Driver Controls Path Follower Method¶

The Method tab of the HVE Driver (Path Follower) page selects how the path correction is accomplished. Two methods are defined:

Variable Steering¶

The path correction is accomplished by means of a steering correction. The user supplies the following data:

Initial Angle (deg) — Initial steering wheel angle at driver start time.
Max Velocity (deg/sec) — Limit on steering wheel velocity (how fast the driver can turn the wheel).
Correction Factor (deg/sec) — Amount of steering correction per unit of path error (steering correction rate).
Correction Damp (deg) — Steering correction damping, used to limit steering activity.

The path correction is accomplished by means of a torque application at the steering wheel. In this case the user supplies the following data:

Initial Steering Torque (in-lb) — Initial steering wheel torque at driver start time.
Max Steering Torque (in-lb) — Limit on steering wheel torque.
Torque Correction Factor (in-lb/in) — Amount of steering torque correction per unit of path error.
Torque Damping (in-lb-sec/in) — Torque correction damping, used to limit steering activity.

Note: The Variable Torque option is currently disabled in the user interface; Variable Steering is the available path follower method.
