MEDIATOR behind the scenes: monitoring the driver

21 December 2021

MEDIATOR has published an article in which they present their new driver state component with key concepts such as of fatigue, distraction, and comfort. The system can arbitrate between a human driver and the vehicle’s automation function based on who is fittest to drive, in real-time.

The driver state component consists of four factors that together determine the overall value for the current and near future driver state: the Integrated Driver State Fitness Value (IDSFV).

The first factor concerns the driver’s fitness and consists of two elements. The first is the time to driver fitness (TTDF) and is the time until a driver is able again to safely perform the manual driving task. The second element of the driver’s fitness component is the time to driver unfitness (TTDU) and concerns the time until the driver is no longer able to safely perform the task at hand.

The driver state component determines the TTDF and TTDU by looking at two aspects of the driver, namely, fatigue and distraction. Driver distraction is determined by in-vehicle cameras that observe a driver’s eyes and body to see if the driver is engaged in non-driving tasks. The determination of driver fatigue is based on a combination of camera data and physiological measurements.

The final element of the driver state component is driver comfort and is also determined by camera data through facial expressions.
