| Abstract | ||
| A lateral vehicle dynamic system response is investigated using two degrees of freedom Bicycle Model for the Vehicle besides Linear Model, Linear saturation model and Magic Formula for the tires. The Bicycle model is represented by the yaw rate (vehicle rotation around it’s z-axis) and lateral acceleration. The Tires models are represented by the lateral force. Five Different Tires characteristics are demonstrated by the three Tire Models using five altered wheel steering and longitudinal velocity inputs (step=30o & u=70mph, step=45o&u=70mph, sine with 0.4Hz, Magnitude=15o & u=70mph, sine with 0.4Hz, Magnitude=15o & u=55mph, sine with 0.4Hz, Magnitude=15o & u=35mph). Time Response, Frequency Response and root locus are performed to analysis the tire characteristic effects on the vehicle yaw rate. | ||
