Levels of automation* & functions
AdaptIVe considers velocities up to 130 km/h on motorways and similar roads.
Enter and exit highway
Vehicle drives on entrance or exit ramps and filters-in / filters-out.
Cooperative response to emergency vehicles on duty
Vehicle responses to a specific Vehicle-2-Vehicle communication (V2V) message from an emergency vehicle. It changes lane to support the passing of the emergency vehicle. The driver supervises the system.
Speed and time-gap adaptation at motorway entrance ramp
The vehicle adapts speed and time gap at a motorway entrance ramp if another vehicle wants to filter-in.
Lane change or filter-in manoeuvres
The vehicle drives towards a highway entrance ramp. The function finds or creates a gap via V2V communication in the moving traffic. If another vehicle is attempting to merge in from a highway entrance ramp in front of the vehicle, the function enables the other vehicle to merge by either reducing the speed to create a gap in front of the vehicle or by completing a lane change, if possible.
Danger spot intervention
The function extends the knowledge of the system about situations which are not in the vehicle’s field of view.
Predictive automated driving, reducing fuel consumption and CO2 emissions
The system automatically adapts the speed due to oncoming events such as e.g. speed limit signs.
Following lane and vehicle, lane change and overtaking manoeuvre, stop & go
Driving in a traffic jam – stop & go – is a special case of following a lead vehicle. The purpose of the lane change and passing function is to change the lane if necessary due to e.g. a slower vehicle ahead or infrastructural reasons like exit lanes.
If the driver does not react to a take-over request, the system will perform a minimum risk manoeuvre. On a motorway, the vehicle will come to a standstill in the breakdown lane. If no breakdown lane is available, the vehicle will slowly come to a standstill in the right-most lane. The manoeuvre will be transparently indicated to other traffic participants making it predictable for other road users.
The following video presents the "BMW Nothalteassistent", an innovation for safe stop by BMW Group (in German only).
- AdaptIVe demonstrates and evaluates automation-stage transitions from “partly automated” to “driver only” or “highly automated” to “driver only” in driver take-over situations.
- Fault-tolerant and resilient system architecture for highly automated driving functions will be developed and tested.
- Extensions to the existing V2V communication protocols based on ITS G5 will be specified, implemented and tested to enable dialog and negotiations among involved vehicles before and during lane change or filter-in manoeuvres.
- New application requirements will be identified along the way. Additionally, a new set of messages and mechanisms will be defined ensuring a robust and fault-tolerant cooperative system.
- The protocol extension will be used for the discussion with standardisation organizations.
