Timeline
History
Cooperative driving has its roots in the Prometheus Project!
First work 1988-1989 in the subprojects PRO-COM, PRO-NET and in Copdrive
CED4
Technology: Radio location/orientation and communication
Photo taken at the Munich Test Track in preparation
for the first board meeting
CED4 presentation: radio location and communication.
Exchange of the intention of maneuvers and exchange
of actual maneuvers. Display of the state for external
observers through 2 lamps on the roof. The vehicles
were driven by the drivers, no GPS!
During the course of the project, the focus shifted towards
registration and communication of warning messages.
The Mercedes-Benz demo vehicle!
However, technology in location and communication has changed dramatically since then!

Cooperative Systems
Advance Information:
Sensing and communicating to get information ahead of time
Drivers / cars get to know everything going on around them,
even things they cannot sense themselves, and can condition
themselves to react more quickly and in a better way.
Harmonious Driving:
Acting coordinated to avoid detrimental behavior
Drivers / cars adapt their driving for higher traffic efficiency,
better fuel economy, or avoidance of safety-critical situations.
Cooperative Maneuvering:
Bringing it all together
Drivers / cars negotiate their driving maneuvers
for higher road safety and road efficiency. Traffic lights
communicate their status and phases.
