Autopilot system calibration 6 Vehicles
Calibration Explanation
Automated steering deadzone
calibration, 156
Note – Only for front wheel
steered and articulated
vehicles.
For learning the vehicle’s steering dead zones. Determines the
minimum valve command required for steering movement.
Proportional steering gain, 160
Sets the proportional gain to control steering overshoot and
responsiveness.
Steering sensor calibration, 154 Converts the voltage output of the steering angle sensor into
an equivalent steering angle measurement.
Line acquisition, 165
Controls how fast the guidance system attempts to steer the
vehicle onto the current guidance line (50% - 150%).
Engage aggressiveness, 166
How aggressively the vehicle initially engages on the guidance
line (50% - 150%).
Roll correction calibration, 162
Compensates for minor variations in the placement of the
navigation controller and GNSS antenna.

Manual override sensitivity calibration
WARNING – Incorrect adjustment of Manual Override Sensitivity could cause this critical safety feature to fail,
resulting in personal injury or damage to the vehicle. Do not to choose a setting that is either too sensitive or not
sensitive enough. It is vital to avoid setting the sensitivity so low that the system will not detect any steering
wheel motion.
Note – This control is for platforms that use a pressure transducer or encoder for manual override.
The software detects whether or not the system uses this type of sensor.
One way to disengage the Autopilot system is to turn the steering wheel or manually override
automatic steering. When you turn the steering wheel, there is a voltage spike that then tapers off.
This spike and decline occurs at different levels for different models of tractor.
Manual Override Sensitivity sets the level that the voltage must reach before the guidance system
disengages. The voltage must also drop below that level before automated steering can be engaged
again.
