Abstract： Based on the characteristics of pure electric bus with heavy battery and great transferring axle load, the non-linear dynamic analytical model was established with considerations of driving velocity and load change under curve driving condition. The fitness function was constructed by computer simulation technology and experimentation design method. Genetic algorithm was proposed to realize the parameter identification of the non-linear cubic tire model. The simulation results show that the higher the initial velocity and deceleration in cornering with braking are, the transient response becomes more sensitive with worse handling and stability. With the increase of load, the steady value of yaw rate gain decreases with worse steering response and sensitivity, while the steady value of roll angle is increased with increased rollover possibility. The simulation results are consistent with the real vehicle test data, which illuminates the feasibility of parameter identification and the accuracy of the model.
