Appendix 12 ADAPTOR FOR M 1 AND N1 CATEGORY VEHICLESF1F2F3

To Be Defined

Vehicle Unit

The adaptor shall provide a connected VU with secured motion data permanently representative of vehicle speed and distance travelled.

The adaptor is only intended for those vehicles that are required to be equipped with recording equipment in compliance with this Regulation.

It shall be installed and used only in those types of vehicle defined under (rr), where it is not mechanically possible to install any other type of existing motion sensor which is otherwise compliant with the provisions of this Annex and its Appendixes 1 to 11.

The adaptor shall not be mechanically interfaced to a moving part of the vehicle, as required by Appendix 10 of this Annex (section 3.1), but connected to the speed/distance impulses which are generated by integrated sensors or alternative interfaces.

A type approved motion sensor (according to the provisions of this Annex, section VIII - Type approval of recording equipment and tachograph cards) shall be fitted into the adaptor housing, which shall also include a pulse converter device inducing the incoming pulses to the embedded motion sensor. The embedded motion sensor itself shall be connected to the VU, so that the interface between the VU and the adaptor shall be compliant with the requirements set out in ISO 16844-3.

The adaptor shall include the following functions:

• interfacing and adapting the incoming speed pulses,

• inducing the incoming pulses to the embedded motion sensor,

• all functions of the embedded motion sensor, providing secured motion data to the VU.

The adaptor shall not be security certified according to the motion sensor generic security target defined in Appendix 10 of this Annex. Security related requirements specified in section 4.4 of this Appendix shall apply instead.

The recording equipment of any vehicle fitted with an adaptor must comply with all the provisions of this Annex, except otherwise specified in this Appendix.

When an adaptor is installed, the recording equipment includes cables, the adaptor (instead of a motion sensor), and a VU (001).

The detection of events and/or faults function of the recording equipment is modified as follows:

• the ‘ power supply interruption ’ event shall be triggered by the VU, while not in calibration mode, in case of any interruption exceeding 200 milliseconds of the power supply of the embedded motion sensor (066),

• any power supply interruption of more than 200 ms (milliseconds) of the adaptor shall generate a power supply interruption of the embedded motion sensor of equivalent length. The adaptor interrupter threshold shall be defined by the adaptor manufacturer,

• the ‘ motion data error ’ event shall be triggered by the VU in case of interruption of the normal data flow between the embedded motion sensor and the VU and/or in case of data integrity or data authentication error during data exchange between the embedded motion sensor and the VU (067),

• the ‘ security breach attempt ’ event shall be triggered by the VU for any other event affecting the security of the embedded motion sensor, while not in calibration mode (068),

• the ‘ recording equipment ’ fault shall be triggered by the VU, while not in calibration mode, for any fault of the embedded motion sensor (070).

The adaptor faults detectable by the recording equipment shall be those related with the embedded motion sensor (071).

The VU calibration function shall allow to automatically pair the embedded motion sensor with the VU (154, 155).

The terms ‘ motion sensor ’ or ‘ sensor ’ in the VU Security Target in Appendix 10 of this Annex refer to the embedded motion sensor.

The adaptor input interface shall accept frequency pulses representative of the vehicle speed and distance travelled. Electrical characteristics of the incoming pulses are: TBD by the manufacturer . Adjustments accessible to only the adaptor manufacturer and to the approved workshop performing the adaptor installation shall allow the correct interfacing of the adaptor input to the vehicle, if applicable.

The adaptor input interface shall be able, if applicable, to multiply or divide the frequency pulses of the incoming speed pulses by a fixed factor, to adapt the signal to a value in the k factor range defined by this Annex ( 4 000 to 25 000 pulses/km). This fixed factor may only be programmed by the adaptor manufacturer, and the approved workshop performing the adaptor installation.

The incoming pulses, possibly adapted as specified above, shall be induced to the embedded motion sensor, so that each incoming pulse shall be detected by the motion sensor.

The embedded motion sensor shall be stimulated by the induced pulses, thus allowing it to generate motion data accurately representing the vehicle movement, as if it was mechanically interfaced to a moving part of the vehicle.

The identification data of the embedded motion sensor shall be used by the VU to identify the adaptor (077).

The installation data stored in the embedded motion sensor shall be considered to represent the adaptor installation data (099).

The adaptor housing shall be designed so that it cannot be opened. It shall be sealed, so that physical tampering attempts can be easily detected (e.g. through visual inspection, see ADA_035).

It shall not be possible to remove the embedded motion sensor from the adaptor without breaking the seal(s) of the adaptor housing, or breaking the seal between the sensor and the adaptor housing (see ADA_035).

The adaptor shall ensure that motion data may only been processed and derived from the adaptor input.

The adaptor shall be fully operational in the temperature range ( TBD by the manufacturer, depending on the installation position ) (159).

The adaptor shall be fully operational in the humidity range 10 % to 90 % (160).

The adaptor shall be protected against over-voltage, inversion of its power supply polarity, and short circuits (161).

The adaptor shall conform to Commission Directive 2006/28/EC ^f1 adapting to technical progress Council Directive 72/245/EEC, related to electromagnetic compatibility, and shall be protected against electrostatic discharges and transients (162).

The adaptor shall meet the protection grade (TBD by the manufacturers, depending upon the installation position) (164, 165).

The colour of the adaptor housing shall be yellow.

A descriptive plaque shall be affixed to the adaptor and shall show the following details (169):

• name and address of the manufacturer of the adaptor,

• manufacturer’s part number and year of manufacture of the adaptor,

• approval mark of the adaptor type or of the recording equipment type including the adaptor,

• the date on which the adaptor has been installed,

• the vehicle identification number of the vehicle on which it has been installed.

The descriptive plaque shall also show the following details (if not directly readable from the outside on the embedded motion sensor):

• name of the manufacturer of the embedded motion sensor,

• manufacturer’s part number and year of manufacture of the embedded motion sensor,

• approval mark for the embedded motion sensor.

Adaptors to be installed in vehicles shall be delivered only to vehicle manufacturers, or to workshops approved by the competent authorities of the Member States and authorised to install, activate and calibrate digital tachographs.

Such approved workshop installing the adaptor shall adjust the input interface and select the division ratio of the input signal (if applicable).

Such approved workshop installing the adaptor shall seal the adaptor housing.

The adaptor shall be fitted as close as possible to that part of the vehicle which provides its incoming pulses.

The cables for providing the adaptor power supply shall be red (positive supply) and black (ground).

The following sealing requirements shall apply:

• the adaptor housing shall be sealed (see ADA_017),

• the housing of the embedded sensor shall be sealed to the adaptor housing, unless it is not possible to remove the embedded sensor without breaking the seal(s) of the adaptor housing (see ADA_018),

• the adaptor housing shall be sealed to the vehicle,

• the connection between the adaptor and the equipment which provides its incoming pulses shall be sealed on both ends (to the extent of what is reasonably possible).

When an adaptor is used, each periodic inspection (periodic inspection means in compliance with Requirement 256 through to Requirement 258 of Chapter VI of Annex 1B) of the recording equipment shall include the following checks (257):

• that the adaptor carries the appropriate type approval markings,

• that the seals on the adaptor and its connections are intact,

• that the adaptor is installed as indicated on the installation plaque,

• that the adaptor is installed as specified by the adapter and/or vehicle manufacturer,

• that mounting an adaptor is authorised for the inspected vehicle.

Recording equipment shall be submitted for type approval complete, with the adaptor (269).

Any adaptor may be submitted for its own type approval, or for type approval as a component of a recording equipment.

Such type approval shall include functional tests involving the adaptor. Positive results to each of these tests are stated by an appropriate certificate (270).

A functional certificate of an adaptor or of recording equipment including an adaptor shall be delivered to the adaptor manufacturer only after all the following minimum functional tests have been successfully passed.
