Multiobjective Discovery of Driving Strategies

Keywords

multiobjective optimization, evolutionary algorithms, driving strategies, traveling time, fuel consumption

Description of the Problem

  • Goal: reduce the environment pollution
  • Pollution reduction proportional to reduced fuel consumption
  • When the fuel consumption is reduced, the traveling time increases
  • Therefore, both objectives need to be taken into account simultaneously
  • We propose a multiobjective optimization algorithm, called MODS, that
    • searches for driving strategies
    • uses a black-box vehicle model
    • minimizes the traveling time and fuel consumption
    • produces a set of incomparable driving strategies, i.e., no strategy is better in both objectives than any other strategy
  • Advantages for users:
    • a different strategy can be selected when the requirements change without restarting the algorithm
    • no time or fuel constraints have to be specified
    • no preference among objectives has to be specified

Purpose of the Dissertation

  • Enhance existing methodology for discovering driving strategies, i.e., weighted-sum approaches, by a multiobjective approach
  • Produce better results than existing weighted-sum approaches

Hypothesis

Multiobjective approach is capable of finding better driving strategies than weighted-sum approaches
