Below are some recommendations for using Altair Driver:
- Symptom
- The driver simulation fails immediately.
- Remedy
- Verify that the vehicle position is consistent with the specified path. The path
points need to be close to the vehicle at design position.
- Symptom
- The driver seems to turn the steering wheel angle counter-intuitively and it does
not follow the prescribed path. The simulation fails.
- Remedy
- This is probably caused by positive feedback. This can be fixed by reversing the
sign of the steering wheel angle signal or the steering rack ratio.
- Symptom
- The driver follows the path, but it is too sluggish. The simulation fails.
- Remedy
- This could be caused by a preview time that is too long for the maneuver and the
vehicle speed, especially if the steering signal seems to start responding too soon.
- Symptom
- The driver follows the path, but its actions are too sudden and the steering wheel
angle signal is too jumpy.
- Remedy
- This could be caused by a preview time too short for the maneuver and the vehicle
speed, especially if the steering signal seems to start responding too late.
