ABSTRACT

ABSTRACT: Paper presents an innovative method for finding the best setup of: race driver actions, vehicle motion trajectory, and vehicle chassis parameters for a closed-loop maneuver. Formulated “miMa” simulation model of driver-vehicle-road system with 26 generalized coordinates and more than 400 parameters is implemented for optimization with genetic algorithms. Numerical example considers Ford Focus ST170 (FWD) prepared for a track racing, which is negotiating a selected track part with RH corner. The combined optimization includes 28 decision variables. Two criteria, i.e. section time and exit velocity, are defined as optimization goals. Different strategies for improving performance of FWD car are found by using optimization.
