To solve poor self-adaptive of common fuzzy logic strategy adopted by the active suspension of vehicle,the paper puts forward the fuzzy logic strategy with adaptive control characteristics,which use fuzzy control rule of analytical formula. The correction of error and error rate which is two input of fuzzy controller in different state is optimized by the new improved genetic algorithm,in that the optimal fuzzy control rule of the controller is found. The active suspension system with improved fuzzy logic controller was simulated by Matlab/Simulink. The simulation results demonstrate that the suspension with the fuzzy logic controller can effectively improve vehicle’s riding performances and handling performance compared with conventional passive suspension and the active suspension with common fuzzy logic controller. The controller by optimized has strong robustness and stability.
