Abstract:In order to improve the fidelity of the ADSL driving simulator,the new steering model,wheel model and braking model are proposed.The force-input steering model considers the system elasticity.The wheel model considers the elasticity of pneumatic tire,dynamics of contact patch and contact model.The break model uses stick-slip friction model.The new model can truly calculate the correspondence of left and right steering wheels and the tire force,and simulate the stand-still,braking and zero speed.By comparing the handling results of new model,2000 model and the field test,the correctness of the model is validated.It is concluded that the precision of the new model is high.
