ITS Communica-ons in support of automated driving, or all automa-on shall be based on sensor input?
CooperaHve automaHon pre-­‐requisites & perspecHves
Up to date, the most well-­‐known automated car demos have been sensor based (Google car, VisLab car, etc.). CooperaPve automaPon demos have mostly focused on truck use cases (highway platooning).
The obvious pre-­‐requisite is for cooperaPve ITS to be widely deployed before the maturaPon of fully automated driving technology. Otherwise, it is much more difficult to replace exisPng technology.

CooperaHve vs Sensor-­‐based automaHon
Sensor-­‐based automa<on:
Coopera<ve ITS automa<on:
✴up to 2-­‐3 sec forward planning
✓up to 5-­‐10 sec forward planning with the ✴extensive amount of sensors is ✓less needed for reliable automa;on
✓no legacy vehicle problem
exchange of maneuver plans
sensors are needed for reliable automa;on, 5.9 GHz broadcas;ng and sensors are complementary
✓Oncoming vehicles can be detected even when not visible
The mission of AutoNet2030 is to prove and demonstrate the benefits of coopera-ve ITS automa-on
✓Direct V2I coordina;on with intersec;on controllers is feasible
✴legacy vehicle problem, concerning non-­‐
coopera;ve vehicles

AutoNet2030 mission statement
Specific project objec<ves:
• Standardized use of 5.9 GHz V2V communica;ons in service of automated driving
• A path for cost-­‐op;mized automated driving technology, making it more widely deployable
• Demonstra;on of inherently safe coopera;ve maneuvering control algorithms
Rather than designing a single ‘maneuvering algorithm’, the approach is to develop a number of algorithms for specific traffic scenarios. There is a dynamic transiPon among the vehicle states.

Proposed CAM extensions -­‐ 1/3
On of the most important standardizaPon request is the extension of the periodic CooperaPve Awareness Messaging (CAM) for automated driving support. The AutoNet2030-­‐AdaptIVe-­‐iGame projects are preparing a joint CAM extension proposal. The currently considered addiPonal fields are as follows:

Proposed CAM extensions -­‐ 2/3

Proposed CAM extensions -­‐ 3/3
In AutoNet2030, we consider traffic situaPons in which the awareness is paramount and we require that CAMs are transmiged with 10Hz in several situaPons e.g. when driving in a platoon or convoy. For this reason, we introduce addiPonal generaPon rules that transmit CAMs a high frequency in such situaPons also exploiPng more than one transmission channel to divide the load.
The generaPon rules of the extended CAM are proposed per operaPon mode: !
Normal Mode: the triggering condiPons and generaPon rules in ETSI EN 302 637-­‐2 apply. The generated CAMs are transmiged over the Control Channel (CCH).
!
High Awareness Mode: 10 Hz CAM generaPon. The generated CAMs are transmiged over CCH according to usual rate rules, addiPonal CAMs are transmiged over the Service Channel 6 (SCH6).

Should some maneuvering algorithms be also standardized?
Some maneuvering algorithms, such as CooperaPve-­‐ACC, use the dynamics of their neighbors as input parameters. The following formula shows an example of Laplacian control approach to mulP-­‐lane CooperaPve-­‐ACC (m,n are neighbor indices, x,y are longitudinal and lateral coordinates):
This kind of approach reliably converges to a stable formaPon if the control parameters of above equaPon are the same for all vehicles. !
Should ETSI ITS scope include also the standardiza;on of such maneuvering control algorithms?

ITS G5 channel usage for vehicle automaHon support
Vehicle automaPon use cases require low-­‐latency communicaPon and frequent broadcasPng of vehicle data. AutoNet2030 overcomes CAM frequency limitaPon (as set by congesPon control) by sending addi<onal CAM messages on a Service Channel. The policy is being considered also by AdapPve project.
ETSI SCH6 (ITS-­‐G5D, for future ITS) could be the candidate. However, current standard ETSI EN 302 663 sets too low power limit.
AutoNet2030 and Adap,ve are evalua,ng together another Service Channel for demonstra,on purposes, ad interim (possibly SCH1). 27/3/2015
