Abstract: A characteristic-based real-time dynamic steering system model was built. The model is based on the steering angle ratio, torque ratio and softness of Ackermann mechanism. It does not need a lot of parameters of hardpoint positions and is suitable for building model at the automotive predevelopment stage. The dynamic degrees of freedom (DOFs) of the key parts of the steering system were taken into consideration in the model, which reflect their dynamic behaviors. The steering model was embed in the simulation code of a 14 DOFs vehicle model, and an A-class vehicle handling performance simulation was carried out. The simulation results were compared with field test results, which verified the effectiveness of the developed model.

Key words: vehicle engineering, steer system model, steered wheel rotation about kingpin, dry friction, vehicle model
