In the calibration parameters, the operator can view the left/right limit and center line
wheel of the guide wheel, the side inclination and path deviation of vehicle, vehicle
deviation and etc. Each calibration value should be in the normal range to show that
the calibration work is correctly completed.
Values of left/right limits and center line wheel of the guide wheel increase or
decrease sequentially with a difference of no less than 20°between two adjacent
values
Values of path angle, side inclination and pitch angle are no more than 5°
The deviation of farming vehicle is no more than 10cm
If the above requirements are not satisfied, the corresponding item should be
recalibrated.

Auto Driving Test in Farmland
When all the calibration items of AG960 are completed, an auto driving test should be
performed in the farmland to ensure the product conditions after commissioning.
Power off and restart the equipment which has been calibrated. Enter the user
interface to complete the auto driving test in farmland. The duration should be at least
20min, and the distance should be at least 2000m for the auto driving test. The test is
done as follows.
Drive in auto driving mode at different speed, such as 1m/s, 2m/s, 3m/s and etc.,
and the vehicle should be able to run stably at all speeds. The vehicle head should
not sway during the driving process and the driver does not feel discomfort.
The instrument indicates a lateral deviation of no more than 2cm in both left and
right side during the driving process. Observe the traces of wheels with eyes,
which should be very straight without any bend apparent to the naked eyes.
Track Line AB from an initial position of 0.5m lateral deviation, 1m lateral
deviation, 0
°
path deviation and 30
°
path deviation. The vehicle can track Line
AB within 5m at different speed and the vehicle passes Line AB once at the
utmost during the tracking process. The following cases will not happen, i.e. the
vehicle repeatedly tracks and leaves Line AB or even fails to track the line.
The equipment can only be delivered to the user when the above mentioned
requirements are satisfied.
