Controllability of vehicle from User’s Perspective

The design phase should consider the limitations and perception of the driver. The AV’s behaviour therefore should be designed in such a way that it is controllable/foreseeable for this user. (Bolovinou et al. 2019)

Main Question:

Is the vehicle controllable (in the sense defined above) in the event of a system malfunction or limit by overriding or switching off the function?

Note: driver’s actions are always referred to the primary commands (breaking and accelerator pedals, steering wheel).

Sub-Questions:

  1. Is it possible for the driver to deactivate or take back control of an ADF at any time?
  2. Is it ensured that driver actions to override the function or take back manual control are intuitive?
  3. Is the possibility of function activation or deactivation in situations, in which this would lead to potentially hazardous driving conditions, considered in the concept selection?
