6 Vehicles Autopilot system calibration
Message:Error - .... Explanation
Software Problem Detected The software was unable to complete the calibration due to
insufficient movement of the vehicle. If the problem persists, contact
Technical Support.
Steering Close To End Stops Before the calibration cycle could be completed, the measured
steering angle approached the end stops. Retry, and if the problem
persists, instead of centering the steering at the start of each cycle,
try turning the steering in the opposite direction to that which is
being tested so that the calibration procedure has a greater range to
test over.
Unable To Determine DZ:
Try Again
A problem occurred when trying to compute dead zone. Retry. If the
problem persists, contact Technical Support.
Valve Connectors Could Be
Swapped
The calibration test sensed the steering turning in the opposite
direction to what was expected. Retry. If the problem persists, either
the valve connectors have been accidentally swapped or the
steering sensor calibration was performed incorrectly.
Vehicle Moving Too Slow The vehicle was moving too slowly for the calibration cycle to
successfully finish. Make sure the vehicle is moving at least 0.8 kph
(0.5 mph) during each calibration cycle.
Proportional steering gain
Note – Adjust the steering gain only when the Autopilot system performance is less than
satisfactory.
Proportional steering gain (PGain) balances rapid steering response and stability. PGain affects the
following:
l Slew Time: The amount of time that the front wheels take to move from the far left to the far
right position and back.
l
Overshoot: The percentage by which the front wheels exceed the commanded angle before
they settle on the correct value.
High Gain Low Gain
Decreases the slew time and increase the
overshoot. This provides rapid responses, but
can cause the steering to exhibit signs of
instability (for example, a tendency to
excessively overshoot).
Increases the slew time and decrease the
overshoot. This improves the stability but can
introduce delays in the steering response and
can cause the vehicle to oscillate from side to
side.
