Calibrations: Tilt, Turn Angle, Advanced Turn Angle

To ensure precise navigation with PowerSteer, you must calibrate your vehicle with the PowerSteer profile.

• Tilt Calibration (required) ensures the accuracy of the steering system by compensating for any inclination of the controller due to uneven terrain. Without proper calibration, the system may misinterpret the vehicle’s orientation, leading to inaccurate steering adjustments.

• Angle Calibration (required) ensures that the steering controller accurately interprets the wheel angle, preventing incorrect steering commands and improving overall navigation precision. Without proper calibration, the system may miscalculate turning angles, leading to steering inaccuracies.

• Advanced angle Calibration (optional). To achieve a more accurate Turn Angle Ratio for your vehicle, we recommend performing this calibration. It helps with:

  • • Reducing long entry times when aligning with the guidance line.
    • Minimizing cross-track errors that cause drifting to one side.
    • Correcting steering column asymmetry for improved accuracy.

  This calibration enhances steering precision and overall system performance.

Tilt Calibration

Tilt calibration ensures accurate steering by compensating for any tilt in the controller. To perform the calibration, you will need approximately two minutes and a flat surface. Follow these steps:

1. Mark the initial position of the wheels.
2. Park the tractor on a flat surface and remain stationary for 15 seconds to allow the system to record the tilt data.
3. Turn the tractor 180 degrees.
4. Stop on the same flat surface and remain stationary for another 15 seconds to complete the calibration.

This process helps the system correct any tilt-related errors, improving steering accuracy on uneven terrain.

Turn Angle Calibration

Turn angle calibration ensures accurate steering response by correctly mapping the full range of wheel movement. The process takes approximately two minutes and requires a flat surface. Follow these steps:

1. Park the tractor on a flat surface.
2. Fully turn the steering wheel to the left and tap "OK" to confirm.
3. Fully turn the steering wheel to the right and tap "OK" to complete the calibration.

This calibration allows the system to precisely detect steering angles, improving navigation accuracy and overall performance.

Advanced Turn Angle Calibration

Advanced Turn Angle Calibration is available from firmware version 2.3.6.

For Advanced Turn Angle Calibration, both Tilt Calibration and Turn Angle Calibration must be completed first.

To perform this calibration, you will need 5 to 15 minutes and an open space (the required area is calculated based on the wheelbase). The recommended speed is 3–5 km/h.

During calibration, the system will automatically steer the tractor in a figure-eight pattern.

Calibration Completion Criteria:

• 3 successful right turns completed.
• 3 successful left turns completed.

• 

Do not switch to manual control.
