3.1

ABS

anti-lock braking system

control function, which automatically modulates the pressure producing the braking forces at the wheels to limit the degree of wheel slip, or a system that provides an anti-lock braking function

3.2

ASR

anti-spin regulation

control function, which automatically modulates the engine torque or the pressure producing the braking forces at the wheels to limit the degree of wheel spin, or a system that provides an anti-spin control

3.3

axle group

assembly of two or more consecutive axles considered together in determining their combined load effect

3.4

centre-axle towed vehicle

towed vehicle (3.19) equipped with a rigid towing device, and in which the axle(s) is (are) positioned close to the centre of gravity of the vehicle

3.5

converter towed vehicle

dolly unit that couples to a semi towed vehicle (3.18) with a fifth-wheel coupling (3.8) and thereby “converts” the semi towed vehicle to a full towed vehicle (3.9)

3.6

EBS

braking system in, which control is generated and processed as an electrical signal in the control transmission

3.7

ECU

electronic control unit

electronic item consisting of a combination of basic parts, subassemblies, and assemblies packaged together as a physically independent entity

3.8

fifth-wheel coupling

link between a towing vehicle (3.22) and a towed vehicle (3.19) , designed for towing a semi towed vehicle (3.18)

3.9

full towed vehicle

towed vehicle (3.19) equipped with a towing device, which can move vertically (in relation to the towed vehicle), and in which the axle(s) is (are) positioned farther from the centre of gravity of the vehicle

3.10

gateway

unit connecting different networks or parts of one network and performing any necessary protocol translation

3.11

link towed vehicle

towed vehicle (3.19) with a fifth-wheel coupling (3.8) , designed for towing a semi towed vehicle (3.18)

3.12

network segment

3.17

ROP

roll-over prevention

roll-over protection

control function to prevent roll-over situations of a vehicle

Note 1 to entry: ROP is part of a VDC (3.23) function.

3.18

semi towed vehicle

towed vehicle (3.19) , which is designed to be coupled to a semi towed vehicle towing vehicle and to impose a substantial part of its total weight on the towing vehicle (3.22)

3.19

towed vehicle

non-power-driven road vehicle, which, on account of its design and appointments, is used to transport persons or goods and is intended to be towed by a motor vehicle

3.20

towing full towed vehicle

towed vehicle (3.19) equipped with a towing device, which can move vertically (in relation to the towed vehicle), and in which the axle(s) is (are) positioned less close to the centre of gravity of the vehicle that is capable of towing another vehicle

3.21

towing semi towed vehicle

towed vehicle (3.19) , which is designed to be coupled to a semi towed vehicle towing vehicle and to impose a substantial part of its total weight on the towing vehicle (3.22) that is capable of towing another vehicle

3.22

towing vehicle

motor vehicle or non-power-driven vehicle, which tows a succeeding vehicle

3.23

VDC

vehicle dynamic control

control function as part of the braking system that reacts to stabilize the vehicle during dynamic manoeuvres

Note 1 to entry: VDC has the possible sub-functions ROP (3.18) and YC (3.25) .
