Transport systems can be improved in terms of efficiency and safety by cooperative behaviour among different traffic participants (Adaptive. 2015). For L3 functions, the driver needs to be ready to take over control of the vehicle and so it is essential that it is defined how the cooperation between the involved agents (vehicle ADF, user, infrastructure and other road users) is established, considering that the driver must understand when s/he is in control of the vehicle and when a transfer of control occurs. This should be defined in the design phase of the development process. This cooperation can happen at either strategical level (e.g. navigation), tactical level (e.g. guidance) and / or operational level (e.g. control) (Flemisch et al. 2016).
Additionally, it is necessary to identify the performance boundaries between the ADF and the user. Shared control should communicate the proximity to task boundaries, environmental constraints or function limits to facilitate a need for adaptation in control strategy or adaptation in the cooperation balance (Abbink et al. 2018).
Since this question shall be addressed at the design phase, it is also relevant to define a concept to validate the defined performance criteria, although the validation concept will be implemented in a later phase.
Main Question
Are cooperative systems between ADF and the driver considered? (The driver may be inside or outside the vehicle.)
Sub-Questions
- Is the specific performance of the ADF (including performance boundaries) clearly defined for the user?
- Is a concept developed to validate each of the performance criteria that have been set?
