Abstract: The grey relationship between the objective and subjective evaluation of motor vehicle maneuverability and stability is studied based on genetic algorithms and grey relation analysis. The research result of the simulation experiment states that the evaluation formula given by genetic algorithms and grey relation analysis can be used in the optimum design of vehicle parameters that make vehicle maneuverability and stability to be more suitable for human’s feeling. It also states that the key point to which the subjective evaluation driver pays attention during the evaluation process can be discovered by this simulation.
