The accumulation within the cars cockpit of assistance systems interacting with the driver via various modalities (visual, manual, tactile, sound, etc.) jointly with the increase in the complexity of these systems (ranging from information to automatic driving) raises new problems of cooperation between the driver and the vehicle.
Ensuring good safety conditions needs to focus particularly on the compatibility of the whole of these systems with the vehicle guiding task, especially in terms of “comprehension of what the system does”, of “conscience of the activated modes” and of “capacity of attention and treatment” (situation awareness, workload) which they are likely to require.
The CoCoVeA project is managed by consortium made of car manufactures, research centres and universities that aims to:
- develop a cooperative architecture between driver and assistance system for automatic driving (vehicle control sharing through haptics);
- develop a prototype for the control and coordination of the systems embedded in the cockpit;
- integrate these systems on several demonstrators in both driving simulator and real vehicles;
- validate through an experiment the developed systems;
- produce recommendations for the manufacturers and equipment suppliers.
The work carried out in the CoCoVeA project allowed:
- to define a multilevel cooperation architecture allowing interactions between the driver and the autonomous vehicle;
- to define the driver's monitoring needs both during the manual driving and delegated driving phases, in order to ensure the safety of the vehicle;
- to define the mechanisms of transitions between driving modes and the conditions associated with these transitions, in order to guarantee safety;
- to prototype all of these works in the form of an integrated system on a dynamic interactive driving simulator;
- to prototype some of this work on a real vehicle;
- to evaluate the prototype made on the driving simulator in the context of an experiment involving a representative panel of drivers.
