1 This Regulation lays down measures for the implementation of Regulation (EU) 2024/1257, with regard to the following: (a) on-board monitoring (OBM) systems including their sensors and driver warning systems; (b) on-board fuel and electric energy consumption monitoring (OBFCM) devices; (c) the format and data and off-board communication methods for the environmental vehicle passport (EVP); (d) methods for in-vehicle display of environmental data about the vehicle type and the environmental performance of the individual vehicle; (e) methods and procedures to establish the absence of manipulation devices and manipulation strategies.

2 This Regulation applies to the motor vehicles belonging to the following vehicle categories: (a) M1 and N1; (b) N2 designated as ‘Euro 7ext’ and ‘Euro 7Gext’ in accordance with Article 5 of Regulation (EU) 2024/1257.

For the purpose of this Regulation, the following definitions shall apply: (1) ‘OBM data’ means data produced by the ‘on-board monitoring system’ or ‘OBM system’, including battery durability data; (2) ‘OBM trip’ means each period of vehicle operation that starts with the activation of the propulsion system and ends with the deactivation of the propulsion system. For the purpose of determining the end of an OBM trip, sequences of engine shut-off events followed by an engine re-start commanded by the vehicle control system (as a result of the operation of stop-start systems, hybrid vehicle control or automatic stall recovery) shall not be considered a deactivation of the propulsion system; (3) ‘OBM trip data’ means OBM data that relate to a particular OBM trip; (4) ‘OBM hash function’ means a standard mathematical algorithm implemented on-board the vehicle that takes a set of OBM data and converts it into a string of characters with a fixed predetermined length, and whose properties can be used to randomly select OBM data to be transmitted over the air, or to verify the integrity of the transmission of OBM data while preserving their anonymous nature; (5) ‘OBM hash value’ means the output of the OBM hash function for a given input; (6) ‘OBM data schema’ means a fixed structure for data that are input to the OBM hash function; (7) ‘generic scan tool’ means an external test equipment used for standardised off-board communication with the vehicle’s electronic control systems; (8) ‘service tool’ means a specialised external test equipment used to perform manufacturer-defined service operations via communication with the vehicle’s electronic control systems; (9) ‘QR code’ means a machine-readable matrix code that links to information; (10) ‘Auxiliary Emission Strategy’ or ‘AES’ means an emission strategy that becomes active and replaces or modifies a BES for a specific purpose and in response to a specific set of ambient or operating conditions and only remains operational as long as those conditions exist; (11) ‘Base Emission Strategy’ or ‘BES’ means an emission strategy that is active throughout the speed and load operating range of the vehicle unless an Auxiliary Emission Strategy is activated.

1 The manufacturer shall ensure that the OBM systems perform the functions as laid down in Articles 4 to 10 by means of hardware and software installed in the vehicle for as long as the vehicle is in use.

2 The manufacturer shall ensure that OBM systems comply with the OBM data requirements as laid down in Annex I.

1 The manufacturer shall ensure that the excess exhaust emissions driver warning system (EEEDWS) performs the following functions: (a) assign the OBM monitoring status of NOx and particulate matter (PM) in accordance with Article 5; (b) provide driver warnings in accordance with Annex II as long as one or more of the exhaust emissions monitoring statuses is in ‘Error’ status; (c) if driver warnings referred to in point (b) are not acted upon within the period specified in Annex II, limit vehicle use through harmonised inducement methods described in that Annex until appropriate repairs are carried out.

2 The EEEDWS may assign the monitoring status for exhaust emissions other than NOx and PM using a generic OBM monitoring status parameter. Points (b) and (c) of paragraph 1 shall apply with regard to the generic OBM monitoring status parameter.

1 The manufacturer shall ensure that each OBM monitoring status is individually set. Each OBM monitoring status may be updated once after the end of each OBM trip as one of the following: (a) ‘Normal’ status, which shall indicate that the emissions control systems installed on the vehicle are judged to be functioning adequately and the OBM system has high confidence in the accuracy of OBM monitoring; (b) ‘Intermediate’ status, which shall indicate that the OBM system is unable to make a conclusive assessment of the status of the relevant emissions control systems or that an increased uncertainty in OBM monitoring values may exist; (c) ‘Error’ status, which shall indicate that faults or tampering that prevent adequate emissions control or monitoring and justify a repair have been identified. As an indicative target when designing the OBM system, the manufacturer shall ensure that if the OBM determines that the vehicle may be in a state where its exhaust emissions as evaluated via a real-driving emissions (RDE) or other applicable in-service conformity test would be equal or higher than 2,5 times the applicable emission limit, the ‘Error’ status shall be activated.

2 The manufacturer may use any available data or engineering approach which allows the EEEDWS to determine the monitoring status of a pollutant, based on the expected exhaust emissions or performance of emissions control systems of a vehicle.

1 The manufacturer shall ensure that, immediately after the end of each OBM trip, the OBM system performs a calculation of all exhaust emissions of NOx in mg/km for the whole duration of the OBM trip, uninterruptedly. That calculation shall be made by dividing the estimated total mass emissions of NOx during that OBM trip by the total distance driven during that OBM trip.

2 The calculation referred in paragraph 1 shall provide a reasonable indication of real-world exhaust emissions of NOx based upon any of the following elements: (a) measurements performed by on-board sensors; (b) modelled data; (c) a combination of measurements performed by on-board sensors and modelled data.

1 Immediately after the end of each OBM trip, the manufacturer shall ensure that the OBM system calculates the parameters listed in part A of Annex I and Appendices 2 to 6 of part C of Annex I in accordance with the specifications laid down in that Annex for the whole duration of the OBM trip, uninterruptedly.

2 The calculation referred to in paragraph 1 shall be based upon measurements performed by on-board sensors, upon modelled data or a combination thereof and shall provide a reasonable indication of the true values of the signals or parameters.

1 Immediately after the calculations described in Articles 6 and 7 are completed, the manufacturer shall ensure the OBM system calculates the hash value for the OBM trip data in accordance with part B of Annex I.

2 The manufacturer shall ensure that the OBM system performs on-board processing of all other OBM data in accordance with part B of Annex I.
