EPPR secretariat proposal for Amendment of definitions EPPR-24-02 (EPPR Sec.) update of EPPR-19-06 on GTR2 vs VPSD EPPR secretariat proposal for Amendment of definitions in Draft Revision of GTR2 (EPPR-23-33) w.r.t. VPSD Document ECE-TRANS-WP29-2015-110e The definitions for terms which are common in the two documents are tabulated below for comparison. Other terms in Document EPPR-23-33 do not appear ECE-TRANS-WP29-2015-110e

Definitions VPSD ECE-TRANS-WP29-2015-110e Definitions in GTR2 Definitions VPSD ECE-TRANS-WP29-2015-110e Item no. ItemNo. 4.35. ‘powertrain’ means the components and systems of a vehicle that generate power and deliver it to the road surface, including the engine(s), the engine management systems or any other control module, the pollution environmental protection control devices including pollutant emissions and noise abatement systems, the transmission and its control, either a drive shaft or belt drive or chain drive, the differentials, the final drive, and the driven wheel tyre (radius); 1 "Powertrain" means the total combination in a vehicle, of propulsion energy storage system(s), propulsion energy converter(s), the drivetrain(s), providing the mechanical energy at the wheels for the purpose of vehicle propulsion, plus peripheral devices.   Proposal: to take over the VPSD definition

Definitions VPSD ECE-TRANS-WP29-2015-110e Definitions in GTR2 Definitions VPSD ECE-TRANS-WP29-2015-110e Item. No. ItemNo. 4.20 ‘drive train’ means the part of the powertrain downstream of the output of the propulsion unit(s) that consists if applicable of the torque converter clutches, the transmission and its control, either a drive shaft or belt drive or chain drive, the differentials, the final drive, and the driven wheel tyre (radius); 1.3   "Drivetrain" means the connected elements of the powertrain for transmission of the mechanical energy between the propulsion energy converter(s) and the wheels. Proposal: to take over the VPSD definition
