Abstract:

This paper presents the design of a discrete decision making algorithm for vehicles with advanced driver-assistance and automated features. We model the system as a hybrid automaton, where transitions between discrete modes in the automaton correspond to driving mode decisions, and develop a method to determine the timing of mode transitions based on backward and forward reachable sets. The algorithm can be used either as a stand-alone component or as a method to guide an underlying motion planner to safe reference trajectories. Under certain assumptions, the algorithm guarantees safety and liveness, which can be validated through computer simulations on a city driving scenario that requires going through multiple discrete modes and includes several surrounding moving obstacles.

      • MERL researcher Stefano Di Cairano and Prof. Ilya Kolmanovsky, Dept. Aerospace Engineering, the University of Michigan, were invited to teach a class on "Predictive and Optimization Based Control for Automotive and Aerospace Application" at the 2019 International Graduate School in Control, of the European Embedded Control Institute (EECI). Every year EECI invites world renown experts to teach 21-hours class modules, mostly for PhD students but also for professionals, on selected control subjects. Stefano and Ilya's class was attended by 30 "students" from both academia and industry, from all around the world, interested in automotive and aerospace control. The module described the fundamentals of modeling and control design in automotive and aerospace through lectures, real world examples and exercises, and placed particular emphasis on techniques such as MPC, reference governors, and optimal control.
