The HADRIAN f-HMI key elements

 

The HADRIAN f-HMI will combine multiple technological and HSI innovations.

The HADRIAN fluid tutoring system is context sensitive training method for driver to develop a more complete mental model of the automated system and increase its transparency and therefore acceptance and calibrated trust

The HADRIAN Fit2Drive system is intended to detect hazardous driver states such as distraction, fatigue, or inattention and to anticipate certain unsafe intentions before the vehicle could get into an inextricable situation that requires switching to a lower automation level or even force a sudden take-over by the human driver.

The HADRIAN haptic steering wheel feedback algorithm allows active and passive signaling to the driver during shared (human – automation) collaborative driving as well as to help transition back to manual driving.

The HADRIAN Head-Up Display will implement two different principles to facilitate fluid human-vehicle interactions. It will highlight critical information on a window-like display during transition situations or provide explanatory information for specific vehicle control interventions that are intended to increase the safety of certain driving situations.

 

Innovative Safety Assessment Method

To assess the safety and impact of HADRIAN f-HMI interactions during transitions between SAE automation levels, e.g. from SAE level 4 to level 3 or 2) as well for novel automation concepts, behavioral data from studies with human participants are used to compare performance under baseline and f-HMI conditions. The focus is on comparing the safety of baseline HMI operations with the advanced f-HMI operations.

 

Impact Assessment Method

The impact assessment will investigate whether the HADRIAN f-HMI solutions are trustworthy and acceptable.

Objectives

The HADRIAN Project has following objectives:

  1. Demonstrate how the characterization of novel driver roles based on fluid interaction design leads to 90% safe AD level transitions for a set of HADRIAN applications cases e.g. shared and individual mobility and professional freight transport.
  2. Demonstrate safe AD level transitions for a set of HADRIAN application cases using fluid interaction designs that at least 80% of users find acceptable
  3. Demonstrate that least 80% of users achieve calibrated trust in AD and AD level transitions over time when using fluid interaction designs for a set of HADRIAN applications cases.
  4. Develop innovative technology bricks regarding fluid HMI, sensor data-fusion, driver-models, and decision logic
  5. Develop Human-Systems, Integration guidelines & recommendations around a human-centred methodology to create safe, acceptable as well as usable, and trustworthy AD technologies & AD level transitions. These recommendations and guidelines are intended for infrastructure providers, road operators, and OEM’s

 

Experimental Studies

The HADRIAN experimental studies examine specific aspects of the f-HMI key elements that are particularly relevant for the understanding of the new driver role in highly automated vehicles and the associated necessary technical developments for the f-HMI. Different study designs and methods are used.

The HADRIAN Demonstrators

The Hadrian f-HMI Demonstrators will be built for driving simulation studies as well as for at least two field-tests. In the field-tests various key-elements of the fluid interface will be demonstrated in real passenger vehicles and a freight vehicle under real-world operational conditions, primarily to determine functionality and acceptability for the fluid concept. Demo Vehicle 1 will be a large passenger vehicle (M-class), Demo Vehicle 2 a small passenger vehicle (light urban vehicle; L-class), an additional Demo Vehicle 3 may consist of an N-class vehicle. While not all features will be evaluated in the field-tests, critical key-elements will be selected so that an overall assessment can be completed. The field tests will be conducted on a test track and limited operational conditions may be demonstrated on real roads.
