Autonomous Vehicle Control Systems- State of the Art of Decision-Making
and Maneuver execution
Abstract
As self-driving cars perform more tasks, new challenges arise. One of
these challenging tasks is autonomous driving decision-making due to the
uncertainty of the vehicle’s complex environment. This paper provides an
overview of decision-making technology and trajectory control for
autonomous vehicles. The main common goal in decision-making is to
consider uncertainties, unpredictable situations, and driving tasks to
propose a global and robust solution adapted to each situation. The main
concern is safety. Decision-making falls into three categories. The
first is the traditional approach, which often consists of building a
rule system and deriving optimal operations. The advantages of such an
approach are well known for being easy to understand and applicable to
small problems. The second category of decision-making is based on a
probabilistic process and, due to its efficiency, has several
applications in this area. The third category is learning-based
approaches. Once a decision has been made, manipulate the steering angle
or accelerator/brake pedals to perform the appropriate action. Two
approaches are existing to designing autonomous driving controllers.
Either based on imitating human drivers that includes approaches based
on the use of driver models such as AI, or the use of approach-based
models
