Intelligent transport systems - After-theft systems for the recovery of stolen vehicles - Part 3: Interface and system requirements in terms of short range communication system

This European Standard focuses on Short Range (SR) Interface/Systems Requirements. SR systems use an interface that allows Detection Equipment to operate some ATSVR functions in the direct line of sight of vehicles.
SR systems enable LEAs in a particular country, to permit LEA personnel to perform actions on vehicles that are within their immediate vicinity. Such actions can include identification of vehicle data or influencing the vehicle from a remote site.
Standards for Automatic Vehicle Identification (AVI) and Automatic Equipment Identification (AEI) are being developed by CEN/TC 278/WG 12 in parallel with ISO/TC 204/WG 4. This ATSVR specification does not prejudice those standards and does not seek to establish parameters for future AVI/AEI standards. DSRC and AVI Standards are seen as basic technology blocks for types of short range ATSVR.
This part of EN 15213 describes the structure, bit arrangements, number representation and coding of message elements that are typically transmitted as data. There is no requirement to make the messages as short or as effective as possible. Emphasis is placed on making them as clear and unambiguous as possible.
For Short Range Communications, where there is very little time available for the transfer of data between passing vehicles and detection equipment, only a subset of the message elements described in this document can be transmitted. Therefore, in these cases, the data lengths are reduced to an absolute minimum.
Data elements such as times, dates, or geographical coordinates need not be transmitted because the ATSVR consists of various equipment elements that communicate and interact through various interfaces in accordance with standard procedures and protocols facilitating the recovery of stolen vehicles. These processes may involve a human operator.
ATSVR elements include the OBE installed in the vehicles, a range of Detecting Equipment and one or more System Operating Centres. One or more supporting Infrastructure Networks provides communications to support the ATSVR. The ATSVR location function may also include one or more supporting Position Reference Sources.
Some Short Range devices may be triggered by or may use long range communications and vice versa.
Some Interfaces are not within the scope of this EN. These comprise interfaces to or from sensors, actuators and human operators; from position reference sources, e.g. GPS, LEAs internal interfaces, etc.
Detection Equipment "knows" the time; in case of stationary equipment, it "knows" its coordinates, etc. The Detection Equipment may concatenate these data elements to the data coming from the vehicle, when sending a complete data set to ATSVR System Operating Centres or to LEA as described in other parts of this EN.
Wherever possible the same specifications, data structures, contents, and definitions have been used throughout this EN. This EN does not seek to define the requirements or actions of the various human elements of the ATSVR, but it does aim to identify the interactions and interfaces that exist amongst the equipment and human elements operating within the system.

Intelligente Transportsysteme - Systeme für das Wiederfinden gestohlener Fahrzeuge - Teil 3: Schnittstellen- und Systemanforderungen für Nahbereichskommunikationssysteme

Diese europäische Norm konzentriert sich auf Schnittstellen /Systemanforderungen für die Nahbereichskommunikation. Nahbereichs  bzw. SR Systeme (en: Short Range systems) nutzen eine Schnittstelle, die ermöglicht, dass Erkennungseinrichtungen einige ATSVR Funktionen bei direkter Sicht auf Fahrzeuge ausführen können.
SR Systeme ermöglichen es, dass das Personal von Strafverfolgungsbehörden in einem bestimmten Land Aktionen in Bezug auf Fahrzeuge ausführen kann, die sich in der unmittelbaren Nähe befinden. Derartige Aktionen können die Identifikation von Fahrzeugdaten oder die Einflussnahme auf das Fahrzeug aus der Ferne umfassen.
Parallel zu ISO/TC 204/WG 4 werden vom CEN/TC 278/WG 12 Normen zur automatischen Fahrzeug-identifikation (AVI) und automatischen Geräte Erkennung (AEI) erarbeitet. Diese ATSVR Spezifikation lässt diese Normen unberührt und legt keine Parameter für zukünftige AVI /AEI Normen fest. DSRC  und AVI Normen werden als Basistechnologieblöcke für Arten von Nahbereichs ATSVR betrachtet.
Dieser Teil von EN 15213 beschreibt die Struktur, Bitanordnungen, Zahlendarstellung und Codierung von Mitteilungselementen, die üblicherweise als Daten übertragen werden. Es besteht nicht die Anforderung, die Mitteilungen möglichst kurz oder effektiv zu halten. Es wird jedoch Wert darauf gelegt, sie so deutlich und eindeutig wie möglich zu gestalten.
In der Nahbereichskommunikation, wo nur sehr wenig Zeit zum Transfer von Daten zwischen vorbeifahrenden Fahrzeugen und Erkennungseinrichtungen zur Verfügung steht, kann nur eine Teilgruppe der in diesem Dokument beschriebenen Mitteilungselemente übertragen werden. Daher sind die Datenlängen in diesen Fällen auf ein absolutes Mindestmaß beschränkt.
Datenelemente wie Zeit, Daten oder geographische Koordinaten brauchen nicht übertragen zu werden, da das ATSVR aus verschiedenen Elementen besteht, die über verschiedene Schnittstellen nach Standard¬prozeduren und  protokollen kommunizieren und interagieren, um das Wiederfinden gestohlener Fahrzeuge zu ermöglichen. Diese Prozesse können einen Menschen als Bediener umfassen.
ATSVR Elemente umfassen die fahrzeugseitig installierte Einrichtung (OBE), eine Reihe von Erkennungsein-richtungen sowie ein oder mehrere Systembetriebszentren. Ein oder mehrere unterstützende Infrastruktur¬netze stellen Kommunikationsmöglichkeiten zur Unterstützung des ATSVR bereit. Die Ortungsfunktion des ATSVR kann außerdem eine oder mehrere unterstützende Positionsreferenzquellen umfassen.
Einige Nahbereichsgeräte können durch Weitbereichskommunikation ausgelöst werden bzw. diese nutzen oder umgekehrt.
Einige Schnittstellen liegen nicht innerhalb des Anwendungsbereichs dieser Technischen Spezifikation. Dazu gehören Schnittstellen mit Sensoren, Stellgliedern und menschlichen Bedienern, mit Positionsreferenzquellen, z. B. GPS, interne Schnittstellen der Strafverfolgungsbehörden usw.
Erkennungseinrichtungen ist die Zeit „bekannt“; ortsfesten Geräten sind ihre Koordinaten „bekannt“ usw. Beim Senden eines vollständigen Datensatzes an ATSVR Systembetriebszentren oder Strafverfolgungsbehörden können die Erkennungseinrichtungen diese Datenelemente mit den vom Fahrzeug empfangen Daten verketten, wie in anderen Teilen dieser Technischen Spezifikation beschrieben.
Wo möglich, wurden innerhalb dieser Norm die gleichen Spezifikationen, Datenstrukturen, Inhalte und Definitionen verwendet. Mit dieser Technischen Spezifikation sollen nicht die Anforderungen oder Aktionen der verschiedenen menschlichen Elemente des ATSVR definiert werden, sondern die Interaktionen und Schnittstellen aufgezeigt werden, die zwischen den Geräten und menschlichen Elementen innerhalb des Systems vorhanden sind.

Inteligentni transportni sistemi - Sistemi za odkrivanje ukradenih vozil - 3. del: Vmesnik in zahteve za potrebe sistema za komunikacijo kratkega dosega

Ta evropski standard se osredotoča na vmesnik/zahteve za potrebe sistema kratkega dosega (SR). Sistemi SR uporabljajo vmesnik, ki omogoča, da oprema za detekcijo uporablja nekatere funkcije ATSVR v neposredni liniji pogleda vozil. Sistemi SR omogočijo organom pregona v posamezni državi, da izvedejo dejanja na vozilih, ki so v njihovi neposredni bližini. Taka dejanja lahko vključujejo identifikacijo podatkov vozila ali upravljanje vozila z oddaljene lokacije. Standarde za samodejno identifikacijo vozila (AVI) in samodejno identifikacijo opreme (AEI) pripravlja odbor CEN/TC 278/WG 12 v skladu z ISO/TC 204/WG 4. Ta specifikacija ATSVR ne vpliva na zgoraj omenjene standarde in njen namen ni določitev parametrov za prihodnje standarde AVI/AEI. Standardi DSRC in AVI se obravnavajo kot tehnološka osnova za vrste ATSVR kratkega dosega. Ta del EN 15213 opisuje sestavo, razporeditev bitov, prikaz številk in kodiranje elementov poročila, ki se običajno prenašajo v obliki podatkov. Teh poročil ni potrebno oblikovati tako, da so kar najbolj kratka ali učinkovita. Biti morajo čim bolj jasna in nedvoumna. Pri sistemih za komunikacijo kratkega dosega, kjer je na voljo malo časa za prenos podatkov med mimovozečimi vozili in opremo za detekcijo, se lahko prenese le podmnožica elementov poročila, ki je opisana v tem dokumentu. Zato je v teh primerih dolžina podatkov zmanjšana na absolutni minimum. Prenašanje elementov poročila, kot so čas, datumi ali geografske koordinate, ni potrebno, ker ATSVR sestavljajo različni elementi opreme, ki si posredujejo podatke in medsebojno vplivajo prek različnih vmesnikov v skladu s standardnimi postopki in protokoli, ki olajšujejo odkrivanje ukradenih vozil. Ti postopki morda vključujejo človeškega izvajalca. Elementi ATSVR vključujejo OBE, ki je vgrajen v vozila, vrsto opreme za detekcijo in enega ali več centrov za upravljanje sistema. Eno ali več podpornih infrastrukturnih omrežij zagotavlja komunikacijo za podporo ATSVR. Funkcija položaja ATSVR lahko vključuje tudi enega ali več podpornih referenčnih virov o položaju. Nekatere naprave kratkega dosega lahko sproži komunikacija dolgega dosega ali uporabljajo komunikacijo dolgega dosega in obratno. Nekateri vmesniki niso zajeti v področje uporabe tega standarda. Ti vključujejo vmesnike za dostop do senzorjev, sprožilnikov in vmesnike za človeške izvajalce; iz referenčnih virov o položaju, npr. GPS, notranjih vmesnikov organov pregona itd., oprema za detekcijo »prebere« čas; v primeru stacionarne opreme »pozna« njene koordinate itd. Oprema za detekcijo lahko pri pošiljanju popolnega podatkovnega sklopa centrom za upravljanje sistema ali organom pregona te podatkovne elemente poveže s podatki, ki prihajajo iz vozila, kot je opisano v drugih delih tega standarda. Kjer je možno, so bile v tem standardu uporabljene enake specifikacije, podatkovne sestave, vsebine in definicije. Namen tega standarda ni določanje zahtev ali delovanja različnih človeških elementov ATSVR, ampak opredelitev medsebojnih vplivov in povezav med opremo in človeškimi elementi, ki upravljajo sistem.

Overview

EN 15213-3:2013 is a CEN European Standard that specifies interface and system requirements for short range communication (SR) within After-Theft Systems for Vehicle Recovery (ATSVR). It defines how On‑Board Equipment (OBE), Detection Equipment (DE) and System Operating Centres (SOC) exchange message elements over short-range links (line‑of‑sight or DSRC/AVI-like technologies). The standard emphasizes clear, unambiguous message structure, bit arrangements and coding for SR telegrams, and addresses practical constraints when only very short contact times are available between passing vehicles and roadside detectors.

Key topics and technical requirements

• Scope and architecture
  • SR interface requirements for local, near‑vehicle interactions enabling law enforcement to identify or influence nearby vehicles.
  • Defines ATSVR elements: OBE, DE, SOC, supporting infrastructure and optional position sources.
• Message structure & data elements
  • Prescribes structure, bit arrangements, number representation and coding for message elements transmitted in SR telegrams.
  • Prioritizes clarity and unambiguous encoding over minimizing message length.
  • Provides a reduced subset and shortened data lengths for cases with limited contact time.
• Functional operations
  • Identification function (vehicle/OBE identification).
  • Remote activation, deactivation and optional remote degradation functions.
  • Theft indication and interaction sequences for SR detection (consulting and signalling modes).
• Operational constraints
  • Acknowledges DE may append contextual data (time, location) so some elements need not be sent by the OBE.
  • Notes possible interplay between SR and long range mechanisms (triggering or complementing each other).
• Interoperability focus
  • Uses common definitions and data structures across EN 15213 parts to enable national and international interoperability between SOCs and LEAs.

Applications and users

• Who uses it
  • ITS product vendors, OBE/DE manufacturers, system integrators, vehicle OEMs, law enforcement agencies (LEAs), SOC operators, test laboratories and standards bodies.
• Typical applications
  • Roadside detection of stolen vehicles via DSRC/short‑range links.
  • Local identification of vehicle data by police or roadside units.
  • Remote commands in the immediate vicinity (identification, activation/deactivation, optional engine performance degradation).
  • Integration of SR detection with broader ATSVR workflows managed by SOCs.

SR systems enable LEAs in a particular country, to permit LEA personnel to perform actions on vehicles that are within their immediate vicinity. Such actions can include identification of vehicle data or influencing the vehicle from a remote site. Standards for Automatic Vehicle Identification (AVI) and Automatic Equipment Identification (AEI) are being developed by CEN/TC 278/WG 12 in parallel with ISO/TC 204/WG 4.

5.1.1 Detection by CONSULTING Architecture Diagram This diagram depicts one subset of the general ATSVR Architectural Diagram. It shows the Operating Centres, Communication Network including the DE, and the vehicle with its OBE together with data streams and interfaces.
Key 1)
Theft shall be reported to the LEA SOC either directly or via an ATSVR SOC. 2) "Reported to be stolen" information is kept by the ATSVR SOC. 3) When the Theft Registration has been reported, the DE is activated (updating the DE data file) either at LEA SOC before being deployed, or remotely via Long Range Infrastructure Network. 4) DE interrogates the OBEs of vehicles in the vicinity ("consulting"). 5) OBE sends back the VIN and theft status of the vehicle (or encrypted information from which VIN and status can be derived). 6) DE compares data from the OBE with its data file of stolen vehicles and determines whether the vehicle is reported as stolen.
7) If the DE has determined that the vehicle status information has to be updated, it sends the appropriate data to the OBE.
8) Acknowledgement that OBE has been updated is reported back and logged in the DE.
9) Data of the detected vehicle together with status information is sent to the LEA SOC.
10) This information is subsequently routed to the ATSVR SOC to update their files.
11) Beyond these technical requirements: LEA SOC or the ATSVR SOC may take appropriate action. Figure 1 — Detection by CONSULTING Architecture Diagram SIST EN 15213-3:2013

This function is especially needed for controls at the roadside, border, harbour, entrance to a parking area, etc. using stationary DEs. In order to support these activities a fast identification-function is provided. The transmission of the VIN and the theft-status is sufficient. All other relevant data about the vehicle can be obtained from the vehicles database. The theft-status in the OBE can be changed via the remote activation function.
Transmission of the theft-status from the OBE to the DE is important because it permits the use of simple DE without connections to a central database of stolen vehicles. It is a pre-requisite that the theft-status of the OBE is up-to-date. Table 1 shows the main events for the case of detection by consulting.

5.1.3 Detection by SIGNALLING Architecture Diagram
This diagram depicts another subset of the general ATSVR Architectural Diagram. It shows the System Operating Centre(s), the Communication Network(s), including the Detection Equipment, and the Vehicle together with data streams and interfaces. SIST EN 15213-3:2013

Key 1) Theft shall be reported to the LEA SOC either directly or via an ATSVR SOC. 2) "Reported to be stolen" information is kept by the ATSVR SOC. 3) LEA and some specially authorised organisations have access to this file. 4) ATSVR SOC pre-activates the OBE through the Long Range Infrastructure Network. 5) Theft status information is set in the OBE. 6) When in the vicinity of a DE sending interrogation telegrams, the OBE interprets them as a wake up and; 7) OBE starts signalling, i.e. sends periodically the VIN and theft status of the vehicle. 8) Hand held DEs display data from the OBE and mark them as coming from a stolen vehicle.
9) Stationary DEs send the appropriate data to the LEA SOC and/or ATSVR SOC.
10) Beyond these technical requirements: The LEA SOC, the ATSVR SOC or an agent reading the DE information may take appropriate action.
11) In case of vehicle recovery, the OBE's stolen status information shall be reset. Some special equipment using the same DE-OBE-interface may be used. Excellent cryptography shall be used to perform this action. Figure 2 — Detection by SIGNALLING Architecture Diagram The various parts of the system work as follows: a) Theft shall be reported to the LEA SOC either directly or via an ATSVR SOC.
b) Information is put into a file of stolen vehicles, e.g. the stolen vehicle register for the country where the theft takes place and the European central file. The file contains information such as the VIN, make of vehicle, type, colour, license plate number, country of registration of the vehicle, date and time of theft. c) LEA and some specially authorised organisations have access to these files.
EXAMPLE 1 By a point-to-point connection via GSM using e.g. short messages. EXAMPLE 2 By Short Range Communication when the vehicle passes a DE. EXAMPLE 3 By broadcast messages via FM radio using the traffic message channel.
e) This information will "pre-activate" the OBE: The "theft status bit" is set, but transmissions to the outside world ("signalling") will not yet occur. See points f) and g). f) When the "pre-activated" vehicle passes a stationary or mobile detection unit which is sending some short range communication telegrams and if the OBE receives this information, then it interprets it as a wake up command for its signalling device.
g) The OBE energises transmissions for the following vehicle information:
1) "stolen" information; 2) make, type and colour;
3) licence plate number; 4) country of registration;
5) VIN.
h) Hand held readers and/or stationary detection equipment may receive these signals, issue an alarm and may display the signals in an appropriate form in the machine to human interface specifications.
i) Stationary equipment reports the detection of the stolen vehicle to the LEA SOC and/or to the ATSVR SOC. Hand held equipment may also have provisions for sending this information to the LEA and/or ATSVR SOC.
j) After reception, the agent using the DE or the ATSVR SOCs or the LEA may perform appropriate actions to recover the vehicle. These actions are not within the scope of this EN and are given only for clarification.
k) After recovery of the vehicle, the OBE shall be reset to the not-stolen state. If for this purpose the same equipment and interface between the DE and the OBE is used, then very good cryptographic features shall be employed to prevent misuse of this critical resetting.
5.1.4 Detection by SIGNALLING Sequence Diagram A prerequisite to Detection by Signalling is that the OBE has been activated by an external source. This activation may come from a mobile or stationary source, which may be local to the vehicle (short-range) or, in most cases, at a distance from the vehicle (transmission via long-range). Once activated, the OBE will transmit signals (hence "signalling") that can be received by ATSVR Detection Equipment located locally, or at a distance from the vehicle. The transmitted signal may contain other relevant information. Table 2
shows the sequence of events for detection by signalling. SIST EN 15213-3:2013

Acknowledgement of the vehicle status • •
Remote OBE Activation “Theft Status” = on
• •
• Detection of the vehicle signalling " Theft Status = on "
• • Report of detection •
•
In this table the activation of the OBE theft-status is done by long-range communications. The beginning of transmitting the signalling telegrams may be dependent upon prior reception of a short range request from a DE in the vicinity of the vehicle. The short-range activation is described in Annex B.
Discrimination is a very important aspect of detecting a stolen vehicle by signalling in situations where the vehicle is surrounded by several other cars. The officer should be able to determine rapidly which of the vehicles is signalling. This should be achieved through visual observation based on knowledge of the vehicle particulars such as make, model, colour and license-plate. When operating in the Signalling Mode, the OBE shall not interfere with the operation of Detection by Consulting equipment. 5.2 Identification Function
The identification function allows the unequivocal identification of a vehicle as being the Registered Stolen Vehicle. This may be by means of a secure process that allows the unique vehicle data to be read e.g. VIN, registration number, theft status, model, colour.
This function is typically required where an authorised person has to identify a possibly stolen vehicle by using a hand-held scanner.

5.3 Remote Activation Function This function is part of Detection by Signalling and Detection by Consulting. The Activation Function switches the OBE Theft Status = ON. Detection by signalling will only be effective if the theft-status in the OBE is set (OBE Theft Status = ON). Reading the theft-status is essential when the DE has no database of Registered Stolen Vehicles.

5.4 Remote Deactivation Function After recovering a stolen vehicle, the OBE Theft Status shall be reset (OBE Theft Status ‘OFF’). This function is complementary to the "Activation" function as it electronically "converts" a stolen vehicle into a "not stolen" vehicle. The design of this function shall be cryptographically secured and only performed by specifically accredited personnel. One possibility of securing the necessary data transfers is to use a very secure algorithm (AES), together with a vehicle specific key that is only stored in the vehicle’s immobiliser and in the manufacturer's data bank. AES has the feature of selectable key length and runs on small micro-controllers. Also, there is no license fee and the algorithm is freely available. Preferably, the deactivation function should employ short range protocols, and the personnel should be in line of sight of the vehicle.
Before deactivation, the vehicle has to be unequivocally identified (see Identification Function). A bi-directional communication with the LEA SOC results in authorising the Deactivation Function. In the Sequence Diagram below it is assumed that the LEA SOC has received the vehicle's unique cryptographic key from a data bank (usually the vehicle manufacturer's data bank
