the DE 10 2006 032 468 B3 describes adaptive data volume in the transmission of data for a central geo object recognition. Known toll systems are implemented either on the basis of a so-called "thin client solution" or on a "thick client solution".

With the thin client solution, mainly GNSS data is collected from the on-board units and sent to the back office, where the back office carries out the road and tariff zone identification for calculating the toll.

In the thick client solution, the on-board units calculate the street and tariff zone identification and, if necessary, a distance measurement and, if necessary, the toll fee calculation and the calculated route, street and tariff zone identification are transmitted to the back office, whereby the on-board units complex in construction and consequently expensive.

The object of the present invention is to provide a method for detecting a toll on a motor vehicle.

The object is solved by the features of independent claim 1.

The procedure comprises the following procedural steps:
The following is carried out in method step S10-1: The toll collection device or the toll on-board unit recognizes entering or driving into a tariff zone. A country or a toll area can have one or more tariff zones. In method step S10-2, a query is made as to whether driving into a tariff zone has been detected; if so, method step S10-3 is processed; if no, method step S10-1 is then repeated.

The following is carried out in method step S10-3: The toll on-board unit carries out a provisional registration of kilometers traveled within the currently traveled tariff zone with the available GNSS-enabled accuracy. In method step S10-4, all GNSS data is temporarily stored by the toll on-board unit for a limited time. In method step S10-5, a query is made as to whether departure from the currently traveled tariff zone has been detected; if so, method step S10-6 is processed; if no, method steps S10-3 and S10-4 are repeated.

The following is carried out in method step S10-6: When leaving the tariff zone, the toll on-board unit 10 saves the record in the form of a data record, about the GNSS data received within the tariff zone and about the provisionally registered kilometers driven within the fare zone.

1. a. eine ID der Tarifzone
2. b. Einfahrt- oder Eingangszeit in UTC
3. c. Ausfahrt- oder Ausgangszeit in UTC
4. d. gefahrene Strecke
5. e. Zeit und/oder Stecke der Bewegung ohne GNSS fix
6. f. Angepasste Anzahl von GNSS-Daten

The stored record may also include one or more of the following list:

1. a. an ID of the tariff zone
2. b. Entry or entrance time in UTC
3. c. Exit or exit time in UTC
4. i.e. driven route
5. e. Fix time and/or distance of movement without GNSS
6. f. Adjusted number of GNSS data

UTC stands for coordinated world time, derived from English "Coordinated Universal Time" and French "Temps universel coordonne", the world time valid today.

ID stands for an identifier (also identifier or ID for short). An identifier is an artificially assigned feature for the unique identification of an object, in this case the tariff zone.

The amount of GNSS data that is transmitted to check the preliminary route measurement can be automatically adjusted depending on the driving dynamics, the driving profile, route and zone properties or other conditions.

In method step S10-7, a query is made as to whether a trigger event for a data transmission was detected; if so, method step S10-8 is processed; if no, method step S10-1 is processed.

In method step S10-8, the data record is sent from the toll on-board unit 10 to the data center.

The method steps S10-1 to S10-8 are processed by the toll on-board unit 10 and one or more of the method steps S10-1 to S10-8 can represent a preliminary driving data calculation, for example.

The following method steps S100-1 to S100-6 are processed by the data center.

The following is carried out in method step S100-1: The data center 100 checks the data record sent by the toll on-board unit 10, for example by means of map matching.

Map comparison, map adjustment or map matching is a process that compares the position of an object measured by a location with the location information on a digital map.

If the geographic coordinates measured using a positioning method are mapped directly to the coordinate system of a digital map, the true position of the object on the map can deviate from the position of the object shown on the map.

In method step S100-2, a query is made as to whether additional data is required; if so, method step S100-3 is processed; if no, method step S100-4 is processed.

In method step S100-3 further data records are requested.

In method step S100-4, the transmitted data record is confirmed.

In method step S100-5, a final toll calculation takes place using the further data records.

In method step S100-6, the final toll calculation may be sent to the on-board toll unit 10

• Geographische Breite des Kraftfahrzeuges,
• Geographische Länge des Kraftfahrzeuges,
• Geschwindigkeit des Kraftfahrzeuges,
• Richtung der Bewegung des Kraftfahrzeuges,
• relative Zeitinformation, d. h. eine Abweichung zum vorher gehenden Datensatz, oder
• absolute Zeitinformation

In order to be able to carry out map matching and/or a double check in the proxy or in the data center, the following data is recorded:

• geographical latitude of the motor vehicle,
• geographic longitude of the motor vehicle,
• speed of the motor vehicle,
• direction of movement of the motor vehicle,
• relative time information, ie a deviation from the previous record, or
• absolute time information

The term proxy refers to the term used in the context of toll systems for an instance upstream of the back office, which organizes communication with the toll on-board units in the field.

• VDOP, Vertical DOP, Vertikalrichtung,
• HDOP, Horizontal DOP, Horizontalrichtung,
• EHPE, Expected Horizontal Position Error,
• PDOP, Positional DOP, Positionsgenauigkeit.

If additional data and timestamps are required for map matching and/or a double check, e.g.:

• VDOP, Vertical DOP, Vertical Direction,
• HDOP, Horizontal DOP, Horizontal Direction,
• EHPE, Expected Horizontal Position Error,
• PDOP, Positional DOP, Positional Accuracy.

Dilution of Precision (DOP) is a measure of the spread of measured values in satellite navigation systems.

Since DOP depends on the relative position of the satellites to each other and to the observer, one also speaks of geometric dilution of precision (GDOP), depending on the number of satellites used to determine the position and the UTC time.

The GNSS data can be transmitted using a compression algorithm to minimize the size of the data sent to the data center 100 .

The present invention is characterized in that a combined method is used, in which a provisional toll fee calculation in the form of a provisional driving data calculation is carried out by the toll on-board unit (OBU) and a final calculation in the back office (BO) , based on the data transmitted by the on-board unit, which may include preliminary calculations or raw or primary data collected, such as GNSS data.

The method of the present invention leads to a highly accurate, robust and reliable registration method with optimized communication costs for the toll calculation of the toll system and can be used in the toll calculation for motor vehicles.

Reliability is ensured by the fact that even in cases where the back office is overloaded for certain reasons, the toll on-board unit continues to record and register the tariff zones and the kilometers driven autonomously.

According to the invention, it is also provided that GNSS data is transmitted to the data center to check the provisional driving data calculation.

According to the invention, the scope of the GNSS data to be transmitted is automatically adjusted as a function of driving dynamics and/or a route property and/or a zone property.

According to the invention, provision is made for the transmitted provisional driving data calculation to be checked by the data center.

As a result, the fail-safety and reliability of the toll system can be increased.

In a preferred embodiment it is provided that the transmission of the calculated provisional driving data calculation to the data center is started by a trigger event.

As a result, the data transmission volume can advantageously be reduced.

In a preferred embodiment it is provided that a distance covered by the motor vehicle or a journey time covered by the motor vehicle or a departure from a tariff zone is used as the trigger event.

According to one aspect that is not claimed, a toll collection device is provided for collecting a toll on a motor vehicle, comprising: a locating unit, which is designed to collect driving data on at least one route covered by the motor vehicle, a computer unit, which is designed to use the recorded driving data calculate a preliminary driving data calculation; and an interface unit, which is designed to transmit the calculated provisional driving data calculation to a data center.

In an advantageous, non-claimed embodiment, it is provided that the computer unit is designed to detect driving on a toll road section and to start a calculation method for calculating the provisional toll fee bill.

As a result, it can be advantageously achieved that computing power is saved and a toll calculation is only started if a toll road section or tariff zone is driven on.

In a further preferred, non-claimed embodiment, it is provided that the computer unit is designed to store the recorded driving data and the interface unit is designed to transmit the driving data to the data center.

This makes it easy to facilitate a final toll calculation in the data center using the transmitted driving data or to verify the provisional toll calculation using the transmitted driving data.

In a further preferred, non-claimed embodiment, it is provided that the locating unit is designed to detect position data transmitted by a navigation satellite system and to determine the driving data using the position data.

By determining the driving data using the position data, the position accuracy of the position determination, as carried out by the locating unit, can advantageously be improved.

In a further preferred, non-claimed embodiment, it is provided that the locating unit is designed to determine the driving data using tachographic data.

As a result, the position determination can advantageously be continued even in the event of a short-term failure of the navigation satellite system.

In a further preferred, non-claimed embodiment, it is provided that the computer unit is designed to calculate a provisional distance measurement and/or a provisional road identification and/or a provisional tariff zone identification and/or a provisional toll fee calculation as the provisional driving data calculation.
