An optimized fuzzy logic control(FLC)strategy for modular all-wheel drive vehicles is proposed for the power configu-ration of electric vehicles and hybrid electric vehicles.In the dynamic model of a vehicle,magic formulas are used to define tire slip associated with load transfer in curves or driving/interruptions.The torque of the motor in the wheel is adjusted through a con-troller to achieve trajectory correction of the vehicle.A multi-objective optimization method based on genetic algorithm is proposed to study the control effects of vehicle mass,center of gravity position,wheelbase,and wheelbase on vehicle robustness.A compari-son with traditional PID control methods shows that the proposed FLC can effectively control vehicle trajectory.Finally,the effec-tiveness of the proposed FLC control strategy is verified through a semi physical experiment.
