60a / 60b by comparing a characteristic (eg, the axle count) of the vehicle 40 with the vehicle data of the vehicle 40, optionally included in the requested control information, by comparing the roadside device 60a / 60b whether vehicle data used by the vehicle facility 30 to calculate the toll amount is correct.

In step 401, the vehicle device 10 detects in an active operating mode of the vehicle device 30 in which the vehicle device 30 is designed to contribute to the execution of a control transaction by the DSRC communication device 20 as a result of the receipt of a request signal 91 a / 91 b by means of its vehicle device. Processor 11 from a calculated and provided by the GNSS position determining means 12 first provisional position on the basis of data from the encoder 16b and the gyroscope 16a by a known coupling location a first position and stores them in the main memory 17b. Alternatively, the on-vehicle processor 11 detects the first provisional position calculated and provided by the GNSS position determiner 12 as the first position. Subsequently, the vehicle-mounted processor 11 checks in step 402 whether a first request signal 91a has been received from the DSRC communication module 20 from a first DSRC-side communication device 61a. The information that a first request signal 91a has been received is given to the vehicle-mounted processor 11 by the DSRC communication module processor 21, which processes received request signals 91a / 91b. As long as the vehicle-mounted processor 11 receives no information about the receipt of a first request signal 91a from the DSRC communication module 20, it continuously records a first position every second with which it overwrites the first position in the main memory 17b received immediately before.

When the DSRC communication module 20 receives a first request signal 91a from the first DSRC roadside communication device 61a, since the vehicle device 30 is in the active mode of operation, the first request signal is answered with a first response signal, for example the VST (vehicle service table ). With the transmission of the response signal, the vehicle device 30 contributes to the first control transaction according to step 403. In the context of a first information signal 94a, which may be a first response signal, a second or further response signal, the DSRC communication module 20 transmits the control information (s) requested by the first roadside device 60a by the DSRC communication module processor 21 requested control information (s) from the DSRC communication module data RAM 27a and / or DSRC communication module RAM 27b and transmits to the DSRC transceiver 23 for transmission (see Fig. 2a . Fig. 3a ). As a result of receiving a first acknowledgment signal 97a from the first DSRC roadside communication device 60a, the DSRC communications module processor 21 registers the successful completion of the first control transaction in step 404 and communicates this registration to the vehicle processor 11 in the form of a registration message as evidence of this; in that the vehicle device 30 received a first request signal 91 a. Thereupon, the vehicle-mounted processor 11 detects further positions, but no further first position. The last received before receiving the registration information first position thus remains at least temporarily stored in the main memory 17b of the vehicle unit and will not initially overwritten with another received position.
Depending on whether or not the first time of detection of the last detected first position falls within the period of the control transaction, the first time lies after or before the reception time of the first request signal 91a.
Thus, the vehicle device 10 is configured to detect at least one position at a plurality of detection times, and to use a detected position as the first position of the plurality of detected positions, the first detection time of a first communication time of the transmission or the reception of a first communication signal - in this case the request signal 91a - immediately precedes or follows the first control transaction.
As a result of the registration of the execution of the first control transaction, the vehicle device 30, controlled by the Fährzeuggerät processor 11 automatically in a passive mode of operation in which the vehicle device 30 is configured to allow no second control transaction following the first control transaction (step 405). In this passive mode of operation, the DSRC communication module 22 does not answer a single prompts signal sent by a DSRC roadside communication device, particularly the first DSRC roadside communication device 61a, thus leaving out another control transaction in the passive mode of operation. In other words, the vehicle device 30 ignores any received request signals or does not even receive them.
This leads to it according to Fig. 3b no renewed communication between the DSRC communication device 20 and the first DSRC roadside communication device 61a, and thus no repetition of the first control transaction.

In the data read / write memory 17a of the vehicle device, in addition to the toll geo-objects, control geo-objects each characterized by at least one geographic position are stored, which spatially correlate with and correspond to the locations of the roadside devices 60a, 60b each associated with a limit distance. The limit distance for each first roadside device 60a is each set to be smaller than the largest distance that the vehicle is to enter on the shortest path from the first roadside device 60a to the same first roadside device 60a or the nearest second roadside device 60b in the communication zone 62b to the first roadside device 60a.
As a result of the registration of the registration of the execution of the first control transaction, the vehicle-device processor determines the first control geo-object that spatially correlates with the last detected first position. For example, it compares the first position with the geographical position of one or more control geo-objects and determining that control geo-object as correlating whose geographical position is no more than a predetermined radius of the control geo-object, spaced from the first position, the radii of the control geo-objects are each small enough that the control geo objects do not overlap.
The limit distance to the first control device 60a, which is stored for the determined correlating control Geo objects, is 0.6 kilometers smaller than the distance of the first control device 60a to the second control device 60b, which is ΔL = 2 km. The vehicular processor 11 stores the limit distance for the first position, which is 0.6 km, in the work memory 17a for the subsequent comparison process.
In an alternative embodiment, the vehicle device 30 will operate without these control geo-objects and will only have a general fixed limit value of 0.6 km stored in the data-write-read memory 17a.

In the passive mode of operation, in step 406, the vehicle processor 11 detects a second position immediately after the last detected first position. In step 407, the vehicle-mounted processor 11 compares this second position with the first position stored in the main memory 17b to determine whether the positional difference between the second position and the first position is greater than the predetermined limit distance of 0.6 kilometers. As long as this is not the case, the processor repeats steps 406 of detecting a second position and 407 of the comparison. If the distance of the first position and a second position detected at a second time point following the first time point finally exceeds the limit value of 0.6 kilometers, then the vehicle device 30, controlled by the vehicle device processor 11, automatically switches back to step 408 the active mode of operation in which the vehicle device 30 is arranged to contribute to the execution of a control transaction as a result of the receipt of a request signal by the DSRC communication device 20.
In this respect, the vehicle device 10 is designed to detect, as a second position, one of a plurality of positions detected chronologically following the detection of the first position whose positional difference from the first position is greater than the predetermined limit distance if the position difference of at least one of the several detected positions to the first position is greater than the predetermined limit distance, and to detect, as the second position, one of a plurality of positions detected subsequent to the detection of the first position, when the position difference from none of the plurality of detected positions to the first position is greater than the predetermined one limit distance.
A position detected following the change to the active operating mode is then a new first position in the sense of step 401, which replaces the last detected first position in the main memory 17b as the first position.
Once again put into the active mode of operation, the vehicle device 30 carries out a second control transaction in the sense of receiving a second request signal 91b from the second roadside device 60b, which spans the road 50 in the direction of travel 2 kilometers after the first roadside device 60a Fig. 2b by allowing the onboard DSRC communication module 20 to communicate with the second DSRC roadside communication device 60b.
The limit distance of 0.6 km is also smaller than the distance between the first roadside device 60a and the mentioned exit from the road 50 at 1 kilometer distance from the first roadside device 60a. This descent represents the farthest point on an immediate detour loop from a first passage of the first roadside device 60a to a second passageway of the first roadside device 60a. With the definition of a limit distance less than this one kilometer distance becomes allows the vehicle device to switch back to the active mode of operation before reaching the farthest point, so that a second transaction with the first roadside device 60a is allowed as intended. If the predetermined limit distance were greater than this distance, the vehicle device would not switch back to the active operating mode on this loop travel, which would preclude an intended second transaction with the first roadside device 60a.

For the technical implementation of an active operating mode and a passive operating mode and a change between these two operating modes in the vehicle device 30, there are numerous possibilities.

In a first implementation example, the DSRC communication module main memory 27a stores a status bit (flag) with the value 0 or 1, which the DSRC communication module processor 21 consults when it receives a request signal from the DSRC transceiver 23. In the active mode of operation, the flag is set to 0 so that the DSRC communication module processor 21 responds to the request signal to arrive at a first transaction. In passive mode, the flag is set to 1 so that the DSRC communication module processor 21 does not respond to the request signal to avoid performing a second transaction. To change from the active mode of operation to the passive mode of operation, the vehicle processor 11 instructs the DSRC communication module processor 21 to set the status bit to 1. To change from the passive mode of operation to the active mode of operation, the vehicle processor 11 instructs the DSRC communication module processor 21 to set the status bit to 0. Alternatively, the DSRC communication module processor 21 may automatically make the change from the active operation mode to the passive operation mode on the basis of the receipt of the acknowledgment signal 97a.

In a second implementation example, in the active mode of operation, the DSRC transceiver 23b is provided with electrical operating power so that it can provide data of received prompts to the DSRC communication module processor 21 and send response signals. In the passive mode of operation, the DSRC transceiver 23b is not supplied with electrical operating power so that it can not render received signals to data that it could provide to the DSRC communication module processor 21. Nor can it send response signals without electrical operating current. For example, the transmission means of an IR LED of an IR-DSRC communication module 20 can generate no light signal without operating current.
To change from the active mode of operation to the passive mode of operation, the on-board processor 11 instructs the DSRC communication module processor 21 to prohibit the power supply to the DSRC transceiver 23b. To change from the passive mode of operation to the active mode of operation, the on-board processor 11 instructs the DSRC communication module processor 21 to establish the operating power supply to the DSRC transceiver 23b. Alternatively, the DSRC communication module processor 21 can automatically make the change from the active operating mode to the passive operating mode on the basis of the receipt of the acknowledgment signal. The operating power supply can be interrupted and restored by the electrically controlled operation of a switch in the operating power supply of the DSRC transmitting and receiving means 23b.

In a third implementation example, in the active mode of operation, the DSRC transmitting and receiving means 23b is not shorted so that it can receive request signals and send response signals. In the passive mode of operation, the DSRC transceiver 23b is shorted so that there are no prompts can receive and / or can not send response signals. For example, the receiving means of an IR photodiode of an IR-DSRC communication module 20 can provide no receive signal in the event of a short circuit of the IR photodiode. Neither can a shorted transmit antenna of a microwave DSRC communication module 20 send a response signal.
To change from the active mode of operation to the passive mode of operation, the vehicle processor 11 instructs the DSRC communication module processor 21 to short-circuit the DSRC transmitter or the DSRC receiver of the DSRC transmitter and receiver 23b. To change from the passive mode of operation to the active mode of operation, the vehicle processor 11 instructs the DSRC communication module processor 21 to cancel the short circuit of the DSRC transmitter or the DSRC receiver of the DSRC transmitter and receiver 23b. Alternatively, the DSRC communication module processor 21 can automatically make the change from the active operating mode to the passive operating mode on the basis of the receipt of the acknowledgment signal.
The short circuit can be established and canceled by the electrically controlled actuation of a switch on the connections of the DSRC transmitter or the DSRC receiver.

Further alternative implementation examples would bring the skilled person from his expertise for use in the vehicle device 30 according to the invention as needed.

SECOND EMBODIMENT

The inventive method, the vehicle device according to the invention and the system according to the invention according to the second embodiment will be described with reference to the in Fig. 5 illustrated method steps, the vehicle device 30 in the form of a DSRC communication module 20 of Fig. 1b performs, in conjunction with the Fig. 2a, Fig. 2b . Fig. 3a, Fig. 3b and Fig. 9a explained.

In this exemplary embodiment, the DSRC communication module 20 is used, on request by means of a request signal 91a / 91b (eg BST, beacon service table) from a roadside device 60a / 60b, to provide the roadside device with data in its DSRC communication module data. Read-write memory 27 a stored identification information in the form of an identifier of the DSRC communication module 20 and / or a license plate of the vehicle 40 in the context of an information signal 94a / 94b for the purpose of assigning a toll fee to transmit that for driving on the respective stretch of road is raised, on which the vehicle 40 passes the respective roadside device 60a / 60b associated with the respective route section. The respective roadside device 60a / 60b forwards the received identification information, together with its own identifier of the roadside device 60a or 60b - for example an identifier of the route section to which it is arranged - to an unillustrated central facility which charges the toll Depending on the toll-related vehicle data (number of axles, pollutant class, permissible total weight, etc.) calculated depending on the road section and optionally in addition to the identification information from the DSRC communication module 20 as part of the information signal 94a / 94b to the respective roadside device 60a or 60b has been assigned to a natural or legal person or at least to a means of payment (credit card, bank account) linked to the identification information.

As such, the roadside devices 60a and 60b are survey devices that perform a toll collection transaction in communication with the DSRC communication module 20. A toll transaction performed in the communication between the roadside device 60a or 60b and the DSRC communication module 20 starts with the reception of the request signal 91a / 91b of the roadside device 60a / 60b in the DSRC communication module 20 and includes receiving an information signal with the identification information of the DSRC communication module 20 in the roadside device 60a / 60b.
In order for the DSRC communication module 20 to register the successful completion of the toll transaction, the roadside device 60a / 60b sends an acknowledgment signal 97a / 97b to the DSRC communication module 20 after receiving the identification information.
The toll transaction ends with the receipt of the acknowledgment signal 97a / 97b of the roadside device 60a / 60b in the DSRC communication module 20.
The duration of the toll transaction is typically 100 milliseconds. Toll transactions with up to 90 milliseconds shorter or up to 100 milliseconds longer durations are also possible.

In step 501, the DSRC communication module acquires, via its DSRC communication module processor 21, a first position calculated and provided by the DSRC communication module GNSS position determiner 22 and stores it in a first memory address DSRC communication module memory 27b. Subsequently, the DSRC communication module processor 21 checks in step 502 whether a first request signal 91a has been received from the DSRC transceiver 23 from a first roadside communication device 61a. As long as the DSRC communication module processor 21 receives no information about the receipt of a first request signal 91a from the DSRC transceiver 23, it continuously acquires a first position every second with which it reads the first position received immediately before in the DSRC communication module. Overwrites memory 27b at the first memory address.

When the DSRC transceiver 23 receives, by means of its DSRC transmitting and receiving means 23b, a first request signal 91a, for example a beacon service table, from the first DSRC roadside communication device 61a on a first link, the DSRC communication module 20 responds Prompt signal, controlled by its DSRC communication module processor 21, with a first response signal, such as the VST (vehicle service table), that it sends by means of the DSRC transceiver 23. With the transmission of the response signal, the DSRC communication module 20 contributes to the first toll transaction according to a first sub-step of step 503. As part of an information signal 94a, which may be the first response signal or a second or further response signal, the DSRC communication module 20 transmits the identification information requested by the first roadside device 60a by the DSRC communication module processor 21 extracting the requested identification information from the DSRC. Communication module data read-write memory 27a reads and transmits the DSRC transceiver 23 for transmission (see Fig. 2a . Fig. 3a ). Upon receipt of the information signal, the first roadside device sends a first acknowledgment signal 97a about the successful completion of the first transaction, which also includes the limit distance (0.6 kilometers) to be used with respect to this first transaction.

As a result of receiving a first acknowledgment signal 97a from the first DSRC roadside communications device 60a, the DSRC communications module processor 21 registers the successful completion of the first toll transaction in a second sub-step at step 503 and, in response, copies the last detected first position at the first memory address is stored in the DSRC communication module main memory 27b to a second memory address in the DSRC communication module main memory 27b. Subsequently, the DSRC communication module processor 21 acquires a second position from the DSRC communication module position determiner 22, which stores it in place of the last stored first position below the first memory address in the DSRC communication module memory 27a (step 505). Depending on whether the first time of detection of the last detected first position falls within the period of the toll transaction or not, the first time is after or before the reception time of the first request signal 91 a. Thus, the DSRC communication module 20 is configured to detect at least one position at a plurality of detection times, and to use a detected position as the first position of the plurality of detected positions, the first detection time of a first communication time of the transmission or the reception of a first communication signal - In this case, the request signal 91a - immediately precedes or follows the first toll transaction.
The DSRC communication module processor 21 is designed to repeatedly detect second positions and store them respectively in place of the respectively previously detected second position below the first memory address until the position difference between the last stored second position and the stored first position is greater than one predetermined limit distance is (step 507, which will be discussed in more detail below) or the DSRC communication module 20 in step 505 receives a second request signal from the first or the second roadside DSRC communication device 61a or 61b.
In principle, a position subsequently detected for the purpose of rewriting the first position to the second memory address then becomes a - possibly transient - second position if it is stored below the first memory address. It is then used according to the invention as a second position when it is included in the decision as to whether a second transaction is to be admitted or not by differentiating with the first position.
Since the second position and the first position are both stored in the DSRC communication module main memory 27b, it is possible for the DSRC communication module processor to access these positions in a very small amount of time and their distance as the difference of their positions from each other in step 506 and a second request signal 91b is received by the DSRC communication module 20 in step 505.
Thus, the DSRC communication module 20 is configured to detect at least one position at a plurality of detection timings following a first detection timing of detection of the first position, and to use one detected position as a second position among the plurality of positions detected after the first detection time. whose detection time a second communication time of receipt of a second communication signal - in this case the second request signal 91b - immediately ahead of time by the vehicle device or whose position difference to the first position exceeds the predetermined limit distance. If the distance between the first position stored under the second memory address and the second position stored below the first memory address is greater than a predetermined limit distance of 0.6 kilometers, the vehicle 40 is located in the area of the second DSRC communication zone 62b of the second roadside device 60b which is located 2 km in the direction of travel on the road from the first roadside device 60a on a second track immediately following the first route section ( Fig. 2b ), and the DSRC communication module 20 is controlled by the DSRC communication module processor 21, contributing to the second toll transaction, which is requested by the second roadside device 60b with the second request signal 91b, by the DSRC communication module processor 21 sending to the DSRC transceiver 23 the identification data for sending as part of a second information signal 94b to the second roadside DSRC Communication device 61 b of the second roadside device 60b transmits (first sub-step of step 508). As a result of receiving a second acknowledgment signal 97b from the second roadside device 60b, the DSRC communication module 20 registers the execution of the second toll transaction (second substep of step 508).
If the distance between the first and the second position is smaller than the predetermined distance of 0.6 kilometers, the vehicle 40 is still located, for example, in the area of the first DSRC communication zone 62a of the first roadside device 60a with which it should not carry out a second toll transaction ( Fig. 3b ). In this case, the DSRC communication module processor 21 denies control of the DSRC transceiver 23. Thus, the DSRC communication module 20 does not send a response signal to the first roadside device 60a, thus avoiding a second toll transaction for the same link segment. In this case, the DSRC communication module 20 continues to acquire second positions.

In order to avoid the case of refusing to contribute to carrying out an authorized second toll transaction with the first roadside device 60a, which is required when the vehicle re-runs the first route section after leaving the first route section during a looping operation (eg Leaving the road 60 at the node between the first and second links 1 km after the first roadside detection means) without having passed through a second roadside device 60b is provided, even if no reception of the second request signal 91b occurs in step 505, at step 507 to have an additional process performed by the DSRC communication module processor 21, in which, analogously to step 506, the distance between the first and second positions is compared to the threshold distance. If it is the case that the distance is larger than the limit distance of 0.6 km, a fall action is taken for which there are several alternatives that are not detailed in the flowchart of FIG Fig. 5 are reproduced. To increase the reliability of this case, this measure can be done depending on the presence of a certain number of second positions whose distance to the first position is greater than the predetermined limit distance. For example, the fall measure can only take place when four out of five second consecutively provided second positions fulfill the criterion of exceeding the limit distance.
In all alternatives, the DSRC communication module 20 is configured to detect, as a second position, one of a plurality of positions detected subsequent to the detection of the first position whose positional difference from the first position is greater than the predetermined limit distance if the position difference of at least one of the plurality of detected positions to the first position is greater than the predetermined limit distance, and to detect, as a second position, one of a plurality of positions detected subsequent to the detection of the first position when the position difference from none of the plurality of detected positions to the first position is larger is the given limit distance.
In a first alternative, it may be provided to replace the stored first position at the second memory address with a predetermined first position whose distance to each second position achievable with the vehicle 40 is greater than the predetermined limit distance. Candidates for such predetermined first positions are a position in the middle of a larger lake (eg Müritz), in inaccessible high mountains (eg Zugspitze) or the position (0.90) at the North Pole. As a result, regardless of whether the vehicle 40 later approaches the first roadside device 60a again, after it has moved far enough away from its first DSRC communication zone 62a, it is ensured that this new first position represents the circumstance that the a new toll transaction with the first roadside device 60a is allowed. As a result, the DSRC communication module continues to detect positions provided by the DSRC communication module GNSS position determiner 22 as second positions that it deposits with the first memory address with each acquisition.
In a second alternative, the first position at the second memory address is once replaced by the last detected second position, which is then considered a new first position, and the predetermined limit distance is reduced to a new predetermined limit distance of 0.0 km. Thereafter, positions provided by the DSRC communication module GNSS position determining means 22 are stored as second positions without further comparison with the new first position stored at the second memory address at the first memory address until the DSRC communication module 20 receives a second prompt signal 97b. Only when the DSRC communication module 20 has received a second request signal 97b does the DSRC communication module processor 21 again carry out a position difference determination from the second position last stored under the first memory address and the position last stored under the second memory address as the first position and the latter Comparison with the new predetermined limit distance by. This always has to lead to the conclusion that a second transaction is permissible because of the specification of the new predetermined limit distance of zero.
In a third alternative, upon registration of the first transaction in step 503, a flag at a memory address is set equal to 1, causing the DSRC communication module processor 21 to compare second positions provided by the DSRC communication module GNSS position determiner 22 to the comparison of Submit step 506 or step 507. If the DSRC communication module 20 determines, before it has received a second request signal, in step 507 that the difference between the last detected second position and the stored first position is greater than the limit difference of 0.6 km, the flag becomes equal 0, causing the DSRC communication module processor 21 to not subject a second position stored by the DSRC communication module GNSS position determiner 22 to a comparison with the first position stored under the second memory address and receiving a second request signal 91b in step 510 automatically to transmit a second response signal, for example in the form of a second information signal 94b, whereby the DSRC communication module 20 contributes to the performance of a second transaction.
As a result, a contribution to the execution of a second transaction by the DSRC communication module 20 is denied if the flag is set equal to 1 and a contribution to the execution of a second transaction by the DSRC communication module 20 is permitted if the flag is set to 0 ,
In a fourth, preferred alternative, the DSRC communication module processor 21 overwrites the second position stored at the first memory address with a second position detected subsequent to the already stored second position only if the detected position is the first Position has a greater difference than the stored second position.
Thus, as the second location information that one of the plurality of location information acquired subsequently to the first location information is detected, whose location information difference from the first location information of the plurality of acquired location information has the largest location information difference from the first location information. This will be the case a loop ride avoided that after reaching a distance beyond the limit distance from the first roadside device on approaching the first communication zone 62a of the first roadside device 60a a detected position stored as a second position, or is used to decide whether the second Transaction is allowed or not, the difference to the first position is less than the predetermined limit distance.

In a further development of this exemplary embodiment, the DSRC communication module 20 is designed to refuse a contribution to a second toll transaction during a predetermined period of, for example, 30 seconds after registration of the first toll transaction, basically and independently of received second positions, because the vehicle is in the period of 30 Seconds after the registration of the first toll transaction impossible to comply with a valid in the first and / or second link speed limit can enter the second DSRC communication zone 62b. A speed limit non-compliant vehicle 40 would thus become the vehicle of a toll cardeller.
In the same way, the vehicle devices 30 of the other embodiments can also be developed.

THIRD EMBODIMENT

In the Fig. 1c illustrated embodiment of the third embodiment differs from the in Fig. 1b illustrated embodiment of the second embodiment in that the DSRC communication module 20 of the third embodiment does not DSRC communication module GNSS position determining means 22 includes. In this respect, the third embodiment differs from the second embodiment substantially in that the DSRC communication module 20 of Fig. 1c the required position information is received by the DSRC roadside communication device 61a and / or 61b as part of a message (eg BST) contained in the request signal.
During the journey through the first DSRC communication zone 62a of the first roadside device 60a (FIG. Fig. 2a .
Fig. 3a ) located at a first link, the DSRC communication module 20 receives from the first DSRC roadside communication device 61a according to step 601 of FIG Fig. 6 a first request signal 91 a, which includes a first position, in the form of the geographical coordinates of the first roadside device 60 a. This first position is stored by the DSRC communication module processor 21 in the DSRC communication module main memory 27b.
The DSRC communication module 20 contributes to the first toll transaction by sending its identification information to the first roadside device 60a with the first information signal 94a (step 602) and registers the first roadside DSRC communication device 61a by receiving a first acknowledgment signal 97a Carrying out the first toll transaction according to step 603.
Subsequently, the DSRC communication module 20 receives a second request signal 91b having a second position whose distance to the first position checks the DSRC communication module 20 in step 605. The second request signal 91b may be another request signal 91b of the first roadside device 60a according to FIG
Fig. 3b be. In this case, the second position corresponds to the first position, and the position difference is equal to zero, which is below the limit difference of 250 meters generally defined in this embodiment. Such Another request signal 91 b of the first roadside device 60 a is not answered by the DSRC communication module processor 21. Instead, the DSRC communication module 20 awaits the receipt of another request signal.
Derives the second request signal 91 b of the second roadside device 60b according to Fig. 2b which is disposed on a second road section 50 immediately following the first railway section, the position difference between the second position of the second roadside device 60b and the first position of the first two-kilometer roadside device 60a is greater than the 250-meter boundary difference, and the DSRC communication module processor 21 instructs the DSRC transceiver 23 to send the identification information with a second information signal 94b to the second roadside device 60b, whereby the DSRC communication module 20 makes its contribution to the second toll transaction in step 606. Finally, the DSRC communication module 20 registers the execution of the second toll transaction as a result of receiving the second acknowledgment signal 97b from the second roadside device 60b in step 607.
The second prompts signal 91b of the first roadside device 60a, after the vehicle 40 leaves the road 50 after the first link section at which the first roadside device is located, originates at a node to the second link section 1 km after the first roadside device 60a without driving on the second link and entering the second communication zone 62b of the second roadside device 60b, to avoid denying the contribution of the DSRC communication module to perform a legitimate second toll transaction with the first roadside device 60a, it is proposed to do so at the node another roadside device, not shown, from which the DSRC communication module receives a further first position, which replaced in a further transaction, the stored first position of the first roadside device and as a new first Po this position applies. This then has a distance of 1 km from the position of the first roadside device, which is greater than the limit difference of 250 meters, so that with the further position as the first position, a second transaction becomes possible as a result of a re-communication with the first roadside device whose now second position relative to the first position of the further roadside device has a distance of 1 km sufficient to carry out the second transaction.

FOURTH EMBODIMENT

The fourth embodiment differs from the first embodiment essentially by two features: First, the vehicle device 30 is waiting from Fig. 1a not passively respond to the input of a request signal from a roadside device 60a or 60b, but itself actively sends presence signals in 10 millisecond clock. On the other hand, the vehicle device serves as location information not absolute location information in the form of the position of the GNSS position determination device (which is still used to detect the toll payment), but a relative location information in the form of an odometer reading, which is transmitted from the encoder 16b or signals from the Positioner 16 b is determined by the vehicle-mounted processor 11.
With reference to Fig. 7 and Fig. 9b The DSRC communication module 20 sends out a first presence signal 92a according to step 701. If not answered in step 702, it will again send out a first presence signal 92a. The DSRC communication module 20 receives a first response signal in the form of a first request signal 93a from a first roadside device 60a according to FIG Fig. 2a Thus, it sends the required control information as part of a first information signal 94a, subsequently registers the successful completion of the first control transaction (step 703) following the receipt of a first acknowledgment signal 97a from the first roadside device 60a, and stops following the transmission of first presence signals 91a one. Via the event of the successful completion of the first control transaction, the DSRC communication module processor 21 of the DSRC communication module 20 sends a message to the vehicle device processor 11 of the vehicle device 10.
In response to the receipt of this transaction message, the vehicle processor 11 detects at a first time a first odometer reading that it stores in memory 17b (step 704). Subsequently, the vehicle-operating-device processor detects a second odometer reading at a second time in step 705 and compares this second odometer reading with the first odometer reading by subtraction. If the meter reading difference is less than a 0.6-kilometer limit difference (step 706), the vehicle-on-vehicle processor will detect a new second odometer reading at a later time.
The combination of steps 705 and 706 is repeated in the second cycle until the vehicle-mounted processor 11 determines that the meter reading difference has exceeded the limit difference of 0.6 kilometers. If so, the vehicle processor 11 sends an activation message to the DSRC communication module processor 21 requesting the DSRC communication module 20 to resume the transmission of prompt signals.
Without such an activation signal, the DSRC communication module 20 does not send any request signals, so that no second control transaction can occur in the area of the first DSRC communication zone 62a of the first roadside device 60a.
In response to the second request signal 92b sent in step 707, if the DSRC communication module 20 receives a second request signal 93b from the second roadside device 60b at step 708, it contributes to the transaction by registering the second information signal 94b with the requested control information subsequently, upon receipt of a second acknowledgment signal 97b from the second roadside device 60b, successful completion of the second control transaction at step 709.
Otherwise, it repeats the block of steps 707 and 708 every second until a second response signal in the form of a second request signal 93b from the second roadside device 60b is received.

FIFTH EMBODIMENT

First, the DSRC communication module 20 does not necessarily respond to an initialization signal in the form of an information signal 95a or 95b sent from the roadside devices 60a and 60b to the DSRC communication module 20, respectively according to Fig. 9c is sent; insofar as the communication between the roadside devices 60a and 60b and the DSRC communication module 20 can remain unidirectional. On the other hand, in the context of the initialization signal embodied as an information signal 95a or 95b, the roadside devices 60a and 60b each transmit an associated link identification which is processed by the DSRC communication module 20 at a toll charge which the DSRC communication module 20 receives from a (not in Fig. 1b shown) debits and / or by means of one of the DSRC communication module 20 included (not in Fig. 1b shown) mobile communication device sent to an unillustrated center of a toll system.
Thus, unlike the second embodiment, the toll transactions are not performed by the roadside devices 60a and 60b but by the DSRC communication module 20 after being prompted by the roadside devices 60a and 60b with the initialization signals (information signals) 95a and 95b ,
As such, it consists in steps 503 and 509 according to Fig. 5 In contrast to the DSRC communication module 20 of the second embodiment, the contribution to be made by the DSRC communication module 20 is not to send a response signal with vehicle identification information to the roadside devices 60a and 60b but from the roadside devices 60a and 60b to send sent identification information about the respective route section.
Such processing refuses the DSRC communication module 20 accordingly in step 508 in this fifth embodiment.
Optionally, the DSRC communication module 20 sends an acknowledgment signal 96a or 96b to the roadside device 60a or 60b according to FIG Fig. 9c if it has completed the toll transaction. The transmission of such an acknowledgment signal 96a or 96b is omitted in the case of refusing to carry out the toll transaction.

SIXTH EMBODIMENT

The method according to the invention, the road-side device according to the invention and the system according to the invention according to the sixth exemplary embodiment are described with reference to FIGS Fig. 8 illustrated method steps, the vehicle device 30 of Fig. 1b , the first roadside device 60a and the second roadside device 60b perform in conjunction with the Fig. 2a, Fig. 2b . Fig. 3a, Fig. 3b and Fig. 9a explained.
The sixth embodiment differs from the second embodiment in that the roadside device 60a or 60b decides on the execution of the toll transaction and not the DSRC communication module 20. For this, each roadside device 60a and 60b has first location information corresponding to the geographic coordinates of their corresponding location. The second location information determines the DSRC communication module 20 by means of its DSRC communication module GNSS position determination device 22. The data exchange between the DSRC communication module 20 and the roadside device 60a or 60b takes place according to the signal flow diagram of FIG Fig. 9a ,
In the flowchart of Fig. 8 For example, the steps performed by the first roadside device 60a and, if applicable, the second roadside device 60b are shown in boxes with dashed frame lines, while those steps performed by the DSRC communication module 20 are displayed in boxes with solid frame lines.
At a first roadside device 60a, the DSRC communication module 20 receives a first request signal 91a from the first roadside device 60a, which responds to the transmission of its identification information in the first information signal 94a. The first roadside device 60a carries out a first toll transaction with the identification information according to step 801 of FIG Fig. 8 through and send a first Acknowledge signal 97a to the DSRC communication module 20, the receipt of which causes the DSRC communication module 20 to detect a position provided by its DSRC communication module GNSS position determiner 22 as the first position and in the DSRC communication module data RAM 27a (step 802). Alternatively, the first roadside device 60a transmits its location position as the first acknowledgment signal 97a, and the DSRC communication module 20 stores the received location position as the first position in the DSRC communication module data RAM 27a.
Henceforth, the DSRC communication module 20 detects positions provided by the DSRC communication module GNSS position determining device 22 as second positions (step 803), and if no second request signal is received, after each detection of a second position by the DSRC communication module processor 21 a comparison of the detected second position with the stored first position is performed to determine if the position difference between the detected second position and the detected first position is greater than a limit difference of 0.6 km (step 805). If the position difference is smaller, a new second position is detected. Otherwise, the last sensed second position is stored in the DSRC communication module data RAM 27a without being overwritten by other locations provided by the DSRC communication module GNSS location determiner 22.
When the DSRC communication module 20 receives a second request signal 91b (step 804) from the first roadside device 60a or second roadside device 60b, it responds by sending a second information signal 94b which, in addition to the possible toll transaction identification information, stores the stored one second position (step 806). The roadside device 60a or 60b now compares the second position received from the DSRC communication module 20 with a first position that is in its own location position.
If it is the first roadside device 60a that receives this second position without the DSRC communication module 20 having left the first communication region 62a of the first roadside device 60a after the first transaction, the second position is no more than several tens of meters from the first position, and no second transaction is performed by the first roadside device 60a (step 808) and no second acknowledgment signal 97b is sent to the DSRC communication module 20. In this case, the DSRC communication module 20 proceeds to step 805.
It is the first roadside device 60a that receives this second position after the DSRC communication module 20 has not only left the first communication area 62a of the first roadside device 60a after the first transaction, but also the road 50 at a departure 1 km behind the first roadside device, to subsequently rejoin the first road section with the first roadside device 60a during the course of the journey of the vehicle 40, the second position differs by more than 0.6 km from the first position, and the first roadside device 60a performs a second toll transaction for the repeated use of the first link. To compensate for the possible small difference that a first position determined by the DSRC communication module 20 specifically in step 802 has against a first position in the form of the location position of the first roadside device 60a in step 807, the (roadside) boundary difference in the roadside Comparison of step 807 is used, for example, 0.1 km less than the (vehicle-side) limit difference used in the vehicle-side comparison of step 805. This ensures that even if the first position determined by the DSRC communication module as a result of the first transaction is stored by the first roadside device 60a Position deviates by up to 100m meters, the second transaction can still be performed by the first roadside device 60a.
It is the second roadside device 60b receiving this second position after the DSRC communication module 20 detects the first communication region 62a of the first roadside device 60a after the first roadside device 60a
the first position, the position difference of the second position and the first position of its positional position available to it determines a distance of 1.4 km, which is significantly greater than the limit of 0.6 km, which is the threshold for the second Transaction is available. Thus, the second roadside device performs a second toll transaction for the use of the second leg of the road 50 on which it is located.

The diversity of these six embodiments does not limit the ability and ability of those skilled in the art, from the disclosure of this document without being inventive, to combine and / or exchange various features of these embodiments without departing from the scope of an inventive subject matter leads to a contradiction to the idea of the invention.
