AutoTrac Universal Addendum - StellarSupport - John Deere

SETUP
Acquire Sensitivity Determines how aggressively the
vehicle acquires the track. Higher gains will result in more
aggressive steering while acquiring the track. Lower gains
will give smoother entry into the next track. Setting
sensitivity too high may cause vehicle instability; setting
too low will delay acquisition. This setting affects
performance while acquiring the track only
Line Sensitivity – Tracking Determines how aggressively
ATU responds to tracking errors while the vehicle is on
the track. Tracking error is the distance between the
vehicle’s location and the desired track. Setting this
number higher will cause ATU to respond more
aggressively to match the vehicle location to the desired
track. Higher numbers will result in more aggressive wheel
motion. Lower gains may result in reduced accuracy. This
setting affects performance while on track only.
Line Sensitivity – Heading Determines how aggressively
ATU responds to heading errors while the vehicle is on
the track. Heading error is the difference between the
vehicle’s actual direction and the track direction. Setting
this number higher will cause ATU to respond more
aggressively to match the actual vehicle direction and
track direction. Higher numbers will result in more
aggressive wheel motion. Lower numbers may result in
reduced accuracy. This setting affects performance while
on track only.
Curve Sensitivity Determines how aggressively ATU
responds to a curve in the track. If the tractor is turning
inside of the curve, this number should be set lower. If the
tractor is turning outside of the curve, this number should
be set higher. This setting affects performance in curve
track only.
