Abstract

To improve the aerodynamic characteristics of the rear wing and enhance the handling stability of the racing car, based on the orthogonal experimental design and iSIGHT platform, the multi-objective optimisation of the structural parameters of the spatial layout of the rear wing was carried out to determine the optimal combination of the angle of attack between the rear wings and the clearance between adjacent wings. A hybrid fuzzy PID variable rear wing control system was developed to suppress vehicle roll by real-time control of the flap angle of attack. The co-simulation results show that as the road adhesion coefficient decreases, the variable rear wing system improves the handling stability of the car more and more and the suppression of vehicle roll gradually increases, with the improved handling stability on slippery roads, the car's cornering performance and driving safety are enhanced.
