To address the issue of the unsuitability of the original suspension parameters after upgrading a central motor electric vehicle to a In Wheel motor car, A half-car passive suspension model is established in MATLAB/Simulink to analyze the problem. The spring stiffness and damping coefficients of the front and rear suspensions are taken as independent variables, while the root mean square values of the vehicle’s center of gravity acceleration, pitch angle acceleration, suspension deflection, and tire load are considered as optimization objectives. The grey wolf optimization algorithm is employed to search for the optimal stiffness and damping parameters. The simulation results show that after optimization, the handling stability of the suspension remains within a reasonable range, while the comfort level is improved by 12.73%.
