About

In the context of ever-increasing automation in surface vehicles, automation impact on drivers will be investigated through three complementary research axes undertaken under simulated driving:

Axe 1 (Cognitive ergonomics), how automation is impacting driving behaviors and visual explorations? Axe 2 (Experimental psychology), how automation is impacting drivers' mental representations of their own driving abilities? Axe 3 (Neuroimaging), how automation is modifying the car driving neural network? And what are drivers' mental representations neural bases? The project tackle both applied and basic research issues using an original experimental neuro ergonomics approach. AUTODRIVE will bring original data on human-machine cooperation, mental representations, cognitive control and brain processes depending on the characteristics of the automation used over a significant period of time (six weeks) on a large sample (N=120) of experienced and inexperienced drivers.

120 participants in 6 patient groups

UnAssisted (UA)

Experimental group

Description:

This term refers to driving a vehicle manually without any vehicle automation technology. It will serve as a baseline concerning behaviors, representations and neural results associated with unassisted automobile driving.

Treatment:

Device: Level of vehicle automation

Assisted (A)

Experimental group

Description:

This term refers to driving with warning technology which upon activation sounds an a warning when the vehicle is too close to the edge of the road (off-road warning , Navarro, Mars, \& Hoc, 2007; Suzuki \& Jansson, 2003) or too close to the vehicle in front of it (anti-collision warning; Lee, McGehee, Brown, \& Reyes, 2002).

Treatment:

Device: Level of vehicle automation

Shared Control (SC)

Experimental group

Description:

This term refers to shared tactical control between the driver and the automated assistive technology, both working simultaneously on the physical trajectory of the vehicle, laterally (Griffiths \& Gillespie, 2005; Mulder, Abbink, \& Boer, 2012) as well as longitudinal (Adell, Várhelyi, \& Hjälmdahl, 2008).

Treatment:

Device: Level of vehicle automation

Partly Autonomous (PA)

Experimental group

Description:

This term refers to a situation where the lateral and longitudinal control of the driving are delegated to the automated assistive technology. It consists of a level of automatisation that today is possible to put into application and which often is referred to by the name "Highly Automated Driving" (Navarro, 2018). In this case, the driver is no longer the one who physically ensures the lateral and longitudinal control of the vehicle, but instead supervises the actions of the automated assistive technology.

Treatment:

Device: Level of vehicle automation

Fully Autonomous (FA)

Experimental group

Description:

This term refers to a completely automated driving experience. The on-board technologies take over all the driving tasks for any driving situation.

Treatment:

Device: Level of vehicle automation

Any Automation (AA)

Experimental group

Description:

This term refers to a situation where the drivers can choose the automation device of their choice among the five types presented above and can change it whenever they think it is good to do so.

Treatment:

Device: Level of vehicle automation
