3.1

platoon

vehicle formation with a common platoon ID and sequence of participants

3.2

platooning

operation of a platoon in which multiple vehicles are driving under coordinated longitudinal control and possibly lateral control

Note 1 to entry: Each vehicle uses forward-vehicle detection by on-board sensors and vehicle to vehicle (V2V) over-the-air communication to exchange information needed to execute the coordinated longitudinal control with the other vehicles in the platoon (see Figure 2).

3.3

leading vehicle

first vehicle in a platoon

3.4

following vehicle

vehicle operating in a platoon behind the leading vehicle and connected using vehicle to vehicle communication

3.5

other vehicle

vehicle that does not participate in the platoon but can potentially affect platoon operations, by performing emergency braking or a cut-in manoeuvre, for example

3.6

potential leading vehicle

vehicle that is not currently in a platoon but is in a position enabling it to potentially become the leading vehicle in the future or a former leading vehicle after leaving the platoon

3.7

potential following vehicle

vehicle that is not currently in a platoon but is in a position enabling it to potentially become the following vehicle in the future or a former following vehicle after leaving the platoon

3.8

join

transition by which one or more vehicle(s) become(s) member(s) of a platoon

3.9

leave

transition by which one or more vehicle(s) separate(s) from its current platoon

3.10

platooning control system

system for operating the platooning operation control function and the platooning manoeuvre control function in a platoon, including the potential leading vehicle and potential following vehicle

3.11

platooning operation control function

function to manage the transitions of vehicles in and out of platoon membership

3.12

platoon management message

vehicle to vehicle communication or vehicle to infrastructure communication message that transmits information relevant to the platooning operation control function

3.13

platooning manoeuvre control function

function to manage the continuous operations of platoon vehicles, including responses to situations such as cut-in and cut-out

3.14

platoon control message

vehicle to vehicle communication message that transmits information relevant to the platooning manoeuvre control function

3.15

vehicle to infrastructure communication

communication between vehicle and devices such as a roadside unit of infrastructure or mobile phone base station, but excluding vehicles

3.16

back office

infrastructure system to support platoon operation, such as platoon planning and demand matching to start the platoon, and route management and the charge/payment process from the operators, such as shippers and fleet operators

3.17

time gap

time needed to travel a distance equal to the clearance gap between the rear surface of the preceding vehicle and the forward surface of the following vehicle at the current vehicle speed

Note 1 to entry: This value is calculated as c/v , where v is the vehicle speed of the following vehicle and c isthe clearance between the head of the following vehicle and the tail of the leading vehicle.

3.18

heavy goods vehicle

truck with a gross combination mass (GCM) over 3 500 kg. which is considered as a vehicle according to categories N2 and N3 of WP.29 TRANS/WP.29/78/Rev.6

Note 1 to entry: See Reference [14].
