Swept Steer
A Swept steer event simulates a ramped steer input into a vehicle driving at a steady speed.
The event is typically used to predict the steady state dynamic response of the vehicle. Input is steering wheel angle. Standard vehicle output requests are included in the event. The Altair Driver maintains constant speed and steers the vehicle. A plot template is available to plot the results.
Figure 1.
The parameters available in the Swept Steer event are detailed in the following
table:
| Parameter | Description |
|---|---|
| Initial Steer | An initial steer angle of the vehicle. This angle should be a small angle that is used to drive the vehicle in a straight line. |
| Steer ramp rate | The rate the steering is increased in degrees/sec at the Steer delay time. |
| Maximum steer | The maximum steering angle in degrees |
| Velocity | Velocity of the vehicle during the event in meters/sec. |
| End time | Absolute end time of the event, in seconds. |
| Print interval | Data is output to the plot files and graphics file at this time interval (seconds). |
