Human-Machine Arbitration in Hybrid Driving Systems

A hybrid driving system (ADS), as depicted in the diagram, includes several functional steps: 1) environment detection and perception, 2) mapping, 3) high-level strategic control, 3) mid-level tactical control, and 4) low-level motion actuation. When drivers are involved in intervening or taking over the vehicle, their interaction with the automated driving systems becomes critical. Human-machine arbitration is needed for decision-making tasks such as local trajectory planning and driving behaviors, in order to generate a suitable output at the tactical level.

About the Project

At a glance

A number of companies have announced that by 2020 they will have highly or fully automated vehicles ready for the market. While selective companies may indeed offer driver-less cars (Level 5 per SAE J3016), most market-ready products in the upcoming decade will likely be categorized as partially automated cars (Levels 2-4, per SAE J3016). We will refer to these automated systems, in which machine and driver share driving tasks, as hybrid driving systems (HDS).

The implementation of HDS faces equally challenging if not greater, albeit somewhat different, problems when compared to fully automated systems. The challenges are particularly noticeable when a human operator is involved in the loop of decision-making and during transition between automated and manual modes. For example, serious risks may arise when control is yielded back to a human under various unknowns and uncertainties. Some concerns have been raised as to whether HDS can be safely deployed in the near future.  For hybrid driving systems to function properly, human-machine inputs need to be arbitrated to achieve safe and effective interaction with the surrounding environment.  The primary objective of this project is to explore the potential of applying deep-learning methodologies to perform human-machine arbitration, with an emphasis on the decision-making and control strategies for HDS.
